‘Irreparable’ safety issues: All US nuclear reactors should be taken out of commission
RT | April 9, 2013
All 104 nuclear reactors currently operational in the US have irreparable safety issues and should be taken out of commission and replaced, former chairman of the US Nuclear Regulatory Commission, Gregory B. Jaczko said.
The comments, made during the Carnegie International Nuclear Policy Conference, are “highly unusual” for a current or former member of the safety commission, according to The New York Times. Asked why he had suddenly decided to make the remarks, Jaczko implied that he had only recently arrived at these conclusions following the serious aftermath of Japan’s tsunami-stricken Fukushima Daichii nuclear facility.
“I was just thinking about the issues more, and watching as the industry and the regulators and the whole nuclear safety community continues to try to figure out how to address these very, very difficult problems,” which were made more evident by the 2011 Fukushima nuclear accident in Japan, he said. “Continuing to put Band-Aid on Band-Aid is not going to fix the problem.”
According to the former chairman, US reactors that received permission from the nuclear commission to operate for an additional 20 years past their initial 40-year licenses would not likely last long. He further rejected the commission’s proposal for a second 20-year extension, which would leave some American nuclear reactors operating for some 80 years.
Jaczko’s comments are quite significant as the US faces a mass retirement of its reactors and nuclear policy largely revolves around maintaining existing facilities, rather than attempting to go through the politically hazardous process of financing and breaking ground on new plants.
Though the US maintains a massive naval nuclear program, all of the country’s current civilian reactors began construction in 1974 or earlier, and a serious incident at Three Mile Island in 1979, along with an economic recession, essentially caused new projects to be scrapped.
A modest revival of enthusiasm for nuclear power emerged in the early part of the last decade, leading to the construction of four reactors at existing facilities within the last three years, slated to be completed by 2020. Despite the lack of new projects, the US is still the world’s biggest producer of nuclear power, which represents 19% of its total electrical output.
Fittingly, Jaczko’s comments came during a panel discussion of the Fukushima incident, which has brought greater attention to aging US reactors – some of which were quite similar to the General Electric-designed models overwhelmed by the earthquake and subsequent tsunami in 2011.
In response to those comments, Marvin S. Fertel, president and chief executive of the Nuclear Energy Institute, told the Times that the country’s nuclear power grid has, is, and will operate safely.
“US nuclear energy facilities are operating safely,” said Fertel. “That was the case prior to Greg Jaczko’s tenure as Nuclear Regulatory Commission chairman. It was the case during his tenure as NRC chairman, as acknowledged by the NRC’s special Fukushima response task force and evidenced by a multitude of safety and performance indicators. It is still the case today.”
Since the first nuclear reactor went operational in the US, there have been very few fatal incidents at nuclear power facilities, though there were a number of high profile stories written over the inherent dangers of large nuclear reactors during the mid-1970s. One of the most recent incidents at a US reactor was in April of 2013, when an employee was killed at the Arkansas Nuclear One plant while moving part of a generator.
Jaczko served as chairman of the nuclear regulatory agency since 2009, and according to the Times resigned in 2012 following conflicts with colleagues. He was seen as an outlying vote on a number of safety issues, and had advocated for more stringent safety improvements during his tenure.

US: NRC HALTS NUCLEAR REACTOR LICENSING DECISIONS
Decision Follows 24 Groups’ June Petition in Wake of Major Waste Confidence Rule Decision; Most Reactor Projects Already Stymied by Bad Economics and Cheaper Fuel Alternatives
SACE – August 7, 2012
WASHINGTON, D.C. – The U.S. Nuclear Regulatory Commission (NRC) acted today to put a hold on at least 19 final reactor licensing decisions – nine construction & operating licenses (COLS), eight license renewals, one operating license, and one early site permit – in response to the landmark Waste Confidence Rule decision of June 8th by the U.S. Court of Appeals for the D.C. Circuit.
The NRC action was sought in a June 18, 2012 petition filed by 24 groups urging the NRC to respond to the court ruling by freezing final licensing decisions until it has completed a rulemaking action on the environmental impacts of highly radioactive nuclear waste in the form of spent, or ‘used’, reactor fuel storage and disposal.
In hailing the NRC action, the groups also noted that most of the U.S. reactor projects were already essentially sidetracked by the huge problems facing the nuclear industry, including an inability to control runaway costs, and the availability of far less expensive energy alternatives.
Diane Curran, an attorney representing some of the groups in the Court of Appeals case, said:
“This Commission decision halts all final licensing decisions — but not the licensing proceedings themselves — until NRC completes a thorough study of the environmental impacts of storing and disposing of spent nuclear fuel. That study should have been done years ago, but NRC just kept kicking the can down the road. When the Federal Appeals Court ordered NRC to stop and consider the impacts of generating spent nuclear fuel for which it has found no safe means of disposal, the agency could choose to appeal the decision by August 22nd or choose to do the serious work of analyzing the environmental impacts over the next few years. With today’s Commission decision, we are hopeful that the agency will undertake the serious work.”
Stephen Smith, executive director of Southern Alliance for Clean Energy, petitioner to the Court, said:
“We’re pleased with the Nuclear Regulatory Commission’s ruling; it is long overdue. Nuclear power is not a clean generating source when it creates long-lived radioactive and toxic waste that has no long-term safe disposal technology in place. We believe it is appropriate to halt nuclear licensing decisions and stop creating an inter-generational debt of nuclear waste that will burden our children and grandchildren for centuries to come.”
Lou Zeller, executive director of Blue Ridge Environmental Defense League, another petitioner to the Court, said:
“It appears that the Commissioners have, at least initially, grasped the magnitude of the Court’s ruling and we are optimistic that it will set up a fundamentally transparent, fair process under the National Environmental Policy Act to examine the serious environmental impacts of spent nuclear fuel storage and disposal prior to licensing or relicensing nuclear reactors.”
Former NRC Commissioner Peter Bradford said:
“It is important to recognize that the reactors awaiting construction licenses weren’t going to be built anytime soon even without the Court decision or today’s NRC action. Falling demand, cheaper alternatives and runaway nuclear costs had doomed their near term prospects well before the recent Court decision. Important though the Court decision is in modifying the NRC’s historic push-the-power-plants-but-postpone-the-problems approach to generic safety and environmental issues, it cannot be blamed for ongoing descent into fiasco of the bubble once known as ‘the nuclear renaissance’.”
In June, the following groups filed the petition with the NRC:
• Beyond Nuclear, Inc. (intervenor in Fermi COL proceeding, Calvert Cliffs COL proceeding, and Davis-Besse license renewal proceeding; potential intervenor in Grand Gulf COL and Grand Gulf license renewal proceedings);
• Blue Ridge Environmental Defense League, Inc. and chapters (“BREDL”) (intervenor in Bellefonte COL proceeding and North Anna COL proceeding; previously sought intervention in W.S. Lee COL proceeding);
• Citizens Allied for Safe Energy, Inc. (former intervenor in Turkey Point COL proceeding);
• Citizens Environmental Alliance of Southwestern Ontario, Inc. (intervenor in Fermi COL proceeding and Davis-Besse license renewal proceeding);
• Citizens for Alternatives to Chemical Contamination (intervenor in Fermi COL proceeding);
• Don’t Waste Michigan, Inc. (intervenor in Fermi COL proceeding and Davis-Besse license renewal proceeding);
• Ecology Party of Florida (intervenor in Levy COL proceeding);
• Eric Epstein (potential intervenor in Bell Bend COL proceeding);
• Friends of the Earth, Inc. (potential intervenor in reactor licensing proceedings throughout U.S.);
• Friends of the Coast, Inc. (intervenor in Seabrook license renewal proceeding);
• Green Party of Ohio (intervenor in Davis-Besse license renewal proceeding);
• Dan Kipnis (intervenor in Turkey Point proceeding);
• National Parks Conservation Association, Inc. (intervenor in Turkey Point COL proceeding);
• Mark Oncavage (intervenor in Turkey Point COL proceeding);
• Missouri Coalition for the Environment, Inc. (Petitioner in Callaway license renewal proceeding; intervenor in suspended Callaway COL proceeding)
• New England Coalition, Inc. (intervenor in Seabrook license renewal proceeding);
• North Carolina Waste Reduction and Awareness Network, Inc. (admitted as an Intervenor in now-closed Shearon Harris COL proceeding);
• Nuclear Information and Resource Service, Inc. (intervenor in Calvert Cliffs COL proceeding and Levy COL proceeding);
• Public Citizen, Inc. (intervenor in South Texas COL proceeding; admitted as intervenor in now-closed Comanche Peak COL proceeding; potential intervenor in South Texas license renewal proceeding);
• San Luis Obispo Mothers for Peace, Inc. (intervenor in Diablo Canyon license renewal proceeding);
• Sierra Club, Inc. (Michigan Chapter) (intervenor in Fermi COL proceeding);
• Southern Alliance for Clean Energy, Inc. (intervenor in Watts Bar Unit 2 OL proceeding, Turkey Point COL proceeding, Bellefonte COL proceeding; former intervenor in Bellefonte CP proceeding);
• Southern Maryland CARES, Inc. (Citizens Alliance for Renewable Energy Solutions) (intervenor in Calvert Cliffs COL proceeding);
• Sustainable Energy and Economic Development (“SEED”) Coalition, Inc. (intervenor in South Texas COL proceeding; admitted as intervenor in now-closed Comanche Peak COL proceeding; potential intervenor in South Texas license renewal proceeding).
The 24 groups that sponsored the June 18th petition will strategize in September regarding next steps.
On June 8th, the Court threw out the NRC rule that permitted licensing and re-licensing of nuclear reactors based on the supposition that (a) the NRC will find a way to dispose of spent reactor fuel to be generated by reactors at some time in the future when it becomes “necessary” and (b) in the mean time, spent fuel can be stored safely at reactor sites.
The Court noted that, after decades of failure to site a repository, including twenty years of working on the now-abandoned Yucca Mountain repository, the NRC “has no long-term plan other than hoping for a geologic repository.” Therefore it is possible that spent fuel will be stored at reactor sites “on a permanent basis.” Under the circumstances, the NRC must examine the environmental consequences of failing to establish a repository when one is needed.
The Court also rejected NRC’s decision minimizing the risks of leaks or fires from spent fuel stored in reactor pools during future storage, because the NRC had not demonstrated that these future impacts would be insignificant. The Court found that past experience with pool leaks was not an adequate predictor of future experience. It also concluded that the NRC had not shown that catastrophic fires in spent fuel pools were so unlikely that their risks could be ignored.

The Broken Nuke
By RUSSELL D. HOFFMAN | CounterPunch | July 11, 2012
San Onofre Nuclear (Waste) Generating Station has been shut down for nearly six months, ever since one of the heat transfer tubes inside their new steam generators in Reactor Unit 3 ruptured suddenly and unexpectedly.
The normal pressure difference from one side of the tube to the other is enormous: About 1,000 pounds per square inch, so even a tiny leak spews many gallons of “primary coolant” (which is highly radioactive) into the “secondary coolant loop” (which, ideally, is not radioactive at all). When a leak occurs, the primary coolant flashes to steam as it exits the broken tube, and the steam is so hot it can cut through the tube like a welder’s torch, eventually cutting a complete circle around the tube, releasing it to fling around and damage other tubes.
There are nearly 10,000 U-shaped heat transfer tubes inside each steam generator. They are about the thickness of a credit card and the diameter of your thumb.
Reactor Unit 2 was already shut down for massive repairs and refueling when Unit 3 sprang a leak. Neither unit has operated since then (and the lights have remained on. We do not need San Onofre). An older reactor, Reactor Unit 1, was retired 20 years ago for basically the same reason, and has since been dismantled. It’s time to dismantle Units 2 and 3, too.
SanO’s majority owner and operator, Southern California Edison, recently claimed to have identified the cause of Unit 3′s current problem as “fluid elastic instability”. And although Unit 2 is of identical design and also has two new steam generators which are also experiencing excessive wear, SCE claims Unit 2 will not suffer the same problem if they restart it at reduced power. SCE wants to do that next month, probably at half power, which does NOT mean the pressure differences and flow rates are half as much, because efficiency drops off substantially when the plant is not run at its maximum practical output (and so do profits for SCE!).
If Unit 2 runs without problems, they’ll bump the power up to 60%, then 70% and then 80%. (So far that’s as high as they’ve said they’ll dare to go.) Then they’ll start talking about restarting Unit 3 at reduced power as well.
If nothing ruptures, they’ll shut the reactor down periodically to check for wear, since they can’t tell what’s happening inside the steam generators while the reactor is operating. The extra shutdowns are costly and hold additional dangers. (The Nuclear Regulatory Commission keeps carefully track of how many times a reactor is cycled on and off.)
Restarting either SanO unit should be opposed by everyone in Southern California. It’s not worth the risk.
Fluid elastic instability was first identified around 1970 and occurs when a fluid — usually a steam/water mixture (in this case mostly steam) flows across a bundle of tubes. In the case of San Onofre, the steam/water mixture traverses the tubes at the U-portion of the tubes at their top.
A cascade of tube failures is substantially more likely under fluid elastic instability conditions than most other tube-rupture scenarios. If a cascading tube failure occurs, the fact that SanO’s design has only two steam generators (whereas most Pressurized Water Reactors (PWRs) have three or four) becomes an additional serious liability: The second (only remaining) steam generator has to remove ALL the heat from the reactor. Debris from the first steam generator failure may further complicate matters.
SCE was very reluctant to admit they’ve got a fluid elastic instability problem, and when they made a presentation to the Southern California Association of Governments (SCAG) last week, they didn’t try to explain what fluid elastic instability is. They just said that it was apparently the problem.
However, the phenomenon is described in a 2001 ASME handbook on flow induced vibrations by M. K. Au-Yang: Upon crossing the “critical velocity” the tube vibrations “suddenly rapidly increase without bound, until tube-to-tube impacting or other non-linear effects limit the tube motions.” The vibrations: “become correlated and bear definite phase relationship to one another…”
In other words, the tubes rock back and forth together like people doing “the wave” or some other motion in a stadium.
Fluid elastic instability is difficult to model using computer simulations and SCE did not do full-scale modeling of the new steam generator design. They also skipped full-scale hot testing after installing the new steam generators in 2010 and 2011.
When a tube started to leak in January 2012, the reactor operators did NOT suspect fluid elastic instability, and did NOT do the immediate prudent thing: Shut down the reactor.
Instead, they kept running at full power until it was determined that the leak was growing — always a bad sign. Permitted leakage rates, and total amounts, would have both soon been exceeded. Normally, when the reactor is shut down for routine maintenance, faulty tubes are plugged. This process continues for the life of the plant or until so many tubes are plugged that the steam generators have to be replaced. When the plant was built, it was believed that the steam generators would last the full life expectancy of the plant. But throughout the nuclear industry, replacing steam generators has become a huge business.
Fluid elastic instability is relatively rare but is much more frightening than a typical steam generator tube leak. Some leaks are left to spew, because rather than grow, they clog up with crud and stop spreading. But growing leaks cannot be ignored.
Of the nearly 40,000 tubes inside the four new steam generators in the two operating reactors at San Onofre, more than 1,300 were found to have excessive wear to such a degree that they needed to be plugged. About 10% of those were pressure-tested before being plugged, and eight failed the pressure tests — some failed at pressures BELOW standard operating pressure!
SCE officials are very reluctant to say how many tubes have failed in Unit 2, stressing that “only two” tubes indicated tube-to-tube wear, which, they feel, was probably caused by turbulence, not fluid elastic instability. They aren’t certain, though, and just because fluid elastic instability hasn’t been experienced in Unit 2 yet, doesn’t mean it can’t happen there, either under normal operating conditions or during an emergency.
SCE has no idea when fluid elastic instability might occur. Their computer models are known to have been off by 300 to 400 percent. Flow rates are known to be way too high, and there is way too much steam and not nearly enough water at the top of the tubes (a mixture with more water would have been much better at dampening vibration).
Maybe SCE is right that lowering the power output will ensure safe operation. But what if they’re wrong? SCE wants to experiment with all our lives.
And let’s say they succeed. Let’s say they get the reactors operating again. Then, they will just go back to producing more spent fuel nuclear waste, a growing problem for which there is still no solution. It will mean the next time there is an earthquake or a tsunami, San Onofre will threaten our farmlands, our cities, and our lives once again. It will mean San Onofre will continue to threaten SoCal at least until the NRC relicenses the plant in 2022/2023, and then for 20 more years after that (and so on ad infinitum). The NRC has never denied a nuclear power plant a license renewal in its history, and is especially unlikely to do so in California where new nuclear power plants are forbidden by state law.
San Onofre is shut down today because it was poorly designed, poorly constructed, and poorly operated. Let’s keep it shut down. It’s not going to get any better.

“There’s enough surplus power in this region to turn off Indian Point tomorrow”
By JOHN RAYMOND | CounterPunch | June 1, 2012
“Shut it down! Shut it down! Shut it down!” rang through the cavernous grand ballroom of the Doubletree Hotel in Tarrytown, NY, last week when the Nuclear Regulatory Commission staged an Orwellian charade promoted as an “open house” held to reassure the public that the Indian Point nuclear power plant was, as the New York Post headlined the following day, “Still Safe!”
The NRC’s annual “safety assessment” of the plant, which sits on the Hudson River 30 miles north of New York City, was based on 11,000 hours of ”inspection activities.” It found that Indian Point performed “within expected regulatory bounds” and the 25 matters that do require attention but “no additional NRC oversight,” are ‘low risk’, or have “very low safety significance.”
“So,” the Post mused, “will this finally silence the ‘shut it down’ crowd? … Don’t hold your breath.”
But do keep your fingers crossed…if you’re one of the 17.5 million people living within 50 miles of the plant…
“The NRC’s annual assessment completely fails to address the public’s primary concerns about Indian Point — evacuation planning, earthquake risk and nuclear waste storage post-Fukushima,” said Phillip Musegaas, a lawyer with Riverkeeper, an environmental group based in Ossining, NY.
Those concerns were addressed in Riverkeeper’s briefing held in the rear of the ballroom prior to the NRC’s hearing that night. Some highlights:
Manna Jo Green, a member of the town council of Rosendale and Environmental Director of Clearwater, who recently toured the plant with the Atomic Safety and Licensing Board: “We are calling for expansion of the evacuation plan from 10 miles to 50 miles and hardening of the fuel pools. There is no protection for those fuel pools…You couldn’t see the fuel rods in fuel pool 2 because the water was so murky… it is so densely crowded with fuel rods, you can’t even get equipment in to fully inspect it …”
Like Riverkeeper, Clearwater in Beacon, NY has filed multiple contentions with the NRC in the legal fight to deny Entergy Corporation a 20-year license extension for Indian Point. Current licenses for the two operating reactors expire in 2013 and 2015. Relicensing hearings are expected to begin in October.
John Armbruster, a seismologist with Lamont Doherty Earth Observatory of Columbia University, cited the study, published in 2008, that revealed there was a second fault line passing near Indian Point in addition to the Ramapo fault line.
“We believe this is a significant new development in what might happen to Indian point. We have been asking since 2008 for our new results to be incorporated into the hearings for the relicensing of Indian Point – and that has been rejected as ‘outside of scope’. What was done when Indian Point was designed 40 years ago is obsolete and Fukushima tells us we have to prepare for the things that are very unlikely.”
Peter Rugh of Occupy Wall Street’s Environmental Solidarity Work Group: “The NRC has issued untold numbers of exemptions to Indian point – untold because they don’t keep track of the safety exemptions they grant to this corporation and to other nuclear operators. Entergy took in 11 billion in 2011 so they can afford to take every possible safety measure here, including shutting down…We want the workers at these plants to be retrained in the green energy sector. We must offer them better employment opportunities than being the gravediggers for New York City, for Westchester County, and for New Jersey.”
Paul Gallay, Executive Director of Riverkeeper, countered claims that shutting down Indian Point would cause an energy shortage and lead to blackouts. Results of a study commissioned by Riverkeeper and the National Resources Defense Council published earlier this year concluded otherwise.
“There’s enough surplus power in this region to turn off Indian Point tomorrow and we won’t have any kind of shortage if we don’t do another thing until 2020,” Gallay said. “In the meantime, you can build two Indian Point’s worth of replacement power. You can save 30 percent of our power needs just by energy efficiency… We do not need the power — they want to fool you into believing we do.”
During the open session, an NRC panel sat at the front of the room but no presentation was made to the public and no explanation of the safety “assessment” was given. NRC posters were on display in the hallway outside the ballroom, and Indian Point inspectors were available for questions. But not for answers.
Stepping up to the mike, Mark Jacobson, a co-founder of the Indian Point Safe Energy Coalition (IPSEC), asked, “Where is Entergy? Why isn’t Entergy in the room? We want to ask them questions.”
Getting no reply, Jacobson told the panel that he had questioned inspectors about the status of the radioactive leak under Unit 2’s transformer yard. “They said they didn’t know. It’s a leak that’s been likened to the size of the Central Park reservoir… and we can’t find out about it at this annual meeting. Who are we supposed to ask?”
Indian Point’s leaks are contaminating groundwater and the nearby Hudson River with radioactive carcinogens including strontium-90, cesium 137, and iodine 131.
The impossibility of evacuation in the event of an accident at Indian Point stirred the loudest protest of the night.
Citing the recent news report from the Associated Press that revised – and watered down – emergency planning and evacuation procedures had been adopted late last year without broad public input, Marilyn Elie, also of IPSEC, said, “Nobody has known about this and you dare, in post-Fukushima, you dare to weaken and have fewer evacuation drills.
“Region 1 could not even tell the commissioners this is not a good idea to secretly pass a new evacuation plan, to not let the stakeholders know…We need to call right now for a whole new NRC – all the commissioners need to be withdrawn – and it needs to go right down the line until it gets to Region 1.”

Vermont Yankee future in question again
NRC asked to investigate recent pattern of failures
By Lucas W Hixson | Enformable | March 16, 2012
The Vermont Yankee nuclear power plant is operating at reduced power due to problems with the condenser tubes, which are reported to be leaking. Most nuclear power plants replace their condenser at between 20 and 30 years of continued operation, while Vermont Yankee’s condenser has been in operation over 39-years.
Condenser leaks adversely affect reliability and the water quality of the water that is used inside the nuclear plant as the primary reactor coolant. Cooling for the plant’s steam condenser is provided from the adjacent Connecticut river. At the beginning of February, nuclear engineers at the plant discovered that the condenser was not operating efficiently. There have been a string of outages in recent months that Yankee has had to reduce power because of problems with the condenser.
Condensers have been known to fail catastrophically, as occurred at Entergy’s Grand Gulf Plant, shutting down the plant for several months. Thus failure of the Condenser would have a tremendous impact upon Vermont Yankee’s ability to operate within cost-effective margins. The condenser has thousands of small tubes, that are made out of admiralty metal, copper, stainless steel, or titanium. The Condenser has two major functions:
- Condense and recover the steam that passes through the turbine (Condensers are used in all power plants that use steam as the driving force)
- Maintain a vacuum to optimize the efficiency of the turbine.
A regional spokesman for the NRC said the plastic coating Entergy used on the condenser tubes has caused the system to run less efficiently. If the epoxy is the source of the issue, the plant will have to run at 50 percent power levels while workers strip epoxy off of the tubing in each of the sections of the condenser. Vermont Yankee spokesman said the condenser has been upgraded over time and the tubes were “re-sleeved” several years ago.
The cause of the “reduced performance” of the condenser isn’t clear at this point. Last week the back pressure level went up to 4.5 pounds per square inch. The maximum level for the plant is 5 psi, according to Sarah Hofmann, deputy commissioner of the Department of Public Service. At 7 psi, the plant is designed to SCRAM.
The state says Yankee technicians made a mistake and left a metal plate inside the component as they were trying to troubleshoot the issue last week. The plate was a piece of metal large enough for workers to stand on. Neil Sheehan is a spokesman for the Nuclear Regulatory Commission said the agency is aware of the incident, adding, “ It’s an issue that’s affected not only Vermont Yankee but numerous other plants over the years where there’s foreign material that’s left behind when a job is completed. We don’t think that’s acceptable and we certainly had that discussion with them and our inspectors will certainly be addressing that in an upcoming inspection report.”
Entergy is unlikely to replace the condenser until a decision is made in its favor to extend the plants current operating license in Vermont, which expires on March 21st, 2012, but the NRC issued a new operating license last year allowing the plant to continue operating until 2032.
In testimony, Fairewinds Associates noted that rather than invest $200,000,000 (in 2016 dollars) in a new condenser, Entergy may choose instead to shut down the plant as it would be difficult to recoup such a large investment during the final years of the plants life. Especially if Entergy is losing more than it is profiting for extended periods, which may then cause the licensee to make drastic economic decisions in the face of mounting pressure to block the extension of the plants operating license. Entergy has admitted Vermont Yankee is a minimal profit producer and additional costs may prove too expensive, especially with the added costs of post-Fukushima upgrades, and conditions imposed after the NRC issued its 20-year extended license.
The NRC recently released an annual report on Yankee that cited a number of what it called non-safety issues at the plant. Since Louisiana-based Entergy Corporation purchased Vermont Yankee from state utility companies in 2002, the plant has had a string of physical plant problems including a water tower collapse in 2007 and a transformer fire. In January 2010, the company revealed that underground pipes at the plant were leaking tritium into soil on the compound, which is located on the banks of the Connecticut River.
The recent incident prompted the Shumlin Administration to ask federal regulators about a recent series of human errors at the plant. Public Service Commissioner Elizabeth Miller wrote Thursday to the head of the NRC’s Northeast region to say she’s concerned about what she called a pattern of human errors at the Vernon reactor during the past 15 months.
Commissioner Miller says the most recent incident of the metal plate left inside the condenser raised questions about whether Yankee was experiencing a pattern of human errors. “In looking at the reports I had a concern that there had been a number of incidents and felt it was appropriate to ask the NRC to explain why that pattern of incidents didn’t deserve further attention or further action by the NRC and so that’s why we sent the letter.”
Miller lists five errors, ranging from failure to remove a plastic cover from a pump before it was installed to inaccurately measuring the dose rate from a shipment of radioactive waste. Miller’s letter to the NRC cites other mistakes, including a case last fall when Yankee technicians misread a work order and shut down a breaker which resulted in a brief loss of the shutdown cooling system, and another case in December when workers mistakenly tripped the wrong diesel back-up generator.
The NRC labeled all five incidents as minor, but Miller is questioning why they aren’t being considered as part of a pattern. Yankee spokesman Larry Smith said he could not comment on Miller’s letter. The NRC said it would review it. In addition to conducting two reviews in 2012 — at mid-cycle and end-of-cycle — the NRC will also review Yankee’s implementation of an industry initiative meant to control degradation of underground piping.
In 2009, the Vermont Senate voted to deny permission for Entergy to obtain a certificate of public good from the Public Service Board for re-licensure of the plant. In February 2010, the Vermont Senate voted 26 to 4 against re-licensing of the Vermont Yankee Nuclear Plant after 2012, citing radioactive tritium leaks, misstatements in testimony by plant officials, and other documented on-site events. Entergy sued the state over several statutes, including one that gives Vermont jurisdiction over the continued operation of the plant past the 40-year deadline and a say in the long-term storage of nuclear waste on site.
A state law that prevents the plant from storing spent fuel at Vermont Yankee after that date without approval from the Public Service Board. Last week the board questioned whether it had the ability to let Vermont Yankee keep producing spent fuel and pushed Entergy attorneys on why they hadn’t addressed the impending issue earlier. Federal district court Judge J. Garvan Murtha ruled the Atomic Energy Act pre-empted the two state laws, but his decision left the Public Service Board’s discretion intact. The Public Service Board held a status conference March 9 at which they would not guarantee that the plant would keep operating, and briefs are due Friday.
When the board reopened the proceeding and asked whether the plant could continue to operate, Entergy fired off an immediate request to the court asking it to let the plant operate after March 21, implying it might continue operating, even if the board says it should not.
“[O]n March 9, 2012, the PSB made clear that it does not necessarily agree with the AG’s and the DPS’s view. In the event that the PSB ultimately disagrees, Plaintiffs will be forced either to cease operating or, if they defy the PSB by continuing to operate, to face the prospect of a diminished credit rating, a loss of crucial employees, and a demerit in the PSB’s consideration of Plaintiffs’ petition for a new CPG.”
Entergy has a track record of deferring maintenance, exampled by the 2007 collapse of the cooling towers, was found to be caused by corrosion in steel bolts and rotting of lumber. Some still think that a corporation that buys an aged nuclear plant fully aware of the pending decommissioning agreement with the state, ought to be bound to decommission it. However, right in the middle of the Fukushima disaster the NRC grants another 20 years to an old, trouble ridden plant, doesn’t that just beat all…

No Nuclear Nirvana
By ROBERT ALVAREZ | CounterPunch | March 6, 2012
Is the nuclear drought over?
When the Nuclear Regulatory Commission (NRC) recently approved two new nuclear reactors near Augusta, Georgia, the first such decision in 32 years, there was plenty of hoopla.
It marked a “clarion call to the world,” declared Marvin S. Fertel, president of the Nuclear Energy Institute. “Nuclear energy is a critical part of President Obama’s all-of-the-above energy strategy,” declared Energy Secretary Chu, who traveled in February to the Vogtle site where Westinghouse plans to build two new reactors.
But it’s too soon for nuclear boosters to pop their champagne corks. Japan’s Fukushima disaster continues to unfold nearly a year after the deadly earthquake and tsunami unleashed what’s shaping up to be the worst nuclear disaster ever. Meanwhile, a raft of worldwide reactor closures, cancellations, and postponements is still playing out. The global investment bank UBS estimates that some 30 reactors in several countries are at risk of closure, including at least two in highly pro-nuclear France.
And Siemens AG, one of the world’s largest builders of nuclear power plants, has already dumped its nuclear business.
Recently, Standard and Poor’s (S&P) credit rating agency announced that without blanket financing from consumers and taxpayers, the prospects of an American nuclear renaissance are “faint.” It doesn’t help that the nuclear price tag has nearly doubled in the past five years. Currently reactors are estimated to cost about $6 to $10 billion to build. The glut of cheap natural gas makes it even less attractive for us to nuke out.
How expensive is the bill that S&P thinks private lenders will shun?
Replacing the nation’s existing fleet of 104 reactors, which are all slated for closure by 2056, could cost about $1.4 trillion. Oh, and add another $500 billion to boost the generating capacity by 50 percent to make a meaningful impact on reducing carbon emissions. (Nuclear power advocates are touting it as a means of slowing climate change.) We’d need to fire up at least one new reactor every month, or even more often, for the next several decades.
Dream on.
Meanwhile, Japan — which has the world’s third-largest nuclear reactor fleet — has cancelled all new nuclear reactor projects. All but two of its 54 plants are shut down. Plus the risk of yet another highly destructive earthquake occurring even closer to the Fukushima reactors has increased, according to the European Geosciences Union.
This is particularly worrisome for Daiichi’s structurally damaged spent fuel pool at Reactor No. 4, which sits 100 feet above ground, exposed to the elements. Drainage of water from this pool resulting from another quake could trigger a catastrophic radiological fire involving about eight times more radioactive cesium than was released at Chernobyl.
Ironically, the NRC’s decision to license those two reactors has thrown a lifeline to Japan’s flagging nuclear power industry (along with an $8.3-billion U.S. taxpayer loan guarantee). Toshiba Corp. owns 87 percent of Westinghouse, which is slated to build the new reactors. Since U.S.-based nuclear power vendors disappeared years ago, all of the proposed reactors in this country are to be made by Japanese firms — Toshiba, Mitsubishi, and Hitachi — or Areva, which is mostly owned by the French government. According to the Energy Department, “major equipment would not be manufactured by U.S. facilities.”
For Southern Co., which would operate the Vogtle reactors, the NRC’s approval is just the beginning of a financial and political gauntlet it must run through. Over the strenuous objections of consumers and businesses, energy customers will shoulder the costs of financing and constructing this $17-billion project, even if the reactors are abandoned before completion. If things don’t turn out, U.S. taxpayers will also be on the hook for an $8.3-billion loan guarantee that the Energy Department has approved.
The Congressional Budget Office and the Government Accountability Office estimate that nuclear loan guarantees have a 50/50 chance of default.
Nearly four decades after the Three Mile Island accident, nuclear power remains expensive, dangerous, and too radioactive for Wall Street. The industry won’t grow unless the U.S. government props it up and the public bears the risks.
