A timeline of incidents at #Palisades #Nuclear Power Plant since 2007

Published: May. 12, 2013

"COVERT TOWNSHIP, MI -- The leak that shut down Palisades Nuclear Power Plant May 5 is one of a series of incidents that have bedeviled the nuclear reactor in recent years.

"#Entergy Corp. bought Palisades from Consumers Energy in 2007 for $380 million. The one-reactor plant, which is located along #LakeMichigan in #CovertTownship, supplies about 20 percent of the utility's power. The facility came online in 1971 and its license runs until 2031 [it was decommissioned in 2022].

"Below is a timeline of incidents at Palisades since 2007, based on NRC reports and previous MLive/Kalamazoo Gazette articles.

2007 -- Palisades' head of security resigned amid revelations he had fabricated some of his credentials.

2008 -- An NRC safety assessment found Palisades failed "to recognize and assess the impact of radiological hazards in the workplace." The NRC found that Palisades failed to determine how much radiation employees were exposed to after radiation monitors worn by the workers warned of an exposure.

August 2008 -- Five workers were trapped for 90 minutes inside a high-temperature area when a hatch malfunctioned. The NRC launched a probe and found the plant did not take proper precautions to prevent such occurrences.

2009 -- During an inspection, the NRC found that workers failed to notice a problem in the pool where spent fuel rods are kept. The finding, labeled a "low to moderate safety" risk that did not endanger the public, kept Palisades on the NRC's list of plants that required additional regulatory oversight for a second year. The plant's 2009 safety assessment also found problems with human performance regarding "error-prevention techniques."

May 2010
-- A Palisades manager left the control room without following protocol and the event was not reported within 24 hours, the NRC found.

January 2011
-- Palisades operated at 55 percent power for eight days after a cooling-water pump lost power when an electrical bus failed. The event did not represent a threat to health and safety, the NRC said.

May 2011
-- While NRC inspectors were conducting a routine test of the plant’s auxiliary feed water system, a turbine-driven pump was tripped. Investigators found a component of the pump that was greased and should not have been. The NRC classified the event as a "low to moderate" safety significance.

August 2011
-- The NRC launched a special inspection after the failure of a coupling that holds pipes together. It found Palisades did not follow industry standards when choosing the coupling and the cracking was preventable. Palisades replaced all couplings.

September 2011
-- Palisades shut down between Sept. 16 and Sept. 20 for repairs, after workers discovered a leaking valve in the system that cools the reactor.

September 2011
-- Palisades shut down for a week after a breaker fault in the plant's electrical system Sept. 25, when a worker performing maintenance on an electrical panel when a piece of metal came into contact with another metal piece and caused an arc. There were no injuries reported. The NRC launched a special investigation, the second in two months. The investigation found that during the incident, which it named of "substantial significance to safety," Palisades did not follow proper safety protocols before the shutdown.

November 2011
-- The NRC bumped Palisades down a level to the Regulatory Response column as a result of the May 2011 incident.

January 2012
-- Palisades shut down for 3-1/2 days to repair a wearing seal on a control rod mechanism.

February 2012
-- The NRC downgraded Palisades to the third regulatory column, making it among the four-worst performing reactors in the U.S. The downgrade came as a result of the two special investigations launched in 2011.

June 2012
-- Palisades shut down for a month to repair a leak in its safety injection refueling water tank. Numerous cracks were found within the 300,000-gallon storage tank, according to reports. When the plant returned to service, the tank was still leaking, but due to its size, it did not pose a safety risk, the NRC found.

July 2012
-- An independent review of Palisades found "examples of a lack of accountability at all levels."
The study, conducted by Conger & Elsea Inc. in January and February 2012, looked at plant operations related to human performance, safety-conscious work environment, problem identification and resolution.

August 2012
-- Palisades shut down for 18 days to repair a leak in the control rod mechanism drive in the containment building. The NRC sent a three-inspector team and launched a special inspection of the pressure-boundary leak. During the 30 days before the location of the leak was discovered, up to 10,000 gallons of radioactive water leaked from the containment vessel. The water was contained and did not pose a safety risk to the public, the NRC found.

September 2012
-- An NRC inspector found what it characterized as a small leak in a valve in the service water system. The water was not radioactive and did not represent a health or safety risk, the NRC said.

November 2012
-- Palisades shuts down for three days to repair a steam leak inside the plant's auxiliary building.

November 2012
-- The NRC upgraded Palisades after an 11-day inspection in September found that Entergy had made improvements and addressed deficiencies. The NRC ordered an additional 1,000 hours of inspections in 2013, on top of the standard 2,000 hours.

February 2013
-- Palisades shut down for six days to repair a leak in the component cooling water system. It was leaking 35 gallons of non-radioactive water an hour before the shutdown, the NRC said. The leak did not represent a threat to the public or the plant, the NRC said.

March 2013
-- Palisades was one of three U.S. plants with significant safety events, or "near-misses" in the past three years, according to a report by the independent Union of Concerned Scientists. The near-misses at Palisades resulted from long-standing problems, the UCS said, and it charged the NRC with failing to enforce violations.

May 2013
-- On May 5, Palisades shut down after the leak in the safety injection refueling water tank accelerated from one a day to 90 gallons within a 24-hour period, the NRC said. On May 4, before the shutdown, some 79 gallons of radioactive water from the tank went down a drain into a capture basin, where it was extremely diluted, according to the NRC, and ended up in Lake Michigan. The NRC has sent an additional inspector to Palisades, and one of its health physicists is also investigating the incident. As of May 10, Palisades was still offline while workers and inspectors search for the source of the leak and make repairs."

#Palisades #nuclear plant gets $150 million in #Michigan budget

By Sheri McWhirter, Jul. 03, 2023

"Michigan lawmakers included $150 million toward the effort to restart the Palisades nuclear plant as part of a record $81.7 billion state budget passed last week.

"State officials contributed the millions in taxpayer dollars toward #Holtec International’s effort to get the nuclear plant upgraded and fired back up to provide 800 megawatts of carbon-free, base load power as the energy sector transitions away from fossil fuels. If it happens, it would be the first nuclear plant nationwide to return to generating power after being decommissioned.

"The plant was closed last year when its fuel ran out and the owner sold the facility to Holtec. The new owner has now twice applied for federal money to help get the plant operational again.

"The Biden administration has a $6 billion fund within the U.S. Department of Energy intended to preserve the U.S. nuclear reactor fleet and energy sector jobs.

"[...] Power generation at nuclear plants does not generate greenhouse gas emissions that drive climate change, like burning fossil fuels does. However, some #environmental advocates remain concerned about ecological #degradation from needed #uranium #mining and #radiation risk from #ToxicWaste nuclear plants produce."

Biden admin offers $1.2 bln for distressed, shut nuclear plants

"WASHINGTON, March 2 (Reuters) - The Biden administration said on Thursday it is offering $1.2 billion in aid to extend the life of distressed nuclear power plants which, for the first time, could offer funding to a plant that has recently closed.

"President Joe Biden's climate team believes #nuclear power is a crucial source of virtually carbon-free [NUCLEAR IS NOT CARBON FREE] electricity needed to be maintained and expanded to reach his pledge of what it calls 100% clean electricity by 2035.

"But faced with rising security costs and competition from #wind and #solar energy and power generated with cheap natural gas, about a dozen U.S. reactors have closed since 2013, leaving 92 across the country.

"Critics of nuclear power worry about the buildup of #radioactive waste stored at plants around the country and warn of the risks to human health and #nature, while others have called for nuclear nonproliferation.

"The funding comes from the $6 billion Civil Nuclear Credit program, created by the 2021 infrastructure law, and will be distributed by the Department of Energy (#DOE).

"In this second round of program funding, the money is available to plants at risk of closure within a few years, but also for the first time, plants that have stopped operating after Nov. 15, 2021.

"'Expanding the scope of this... funding will allow even more nuclear facilities the opportunity to continue operating as economic drivers in local communities that benefit from cheap, clean [sic], and reliable power,' Energy Secretary Jennifer Granholm said.

"That apparently allows the #Palisades plant in #Michigan to apply. It closed in May 2022, nearly two weeks earlier than its planned date, after then-owner Entergy Corp discovered a coolant system leak.

"Holtec International, the current owner, had applied for the first round of funding, but the DOE rejected it. Holtec's application had surprised some officials because reviving plants after closure would be a costly process and because reopening a decommissioned nuclear plant is associated with potential risks involving radioactive materials."

#Palisades Nuclear Plant history: The problems started early

By Yvonne Zipp, Aug. 24, 2014

- The first year of operation proved uneventful. But then there were three shutdowns in 1973 — with the final starting in August of that year and lasting until March 1975.

- In 1979, the NRC fined Palisades $450,000 — with the regulatory body and the plant ultimately settling for $225,000, the largest single fine the plant has paid.

- The years 1993 and '94 marked a particularly troubled time for the plant. During a refueling shutdown in June 1993, workers discovered a broken fuel rod and leaking pipes and valves, causing the plant to remain shut down until November.

- Then in December 2007, tritium was found in a test well at levels above the Environmental Protection Agency's limits for drinking water.
