Palisades nuclear power plant shuts after water leak

COVERT TOWNSHIP, Mich. (AP) - Operators of the Palisades Nuclear Power Plant in southwestern Michigan say they removed it from service because of a water leak.

The plant operators say they took the plant off line Sunday morning for inspections and repairs to the safety injection/refueling water tank. They say there is no risk to the public.

The plant is along Lake Michigan's shoreline in Van Buren County's Covert Township, about 80 miles east-northeast of Chicago.

Union of Concerned Scientists’ nuclear expert in Michigan to discuss Palisades

The director of the nuclear safety project for the Union of Concerned Scientists is in Michigan to talk about the Palisades nuclear power plant.

David Lochbaum is critical of the Nuclear Regulatory Commission in his latest report on nuclear safety released in March.

Lochbaum says the NRC should have fined Entergy, the company that owns Palisades, over a water leak last summer.

Palisades says plant on “road to recovery,” not all convinced

Two tables full of NRC officials from the region and Washington DC answered questions from the public during a meeting Tuesday night.

Entergy Corporation, the company that owns the Palisades nuclear power plant, says the plant is on the “road to recovery” after a series of safety problems.

Federal regulators recently upgraded the plant’s safety rating from one of the worst in the country after it passed a major inspection last fall.

Palisades Vice President Tony Vitale outlined the steps he and his staff took last year to improve human performance at the plant, one of the main reasons for the safety rating downgrade.

He says a recent, independent study of the safety culture shows the plan is paying off.

Are the safety problems at Palisades getting any better yet?

This week Nuclear Regulatory Commissioner William Magwood came to South Haven to tour the Palisades nuclear power plant in nearby Covert Township.

Magwood did not respond to requests to comment on how his tour went or why he chose to come.

He’s the second commissioner to visit the plant in less than a year. NRC spokeswoman Viktoria Mitlyng says that many high-level visits in such a short time is “not necessarily” uncommon.

“You can draw your own conclusions about that because I cannot do that for you,”Mitlyng said.

Kevin Kamps is with the anti-nuclear watchdog group Beyond Nuclear. Unlike the media, he and several others got a chance to sit down with Commissioner Magwood.

“There were some hints around the edges that it’s because of the problem plagued nature of Palisades and he even used the word disappointment for continued problems out there,” Kamps said.

2012 was a crazy year for the Palisades. Get a feel for it in our timeline on Palisades here.

Regulators: chance of Palisades vessel break resulting in radiation release – one in a million

During an online public meeting Tuesday night, federal nuclear regulators reiterated their belief that the Palisades nuclear power plant in Covert, Michigan, near South Haven is safe.

The Nuclear Regulatory Commission hosted the meeting to talk with the public about the strength of the vessel that contains the nuclear reactor and fuel. Radiation, high pressure and temperatures over long periods of time make the metal vessels in all pressurized water reactors more vulnerable at nuclear plants.

Palisades is the oldest nuclear power plant in the state, and it’s got one of the most brittle reactor vessels in the country. Older nuclear plants like Palisades have some copper in the mostly steel vessel; later designs have stronger steel, regulators said.

Mark Kirk is a Senior Materials Engineer in the Office of Nuclear Regulatory Research at the NRC.

“It’s unquestionably true that Palisades, one of the welds in Palisades, is one of the most embrittled in all of the plants operating in the US,” Kirk said. “Even so, Palisades continues to operate in compliance with the relevant NRC rules.”

By 2017 the plant’s vessel will become too brittle to legally operate.

Federal regulators to talk about Palisades’ aging nuclear vessel in public meeting online

The nuclear reactor vessel is inside the taller containment building on the left.

Nuclear regulators will discuss the risk of “pressurized thermal shock,” one of the biggest fears anti-nuclear groups have about the Palisades nuclear power plant during an online meeting Tuesday.

Over time the radiation, extreme pressure and heat from the nuclear reactor wear on the metal vessel that contains it. That’s called embrittlement.

Palisades: a year in review

Credit Lindsey Smith / Michigan Radio
NRC officials Jack Giessner, Tom Taylor, April Scarbeary, Robert Orlikowski, and Chuck Castro answer questions from the public.

The Palisades Nuclear Power Plant near South Haven has been going through some significant challenges over the past couple of years. It’s been shut down eight times in two years, and federal regulators downgraded its safety rating to one of the worst in the country.

Michigan Radio's Lindsey Smith has been writing about the plant through the turmoil. She joined me on today's Environment Report to take a look back at the events of the past year.

TIMELINE: 8 shutdowns at Palisades Nuclear Power Plant in past 2 years

Michigan Radio has been following the problems at the Palisades Nuclear Power Plant for the last several years.

Our West Michigan reporter, Lindsey Smith, has been on top of all the leaks, shutdowns, public meetings and visits from the U.S. Nuclear Regulatory Commission.

Last February, after five shutdowns in one year, the NRC downgraded Palisades' safety rating. It was rated as one of the four worst in the country.
