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

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.

“Significant” issues at Palisades plant resolved, but still a “long way to go"

Company officials who run the Palisades nuclear plant in southwest Michigan say they are improving the safety culture among workers that led to “significant” safety concerns last year. But at a meeting in South Haven Tuesday night, Palisades Site Vice President Tony Vitale said the plant has a “long way to go” to reach “operating excellence.”

Palisades safety rating gets upgraded from one of the worst in the country

On Friday Federal regulators upgraded the safety rating at the Palisades nuclear plant from one of the worst in the country to one of the best. That’s after Palisades passed a major inspection following a number of safety problems last year.

The Nuclear Regulatory Commission says the poor safety culture among workers at Palisades has improved. That culture was blamed for the biggest safety issue that happened in September 2011 when a worker caused an electrical short that resulted in half the control room indicators going dead.

Palisades fixes latest leak, plant now returning to service

The Palisades nuclear power plant is gradually returning to service after a brief shutdown this week.

The Nuclear Regulatory Commission estimates between 5 and 50 gallons of water leaked in the form of steam from a broken valve at Palisades. The slightly radioactive leak was contained and regulators say there was no risk to public safety.

On Sunday the plant shut down when workers discovered steam leaking from the valve. In a written statement, Palisades spokesman Mark Savage says the valve has been replaced.

Palisades nuclear plant passes emergency drill this week with no violations

Palisades sits on Lake Michigan in Covert, Michigan.

Officials from both the Federal Emergency Management Agency and the Nuclear Regulatory Commission shared their preliminary results Friday of an emergency drill at Palisades earlier this week. During the two-day drill officials from the plant in Covert Township had to react to a simulated release of radiation into the environment. Agencies from several counties in Michigan and Indiana took part in the drill as well.

NRC Senior Emergency Preparedness Inspector Bob Jickling evaluated how the licensee, Entergy, responds.
