A critical two week federal inspection of the Palisades nuclear power plant begins Monday.

Nuclear Regulatory Commission inspectors want to determine if Palisades’ owners have addressed problems that have raised questions about the nuclear plant’s “culture of safety”.

The problems have resulted in four unscheduled reactor shutdowns.

“It’s a very important inspection for us,” says Anthony Vitale, the plant’s site vice president,  “And it will give us a very good scrub as to where we are. We expect to come out of that with very good ratings.”

The owners of the Palisades nuclear power plant promised last night to improve their “culture of safety."   

But dozens of people at the public meeting doubted that promise.   Catherine Sugas spoke for many people who attended the meeting when she questioned why the problem plagued nuclear power plant is still operating.

“If you can’t shut down a plant that’s dangerous…what are you?    How can you keep a plant going that’s obviously dangerous,” Sugas asked a panel from the Nuclear Regulatory Commission.

The safety of west Michigan’s Palisades nuclear power plant will be the topic of a public meeting tonight in South Haven.

Palisades has one of the worst safety ratings in the country.

Maintenance mistakes and other problems led to four unscheduled reactor shutdowns at Palisades in 2011.  And there have been more problems this year.

Dozens of people crowded around several small tables at conference center in South Haven, six miles north of the Palisades nuclear plant.

Each table features a different area of concern or interest at the plan; the reactor vessel’s embrittlement factor, a water tank leak, a coupling failure, replacement of a cooling tower, how spent fuel is stored, community projects Entergy supports.

Engineers and project managers point to pictures and diagrams to help answer questions. There are little freebies and even a raffle for a new Ipad.

The plant has one of the worst safety ratings in the country after a series of problems in 2011.

New documents show a team of nuclear regulators will begin a major inspection of the Palisades nuclear power plant this month. The inspection is a direct result of the plant’s downgraded safety rating that was issued earlier this year.

Palisades Nuclear Power Plant was shut down this past Sunday for a water leak inside a containment building. This is the second leak at the plant this summer that has triggered a shutdown.

The plant is operated by Entergy Nuclear Operations and is located in Covert, Michigan near South Haven.

Today, the Nuclear Regulatory Commission announced that a three member inspection team is at Palisades looking into the problem:

The three member inspection team will begin work Wednesday and look into the circumstances surrounding the leak. They will review the utility’s monitoring of the leak and subsequent plant shutdown, verify the adequacy of radiological controls, evaluate any potential degradation, and review the plant’s repair actions. The team will also review the plant’s reporting requirements and their plan for addressing the cause of the event.

Michigan Radio's Lindsey Smith covered the shutdown in yesterday's Environment Report segment. She spoke with Entergy spokesman Mark Savage.

Savage says they’ve determined that a “control rod drive package” is the source of the leak. There are 45 of these control rods. Plant operators can raise or lower control rods to control the rate of the nuclear reaction.

“And occasionally these control rod drives will have a problem. In this case we couldn’t identify it until we actually shut the plant down. So we take aggressive action to shut the plant down, do the right thing, make the repairs and return the plant to service," Savage said.

Palisades has been the focus of significantly more oversight from federal regulators over the last year.

The Palisades Nuclear Power Plant near South Haven has shut down again.

This is the second time this summer Entergy Corporation has had to shut down the plant for repairs. 

The plant shut down to refuel in April; that was normal. It restarted in early May.

But then a water leak in a tank above the control room caused the plant to shut back down just a few weeks later. Those repairs took a month and on July 11th the plant started up again. Though that leak appears to be fixed, it is still under investigation by special federal agents with the Nuclear Regulatory Commission.

But as it returned to service in July, Palisades spokesman Mark Savage says operators discovered a different water leak – this time in the building that holds the nuclear reactor. In a written statement, Savage called the leak “minor.”

The company noticed this leak when they restarted the plant after fixing that first leak in a tank above the control room. This leak is in a different area of the plant – the containment building. This building holds the nuclear reactor itself.

Prema Chandrathil is a spokeswoman for the Nuclear Regulatory Commission.  She says the leak is not a threat to public health.

“It’s contained and it goes into the plant’s waste storage tank," Chandrathil said.

Chandrathil says the situation at Palisades is “serious” though. The NRC now has a specialized inspector to assist regular inspectors at the plant while the company makes repairs.
