Residents, regulators, activists and plant workers mingle at Palisades’ open house

Around 80 people came to Palisades' open house Tuesday night at a conference center in South Haven.

You can listen to a related Environment Report segment above or read an expanded version below.

Even though Palisades is temporarily shut down, the nuclear power plant last night held a public open house it had scheduled more than a month ago.

In a small conference center in South Haven Tuesday night, anti-nuclear activists mingled with federal nuclear regulators, residents, and plant workers. Palisades Site Vice President Tony Vitale says that's a good thing. He says the open house is designed for people in the community to come talk to some of the plant workers firsthand.

“We’re not hiding anything. We want to run, and will run, and I will demand we run a transparent operation,” Vitale said.

The latest on the leak at Palisades Nuclear Power Plant

Palisades Nuclear Power Plant is on Lake Michigan south of South Haven.

An update on the Palisades Nuclear Power Plant.

In West Michigan, crews are continuing to try and figure out what caused the release of slightly radioactive water from the Palisades Nuclear Power Plant in southwest Michigan.

The plant was shut down a little over a week ago because of the leak, and crews say they have discovered a new crack in a water tank that's been leaking on and off for at least two years.

Detroit Mayor Dave Bing announced he will not run for re-election. What does this means for the city moving forward while currently under emergency management?

And we took a look at what's behind Michigan's high infant mortality rate.

And author, theologian, preacher, and social activist Jim Wallis joined us to talk about his book and The Common Good for America.

But first in the show, we got an update on the Palisades Nuclear Power Plant, where crews are trying to figure out what caused the release of slightly radioactive water.

'Outraged' by leak, Upton to tour Palisades Nuclear Plant

Palisades Nuclear Plant in Covert, Mich. near South Haven.

Congressman Fred Upton (MI-06) will head to southwest Michigan this afternoon, to check out the condition of the Palisades Nuclear Power Plant.

The unplanned release of slightly radioactive water into Lake Michigan earlier this month “outraged” the Republican congressman, who chairs the U.S. House’s Energy and Commerce Committee.

“Every option must be on the table to ensure that the continuing leak will not occur again,” Upton said in a statement last week, suggesting that a full replacement of the leaky water tank may be in order.

Officials from the nuclear plant maintain that the leak will not harm the public or any of the plant’s 650 workers.

A commissioner from the Nuclear Regulatory Commission will be accompanying Upton on his tour today.

The congressman is expected to speak publicly after the visit.

Michigan Radio's Lindsey Smith will be there and she'll bring us more later today.

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.
