OAK HARBOR, Ohio (AP) - Operators of a northern Ohio nuclear plant that sits along Lake Erie say workers there found a gap within the concrete of a protective wall.

Officials at the Davis-Besse nuclear plant near Toledo describe the gap as an air pocket and say they don't believe it affected the structural integrity of the shield wall.

The gap was discovered Thursday while the plant was shut down to replace two steam generators.

The University of Michigan is almost finished decommissioning its nuclear reactor. The process began ten years ago. But there are new plans in the works to renovate the building.

According to MLive, the University wants to create research labs, testing areas, offices and academic support spaces in the building. The 17,400-square-foot building would get a 5,200-square-foot addition and would be renamed as the Nuclear Engineering Laboratories. It's on North Campus on Bonisteel Dr. 

The University of Michigan Board of Regents will vote on the proposed plans at 3 pm on Thursday.

It’ll take months to determine any violations stemming from radioactive leak at Palisades

The tank that was fixed is only used during refueling outages and in cases of emergencies.
Mark Savage Entergy

Federal nuclear regulators say it’ll be several weeks before they can determine if Entergy, the company that owns the Palisades Nuclear Plant, violated any regulations during an incident in May when 80 gallons of slightly radioactive water leaked into Lake Michigan.

Related: Read this for a brief summary of all the problems at Palisades

The leak happened in May. Regulators say there was no threat to public safety, and the leak is now fixed.

When workers fixed the leaky tank they discovered the sand bed that was supposed to be supporting the tank was never installed. Palisades was built in 1968.

“If the causes (of there being no sand bed) were so long ago and it’s not indicative of recent performance then it’s assessed a little bit differently,” Jack Giessner said during a public forum held online Tuesday afternoon. Giessner is branch chief at the Nuclear Regulatory Commission.

“It still may have some follow up needed but in general, it’s not like we’re going to try to interview people from 1968,” Giessner said.

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.

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

Lindsey Smith Michigan Radio

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

A slide from the online meeting NRC hosted Tuesday.
Nuclear Regulatory Commission

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.

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.
