Palisades nuclear power plant shuts down to fix water leak

The Palisades Nuclear Power Plant near South Haven has an aluminum water tank that’s used in case of emergencies or when the plant needs to be refueled.  That water tank has been leaking for several weeks.  On Tuesday evening, the Palisades plant was shut down so workers can fix the leak.

The shutdown this week was a planned outage – so, in other words, the plant operators saw this coming.

Mark Savage is a spokesperson for Entergy, the company that owns the Palisades plant.  He says this tank has been leaking for several weeks. It’s an old aluminum tank that holds 300,000 gallons of water.  He says the tank is the same age as the Palisades plant: 40 years old.

It’s considered to be a small leak and the company has been collecting the water and monitoring it for weeks.  But on Tuesday the amount reached 31 gallons per day... and that was the threshold where the company determined the leak had to be fixed. So that means taking the plant out of service.

The federal Nuclear Regulatory Commission is in charge of oversight on the country's nuclear power plants. NRC spokesperson Viktoria Mitlyng says the water leaking out of the tank does not pose any safety hazard.

"They’re collecting that water; it has no way of getting out of the plant. It cannot go outside and it does not pose a threat to plant workers and at this rate of leakage it does not compromise the plant’s stability or safety."

Entergy's Mark Savage declined to say how long the outage will last.  But he says the procedure is pretty straightforward:

"Shut the reactor down - which we’ve done, unload the water from the tank, find the leak, repair the leak, fill it up again and start the reactor back up."

This time around the shutdown was planned.  But Palisades had five unplanned shutdowns last year – and one of those was considered to be of substantial safety significance.  Because of that the power plant now has one of the worst safety ratings in the country, and that means the federal government is watching the plant more closely. NRC spokesperson Viktoria Mitlyng says they want to see how the plant operators handle this repair... and find out what caused the leak in the first place.

NRC Chairman: Palisades needs to work on “the basics of nuclear safety”

The head of the U.S. Nuclear Regulatory Commission says operators of the Palisades Nuclear Power Plant must improve plant safety.

NRC Chairman Gregory Jaczko shared his thoughts following a three-hour tour of the plant in South Haven Friday.

“There’s really a need to improve on fundamentals. Just some of the basics of nuclear safety really need to be worked on,” Jaczko said. “We’re starting to see some of that happen which is a positive but it needs to be sustained to ultimately get the performance where we’d like to see it."

Palisades offline...this time for planned shutdown to refuel

Workers were already preparing for the planned outage in late March. More than 1,000 extra workers are on site for the shutdown.
Mark Savage Entergy Nuclear Operations

Workers have shut down the Palisades Nuclear Power Plant in South Haven to refuel.

Palisades had five unplanned shutdowns in 2011. The Nuclear Regulatory Commission downgraded the plant’s safety rating because of a series of problems – including one “significant” issue when the plant’s control room lost half its indicators. The power plant now has one of the worst safety ratings in the country.

There are more inspectors on site because of the planned outage, but they will not be addressing last year’s safety problems at this time.

“(The NRC) can only conduct those inspections after the company tells us 'we have done the work that we need to do to fix the issues that we have,” said NRC spokeswoman Viktoria Mytling.

Nuclear watchdog goes after operators of Palisades plant

NRC.gov

A nuclear watchdog group is asking the Nuclear Regulatory Commission to take stronger enforcement actions against the Palisades Nuclear Plant in South Haven.

The Nuclear Regulatory Commission will increase scrutiny at the plant because of a downgrade in its safety performance rating.

But Thomas Saporito says that’s not good enough. “I think the conduct by the NRC is outrageous. I think the NRC misrepresented to the public that the plant is being operated safely. It most certainly is not operating safely,” Saporito said.

Regulators work to reassure people near Palisades nuclear plant

Officials from the Nuclear Regulatory Commission answered questions about safety violations at the Palisades Nuclear Power Plant Wednesday night. About 150 people attended the meeting in person, while others listened in over the phone.

Officials with the Nuclear Regulatory Commission were trying to ease the community’s concerns after 5 unplanned shutdowns last year (4 we’re reactor shutdowns).

But like many residents who spoke out at the meeting, Maynard Kaufman said he won’t feel better unless the plant is shutdown. Kaufman lives on a farm just ten miles away from Palisades.

“I don’t know why we’d take chances with the wonderful agricultural area downwind from this plant in Van Buren and Kalamazoo Counties. It would be a shame to wreck that. And it could happen,” Kaufman warned.

Nuclear Regulatory Commission to answer questions about Palisades

This Wednesday the Nuclear Regulatory Commission will hold a public meeting to discuss safety violations at the Palisades Nuclear Power Plant in South Haven.

The plant had five unplanned shutdowns last year. As a result, the NRC downgraded the plant’s safety performance rating. Now it’s one of only four plants in the country with such a bad safety rating.

Michigan's Palisades nuclear power plant downgraded over safety concerns

The Palisades nuclear power plant near South Haven, Michigan has been listed as one of the nation's poorest performing in terms of safety violations, according to the Nuclear Regulatrory Commission.

More from the Associated Press:

COVERT TOWNSHIP, Mich. (AP) - The Nuclear Regulatory Commission has downgraded the Palisades nuclear power plant in southwestern Michigan following an investigation of two incidents last year that
raised safety concerns.

The NRC notified the plant Tuesday of its decision.

The agency groups nuclear plants into one of five regulatory columns depending on their performance, with the fifth category being the worst. Palisades was bumped from the second to the third column.

The Kalamazoo Gazette reports that Palisades is one of only four plants in the nation in either the third or fourth columns.

None are in the fifth.

Palisades spokesman Mark Savage tells The Associated Press the violations that caused the NRC investigation involved equipment or maintenance.

He says the plant is operating safely.

Palisades is owned by New Orleans-based Entergy Corp.

Blown bulb behind Palisades shutdown

NRC

How many nuclear power plant employees does it take to screw in a light bulb? Evidently more than were on hand last September at the Palisades Nuclear Power Plant in western Michigan. According to a report from the Detroit Free Press, an unplanned reactor shutdown at Palisades last fall can be attributed to a plant worker improperly replacing a light bulb.

From the Freep:

Palisades acknowledges mistakes; insists less risk than regulators think

Officials from Entergy Corporation, the company that operates the Palisades Nuclear Power Plant near South Haven, appeared in front of the U.S. Nuclear Regulatory Commission on Wednesday.

The company is hoping to avoid getting another safety violation; it was issued one already this month. “We’ve lost the trust of our neighbors. We’ve lost the trust of our corporation and we’re going to fix that,” said David Hamilton, general manager of plant operations. The hearing was about two separate incidents at the plant last year.

Entergy Corporation “concurs” with NRC’s findings

The more serious of the two incidents was a week-long shutdown of the power plant last September. It went offline because of an electrical outage at the plant that happened because a worker didn’t follow proper procedures during routine maintenance.  “This was an event that allowed my electricians to feel that they could put themselves at such risk; I apologize if I get emotional but I could’ve killed somebody on the weekend of September 25th,” Hamilton said.

A team of experts from the Nuclear Regulatory Commission is inspecting the Palisades Nuclear Power Plant in southwest Michigan. There are no safety concerns and everything is now working properly at the plant.

Last week, a coupling that attaches to a water pump failed. The water pump is one of three at the plant that cool safety equipment. The part was replaced and the pump is back in service. The same water pump had a coupling fail in 2009.
