Inspector discovers new water leak at Palisades nuclear plant

Lake Michigan viewed from the Palisades plant. The latest leak is from the system that uses Lake Michigan water to cool equipment. The leaking valve is in one of the secondary buildings at the location.

Documents released this week show a Nuclear Regulatory Commission inspector based at Palisades discovered the leak during a routine inspection on September 20th.  

Palisades is under more scrutiny this year after a series of problems earned it one of the worst safety ratings in the country. This is at least the third water leak (depending on exactly how you tally them) at the nuclear plant this year. You can find more details about the first leak from a large water tank above the control room here, and the second water leak from the actual reactor here.

Michigan Radio has been following the problems at the Palisades Nuclear Power Plant for the last several years.

Our West Michigan reporter, Lindsey Smith, has been on top of all the leaks, shutdowns and visits from the U.S. Nuclear Regulatory Commission.

There's been so much news of late, it can get a little confusing.

To clear up what's been happening at Michigan's oldest operating nuclear power plant, we created this timeline.

Research buoy shows offshore winds average at least 22 mph in middle of Lake Michigan

The wind buoy sits on a pier in Muskegon before it first launched back in October 2011.

Wind speed in the middle of Lake Michigan appears to be some of the best in the state for developing wind energy. That’s according to preliminary data from a high-tech research buoy that’s been anchored there all summer.

It’s pretty common knowledge that it’s windy out here off the Lake Michigan shore. But exactly how windy, and when, and what direction, details about bats and birds; none of that information has been available until now.

“I suspect that will ramp up some levels of interest in what we’re doing,” said Arn Boezaart.

Boezaart heads the Michigan Alternative and Renewable Energy Center that’s operating the buoy. He revealed the preliminary data at the center’s annual business meeting Monday afternoon.

“I think we’re demonstrating that we now have the ability to go out onto the Great Lakes and do a very credible and scientifically relevant job of measuring wind speeds, wind capacity that others can use to make whatever decisions they might,” Boezaart said.

Early data show the average offshore wind speed is at least 22 miles an hour. Wind farms have been built on land in Michigan where wind speeds average around 17 miles an hour.
