A new report finds nuclear power plants in this region will face heat stress in the future because of climate change.

Moody’s Investors Service found the nuclear power plants in Michigan and the nearby Davis-Besse plant in Ohio fall into the High Risk category. The analysis says that means the nuclear power plants will face relatively high changes in temperature extremes compared to the global average.

David Kamran is one of Moody’s analysts.

“As these entities, the plants, want to have their licenses extended over many years, they may need to make additional investments to keep up with new information regarding climate and temperature and water, that sort of thing,” said Kamran.

The nuclear power plants use massive amounts of water. While the supply is not an issue, the temperature of the water could be an issue in the future depending on how fast the climate changes.
