Longtime nuclear industry executive Chris Mudrick has been named the new chief nuclear officer at Constellation Energy, effective September 29. He will take over the position from Dave Rhoades, who is retiring from the role.

History: Mudrick has been Constellation’s senior vice president of generation growth since December 2024, a position that marked his return to the company after serving as executive vice president and CNO at Bruce Power in Ontario, Canada, for more than four years. Prior to joining Bruce Power, Mudrick was at Constellation/Exelon for more than 32 years, ending his time there as senior vice president of operations–East and chief operating officer. He began his career with the company as a nuclear power plant operator in Pennsylvania in 1987.

Exelon Generation announced yesterday that it is investing more than $300 million in capital projects at its Byron and Dresden nuclear plants in Illinois over the next five years and filling some 650 vacant positions across the state.

These actions are in response to Illinois Gov. J.B. Pritzker’s recent signing of S.B. 2408, the hard-won legislation that rescued the nuclear facilities from premature retirement.

Exelon Generation has received a grant from the Department of Energy to explore the potential benefits of on-site hydrogen production and has chosen its Nine Mile Point nuclear power plant as the demonstration site, the company announced on Wednesday. (In 2019, Exelon received a conditional commitment from the DOE to co-fund a hydrogen electrolyzer demonstration at a nuclear plant.) Located in Scriba, N.Y., Nine Mile Point consists of two boiling water reactors—the 620-MWe Unit 1 and the 1,287-MWe Unit 2.
