Constellation appoints new nuclear chief
Rhoades
Mudrick
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.

Irradiation of polymer-based directional dry adhesives with gamma photons has been performed. This irradiation is commensurate with the radiation that an adhesive sample would be exposed to if deployed in a nuclear glove box or other high-radiation environment. Before and after irradiation, samples were tested using a three-axis adhesive testing stage and were analyzed via a scanning electron microscope and a water droplet contact angle analyzer. At doses in excess of 270 kGy, the adhesive performance began to deteriorate, continuing to an overall performance reduction of 55% at a dose of [approximately]500 kGy. Significant changes in the surface energy of the bulk polymer are also indicated by changes in water droplet contact angles, contributing to the adhesion performance loss. Such analyses allow for quantitative statements to be made about the expected performance of these adhesives when deployed in high-radiation environments.
