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.

Generation IV high-temperature-reactor (HTR) systems use closed gas Brayton cycles to realize high thermal efficiency in the range of from 40% to 50% or more. The waste heat is removed through coolers by water at a substantially greater average temperature than in conventional condensing Rankine steam cycles. This paper introduces an innovative advanced multieffect distillation (AMED) design that can enable the production of substantial quantities of low-cost desalinated water using waste heat from closed gas Brayton cycles. A reference AMED design configuration, optimization models, and simplified economics analysis are presented. By using an AMED distillation system, one can fully utilize the waste heat from closed gas Brayton cycles to desalinate brackish water and seawater without affecting the cycle thermal efficiency. Analysis shows that cogeneration of electricity and desalinated water can increase net revenues for several Brayton cycles while generating large quantities of potable water. AMED combined with closed gas Brayton cycles could significantly improve the sustainability and economics of Generation IV HTRs.
