Bowen to lead new Office of Advanced Reactors
Jeremy Bowen will head the newly created Office of Advanced Reactors when it launches in September, the Nuclear Regulatory Commission announced Monday.
This new office will license and oversee new and advanced reactors. In his role, Bowen will be responsible for the review of advanced reactor applications—reviews that the NRC said will be “expeditious.”
