NRC reorganization update: Changes will begin this summer
The Nuclear Regulatory Commission is moving forward with its plans to reorganize around three core business lines: new reactors, operating reactors, and nuclear materials and waste. In order to do that, the agency will establish two new offices: the Office of Advanced Reactors (OAR) and the Office of the Chief Nuclear Reactor Inspector (CNRI).
