The Nuclear Regulatory Commission has issued a final rule and associated regulatory guide applying risk-informed, performance-based emergency preparedness (EP) requirements to small modular reactors and other new technologies (ONT).

NuScale Power and steel manufacturer Nucor have signed a memorandum of understanding to explore the deployment of NuScale’s VOYGR small modular reactor plants at Nucor’s scrap-based electric arc furnace (EAF) steel mills, the Portland, Ore.–based SMR developer announced Tuesday.

NuScale Power announced October 20 that the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) issued a letter the previous day agreeing with NRC staff’s approval of NuScale’s methodology for determining the plume exposure pathway emergency planning zone (EPZ). As approved, the methodology would permit a smaller EPZ—dependent on site-specific conditions, including seismic hazards—that provides the same level of protection to the public as the 10-mile radius EPZs used for existing U.S. nuclear power plants.

Westinghouse Electric Company has filed a pre-application regulatory engagement plan (REP) with the Nuclear Regulatory Commission for its eVinci microreactor, the company announced on Tuesday.
