SMR-300 is unique amongst small modular reactors and large western commercial nuclear power plants. It is designed to ensure that 100% of the plant’s irradiated fuel is safely protected via passive safety systems inside its robust containment enclosure system. This protects the public and the environment from the harmful effects of radiation even in the case of the worst hypothetical accident. Conventional light water and advanced reactors store spent fuel outside of their containments, leaving those large source term systems more susceptible to exposure and release than the systems and commodities inside containments. Learning from the Fukushima disaster, Holtec includes the spent fuel pool inside containment to passively and indefinitely protect ALL of the plant’s fuel in the case of an accident.
