Development of Approaches, Methodologies and Criteria for Determining the Technical Basis for Emergency Planning Zone for Small Modular Reactor Deployment

Small Modular Reactors (SMRs), with electrical power up to 300 MW per module, have?specific design, safety and siting features as well as applications?that should be properly assessed to formulate and plan for adequate Emergency Preparedness and Response (EPR) arrangements, in particular the size of Emergency Planning Zones (EPZs). EPR is one of the elements in the development of a national infrastructure for nuclear power, while EPZ is one of?the specific regulatory aspects to enable SMR deployment in diverse siting niches. The CRP has the key objective to develop approaches and methodologies which enable relating design and safety features of SMRs with the extent of offsite arrangements needed, focusing on the size of EPZ, by comparing design- and site-specific technical basis to be provided by SMR developers, nuclear regulators, emergency planners and users/utilities;?Notes: An EPZ consists of?the precautionary action zone (PAZ) and the urgent protective actions planning zone (UPZ) where arrangements have been made to take precautionary and urgent protective actions in the event of a nuclear or radiological emergency to avoid or minimize severe deterministic effects off the site and to avert doses off the site in accordance with international safety standards.
