ASME RA-S-1.4-2013

This standard sets forth the requirements for probabilistic risk assessments (PRAs) used to support risk-informed decisions for advanced non?light water reactor (non-LWR) nuclear power plants (NPPs) and prescribes a method for applying these requirements for specific applications. To support application of this standard to PRAs for a diverse set of reactor designs such as modular high-temperature gas-cooled reactors, liquid metal?cooled fast reactors, and small modular reactors, based on non-LWR technology, and other advanced non-LWRs, the requirements in this standard were developed on a reactor-technology-neutral basis.
