Discussion of Issues for Small Modular Reactor PSA

Small module reactors (SMRs) are in ascendant in the world due to their shorter design & construction duration and higher safety level. Probabilistic safety assessment (PSA) will play an irreplaceable role in small module reactor design demonstration and other application stages. A mature PSA methodology framework is mature and has successfully used in commercial nuclear power plant application. While several issues are worthy of discussion when PSA performed for SMRs project. Based on traditional PSA framework and its fundamental elements, potential technical issues put forward for discussion for SMRs project PSA, which will provide references for the combination of PSA and SMRs project.
