Small Modular Reactor Staffing and Current Regulation

Abstract

SMR designs currently under development are expected to experience lower probability of core damage and radioactive release than current reactors. The lower anticipated risk is attributed to a smaller core, simpler design (less complex systems), and a focus on passive rather than active safety systems. These characteristics may enable SMRs to operate with a smaller staffing complement than traditional reactors. Updated regulatory guidance is needed to support SMR licence applications that are proposing further reductions in on-site staffing or complete remote operation.
