[3M_PL] Graded Approach for Research Reactors

[3M_PL03] Current status of Graded Approach Regulations for Research Reactors

*Takumi Koyamada¹ (1. NRA)

Many nuclear experts know small risks of research reactors in comparison with those of commercial power reactors, and are, typically, not familiar with the current state of Japanese regulations. To ensure effective regulatory control of different facilities, it is necessary to apply a graded approach in a way that the degree of implementation of regulatory requirements corresponds to the associated radiation risk. In this session, we will review the current Japanese regulations in view of the graded approach to identify issues required for effective and efficient regulations.
