RADIATION SAFETY EVALUATION OF THE HANARO RESEARCH REACTOR SPENT FUEL DISPOSAL SYSTEM

초록

HANARO is a multi-purpose Korean research reactor with a high neutron flux and unique fuel types. Recently, a new conceptual disposal system for HANARO spent fuel has been suggested as a solution to the current spent fuel accumulation problem in the near future. This paper investigates HANARO spent fuel characteristics, evaluates radiation intensity by generating its own cross-section library and, finally, estimates the radiation safety of its disposal system. By comparing the absorbed dose of the engineering barrier with the recommended value, it was concluded that the proposed disposal system has a large enough safety margin.
