Gamma radiation effect analysis of component for advanced spent fuel management process

For hot operation of advanced spent fuel conditioning process(ACP), the analysis of gamma radiation effect and the system design process are required to design equipment to operate reliably in a gamma radiation environment such as hot cell. To analysis the effects of radiation for ACP, we used the SCALE codes which were certified by Nuclear Regulatory Commission(NRC). The source term was calculated which reflects the features of target nuclear fuels using ORIGEN-S, a module of the SCALE code, and the gamma dose rates were calculated by using the QADS modules, considering the geometry of process equipment respectively. The result are shows that the value was maximum 3.03 Gy/h form the rod storage box in hot cell, maximum 0.6 Gy/h form the metalizer, and maximum 72.0 Gy/h form the vol-oxidizer. Considering those values, the design methods for shielding and repositioning the major equipments and components should be induced, and, the preventive maintenance for components before failure actually occurs should be minimized the effects of radiation
