[3C09] Influence of 59Ni radioactivity on decommissioning (3)

*hideo ezure1 (1. NAIS)

Keywords:59Ni, radioactivity, dose, Bremsstrahlung, Baffle

The dose rate due to the inner bremsstrahlung by the nuclide 59Ni generated in BWR-RPV was presented in the latest autumn meeting. In this meeting the influence of the dose rate and activities of the baffle and barrel material in PWR on decommissioning, the subjects concerning about neutron spectrum and impurity contain and so on will be studied and reported.
