*hideo ezure¹ (1. NAIS)

Keywords:dose, radioactivity, Bremsstrahlung , RPV, decommissioning

The dose rate due to the inner bremsstrahlung generated in the nuclide ⁵⁹Ni contained in BWR shroud, etc. was presented in the latest spring meeting. In this meeting the influence of the dose rate and activities of the cladding and mother material of RPV on decommissioning, the subjects concerning about neutron spectrum and impurity contain and so on will be studied and reported.
