[2C14] Influence of 59Ni radioactivity on decommissioning

*hideo ezure1 (1. Nippon Advanced Information Service Company, Inc.)

Keywords:bremsstrahlung, 59Ni, radioactivity, dose, decommissioning

A large quantity of SUS is used in nuclear power reactors. While they are being operated, much radioactivity of 59Ni is produced. Calculating the dose due to its inner bremsstrahlung together with ones of others radioactive nuclides, it is discussed how far the influent of these result extends for decommissioning plan. This is a revised text of 1C04 reported in 2016 autumn meeting.
