24 commercial nuclear power plants become the decommissioning in Japan, and the process are carried out. The decommissioning is necessary the classification disposal based on the level division of the radioactive waste. In addition to the nuclear reactor, a reactor container vessel, equipment components and a reactor building are performed the evaluation of radioactivation. Because there is a difference for each power plant, an individual evaluation is required for the reactor and the building. We develop a standard model to execute the radioactivation calculation used the neutron transport calculation in consideration of an individual difference.
