Keywords:decommissioning, Fugen, Sampling, radioactivity inventory, radionuclide analysis

The reactor of Fugen has high radioactivity level and is planed to be dismantled in water remotely to reduce the exposure. Because the radioactivity inventory of reactor affects the specifications of the dismantling water pool and the manufacture of the disposal body, it is essential to improve the accuracy of the radioactivity inventory of it. In this presentation, the package plan from sampling of reactor core components to radionuclide analysis is announced.
