It is important to evaluate the radioactive inventory accurately, before decommissioning of the NPP. We have improved the induced radioactivity map of TSURUGA-1, with the consideration of neutron transportation path to the detectors, in order to reduce C/M. The contribution map with adjoint neutron flux provide the useful information in this improvement process.
