To develop the decommissioning scenario of KARTINI TRIGA Reactor, the flux distribution and the radioactive concentration were calculated using PHITs and DCHAIN-SP. The radioactive waste category of each reactor component was determined based on its time-dependent radioactive concentration distribution. This information was applied to decide the waste management options such as disposal, storage, and clearance.
