The method for evaluating efficiently decommissioning cost in a short time was made based on the features of various types of nuclear facilities where the feature of nuclear facilities was arranged. The evaluation method can calculate decommissioning cost using conversion factors corresponding to weight of components and structures of nuclear facilities, etc. The conversion factors were made based on the experience of the JPDR decommissioning projects in the Japan Atomic Energy Research Institute (JAERI) and of improvements of the reprocessing plant of the Japan Nuclear Cycle Development Institute (JNC). In this report, the decommissioning cost evaluation method of nuclear facilities that had been made before unification of JAERI and JNC was revaluated as a new decommissioning cost evaluation method to reasonably advance decommissioning plans of various nuclear facilities.
