Development of computer systems for planning and management of reactor decommissioning estimation of project management data on dismantling Tokai Power Station

Data on the Japan Power Demonstration Reactor dismantling activities were a nalyzed to be applied to planning and evaluation of decommissioning reactor facilities. These were then combined with the computer systems for plannin g and management of reactor decommissioning (COSMARD) as a database to esti mate decommissioning project management data such as manpower needs and rad iation exposure to workers. The Tokai Power Station decommissioning program , which will be conducted by the Japan Atomic Power Company as the first pr oject on decommissioning a commercial nuclear power plant in Japan, was cha racterized by evaluating the project management data using COSMARD and the database. It was found from the study that COSMARD and unit productivity fa ctors were applicable to planning and evaluation of reactor decommissioning programs.
