SYSTEMS-ENGINEERING FOR DECOMMISSIONING THE JAPAN POWER DEMONSTRATIONREACTOR

The Japan Power Demonstration Reactor (JPDR) decommissioning program i s in progress: new technology for reactor decommissioning is being dev eloped and a database is being established. Various data pertaining to dismantling of the JPDR have been accumulated in the database. The da ta collected in the program are being used for (1) managing ongoing di smantling activities, (2) verifying the code system for management of reactor decommissioning (COSMARD) developed for the forecasting of man agement information, and (3) planning future decommissioning of commer cial nuclear power reactors. COSMARD and the database are expected to be particularly useful in the last of these three.
