Problems of Ranging of Radioactive Waste Storage and Disposal Objects and Their Solution Using a Database

The database "Objects for Storage and Disposal of Radioactive Wastes from Nuclear Fuel Cycle Enterprises" has been developed. Criteria were chosen for assessment of the hazard of storage and disposal (SD) objects for staff and population, and parameters based on these criteria were suggested: local hazard parameter and geospheric hazard parameter. To calculate the latter parameter, it is recommended to use simple models of radionuclide egress into the geosphere. The database can be used as an effective tool for ranging of SD objects of nuclear fuel cycle (NFC) enterprises in the order of decreasing hazard parameters. The use of a procedure for ranging of SD objects, tested with one of NFC enterprises as example, makes it possible to reveal the most hazardous SD objects at NFC enterprises and to decide on priority in decommissioning.
