The ISF-2 Project is part of the Chernobyl NPP Decommissioning Program. The initial design of ISF-2 was developed by Framatome (France) using the technology of "dry" storage for spent fuel assemblies from reactors RBMK-1000. The ISF-2 design was finalized by JSC KIEP in cooperation with Holtec International, USA.
ISF-2 provides for preparation of 2500 fuel assemblies for storage per year and placement of more than 21,000 fuel assemblies for long-term storage. The technical solutions developed for ISF-2 assume deployment of a passive system for heat removal from spent nuclear fuel accommodated in the double-wall shielded canisters inside the concrete modules which exclude any interaction with the environment and ensure a complete resistance to any extreme natural and man-induced impacts. The lifetime of ISF-2 is 100 years. The storage facility is located within Chernobyl Nuclear Power Plant area.
