COMPARATIVE ANALYSIS OF NUCLEAR SAFETY OF REGULAR AND COMPACT SPENT FUEL STORAGE ON CHORNOBYL NPP
17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))
PHYSICAL PROBLEM OF SPENT FUEL, DECOMMISSIONING AND RADWASTE
Spent fuel wet storage facility ISF-1 is currently used for intermediate storage of spent nuclear fuel removed from Chornobyl-1, 2 and 3.
Since commissioning of the ISF-2 dry spent fuel storage facility is significantly delayed, ISF-1 is going to be used as the main spent fuel storage facility for the Chornobyl NPP in the next few years. As ISF-1 is not capable of accommodating all SFA from ChNPP with use of the regular (design) storage scheme, compact storage of nuclear fuel in ISF-1 is under consideration.
The paper presents a comparative criticality safety analysis of regular and compact spent fuel storage in ISF-1 in operational and emergency conditions.
