Assessment of the design of injection and depressurization system dedicated for severe accidents for VVER440
Original language description
Severe accident mitigation measures are gradually implemented at Slovak nuclear power plants. Coolant injection, into primary circuit and depressurization system of primary circuit were included within the scope of measures to cope with severe accidents. One of the crucial issues of these systems is to ensure successful quenching of the core during water delivery in severe accident conditions. System is designed to deliver water into primary circuit, spent fuel pool and also to containment spray system. Water delivery into primary circuit, capable of quenching the core, has to be considered in connection with design of the primary circuit depressurization system for severe accident conditions in order to maintain such low pressure in primary circuit that is necessary to keep required water flow into primary circuit. Conservative approach was used for design of both (depressurization system and system for water delivery into primary circuit), but best estimate analyses were executed to prove their inte
