Substantiation Сonstruction of the pressure compensator system of Blackout Accident Management Strategies of Power Plants

EasyChair Preprint no. 2720

Abstract

Developing effective accident management strategies with complete loss of long-term power supply at nuclear power plants requires the qualification of existing and promising passive safety systems that do not require power supply. One of the approaches to solving this problem is to qualify the system of pressure compensator for accidents with complete loss of long-term power supply. The original method of qualification of the system of pressure compensator for the conditions of accidents with complete loss of long-term power supply is presented, taking into account the significant dynamics of thermo-hydraulic processes in the reactor. As a result of the computational modeling of the developed method of qualification of the pressure compensator system for the conditions of failure with complete loss of long power supply, it is established that the effective action of the pressure compensator system to maintain the required level of coolant in the reactor is carried out up to 900 s from the beginning of the emergency process.
