Abstract

This paper presents the results of the process to qualify the pressure compensator system design as a result of the reactor coolant flow thermohydrodynamic instability for the management of accidents with a complete continued loss of power supply. Exposed are the features of transonic flow regimes at two-phase flows in the pipeline valves’ flow part. Using computational modeling, the water hammer occurrence conditions have been determined for managing accidents with a continued blackout during the emergency opening of the pressure compensator safety valves due to its volume overflow. It has been found that an effective way to eliminate the water hammer emergence conditions is to increase the pressure compensator by upper part hydrodynamic resistance installing the grating structures. Based on computational modeling, functional dependencies are determined, and a method for qualifying the pressure compensator system design under accident with a complete continued loss of power supply is proposed. The conditions for ensuring the safety functions of the pressure compensator system for managing accidents with continued blacking-out shall be satisfied by maintaining the required level of reactor feed water, preventing the hydrodynamic shocks emergence, and determining the pressure compensator effective action delay of the to manage accidents.
