Abstract

Abstract

Accident response characteristics of the passive safety system and the parameter variation of the primary loop system were obtained through the experimental study of double-ended break of modular small reactor pressurizer surge line . The results show that under the extreme condition of double-ended break of the pressurizer surge line, the MP accumulator can provide a large stable safety injection flow in a short time to replenish the water capacity of the system in time; The operation process of the HP safety injection system is relatively complex, and the safety injection flow rate is closely related to the medium state of the pressure balance pipeline of the core makeup tank and the operation state of the MP safety injection system, and it is in the state of intermittent injection within 1.7 hours. During the whole accident process, the core has been submerged. The modular small reactor passive safety system can ensure the core safety under the extreme condition of double-ended break of pressurizer surge line.
