Optimization of Gas Flow Field During Pressure Relief Process of Containment Pressure Test
As a mandatory test in the first major overhaul of a nuclear power plant and must be conducted every ten years,containment pressure test verifies the ability of the containment structure to withstand design basis accidents.The pres-sure relief process is a key part in the containment pressure test.This work studies the gas flow field inside the contain-ment during the pressure relief process,including mathematical modeling and quantitative analysis of pressure field,ve-locity field,temperature field,etc.,aiming to improve the pressure relief rate of the containment pressure test and pro-vide effective guidance for optimizing the containment pressure test.
