Abstract

Abstract

In order to analyze the hydrodynamic loading characteristics caused by coolant jetting and pressure relief wave propagating in the reactor primary system of the nuclear power plant during a hypothetical fracture of the reactor primary system, HLPS, a software to calculate the hydraulic load in the loss of coolant accident (LOCA) in PWR primary circuit, is developed on self-reliance using C++ programming language. Taking M310 reactors coolant as the object, the results of HLPS software are compared with engineering data. The results show that the calculated results of HLPS software are in good agreement with engineering data, at the same time, HLPS adopts implicit solution and higher convergence standard, and the result is more accurate. It can be used for the analysis of the primary circuit system coolant loss accident.
