AP1000主回路系统热工水力瞬态计算程序RETAC的开发
Development of Thermal-Hydraulic Transient Analysis Code RETAC for AP1000 Primary Loop
摘要
Abstract
A thermal-hydraulic microcomputer code (RETAC, Reactor Transient Analysis Code) for transient analysis of AP1000 primary loop was developed using FORTRAN language. The loss of flow accident (LOFA) was analyzed using RET AC. Transient characteristics of some main system parameters were obtained, including the maximum fuel temperature and MDNBR in the hot channel, pressure and water level in the pressurizer and steam generator secondary side. The results show that at the early stage of the loss of flow accident, the highest fuel central temperature and MDNBR in the hot channel do not exceed specified limits and meet the safety criteria. Modular programming technique was adopted for RET AC and it is convenient for further modification andapplication. It is expected that the present work is instructive to develop Chinese ownindependent software for the design and safety analysis of large scale PWR.关键词
