反应堆压力容器出口接管分析与评定

摘要

以AP1000压水堆为例，通过建立反应堆压力容器(含进、出口接管)整体模型，计算并评定压力容器出口结构在设计工况、正常、事故以及试验工况下的应力强度。为今后核电一回路反应堆压力容器分析设计奠定基础。%　　AP1000 pressurized water reactor ( PWR) is taken for example to establish an integrated model of reactor pressure vessels ( including inlet and outlet nozzles) to calculate and evaluate the stress intensity under design, normal, accident and test service conditions, which can be the foundation for the analysis and design of reactor pressure vessels in the primary circuit.
