摘要

近年来，国内外进行多项研究堆概率安全分析，其中管道破口导致的失水事故是堆芯损坏的重要风险来源。本文参考管道破口计算程序PRAISE（Piping Reliability Analysis Including Seismic Events）方法，选取压力壳型研究堆——高通量工程试验堆（High Flux Engineering Test Reactor，HFETR）的运行工况，对其反应堆冷却剂出口管道的焊缝进行分析，得到运行中该处焊缝发生各类破口的频率。

Abstract

Background

In recent years

a number of probabilistic safety analysis for research reactors have been carried out

in which loss-of-coolant accidents due to pipe break are important.

Purpose

The aim is to calculate the break frequency of a weld of the reactor outlet pipe of the high flux engineering test reactor (HFETR).

Methods

This study referred to the algorithm of piping reliability analysis including seismic events (PRAISE) computer code

selected the operating condition of a tank-type research reactor-HFETR.

Results

A weld joint of the reactor coolant outlet pipe was calculated. And the frequencies of all kinds of leaks at the weld joint were obtained.

Conclusion

By doing ultrasonic examination before the operation

the frequency of pipe break can be effectively reduced.
