摘要

为了研究缩短核电站安全壳完整性试验和泄漏率试验工期的可行性

对安全壳打压试验过程中所使用的化学品的挥发性测试结果进行了研究和分析

筛选出25种可燃性物质

在60 ℃或略高于可燃物闪点的初始温度下

对其在100、310和520 kPa的初始压力条件下的爆炸下限进行了实验研究

获得了重要的安全性实验数据。实验结果表明

对于低闪点的可燃性液体

其在不同初始压力下的爆炸下限几乎相同; 对于闪点较高的可燃性液体

当初始压力较高时

由于可燃蒸气的液化

出现不能被点燃的现象

有利于安全壳打压过程中危险性的降低; 针对11种初始压力升高后出现不可燃现象的物质

提出了一种其在所测试的初始温度下可以被点燃的最大初始压力的估算方法

可为完整性试验和泄漏率试验过程中的安全性分析提供理论依据

以缩短试验工期。

Abstract

To shorten the processing period during containment test in nuclear power plant

a feasibility study was carried out.Firstly

the volatility test results of the chemicals used during containment test were analy-ed

and 25 combustible substances were screened out.Then

the lower flammability limits of the 25 substances were tested at the temperature of 60 - or a little above their flash points

under the pressures of 100

310 and 520 kPa

respectively.The results indicate that the lower flammability limits of the liquids with low flash points are almost the same at different initial pressures.For the liquids with high flash points

there appears a phenomenon that their vapors cannot be ignited due to partial liquefaction of the combustible vapors at high pressures

which is favourable to reduction of flaming risk during containment test.Finally

for the 11 substances which will become nonflammable when the pressure reaches a certain value

a method was proposed to estimate the maximum
