安全壳整体试验标准ANSI/ANS-56.8-1994在田湾核电厂的应用

Application of Containment Leakage Test Code ANSI/ANS56.8-1994 in Tianwan Nuclear Power Station

为有效测量反应堆安全壳整体试验的泄漏率,田湾核电厂依据美国安全壳整体试验标准ANSI/ANS-56.8-1994开发了一系列完整的泄漏率计算程序,并先后在田湾核电厂1/2#机组首次在役整体试验中应用,效果显著。本文介绍了ANSI/ANS-56.8-1994标准在试验中的数据处理过程,以期能提供给国内核电厂安全壳整体试验以借鉴。

For measuring the containment integrated leakage rate effectively,a series of calculation program was developed according to American national standard for containment system leakage test requirements ANSI/ANS-56.8-1994 by Tianwan Nuclear Power Station（TNPS）,and this computing program was applied well in the containment system leakage tests for Unit 1 and Unit 2 of TNPS.The detailed calculation process is introduced by this paper to give an example in other containments integrated leakage tests.
