三代核电设备鉴定用浸没试验系统的设计与验证

Design and Verification of Submergence Test System for Qualification of Third-generation Nuclear Power Equipment

为了验证三代核电厂核级设备在浸没条件下的功能特性,通过分析浸没试验要求曲线及影响试验效果的关键问题,设计了1套浸没试验系统,并对该系统进行调试。结果表明:调试后系统得到的试验曲线与试验要求曲线吻合,该浸没试验系统满足核级设备鉴定的需要,可模拟设备在核电厂发生事故后的浸没状态。

In order to verify the functional characteristics of the nuclear grade equipment in the third generation nuclear power plant under immersion conditions,a set of immersion test system was designed and debugged by analyzing the required curve of immersion test and the key problems affecting the test results.Results show that the test curve obtained by the debugging system is consistent with the required test curve.The immersion test system can meet the needs of nuclear grade equipment identification and simulate the immersion state of equipment after an accident in a nuclear power plant.
