摘要: 启动物理试验是压水堆核电机组装料后实施的一系列堆芯物理性能试验项目。传统物理试验设备体积庞大,测量范围较小,测量精度不能满足物理试验方法要求。自主研发的启动物理试验分析系统（PSAS）针对物理试验中反应性测量方法、设备软硬件设计、微电流测量量程切换、数据处理、数据传输方式等问题进行了优化研究,以提高设备的测量能力与适用性,并减小了设备的体积。通过研究堆及阳江核电站3号机物理试验检验,PSAS可以获得准确的测量结果,适用于压水堆物理试验。

Abstract: Zero power physics test (ZPPT) is implanted after the nuclear reactor approach to criticality to make sure the core performance is in compliance with the nuclear design. However, traditional equipment used in ZPPT is bulk in volume and the measurement limit is narrow and the precision is low to adapt new test method. In the Physics Start-up Analysis System(PSAS) developed by China Nuclear Power Research Institute, the reactivity measurement method, software and hardware design, low-level current measurement range alternative, data process and transmission are optimized to enhance the measurement capability and adaptability. The test results on research reactors and Yangjiang Nuclear Power Plants unit 3 verify that PSAS is suitable for the pressurized water reactor physics test. -
