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.
