The Analysis for the Reason of Containment Spray Pump Test's Unloading Time and the of Application and Optimization of GPS
The computer system of PWR nuclear power plant,responsible for each data acquisition system and sent to the main control room,an important function of monitoring equipment on the spot.The high precision time display as important reference for periodic testing of nuclear safety related equipment,often become test qualified or not key.For example during performance test low load operation to perform emergency diesel gen-erators,repeated EAS pump(containment spray pump)test unloading time in poor condition,leading to the unqualified test results.This paper tries to analyze the 3,4 of unit two Qin factory nuclear power plant data ac-quisition computer supervision system,find out the root cause of EAS pump unloading time test unqualified,and develop solutions,finally through analysis and verification,the scheme is reasonable and feasible.
