Abstract

The invention is applicable to the technical field of reactor control and protection systems and provides a detector test device for a nuclear instrumentation system of a pressurized water reactor nuclear power plant. The device comprises a first power supply, a signal conditioning circuit and a signal processing circuit. The first power supply supplies power to the signal conditioning circuit andthe signal processing circuit. The signal conditioning circuit comprises a pulse adjustment circuit, a current amplification circuit and a positive / negative high voltage module. The signal processingcircuit performs operation processing on an amplified signal outputted by the signal conditioning circuit and outputs test data. Through the device, the off-line verification and copying of an RPN system detector can be realized, detector spare parts can be verified in advance, and the reliability of the detector quality is confirmed.

Description

technical field [0001] The invention belongs to the technical field of reactor control and protection systems, in particular to a detector test device for a nuclear instrument system of a pressurized water reactor nuclear power plant. Background technique [0002] With the development of nuclear power, the number of detectors used in the nuclear instrument RPN system of multi-base power plants has increased significantly, but the quality of the detectors currently depends on the quality report of the manufacturer and the neutron source test based on the site; when the RPN system detectors are applied to the site When a fault occurs, it will cause abnormal fluctuations in the signal or cause the unit to return to the state for processing. The detector equipment used in the RPN system is a strategic spare part of the nuclear power plant and has a long storage period. The existing technology cannot satisfy the early identification of the defects of the RPN system detector and t...
