Abstract

The invention relates to a control method and system for a nuclear power plant reactor control rod availability check test. The control method comprises the following steps: judging whether a sequential control corresponding to a current test rod group on a display interface is in an unlocked state or not; if the sequential control is in the unlocking state, judging whether the sequential control is triggered or not; and if the sequential control is triggered, outputting a test signal to the rod control system according to the sequential control logic corresponding to the sequential control so as to execute the availability check test of the current test rod group. According to the technical scheme, human errors are reduced; manpower is greatly saved, and test execution efficiency is improved; the unit operation stability is improved; and the risks of overheating of the reactor core and insufficient shutdown margin in a transient state are reduced.

Description

technical field

[0001] The invention relates to the field of nuclear power, in particular to a control method and a system for a control rod availability check test of a nuclear power plant reactor. Background technique

[0002] During the operation of the nuclear power plant, it is necessary to carry out normal inspection and maintenance of the equipment to avoid accidents, including the inspection and checking test of the intact availability of the rod bundle to be used, which is used for the normal operation of the nuclear steam supply system. Check that the bundle of rods does not accidentally get stuck in the proposed position.

[0003] At present, when this test is carried out, one operator is required to perform the test operation, and another operator is required to record the test parameters generated by the test process. However, this method has the following defects:

[0004] 1. During operation and verification, the operator needs to switch the screen frequently...
