Description

technical field [0001] The invention belongs to the technical field of nuclear power plant reactor protection systems, and in particular relates to a test method, device, platform, processing terminal and computer-readable storage medium for a nuclear power plant reactor protection system board. Background technique [0002] At present, the reactor protection system RPR of the nuclear power plant receives the switching signal sent by the upstream KRG, RPN and other systems, and after logical operation, it gives protection signals such as emergency shutdown of the reactor and activation of special safety facilities. That is, the RPR system monitors the operation of the reactor in real time, and according to the change of the operating parameters, it controls the emergency shutdown of the reactor and the action of special safety facilities through its logic to prevent the state of the reactor from exceeding the specified safety limit, which is directly related to nuclear safety...
