Problems solved by technology

Since the relay alarm signal suppression needs to be operated by the staff on the spot, the staff needs to enter the site and disconnect the suppression switch in the junction box, so that the DCS signal input is forced to a low level to realize the alarm suppression, so that the staff must stay in the radiation place to realize The operation increases the staff's stay time in the radiation place, exposes the staff to the radiation place, affects their physical and mental health, and is not conducive to reducing the exposure dose

Embodiment Construction

[0040] In order to make the invention purpose, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for explaining the present invention, rather than for limiting the present invention.

[0041] see figure 1 shown, figure 1 Provided is a nuclear power plant radiation alarm suppression method, which specifically includes:

[0042] Step 101, the nuclear power plant radiation monitoring system sends monitoring result information to the nuclear power plant digital control system DCS.

[0043] The radiation monitoring system of the nuclear power plant uses two monitoring methods to monitor the gamma dose rate and neutron dose rate in the relevant areas of the control area, so as to avoid high-dose exposure of workers: use...

Abstract

The invention discloses a nuclear power station radiation alarm inhibition method comprising the steps that a nuclear power station radiation monitoring system transmits monitoring result information to a nuclear power station digital control system DCS; if the monitoring result information is early warning information, whether alarm operation is executed is confirmed by the DCS according to the preset alarm control state; and if the alarm control state is an alarm inhibition state, execution of alarm operation according to the early warning information is forbidden by the DCS. Therefore, remote alarm inhibition in a nuclear power station can be realized. Besides, the invention also discloses a nuclear power station radiation alarm inhibition device and system.

Description

technical field [0001] The invention belongs to the field of nuclear power plant security, and more particularly, the invention relates to a radiation alarm suppression method, equipment and system for a nuclear power plant. Background technique [0002] The main function of the nuclear power plant radiation monitoring system (Plant Radiation Monitoring System, KRT) is to realize the radiation monitoring of the safety barrier, effluent, and workplace in the nuclear power plant, provide an alarm function, take necessary measures in a timely manner, and send the alarm signal to the nuclear power plant digital control system. (Digital Control System, DCS) The equipment that displays or / and interlocks the control process system in the main control room. According to the design of the current radiation monitoring system, radiation monitoring equipment is generally designed to automatically trigger fault alarms and over-threshold alarms after power failure to achieve failsafe. Wh...
