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 purpose of the invention, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0041] Please see figure 1 as shown, figure 1 A nuclear power plant radiation alarm suppression method is provided, specifically including:

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

[0043] The radiation monitoring system of the nuclear power plant monitors the gamma dose rate and neutron dose rate in the relevant areas of the control area through two monitoring methods to avoid hig...

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 security field of nuclear power plants, and more specifically, the invention relates to a radiation alarm suppression method, equipment and system for nuclear power plants. Background technique [0002] The main function of the plant radiation monitoring system (Plant Radiation Monitoring System, KRT) is to realize the radiation monitoring of safety barriers, effluents, and workplaces in the nuclear power plant, provide an alarm function, and take necessary measures in a timely manner. The alarm signal is sent to the digital control system of the nuclear power plant (Digital Control System, DCS) displays or / and interlocks the equipment of the process system in the main control room. According to the design situation of the current radiation monitoring system, the radiation monitoring equipment is generally designed to automatically trigger a fault alarm and an over-threshold alarm after power failure to achieve fail safety....
