Abstract

The invention discloses a method for monitoring radioactive substances in a nuclear power plant control room. The method comprises the following steps: acquiring activity concentration of radioactive substances in air of the nuclear power plant control room; monitoring whether the external irradiation dose and internal irradiation dose of the control room reach values which harm a human body; if so, transmitting an alarm signal. A comprehensive and reliable technology for monitoring and processing the radioactive substances in the nuclear power plant control room is realized. In addition, the invention also discloses a system for monitoring radioactive substances in the nuclear power plant control room.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a method and system for monitoring radioactive substances in a control room of a nuclear power plant. Background technique [0002] Generally, nuclear power plants are equipped with a control room for the following activities: safely operate the nuclear power plant under various working conditions; safe state of the power plant or return it to a safe state. Operators in the main control room may be exposed to overexposure in an accident due to the above activities. In order to prevent the personnel in the control room from being exposed to excessive exposure and ensure their personal safety, relevant regulations require that appropriate measures be taken and sufficient information be provided to protect the personnel in the control room. The occupational exposure of staff in any one year shall not exceed 50mSv (including external exposure and internal exposure...
