Abstract

The invention provides a radiation protection expert system for a nuclear power plant. The system includes a nuclear power plant radiation monitoring and early warning module, used to display radiation monitoring data generated by a radiation monitoring system data module and radiation monitoring data generated by a gamma camera radiation monitoring data module in a three-dimensional simulation model of the nuclear power plant. The system also provides a visual three-dimensional radiation monitoring interface. An alarm signal is sent when radiation dose level of a monitored position exceeds awarning value, and the three-dimensional radiation monitoring interface is positioned to an alarm area. The system can realize radiation monitoring of a nuclear power plant, full digitalization of radiation protection design, and three-dimensional visual radiation monitoring of the nuclear power plant.

Description

technical field

[0001] The invention relates to the field of radiation protection of nuclear power plants, in particular to an expert system for radiation protection of nuclear power plants. Background technique

[0002] In the nuclear energy system, nuclear fission reactions will produce various radioactive substances. With the increase of the operating time of the nuclear power unit, these radioactive substances gradually accumulate in the pipeline, forming radioactive hot spots, causing the staff to be in maintenance, inspection and process Increase in occupational exposure doses. During the entire life cycle of a nuclear power plant, radiation protection of the staff is required to control the collective dose caused by occupational exposure. Collective dose control not only reflects the level of nuclear power plant operation, maintenance and safety management, but also one of the comprehensive indexes of nuclear power plant WANO (World Association of Nuclear Operators) ...
