Abstract

The invention relates to a digital nuclear facility environmental radiation monitoring system. The digital nuclear facility environmental radiation monitoring system comprises a control device and field measuring devices. The control device comprises a central station. The field measuring devices include an environmental medium sampler, a meteorological sensor and a radiation detector. The radiation detector is a digital NaI (TI) spectrometer internally provided with a high-range dosage rate detector. The environmental medium sampler, the meteorological sensor and the digital NaI (TI) spectrometer are connected with a local industrial computer, measuring signals and sampling signals are transmitted to the local industrial computer which is connected with the central station in a wired communication mode and in a wireless communication mode, and the central station remotely monitors the working state of all the field measuring devices. According to the system, nuclide recognition can be carried out while a radiation dose rate gamma is given, communication is reliable, the bandwidth is high, interference is not likely to happen, and the data acquiring rate of the system can be guaranteed.

Description

Technical field

[0001] The invention belongs to the technical field of nuclear radiation measuring instruments and automatic control, and specifically relates to a digital nuclear facility environmental radiation monitoring system. Background technique

[0002] The environmental radiation monitoring system of the existing operating and most under construction nuclear power plants has few design monitoring items, high equipment failure rate, frequent on-site maintenance by operators, and can only be used for routine environmental monitoring. After the nuclear accident at the Fukushima Nuclear Power Plant, the surrounding environmental radiation monitoring system was destroyed, and it did not serve the function of providing monitoring data for decision makers. In 2012, the National Nuclear Safety Administration issued the "General Technical Requirements for Improvement Actions for Nuclear Power Plants after the Fukushima Nuclear Accident (Trial)", which clearly put forward the requ...
