Abstract

The invention provides a main steam pipeline radiation monitor method and a device thereof. The method includes: setting a 16N radiation monitor and an inert gas radiation detector in a main steam pipeline, wherein that 16N radiation monitor judges the leakage condition of a steam generator by monitoring 16N nuclide and the inert gas radiation detector monitors the total activity concentrations of85Kr and 133Xe in the main steam pipeline; a 16N in situ radiation processing module is connected to the 16N radiation monitor, and an inert gas in situ radiation processing module is connected to the inert gas radiation detector. A computer control section is connected to the 16N radiation monitor and the inert gas radiation detector, the 16N radiation monitor and the inert gas radiation detector receives a control signal of the computer control section, transmits the measured radiation data, and gives an acoustic and optical alarm and indication signal.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant exhaust gas monitoring, in particular to a radiation monitoring method and device for a main steam pipeline. Background technique [0002] The nuclear power plant of the pressurized water reactor nuclear power plant usually consists of two closed circulation loops, called the primary loop and the secondary loop. The primary loop includes nuclear reactors (sealed in pressure vessels), main cooling water pumps, voltage stabilizers and other equipment, and the pressure is maintained at 120 to 160 atmospheres; the secondary loop includes steam generators, condensers, main cooling water pumps and other equipment, and the pressure is maintained at 70 atmospheres. The primary circuit connects the core and the steam generator in the secondary circuit. [0003] After absorbing the heat energy of the cooling water in the primary circuit, the cooling water in the secondary circuit is heated to ...
