Abstract EN
After the successful construction and operation experience of the 10 MW high-temperature gas-cooled reactor (HTR-10), a high-temperature gas-cooled pebble-bed modular (HTR-PM) demonstration plant is under construction in Shidao Bay, Rongcheng City, Shandong province, China.
An online gross γ monitoring instrument has been designed and placed at the exit of the helium purification system (HPS) of HTR-PM and is used to detect the activity concentration in the primary circuit after purification.
The source terms in the primary loop of HTR-PM and the helium purification process were described.
The detailed configuration of the gross γ monitoring instrument was presented in detail.
The Monte Carlo method was used to simulate the detection efficiency of the monitoring system.
Since the actual source terms in the primary loop of HTR-PM may be different than the current design values, a sensitivity analysis of the detection efficiency was implemented based on different relative proportions of the nuclides.
The accuracy and resolution of the NaI(Tl) detector were discussed as well.
