The radiation monitoring capability of CIRP has passed the national CMA certification, CNAS laboratory accreditation and DILAC accreditation, and the proficiency testing provider has been accredited by CNAS. The testing capabilities recognized of CIRP include 10 categories including water, soil and other solids (sediments, fallout, etc.), aerosols, ambient air, building materials and industrial waste, biological and organic matters, surface contamination, accumulative dose, and electromagnetic radiation, covering a total of 83 testing parameters such as γ nuclide, strontium-90, plutonium isotope, uranium isotope, tritium, carbon-14, polonium-210, iron-55, Eu-63, total alpha and total Beta, etc. CIRP is mainly responsible for radiation environment monitoring, advanced analytical technology research, monitoring related equipment development and proficiency testing. Radiation monitoring can be carried out at all stages from the pre-commissioning environmental background survey of nuclear facilities, environmental protection acceptance of the project completion, commissioning and operation to decommissioning and treatment. Possessing the ultra-sensitive measurement facilities such as small multi-nuclide accelerator mass spectrometer (AMS) and multiple tandem inductively coupled plasma mass spectrometer (ICP-QQQ), CIRP can carry out ultra-low level (as low as 10 g) analysis on radionuclide in all ambient medium samples. CIRP has developed and manufactured a variety of equipment for sample collection, pre-processing, nuclide separation, purification and monitoring. Proficiency testing, measurement calibration and inter-laboratory comparison of radionuclide monitoring in water, soil, air, biological and other environmental samples can be provided.
CIRP Carries out routine meteorological observation and analysis in nuclear facilities area, including the construction, operation and maintenance of meteorological gradient tower, statistical analysis of observation data, meteorological condition assessment, like regular weather, extreme weather and engineering meteorological data survey, statistical analysis and design basis assessment.
CIRP conducts on-site meteorological observation and assessment, field test of atmospheric diffusion, physical simulation of wind tunnel and water tank, and numerical simulation service based on high-performance computing environment, with complementary and complete research methods of atmospheric migration and diffusion.
SIMULATION OF DILUTION AND DIFFUSION OF LIQUID EFFLUENTS
IN WATER ENVIRONMENT
CIRP carries out simulation of migration and diffusion behavior of liquid effluent in water environment for various nuclear facility systems, by combining the field tracer experiments, indoor physical models and numerical simulations from the aspects of source term release mode, migration path description and distribution range prediction, aiming to conduct comprehensive research on the temporal and spatial distribution of various liquid effluents in water environment and its environmental impact. CIRP is capable of conducting studies on the adsorption, accumulation, migration and diffusion behavior of radionuclides in soil and groundwater environments, studies on the adsorption, accumulation, migration and diffusion behavior of radioactive wastewater in surface water (rivers, lakes and seas) environments, studies on the dilution and diffusion behaviors of warm drainage in surface water (rivers, lakes and seas) environment as well as field tracer experiment, indoor physical modeling and numerical simulation for coupled simulation project of radionuclide migration in surface water-ground water environment.
CIRP carries out migration simulation of radionuclides in the ecological environment, mainly including the migration and biological transfer process of nuclides discharged from nuclear facilities in different ecological environments (land, freshwater and ocean) and parameter simulation studies, estimation methods of radiation dose rate of non-human species, R&D of bioremediation technology for radioactive contaminated sites, to provide technical support for the ecological environmental impact assessment of nuclear facilities and the environmental remediation of radioactively contaminated sites. By carrying out investigation and analysis on terrestrial ecological environment around nuclear facility sites as well as biological screening reference and recommendations, CIRP is able to provide support for the preparation of environmental impact assessment report of nuclear facilities.
