Performance Test of Cemented Waste Form

With the most comprehensive cemented waste form performance testing & assessment platform and capabilities within China, CIRP has developed a number of special equipment for sample preparation, pretreatment and performance testing. CIRP has undertaken more than 95% of the cement solidification performance testing and assessment assignments of domestic nuclear power TES system, as well as similar projects of NUKEM in Germany, AVERA in France and Karachi NPP in Pakistan.

Radioactive Gas Purification
CIRP provides product series of iodine adsorber (type I, II, and III, reusable folding iodine adsorber and impregnated activated carbon), HEPA filters, and inert gas delay bed system, the supply percentage of type I folding iodine adsorber and impregnated activated carbon achieved 100% domestically, and 100% of commissioning test and regular test for the performance assessment of the air purification system at nuclear facilities are undertaken by CIRP. Furthermore, CIRP is the only institution in China that can evaluate the performance of HEPA filters and iodine adsorber in nuclear ventilation systems with different methods.

Radioactive Water Treatment

CIRP has formed a complete system covering design, R&D, production, testing and technical services of water filters and cartridges applied to NPPs, which is domestically leading and internationally advanced. Product types meet the needs of both pressurized water reactor and heavy water reactor, with filter fineness ranging from 0.1 to 100 μm. 

The water filter and cartridge series independently developed by CIRP is the only product with on-site practical application in China. Since 2020, multiple batches of filter elements have been supplied to Ningde, Fuqing, Haiyang, Sanmen and other nuclear power plants, which not only reduced the operating costs of NPPs, but also achieved excellent on-site application results.

Spent Radioactive Source Conditioning

The spent radioactive source conditioning technology refers to withdrawing spent radioactive sources temporarily stored at the user site from the original container, with spent radioactive source conditioning device, and encapsulating multiple spent radioactive sources in one or several packaging tubes, which are subject to containment in thin-walled stainless steel container, and this container is to be encased in long-term storage container to finalize the process of safe storage / disposal. CIRP is competent in the design, construction and operation of waste radioactive source conditioning equipment and is able to undertake maintenance operations and technical training services.

Radioactive Waste Oil Purification Treatment

The radioactive waste oil treatment technology is characterized with simple process, safe operation and reduced volume. The supporting treatment device is compact in size and movable, which can be directly applied to the treatment of radioactive waste oil produced by nuclear facilities. The total activity concentration of γ in waste oil is less than 0.1 Bq/g. With the designed capacity of 200 L/batch, the radioactive waste oil treatment device has been operating stably for more than 1,500 hours at the Daya Bay Nuclear Power Plant with accumulated of 5,000L waste oil being treated. The combined treatment method of oxidation aging and circulating filtration used in waste oil treatment can also be used for the treatment of waste organic solvents (bolt cleaning detergent) and other waste organic phases.
