  1. IAEA-CN-178/12-04 Introduction of the Large Scale Reprocessing Plant in China DAI YUNXIU China National Nuclear Corporation June 3, 2010

  2. Presentation Outline 1、Basic information of the Plant 2、Progress of the Project 3、Site characteristics 4、R＆D of reprocessing 5、Product outlet 6、Concluding remarks

  3. 1、Basic information of the Plant Product form: UO3 and (U)PuO2

  4. 1、Basic information of the Plant Plant capacity: reprocessing capacity 800t/a Storage capacity 3,000～6000tU

  5. 1、Basic information of the Plant Design basis spent fuel: AFA-3G spent fuel Cladding material: M5 alloy Pellet material: UO2 235U initial enrichment：4.45%（by weight）Burnup：45000 MWD/tU （average） 55000 MWD/tU （max.） Cooling time：≥8 years

  6. 1、Basic information of the Plant Options of fuel receipt and storage: Wet unloading method Fuel storage pool

  7. 1、Basic information of the Plant Head-end: Cut off by horizontal Shearing Machine Dissolved continuously in Dissolver Clarified by Settling Centrifuge

  8. 1、Basic information of the Plant Separation and Purification:

  9. 1、Basic information of the Plant Finishing: U stream concentrated by Evaporator denitrated by Fluidized Bed (U)Pu stream precipitated, filtrated and calcinated of (U)Pu oxalate

  10. 1、Basic information of the Plant Radioactive waste treatment options For radioactive gaseous waste First remove NOx ,aerosol, C, and I etc., and then release into atmosphere

  11. 1、Basic information of the Plant For radioactive liquid waste HLLW Process ILLW Non-process ILLW and LLLW Spent solvent

  12. 1、Basic information of the Plant For radioactive solid waste Being classified and treated. Conditioned IL-LL solid wastes go to IL-LL waste disposal site. Conditioned α and HL solid wastes will be temporarily stored pending final deep geological disposal.

  13. 1、Basic information of the Plant Construction planning: Receiving spent fuel in 2018 Start up reprocessing in 2025

  14. 2、Progress of the Project Siting: Performed both in the coast and inland area. The preliminary survey work of the inland site has been performed.

  15. 2、Progress of the Project Preliminary feasibility study and the project proposal : The preliminary feasibility study works such as technical options, investment estimation and economic analysis etc. have been performed. The preliminary feasibility study report and the project proposal have been submitted to government for approval.

  16. 2、Progress of the Project Cooperation with foreign countries: CNNC has contacted and discussed on the potential cooperation with relevant organizations and enterprises of Russia, France and UK. China welcome the countries or enterprises which have reprocessing ability to cooperate with China, if the conditions are permissible.

  17. 3、Site characteristics • The site is located in Gansu province. • The topography of the site is flat, and the slope of natural topography is about 1%. • The population density is very low within 20km. • There are no industrial, agricultural and health facilities within 15 km of the site.

  18. 4、R&D of reprocessing Ability : Had constructed the reprocessing plant for the production reactor spent fuel. Has gain preliminary success for the hot test of the pilot plant for power reactor spent fuel. Has mastered the design and construct tech. R&D : Approved the R&D of reprocessing to further research key reprocessing technology, wishing to enable China’s reprocessing technology reach the world’s advanced level nowadays.

  19. 5、Product outlet Main outlet of the Products is to recycle them in thermal or fast reactors after being manufactured into UO2 or MOX fuel. Chinese government is undergoing the study for the problem of the outlet of the Pu product, one of the options is to recycle them into fast reactors directly.

  20. 6、Concluding remarks China has decided to construct a large-scale spent fuel reprocessing plant, which is an important activity on the management of spent fuel in China. China has preliminarily mastered the design and construction technology of spent fuel reprocessing plant. China has confidence that the large plant can be successfully constructed. In order to speed up the construction, China welcome the countries or the enterprises which have reprocessing ability to cooperate with China, if the conditions are permissible.
