Transcription

1 Technical Meeting INT/9/173, May 9-11, 2007, Vienna Deep geological disposal of HLW in China: Progress and needs for training in the Network WANG, Ju ( 王驹 ) Beijing Research Institute of Uranium Geology China National Nuclear Corporation (CNNC) 中国核工业集团公司北京地质研究院

2 Tianwan Qinshan 3 Qinshan1, 2 Lin ao Daya Bay Nuclear power plants in Chinese Mainland in 2006: 10 reactors in operation, 1 preparing for operation, 4 under construction

3 By more 1000 MW NPPs will be built in Chinese Main Land Right now, Sanmen NPP, Lin ao (2 nd phase), and Qinshan Phase 2 (2 new reactors) are under construction

4 Preliminary Concept of Chinese HLW Repository

5 Host rock for China s HLW granite

6 Major activities: Site selection and site characterization NW China: Beishan Inner Mongolia SW China E China S China 5 Pre-selected regions for China s HLW repository since 1986

7 Outcrops of granite at Beishan site, NW China

8 drilling sites at BS01, BS02, BS03, BS04 boreholes

10 IAEA Officer, B. Neerdael Visits Beishan site, April 16, 2007 中国核工业集团公司北京地质研究院

11 R&D Guidelines for Geological Disposal published in Feb jointly published by China Atomic Energy Authority Ministry of Sci&Tech., State Environment Protection Administration First government document on HLW disposal

12 Strategy for repository development 3-step strategy ( 三部曲 战略 ) SITE URL Basic study,site selection and site Characterization URL ( may be constructed in the potential HLW repository area) REPOSITORY final repository constructed based on URL

13 Long term plan for HLW disposal : Basic Study and Site Selection Underground Research Laboratory middle of 21 st Century Repository construction

14 Major research area in the coming years Safety assessment site design Fundamental studies

15 Major Research Activities: Strategies, planning and management Engineering Design Site selection and site characterization Radiochemical studies for disposal Safety assessment

16 Major activities (2) Studies on site selection and site evaluation deep geological environment of Beishan site regional geology of Beishan site hydrogeology of Beishan site geophysical survey another pre-selected region technologies for site evaluation digital geoscience database focus on Beishan granite site

17 Participation to TC INT/9/173 Participate the the CRP on Numerical Modelling Host the 1 st RCM on the CRP on Numerical Modelling in September 2006, in Beijing 4 persons have been trained in the Nexwork: Dr. Luo in Aspo, Sweden rock mechanics Mr. Qiu in Sweden modeling Dr. Zhou in Switzerland fundamentals Dr. Ke in USA Itasca Co., in modelling.

18 Participation to TC INT/9/173

19 Participation to TC INT/9/173

20 Needs for training in the Network The Chinese HLW disposal program is involving more young scientists, a strong need for training in many aspects More institutes are involved: BRIUG site characterization CIRP safety assessment BINE engineering design CIAE waste forms, radionuclide migration The proposed number of trainees: 10-15

21 Needs for training cont. Expected training area: Fundamentals Site characterization: 3D modeling, computer codes, fracture modeling Design techniques of URLs, repository Instrumentation for in-situ tests in URLs Testing of EBS Methodologies for safety assessment.
