Dr. WANG Ju,obtained his BS degree from the Nanjing University in 1984, majored in
Uranium Geology and Geochemistry. He started his career
at the BRIUG in 1987, and then held a PhD degree in Geology from the BRIUG. Dr.
Wang is now the Vice-President of the Beijing Research Institute of Uranium
Geology (BRIUG), as well as the Head of the CNNC Key Laboratory on Geological
Disposal of High-level Radioactive Waste. He is responsible for R&D project
management and international cooperation. His current research focuses on
geological disposal of high-level radioactive waste. He also held various
positions for BRIUG’s Environment Research Center as vice director, senior
scientist, project head and chief scientist from 1995 to 2004. Dr. Wang is
currently the president of Commission on Radioactive Disposal of International
Society for Rock Mechanics and Rock Engineering (ISRM), and the president of
Commission on Waste Underground Disposal of the Chinese Society for Rock
Mechanics and Engineering (CSRME).
Abstract:With
the rapid development of nuclear power in China, the disposal of high-level
radioactive waste (HLW) has become an important issue for nuclear safety and
environmental protection. Deep geological disposal is internationally accepted
as a feasible and safe way to dispose of HLW, and underground research
laboratories (URLs) play an important and multi-faceted role in the development
of HLW repositories. This paper introduces the overall planning and the latest
progress for China’s URL. On the basis of the proposed strategy to build an
area-specific URL in combination with a comprehensive evaluation of the site
selection results obtained during the last 33 years, the Xinchang site in the
Beishan area, located in Gansu Province of northwestern China, has been
selected as the final site for China’s first URL built in granite. In the
process of characterizing the Xinchang URL site, a series of investigations,
including borehole drilling, geological mapping, geophysical surveying,
hydraulic testing and in situ stress measurements, has been conducted. The
investigation results indicate that the geological, hydrogeological,
engineering geological and geochemical conditions of the Xinchang site are very
suitable for URL construction. Meanwhile, to validate and develop construction
technologies for the Beishan URL, the Beishan exploration tunnel (BET), which
is a 50-m-deep facility in the Jiujing sub-area, has been constructed and
several in situ tests, such as drill-and-blast tests, characterization of the
excavation damaged zone (EDZ), and long-term deformation monitoring of
surrounding rocks, have been performed in the BET. The methodologies and
technologies established in the BET will serve for URL construction. According
to the achievements of the characterization of the URL site, a preliminary
design of the URL with a maximum depth of 560 m is proposed and necessary in
situ tests in the URL are planned.
