In addition to the generic URL and site-specific URL, a concept of "areaspecific URL", or the third type of URL, is proposed in this paper. It is referred to as the facility that is built at a site within an area that is considered as a potential area for HLW repository or built at a place near the future repository site, and may be regarded as a precursor to the development of a repository at the site. It acts as a "generic URL", but also acts as a "site-specific URL" to some extent. Considering the current situation in China, the most suitable option is to build an "area-specific URL" in Beishan area, the first priority region for China's high-level waste repository. With this strategy, the goal to build China's URL by 2020 mav be achieved, but the time left is limited.展开更多
