近年来，放射性废物的地质处置侧重于将高、中放射性废物放置在500-800米深的地下洞穴中。尽管迄今为止在这一方法上花费了数十亿美元，但由于难以找到合适的场地并向公众和监管机构证明可以制定强有力的安全案例，因此在几个国家实施处置方案的努力受挫，而且任何地方都不存在乏核燃料处置设施。深钻孔处置的概念在20世纪50年代首次被考虑，但被拒绝，因为它被认为超出了现有的钻井能力。钻井和相关技术的改进以及密封方法的进步促使人们重新审查这一处置高放射性废物，包括乏燃料和钚的备选办法。自20世纪50年代以来，深井研究所需的投资很少。然而，深井处置提供了一个潜在的…
In recent years, geological disposal of radioactive waste has focused on placement of high- and intermediate-level wastes in mined underground caverns at depths of 500–800 m. Notwithstanding the billions of dollars spent to date on this approach, the difficulty of finding suitable sites and demonstrating to the public and regulators that a robust safety case can be developed has frustrated attempts to implement disposal programmes in several countries, and no disposal facility for spent nuclear fuel exists anywhere. The concept of deep borehole disposal was first considered in the 1950s, but was rejected as it was believed to be beyond existing drilling capabilities. Improvements in drilling and associated technologies and advances in sealing methods have prompted a re-examination of this option for the disposal of high-level radioactive wastes, including spent fuel and plutonium. Since the 1950s, studies of deep boreholes have involved minimal investment. However, deep borehole disposal offers a potentia...
