安全处置放射性废物，特别是乏燃料、前军用裂变材料和其他形式的高放废物，是当代科学面临的主要挑战之一。目前，国际上首选的解决办法是在一个开采和设计的多屏障处置库中进行地质处置。虽然这通常被称为“深层”处置，但从地质学角度来看，所涉深度通常相当浅。一个新的计划，目前正在开发中，高温处置的高放废物集中在很深的钻孔概述。最近在大陆地壳岩石和几公里深处的流体方面的知识进展表明，更深的处置可能为高放废物问题提供更安全和环境上更可接受的解决办法。新计划旨在利用这一潜力，同时将废物的有问题的热量输出转化为优势。它似乎提供了显着的好处，无论是开采储存库和早期的钻孔方案，特别是在安全方面。(C)1999 Elsevier Science Ltd.保留所有权利。
Safe disposal of radioactive waste, especially spent fuel, ex-military fissile materials and other forms of high-level waste (HLW), is one of the major challenges facing contemporary science. Currently, the internationally preferred solution is for geological disposal by interment in a mined and engineered, multi-barrier repository. Although this is often referred to as "deep" disposal, the depths involved are usually quite shallow in geological terms. A new scheme, currently under development, for the high-temperature disposal of concentrated HLW in very deep boreholes is outlined. Recent advances in the knowledge of continental crustal rocks and fluids at depths of several kilometres suggest that much deeper disposal might offer a safer and environmentally more acceptable solution to the HLW problem. The new scheme seeks to capitalise on this potential while turning the problematical heat output of the waste to advantage. It appears to offer significant benefits over both mined repositories and earlier borehole scenarios, particularly in terms of safety. (C) 1999 Elsevier Science Ltd. All rights reserved.
