一九五七年,一个从国家科学院—国家研究委员会挑选的地质学家和地球物理学家组成的委员会,提出了在洞室中隔离放射性废物的概念。在研究进行的初期阶段,研究和发展的方向基本上是在盐层中建造核废物隔离室。一九七○年到一九八○年的后五年中,美国、加拿大、瑞典和南德投入废物技术计划的财力和人力都有很大的增加,从而该计划的范围,也扩大到对包括在岗岩、玄武岩、混灰岩和页岩在内的地质介质的研究。那么,二十五年以后,放射性废物洞室地质隔离的原始概念,又将是一个什么样的状况呢?最重要的是,目前美国投入这项活动的资金,已经比一九七○年的金额大得多。根据放射性废物处理国内检查团所作的调查和介绍,卡特总统代表政府于一九八○年二月制订了一个全面的能源部废物处理计划。该计划主要要求在若干岩石类型各异的不同地质环境中,确定四到五个恰当的、具有潜力的隔离室建筑场地,并在一九八五年左右选择其中一个场地,
In 1957, a committee composed of geologists and geophysicists selected by the National Academy of Sciences-National Research Council proposed the idea of isolating radioactive waste in caverns. At the initial stage of the research, the direction of research and development is basically to build a nuclear waste isolation chamber in the salt layer. During the latter five years from 1970 to 1980, the United States, Canada, Sweden, and South Germany invested heavily in financial and human resources, and the scope of the plan also expanded to Research on geological media including rock, basalt, limestone, and shale. Then, twenty-five years later, what is the original concept of geological isolation of radioactive waste caves? What is most important is that the current U.S. funding for this activity has been higher than that of 1970. The amount is much greater. According to investigations and introductions made by the domestic inspection team of radioactive waste disposal, President Carter, on behalf of the government, in February 1980 established a comprehensive waste disposal plan of the Ministry of Energy. The plan mainly requires the determination of four to five appropriate potential isolation building sites in different geological environments with different rock types, and selecting one of the sites around 1985.
