摘要：Lack of energy is a serious threat to theprosperity of many developed states that have access to or plan to use nuclearpower. The paper describes a concept for solving two major problems related tothese conditions, namely safe disposal of spent reactor fuel and generation ofelectric energy or hot fluid by use of heat produced by the disposed waste. Thechallenge in storing spent nuclear fuel can be met with by installing suchhighly radioactive waste in deep boreholes with fuel rods encapsulated incanisters of copper-lined iron or titanium. Electric energy can be generated byutilizing the accumulated heat in the same rock mass by pumping up hot water orclayey mud from series of deep holes bored parallel and between correspondingholes with nuclear waste. The amounts of heat in each of the hot-water holesoverlap and raise the initial rock temperature at 1,500-3,000 m depth to about80-90oC after some 50 years and to 70-80oC in 500 years,after which the temperature in the hot-fluid holes goes down successively tothe initial value 60-70oC in about 500 years. If these holes aresubsequently deepened from 3,000 to 5,000 meters, utilization of the hot fluidcan continue for another 500 years.
