核动力生产,跟其他工业生产过程一样,所产生的污物必须给予安全管理和处置。有些放射性强的污物更应长期隔离直至衰减到无害的程度。当前,几个国家正考虑在坚硬、结晶状的岩石中建地下洞窟来隔离放射性污物。污物一经置于洞窟,其强放射性污物的衰减——无论是反应堆的燃料消耗或者是由于再生污物的燃料消耗——会影响到洞窟中的基质岩石。为了弄明白岩石对这种热负荷的反应情况,在瑞典中心的Strlpa矿区,(图1)于1971 Nuclear power production, like other industrial processes, produces contaminants that must be safely managed and disposed of. Some radioactive dirt should be more long-term isolation until decay to harmless. Currently, several countries are considering the construction of underground caves in hard, crystalline rocks to isolate radioactive contaminants. Once dirt is placed in caves, the decay of strong radioactive contaminants, either in the reactor’s fuel consumption or due to the fuel consumption of recycled contaminants, can affect matrix rocks in the cave. In order to understand the response of rocks to this heat load, at the Strlpa mine in central Sweden (Figure 1) in 1971
