一、核废物的处置问题纵观全球,放射性废物的景状是相当令人吃惊的,根据一个估计,到1978年底为止,已知世界上三十五个国家共建造了六百二十七座反应堆。如果这个估计过高,另一项估计表明,在1983年,除了现有正在运行的二百九十四座反应堆外,还计划建造200多座反应堆。根据第三种估计,在1975年,有一百七十座反应堆,到1980年,增加到四百二十座,到1985年,后一数字还可能再翻一番。 I. DISPOSAL OF NUCLEAR WASTE Throughout the world, the landscape of radioactive waste is quite astonishing. According to one estimate, by the end of 1978, it has been known that a total of 627 seats were built in 35 countries in the world reactor. If this estimate is too high, another estimate indicates that in 1983, in addition to the existing 194 nuclear reactors, more than 200 reactors are planned. According to a third estimation, in 1975, there were 170 reactors, which increased to 420 in 1980. By 1985, the latter figure is likely to double again.
