很久以前,科学家们曾提出过一种生产核弹头用的氚的方案,现在这一方案在美国又获得人们的青睐。国立洛斯阿拉莫斯实验室、国立布鲁克海文实验室和威斯汀豪斯汉福德公司的科学家和工程师们不久将向美国国防部呈交一份他们编写的报告,主张修建一座巨型线性质子加速器来生产氚,加速器所用的电力可由水电站发出的多余电力提供。美国生产核弹头用的氚的核工厂只有一家,即萨凡纳河核工厂,但核厂因为设备过时已于去年春天关闭,从而迫使美国国防部不得不考虑用其它方法生产氚。去年夏天,国防部宣布它计划修建两座新的生产氚的反应堆,一座是重水型反应堆,拟建在萨凡纳河原工厂处,另 Long ago, scientists had proposed a program for the production of tritium for nuclear warheads, which is gaining popularity in the United States. Scientists and engineers at the National Los Alamos Laboratory, National Brookhaven Laboratory and Westinghouse Hanford will soon submit a report to the U.S. Department of Defense about their preparation of a giant linear proton Accelerator to produce tritium, the power used by the accelerator can be provided by the excess power from the hydropower station. The United States has only one nuclear power plant for producing nuclear warheads, namely the Savannah River Nuclear Plant. However, the nuclear plant was shut down last spring because the equipment was outdated, forcing the U.S. Department of Defense to consider other ways to produce tritium. Last summer, the Department of Defense announced that it planned to build two new tritium-producing reactors, a heavy water reactor to be built at the Savannah River former factory and another
