利用计算模型研究了早期核聚变反应堆对氚增殖比和初始氚库存的要求。对氚库存的时间依赖性计算结果进行了检验，特别是从以下三个方面进行了检验；储存系统中氚库存的倍增时间，以提供下一个工厂的初始库存，储存系统中氚库存恢复到初始值的恢复时间，以及运行期间所需的最小氚储存。采用倍增时间小于3年、回收时间小于1年、最小贮存量大于氚燃烧50天的限度对结果进行评价。在假设燃料处理子系统性能参数合理的情况下，对氚增殖比和初始氚库存量的要求分别为1.10和27.6 kg。如果假设氚处理系统较差，则要求不可避免地会更高。另一方面，即使使用良好的处理系统，需求的缓解也不明显。研究结果表明，要实现氚的自给自足，高性能的氚处理是必不可少的，但还远远不够。参20。， 11个无花果。， 1页。«少
Requirements of tritium breeding ratio and the initial inventory of tritium for early fusion power reactors were investigated with a calculation model. The results of calculated time-dependence of tritium inventory were examined, in particular from the following three points of view; the doubling time of tritium inventory in the storage system to provide the initial inventory of the next plant, the recovery time in which the tritium inventory in the storage system recovers to the initial value and the minimum tritium storage required during the operation. The following limits were adopted to evaluate the results, i.e., the doubling time shorter than 3 years, the recovery time shorter than 1 year and the minimum storage larger than the tritium for 50 days burn up. For a reference case, which assumes reasonable performance parameters of the fuel processing subsystems, the requirements for the tritium breeding ratio and the initial tritium inventory were estimated to be 1.10 and 27.6 kg, respectively. If a poor tritium processing system is assumed, the requirements become inevitably higher. On the other hand, mitigation of the requirements is not conspicuous even with a good processing system. The obtained results suggest that the high performance tritium processing is indispensable,more » but still insufficient for achievement of tritium self-sufficiency. 20 refs., 11 figs., 1 tab.« less
