本文提出一种以发展聚变动力为主的共生式途径。它以当前正在出现的这一代聚变物理试验堆为起点,分成两路进行,一路是纯聚变堆,另一路是单个的氘发生器,可能是聚变裂变混合堆,它给纯聚变堆补充所需的氘。这两类堆长期结合共生,配合发展.形成一系需氚的纯聚变堆和一系供氚的混合堆,统一优化,保持氚自给,消耗氘锂和快中子裂变材料,提供净输出功率。 对纯聚变堆方面,放弃了传统的氚自给这一基本要求。能量的有效回收成为设计:的主要前提。优化的结果,用12—15厘米厚的含锂的水作为中子慢化回收能量的介质,附带地还能再生所耗氚的80％。不足的20％稍多的氚,将长期地由一个具有低Q聚变芯并依照生产氚的要求来改型并优化的一比一聚变裂变堆来补充。共生的两个堆,尺寸都较小,在等离子体物理和工程上有一些优点。对共生堆和具有相等总输出功率的,一般氚自给聚变堆作了比较,表明在动力经济上有相当大的收益。 简单地讨论了几种有关的概念。
This paper proposes a symbiotic approach focusing on the development of fusion dynamics. Starting from the current generation of fusion physics test reactors, it is split into two paths, one pure fusion reactor and the other a single deuterium generator, possibly a fusion fission hybrid reactor, which complements the pure fusion reactor Deuterium. These two types of long-term symbiotic symbiosis, with the development of the formation of a series of tritium-only pure fusion reactor and a series of mixed tritium reactor, unified optimization, maintain tritium self-consumption, consumption of deuterium and fast neutron fission material, to provide net output power . For pure fusion heap, give up the traditional tritium self-sufficiency this basic requirement. Effective energy recovery becomes the main prerequisite for design. As a result of the optimization, a 12-15 cm thick, lithium-containing water is used as a medium for moderating energy recovery, incidentally 80% of the tritium consumed. Less than 20% of the tritium will be supplemented by a long-term, one-fictitious fusion fission reactor with a low-Q fusion core modified and optimized to meet the requirements of tritium production. Both of the symbiotic stacks are smaller in size and have some physical and engineering benefits. A comparison of the symbiotic stack with a general tritium self-contained fusion stack with equal total output power shows that there is substantial gain in power economy. A brief discussion of several related concepts.
