大型高温反应堆发电厂在设计和安全方面遇到的几乎所有问题都与较大反应堆堆芯的物理尺寸有关。我们的分析表明，它是可行的细分为一个较大的反应堆堆芯模块化的单位，类似于使用几个较小的单位，而不是一个大的单位的常见做法。在串联连接几个模块化反应堆单元时，除了利用小型球床堆芯的有利安全特性之外，仅通过简单的技术设计就可以获得更大的功率输出。可以表明，对于这些堆芯，停堆系统和衰变热排出系统等经典安全装置在风险评估方面失去了主导地位。
Nearly all problems encountered in large high-temperature reactor power plants with respect to design and safety are related to the mere physical size of a larger reactor core. Our analyses show that it is feasible to subdivide a larger reactor core into modular units, analogous to the common practice of using several smaller units instead of one large unit. In connecting several modular reactor units in series, a larger power output can be obtained by merely using simple technical designs, in addition to utilizing the favorable safety characteristics of small pebble-bed cores. It can be shown that for these cores such classical safety devices as shutdown systems and decay heat removal systems lose their dominance in respect to risk evaluations.
