Abstract

There is growing interest in using ^242mAm as a nuclear fuel for space reactors and nuclear batteries. In this paper, we discuss different ^242mAm enrichments, as well as fuel weight requirements, to produce a critical reactor. It was found that relatively low enrichments of ^242mAm, about 10w/o, are enough to guarantee criticality. Such low enrichments might eliminate the need for a ^242mAm enrichment process. It was also found that the best results for low ^242mAm requirements are obtained with a moderator to fuel volume ratio of 10,000.
