Research was conducted in the classification of lower-enrichment space nuclear reactor fuel in terms of its graded safeguards category and attractiveness level. Specifically, fuel with a 235U enrichment of less than 50% and greater than 20% (i.e., 49.9%) meets the criteria for a lower category of special-nuclear-material control and accountability. This fuel is considered to have an attractiveness level of 'D' and therefore is classified as Category II material rather than the highest and most rigorous Category I. The net result is a more cost-effective and facilitated approach to the protection, control, and accountability of this material. The views expressed in this document are those of the author and do not necessarily reflect agreement by the Government.
