o Lv i Enclosure National Bureau of Standards Docket No. 50-184 Unique Purpose Exemption Request Request for Additional Information 10 CFR 550.64(b)(3) requires that any licensee granted a unique purpose exemption from the use of LEU fuel must use HEU fuel of enrichment as close to 20% as is available and acceptable to the Commission.

If fuel of any enrichment from 20% to 93% were available and you were granted a unique purpose exemption, what would be the lowest enrichment fuel that your reactor could use and still reasonably accomplish its primary projects, programs, or commercial activities? In your answer, please justify your final choice of enrichment based upon the physical and technical limitations of your reactor and its supporting programs.
