ENCLOSURE National Bureau of Standards Docket No. 50-184 Unique Purpose Exemption Request Request for Additional Information

1. An important justification for a unique purpose exemption is that the reactor program contributes significantly to the national interest and cannot be accomplished without the use of HEU fuel. In 1984, a Major Materials Facility Committee of the National Research Council of the National Academy of Sciences reviewed major neutron research facilities in the United States. Please identify and discuss any comments or reconnendations of this Committee, or any comparable group, with respect to your facility, that may establish your reactor program's contribution to the national interest.

2. Provide a quantitative discussion which demonstrates that your reactor core is'of special design and could not perform its intended function without using HEU fuel. Include the bases for this determination.

3. Research projects which are based on neutron flux levels or spectra attainable only with HEU fuel can be considered as a basis for a unique purpose exemption. Identify and provide quantitative estimates, and-the bases therefore, cf the impact on each of the programs discussed in your September 19, 1986 cubmittal, that would result from the changes in neutron flux densities, fluences, neutron spectra, and background noise if LEU fuel were substituted for HEU fuel in your facility.
