'+9.....,o SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT N0. 17 TO FACILITY OPERATING LICENSE NO. R-75 OHIO STATE UNIVERSITY DOCKET N0. 50-150
1.0 INTRODUCTION
By letter dated January 2,1997, Ohio State University (the licensee) requested that License Condition 2.8 be changed to increase the possession limit from 10 grams to 30 grams of highly enriched Uranium-235 in the form of fission chamber linings, foil targets, and other research appiications. Also, the licensee has requested that the characterization of this Uranium-235 be changed from "93% enriched" to " highly enriched".
2.0 EVALUATION The licensee's reason for requesting an increase in the possession limit from 10 grams to 30 grams is that the present 10 gram limit will not accommodate a pending research application. The staff finds that the increase in the possession limit is acceptable and that it does not raise the security level requirements of the facility.
The reason why the licensee would like to change the characterization of this material is because it provides greater flexibility in the purchase of fission chambers, foils, and other research applications.
For instance, the licensee orders a nominal 93% enriched material, but in some cases it may be somewhat greater, and this would constitute a violation of the present license condition. Therefore replacing the enrichment as " highly enriched", which is i
defined in 10 CFR 50.2 as " fuel in which the weight percent of U-235 in the uranium is 20% or greater" provides the flexibility required. The staff considers possession of 30 grams of U-235 with enrichments above 93%
acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a change in a requirement with respect to the installation or use of facility components located within the restricted areas defined in 10 CFR Part 20.
