. The staff, with technical assistance from its contractor, the Idaho National Engineering and Environmental Laboratory (INEEL) has reviewed and evaluated the information provided by the licensee.

The staff concludes that the proposed alternative testings for Requests for Relief Nos. PRS-1C, Revision 1, PRS-1E, and PRS-1F are authorized pursuant to 10 CFR 55a(a)(3)(i), in that the proposed alternatives provide an acceptable level of quality and safety.

The staff's evaluation and conclusions are contained in the enclosed Safety Evaluation.
