Dear Sir:

Saxton Nuclear Fatility Operating License No. DPR-4 Docket No. 50-146 Second Quarter 1991 Containment vessel Sump Results On June 20, 1991, the second quarterly inspection of the year was conducted at the Saxton Nuclear Experimental Corporation (SNEC) facility, During this inspection, water was founu present in the Containment vessel (CV) sump and a sample.was taken for. radioisotopic analysis, lhe results ol the analysis were received on August 13, 1991 and indicated that the activity concentration of Sr-90 and Cs-137 exceeded the " Limits for Unrestricted Release" identified in 10 CfR 20, Appendix B, Table 11, Column ?, and is reportable under section 5.a.3 of the SNEC Technical Specification (IS).

Per the 15, the results of the analysis for the above isotopes were

-verbally reported to Mr. J. Kottan (NRC Region 1) on August 13, 1991.

The attached Exhibit 1 identifies the reportable results of the SNEC CV sump water analysis for the second quarter of 1991.

It should be noted that the CV sump volume is 325 gallons and was filled with approximately 160 gallons of water.
