Dear Sir:

Saxton Nuclear facility Operating License No. DPR-4 Docket No. 50-146 Fourth Quarter 1991 Containment Vessel Sump Results On December 5, 1991, the fourth quarterly inspection of the year was conducted at the Saxton . Nuclear Experimental Corporation (SNEC) facility. During this inspection, water was- Tound present in the Containment Vessel (CV) sump and a sample was taken for radioisotopic analysis.

.The results of the analysis were received on February 20,1992 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 II, Column 2, and is reportable under Section 5.a.3 of-the SNEC Technical Specification (TS).

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

It should be noted that the CV sump volume is 325 gallons and was filled with approximately 172 gallons of water.

e C301-91-0004 SNEC-91-0006 Page 2 The water in the sump originates from condensation on the inside of the CV, and is a consequence of a breather pipe, installed during the initial decommissioning, which permits the CV to breathe with changes in atmospheric temperatures. This water poses no threat to the environment or to the health and safety of the public because there are no release paths to the extarnal environment from the CV sump. When appropriate, the water will be properly disposed of, as it has been in the past.

We will continue io periodically monitor, remove and take the appropriate steps to secure and dispose of this water.

This letter comprises the required written report per th? SNEC TS Section 5.a.

Sincerely,
