Dear Sir:

Saxton Nuclear facility Operating License No. DPR-4 Docket No. 50-146 Second Quarter 1991 Containment Vessel Sump Results On June 20, 1991> e second quarterly inspection of the year was conducted at the Saxton Nu . ear Experimental Corporation (SNLC) facility. During this inspection, water was found present in the Containment Vessel (CV) sump and a sample was taken for radioisotopic analysis.

The results of 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, lable !!,

Column 2, and is reportable under Section 5.a.3 of the SNEC Technical Specification (TS).

Per the TS, 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 t h( (V surip volume is 325 gallons and was filled with approximately 160 gallons of water, i

The water in the sumo originates from condensation on the inside of the CV, i

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 external environment from the CV sump. When appropriate, the water will.be properly disposed of, as it has been in the past.

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

This letter comprises the required written report per the SNEC TS Section
