S. Nuclear Regulatory Commission Attentiom Document Control Desk Washington, DC 20555 Dear Sir Saxton Nuclear Facility Operating Lic*mse No. DPR-4 1
I Docket No. 50-146 First Quarter 1991 containment Vessel Sump Results i
on March 21, 1991, the first quarterly inspection of the year was conducted at the Saxton Nuclear Experimental Corporation (SNEC) facility.
During this inspection, water was found present in thn Containment Vessel (CV) sump and a sample was taken for radioisotopic analysis.
The results of the analysis were received on May 20, 1991 and indicated that the activity concentr4 tion of Sr-90 und 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).
Per the TS, tha results of Lt.e snalywis for the above isotepes were verbally l
reported to Mr. J.
Roth (NRC Region I) on May 20, 1991.
The attached Exhibit 1 identifies the reportable results of the SNEC CV sump water analysis for the first quarter of 1991.
It should be noted that the CV sump volume is 325 gallons and was filled with approximately 150 gallons of water.

1 The water in the sump originates from condensation on the inside of the CV, and is a consequence of a breathor pipe, installed during the initial decommissioning, which permits the CV to breathe with changes in atmospheric i
temperaturse.
This water poses no threat to the environment or to the health l
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 $.a.
I Sincerely, i
