Dear Sirs:
Saxton iluclear Facility Operating License No. DPR-4 Docket No. 50-146 Contaninated Water From the Containment Vessel Sump On June 28, 1988, the second quarterly inspection of 1988 was conducted at the Saxton fluclear Experimental Corporation (SNEC) f acility.
During this inspection, water was noted to have collected in the Containment Vessel (CV) sump. Radioisotopic analysis of tt.is water revealed it to contain radionuclide concentrations of Co-60, Cs-137, Cs-134, and Sr-90 in excess of 10 CFR 20 Appendix B, Table II, "Limits for Unrestricted Release", and is reportable under Section 5.a.3 of the SNEC Technical Specifications.
The analysis resuits are presented in Exhibit 1, attached.
The presence of this water poses no threat to the environment or to the public health and safety since there are no release paths from the CV sump to the environment. When appropriate, the water will be properly disposed of as it has been in the past.
The water originates from condensation on the inside of the CV.
The condensation is a consequence of a breather pipe, installed during the initial deconnissioning, which permits the CV to breathe when changes in atmospheric temperature occur.

U. S. ' Nuclear Regulatory Commission Page 2-It.is~ apparent.that the influx of. water to the sump cannot be readily-terminated without installation of a system to-control the internal atmosphere of the CV.
This action is not deemed necessary since the water has no pathway to the external environment. We will continue to periodically monitor, remove and take the appropriate steps to secure and dispose-of this water.
Sincerely, R. W. Heward, Jr.
