Dear Sirs:

Saxton Nuclear Facility Operation License No. DPR-4 Docket No. 50-146 Contaminated Water From the Containment Vessel Sump On March 10, 1987, the first quarterly inspection of 1987 was conducted at the Saxton Nuclear Experimental Corporation (SNEC) facility. During this inspection, water was noted to have collected in the Containment Vessel (CV) Sump. Radioisotopic analysis of this water revealed it to contain radionuclide concentrations of Cs-137 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 results 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 for the water from the 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 decommissioning, which permits the CV to breathe when changes in atmospheric temperature occur.

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,
