~ Attention: Document Control Desk' Washington, D. C. . 20555 Dear Sirst Saxton Nuclear. Facility Operating. License No. DPR-4 Docket No. 50-146 Contaminated Water From the Containment Vessel Sump on May 23 and June 1, 1989, the second quarterly inspection of 1989_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

. radionuclides concentrations of 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 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 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 decommissioning, which permits the CV to breathe when changes in. atmospheric temperature occur.
