SUBJECT:

CONTAMINATED WATER IN THE CONTAINMENT SUMP

Dear Mr. Elsasser:

An internal review of our records for the first quarter of 1986 indicates that a 15 day written notification of water in the lower portion of the Saxton Nuclear Experimental Facility's containment vessel (CV) was not transmitted to your offices. Telephone notification of the presence and analyses results of the water was made on February 20, 1986 to Mr. R. Summers, Region I, U.S.

Nuclear Regulatory Commission. The SNEC Technical Specifications require a followup report within 15 days per Section B, paragraph 5. This omission is the result of an inadvertent oversight. Notification of this oversight was made by our licensing representatives to Mr. Don Haverkamp, Region I, U.S.

NRC, who advised us to submit the written notification late.

The water in question was observed in the CV sump during the first quarter inspection of the facility on February 7, 1986. A sample was taken and analyzed for radionuclide content. The results are presented in Exhibit 1.

Both cesium-134 and 137, and strontium-90 were found to exceed the units set forth in 10 CFR 20, Appendix B, Table II, " Limits for Unrestricted Release".

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 it has been in the past.

Mr. Thomas Ele: sacr Decembar 22, 1986 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 systen 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.

If you have any questions concerning this report, please call me at (201) 316-7594.

Sincerely, R. W. Heward, Jr.
