Contaminated Water From the Containment Vessel Sump
~
.On September 15, 1987, the third quarterly inspection of 1987 was conducted at the Saxton Nuclear Experimental Corporation (SNEC) f acility.
During this inspection, water was noted-to have collected in the containment vessel sump.
Radioisotopic analysis of this water revealed it to contain radionuclides
- j 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'.a3 of 'the SNEC Technical Specificat ions.
The analysis results are presented in Exhibit 1, att ached.
The presence of this water poses no threat to the environment or to the public health and safety, since there are l
no release paths from the containment vessel 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.
