Contaminated Water From the containment Vessel Sump

\\

.On September 19, the' third quarterly inspection of 1989 was conducted at the Saxton Nuclear Experimental Corporation-(SNEC) facility.

During this inspection, water-was found to have collected in the Containment vessel'(CV) l L

sump. The Radioisotopic results of this water, received on November 14, 1989, j

indicated that only the concentration of Cs-137 exceeded the " Limits for l

l Unrestricted Release" identified in 10CFR20, Appendix B,: Table II,.and ir 4

reportable under section 5.a.3 of the SNEC Technical Specifications.

The l

results of the concentration of Sr-90, Cs-134, and Co-60, although within the j

l 10CFR20 limits, were questioned by GPUN, and a roanalysis was requested from the analysis laboratory. A preliminary telephone conversation with the

~

analysis laboratory indicated that the value for-Sr-90 may also exceed j

allowable limits.

Mr. C. Cowgill of the NRC was apprised of the above, via l

telephone,.on Dec.

1, 1989.

'On December 6, 1989 the results of the reanalysis for the above isotopes were received and evaluated by GPUN.

As indicated earlier the Radioisotopic value i

for Cs-137 is still in excess of the allowable limits.

In the reanalysis, the value did, however increase. As for the other isotopes, the value for Sr-90 j

was also in excess of the limits stipulated in 10CFR20, Table II.

The NRC was I

j apprised of the results of the reanalysis on December 6, 1989.

Exhibit 1, l

enclosed, provides the reportable analysis results of the third quarter

' inspection.'

The water in the sump originates from condensation on the inside of the CV,

/

'and is~a consequence of a breather pipe,-installed during the initial decommissioning, which permits the CV to breathe with changes in atmospheric temperatures.

This water, poses no threat to the environment or

.to the health and safety of the_public because there are no release pathe to the external environment from the CV sump. When appropriate, the water will be properly disposed of, as it has been in the past.

We will continue to periodically monitor, remove'and take the appropriate

~

steps to secure and dispose of this water.
