i RELEASE OF WASTE CAS STORAGE DRUMS BEFORE 60-DAY HOLDUP PERIOD Technical Specification 3.17B3 requires a special effluent report should the average holdup time of waste gas drums be less chan 60 days.

The following drums had a holdup time of less than 60 days during normal operations in the first half of 1979.

5-27-79 6-15-79 18 845 The average holdup time for the first half of 1979, of all batch releases during normal operations, was 33 days.

The two releases on 3/14/79 were scheduled to make certain decay drum space was available for a 3/15/79 shutdown. The drums

~

contained low levels of noble gas.

The release on 6/15/79 was a discharge of low level noble gas from shutdown activities.
