Measurenent and Approximations of Radioactivity a.

Fission and activation gases:

Continuous discharge - vent stack samples are analyzed monthly and the levels of activities determined are assumed to hold for the period between samples. The continuous vent stack monitor reading is used as a basis for increasing periodic sample frequency. Air ejector is sampled monthly and on any increase in continuous air ejector monitor reading.

Batch discharges - direct measuremnt of waste gas holdup drtms are made

~

before discharge. Containment vents and purges are analyzed b/ direct measuremnt of tne containment atmosphere at periodic intervals during the discharge.

s b.

Continuous nonitoring of primary vent stack iodines are maia by weekly measurenents of an in-line charcoal filter.

Batch discharges - direct neasurement of waste gas holdup drums before discharge.

Abnormal Releases a.

Liquid There were no abTormal liquid releases during t.his reporting period.

b.

Gaseous DurIng an investigation of a change in slope of the containment air value on April 17, 1981, it was discovered that a valve in a 1/4 inch temporary line off the containment air particulate detector had been left open for a period of 9 days. This caused an unplanned radioactive release through the primary auxiliary building vent system particulate and charcoal filters into the primary vent stack. Total specific nuclide activity released ms 3.69E-2 Ci. This activity as well as that of the individeal j

nuclichs are reported in Tables lA and 18 of this mni-annual report.

The following table is not attached since there was no applicable release c.

during this reporting perioS.

RELEASE OF WASTE GAS STORKE DRLMS S3 FORE 60-DAY HOL_lyJP PERIOD j

Technical Specification 3.17B3 requires a special effluent report should the (verage holdup time of waste gas be less than 60 days.

The following drums had a holiup time of less than 60 days during normal operations in the 1st half of 1981.

12/23/80 1/10/8L 18 9.16 The average hcadup time for the first half of 1981, of all decay drums during normal operatiu, was 40.7 days.

E;rly release of decay drums b7 Permit No's 536 and 537 was required because

• decreased available stor.ne space in conjunction with a large volme of gas w

gent: rated by plant startup darina the December shutdown for RCP seal repair.

Decreased storage space resulted fra leaking valves on two decay drms making them unavailable for use. No radioactive release resulted from the defective valves.
