-a.

Fission and Activation Gases Airborne effluent gaseous activity is continuously monitored and

-recorded. Additional grab samples from the shield, auxiliary, service and condenser vacuum exhausts are taken and analyzed at least monthly to determine the quantity of noble gas activity released for the month based on the average vent flowrates recorded for the sampling period. Also, noble gas' samples:are collected and evaluated for the shield and auxiliary buildings following startup,. shutdown or a rated ' thermal power changes exceeding 15%~within one hour. The vent flowrates for the shield, auxiliary, and' service buildings, exhaust are' determined and' recorded once a' shift.

~

.The quantity of noble gases released through the. shield and auxiliary building due to purging or venting of containment and

' releases of waste gas decay. tanks are also determined.

The total noble gas activity released for the month is then l

determined by summing all'of fthe activity released from each vent for all' sampling periods, the~ activity released from purging or-venting of containment, and the. activity released -

^

from waste gas' decay tank (s).

Allowance is made for a plus or minus _one sigma counting error associated with the gamma isotopic analyses;.

The, vent flowrates from the shield and auxiliary buildings are recorded once a shift.

The' total particulate and iodine activity released for the month is.then determined by summing all of the activity released.from the shield and auxiliary buildings fo'r all sampling periods.

Total gamma irotopic activity concentrations are determined on each batch of liquid. effluent prior,to Lrelease.. The total-curie content of a released batch-is determined by summing each ~nuclide's concentration and multiplying by the total volume discharged. The-total. activity released.during a month

, is then determined by summing the activity. content of.each batch discharged duringithe' month..
