Fission and Activation Gases, Iodines, and Particulates:
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 sample 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, service buildings, and condenser vacuum 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 determined by summing all of the 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.

Iodines and Particulates Iodine and particulate activity is continuously monitored and recorded.
Charcoal and particulate samples are taken from the shield and auxiliary building exhausts and analyzed at least weekly to determine the total activity released from the plant based on the average vent flowrates recorded for sampling period.
Also, particulate and charcoal samples are taken from the auxiliary and shield buildings once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for 2 days follawing startup, shutdown or a rated thermal power change exceeding 15% within one hour. The quantity of iodine and particulate released from each vent during each sampling period is then determined using the average vent flowrates recorded for the sampling' period and activity concentration.
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 for all sampling periods.
Allowance is made for a plus or minus one sigma counting error associated with the gamma isotopic analyses.
d.
Liquid Effluents (1) Batch (Radwaste and Condensate Regenerants to Cooling Tower Blowdown)
Total gamma isotopic activity concentrations are determined on each batch of liquid effluent prior to release.
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 during the month.
(2) Continuous Releases and Periodic Continous Releases - (Condensate Regenerants, Turbine Building Sump and Steam Generator Blowdown)
Total gamma isotopic activity concentration is determined daily on a composite sample. The total curie content of the continuous release is determined weekly by summing each nuclide's concentration and multiplying by the total volume discharged. The total activity released during the month is then determined by summing the activity content of each daily composite for month.
