Measurements and Approximations of Total Radioactivity 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 fol-loving 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 i shi'ft.

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 cach 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 samma isotopic analyses.

b. & c.

Iodines and Particu16tes Iodine and particulate as-tivity is continuously monitored and re-corded.

Charcoal and particulate samples are taken from the shield and auxiliary building exhausts and analyzed at least weekly to de-termine 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 following 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 aver-age vent flowrates recorded for the sampling period and activity concentration.

The total particulate and iodine activity released for the morth 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 samma isotopic analyses, d.

Liquid Effluents (1) Batch (Radwaste and condensate regenerants to cooling tower blowdown) l Total samma isotopic activity concentrations are determined on each batch of liquid effluent prior to release.

The to-tal curie content of a released batch is determined by sus-mius 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 l

of each batch discharged during the month.

(2) Continuous Releases and Periodic continuous _Re'reasec (Condensate regeneraats, turbine building sump and steam generator blowdown)

Total gamma isotopic activity concantration is determined daily on a composite sample from the condensate system and turbine building sump and weekly for steam generator blow-down.

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 and weekly com-i posite for month.
