4. Measurements and Approximations of Total Radioactivity a., b. & c. 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 4

, least monthly to determine the quantity of noble gas activity j released for the month based on the average vent flowrates re-corded 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 j exceeding 15% within one hour. The vent flowrates for the shield auxiliary, service buildings, and condenser vacuum ex-( haust are determined and recorded twice a shift.

The quantity of noble gases released through the shield build-ing due to purging or venting of containment and releases of waste gas decay tanks are also determined.

l- 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.

b. & c. Iodines and Particulates
Iodine and particulate activity is continuously monitored and re-corded. Charcoal and particulate samples are taken from the shield auxiliary building exhausts and analyzed at least weekly to deter-mine 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 average vent flowrates recorded for the sampling period and acti-vity concentration.

i The vent flowrates form the shield and auxiliary buildings are recorded twice a shift.

The total particulate and iodine activity released for the month is then determined by summing all df the activity released from the shield and auxiliary buildup 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 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 deterined by summing the activity content of each batch discharged during the month.

(2) Continuous Releases and Periodic Continuous Releases Total gamma isotopic' activity concentration is determined daily on a composite sample. The total curie content of the continuous release is determined daily 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.

Allowance is made for plus or minus one sigma counting error associated with the total gamma isotopic analyses.

9 SEQUOYAH NUCLEAR PLANT UNITS 1 & 2 PROCESS CONTROL PROGRAM CHANGES

The Sequoyah Nuclear Plant Process Control Program (PCP) was first issued and approved by the Commission in February, 1980. Since its original issue, the PCP has been changed.once to reflect a change in solidification vendors as previousiv, reported.

~

On May 18, 1982, the Plant Operations Review Committee (PORC) approved another change to the PCP as a result of the termination of contract with Chem-Nuclear Systems and issue of contract to Hittman Nuclear and Development Corporation (Contract #82P68-180480). The vendor change was based upon economic considera-tions only.

The new Hittman contract stipulates the use of cement for the solidifying media. The Chem-Nuclear system provided for alternative solidification media (i.e., cement or urea formaldehyde). The new PCP contained within the Hittman contract provides for a solidified product which satisfies all current burial site and transport criteria. It has been determined that the PCP change does not reduce overall conformance to existing radioactive waste regulations.

The revised PCP has been incorporated into plant written procedures in detailed step-by-step format.
