4.. Moncurements and Approximations of Total Radioactivity NOTE! Every effort is made to ensure that all offluents fror Sequoyah are conducted such that all offsite Doso calculation Manual (ODcM)

Lower Limits of Detection (LLDs) are mot. Whencvor an analysis does not identify a radioisotopo, a "0.00E-01 Ci" is recorded for l the releano, This does not necessarily mean that no activity was rolossod for that particular radionuclido, but that the concentration was below tho ODCH and analysis LLDs. Hofer to Tables A and B for estimatos of those typical LLD valuce. l

a. Fission and Activation cason Airborno offluent gasoous activity-is continuously noittored and

-recorded. Additional grab samples from the shiold building, auxiliary building, service building, and condonsor vacuum oxhauals are taken and analyzed at least monthly to datormino the quantity of noblo gas activity rolcased for the month based on the avorago vont flowrates recorded for the samplo period. Also, nobio gas samples are collected and ovaluated for the shtold and ouxiliary buildings following ,

startup, shutdown, or rated thermal power chango excooding 15 porcent i wl'hin one hour (sampling only required if doso equivalent 1-131 concentration in the prinary coolant has increased moro than a factor of 3 and the nobio gas activity monitor shows that the containment activity has ircreased more than a factor of 3).

The quantity of nobio gases rolossed through the shield and auxiliary building oxhausto due to purging or venting of containment and rolonsos of waste gas decay tanks are also dolormined.

The total nobio nas activity released for the month is then dolormined ,

Lby summing all of the activity rolonsed from each vont for all -

-sampling porlods,.the activity colossed from purging or venting of 1 containment, and tho activity roloosed f rom wasto gas decay tank (s). t

b. lodinos and particulatos lodino and particulato activity is continuously samplod. Charcoal and particulato samples are taken from the shtold and auxiliary building exhausts and analyzed at least wookly to determino the total activity i

released from the plant based on the averato vont flowratos recorded for sampling period.

Also, particulate and charconi camplos aro taken from the auxiliary and shield building exhausts onco por 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 thonuti powor'chango excooding 15 parcont within ono hour. The quantity of iodino and particulato reloaced from occh vont during onch sampling period is then determined using the averano vont flowratos recorded for the sampling period and activity concentration.

The total particulate and iodino activity released for the month in then determined by summing all of the activity released from the shield and auxiliary building exhausto for all sampling portods.

Total samma isotopic activity concentrations are dotot1nined on each batch of liquid offluent prior to rolosso. The total activity of a ,

released batch is deturmined by summing each nuclide's concentration and na11tiplying by tho total volume discharged. The total activity colossed during a month to then determined by summing the activity T content of each batch discharged during the manth.

i (2) Continuous Holossos and periodic Continuous Releauco (Condensato resonorants, turbino building nump and steam generator blowdown)

Total gamma isotopic activity concentration la determined daily on a composite sample from the condensato system and turbino building sump and wookly for steam generator blowdown. The total activity of tho -

continuous rolosso is dolormined by summing each nuc11do's concentration and multiplying by the total volumo discharged. The total activity-relonsod during the month is then datot1nined by summing the activity content of each daily and wookly composito for the month. >

IN0pERABLE INSTHUMENTATION Pursuant to ODCH Section 1.3.1, the f ollowing information is provided concerning radioactivo effluent monitoring instrumentation which was inoperable for greater than 30 consecutivo days during the period July 1, 1991 through December 31, 1991.

Unit 2 shield bui131ng radiation monitor 2-RE-90-400 was inoperable from 7/8/91 to 8/28/91. In Januncy 1991 TVA changed out its post accident shield building radiation monitors with Sorrento Electronics wide range gas monitors.- In order'to' complete the radiatlon monitor nodification the now radiation monitors had to be removed from service for the removal of the old radiation monitors. .The physical work was completed in a timely manner and the radiation monitors returned to service. The required documentation and review extended the completion of the Work Plan and Unit 2 radiation uonitor was not considered operabic within the scheduled 30-day reporting limit.

In December 1991 during the performance of SI-198.3 it was determined that the flow instrumentation for the auxiliary _ building exhaust was out of calibration. The instrumentation was not out of servico (inoperablo) but

= 18% Jow. Since this instrumentation is used to evaluate monthly offsito dose for the auxiliary-building the 18% orror would result'in the following potential offsite dose errorst-Total _ Gamma Doso - 2.6%

Total Beta Doso - 2.6%
