1. INTRODUCTION

Potential doses to the "maximum exposed individual" and the population around Browns Ferry arecalculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM). Themethodology for determining plant releases for the reporting period used to estimate dose is specified inSections 6 and 7 of the ODCM. Dispersion of radioactive effluents in the environment is estimated usingmeteorological data and river flow measured during the period. In this report, the doses resulting fromreleases are described and compared to limits established for Browns Ferry.

[E. DOSE LIM1TS

The ODCM specifies limits for the release of radioactive effluents, as well as limits for doses to the generalpublic from the release of radioactive effluents. These limits are set well below the Technical Specificationlimits which govern the concentrations of radioactivity and doses permissible in unrestricted areas. Thisensures that radioactive effluent releases are As Low As Reasonably Achievable.

The air dose limits in areas at and beyond the Site Boundary due to noble gases released in gaseous effluentsper unit are:

< 5 nirad per quarter and< 10 mnrad per year for gamma radiation.

-and-< 10 mrad per quarter and

< 20 mrad per year for beta radiation.

The dose limits to a Member of the Public in an unrestricted area from radioiodines, radioactive materials inparticulate form, and radionuclides other than noble gases with half-lives > 8 days released in gaseouseffluents for each unit are:

< 7.5 mrem per quarter and< 15 mrem per year to any organ.

The dose or dose commitment to a Member of the Public from radioactive material in liquid effluentsreleased to unrestricted areas are:

< 1.5 mrem per quarter and<3 mrem per year to the total body,

-and -

< 5 mrem per quarter and< 10 mirem per year to any organ.

The limit for the total effective dose equivalent to an individual Member of the Public inside the siteboundary is:

100 mrem per year.

The EPA limits for, total dose to any Member of the Public in the vicinity of a nuclear power plant,established in the Environmental Dose Standard of 40 CFR 190, are:

• 25 mrem per year to the whole body,< 75 mrem per year to the thyroid,

-and-* 25 mrem per year to any other organ.

M. DOSEACLTIN

Estimated doses to Members of the Public are determined using computer models (the Gaseous EffluentLicensing Code. GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models arebased on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113) for determining thepotential dose to individuals and populations living in the vicinity of the plant The area around the plant isanalyzed to determine the pathways through which the public may receive a dose. The doses calculated area representation of the dose to a "maximum exposed individual." Some of the factors used in thesecalculations (such as ingestion rates) are maximum values to ensure conservative reporting data. Many ofthese factors are obtained from NUREGICR-1004. The values chosen will tend to overestimate the dose.The expected dose to actual individuals is lower. The calculated doses are presented in Tables 1, 2. 3, 4. 5,6, 7, 8, and 9.

IV. DOSES FROM AIRBORNE EFFLUENTS

For airborne effluents, Members of the Public can be exposed to radiation from several sources: directradiation from the radioactivity in the air, direct radiation from radioactivity deposited on the ground,inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited from theatmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere ontovegetation and subsequently consumed by milk and beef animals.

Airborne Release Points

There are four monitored release points from Browns Ferry Nuclear Plant the turbine building, the radwastebuilding, the reactor building, and the stack.

Releases from the turbine building are considered ground-level releases. The ground-level Joint FrequencyDistribution (JFD) is derived from windspeeds and directions measured 10 meters above ground and fromthe vertical temperature difference between 10 and 45 meters, and are presented for each quarter in Tables10, 11, 12, and 13.

Releases from the radwaste and reactor buildings are considered split-level releases. Portions of the releaseare treated as ground-level while other portions are considered elevated depending on the ratio of thevertical exit velocity to the horizontal wind speed. The split-level dispersion approach is implemented usinga model that requires two complete quarterly JFDs for each effluent vent, one for the ground-level releasesand one for the elevated releases. The ground-level portion of the split-level JWD is based on wind speedsand directions measured 10 meters above ground-level and from the vertical temperature difference between10 and 45 meters. The elevated portion of the split-level JFD is based on wind speeds and directionmeasurements at the 45 meter level and the vertical temperature difference between 45 and 91 meters. Bothof these JFDs are given for each quarter in Tables 14, 15, 16, 17, 18, 19, 20, and 21.

Releases from the stack are considered to be elevated releases. The JFDs for elevated releases are based onwind directions and wind speeds measured at 91 meters and the vertical temperature difference between 45and 91 meters, and are given for each quarter in Tables 22, 23, 24, and 25.

El-3


Meteorolonical Data

Meteorological variables at BFN are measured continuously. Measurements collected include wind speed,wind direction, and temperature at heights of 10, 45, and 91 meters above the ground. Quarterly JFDs arecalculated for each release point using the appropriate levels of meteorological data. A quarterly JFD givesthe percentage of the time that the wind is blowing out of a particular upwind compass sector in a particularrange of wind speeds for a given stability class A through G. The wind speeds are divided into nine windspeed ranges. Calms are distributed by direction in proportion to the distribution of noncalm winddirections less than 1.6 m/s (3.5 mph). Stability classes are detennined from the vertical temperaturedifference between two measurement levels.

The generally open terrain around BFN does not cause any significant effects on the transport anddispersion of gaseous effluents from the plant. Within 30 kilometers of BEFN, the terrain is mostly gentlyrolling hills (30-60 meters). Between 30 and 80 kilometers the hills become larger to the north and south,and mountainous to the east and northeast. The Tennessee River/Wheeler Lakle may have a minor effect ontransport and dispersion in the immediate vicinity of BFN during periods of winds with a southerlycomponent, overcast skies, and relatively high wind speeds. Also, the lower layer (1045 meters) stabilityclass tends to be more stable. However, during this infrequent condition, dose estimates will beconservative.

External Exposure Dose

Dose calculated for maximum external air dose (gamma-air and beta-air ) are made for points at and beyondthe unrestricted area boundary as described in the BFN ODCM. The highest of these doses is then selected.

Submersion Dose

External doses to the skin and total body, due to submersion in a cloud of noble gases, are calculated for thenearest residence in each sector. The residence with the highest dose is then selected from all sectors.

Organ Dose

Dose to an organ due to releases of airborne effluents are estimated for the inhalation, groundcontamination, and ingestion pathways. The ingestion pathway is further divided into three possiblecontributing pathways: ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables. Dosesfrom applicable pathways are calculated for each receptor location identified in the most recent land usesurvey. To determine the maximum organ dose, the doses from the pathways are summed for each receptor.For the ingestion dose, however, only those pathways that exist for each receptor are considered in the sum,e.g., milk ingestion doses are included only for locations where milk was consumed without commercialpreparation and vegetable ingestion is included only for those locations where a garden was identified. Toconservatively account for beef ingestion, a beef ingestion dose equal to that for the highest unrestricted areaboundary location is added to each identified receptor. For ground contamination, the dose added to theorgan dose being calculated is the total body dose calculated for that location, i.e., it is assumed that the doseto an individual organ is equal to the total body dose.

The maximum organ dose, thyroid dose, and total body dose from airborne effluents are presented in Tables1, 2, 3, and 4.

V. DS ES

For liquid effluents, the public can be exposed to radiation from three sources: the ingestion of water fromthe Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure fromradioactive material deposited on the river shoreline sediment (recreation).

The concentration of radionuclides in the Tennessee River are calculated by a computer model which usesmeasured hydraulic data downstream of BFN. Parameters used to determine the doses are based onguidance given by the NRC (in Regulatory Guides 1.109) for maximum ingestion rates, exposure times, etc.Wherever possible, parameters used in the dose calculation are site specific. The models that are used toestimate doses, as well as the parameters input to the models, are described in detail in the BFN ODCM.

kiguid Release Points and River Data

Radionuclide concentrations in the Tennessee River are calculated assuming that releases in liquid effluentsare continuous. When necessary, liquid releases from BFN, located at Tennessee River Mile 294, are madethrough diffusers which extend into the Tennessee River. It is assumed that releases to the river throughthese diffusers will initially be entrained in one-fifth of the water which flows past the plant. The QWATAcode makes the assumption that this mixing condition holds true until the water is completely mixed at thefirst downstream dam (Wheeler Dam), at Tennessee River Mile 283.0.

Doses are calculated for locations within a 50 mile radius downstream of the plant site. The maximumpotential recreation dose is calculated for a location inmediately downstream from the plant's release point.The maximum exposed individual dose from ingestion of fish is assumed to be that calculated for theconsumption of fish caught anywhere between the plant and the first downstream dam. The maximumexposed individual dose from drinking water is assumed to be that calculated at the nearest downstreampublic water supply (West Morgan - East Lawrence (WELL)]. This could be interpreted as indicating thatthe maximum exposed individual, as assumed for liquid releases from Browns Ferry, is an individual whoobtains all of his drinking water at WMEL, consumes fish caught from the Tennessee River between BFNand Wheeler Dam, and spends 500 hours per year on the shoreline just downstream of the plant's releasepoint. Doses calculated for the maximum exposed individual due to liquid effluents for each quarter in theperiod are presented in Tables 5, 6, 7, and 8, along with the average river flows past the plant site for theperiods.

VI. POPULATION DOSES

Population doses due to airborne effluents are calculated for an estimated 778,266 persons living within a50-mile radius of the plant site. Doses from external pathways and inhalation are based on the 50-milehuman population distribution. Ingestion population doses are calculated assuming that each individualconsumed milk, vegetables, and meat produced within the sector in which the individual resides.

Population doses due to liquid effluents are calculated for the entire downstream Tennessee Riverpopulation. Water ingestion population doses are calculated using actual population figures for downstreampublic water supplies. Fish ingestion population doses are calculated assuming that all sport fish caught inthe Tennessee River are consumed by the Tennessee River population. Recreation population doses arecalculated using historical recreational data on the number of shoreline visits at downstream locations.

Population doses calculated for airborne and liquid effluents are presented in Tables 1, 2, 3, 4, 5, 6, 7, and 8.

VII. OFFSITE DIRECT RADIATION DOSE

External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployedaround BFN as part of the offsite Radiological Environmental Monitoring Program (REMP). Thequarterly gamma radiation levels determined from these TLDs during this reporting period averagedapproximately 17 mrem/quarter at onsite (at or near the site boundary) stations and approximately 14.75mrem/quarter at offsite stations or approximately 2.3 mrem/quarter higher onsite than at offsitestations. This difference is consistent with levels measured for pre-operation and construction phases ofTVA nuclear plants where the average radiation levels onsite were generally 2-6 mrem/quaxter higherthan the levels offsite. This may be attributable to natural variations in environmental radiation levels,earth moving activities onsite, the mass of concrete employed in the construction of the plants, or otherundetermined influences. Fluctuations in natural background dose rates and in TLD readings tend tomask any small increments which may be due to plant operations. Thus, there was no identifiableincrease in dose rate levels attributable to direct radiation from plant equipment and/or gaseouseffluents.

VM. DOSE TO A NIEMEBER OF THE PUBLIC INSIDE THE SITE BOUNDARY

Pursuant to ODCM section 7.7.5, a review was performed to determine the highest dose to a member ofthe public in the site boundary. This review assumed that onsite TVA employees engaged in workactivities not associated with nuclear power electric generation were considered as members of thepublic. The dose to a member of the public consists of the sum of dose commitments from effluentreleases as well as any direct radiation dose. The effluent dose commitment is negligible compared tothe direct radiation dose.

The direct radiation dose was determined from area TLDs located onsite. It consisted of gamma dosefrom the plume, ground contamination and from equipment sources (i.e., tanks, turbine shine,radioactive material storage areas, etc.). The highest direct radiation dose accounting for backgroundand occupancy was 4.8 mrem during 2004.

The total annual dose commitment to the member of the public for 2004 is 4.8 mrem; the directradiation dose while in the site boundary. It can be concluded that the dose limit for a member of thepublic inside the site boundary as specified in 10 CFR 20.1301 was not exceeded.

IX TOTAL DOSE

To determine compliance with 40 CFR 190, annual total dose contributions to the maximum exposedindividual from BFN radioactive effluents and all other nearby uranium fuel cycle sources are considered.

The annual dose to any organ other than thyroid for the maximum exposed individual is conservativelycalculated by summing the following doses: the total body air submersion dose for each quarter, the criticalorgan dose (for any organ other than the thyroid) from airborne effluents for each quarter from groundcontamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, themaximum organ dose (for any organ other than the thyroid) from liquid effluents for each quarter, and anyidentifiable increase in direct radiation dose levels as measured by the REMP. This dose is compared to the40 CFR 190 limit for total body or any organ dose (other than thyroid) to determine compliance.

The annual thyroid dose to the maximum exposed individual is conservatively estimated by summing thefollowing doses: the total body air submersion dose for each quarter, the thyroid dose from airborne effluentsfor each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liquideffluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by theREMP. This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance.

Total dose from the fuel cycle is presented in Table 9.

LRegplatory and BFN ODCM Limits

A. Fission and Activation Gases in Gaseous Effluent:

The release of fission and activation gases is regulated by the dose limits of 10 CFR 50Appendix I and BFN Offsite Dose Calculation Manual (ODCM). The air dose to areas at andbeyond the site boundary due to noble gases released in gaseous effluents per unit, shall belimited during any calendar quarter to • 5 millirad (mrad) for gamma radiation and < 10 rnradfor beta radiation; and during any calendar year to < 10 mrad for gamma radiation and < 20mrad for beta radiation.

B. Iodines and Particulates with Half-Lives Greater than Eight Days inGaseous Effluents.

The release of iodines and particulates in gaseous effluent is regulated by the dose limits of 10CFR 50 Appendix I and the BFN ODCM. The dose to a member of the public fromradioiodines, radioactive materials in particulate form, and radionuclides other than noble gaseswith half-lives greater than eight days in gaseous effluent released per unit to areas at andbeyond the site boundary shall be limited to any organ during any calendar quarter to < 7.5millirem (mrem), and during any calendar year to < 15 mrem.

C. Liquid Effluents

The release of radioactive liquid effluents is regulated by the dose limits of 10 CFR 50 AppendixI and the BFN ODCM. The doses or dose commitment to a member of the public fromradioactive materials in liquid effluents released from each unit to unrestricted areas shall belimited during any calendar quarter to < 1.5 mrem to the total body and <5 mrem to any organand during any calendar year to < 3 mrem to the total body and • 10 mrem to any organ.

II. Limitation on Dose Rate

A. Fission and Activation Gases in Gaseous Effluent:

1. The instantaneous release rate of fission and activation gases is based on the dose rate limitsof 10 CFR 20.1301 and the BFN ODCM. The dose rate at any time to areas at and beyondthe site boundary due to noble gases released in gaseous effluents from the site shall belimited to • 500 mrem per year to the total body and < 3000 mrem per year to the skdn.

2. Tho BFN ODCM Section 7.2 determines the maximum noble gas release rate.

B. lodines and Particulates with Half-Lives Greater than Eight Days in gaseous effluents.

1. The instantaneous release rate of particulates and iodines is regulated by the dose ratelimits of the BFN ODCM. The dose rate at any time to areas at and beyond the siteboundary, due to 1-1 31, 1-133, H-3 and particulates with greater than eight days half-livesreleased in gaseous effluents from the site, shall be limited to < 1500 mrem per year toany organ.

2. The BFN ODCM Section 7.3 determines the maximum particulate and iodine dose rates.

C. Liquid Effluents

1. The concentration of radionuclides in liquid effluents released at any time from the site tounrestricted areas shall be limited to the concentrations specified in 1O CFR 20.1001 -20.2402, Appendix B, Table 2, Column 2 for radionuclides other than dissolved orentrained noble gases.

2. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 J4Ci permilliliter (ml) total activity.

III. Measurements and Approximations of Total Radioactivy

A. Fission and Activation Gases:

1. Noble gases in the building vent and stack (elevated) gaseous effluents are continuouslymonitored. The flow rate of the stack is continuously monitored and the building venteffluent flow rates are calculated once a shift based on the configuration of operatingexhaust fans. The vent flow is calculated for each release. Gas grab samples of the stackare taken and analyzed weekly. Gas grab samples of in-service vents are taken andanalyzed monthly. The specific noble gas activity concentrations and total volume of thegases are used to calculate the total curies of noble gases released.

2. The tritium concentration is determined by the analysis of a monthly grab sample for eachrelease point.

E3 -3


ml. Measurements and Approximations of Total Radioactivity (continued)

B. lodines and Particulates

I. lodines and particulates are continuously sampled on impregnated charcoal filters andparticulate filters, respectively. The charcoal and particulate samples are replaced at leastweekly and analyzed to determine specific activity concentrations. The specific activityconcentrations and vent flow rate data are used weekly to verify that release rate limitswere not exceeded. The specific activity concentrations and total volume of gaseouseffluent are used on a monthly basis to determine the total curies of each particulate andiodine released during the month.

2. The gross alpha concentration is determined by analysis of a monthly particulate filtercomposite sample and strontium -89 and -90 are determined by analysis of a quarterlyparticulate filter composite sample for each release point.

C. Liquid Effluents

1. The gamma ray emitting radionuclide concentrations are determined for each batch bygamma ray spectroscopy analysis of a grab sample. The allowable release rate iscalculated for each batch based upon the known dilution flow. The flow rate of the liquideffluent is continuously monitored and the total volume released in each batch isdetermined. The total gamma activity released in each batch is determined by multiplyingthe radionuclide concentrations by the total volume discharged. The total gamma activityreleased during the month is then determined by summing the gamma activity content ofeach batch discharged during the month.

2. The gross alpha and tritium concentrations are measured on a monthly composite sample.The strontium -89 and -90 and iron -55 are measured on a quarterly composite sample.

D. The Radioactive Gaseous and Liquid Waste Monitoring Sampling and Analysis Program isspecified in ODCM Sections 1/2.2.1 and 1/2.2.2.

BROWNS FERRY NUCLEAR PLANTEFFLUENT AND WASTE DISPOSAL ANNUAL REPORTSUMMARY OF ABNORMAL/UNPLANNED RELEASES

2004

The release of radioactive material to the environment from Browns Feny has been a small fraction of the10 CFR 20 Appendix B and 10 CFR 50 Appendix I limits. There were no limits exceeded as specified in10 CFR 20 Appendix B and 10 CFR 50 Appendix 1.

No abnormal gaseous or liquid releases occurred in 2004.

During the reporting period, January I through December 31, 2004, there were no missed compensatorymeasures.

There was one missed sample period for Unit 3 reactor zone (mixed mode) gaseous effluent iodines andparticulates from April 27, 2004 at 0254 hours until May 4,2004 at 0358 hours. The charcoal andparticulate filter set was found to be missing during the weekly change of the filters on May 04, 2004(Problem Evaluation Report (PER) 60670). Activity from the filters removed on April 27, 2004 (sampleprior to the missing filter set) and May 11, 2004 (sample after the missing filter set) were compared. Bothfilter sets contained only Cs-137. The highest concentration was from the set removed on April 27, 2004.The Unit 3 reactor had completed a refueling outage in April and activity was trending down. TheApril 27, 2004 concentration was included for the missing filter set.

In calendar year 2004, Browns Ferry had no changes to the radwaste system or the Process Control Program(PCP).

INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT2004

This report complies with Browns Ferry Nuclear Plant Offsite Dose Calculation Manual (ODCM) Sections1/2.1.1 and 1/2.1.2. The ODCM requires the exertion of best efforts to return inoperable instruments tooperable status within 30 days. Failure to return such instruments to an operable status within the prescribedinterval requires a description in the Annual Radioactive Effluent Release Report.

During the reporting period, January I through December 31, 2004, there were no radioactive liquid effluentmonitoring instrumentation out of service for greater than 30 days; however, two gaseous effluent monitorswere out of service for greater than 30 days. The Unit I Reactor/Turbine/Refuel Building VentilationMonitor (I-RM-90-250) was inoperable from May 12, 2004 at 2150 hours until July 26, 2004 at 1530 hoursand the Unit 3 Reactortlurbine/Refuel Building Ventilation Monitor (3-RM-90-250) was inoperable fromNovember 19, 2004 at 1706 hours through the end of the reporting period. Monitor 3-RM-90-250 wasretuned to service on February 1, 2005 at 1830 hours. Both monitors' flow measuring systems wereinoperable. The flow systems were obsolete and could not be replaced. New flow control systems weredesigned and installed. All compensatory measures were completed as required.

ODCM Section 1.1.2 requires the radioactive gaseous effluent monitoring instruments alarm/trip setpointsbe set in accordance with ODCM section 7.2 to ensure ODCM control limits are not exceeded. During adesign review of the ten building gaseous effluent radiation monitoring instruments, it was discovered thatthe setpoints were set a factor of 60 low since installation in 1991. This included the threeReactor/TurbinelRefuel Building Ventilation Monitors (1, 2 and 3-RM-90-250), the six Turbine BuildingVentilation Monitors (1, 2, and 3-RM-90-249 and 1, 2, and 3-RM-90-251) and the Radwaste BuildingVentilation Monitor (0-RM-90-252). Monitor flows were recorded in units of cc/sec instead of cc/min asrequired by the vendor firmware. This resulted in the monitors reading a factor of 60 low. All affectedmonitors were placed in an inoperable status and compensatory measures were implemented until flowreadings could be corrected. A review of data generated since 1991 was completed, and it was determinedthat no release rate limit was exceeded during the period the setpoints were non-conservative.

Some effluent monitors and flow instrumentation were placed in "out-of-service" status because thesemonitors' effluent streams were isolated. Therefore, these monitors are not included in this report.
