ENCLOSURE 1 TENNESSEE VALEY AUTHORITY BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 RADIOLOGICAL IMPACT ASSESSMENT 2004 El-l Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 1. INTRODUCTION Potential doses to the "maximum exposed individual" and the population around Browns Ferry are calculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM). The methodology for determining plant releases for the reporting period used to estimate dose is specified in Sections 6 and 7 of the ODCM. Dispersion of radioactive effluents in the environment is estimated using meteorological data and river flow measured during the period. In this report, the doses resulting from releases 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 general public from the release of radioactive effluents.

These limits are set well below the Technical Specification limits which govern the concentrations of radioactivity and doses permissible in unrestricted areas. This ensures 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 effluents per 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 in particulate form, and radionuclides other than noble gases with half-lives

> 8 days released in gaseous effluents 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 effluents released 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 site boundary 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.E1-2 Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 M. DOSEACLTIN Estimated doses to Members of the Public are determined using computer models (the Gaseous Effluent Licensing Code. GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models are based on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113) for determining the potential dose to individuals and populations living in the vicinity of the plant The area around the plant is analyzed to determine the pathways through which the public may receive a dose. The doses calculated are a representation of the dose to a "maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maximum values to ensure conservative reporting data. Many of these 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: direct radiation 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 the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation 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 radwaste building, the reactor building, and the stack.Releases from the turbine building are considered ground-level releases.

The ground-level Joint Frequency Distribution (JFD) is derived from windspeeds and directions measured 10 meters above ground and from the vertical temperature difference between 10 and 45 meters, and are presented for each quarter in Tables 10, 11, 12, and 13.Releases from the radwaste and reactor buildings are considered split-level releases.

Portions of the release are treated as ground-level while other portions are considered elevated depending on the ratio of the vertical exit velocity to the horizontal wind speed. The split-level dispersion approach is implemented using a model that requires two complete quarterly JFDs for each effluent vent, one for the ground-level releases and one for the elevated releases.

The ground-level portion of the split-level JWD is based on wind speeds and directions measured 10 meters above ground-level and from the vertical temperature difference between 10 and 45 meters. The elevated portion of the split-level JFD is based on wind speeds and direction measurements at the 45 meter level and the vertical temperature difference between 45 and 91 meters. Both of 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 on wind directions and wind speeds measured at 91 meters and the vertical temperature difference between 45 and 91 meters, and are given for each quarter in Tables 22, 23, 24, and 25.El-3 Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 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 are calculated for each release point using the appropriate levels of meteorological data. A quarterly JFD gives the percentage of the time that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a given stability class A through G. The wind speeds are divided into nine wind speed ranges. Calms are distributed by direction in proportion to the distribution of noncalm wind directions less than 1.6 m/s (3.5 mph). Stability classes are detennined from the vertical temperature difference between two measurement levels.The generally open terrain around BFN does not cause any significant effects on the transport and dispersion of gaseous effluents from the plant. Within 30 kilometers of BEFN, the terrain is mostly gently rolling 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 on transport and dispersion in the immediate vicinity of BFN during periods of winds with a southerly component, overcast skies, and relatively high wind speeds. Also, the lower layer (1045 meters) stability class tends to be more stable. However, during this infrequent condition, dose estimates will be conservative.

External Exposure Dose Dose calculated for maximum external air dose (gamma-air and beta-air ) are made for points at and beyond the 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 the nearest 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, ground contamination, and ingestion pathways.

The ingestion pathway is further divided into three possible contributing pathways:

ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables.

Doses from applicable pathways are calculated for each receptor location identified in the most recent land use survey. 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 commercial preparation and vegetable ingestion is included only for those locations where a garden was identified.

To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest unrestricted area boundary location is added to each identified receptor.

For ground contamination, the dose added to the organ dose being calculated is the total body dose calculated for that location, i.e., it is assumed that the dose to 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 Tables 1, 2, 3, and 4.El-4 Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 V. DS ES For liquid effluents, the public can be exposed to radiation from three sources: the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactive material deposited on the river shoreline sediment (recreation).

The concentration of radionuclides in the Tennessee River are calculated by a computer model which uses measured hydraulic data downstream of BFN. Parameters used to determine the doses are based on guidance 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 to estimate 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 effluents are continuous.

When necessary, liquid releases from BFN, located at Tennessee River Mile 294, are made through diffusers which extend into the Tennessee River. It is assumed that releases to the river through these diffusers will initially be entrained in one-fifth of the water which flows past the plant. The QWATA code makes the assumption that this mixing condition holds true until the water is completely mixed at the first 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 maximum potential 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 the consumption of fish caught anywhere between the plant and the first downstream dam. The maximum exposed individual dose from drinking water is assumed to be that calculated at the nearest downstream public water supply (West Morgan -East Lawrence (WELL)]. This could be interpreted as indicating that the maximum exposed individual, as assumed for liquid releases from Browns Ferry, is an individual who obtains all of his drinking water at WMEL, consumes fish caught from the Tennessee River between BFN and Wheeler Dam, and spends 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per year on the shoreline just downstream of the plant's release point. Doses calculated for the maximum exposed individual due to liquid effluents for each quarter in the period are presented in Tables 5, 6, 7, and 8, along with the average river flows past the plant site for the periods.VI. POPULATION DOSES Population doses due to airborne effluents are calculated for an estimated 778,266 persons living within a 50-mile radius of the plant site. Doses from external pathways and inhalation are based on the 50-mile human population distribution.

Ingestion population doses are calculated assuming that each individual consumed 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 River population.

Water ingestion population doses are calculated using actual population figures for downstream public water supplies.

Fish ingestion population doses are calculated assuming that all sport fish caught in the Tennessee River are consumed by the Tennessee River population.

Recreation population doses are calculated 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.El-S Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 VII. OFFSITE DIRECT RADIATION DOSE External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployed around BFN as part of the offsite Radiological Environmental Monitoring Program (REMP). The quarterly gamma radiation levels determined from these TLDs during this reporting period averaged approximately 17 mrem/quarter at onsite (at or near the site boundary) stations and approximately 14.75 mrem/quarter at offsite stations or approximately 2.3 mrem/quarter higher onsite than at offsite stations.

This difference is consistent with levels measured for pre-operation and construction phases of TVA nuclear plants where the average radiation levels onsite were generally 2-6 mrem/quaxter higher than 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 other undetermined influences.

Fluctuations in natural background dose rates and in TLD readings tend to mask any small increments which may be due to plant operations.

Thus, there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents.

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 of the public in the site boundary.

This review assumed that onsite TVA employees engaged in work activities not associated with nuclear power electric generation were considered as members of the public. The dose to a member of the public consists of the sum of dose commitments from effluent releases as well as any direct radiation dose. The effluent dose commitment is negligible compared to the direct radiation dose.The direct radiation dose was determined from area TLDs located onsite. It consisted of gamma dose from 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 background and 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 direct radiation dose while in the site boundary.

It can be concluded that the dose limit for a member of the public inside the site boundary as specified in 10 CFR 20.1301 was not exceeded.El-6 Radiological Impact Assessment Browns Ferry Nuclear Plant January -December 2004 IX TOTAL DOSE To determine compliance with 40 CFR 190, annual total dose contributions to the maximum exposed individual 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 conservatively calculated by summing the following doses: the total body air submersion dose for each quarter, the critical organ dose (for any organ other than the thyroid) from airborne effluents for each quarter from ground contamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, the maximum organ dose (for any organ other than the thyroid) from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the REMP. This dose is compared to the 40 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 the following doses: the total body air submersion dose for each quarter, the thyroid dose from airborne effluents for each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the REMP. This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance.

The flow rate of the stack is continuously monitored and the building vent effluent flow rates are calculated once a shift based on the configuration of operating exhaust fans. The vent flow is calculated for each release. Gas grab samples of the stack are taken and analyzed weekly. Gas grab samples of in-service vents are taken and analyzed monthly. The specific noble gas activity concentrations and total volume of the gases 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 each release point.E3 -3 EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT YEAR 2004 ml. Measurements and Approximations of Total Radioactivity (continued)

B. lodines and Particulates I. lodines and particulates are continuously sampled on impregnated charcoal filters and particulate filters, respectively.

The charcoal and particulate samples are replaced at least weekly and analyzed to determine specific activity concentrations.

The specific activity concentrations and vent flow rate data are used weekly to verify that release rate limits were not exceeded.

The specific activity concentrations and total volume of gaseous effluent are used on a monthly basis to determine the total curies of each particulate and iodine released during the month.2. The gross alpha concentration is determined by analysis of a monthly particulate filter composite sample and strontium

-89 and -90 are determined by analysis of a quarterly particulate filter composite sample for each release point.C. Liquid Effluents 1. The gamma ray emitting radionuclide concentrations are determined for each batch by gamma ray spectroscopy analysis of a grab sample. The allowable release rate is calculated for each batch based upon the known dilution flow. The flow rate of the liquid effluent is continuously monitored and the total volume released in each batch is determined.

The total gamma activity released in each batch is determined by multiplying the radionuclide concentrations by the total volume discharged.

The total gamma activity released during the month is then determined by summing the gamma activity content of each 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.

SUMMARY

OF ABNORMAL/UNPLANNED RELEASES 2004 The release of radioactive material to the environment from Browns Feny has been a small fraction of the 10 CFR 20 Appendix B and 10 CFR 50 Appendix I limits. There were no limits exceeded as specified in 10 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 compensatory measures.There was one missed sample period for Unit 3 reactor zone (mixed mode) gaseous effluent iodines and particulates from April 27, 2004 at 0254 hours0.00294 days <br />0.0706 hours <br />4.199735e-4 weeks <br />9.6647e-5 months <br /> until May 4,2004 at 0358 hours0.00414 days <br />0.0994 hours <br />5.919312e-4 weeks <br />1.36219e-4 months <br />. The charcoal and particulate 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 (sample prior to the missing filter set) and May 11, 2004 (sample after the missing filter set) were compared.

Both filter 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. The April 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).E3 -20 ENCL "SURE 4 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN)UNITS 1, 2, AND 3 INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT 2004 E4 -1 INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT 2004 This report complies with Browns Ferry Nuclear Plant Offsite Dose Calculation Manual (ODCM) Sections 1/2.1.1 and 1/2.1.2. The ODCM requires the exertion of best efforts to return inoperable instruments to operable status within 30 days. Failure to return such instruments to an operable status within the prescribed interval 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 effluent monitoring instrumentation out of service for greater than 30 days; however, two gaseous effluent monitors were out of service for greater than 30 days. The Unit I Reactor/Turbine/Refuel Building Ventilation Monitor (I-RM-90-250) was inoperable from May 12, 2004 at 2150 hours0.0249 days <br />0.597 hours <br />0.00355 weeks <br />8.18075e-4 months <br /> until July 26, 2004 at 1530 hours0.0177 days <br />0.425 hours <br />0.00253 weeks <br />5.82165e-4 months <br /> and the Unit 3 Reactortlurbine/Refuel Building Ventilation Monitor (3-RM-90-250) was inoperable from November 19, 2004 at 1706 hours0.0197 days <br />0.474 hours <br />0.00282 weeks <br />6.49133e-4 months <br /> through the end of the reporting period. Monitor 3-RM-90-250 was retuned to service on February 1, 2005 at 1830 hours0.0212 days <br />0.508 hours <br />0.00303 weeks <br />6.96315e-4 months <br />. Both monitors' flow measuring systems were inoperable.

The flow systems were obsolete and could not be replaced.

New flow control systems were designed and installed.

All compensatory measures were completed as required.ODCM Section 1.1.2 requires the radioactive gaseous effluent monitoring instruments alarm/trip setpoints be set in accordance with ODCM section 7.2 to ensure ODCM control limits are not exceeded.

During a design review of the ten building gaseous effluent radiation monitoring instruments, it was discovered that the setpoints were set a factor of 60 low since installation in 1991. This included the three Reactor/TurbinelRefuel Building Ventilation Monitors (1, 2 and 3-RM-90-250), the six Turbine Building Ventilation Monitors (1, 2, and 3-RM-90-249 and 1, 2, and 3-RM-90-251) and the Radwaste Building Ventilation Monitor (0-RM-90-252).

Monitor flows were recorded in units of cc/sec instead of cc/min as required by the vendor firmware.

This resulted in the monitors reading a factor of 60 low. All affected monitors were placed in an inoperable status and compensatory measures were implemented until flow readings could be corrected.

A review of data generated since 1991 was completed, and it was determined that 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 these monitors' effluent streams were isolated.

Therefore, these monitors are not included in this report.E4-2
