UPDATE TO THE ANNUAL RADIOLOGICAL EFFLUENT REPORT (ARER)
JANUARY THROUGH DECEMBER 2001 This letter provides an updated 2001 ARER including a corrected Enclosure 3, page 12, the original ARER was sent to NRC on April 16, 2001.
This updated ARER also covers the period from January through December 2001, and supersedes the previous ARER.
During a follow-up review of the 2001 ARER, it was identified that Np-239 was erroneously listed as a particulate of the gaseous ground release in the Effluent and Waste Disposal Annual Report portion (Enclosure 3 on Page 12).
As such, this particulate has now been removed from the report.
This erroneous inclusion of Np-239 as a particulate did not have any significant effect on the total curies released from BFN in 2001.
There are no commitments contained in this letter.

Rad;nogical Impact Assessment r rowns Ferry Nuclear Plant January - December 2001 I. 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 methodolog for determining plant releases for the reporting penod 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 lihmts established for Browns Ferry.
II. DOSE LIMITS The ODCM specifies limits for the release of radioacuve 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 lirmts in areas at and beyond the Site Boundary due to noble gases released in gaseous effluents per unit are:
<5 mrad per quarter and
< 10 mrad 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 mrem 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.¢ 4 100 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.

Radiologic-t lmr
` -kssessment Browns 'c.rry :,uclear Plant January - December 2001 I11. DOSE CALCULATIONS 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 deternuning the potential dose to indi*iduals 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 NUREG/CR-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, ertical 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 ertical 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 JFD 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 2 1.
Releases from the stack are considered to be elevated releases. The JFDs for elevated releases are based on
'ýimd directions and wind speeds measured at 91 meters and the vertical temperature difference between 45 and 91 metek, and are given for each quarter in Tables 22, 23, 24, and 25.

Radiological Impact Assessment Browns Ferry Nuclea ?':
January - December 2001 Meteorological Data Meteorological variables at BFN are measured continuously. Measurements collected include wind speed, wvind directon, and temperature at heights of 10, 45, and 91 meters aboNe the ground. Quarterly.FDs are calculated for each release point using the appropriate levels of meteorological data. A quarterly LFD 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 %ýind 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 determined 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 BFN, 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 Lake 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 (10-45 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.
Orzan 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.
i e.. 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 contanunation, 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.

Radiological Impact Assessment Browns Ferry Nuclear Plant January - December 2001 V. DOSES FROM LIQUID EFFLUENTS For liquid effluents, the public can be exposed to radiation from three sources-the ingestion of ater from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactme material deposited on the river shoreline sediment (recreauon).
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 Liquid 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 immediately 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 dnnking water is assumed to be that calculated at the nearest downstream public water supply [West Morgan - East Lawrence (WMEL)I. This could be interpreted as indicating that the maximum e.xposed individual, as assumed for liquid releases from Browns Ferry, is an individual who obtains all of his dnnking 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 627.000 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 distnbution. 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 waterisupplies. 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-5
Radiological Impact Assessment Browns Ferry Nuclear Plant January - December 2001 VII. OFFSITE DIRECT RADIATION DOSE External gamma radiation levels were measured by thermolurmnescent dosimeters (TLDs) deployed around BFN as part of the offsite Radiological Environmental Monitoring Program (REMP) The quarterly gamma radiation levels deterrmned from these TLDs during this reporting period averaged approximately 15 5 mrem/quarter at onsite (at or near the site boundary) stations and approximately 13 25 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/quarter 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.
VIII. DOSE TO A MEMBER OF THE PUBLIC INSI]DE 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 dose from effluent releases consists of inhalation, ingestion, and submersion doses. The inhalation dose commitment assumes that site occupancy factors are sufficiently low to compensate for the increase in the atmospheric dispersion above that for the site boundary. The ingestion dose commitments use the pathways and calculated values described previously for beef, milk, and garden vegetable ingestion as nell as the dose commitments from liquid effluents The submersion dose is an external radiation dose commitment from gaseous effluents.
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 7.3 mrem dunng 2001.
The total annual dose is the sum of the direct radiation dose (7 3 mrem) and the effluent dose commitment (2.5E-02 torem) or 7.3 mrem. It can be concluded that the dose lirmt for a member of the public inside the site boundary as specified in 10 CFR 20 1301 was not exceeded.

'diological Impact Assessment Browns Ferry Nuclear Plant January - December 2001 LX. TOTAL DOSE To determine compliance wvith 40 CFR 190, annual total dose contributions to the maximum exposed indi*idual 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 sumnnung the follovwng 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 lihmt for thyroid dose to determine compliance.
Total dose from the fuel cycle is presented in Table 9.

Measurements and Approximations of Total Radioactivity A.
Fission and Activation Gases:
- 1. Noble gases in the building vent and stack (elevated) gaseous effluents are continuously monitored. 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.

Measurements and Approximations of Total Radioactivity (continued)
B.
lodines and Particulates
- 1.
Iodines 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 I.
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.
The Radioactive Gaseous and Liquid Waste Monitoring Sampling and Analysis Program is specified in ODCM Sections 1/2.2.1 and 1/2.2.2.

UNITS 1, 2, AND 3 INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT 2001 E4-1
INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT 2001 This report is to comply with Browns Ferry Nuclear Plant Offsite Dose Calculation Manual (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, 2001, there were no radioactive liquid or gaseous effluent monitoring instrumentation out of service for greater than 30 days.
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.
