INTRODUCTION Radiological Impact Assessment Browns Ferry Nuclear Plant January - June 1993 Page 1 of 66 Potential doses to maximum individuals and the population around Browns Ferry are calculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM).
Measured plant releases for the reporting period are used to estimate these doses.
Dispersion of radioactive effluents in the environment is estimated using meteorological data and riverflow data measured during the period.
In this report, the doses resulting from releases are described and compared to limits established for Browns Ferry.
DOSE LIMITS The ODCM specifie 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 NRC 10 CFR 20 limits which govern the concentrations of radioactivity and exposures permissible in unrestricted areas.
This ensures that radioactive effluent releases are As Low As Reasonably Achievable.
The limits for doses at or beyond the site boundary from airborne noble gases releases are:
Less than or equal to 5 mrad per quarter and 10 mrad per year (per reactor unit) for gamma radiation,
- and-Less than or equal to 10 mrad per quarter and 20 mrad per year (per reactor unit) for beta radiation.
The limitfor the dose to a member ofthe general public at or beyond the site boundary from iodines and particulates released in airborne effiuents is:
Less than or equal to 7.5 mrem per quarter and 15 mrem per year (per reactor unit) to any organ.
The limit for doses to a member of the general public from radioactive material in liquid effluents released to unrestricted areas, is:
Less than or equal to 1.5 mrem per quarter and 3 mrem per year (per reactor unit) to the total body,
- and-Less than or equal to 5 mrem per quarter and 10 mrem per year (per reactor unit) to any organ The EPA limits fortotal dose to the public in the vicinityof a nuclear power plant, established in the Environmental Dose Standard of 40 CFR 190, are:
Less than or equal to 25 mrem per year to the total body, Less than or equal to 75 mrem per year to the thyroid,
-and-Less than or equal to 25 mrem per year to any other organ.

Radiological Impact Assessment Browns Ferry Nuclear Plant January - June 1993 DOSE CALCULATIONS Estimated doses to 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 vicinityof 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 ofthe factors used in these calculations (such as ingestion rates) are maximum values.
Many of these factors are obtained from NUREG/CR-1004. The values chosen willtend to overestimate the dose to this "maximum" person.
The expected dose to actual individuals is lower.
The calculated doses are presented in Tables 1A, 1B,2A,2B and 3.
DOSES FROM AIRBORNE EFFLUENTS For airborne effluents, 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 which is then eaten by milk and beef animals.
Airborne Re/ease Points There are four routine 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 46 meters, and is presented in Tables 4A and 48.
Releases from the radwaste and reactor buildings are considered split-level releases.
Portions of the release are treated as elevated while other portions are considered ground-level 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 elevated releases and one for the ground-level 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 46 meters.
The elevated portion of the split-level JFD is based on wind speeds and direction measurements at the 46-meter level and the vertical temperature difference between 46 and meters.
Both of these JFDs are given in Tables 5A, 5B, 5E, and 5F.
Releases from the stack are considered to be elevated-level releases.
The JFDs for elevated releases are based on wind directions and wind speeds measured at 91 meters and the vertical temperature difference between 46 and 91 meters, and are given in Tables 6A and 6B.
Meteorolo ical Data Meteorological variables at Browns Ferry are measured continuously. Measurements collected include wind speed, wind direction, and temperature at heights of 10, 46 and 91 meters above the ground. Quarterly joint frequency distributions (JFDs) are calculated for each release point using the appropriate levels of meteorological data. AJoint frequency distribution gives the percentage of the time in a quarter that the wind is blowing out of a particular upwind compass
Radiological Impact Assessment Browns Ferry Nuclear Plant January - June 1993 Page 3 of 66 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. Cairns are distributed by direction in proportion to the distribution of noncalm wind directions less than 0.7 m/s (1.5 mph).
Stability classes are determined from the vertical temperature difference between two measurement levels.
The generally open terrain around BFN is not believed to 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 vicinityof BFN during periods of winds with a southerly component, overcast skies, and relatively high wind speeds.
Then, the lower layer (10-46 meters) stability class tends to be more stable than would be expected.
However, during this infrequent condition, dose estimates will be conservative.
Ex/erne/ Ex osure Dose Dose estimates for maximum external air exposures (gamma-air and beta-air doses) are made for points at and beyond the site boundary as described in the BFN ODCM.
Submersion Dose External doses to the skin and total body, due to submersion in a cloud of noble gases, are estimated for the nearest residence in each sector.
~Or an Dose Doses to organs due to releases of airborne effluents are estimated for the inhalation, ground contamination, and ingestion pathways.
The ingestion pathway is further divided into four possible contributing pathways'ngestion of cow/goat milk, ingestion of beef, and ingestion of vegetables.
Doses from applicable pathways are calculated for each real 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 is consumed without commercial preparation and vegetable ingestion is included only for those locations where a garden is identiTied.
To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest site 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.
Doses from airborne effluents are presented in Tables 1A and 1B.
DOSES FROM LI UID EFFLUENTS 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 concentrations of radioactivity in the Tennessee River are estimated by a computer model which uses measured hydraulic data downstream of Browns Ferry.
Parameters used to determine the doses are based on guidance given by the NRC (in Regulatory Guides 1.109) for
e
Radiological Impact Assessment Browns Ferry Nuclear Plant January - June 1993 Page 4 of 66 maximum ingestion rates, exposure times, etc. Wherever possible, parameters used in the dose calculation are site specific use factors determined by TVA. The models that are used to estimate doses, as well as the parameters input to the models, are described in detail in the Browns Ferry Nuclear Plant ODCM.
Li uid Release Points and River Dafa Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous.
Allroutine liquid releases from Browns Ferry, 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 willinitiallybe entrained in one-fifthof 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 the first downstream dam, at Tennessee River Mile 283.0.
Doses are calculated for locations between the plant site and the mouth ofthe Tennessee River. The maximum potential recreation dose is calculated for a location immediately downstream from the plant outfall. The maximum 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 (Wheeler Dam). The maximum individual dose from drinking water is assumed to be that calculated at the nearest downstream public water supply (Champion Paper Company).
This could be interpreted as indicating that the maximum individual, as assumed for liquid releases from Browns Ferry, is an individual who obtains all of his drinking water at the Champion Paper Company, 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 below the outfall from Browns Ferry. Dose estimates forthe maximum individual due to liquid effluents for each quarter in the period are presented in Tables 2A and 28, along with the average river flows past the plant site forthe periods.
POPULATION DOSES Population doses for highest exposed organ due to airborne effluents are calculated for an estimated 627,000 persons living within a 50-mile radius of the plant site.
Ingestion population doses are calculated assuming that each individual consumes milk, vegetables, and meat produced with the sector annulus in which he resides.
Doses from external pathways and inhalation are based on the 50-mile human population distribution.
Population doses fortotal body and the maximum exposed organ 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 actual recreational data on the number of shoreline visits at downstream locations.
Population dose estimates for airborne and liquid effluents are presented in Tables 1A, 18, 2A and 28.
DIRECT RADIATION External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployed around BFN. The quarterly gamma radiation levels determined from these TLDs during this reporting period averaged approximately 16.2 mR/quarter at onsite stations and
Radiological Impact Assessment Browns Ferry Nuclear Plant January -June 1993 Page 5 of'6 approximately 14.1 mR/quarter at offsite stations, or approximately 2.1 mR/quarter higher onsite than at offsite stations.
This is consistent with levels reported at TVA's non operating nuclear power plant construction sites where the average radiation levels onsite are generally 2-6 mR/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 ofthe 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.
DOSE TO MEMBERS OF THE PUBLIC INSIDE THE SITE BOUNDARY No routine activities within the site boundary by members of the public have been identified which would lead to their radiation exposure.
TOTALDOSE To determine compliance with 40 CFR 190, annual total dose contributions to the maximum 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 individual is conservatively estimated 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 environmental monitoring program.
This dose is compared to the 40 CFR 190 limitfor total body or any organ dose (other than thyroid) to determine compliance.
The annual thyroid dose to the maximum 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 environmental monitoring program.
This dose is compared to the 40 CFR 190 limitfor thyroid dose to determine compliance.
Cumulative annual total doses are presented in Table 3.

roximations of Total Radioactivit A.
Fission and Activation Gases:
Noble gases in the building vent and stack gaseous effluent 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 flow rate data is consolidated weekly to determine the volume of airborne effluent released from the plant.
The noble gas monitor data is consolidated monthly to determine the total curies of noble gases released during the month.
2 ~
Gas grab samples are. taken and analyzed monthly to determine the relative noble gas activity concentrations.
This information is used to apportion the total curies of noble gases released among different noble gas radionuclides.
3 ~
The tritium concentration is determined by the analysis of a monthly grab sample for each release point.
B. and C. Iodines and Particulates 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.

roximations of Total Radioactivit Continued 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.
D.
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.

ENCLOSURE 3 TENNESSEE VALLEY AUTHORITY SEMIANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT BROWNS FERRY NUCLEAR PLANT (BFN)
INOPERABLE RADIOLOGICAL EFFLUENT INSTRUMENTATION REPORT
This report is to comply with Browns Ferry Nuclear Plant Technical Specifications (TSs), Sections 3.2.D.2, 3.2.K.2 and Offsite Dose Calculation Manual (ODCM),
Sections 1/2.1.1 and 1/2.1.2.
The BFN TS and ODCM require the exertion of best efforts to return inoperable radiological effluent monitoring instrumentation to an operable status within 30 days.
Failure to return the inoperable instruments to an operable status requires a description in the next Semiannual Radioactive Effluent Release Report.
During the reporting period, January 1 through June 30,
- 1993, there was no airborne or liquid radiological effluent instrumentation inoperable for periods The Effluent Monitors, which have been placed in "out-of-service" status with their effluent streams
- isolated, are not applicable for this report.
During this period, Units 1 and 3 were defueled and Unit 2 operating.
