BFN Rad Impact July-Dec 1990 Page 1 of 53 Radiological Impact Assessment Browns Ferry Nuclear Plant July December 1990 INTRODUCTION Potential doses to maximum individuals and the population around Browns Ferry are calculated for each quarter as required in Section F.2 of the Radiological Effluent Manual.

Measured plant releases for the reporting period are used to estimate these doses.

Dispersion of radioactive effluents in the environment is estimated in accordance with the guidance provided by Regulatory Guides 1.109, 1.111 and 1.113 using meteorological data and riverflow data measured during the period.

Using dose calculation methodologies which are described in detail in the Browns Ferry Offsite Dose Calculation Manual, the doses are calculated and used to determine compliance with the dose limits contained in Browns Ferry's Operating License.

In this report, the doses resulting from releases are described and compared to quarterly and annual limits established for Browns Ferry.

SUMMARY

OF LI UID AND GASEOUS EFFLUENT RELEASES SECOND HALF 1990 Although nuclear plants are designed to contain the radioactive material created by the fission process, small amounts of this material escape from the fuel rods.

Also, very small amounts of the structures and components of the systems become activated through the bombardment of neutrons and are worn away.

This radioactive material can be transported throughout plant systems and released to the environment.

Airborne Releases The noble gas fission products do not mix with water and are given off in a gaseous form.

A very small amount of solid radioactivity is given off along with these noble gases.

The most significant, releases are processed so that the radioactive material is filtered and/or decayed prior to release through the plant vents.

Sampling and monitoring methods are used to determine the amount of radioactive material released.

If these methods indicate that radioactivity in airborne effluents is above preset limits, then releases are terminated.

Airborne releases for each quarter in the period are given in Section 1 of this submittal.

Li uid Releases Some small amounts of radioactive material migrate into the primary coolant water.

The primary coolant water is routed through a

purification system to remove most of these particles; however, not all are removed.

Some of the radioactive liquids may leak from pipes or valves in the system.

These liquids are collected in floor 9103050324 910228 PDR ADOCK 05000259 R

PDR

BFN Rad Impact July-Dec 1990 Page 2 of 53 and equipment drains and sumps.

The collected liquids are then processed through a clean-up

system, composed of storage

tanks, recycling systems, and demineralizers, to remove contaminants.

The purified water is then monitored to determine the amount of radioactive material remaining, in the water prior to its release.

Steps are taken to ensure that the amount of radioactivity released to the environment. is as low as reasonably achievable (ALARA). If the levels of radioactivity are above preset limits, the releases are circulated through the clean-up system again for additional processing.

All radioactivity released from the plant into the Tennessee River is quantified prior to release.

Liquid releases for each quarter in the period are given in enclosure 1 of this submittal.

Effluent Monitorin Plant paths through which radioactivity is released are monitored.

These monitors record the radiation levels for each release.

Monitors which are used for liquid releases will automatically alarm and stop any release which is above regulatory limits.

Gaseous release monitors also provide alarming mechanisms to allow for the termination of any release above limits.

DOSE LIMITS The U.S. Nuclear Regulator Commission (NRC) requires nuclear power plants to be designed, built, and operated in such a way that the levels of radioactive material released into unrestricted areas is as low as reasonably achievable (ALARA).

To ensure that this is

done, the plant's operating license includes Technical Specifications which govern the release of radioactivity.

These Technical Specifications specify limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of these effluents.

These limits are set.

well below the NRC 10CFR20 limits which govern the concentrations of radioactivity and exposures permissible in unrestricted

areas, This ensures that radioactive effluent releases are ALARA.

The Technical Specification 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.

BFN Rad Impact July-Dec 1990 Page 3 of 53 t

The Technical Specification limit for the dose to a member of the general public at or beyond the site boundary from iodines and particulates released in airborne effluents is:

Less than or equal to 7.5 mrem per quarter and 15 mrem per year (per reactor unit) to any organ.

The Technical Specification 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 for total dose to the public in the vicinity of 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.

DOSE CALCULATIOHS 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 HRC (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.'any of these factors are obtained from NUREG/CR-1004.

The values chosen will tend to overestimate the dose to this "maximum" person.

The expected dose to actual individuals is lower.

The calculation methods and results of the calculations are presented in the following sections.

I l

BFN Rad Impact July-Dec 1990 Page 4 of 53 t

DOSES FROM AIRBORNE EFFLUENTS For airborne effluents, the public can be exposed to radiation from several sources:

direct radiation from the radi.oactivity 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 radioactivt.ty deposited from the atmosphere onto vegetation which is then eaten by milk and beef animals.

The concentrations of radioactivity in the air and the soil are estimated by the computer model GELC which uses the actual meteorological conditions to determine the distribution of the effluents in the atmosphere.

Again, as many of the parameters as possible are based on actual site specific data.

The model that is used to estimate

dose, as well as the parameters input. to the model, is described in detail in Section 1.0 of the Browns Ferry Nuclear Plant Offsite Dose Calculation Manual.

Airborne Release Points and 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.

A joint frequency distribution gives the percentage of the time in a quarter 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 0.7 m/s (1.5 mph).

Stability classes are determined from the vertical temperature difference between two measurement levels.

There are four routine release points from Browns Ferry Nuclear Plant: the turbine building, the radwaste building, the reactor building, and the stack.

BFN Rad Impact July-Dec 1990 Page 5 of 53 Releases from the turbine building are considered ground-level releases to determine the dispersion of the airborne effluents.

The ground-level JFD is derived from windspeeds and directions measured 10 meters above ground and from the vertical temperature difference between 10 and 46 meters.

Releases from the radwaste and reactor buildings are considered split-level releases to determine the dispersion of the airborne effluents.

This means that 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 di.fference 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 verti.cal temperature difference between 46 and 91 meters.

Releases from the stack are considered elevated-level releases to determine the dispersion of the airborne effluents.

The JFDs for elevated releases are based on wind directions and wind speeds measured at 91 meters and the vertical temperature difference t

between 46 and 91 meters.

The enerall o en terra' y

p xn 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/Mheeler 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.

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.

osure Dose Airborne Effluents Dose estimates for maximum external air exposures (gamma-air and beta-air doses) are made for points at and beyond the site boundary.

These doses are calculated for all receptor points shown on Table 3.

The reported dose is chosen for the offsite location with the highest calculated exposure during the quarter.

These doses are calculated based on the reported releases for noble gases for all receptor points shown on Table 3.

The highest of these exposures is chosen and is assumed to be the maximum individual dose.

BFN Rad Impact July-Dec 1990 Page 8 of 53 Or an Dose Airborne Effluents Internal 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:

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

Doses from applicable pathways are calculated for each real receptor location defined in Table 3.

Doses are calculated based on the reported iodine and particulate releases.

To determine the maximum organ dose, the dose contribution from the three 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.,

'ilk 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 identified.

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.

The organ doses calculated for Browns Ferry Nuclear Plant for each quarter are shown below.

Xf this limit is exceeded, the release data is reanalyzed to determine which portion of the releases were attributable to each reactor unit.

Then these per unit releases can be used to calculate pex unit doses which are compared to the pex unit dose limits.

As is shown by the table, all calculated quarterly doses were well below the allowable limits established in Browns Ferry's Technical Specifications.

For a comparison to previous releases and doses, graphs are presented as Figures 1 and 2 which show corresponding airborne releases and doses for the period 1980 to the pxesent.

BFN Rad Impact July-Dec 1990 Page 10 of 53 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 in the river 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 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 the Browns Ferry Nuclear Plant Offsite Dose Calculation Manual.

Li uid Release Points and River Data Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous.

All routine 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 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, at Tennessee River Mile 283.0.

The average river flows past the plant site were 32,031 ft /s for the third quarter of 1990 and 52,980 ft~/s for the fourth quarter.

Dose Estimates Li uid Effluents Doses are calculated for recreation, consumption of fish, and drinking water for locations between the plant site and the mouth of the 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

BFN Rad Impact July-Dec 1990 Page 11 of 53 (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 21 kg (6.9 kg for a child) per year of fish caught from the Tennessee River between BFN and Wheeler

'Jo 1 fo The quarterly limit for liquid doses is the total site dose limit (the one-unit dose limit times 3).

This is because all liquid radwaste systems are common to all 3 units and the releases cannot be attributed to one particular reactor unit.

As is shown by the table, all calculated quarterly doses were well below the allowable limits established in Browns Ferry's Technical Specifications.

For a comparison to previous releases and doses, graphs are presented as Figure 3 which shows corresponding liquid releases and doses for the period 1980 to the present.

BFN Rad Xmpact July-Dec 1990 Page 13 of 53 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 for total body and the maximum exposed organ due to liquid effluents are calculated for the entire downstream Tennessee River Population.

Mater 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 below.

Population doses can be compared to the natural background dose for the entire 50-mile population of about, 56,430 man-rem/yr (based on 90 mrem/year for natural background).

BFN Rad Impact July-Dec 1990 Page 14 of 53 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 17.6 mR/quarter at onsite stations and approximately 15.2 mR/quarter at offsite stations, or approximately 2.4 mR/quarter higher onsite than at offsite stations.

This is consistent with levels reported at TVA's nonoperating 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 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.

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.

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 limit for total body or any organ t

dose (other than thyroid) to determine compliance.

REVISED PAGES FOR FIRST HALF 1989 RADIOLOGICAL IMPACT TO MAN REPORT
BFN Rad Impact 1st Half 1989 Page 8 of 53 Or an Dose Airborne Effluents nternal doses to organs due to releases of airborne effluents are stimated for the inhalation, ground contamination, and ingestion pathways.
The ingestion pathway is further divided into four possible contributing pathways:
ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables.
Doses from applicable pathways are calculated for each real receptor location defined in Table 3.
Doses are calculated based on the reported iodine and particulate releases.
To determine the maximum organ dose, the dose contribution from the three 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 identified.
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.
The organ doses calculated for Browns Ferry Nuclear Plant for each quarter are shown below.

Since airborne releases are quantified on a per site basis, and the Technical Specification dose limits are given on a per unit basis, calculated airborne doses are initially compared to the per unit limit.
If this limit is exceeded, the release data is reanalyzed to determine which portion of the releases were attributable to each reactor unit.
Then these per unit releases can be used to calculate per unit doses which are compared to the per unit dose limits.
As is shown by the table, all calculated quarterly doses were well below the allowable limits established in Browns Ferry's Technical Specifications.
For a comparison to previous releases and doses, graphs are presented as Figures 1 and 2 which show corresponding airborne releases and doses for the period 1980 to the present.

BFN Rad Impact 1st Half 1989 Page 13 of 53 POPULATION DOSES opulation doses for highest exposed organ due to airborne effluents re 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 for total 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 below.

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 limit for thyroid dose to determine compliance.

BFN Rad Impact 1st Half 1989 Page 16 of 53 CONCLUSIO s a result of operation of Browns Ferry Nuclear Plant for the econd half of 1989, radioactive effluents were released to the atmosphere and the Tennessee River.
The released radioactivity resulted in estimated potential doses to. the public which are well below the Technical Specification Limits and Regulatory Guidance.
Cumulative doses for the calendar year are given below along with a comparison to the respective annual limits for the doses.

Since airborne releases are quantified on a per site basis, and the Technical Specification dose limits are given on a per unit basis, calculated airborne doses are initially compared to the per unit limit.
If this limit is exceeded, the release data is reanalyzed to determine which portion of the releases were attributable to each reactor unit.
Then these per unit releases can be used to calculate per unit doses which are compared to the per unit dose limits.
The quarterly Technical Specification limit for liquid doses is the total site dose limit (the one-unit dose limit times 3).
This is because all liquid radwaste systems are common to all 3 units and the releases cannot be attributed to one particular reactor unit.
