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.

S COND HAL 1

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.

borne Re eases 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 second half of 1988 are listed in Table l.

Li u d Releases

0 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 and equipment drains and sumps.

BFN Rad impact 2nd Half 1988 Page 2 of 50 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'o 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 second half of 1988 are given in Table 2.

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 have alarms which allow for the manual 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 10 CFR 20 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, Less than or equal to 10 mrad-per quarter and 20 mrad per year (per reactor unit) for beta radiation.

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.

body, Less than or equal to 15 mrem per quarter and 30 mrem per year (for the 3-unit site) 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.

OSE CALCULA 0

S 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 vicinity of the plant.

The area around the plant is analyzed -to determine the pathways through which the public may receive a dose.

These pathways are shown in Figure 1.

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.

Many 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.

OSES ROM A BORNE EFFLUENTS BFN Rad Impact 2nd Half'988 Page 4 of 50 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 grounds 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.

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.

rbo e Release Poi ts and Neteoro o

ca Data Meteorological data at Browns Ferry are measured continuously.

Measurements collected include the wind speed, wind direction, and the temperature at heights of 10, 46 and 91 meters above the ground.

Average 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 not distributed by di'rection.

Stability classes are determined from the vertical temperature gradient 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.

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 gradient between 10 and 46 meters.

BFN Rad Impact 2nd Half 1988 Page 5 of 50 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 velocity.

The split-level dispersion approach is implemented using a model that requires two complete average 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 gradient 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 gradient 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.

Stability class D is assumed to persist at the effluent release level of 180 meters for the entire period.

For the period January 1,

1978-December 31, 1980,. stable conditions (E,

F, or G stability) existed in the layer from 46 to 91 meters at Browns Ferry Nuclear Plant (BFN) about 43 percent of the time.

Neutral conditions existed about 56 percent of the time.

This suggests that the use of a D stability for stack releases is conservative or realistic about 99 percent of the time.

The third and fourth quarter JFDs are listed in Tables 3 and 4, respectively.

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 rolli'ng 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.

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.

E osu e Dose - Airbor e 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 based on the reported releases for all nuclides (Table 1) for all receptor points shown on Table 5.

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

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 5.

Doses are calculated based on the reported iodine and particulate releases as shown on Table 1.

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 in the second half of 1988 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.

For a comparison to previous releases and doses, graphs are presented as Figures 2 and 3 which show corresponding airborne releases and doses for the period 1980 to the present.

BFN Rad Impact 2nd Half 1988 Page 10 of 50 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.

i uid R

ease Poi ts and R ver Data Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous.

All routine liquid releases from Browns Ferry at 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 16,460 ft3/s for the third quarter of 1988 and 26,550 ft3/s for the fourth quarter.

ose 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 (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)

BFN Rad Impact 2nd Half 1988 Page 14 of 50 DIRECT RAD ATION 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 17.4 mR/quarter at onsite stations "and approximately 14;7 mR/quarter at offsite stations, or approximately 2.7 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 ac'tivities onsite.

BFN Rad Impact 2nd Half 1988 Page 16 of 50 CONCLUSIO As a result of operation of Browns Ferry Nuclear Plant for the second half of 1988, 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 Limi,ts and Regulatory Guidance.

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.

EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT

SUMMARY

JULY THROUGH DECEMBER 1988 The radioactive effluents for the second half of 1988 were normal for a three unit boiling water reactor plant in its third year of an extended outage.

Because of the extended

outage, only radionuclides with a long half-life (longer than a few months) have not decayed away and are being released to the environment.

The radioactive decay is particularly significant for gaseous effluents because no fission gases or radioactive iodines are being released.

The only radioactive gaseous releases are very small quantities of particulate matter.

The quantity of radionuclides released in liquid effluents during this extended outage is a significant fraction of the quantities released during normal power operation.

The radioactivity being released now in liquid effluents is primarily long half-life radionuclides that have been deposited on the surfaces of piping and components.

During normal outage work this radioactivity is removed by process water that is purified and released to the river.

The water purification process is unable to remove all the radioactivity before it is released to the river.

The release of radioactive material to the environment from Browns Ferry Nuclear Plant has been a small fraction of the 10 CFR 20 Appendix B and 10 CFR 50 Appendix I limits during the second half of 1988.

Perm ss b e Concent at o s A. Fission and Activation Gases in Gaseous Effluent 1.

The instantaneous release rate of fission and activation gases is regulated by the dose rate limit of 10 CFR 20 Appendix B.

The dose rate at'any time to areas at and beyond the site boundary due to noble gases released in gaseous effluents from the site'shall be limited to

< 500 mrem/year to the total body and

< 3000 mrem/year to the skin.

2.

The BFN Offsite Dose Calculation Manual (ODCM) determines the maximum noble gas release rate based upon the dose rate limits in II.A.1.

The instantaneous noble gas release rates are limited by the following equation:

+g2<1 0.15 14.4 Ql = The release rate from the building exhaust vents in Ci/sec.

Q2 = The release rate from the main stack in Ci/sec.

B and C. -Iodines and Particulates with Half Lives Greater than 8 Days in Gaseous Effluents 1.

The instantaneous release rate of'articulates and iodines is regulated by the dose rate limit of 10 CFR 20 Appendix B.

The dose rate at any time to, areas at and beyond the site boundary due to I-131, 'I-133, H-3 and particulates with greater than eight days half-lives released in gaseous effluents from the site shall be limited to '<1500 mrem/yr to any organ.

2.

The BFN ODCM determines the maximum particulate and iodine release rate based upon the dose rate limit of II. B and C.l. The instantaneous iodine and particulate release rates are limited by the following equation:

92

+

g4

<1 2.19 35.7 Q3 = The release rate from the building exhaust vents in pCi/sec Q4 = The release rate from the main stack in pCi/sec.

Qy EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION JULY THROUGH DECEMBER 1988 D. Liquid Effluents 1.

The concentration of radionuclides in liquid effluents released at any time from the site to unrestricted areas shall be limited to the concentrations specified in 10 CFR 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases.

2.

For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 pCi/ml total activity.

III.

Average Energy Not applicable IV.

Measurements and roximations of Tota Radioact vit A. Fission and Activation Gases:

1.

Noble gases in the building vent and stack, gaseous effluent are

'ontinuously 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 cu'ries of noble gases released between 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 0

l.

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

'eekly 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.

q ~~A'I EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL 'INFORMATION JULY THROUGH DECEMBER 1988 IV.

Measurements a d A roximations of Total ad oactivit (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.

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

. month.

0 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.

ENCLOSURE 2

TENNESSE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT INOPERABLE RADIOACTIVE EFFLUENT INSTRUMENTATION REPORT JULY THROUGH DECEMBER 1988

TENNESSEE VALLEY AUTHORITY BROWSES FERRY NUCLEAR PLANT INOPERABLE RADIOACTIVE EFFLUENT INSTRUMENTATION REPORT

Ino erable Radioactive Effluent Instrumentatio Re ort This report is to comply with Radiological Effluent Technical Specifications (RETS) section 3.2.D.2 and 3.2.K.2 reporting requirements for instruments that are inoperable for more than 30 days.

The RETS became effective at BFN on May 6, 1987.

This 'report covers the period from July 1 December 31, 1988.

Because of significant technical specification changes, a large number of radioactive effluent monitoring instruments became technically inoperable on May 6, 1987.

RETS were incorporated during a BFN administrative outage.

Site resources

were, and still are endeavoring to resolve previously identified problem areas.

Modifications required to bring BFN effluent monitoring equipment into technical compliance with RETS complete for resources with other regulatory driven modifications.

This report explains why the inoperability of each instrument was not corrected in a timely manner.

The instruments that were inoperable for more than 30 days are:

RHR service water monitor (1-RM-90-133)

RHR service water monitor (1-RM-90-134)

RHR service water monitor (2-RM-90-133)

RHR service water monitor (2-RM-90-134)

RHR service water monitor (3-RM-90-133)

RHR service water monitor (3-RM-90-134)

Raw cooling water monitor (1-RM-90-132)

Raw cooling water monitor (2-RM-90-132)

Raw cooling water monitor (3-RM-90-132)

Stack effluent flow meter (0-FE-90-271)

Stack effluent monitor (0-RM-90-147A)

Stack effluent monitor (0-RM-90-147B)

During the entire reporting period, fuel was off loaded from all three units and all compensatory sampling requirements were met.

L uid Process Rad ation Monitors BFN RETS Table 3.2.D requires Residual Heat Removal (RHR) service water monitors (1-RM-90-133, 1-RM-90-134, 2-RM-90-133, 2-RM-90-134, 3-RM-90-133, and 3-RM-90-134) and raw cooling water monitors (1-RM-90-132, 2-RM-90-132, and 3-RM-90-132) to be operable when these systems are in service.

Contrary to this requirement, these nine monitors were not available for operability during the entire reporting period.

These monitors were not available for operability because they were not designed to meet the requirements in RETS Table 4.2.D, Footnote 2.

This footnote requires that control room annunciation occur if instrument controls are not set in operate mode.

Design Change Request (DCR) 1687, revision 1, was written to correct this problem and was approved on September 29, 1986.

Engineering Change Notices (ECNs) P0976 (Unit 1), P0977 (Unit 2),

and P0978 (Unit 3) were completed, resolving various design 'problems.

Three RHR service water monitors (1-RM-90-134, 2-RM-90-133, and 2-RM-90-134) and three raw cooling water monitors (1-RM-90-132, 2-RM-90-132 and 3-RM-90-132) were returned to service on December 31, 1988.

2-RM-90-132 was removed from service because the system was not designed to operate at very low RCW discharge flow rates.

Design change notice H 4377 has been written to redesign the suction tap for 2-RM-90-132 to allow obtaining a sample during periods'f abnormally low RCW flow.

Compensatory sampling is being utilized to verify there is no activity in the discharge.

1-RM-90-133, 3-RM-90-133, and 3-RM-90-134 are not in service due to the associated residual heat removal piping being capped and out of service during the entire period.

Stack Radioactive E

uent Instrumentat o

The stack effluent noble gas monitors (0-RM-90-147A and B) and the stack effluent flow meter (0-FE-90-271) were inoperable during this reporting period.

BFN RETS Table 4.2.K, Footnote 1 requires that the stack noble gas monitors be calibrated using National Bureau of Standards (NBS) traceable radioactive standards.

NBS traceable primary calibrations were completed on April 13, 1987.

Operability is dependent upon using this primary calibration information in the performance of periodic surveillance instructions (SIs).

The upgraded SIs incorporating the new calibration results were delayed in being approved due to new procedure format and walkdown requirements.

All applicable surveillance instructions have now been approved.

After completion of ECN 5451, replacement of failed power supply (DCN H1506A), and required SI

testing, the stack effluent monitors (0-RM-90-147A and B) and the stack effluent flow meter (0-FE-90-271) were declared operable on October 1, 1988.

The stack effluent flow meter (0-FE-90-271) was declared inoperable on November 13, 1988 due to a failed temperature transmitter.

After receiving the necessary spare parts, the stack effluent flow meter was repaired and returned to service on December 22, 1988.

Fuel was off-loaded for all three units during this period.

Results of compensatory lab analyses of stack effluent indicated no anomolies.
