(BFN) Offsite Dose Calculation Hanual (ODCH) is attached.

A summary of the major changes (those involving the dose calculational methodology) is as fo1 1 ows:

1.

Heteorological data period of record revised from 1974-75 to 1977-79.

2.

Split-level JFD not considered for release rate limits.

3.

Wind speed midpoint for > 10.9 m/s revised.

4.

Instantaneous release rate limits revised due to new meteorological data and new finite cloud approximation.

5.

Finite cloud approximation revised for stack releases.

6.

Critical receptor locations revised to agree with latest land-use census data.

7.

Nuclides analyzed on a monthly basis were expanded for noble gases and iodines and particulates.

8.

Heteorology for dose projections has been included.

Anal sis or Evaluation Justif in 'the Chan e

These changes are made to reflect changes in methodology which have been implemented at other TVA plants in the time since the BFN ODCH was originally submitted to NRC in 1983.

These changes are an attempt to make the BFN ODCH consistent with other plants and with the current models being used for dose assessment in TVA.

the Set pints or Dose Calculations These changes will cause the setpoint calculations and dose calculations to be more reliable and more accurate due to the improvements in the model.

Desc i tion of chan~ c Section 2,0 (Liquid Ef fluents) was rewritten to clarify the descriptions of the calculations being performed.

The majority of the changes were not changes in methodology; rather, they involved the movement of paragraphs, the addition and/or deletion of text to make the description clearer to the reader, and the changing of subscript identifiers in order to use the same subscripts for the same quantity throughout the section.

These minor editorial changes require no analysi or justification and will not change the setpoints or dose calculations.

The major changes involving the dose calculational methodology being used are outlined below:

Section 2.3.3 Honthly Analysis 1.

The l:st of isotopes considered was expanded to include 18 single isotopes and two parent/daughter pairs in the calculation.

2.

'The list of or'gans considered in the calculation was expanded.

Organs considered are the bone, gastrointestinal tract, thyroid, liver, and total body.

3.

The child age group was added to the adult age group for consideration.

4.

The volume of water used:for dilution in the calculation was changed from the.dilution flow during releases to the average riverflow past the site for the month.

5.

A recreational dose is calculated for the monthly analysis which considers 4 isotopes (Co-58, Co-60, Cs-134 and Cs-137) which are expected to contribute over 95'/. of the total recreational dose.

The total body dose due to shoreline exposure is calculated for these 4 nuclides and added to both the total body and.the maximum organ doses.

6.

The administrative (guideline) release limits, given in curies, were deleted.

7.

Several sentences were added to section 2.3.2.4 to outline how the final monthly doses are obtained, i.e.,

how the individual pathway. doses are summed to find the total body "nd maximum organ doses to be compared to the Technical Specif ications.

Descript on of chan.es (continued)

Section 2.3.3 Quarterly and Annual Analysis 5.

6.

7.

The recreation pathway was added to the quarterly and annual analysis section.

The skin was added as an organ to be considered in the analysis.

3.

The child age group was added to the calculation.

4 ~

The consumption rates were made consi tent by taking all values from Regulatory Guide 1.109.

A calculation of population doses was added.

The section containin activity 'mits for releases was dele ed.

Table 2.1 was replaced with an updated table reflecting the addition of nuclides to the ones already in use, and the addition of the child as an age group to be considered.

8.

Tables 2.2, 2.3, and 2.4 were added to include information which is used in the calculation of doses.

1.1 Alarm/Tri Set pints Technical Specification 3.8.8.1 requires that the dose rate in unrestricted areas (Figure 1.1) due to gaseous effluents from the BFH site shall be limited at all times to the following values:

1.

500 mrem/yr to the total body and 3,000 mrem/yr to the skin from noble gases.

2.

1,500 mrem/yr to any organ from radioiodines and particulates.

Technical Specification 3.2.K.l requires gaseous effluent monitors to have alarm/trip setpoints to ensure that the above dose rates. are not exceeded.

This section of the ODCN describes the methodology that will be used to determine these setpoints.

The methodology for determining alarm/trip setpoints is divided into two major parts.

The first consists of backcalculating from a dose rate to a release rate limit relation for each nuclide type and release point.

The second consists of using the release rate limit relations to determine the physical settings on the monitors.

The methodology for the latter is contained in Technical Instruction 15.

1.1.1 ReIease Rate Limit Methodolo Ci/s Ste 1

Dose Rates The first step involves calculating a dose rate based on the design objective source term mix used in the licensing of the plant.

Historical meteorological data are used in this calculation.

Doses are determined for (1) noble gases and (2) iodines and particulates.

Depending on the pathway involved, either air concentrations or ground concentrations are calculated.

Figures 1.2 and 1.3 show the Offgas System, the Standby Gas Treatment System and normal building ventilation with effluent monitor 'locations.

A.

Hoble Gases Equations and assumptions for calculating doses from noble gases are as follows:

Assumotions:

l.

Doses to be calculated are total body and skin.

2.

Exposure pathway is submersion within a cloud of noble gases.

3.

Noble gas radionuclide mix is based on the expected source term given in Table 1.1.

4.

Basic radionuclide data are given in Table 1.2.

5.

6.

All releases are'treated as ground level or elevated.

Meteorological data are expressed as joint-frequency distributions of wind speed and wind direction by atmospheric stability for the period January 1977 to December 1979 (Table 1.3).

Releases fron the radwaste, reactor and turbine buildings are treated as 100 percent ground level, whereas stack releases are considered 100 percent elevated.

7.

Raw meteorological data for ground level wind speed and direct',on measurements at measurements at 10m and 45m.

Nindspeeds elevated releases were measured at 93m.

was assumed to persist during the entire releases.

releases consist of 10m and temperature and directions for Stability Class D

period for elevated 8.

Dose is to be evaluated at the nearest land site boundary point in each sector and at other locations expected to be maximum exposure points (Table 1.4).

9.

A semi-infinite cloud model is used.

The use of a finite cloud model would result in calculated doses of 0 to 10 percent higher than those calculations using the semi-infinite cloud model for BFH.

10.

Ho credit is taken for shielding by residence.

ll. Plume depletion (Figure 1.4) and radioactive decay are considered consistent with Regulatory Guide 1.111 methodology.

12. Building wake effects on effluent dispersion are considered.

13.

A sector-average dispersion equation is used consistent with Regulatory Guide 1.111.

14.

The wind speed classes that are used are as 'follows:

17. Environmental transfer data are consistent with NUREG/CR-1 004.

~Euati one To calculate the dose from radiological effluents discharged from a given release point for any one of the 16 potential maximum-exposure points, the following equations are used.

he

For effluents exhausted from release points that are higher than twice the.--

height of adjacent structures (elevated releases) the effective release height is determined by the following equation, consistent with Regulatory Guide 1.111 where he

= hs + hpr

m physical height of release

point, m.

I'aximum terrain height between release'-point and receptor location, m.

For effluents released from points less than. the height of adjacent structures, a ground level release is assumed (he 0).

For effluents released from points at the level of or above adjacent structures, but lower than elevated release

points, releases are

.treated as follows:

Case 1

elevated if Wo/u > 5.

Case 2 ground level (he

= 0) if Hp/0 < l.

Case 3 split level if 1

< wo/U < 5.

Under Case 3 a split level dispersion approach is implemented

using, a model that requires for each release point two 3FDs, one for elevated releases and one for ground level releases.

The summation of the elevated and ground level JFDs account for the total period of record.

Releases are considered to be elevated 100(l-Et) percent of the time and ground level 100 Et percent of the time where the entrainment coefficient, Et, is defined by Et = 2.58 1.58(Wo/u) for 1

The above dose calculations are repeated for each release point (vent or stack) and then summed to obtain maximum total body and skin dose rates.

The maximum total body and skin dose rates will then=be used in step 2.

B.

Iodines and Particulates Equations and assumptions for calculating doses from radiosodines and particulates are as follows; 1.

Dose is to be calculated for the critical organ, thyroid, and the critical age group, infant.

2.

Exposure pathways from iodines and particulates are milk ingestion, ground contamination, and inhalation.

3.

The radioiodine and particulate mix is based on the expected source term given in Table 1.1.

4.

where 23

+ QA<l r3 r4 instantaneous release rate from build1ng exhaust vents in yCi/s.

To simplify the dynamic operation of the plant, the dose rate limits were transformed into conservative release rate limits based on histot ica~ource terms and meteorology.

The values, listed below were used as administrative guidelines for'operation and development of alarm/trip setpoints (see Technical Instruction 15) to ensure that the instantaneous dose rate limits are not exceeded.

Airborne Elevated Ground Level Noble Gas 14.4 Ci/s 0.15 Ci/s Iodine and Particulate 35.7 yCi/s 2.19 pCi/s 1.2 Monthl Dose Calculations Dose calculations will be performed monthly to determine compliance with specifications 3.8.8.3 and 3.8.8.5.

The specifications require that the dose rate in unrestricted areas due to gaseous effluents from each reactor at the, site shall be'imited to the following values:

For noble gases, l.

During any calendar quarter, 5 mrad to air for gamma radiation and 10 mrad to air for beta radiation.

2.

During any calendar year, 10 mrad to air for gamma radiation and 20 mrad to air for beta radiation.

t For iodines and particulates, 1.

During any calendar quarter, 7.5 mrem to any organ.

2.

During any calendar year, 15 mrem to any organ.

This section of the ODCM describes the methodology that will be used to perform these monthly calculations.

Doses will first be calculated by a simplified conservative approach (step 1).

If these exceed these limits, a more realistic calculation will be performed (step 2).

II t 1.3 uarterl and Annual Dose Calculations 7 A complete dose analysis utilizing the total estimated" gaseous releases for each calendar quarter will be performed and reported as required in the Technical Specification 6.7.5. Methodology for this analysis is the same as that described.in Section 1.1.1, except that real pathways and receptor locations (Table 1.4) are considered and releases from the radwaste and reactor buildings are treated as split level. Also, raw meteorological data for ground level releases consist of windspeed and direction measurements at 10m and temperature measurements of 10m and 45 m. The ground level portion of the split level 3FD consist of wind speeds and directions measured at the 10m level and temperature measurements at 10m and 45m. The elevated portion of the split level JFD is based on wind speeds and directions measured at the 46m level and. temperature measurements at 45m and 90m. Windspeeds and directions for elevated releases are measured at 93m. Stability class D is assumed to persist during the entire period for elevated releases. In addition, meteorological data representative of each corresponding calendar quarter will be used. This analysis will replace the estimates in Section 1.2. At the end of the year an annual dose analysis will be performed by calculating the sum of the quarterly doses to the critical receptors.

1.4 Gaseous Radwaste Treatment S stem 0 e'ration The gaseous radwaste treatment system (GRTS) described below'hall be maintained and operated to keep releases ALARA. 1.4.1 S stem Desci i tion A flow diagram for the GRTS is given in Figure 1.3. The system includes the subsystems that process and dispose of the gases from the main condenser air ejectors, the startup vacuum pumps,.and the gland seal condensers. One gaseous radwaste treatment system is provided for each unit. The processed gases from each unit are routed to the plant st'ack for dilution and elevated release to the atmosphere. The air-ejector off-gas line of each unit and the stack are continuously monitored by radiation monitors. 1.4.2 Dose Pro'ections Doses will be projected monthly in accordance with the procedures in. the plant's Radiological Effluent Manual (REM). This will be done by averaging the calculated dose for the most recent month and the calculated dose for the previous month and assigning that average dose as the projection for the current month. These doses will be used to monitor radwaste system performance. 2.0 Li uid Effluents 2.1 Release Rate Limit Methodolo 2.1.1 RETS Re uirement Specification 3.8.A.l of-the Radiological Effluent Technical Specifications (RETS) requires that the concentration of radioactive material released at any time from the site to unrestricted areas (Figure 2.1) shall be limited to the Maximum Permissible Concentration (MPC) specified in 10 CFR 20, Appendix 8, Table II, Column 2 for nuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2xl0 'Ci/ml total activity. To ensure compliance, the following approach will be used for each release. 2.1.2 Prerelease Anal sis Prior to release, a grab sample will be analyzed to determine the concentration (C;) of each gamma emitting radionuclide i in the radwaste tank. The following equation is used to calculate MPC fractions (Mi). where: C MPCi (2.1) MPC fraction of radionuclide i. Ci = concentration of radionuclide i in the radwaste

tank, yCi/mK.

MPCi = MPC of radionuclide i as specified in Section 2.1.1, yCi/mi. t The sum of the ratios (R) will be calculated by the following relationship: (2.2) where: ~ M = the sum of the ratios. = HPC fraction from equation 2.1. 2.1.3 Release Flow Rate Calculations There is one liquid release point into the discharge canal by one of-three possible modes: open 3 pumps 9 200,000 gpm/pump helper 3 pumps 8 180,000 gpm/pump closed 50,000 gpm Oischarge conduit 1 The sum of the ratios at the diffuser pipes must be < 1 due to the 'eleases from the above source. The following relationship will assure this criterion is met: f (R 1) F (2.3) where: = the effluent flow rate (gallons/minute) before dilution. R = the sum of the ratios as determined by Equation 2.2. F = minimum dilution flow rate for prerelease analysis. The allowable release rate is calculated before each release and the release rate is continuously monitored during the release so that the HPC limit is not exceeded. 2.2 Instrument Set pints 2.2.1 Set oint Determination The setpoint for each liquid effluent monitor will be established using plant instructions. Concentration, flow rate, dilution, principal gamma emitter,

geometry, and detector efficiency are combined to give an equivalent setpoint in counts per minute (cpm).

The locations and identification numbers for each liquid effluent radiation detector are shown in figures 2.2 and 2.3. The respective alarm/trip setpoints will be set such that Equation 2.3 is satisf'ied. The methodology describing the setpoint determination is contained in Technical Instruction 45. 2.2.2 Post-Release Anal sis A post-release analysis will be done using actual release data to ensure that the limits specified in Section 2.1.1 were not exceeded. A composite list of concentrations (Ci) by isotope, will be used with actual liquid radwaste (f) and dilution (F) flow rates (or volumes) during the release. The data will be substituted into Equations 2.1, 2.2 and 2.3 to demonstrate compliance with the limits in Section 2.1.1. This data and setpoints wi 11 be recorded in t auditable records by plant personnel. 2.3 Dose 2.3.1 RETS Re uirements Specification 3.8.A.3 of the Radiological Effluent Technical Specifications (RETS) requires that dose or dose commitment to an individual from radioactive material in liquid effluents released to unrestricted areas (Figure 2.1) from each reactor shall be limited: 'a ~ During any calender quarter to < 1.5 mrem to the total body and to < 5 mrem to any organ, and b. During any calendar year to < 3 mrem to the total body and to < 10 mrem to any organ. To ensure compliance,'umulative dose calculations wilp be performed at least once per month according to the following methodology. 2.3.2 Monthl Anal sis Principal radionuclides wi 11 be used to conservatively estimate the monthly contribution to the cumulative dose. If the projected dose calculated by this monthly method exceeds the monthly fraction of the annual limits in section 2.3.1, then the methodology in Section 2.3.3 will be implemented. The 20 nuclides (listed below), based on operational source terms, contribute more than 95 percent of the total estimated dose to the total body and the most critical organ for both the water and fish .ingestion pathways. The organs considered for both water ingestion and fish ingestion are the gastrointestinal tract (GIT), bone, thyroid, and liver. 8-3 Ha-24 Cr-51 Mn-54 Fe-55 Fe-59 Co-58 Co-60 Zn-65 Sr-89 Sr-90 '2r/Hb-95 Mo/Tc-99m Ag-110m Sb-124 2-1 31 . I-133 Cs-134 Cs-136 Cs-137 A conservative calculation of the monthly dose will be done according to the following procedure. First, the monthly operating report containing the release data will be obtained and the 'ctivities reported (if any) for each of the above 20 radionuclides ~ ~ ~ ~ ~ will be noted. This information will'then be used in the following calculations. 2.3.2.1 Mater In estion ~ ~ ~ ~ ~ ~ ~ The dose to an individual from ingestion of water is described by the following equation. 20 Djk ~l0~ 7 (DCF)ijk Iikmrem i~1 where: (2 4) dose for the jth organ and the kth age group from the 20 radionuclides, mrem. the organ of interest (bone.

In this case the activity ingested of the ith radionuclide due to eating fish (Iik) is described by Ai Bi~H Fd (7.34 x 10' where: (2.7) Ai 1 = activity released of the ith radionuclide during the

Inserting this for Iik in equation 2.4, the dose equation for fish ingestion then becomes:

t 2.3.2.3 Recreation For the recreation dose calculation, the total dose is".estimated based on a calculation of the shoreline dose for Co-58, Co-60, Cs-134, and Cs-137. The shoreline dose due to these four nuclides is expected to contribute over 95 percent of the total recreation dose. The total body and maximum organ dose to an individual via-the shoreline recreation pathway are assumed to be equal. The recreation dose is described by the following equation: 1 g ~ROCF i~i~67 4 0.95 8760 {2.9) where: r D= recreation dose from plant releases, mrem. 0.95 = conservative correction factor for considering only 4 radionuclides.

This value wi 11 be compared to the Technical Specification limit for total body dose. To obtain the total monthly dose to the maximum organ, sum the maximum organ dose from water ingestion, the maximum organ dose from fish ingestion, and the recreation dose. This value will be compared to the Technical Specification limit for maximum organ dose. .Calendar quarter doses are first estimated by suoming the doses calculated for each month in that quarter. Calendar year doses are first estimated by summing the doses calculated for each month in that year. However, if the annual doses determined in this manner exceed or approach the specification limits, doses calculated for previous quarters with the methodology of Section 2.3.2 will be used instead of those qGarterly doses estimated by summing monthly results. An annual check will be made to ensure that the monthly dose estimates account for at least 95 percent of the dose calculated by the method -. ~ described in Section 2.3.3. If less than 95 percent of the dose has'een estimated, either a new list if principal isotopes will be prepared or a new correction factor wi 11 be used. The latter option will not be used if less than 90 percent of the total dose is predicted. 2.3.3 uarterl and Annual Anal sis' complete analysis utilizing the total estimated liquid releases for each calendar quarter will be performed and reported as required in Section 6.9 of the Technical Specifications. This analysis will replace previous estimates calculated using Section 2.3.2 methodology and will also include an approximation of population 'oses. 2.3.3.1 Individual Doses .The dose, Djk, to the maximum individual from n nuclides is described by: 5 n Djk g Dijkm, rem m=1 i=1 (2.12) n 2 5 f(DCF)ijk ~ Iikm~ + g [(ROCF) ijm Vim ~ Tm v], rem (2.13) i 1 m=1 m=3 where: Dljkm dose to the jth organ for the kth age group from the ith radionuclide via the mth exposure path the organ of interest (bone, GI tract, thyroid, liver, total body and skin). = the age group being considered: adult or child for the ingestion pathways; adult for the recreation pathways. exposure pathway of interest:

Doses will be projected monthly to assure compliance. 2.5 Dose Pro ections In accordance with the REM, dose projections wi 11 be performed. This will be done by averaging the calculated dose for the most recent month and the calculated dose for the previous month and assigning that average dose as the projection for the current month.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ 3.1 Monitorin Pro ram An environmental radiological monitoring program as described in Tables 3.1 and 3.2 and in Figures 3.1, 3.2, 3.3, and 3.4 shall be conducted. Results of this program shall be reported in accordance with Section F-1 of the REM. The atmospheric environmental radiological monitoring program shall consist of 10 monitoring stations from which samples of air particulates and radioiodine shall be collected. The terrestrial monitoring program shall consist of the collection of vegetation, milk, soil, drinking water, and food crops. In addition, direct galena radiation levels will be measured at 40 or more locations in the'icinity of the plant. The reservoir sampling program shall consist of the, collection of samples of surface water,

sediment, and.fish.

Oeviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, sample 'navilability, or malfunction of sampling equipment. If the latter, every effort shall be made to complete corrective action prior to the end of the next sampling period. t 3.2 Oetection Ca abilities Analytical techniques shall be such that the detection capabilities listed in Table 3.3 are achieved. 3.3 Nonroutine Reool ts Honroutine reports shall be submitted pursuant to Section F-3 of the REM. 4.0 Annual Maximum Individual Ooses Total To determine compliance with 40 CFR 190, the annual dose contributions ~ ~ ~ ~ ~ ~ to the maximum individual from SFH radioactive effluents and all other nearby uranium fuel cycle sources will be considered.-, The annual dose to the maximum individual will be conservatively estimated by: first, sumning the total body air submersion

dose, and the critical organ dose from gaseous effluents;,the total body dose, and critical organ dose from liquid effluents for each quarter. in accordance with sections.1.3 and 2.3.3 Then to this sum for each quarter'is added any identifiable increase in direct radiation dose levels attributable to the plant as determined by the environmental monitoring program outlined in section 3.0.

These quarterly sums are then conservatively summed for the four calendar quarters to estimate the maximum individual dose for the year.
