TURKEY POINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFFLUENT RELEASE REPORT JANUARY 1993 THROUGH DECEMBER 1993 Aliquots of representative pre-release samples, from waste disposal system, were isotopically analyzed for gamma emitting isotopes on a multichannel analyzer.

Frequent periodic sampling and analysis were used to conservatively determine if any radioactivity was being released via the steam generator blowdown system and the storm drain system.

Monthly and quarterly composite samples for the waste disposal system were prepared to give proportional weight to each liquid release made during the designated period of accumulation. The monthly composite was analyzed for tritium and gross alpha radioactivity. Tritium was determined by use of liquid scintillation techniques and gross alpha radioactivity was determined by use of a solid state scintillation system.

The quarterly composite was analyzed for Sr-89, Sr-90 and Fe-55 by chemical separation.

All radioactivity concentrations determined from analysis of a pre-release composite were multiplied by the total represented volume of the liquid waste released to determine the total quantity of each isotope and of gross alpha activity released during the compositing period.

Aliquots of representative pre-release samples from the waste disposal system were analyzed on a per-release basis of gamma spectrum analysis. The resulting isotope concentrations were multiplied by the total volume released in order to estimate the total dissolved gases released.

The liquid waste treatment system is shared by both units at the site and generally all liquid releases are allocated on a 50%-50% basis to each unit respectively.

There were no continuous liquid effluent releases above the lower limit of detection for either Unit 3 or Unit 4 during this reporting period and therefore have been omitted from Table 2 of this report.

~ 4.2 a u Bfflu nt Airborne releases to the atmosphere occurred from: release of Gas Decay Tanks, the Containment Instrument Bleed Line, Containment Purges, and releases incidental to operation of the plant. The techniques employed in determining the radioactivity in airborne releases are:

a) Gamma spectrum analysis for fission and activation gases, b) Removal of particulate material by filtration and subsequent gamma spectrum analysis, Sr-89, Sr-90 determination and gross alpha.

c) Absorption of halogen radionuclides on a charcoal filter and subsequent gamma spectrum analysis, and d) Analysis of water vapor in a gas sample for tritium using liquid scintillation techniques.

All gas releases from the plant which were not accounted for by the above methods were conservatively estimated as curies of Xe-133 by use of the SPING-4 radiation monitor and the Plant Vent process monitor recorder chart and the current calibration curve for the monitor.

Portions of the gas waste treatment system are shared by both units and generally all gas releases from the shared system are allocated on a 50/50 basis to each unit.

Meteorological data for the period January 1993 through December 1993, in the form of Joint Frequency Distribution Tables, is maintained on-site.

TURKEY POINT UNITS 3 AND 4 ANNUALRADIOACriVEEFFLUENf RELEASE REPORT JANUARY 1993 THROUGH DECEMBER 1993 a) Sampling Error The error associated with volume measurement devices, flow measuring devices, etc., based on calibration data and design tolerances has been conservatively estimated to be collectively less than+10%.

b) Analytical Error Our quarterly Q.C. cross-check program involves counting unknown samples provided by an independent external lab. The errors associated with our analysis of these unknown samples, and reported to us by the independent lab, were used as the basis for deriving the following analytical error terms. The tritium results reported in Tables 1 and 3 for Units 3 and 4 of this report were increased by a factor of 1.32 due to a suspected error in the tritium analysis. A revision to this report will be issued to the NRC within thirty days of completion of the investigation.

Note 2: Dry compressible waste volume indicates volume shipped to burial site following reduction by a waste processing facility. Volume qhipped to the waste processing facility was 1232. 4 m Note 3: Material transported to Oak Ridge, Tennessee, was consigned to licensed processing facilities for volume reduction and decontamination activities. The material remaining after processing was transported by the processor to Barnwell, South Carolina, for burial.

The total curie quantity and radionuclide composition of solid waste shipped from the Turkey Point Plant Units 3 and 4 are determined using a combination of qualitative and quantitive techniques. The Turkey Point Plant follows the guidelines in the Low Level Waste Licensing Branch Technical Position on Radioactive Waste Classification (5/ll/83) for these determinations.

The most frequently used techniques for determining the total activity in a package are the dose to curie method and inference from specific activity and mass or activity concentration and volume. Activation analysis may be applied when it is appropriate. The total activity determination by any of these methods is considered to be an estimate.

25

TURKEY POINT UNITS 3 AND 4 ANNUAL RADIOACTIVE EFFLUENTS RELEASE REPORT TABLE 6 The composition of radionuclides in the waste is det:ermined by both on-site analysis for principle gamma emitters and periodic off-site analyses for difficult to measure isotopes. The on-site analyses are performed either on a batch basis or on a routine basis using representative samples appropriate for the waste type.

Off-site analyses are used to establish scaling factors or other estimates for difficult to measure isotopes.

Note 5: Principle radionuclide refers to those radionuclides contained in the waste in concentrations greater than 0.01 times the concentration of the nuclide listed in Table 1 or 0.01 times the smallest concentration of the nuclide listed in Table 2 of 10 CFR 61.

Note 6: Type of waste is specified as described in NUREG 0782, Draft Environment Impact St:atement on 10 CFR 61 "Licensing Requirements 'for Land Disposal of Radioactive Waste".

Note 7: Type of container refers to the transport package.

1.0 Introduction This manual. describes methods which are acceptable for calculating radioactivity concentrations in the environment and potential offsite doses associated with liquid and gaseous effluents from the Turkey Point Nuclear Units. These calculations are performed to satisfy Technical Specifications and to ensure that the radioactive dose or dose commitment to any member of the public is not exceeded.

The radioactivity concentration calculations and dose estimates in this manual. are used to demonstrate compliance with the Technical Specifications required by 10 CFR 50.36. The methods used are acceptable for demonstrating operational compliance with 10 CFR 20.106, 10CFR50 Appendix I, and 40CFR190. Only the doses attributable to Turkey Point Units 3 and 4 are determined in demonstrating compliance with 40CFR190 since there are no other nuclear facilities within 50 miles of the plant. Monthly calculations are performed to verify that potential offsite releases do not exceed Technical Specifications and to provide guidance for the management of radioactive effluents. The dose receptor is described such that the exposure of any member of the public is not likely to be substantially underestimated.

Quarterly and annual calculations of committed dose are also performed to verify compliance with regulatory limits on offsite dose. For these calculations, the dose receptor is chosen on the basis of applicable exposure pathways identified in a land use survey and the maximum ground level atmospheric dispersion factor (X/Q) at a residence, or on the basis of more conservative conditions such that the dose to any resident near the plant is not likely to be underestimated.

2.0 Li id Effluents To provide calculational methodology needed to assure compliance with Technical Specification 3.11.1 which requires the following determinations and surveillances:

0 The concentration of radioactive materials released in liquid effluents.

0 The concentrations of radioactive materials released are maintained within the limits of Specification 3.11.1.1.

0 Quarterly and annual cumulative dose contributions to a member of the public from radioactivity in liquid effluents released from each unit to unrestricted areas are maintained within the limits of Specification 3.11 '.2 ~

0 Projected doses at least once per 31 days due to liquid releases-to unrestricted areas are maintained within the limits of Specification 3.11.1.3.

0 Operation of appropriate portions of the Liquid Radwaste Treatment System if projected doses exceed limits of Specification 3.11.1.3.

0 Verification of operability of Liquid Radwaste System by meeting Specifications 3.11.1.1. and 3.11.1.2.

2.2 Bases Radioactive liquid effluents from Turkey Point Units 3 and 4 are released through radiation monitors which provide an alarm and automatic termination of radioactive releases. There are three discharge points from the units: steam generator blowdown from each unit and a common radwaste monitor tank discharge.

The liquid effluent monitoring instrumentation and controls at Turkey Point for controlling and monitoring normal radioactive releases in accordance with Turkey Point Technical Specification 3.11.1. consist of the following:

2 ~2~1 Li id Radwaste S stem Potentially radioactive liquid waste from Units 3 and 4 chemistry laboratories, containment sumps, floor drains, showers and miscellaneous sources are collected in waste hold up tanks. These wastes are processed through a demineralizer system and the effluent stored in one of the three waste monitor tanks (Refer to Figure 2-1). Laundry wastes are normally segregated and sent to one of two monitor tanks. Liquid waste in the waste monitor tanks and

'onitor tanks are isolated and recirculated for a minimum of one(1) tank volume prior to sampling.

01/01/94

Liquids in these tanks are released after sampling and analysis in accordance with Technical Specification Table 4.11-1. The discharge from the waste monitor and monitor tanks is monitored by a radioactive liquid effluent monitor. Since these liquid effluents are a mixture from both Units 3 and 4, the measured releases from the common discharge point are apportioned to each unit as a ratio equal to the ratio of specific isotopic concentrations in the primary coolant of the two reactors to assure the effluents are within the allowable limits per reactor. $ n alternate method is to allocate effluent releases equally to both Units 3 and 4.

2~2 ~2 Steam Generator Blowdown Units 3 and 4 steam generator blowdown can be discharged directly from the blowdown flashtanks to the condenser cooling water mixing basin. The activity of each steam generator blowdown discharge (a composite) is monitored prior to the Blowdown Flash Tank for Unit 3 and 4 respectively. Releases from the steam generator blowdown are sampled and analyzed in conformance with Technical Specifi-

~

cation Table 4.11-1.

2 ' ' Storm Drains Storm drains from Units 3 and 4 discharge into both the circulating water intake and the condenser cooling water mixing basin. Storm drains are sampled and analyzed in accordance with Technical Specification Table 4.11-1.

2 ' ' Radioactivit Concentration in Li uid Waste The concentration of radionuclides in liquid waste is determined by sampling and analysis in accord-ance with Table 4.11-1 of the Technical Specifi-cations. If a radionuclide is below its LLD, and the calculated LLD concentration is below the LLD concentration value specified in Technical Specifi-cation, Table 4.11-1 then being present it is not reported as in the sample. When the radionuclide's calculated LLD is greater than the LLD.listed in Technical Specification Table 4.11-1, the calculated LLD should be assigned as the activity of the radionuclide.

01/01/94

2 ' 5 Radioactivit Concentration in Water at the Restricted Area Boundar Technical Specification 3.11.1.1 requires that the concentration of radioactive material, other than noble gases, in liquid effluent released into an unrestricted area not exceed 10 times the effluent concentration specified in 10 CFR Part 20, Appendix B, Table 2, Column 2. A maximum concentration, 2 x 10 4pCi/ml, for noble gas entrained in aqueous releases into an unrestricted area applies separately since the potential exposure route, immersion in water, differs from that upon which Part 20, Appendix B is based.

Radioactive material in liquid effluent from Turkey Point is diluted by condenser cooling water from fossil units 1 and 2 and from nuclear units 3 and 4 in the condenser cooling water mixing basin. Water in the basin flows into an onsite closed cooling canal system. Liquid effluent does not actually leave the site in a surface discharge. For the purpose of compliance with Technical Specification 3.11.1.1, the total condenser cooling water flow from operating condenser cooling water pumps at. the four units is assumed for dilution and the restricted area boundary is assumed to be at the end of the condenser'ooling water mixing basin where water enters the cooling canal system.

Sections 2.3.1 and 2.3.2 describe methods used to assess compliance with Technical Specification 3.11.1.1. Effluent monitor alarm/trip setpoints are computed on the same basis, as described in section 2.6. If an alarm/trip setpoint is not exceeded, aqueous effluents are deemed to comply with Technical Specification 3.11.1.1.

2.3 A eous Concentration The diluted concentration of radionuclides in the condenser cooling water mixing basin outflow is estimated with the equation

= Cg Fi Cg F2 01/01/94

where:

Cz) concentration of radionuclide i in the water in the condenser cooling water mixing basin outflow, (pCi/ml)

C,- concentration of radionuclide radwaste released, (pCi/ml) i in liquid F /F dilution F> = flow in radioactive liquid discharge line (gal/min) .*

F2 total condenser cooling water flow, (gal/min).* Value not greater than the rated total condenser cooling water flow from operating condenser cooling water pumps at the four units.

• F> and F> may have any suitable but identical units of flow, (volume/time) .

2~3~1 Batch Release A sample of each batch of liquid radwaste is analyzed before release for I-131 and other principal gamma emitters. With the activity concentration in a batch sample b based on the total isotopic. activity, the fraction of the unrestricted area EC due to a batch release is derived by using the ratio of the individual isotopic concentrations and their related ECs. FECb is estimated with the equation zi g ECg FEC~

where:

FECb fraction of the unrestricted area EC present in the condenser cooling water mixing basin outflow due to a batch release 01/01/94

C <

= i concentration of radionuclide in the water in the condenser cooling water mixing basin out flow, (pCi/ml); determined from equation (1) .

i of radionuclide according to 10 CFR 20, Appendix B, Table 2, Column 2, (pCi/ml).

(Quarterly average of the fraction of EC in the batch tank due to I-131 and principal gamma Eb emitters (Quarterly average of the fraction of EC in the batch tank due to all radionuclides measured.)

Eb is an adjustment to account for radionuclides not measured prior to release but measured in the quarterly sample per Technical Specification Table 4.11-1, i.e., Sr-89, Sr-90, Fe-

55. The value of Eb is calculated from previously measured data (a conservative value of 0.5 has been estimated for Eb a calculated value is not available), or FECb can be if calculated by including a previous quarter's beta C and EC<

into the calculation for each release, thus eliminating the Eb

<

factor.

Alternately, the fraction of the unrestricted area EC due to a batch release can be estimated by:

C FECb 1x10 (3) where:

C~ =

$ C,i(pCi/mi) 1 x 10 " unrestricted area EC for unidentified radionuclides in water, (pCi/ml).

2.3.2. Continuous Release Continuous aqueous discharges are sampled and analyzed according to the schedule in Technical Specification Table 4.11-1. 'he fraction of the unrestricted area EC present in a continuously discharged radioactive stream, FEC,, is derived from an isotopic analyses. The fraction of the unrestricted area EC can be derived using the ratio of the individual isotopic concentrations and their related ECs.

01/01/94

FEC, is estimated with the equation EC FEC C C

(4) where:

FEC fraction of the unrestricted area EC present in the condenser cooling water mixing basin outflow due to a continuous release Cxi concentration of radionuclide condenser i in the cooling water mixing basin water in the outflow determined from equation (1); (pCi/ml)

ECI Ten times the activity concentration limit in water of radionuclide i according to 10CFR20, Appendix B, Table 2, Column 2, (pCi/ml)

(Quarterly average fraction of EC due to I-131 and principal gamma emitters measured in samples E of continuous releases durin the uarter (Quarterly average fraction of EC due to all radionuclides measured in samples of continuous releases)

E is an adjustment to account for radionuclides not measured in individual samples of continuous releases but measured in the quarterly composite samples per Technical Specifications Table 4.11-1,i.e. Sr-89, Sr-90, Fe-55. The value of E, is calculated from previously measured data ( a conservative value of 0.5 has been estimated for E, if a can be calculated value is not available ), or FEC, calculated by including a previous quarter's beta C,< and EC,. into the calculation for each release, thus eliminating the E, factor.

Alternately, the fraction of the unrestricted area EC present in the condenser cooling water mixing basin can be estimated by FEC 1x10 (5)

Where:

01/01/94

1 x 10 ~ = unrestricted area EC for unidentified radionuclides in water, (pCi/ml) 2 ' ' Cumulative Release To ensure that the unrestricted area EC is not exceeded during periods of multiple releases, the fraction of EC determined for each type of release is summed to determine a total release fraction using the following equation:

FECz FEC~ + FEC~ (6)

Where:

FEC the total fraction of the unrestricted area EC released; FECb the fraction of the unrestricted area EC due to batch releases.e.g.monitor tanks, storm drains etc.

FEC the fraction of the unrestricted area EC due to continuous releases. e.g. steam generator blowdown.

2.4 Cumulative Dose Technical Specification 3.11.1.2 requires the dose or dose commitment to a member of the public from radioactive materials released in liquid effluents from each unit to unrestricted areas be limited to < 1.5 mrem to the whole body and 6 5 mrem to any organ during any calendar quarter and to

~ 3 mrem to the whole body and < 10 mrem to any organ during any calendar year.

Technical Specification 4.11.1.2 requires the dose or dose commitment to a member of the public due to radioactive material released in liquid effluent to be calculated on a cumulative quarterly and annual basis at least once per 31 days. The condenser cooling water basin and closed canal system which receives aqueous effluent is entirely on FP&L property, without surface discharge offsite, and FP&L does not 10 01/01/94

permit members of the public to use the water. As a result, potential exposure of a member of the public to radioactive material originating in aqueous effluent is limited to irradiation of persons by canal shoreline deposits.

Technical Specification 4.11.1.2 is satisfied by calculating the cumulative total body dose to a person who may be irradiated by radionuclides deposited on the cooling canal shoreline from radioactive liquid effluent. Compliance with the organ dose limit is assured as long as the total body dose is below its limit.

The model that is used to evaluate doses due to radioactivity in liquid effluents is Ashorellna Csk 'Fik k D 0 23 p p .

C)k the concentration of radionuclide in the undiluted liquid waste to be discharged that is represented by sample k, (pCi/ml)

F, liquid waste discharge flow during release represented by sample k, (gal/min) cooling canal effective volume, approximately 3.75 X 10~ gallons effective decay constant (A, + F>/V, min ').

where:

01/01/94

the radioactive decay constant Fz = canal-ground water interchange flow, approximately 2.25 x 10 gal/min tz = period of 'time (hours) during which liquid waste represented by sample k is discharged Radionuclide concentrations (C<z) in effluent are measured by the sampling and analysis program specified in Technical Specification Table 4.11-1. Typically, more than 90 percent of the potential irradiation from radionuclides deposited along the shoreline is due to Mn-54, Co-58, Co-60, Cs-134, and Cs-137. Of these radionuclides, Co-60 has the maximum dose transfer factor, A<. Thus, for the purpose of assessing compliance with Technical Specification, 4.11.1.2, the radioactive effluent source term may be either:

a) principal gamma emitters measured by the effluent sampling and analysis program, or b) Mn-54, Co-58, Co-60, Cs-134, and Cs-137 measured by the effluent sampling and analysis program and other identified gamma emitters assumed to be Co-60, or c) all gamma emitters measured by the effluent sampling and analysis program assumed to be Co-60.

Use of principal gamma emitters measured by the effluent sampling and analysis program is preferred over the other alternates.

2;5 Pro ected Dose Technical Specification 3.11.1.3 requires that the Liquid Radwaste Treatment System be operable and appropriate subsystems of the liquid radwaste treatment system shall be used to reduce the radioactive materials in liquid waste prior to their discharge when the projected doses from each unit to unrestricted areas due to liquid effluents, when averaged over a 31 day period, would exceed 0.06 mrem to the total body or 0.2 mrem to any organ.

Technical Specification 4.11.1.3.1 requires the doses, to unrestricted areas, due to radioactive material released in liquid effluent to be projected at least once per 31 days unless the liquid radwaste treatment .system is being fully utilized.

This requirement is satisfied by extrapolating the dose to date during the current month to include the entire month.

The dose to date is calculated as described in section 2.4.

The dose is projected with the relation:

12 01/01/94

P = 31'D X (8) where:

P = the projected total body or organ dose during the month, (mrem) .

31 = number of days in a calendar month, (days)

X = number of days in current month to date represented by available radioactive effluent sample, (days)

D = total body or organ dose to date during current month calculated according to section 2. 4, (mrem)

Alternately, the monthly dose may be projected by computing the doses to the total body and most exposed organ accumulated during the most recent month and assuming the result represents the projected doses for the cur'rent month. The dose during the preceding month will be computed as described in section 2.4.

2 ' Method of Establishin Alarm and Tri Set pints The radioactive liquid effluent monitoring instrumentation should be operable in accordance with Specification 3.3.3.5, with its alarm/trip setpoints set to ensure the limit of Specification 3.11.1.1 are not exceeded.

The alarm/trip setpoint for each liquid effluent radiation monitor is derived from 10 times the effluent concentration limits provided in 10 CFR Part 20, Appendix B, Table 2, Column 2 applied in the condenser cooling water mixing basin outflow.

Radiation monitoring and isolation points are located in the steam generator blowdown lines, R-3-19, R-4-19', and the liquid waste disposal system line, R-18, through which radioactive waste effluent is eventually discharged into the canal basin.

See Figure 2-1.

The alarm setpoint for each liquid effluent monitor is based upon the measurements of radioactivity in a batch of liquid to be released or in the continuous aqueous discharge. Sample measurements are performed according to Technical Specificat ion Table 4.11-1. If the calculated set:point is less than the existing setpoint, the setpoint shall be reduced to the new setpoint. If the calculated setpoint is greater than the existing setpoint, the setpoint may remain at the lower value or be increased to the calculated value.

0 Project the doses due to gaseous releases from each unit at least once per 31 days when gaseous radwaste treatment systems are not being fully utilized.

3.2 Bases Radioactive gaseous effluents from Turkey Point Units 3 and 4 are released through four monitored release points; a common plant vent via a stack above the containment building, the Unit 3 spent fuel pit vent, and the condenser air ejector vents from each unit. Unmonitored radioactive airborne releases can also occur from the secondary steam systems of each unit secondary leakage is occurring.

if primary to The effluent sources (refer to Figure 3-1) for each release point are tabulated in Table 3-1. The airborne releases from all these sources are treated as a mixed mode release from a single location for dose calculational purposes.

17 01/01/94

Compliance for beta and gamma dose limits at and beyond the site boundary for noble gas effluents is determined by assessing the dose rate and/or dose at the location where the minimum atmospheric dispersion occurs at the site boundary since the atmospheric dispersion will be higher at all other points off-site. This minimum dispersion occurs at the site boundary 1950 meters SSE of~

the plant where the dispersion factor is 5.8 x 10 sec/m .

The dose rate due to tritium, I-131, I-133, and radioactive particulates with half lives greater than 8 days at and beyond the site boundary is assessed by determining the dose rate to a hypothetical infant's thyroid via the inhalation pathway. The basis for this approach is NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants" which states: the dose factors are dependent on the specific organ and on the age group. The infant is the most restrictive age group for the dose rate calculations and the most restrictive organ is the thyroid via either the inhalation or grass-cow-milk pathway. The dose from tritium, I-131, I-133, and particulate is calculated by assuming a cow on pasture 4.5 miles west of the plant unless there is a milk producer in a more conservative location. At that location the reference ' atmospheric deposition factor, D/Q, is equal to 5 x 10 Sampling and analysis is performed as outlined in Technical Specification Table 4.11-2. Principle gamma emitters for batch gaseous effluents which are released via pathways (i.e. Plant Vent) with continuous radioiodine and particulate radionuclide sample trains are considered to be the Noble Gases.

3~2~1 Gaseous Radwaste S stem Radioactive and potentially radioactive gases from units 3 and 4 containment buildings, the auxiliary building, unit 4 spent fuel pit, radwaste building and laundry area are released via the monitored plant vent after passing through filter systems. Radioactive waste gases from the primary systems (CVCS hold-up tanks) are stored in gas decay tanks to reduce activity levels by radioactive decay prior to release via the plant vent. The unit 3 spent fuel pit area is ventilated via its'wn monitored vent after passing through a filtering system.'8 01/01/94

The steam jet air ejectors from each unit are vented through monitored release pathways. Other steam losses concurrent with primary to secondary leakage are unmonitored and gaseous activity must be accounted for.

3.2.2 Radioactivit in Gaseous Effluent Radionuclides other than noble gases in the gaseous effluents are measured by the radioactive gaseous waste sampling and analysis program described in Technical Specification Table 4.11-2. Noble gas radionuclides are measured by continuous monitors in the four release points. The gaseous effluent streams monitoring points, and effluent discharge points are illustrated schematically in Figure 3-1.

The measured radionuclide concentrations in gaseous effluents from the plant are used for estimating off-site radionuclide concentrations and radiation doses. Sampling and analyses are performed consistent with the require-ments of Technical Specification Table 4.11-2.

The radioactive iodines and particulate radionuclides from continuous releases and batch releases ( Containment Purges and Gas Decay Tanks are released via the Plant Vent ) are determined by charcoal and filter samples removed weekly from continuous sample trains installed at each release point (plant vent, condenser air ejectors and Unit 3 Spent Fuel Pit vent). Tritium activity is determined on monthly grab samples from the plant vent, condenser air ejector, and Unit 3 Spent Fuel Pit and by a grab sample from each containment purge.

Additional grab samples are obtained and analyzed if the conditions identified in Notes 4,5,6 and 7 of Technical Specification Table 4.11-2 exist, i.e., tritium grab samples once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the refueling canal is flooded, tritium grab samples at least weekly from the spent fuel pool ventilation exhaust when spent fuel is in the spent fuel pool, and sampling shall also be performed at least once per day for at least 7 days following each shutdown, startup or THERMAL POWER change exceeding 15%

analysis shows that the DOSE EQUIVALENT I-131 concentration in the primary coolant has increased by more than a factor of 3; and (2) the noble gas activity monitor shows that the effluent activity has increased by more than a factor of 3.

19 01/01/94

Activities measured by these additional samples should be included in the cumulative dose calculations.

Noble gas activity released is measured by continuous noble gas monitors installed in each discharge point for release types listed in Technical Specification Table 4.11-2. The quantity of radioactive noble gas activity not accounted for by grab samples can be determined by integrating the release rate measurement from each effluent noble gas monitor. The total measured radioactivity discharged via a stack or vent during a specific time period can be determined from the effluent monitors by:

Q)) quantity of radionuclide i released in a given gaseous effluent stream during counting interval j, (pCi) the fraction of radionuclide i released in a given effluent stream In the event the radioactive noble gas distribution is not obtainable from sample(s) taken during the current period the distribution will be obtained from recent data if available or from Table 3-2.

Some gaseous effluents from both Units 3 and 4, whose sources are .identified in Table 3-1, discharge in common through the plant vent. To assure that the effluents are within allowable limits per reactor, the measured release from the plant vent is apportioned to each unit on a ratio equal to the ratio of specific isotopic concen-trations in the primary coolant in the two reactors. An alternate method is to allocate effluent releases equally to both Units 3 and 4.

Iodine and particulate release contributions will also be adjusted to account for specific containment purge releases.

3.3 Dose Rate Due to Gaseous Effluent Technical Specification 3.11.2.1 provides that the dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site boundary shall be limited to the following: <500 mrem/year to the total body and 53000 mrem/year to the skin due to noble gases and <1500 mrem/year to any organ due to I-131, I-133, tritium and all radioactive materials in particulate form with half-lives greater than 8 days.

21 01/01/94

Compliance with the limits on dose rate from noble gases is demonstrated by establishing effluent monitor alarm setpoints such that an alarm will occur at or before a dose rate limit of the combined releases for noble gases is reached for the release types listed in Technical Specification Table 4.11-2.

If an alarm occurs when the monitor setpoint is at or below the limit, compliance may be assessed by comparing the monitor record with the setpoint (limit) calculated in accordance wi'th Section 3.6 or a more conservative method. In the event an alarm occurs and the monitored release exceeds the setpoint limit, then compliance shall be evaluated by calculating dose rates in accordance with Sections 3.3.1 and 3.3.2.

The alarm setpoints shall be derived on the basis of the radionuclide distribution from a measured gamma spectrum, a historical gamma spectrum dominated by Xe-133 or by assuming the total noble gas activity is Xe-133. If Xe-133 is the dominant radioactive gas in the airborne effluent, the gamma dose rate to a person's body is expected to be a larger fraction of the 500 mrem/year limit than is the sum of beta and gamma dose rates to the skin limit of 3000 mrem/year.

Thus, a gaseous effluent monitor setpoint may be derived on the basis of whole body gamma dose rate alone such that an alarm occurs at or before the whole body dose rate off-site exceeds 500 mrem/year as given in Technical Specification 3.11.2.1 ~

~ ~ Total Bod Dose Rate The total body dose rate from'adioactive noble gases may be calculated at any location off-site by assuming a person is immersed in and irradiated by a semi-infinite'cloud of the noble gases. The dose rate is calculated using the equation (13) where:

Since dose rate limits for airborne effluents apply everywhere off-site, compliance is assessed and alarm setpoints determined at the site boundary where the minimum atmospheric dispersion from the plant (maximum X/Q) occurs. Ordinarily, that location is selected on the basis of reference meteorology data in Table 3-6. According to those data, the minimum dispersion off-site occurs at the

3~3~2 Skin Dose Rate The dose rate to skin from radioactive noble gases may be calculated at any location off-site by assuming a person is immersed in and irradiated by a semi-infinite cloud of the noble gases. The dose rate to skin is calculated using the equation D~ +' g =gg'SP g+1.11+ Qg Ag'1 (14) where:

listed in Table 3-3 Since dose rate limits for airborne effluents apply everywhere off-site, compliance is assessed and alarm setpoints determined at the site boundary where the minimum atmospheric dispersion from the plant (maximum X/Q) occurs. Ordinarily, that location is selected on the basis of reference meteorology data in Table 3-6.

According to those data, the minimum dispersion off-site occurs at the site boundary 1950 meters SSE of the plant where X/Q = 5.8 x 10 ~ sec/m~. Alternately, averaged meteorology data coincident with the period of release being evaluated may be used.

When the dose rate due to H-3, I-131, I-133 and radio-nuclides in particulate form is calculated for . the purpose of assessing compliance with Specification 3.11.2.1, a hypothetical infant located where the minimum atmospheric dispersion from the plant occurs is assumed as the receptor.

For the radioiodines and particulates with half-lives greater than eight days, the effective dose transfer factor, TA, i, is based solely on the radioiodines (I-131, I-133). This approach was selected because the radioiodines contribute essentially all of the dose to the infant's thyroid via the inhalation and the grass-cow-milk pathway. The infant's thyroid via the inhalation pathway is the critical organ and controlling pathway respectively for the releases of radioiodines and particulates.

Ordinarily, the dose rate calculation will be based on the location of minimum dispersion adjusted for deposition according to the reference meteorology data in Table 3-7. According to those data, the minimum dispersion offsite occurs at the site boundary 19507 meters SSE of the plant and the X>/Q value is 5.0 x 10 sec/m~. That location is identified in Figure 3-2.

Alternately, averaged meteorological dispersion data coincident with the period of release may be used to evaluate the dose rate. These radionuclide concentrations in airborne effluents, Q,, are measured according to the sample and analysis scheclule in Technical Specification Table 4.11-2.

3.4 Dose-Noble Gases Technical Specification 3.11.2.2 requires that the air dose per reactor at and beyond the site boundary due to noble gases released in gaseous effluents shall be limited during any calendar quarter, to <5 mrad for gamma radiation and <10 mrad for beta radiation and during any calendar year, to <10 mrad for gamma radiation and <20 mrad for beta radiation.

Alternately, Specification 4.11.2.2 may be satisfied by calculating the gamma dose to air with the equation (17) where:

3.5 Dose Due to Iodine Tritium and Particulates in Gaseous Effluents Technical Specification 3.11.2.3 requires the dose per reactor to a member of the public due to I-131, I-133, tritium, and particulates with half-lives greater than 8 days in airborne effluents released to areas at or beyond the site boundary shall not exceed 7.5 mrem to any organ during any calendar quarter and shall not exceed 15 mrem to any organ during any calendar year.

3' ~ 1 Determinin the uantit of Iodine Tritium and Particulates Radionuclides, other than noble gases, in gaseous effluents that are measured by- the radioactive gaseous waste sampling and analysis program described in Technical Specification Table 4.11-2 are used as the release term in dose calculations. Airborne releases are discharged either via a stack above the top of the containment building or via other vents and are treated as a mixed mode release from a single location. Releases of steam from the secondary system concurrent with primary to secondary leakage will also result in the release of activity to the atmosphere. For steam generator blowdown, using a blowdown sample analysis, it is assumed that 54 of the I-131 and I-133 and 334 of the tritium in the blowdown stream become airborne with the remainder staying in the liquid phase. For other unmonitored releases, the quantity of airborne releases may be det-ermined by performining a steam mass balance.

For each of these release combinations, samples are analyzed weekly, monthly, quarterly, or for each batch releases according to Table 4.11-2.

Each sample provides a measure of the concentration of specific radionuclides, C<, in gaseous effluent discharged at flow, F, during a time increment, ~t. Thus, each release is quantified according to the relation 0~~= C~~'P Fg'a tg (20) 29 01/01/94

ML the measured mass of watex discharged from the secondary system as liquid during time interval ~t>. e.g. steam generator blowdown.

M the measured mass of steam or non-condensible gases discharged from the secondary system during time interval at, e.g. air ejector discharge.

Note: it is assumed that all of the I-131, I-133 and tritium in the other unmonitored releases are discharged as airborne species. It also assumed that gm/sec is equivalent to cc/sec.

30 01/01/94

3 ' ' Calculatin the Dose Due to Iodine Tritium and Particulates A person may be exposed directly to an airborne concentration of radioactive material discharged in an effluent gaseous stream and indirectly via pathways involving deposition of radioactive material onto the ground. Dose estimates should account for the exposure via the following pathways:

0 direct radiation from airborne radionuclides except noble gases 0 inhalation 0 direct radiation from ground plane deposition 0 fruits and vegetables 0 air-grass-cow-meat 0 air-grass-cow-milk Of all these pathways, the air-grass-cow-milk pathway is by far the controlling dose contributor.

The radioiodines contribute essentially all of the dose, by this pathway, with I-131 typically contributing greater than 954. The dose transfer factors for the radioiodines are much greater than for any of the other radionuclides. The critical organ is the infant's thyroid. For this reason, the potential critical organ dose via airborne effluents can be estimated by determining an effective dose transfer factor for the radioiodines based on the typical radioactive effluent distribution, the air-grass-cow-milk pathway, and the infant thyroid as the receptor. Then for conservatism the total cumulative release of all radioiodines and particulates can be used along with the effective dose transfer factor to determine a conservative estimate of the infant thyroid dose.

Technical Specification 4.11.2.3, requires an evaluation be performed once per 31 days to verify that the accumulated total body or organ dose for the current calendar quarter and calendar year does not exceed the limit as given in 3.5. Dose commitment due to iodines aad particulates may be calculated by using the following equation

At that location the reference atmos-pheric deposition factor is D/Q = 5 x 10 m When equation 22 is used to estimate the critical organ dose commitment, the effective dose transfer factor is:

4. Determination of the Projected Dose (Section 2.5)

The dose, to unrestricted areas, from liquid effluent must be projected at least once per 31 days when the liquid radwaste treatment system is not being fully utilized. The dose projection can be made using equation (8).

31 'D X (8) where:

P = the projected total body or organ dose during the month (mrem) 31 = number of days in a calendar month, (days)

X = number of days in current month to date represented by available radioactive effluent sample, (days)

TURKEY POINT OFFSITE DOSE CALCULATION MANUAL BASIS DOCUMENT

1.0 Introduction The operation of a nuclear facility is regulated by requirements contained in the Code of Federal Regulations (CFR's). Section 50.36 of 10CFR50 requires that each nuclear power reactor operating license contain technical specifications that describe limits, operating conditions and other regulatory requirements imposed on the facility operation for protection of the health and safety of the public. At each site, conditions and limitations which are system dependent and site related must be incorporated in the technical specifications. These technical specifications are submitted to the Nuclear Regulatory Commission as part of the licensing process and upon approval are included in Appendix A of the facility operating license.

Technical specifications for a nuclear power plant require the operator to establish alarm and trip setpoints for each liquid and gaseous effluent release point. In addition, these setpoints must be maintained in auditable records and be determined in accordance with an Offsite Dose Calculation Manual (ODCM). The ODCM must also include the methodology and parameters used in the calculation of offsite doses due to radioactive liquid and gaseous effluents.

01/01/94

2.0 Offsite Dose Calculation Manual Methodolo The Nuclear Regulatory Commission (NRC) has developed dose calculation methodology which the NRC considers acceptable for use in the ODCM. The NRC guides are:

Regulatory Guide 1.109 "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I" (Revision 1),

October 1977.

Regulatory Guide 1.110 "Cost-Benefit Analysis for Radwaste Systems for Light-Water-Cooled Nuclear Power Reactors," March 1976.

Regulatory Guide 1.111 "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors" (Revision 1), July 1977.

Regulatory Guide 1.112 "Calculation of Releases of Radioactive Materials in Gaseous and Liquid Effluents from Light-Water-Cooled Power Reactors,"

April 1976.

Regulatory Guide 1.113 "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I" (Revision 1),

April 1977.

The NRC has also developed computer codes which may be used with these guides. The codes are:

NUREG-0017 "Calculation of Releases of Radioactive Materials in Gaseous and Liquid Effluents from Pressurized Water Reactors (PWR-GALE Code)," April 1976.

NUREG-0324 "XOQDOQ, Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations," September 1977.

NUREG-0133 Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," October 1978.

01/01/94

Conformance with the NRC guidelines for dose calculation methodology is not required. However, if different mathematical models and parameters are used to calculate set points, release rates or dose estimates, the parameters and calculations used shall be substantiated in the ODCM.

The Turkey Point ODCM uses equations and models adopted from the methodology provided in the regulatory guides.

4.0 Li ui Radwaste Releases Liquid radwaste from Turkey Point Nuclear Units 3 and 4 are discharged to the condenser cooling water mixing basin which in turn discharges to a closed cooling loop water canal system. Liquid radwaste releases may be discharged in batches from holding tanks, continuously from steam generator blowdown or through storm drains. Radwaste entering the mixing basin is mixed with and diluted by condenser cooling water from Fossil Units 1 and 2 and Nuclear Units 3 and 4 before being discharged to .the canal.

At Turkey Point, all liquid radwaste are sampled and analyzed in accordance with Technical Specification Table 4.11-1. In addition, batch and continuous release are continuously monitored by in-line radiation monitors during release.

Storm drain releases are not continuously monitored.

4.1 Technical Specifications for Liquid Effluents The following Technical Specification requirements must be met when releasing radioactive liquid effluents and the methodology for calculating the specifications must be contained in the ODCM.

4.1.1 Liquid Effluent Concentrations Technical Specification 3.11.1.1 requires that the radioactive concentration of liquid effluents discharged to the Unrestricted Area be limited to 10 times the radionuclide Effluent Concentrations (ECs) given in 10CFR20, Appendix B Table 2, Column 2 for radionuclides other than dissolved4 or entrained noble gases. A separate EC of 2x10 pCi/ml is given for noble gases dissolved or entrained in liquids.

For purposes of implementation at Turkey Point, the Unrestricted Area for liquid effluents begins where the water from the mixing basin enters the cooling canal.

The methodology for satisfying Technical Specification 3.11.1.1 is provided in ODCM equations 1 to 6. In addition to providing the required calculational techniques, some of these equations contain conservative factors to ensure that the requirements of Technical Specification 3.11.1.1 are not exceeded.

01/01/94

4.1.1.1 Diluted Radwaste Concentrations Diluted radwaste concentrations are determined using ODCM equation 1:

Cg=

Z Cg-F~

p2 where:

C. = concentration of radionuclide water in the condenser cooling water i in the mixing basin outflow, (pCi/ml).

C; concentration of radionuclide radwaste released, (pCi/ml) .

i in liquid Fi/Fq = dilution.

F> = flow in radioactive liquid discharge line (gal/min).*

total condenser cooling water flow, (gal/min).* Value not= greater than the rated total condenser cooling water flow from operating condenser cooling water pumps at the four units.

• F) and F> may have any suitable but identical units of flow, (volume/time) .

This equation is a simplification of the completely mixed model given in Regulatory Guide 1.113 for impoundments. As used at Turkey Point this equation provides conservative estimates of diluted radionuclide concentrations because:

The volume of the mixing basin and the canal are not included in the total volume.

The effects of radioactive decay are ignored.

10 01/01/94

In practice, the equation is used in the following way:

To make pre-release estimates. These estimates are made using condenser cooling water flows from the nuclear units only as total flow (F>)

because cooling water flow for the fossil units is regulated by the Fossil Plant control room and may change during the period of release.

To make post release estimates. These estimates are made using cooling water from both the fossil and the nuclear units as total flow (F>). In general, post release estimates are less than or equal to pre-release estimates.

In addition to radioactive decay., ODCM equation 1 also ignores the rate of buildup of long-lived isotopes. Regulatory Guide 1.113 expresses this rate as:

W C

where:

C = steady state concentration of non-decaying substances.

w = the rate of addition of radioactivity qz = pond blowdown or volume removal factor Because of the closed nature of the cooling canal at Turkey Point, the only loss or removal factor (q~) is evaporation which effects only volatile radionuclides and since, except for seasonal variations, the volume in the cooling canal remains relatively constant the rate of buildup maybe expressed as:

C0 = w In other words the rate of buildup is equivalent to the steady state concentration at any point in time.

01/01/94

4.1.1.2 Effluent Concentrations (ECs)

Liquid radwaste activity release concentrations are determined by using ODCM equations 2 to 6.

Equations 2, 3, 4 or 5 provide methods for determining the fractions of the EC in batch or continuous releases. Equation 6 provides a means of totalling the fractional ECs from all releases.

Equations 2, 3, 4 and 5 are simple fractional equations which compare the measured released concentrations of radionuclides in effluents to the limit or EC. For conservatism, the resulting fraction is further divided by an adjustment factor to account for radionuclides released but not measured prior to release. Since these equations are simple ratios, they are not directly related to or derived from the modeling equations used in the Regulatory Guides.

4.1.1.2.1 ODCM Equations 2 and 4 These two equations use the diluted nuclide concentration (C.) from ODCM equation 1 and 10 times the EC values for individual nuclides, i (EC,.)

from 10CFR20, Appendix B, Table 2, Column 2 to determine the fraction of EC for individual nuclides (FEC) present in the cooling water mixing basin as a result of batch (FEC>) and/or continuous releases (FEC,). The equation(s) are:

EC~

FECb(c) (2/4) b(c) where:

FECb(c) the fraction of the unrestricted area EC present in the condenser cooling water mixing basin outflow due to batch (b) or continuous (c) releases.

the concentration of a radionuclide, Z(

i, in the condenser cooling water mixing basin outflow.

12 01/01/94

10 times the activity concentration EC, limit in water of radionuclide according to 10CFR20 Appendix B i

Table 2, Column 2 (pCi/ml)

Quarterly average of FEC in the batch tank (b) or continuous release (c) due to I-131 and principal gamma b(c) emitters.

Quarterly average .of FEC in the batch tank (b) or continuous release (c) due to all radionuclides measured.

The term Ez<,> is an adjustment to account for radionuclides such as Sr-89, Sr-90, Fe-55 etc.

which are not. measured prior to release but are measured in quarterly samples per Technical Specification Table 4.11-1. The value of E><,> is calculated from previously measured data.

calculated data is not available, historical values If may be used. Historical data quarterly analysis have established a value for E of about 0.8. To ensure conservatism and to allow for occasional

< >

concentrations which exceed the historical value, a value of 0.5 can be used as an alternative for Ez<,>.

Alternatively, the E~,> factor can be eliminated by including a previous quarter's beta activity and Ec values into the calculations for each release. The addition of these values corrects for unmeasured activity making the E<,> factor redundant and not required.

4.1.1.2.2 ODCM Equations 3 and 5 These two equations are an alternate means of determining the fraction of EC for a batch (b) or (c) continuous release. The equation(s) are:

13 01/01/94

C FZCb(c) (3/5) 1 ~10 where:

Cb(c) g c 1x 107 ten times the unrestricted area EC for unidentified radionuclides in water from 10CFR20 Appendix B Table 2 ~

Equation 3/5 differs from equation 2/4 as follows:

A gross value for radionuclides in water of 1 x 10 7 pCi/ml is used instead of EC values for individual radionuclides (i).

The diluted concentrations (C,<) of individual radionuclides are summed to produce a gross activity value.

There is no adjustment for radionuclides not measured prior to release but measured in the monthly and quarterly samples.

As a result, the alternate equations 3/5 will generally yield fractional EC values that are less conservative than equations 2/4.

4.1.1.2.3 ODCM Equation 6 This equation is used to sum all of the fractional EC's to provide a cumulative total from all release paths, since simultaneous liquid radwaste releases may be occurring from several sources. This equation accounts for simultaneous releases from:

Batch tanks.

Continuous releases from Units 3 and 4.

01/01/94

The equation does not account for releases from storm drains although this release pathway may be considered a batch release and its contribution determined from monthly sample results.

4.1.2 Dose to a Member of the Public Technical Specification 3.11.1.2 requires that the dose or dose commitment to a Member of the Public from radioactive materials in liquid effluents released from During any calendar quarter 1.5 mrems to the whole body

< 5.0 mrems to any organ During any calendar year

< 3.0 mrems to the whole body

< 10.0 mrems to any organ The methodology for satisfying Technical Specification 3.11.1.2 is provided in ODCM equation 7. This equation considers only irradiation from shoreline as a dose factor at Turkey Point because of the nature of the cooling canal and restrictions on access to the site. At Tuz'key Point, both the condenser cooling water mixing basin and the closed loop cooling canal system are located entirely on FP&L property. Cooling water leaving the plant circulates through the canal system and returns to the plant cooling water inlet without offsite discharge. Since FP&L limits access to the canal and does not permit members of the public to use the water for drinking, bathing, gardening or any other purpose determination of dose is simplified. Dose factors that are important at other sites such as use of the water for drinking and gardens; the consumption of fish and shellfish etc. may be, ignored at Turkey Point. Public access is limited by FP&L to occasional use of areas near the canal for camping by scout troops. As a result, the potential exposure of a member of the public to radioactive material in liquid effluent is limited to irradiation of campers by canal shoreline. deposits.

This equation determines dose by combining the summed quantities of individual radionuclides,i for three discrete terms.

0 The term A< referred to as a transfer factor is a site related ingestion dose commitment factor to the total body or any organ for each identified principal gamma and beta emitter. The term A< is an adaptation of ingestion dose data contained in Regulatory Guide 1.109 Appendix B.

The other terms are related to specific site and radionuclide criteria for a given release of liquid effluent. In practice at Turkey Point only the dose to the whole body is determined because if this dose is within specification, organ dose will be below its limit.

4.1.3 Projected Dose Technical Specification 4.11.1.2 requires that cumulative dose contributions from liquid effluents for the current calendar quarter and current calendar year shall be determined in accordance with the methodology and parameters in the ODCM at least once per 31 days.

In addition, Technical Specification 3.11.1.3 requires that the Liquid Radwaste Treatment system shall be

~0 erable and appropriate portions of the system shall be used to reduce releases of radioactivity when the ro'ected doses due to the liquid effluent from each unit to the Unrestricted areas would exceed 0.06 mrem to the whole body or 0.2 mrem to any organ when averaged over a 31 day period.

Technical Specification 4.11.1.3.1 requires that doses due to liquid releases from each unit to Unrestricted Areas shall be projected at least once per 31 days in accordance with the methodology and parameters in the ODCM when the Liquid Radwaste Treatment Systems are not being fully utilized.

At Turkey Point, the Technical Specification requirements are satisfied with ODCM equation 8. The dose is projected with the relation:

P = 31'D X

(8) where:

P the projected total body or organ dose during the month, (mrem) 31 number of days in a calendar month, (days) number of days in current month to date represented by available radioactive effluent sample, (days) 17 01/01/94

D = total body or organ dose to date during current month calculated according to ODCM dose equations, (mrem)

Alternately, the monthly dose may be projected by computing the doses to the total body and most exposed organ accumulated during the most recent month and assuming the result represents the projected doses for the current month.

This equation is a simplification of dose projection equations descr'ibed in Regulatory Guide 1.109 and NUREG-0133.

4.1.4 Effluent Monitor Setpoints Technical Specification 3.3.3.5 requires that liquid effluent monitoring instrumentation channels be ~o erable with their alarm/trip setpoints set to ensure that the limits of specifications 3.11.1.1 are not exceeded. The alarm/trip setpoints of these channels shall be determined and adjusted in accordance with the methodology and parameters in the ODCM.

The requirements of this Technical Specification are met by using ODCM equations 9 and 10. These equations are:

The setpoint equation(s) used at Turkey Point are derived from setpoint determinations provided in NUREG-0133 Addendum. The general equation has been altered to include a safety factor. This factor was added because there is a possibility of continuous releases from Units 3 and 4 occurring at the same time as a batch release.

5.0 Gaseous Radwaste Releases Gaseous radwaste releases from Turkey Point Nuclear Units 3 and 4 are discharged from four monitored release points.

These release points are:

A common plant vent Unit 3 spent fuel pit vent Unit 3 and 4 air ejector vents ln addition, unmonitored gaseous releases occur from six release points in the Unit 3 and Unit 4 secondary system.

These release points are:

Blowdown flash tanks (2)

~

Hogging jet exhausts (2)

Water box priming jets (2)

Releases from the unmonitored points can result in discharges of radioactive gases if primary to secondary leakage occurs.

For calculational purposes, airborne releases from all discharge points are treated as a mixed mode, ground level release from a single location. .The equations used for calculating gaseous release rates, atmospheric dispersion, dose rates and radiation monitor setpoints are adapted from models and equations given in regulatory guides and NUREG's.

The principal references used in the Turkey Point ODCM for radioactive gaseous releases are Regulatory Guides 1.109 and 1.111 and NUREG-0133.

The standard technique is to use Turkey Point meteorological data from daily measurements and/or historical data with models from the regulatory guide to provide atmospheric dispersion factors for the plant. These dispersion factors are determined in 16 compass directions from the plant release point to locations within, at and beyond the site boundary.

Because there are physical and chemical differences between the noble gases, radioiodines, tritium and particulates being released and dispersed in gaseous effluents, there are three dispersion factors which must be determined, these are referred to as:

The atmospheric dispersion factor (I/Q)

The atmospheric dispersion factor adjusted for depletion by deposition (X/Q)

,.The relative deposition rate onto ground (D/Q) 5.1 Technical Specifications for Gaseous Effluents The following Technical Specification requirements must be met when releasing radioactive gases and the 20 01/01/94

methodology for calculating releases must be contained in the ODCM.

5.1.1 Gaseous Effluent Dose Rates Technical Specification 3.11.2.1 requires that the dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site boundary shall be limited to the following:

Noble Gases 5 500 mrem/yr to the whole body 3000 mrem/yr to the skin I-131, I-133, Tritium and Particulates with half lifes greater than 8 days.

1500 mrems/yr to any organ The requirements of the specification reflect the differences between the behavior of noble gases as opposed to radioiodines, tritium and particulates. As a result of these differences, several equations are required in the ODCM to estimate the quantities of radionuclides released and the dose rate. The

.methodology for satisfying Technical Specification 3.11..2.1 is provided in ODCM equations 11 to 15.

5.1.1.1 Noble Gas Activity Release Quantities

~

The total measured quantity of noble gas activity released via a stack or vent during a specific time period can be determined using the appropriate gaseous effluent monitor data as follows:

N 'F g= ~'h (11) 3.53x10 where:

total measured gross gaseous radioactivity release via a stack or vent during counting interval j, (pCi)

N,. = counts accumulated during counting interval j, (counts = N(cpm) x t(min) )

effluent noble gas monitor calibration or counting rate response )for noble gas gamma radiation, ( ~cm )

pCi/cm The distribution of radioactive noble gases in a gaseous effluent stream is determined by gamma spectrum analysis of gas samples from that stream.

Results of previous analyses may be averaged to obtain a representative distribution.

If f< represents the fraction of radionuclide i in a given effluent stream, based on the isotopic distribution of that stream, then the quantity of radionuclide i released in a given gaseous effluent stream during counting interval j is:

Q, ~ = Q (12)

,JJ J 1 where:

Q< J i quantity of radionuc lide released in a given gaseous effluent stream during counting interval j, (pci) f< = the fraction of radionuclide i released in a given effluent stream Equation 11 is an efficiency correction equation which converts the relative counts of a radiation monitor to an absolute release activity using the known monitor efficiency to make the conversion.

If a gamma spectrum analysis is available for the noble gases in a release, the relative ratios of the gases in the spectrum may be used to convert the gross activity, Q. from equation 11 to specific radionuclide (i) activity as shown in equation 12.

If a gamma spectrum is not available, historical noble gas activities may be averaged to produce release fractions for noble gases. These release fractions from historical Turkey Point noble gas data are given in ODCM Table 3-2.

22 01/01/94

5.1.1.2 Noble Gas Total Body Dose Rate The total body dose rate due to 'noble gas releases is determined using the following equation:

D>> = 7 ~ 1 gx P (13) where:

D,s = Dose rate to total body from noble gases, (mrem/year) atmospheric dispersion factor at the off-site location of interest, (sec/m~)

t = averaging time of release, increment of time during which Q,. was i.e.,

released, (year)

Q,. = quantity of noble gas radionuclide released during the averaging time, (pCi) i P TI factor converting time integrated concentration of at ground-level noble to total gas radionuclide body dose, i

pCi sec/m Equation 13 is an adaptation of the total body dose rate equations from Regulatory Guide 1.109. The atmospheric dispersion factor(s) g/Q were developed from Turkey Point Meteorological data collected during calendar years 1976 and 1977 and atmospheric models from Regulatory Guide 1.111. The air dose transfer factor P,. is derived from Regulatory Guide 1.109 Table B-1. Factors required for Turkey Point calculations are contained in ODCM tables. The factor(s) X/Q is contained in ODCM Table 3-6 and the factor(s) P,. in ODCM Table 3-4.

This equation assumes that the person subjected to the dose rate from noble gases is immersed in a semi-infinite cloud of the gases, which infers immersion in gases that are totally mixed and present at some uniform concentration. The limiting case for total body dose rates at or beyond the site boundary is the location at the 23 01/01/94

site boundary where the highest concentration of radioactive noble gases occurs. This location will be the point or quadrant where g/Q data indicate that atmospheric dispersion is at a minimum.

Present data indicate that minimum dispersion occurs at the site boundary 1950 meters SSE of the plant where X/Q is equal to a value of 5.8 x 10 7 sec/m . This value will be used in equation 13 to determine total body dose rates from noble gases unless subsequent X/Q data indicate that the minimum dispersion value and/or location at the site boundary has changed.

5.1.1.3 Noble Gas Skin Dose Rate The skin dose rate due to noble gas releases is determined using the following equation:

D = +'.1 P gg'Span+1. 1lg gg'Ag (14) where:

for gamma and beta doses respectively are derived from Regulatory Guide 1.109 Table B-1. The factor(s) A,. is contained in ODCM Table 3-3 and the factor S~,. in ODCM Table 3-4.

This equation also assumes a person immersed in a semi-infinite cloud of noble gases at the site boundary where minimum atmospheric dispersion occurs. As in equation 13, this location is 1950 meters SSE of the plant where g/Q is equal to a value of 5.8 x 10 ~ sec/m~.

5.1.1.4 Tritium, I-131, I-133 and Particulate Dose Rate The dose rate due to tritium, I-131, I-133 and particulates with a half-life greater than 8 days released in gaseous effluents is determined with the following equation:

This equation uses historical g</Q values which are given in ODCM Table 3-7 and are derived 25 01/01/94

from Turkey Point historical meteorological data and the atmospheric models contained in Regulatory Guide 1.111. The dose transfer factor TA

>> is based solely on the g radioiodines (I-131, I-133) because the radioiodines contribute essentially all of the dose to the infant's thyroid. The limiting case for the dose rate due to iodine, tritium and particulates at or beyond the site boundary is the location at the site boundary where there is minimum dispersion adjusted for deposition. Present data from ODCM Table 3-7 indicate that minimum dispersion adjusted for deposition, X</Q, occurs at the site boundary 1950 meters SSE of the plant where the X</Q value is 5.0 x 10'ec/m'. 5.1.2 Gaseous Effluent Dose From Noble Gases Technical Specification 3.11.2.2 requires that the air dose er reactor at and beyond the site boundary due to noble gases in gaseous effluents shall be limited to: 26 01/01/94 During any calendar quarter g 5 mrad for gamma radiation 10 mrad for beta radiation During any calendar year 10 mrad for gamma radiation g 20 mrad for beta radiation In addition, Technical Specification 4.11.2.2 requires that the cumulative gamma and beta radiation dose be determined at least once per 31 days to verify that accumulated air dose due to gamma radiation and beta radiation does not exceed the limits for the current quarter and year. 5.1.2.1 Noble Gas Gamma Radiation Dose The gamma radiation dose is calculated with the following equation: . Qy s + ~ g o gg (1l ) J where: D noble gas gamma dose to air due to a mixed mode release, (mrad) 0.8 a conservatism factor which, in effect, increases the estimated dose to compensate for variability in radionuclide distribution atmospheric dispersion factor for a mixed mode discharge, (sec/m~) yeff effective gamma air dose factor converting time-integrated, ground-level, total activity concentration of radioactive noble gas, to air dose due to, gamma radiation. This factor has been derived from noble gas radionuclide distributions in - routine operational releases. The effective gamma air dose factor is: ( ,.. mrad ...g. ) 27 01/01/94 the measured gaseous radioactivity released via a stack or vent during a single counting interval j, (pCi) Equation 16 is derived from dose equations for noble gas gamma activity in Regulatory Guide 1.109. The measured gross activity value, Qj is determined using ODCM equation 11. The atmospheric dispersion factor X/Q was developed from Turkey Point historical meteorological data using Regulatory Guide 1.111. Turkey Point g/Q data are given in ODCM Table 3-6. The conservatism value, 0.8, is based on Turkey Point historical noble gas data. This historical variability has been observed in both liquid and gas samples. In the case of liquids, the conservatism value was further reduced to 0.5 because of higher uncertainty of mixing in the liquids. The effective gamma air dose factor, A,<<, is based on historical Turkey Point noble gas data collected during the years 1978, 1979 and 1980. The technical basis for A),ff is described in the ODCM Appendix B. The limiting case for gamma dose from noble gases occurs at the location on the site boundary where minimum atmospheric dispersion, X/Q, occurs. At Turkey Point, this location is at the site boundary 1950 meters SSE of the plant where the X/Q value is 5.8 x 10 sec/m . 5.1.2.2 Noble Gas Beta Radiation Dose The beta radiation dose is calculated with the following equation: (18) where: D~ = noble gas beta dose to air due to a mixed mode release, (mrad) 0.8 a conservatism factor which, in effect, increases the estimated dose to compensate for variability in radionuclide distribution 28 01/01/94 Seff effective beta air dose factor converting time-integrated, ground-level, total activity concentration of radioactive noble gas to air dose due to beta radiation. This factor has been derived from noble gas radionuclide distributions in routine operational releases. The effective beta air dose factor is: A ff = 3.4 x 10 mrad pCi sec/m ) This equation is identical in format to equation 16, except the effective beta air dose factor Aff has been substituted for A eff to determine noble gas beta dose. The technical Basis for the term A8eff is described in the ODCM Appendix B. Beta doses are also calculated for the location on the site boundary where minimum dispersion occurs, this location is 1950 meters SSE of the plant where X/Q equals 5.8 x 10 7 sec/m~. 5.1.2.3 Alternate Noble Gas Radiation Dose Calculations The gamma and beta radiation doses from noble gases may also be calculated using the following equations: v Y 0 ZZ~f ~ v~ (17) Dp = +P Q P gg'Zg'Apg (19) p where: the fraction of radionuclide in a given effluent stream i released Af factor converting time integrated, ground level concentration of noble gas radionuclide i to air dose from gamma radiation, mrad pCi ~ ~ sec/m ) 29 01/01/94 0 Asi factor converting time-integrated, ground level concentration of noble gas radionuclide i to air dose from beta radiation, mrad ...g. ) The 'difference between these equations and equations 16 and 18 is that A and A~ are calculated (A,- f,.) for each analysis~ ffas descrNed in < ODCM Appendix B. Since the factors are determined on each set of analysis data, the conservatism factor, 0.8 is not included in the equations because variability in the radionuclide distribution is reflected in sample analysis data.

5. 1. 2. 4 Cumulative Noble Gas Gamma and Beta Radiation Dose Determinations The cumulative gamma and beta radiation dose determinations required by Technical Specification 4.11.2.2 is satisfied by summing all the noble gas analysis performed on samples taken during releases using equations 16 or 17 and 18 or 19.

5.1.3 Gaseous Effluent Dose From Iodine, Tritium and Particulates Technical Specification 3.11.2.3 requires that the dose to a member of the public from I-131, I-133, tritium and all radionuclides in particulate form with half-lifes greater than 8 days in gaseous effluent released from each unit to areas at and beyond the Site Boundary shall be limited to: During any calendar quarter 5 7.5 mrems to any organ and During any calendar year < 15 mrems to any organ In addition, Technical Specification 4.11.2.3 requires that cumulative dose contributions during the current calendar quarter and current calendar year be determined at least once per 31 days. 5.1.3.1 Iodine, Tritium and Particulate Activity Release Quantities 30 01/01/94 The quantity of iodine, tritium and particulate activity released in gaseous effluents is determined with the following equation: (20) where: the quantity of radionuclide in a given effluent stream i released based on analysis k, (pCi) C<k = concentration of radionuclide gaseous effluent identified by analysis i in a k, (pCi/cc) F,. = effluent stream discharge rate during time increment htJ, (cc/sec) time increment radionuclide i j during which at concentration C,.k is being discharged, (sec). Equation 20 is an integration equation used to 'determine the .total activity entering the atmosphere at a known flow for a measured period of time. The term C,.k is the concentration values from sampling and analysis performed in accordance with Technical Specification Table 4.11-2 using weekly, monthly and/or quarterly analysis results. The value of C<k may have to be adjusted, changing the value of Q,.k under certain circumstances. During normal operations, gaseous releases from stacks and vents require no adjustment of the term C<>. However, if primary to secondary leakage ~fs occurring radioactivity will be released to the atmosphere via gaseous releases from the secondary system. Under these circumstances C,.k is determined by sampling steam generator blowdown and assuming that 5% of the I-131 and I-133 and 33% of the tritium in the blowdown stream becomes airborne with the remainder staying in the liquid phase. This assumption has been validated during historical measurements of the blowdown liquid and steam phases. 31 01/01/94 For other unmonitored releases, the quantity of airborne releases may be determined by performing a steam mass balance using the following equation: Fg = M~ (M~+Mq) (21) where: the measured mass of makeup water .entering the secondary system during time interval ~tj. e.g. steam generator shutdown. ML the measured mass of water discharged from the secondary system as liquid during time interval ~tj. e.g. steam generator blowdown. MS the measured mass of steam or non-condensible gases discharged from the secondary system during time interval ~tj. e.g. air ejector discharge. Equation 21 is a simple balance equation comparing input to losses. This equation assumes that when the water injected into the secondary system as makeup (M) is equal to the rate of known discharges of steam and gases (Ms) and liquid (M) that the discharge from the secondary system (F-) will be zero. When F,. is a value greater than zero, assumed that the release rate is due to other it is unmonitored releases. For purposes of determining doses due to iodine, tritium and particulates it is further assumed that these other releases are as steam and their concentrations (C><) are the same as their concentrations in steam generator blowdown samples. This assumption is valid because of the large temperature and pressure differences between the operating secondary system and the ambient environment. Equation 20 is a great simplification of the complex mass balance equations in NUREG 1.109. 5.1.3.2 Determining Dose Due to Zodine, Tritium and Particulate Gaseous Releases Doses from iodine, tritium and particulates discharged in gaseous effluents can result in exposure to a person by several pathways. These pathways are: 32 01/01/94 Direct radiation from airborne radionuclides except noble gases Inhalation Direct. radiation from ground plane deposition Fruits and vegetables Air-grass-cow-meat Air-grass-cow milk Research, field studies and modeling indicate that of all these pathways, the air-grass-cow-milk pathway is by far the dominant and controlling dose factor. This occurs because: The dose factors for the radioiodines are much greater than dose factors for any of the other radionuclides ~ The radioiodines contribute essentially all of dose by this pathway with I-131 typically contributing greater than 95%. Since the air-grass-cow-milk pathway is the controlling pathway and radioiodine the controlling activity, the critical organ is the thyroid. To produce the most conservative result, doses are determined using effective dose transfer factors for radioiodine via the air-grass-cow-milk pathway and the infant thyroid as the receptor. An additional degree of conservatism is provided by totalling the cumulative release of all radioiodines and articulates with the radioiodine effective dose transfer factor to estimate infant thyroid dose. Doses due to iodines and particulates are determined with the following equation:

3. 17x10, D'TG '~ g DMk =

TG))) = 6.5 x 10 mrem r pCi/m . sec Qa the quantity of radionuclide I-133) released in a given effluent i (I-131 and stream based on a single analysis k, (pCi) Equation 22 is adapted from radioiodine dose equations in Regulatory Guide 1.109. . The conservatism factor, 0.8, is derived from historical radionuclide distributions observed in gas samples. The relative deposition rate onto ground D/Q is derived from Turkey Point historical meteorological data collected during calendar years 1976 and 1977 and atmospheric models from Regulatory Guide 1.111. The effective dose transfer factor for the air-grass-cow-milk-infant-thyroid pathway, TG,z, is based on historical data collected in 1978, 1979, and 1980. The technical basis for TG>z> is given in the ODCM Appendix B. The quantity of radionuclide i released in a given effluent stream (Q,-z) is determined using ODCM equation 20. The specifications for determining dose via the air-grass-cow-milk pathway given in NUREG-0133 states that the cow should be within 5 miles of the release point. At Turkey Point, there are no milk cows within 5 miles of the- plant release point. Under these circumstances, NUREG-0133 states that a cow may be assumed between 4.5-5.0 miles in the worst sector. For the Turkey Point plant, the worst sector is the populated area due west of the plant. As a result, dose due to iodine, tritium, and particulates is determined for a phantom cow on pasture 4.5 miles west of the plant where the 34 01/01/94 0 relative'~m deposition rate onto the ground D/Q is

5. Oxl0 ~.

5.1.3.3 Alternate Methods of Determining Dose Due to Airborne Iodines, Tritium and Particulates In addition to determining dose due to the dominant air-grass-cow-milk pathway, the ODCM provides equations for evaluating dose via other pathways. These equations are based on examples described in Regulatory Guide 1.109 and NUREG-0133. Equations are provided to evaluate the following dose pathways: Inhalation and irradiation dose due to airborne concentrations of radioactive material other than noble gas. ODCM equation 23. Deposition from the atmosphere onto vegetation or the ground. ODCM equation

24. Deposition is from airborne concentrations of radioactive material other than noble gas.

Dose from airborne tritium via vegetation, air-grass-cow-milk or air-grass-cow-meat. ODCM equation 25. ~ Cumulative dose via a given pathway as a result of measured discharges from a release point. ODCM equation 26. These alternate equations may be used to satisfy the requirements of Technical Specification 3.11.2.3. Except for the cumulative dose equation (26)-, all of the dose equations share a common format as illustrated by equation 23: D~ = 3.17~0 ' 'g~~ ' TA~(p (23) P 35 01/01/94 0 where: Dank the dose commitment to organ n of a person in age group a due to radionuclides identified in analysis k of an air effluent, (mrem) 3.17 x 10 conversion constant, (yr/sec) xd/Q atmospheric dispersion factor adjusted .for depletion by deposition, (sec/m~) Q,.k = the quantity of radionuclide in a given effluent stream based on i released analysis k, (pCi) All of the equations are used to determine a dose (D) to an organ (n) of a person in a particular age group (a) identified in an analysis (k) of an effluent air sample. Although no specific age group (a) or organ (n) is identified in the equation, the most restrictive case is the infant for any organ. As a result the infant will be selected for purposes of making conservative dose estimates. All of the equations use an atmospheric dispersion 'factor (X/Q, Xd/Q.or D/Q). These factors have been determined using historical Turkey Point meteorological data and models from Regulatory Guide 1.111. The factors for sixteen compass sectors around the Turkey Point plant are given in the ODCM Tables 3-6 (X/Q), 3-7 (Xd/Q) and 3-8 (D/Q) . Each of the pathways uses a unique location to evaluate dose to' person, these are: The inhalation and irradiation and tritium pathways evaluate dose at the nearest garden (with residence assumed) which is 3.6 miles west of the plant where the f /Q factor (for inhalation and irradiation is 1 x 10 sec/mr and the f/Q factor (tritium) is also 1 x 10 sec/m~. The deposition from the atmosphere onto vegetation or the ground pathway evaluates dose at the phantom cow location 4.5 miles west of the plant where the D/Q value is 5.0 x 10 m 36 01/01/94 To determine conformance with Technical Specification 3.11.2.3, a cumulative dose calculation is made using the following equation: (26) where: D, = .the dose commitment to organ n of a person in age group (a) k = the counting either: index; it may represent p, analysis of a grab sample w, a weekly sample analysis m, a monthly composite analysis, or q, a quarterly composite analysis 5.1.4 Projected Dose Technical Specification 3.11.2.4 requires that the ventilation exhaust treatment system and gas decay tank system shall be operable and appropriate portions of these systems shall be used to reduce releases of radioactivity when the ro'ected doses in 31 da s due to gaseous effluent releases, From each unit, to areas at and beyond the site boundary would exceed: 0.2 mrad to air from gamma radiation or 0.4 mrad to air from beta radiation or 0.3 mrad to any organ of a Member of the Public Technical Specification 4.11.2.4 further states that doses from each unit to areas at and beyond the site boundary shall be projected at least once per 31 days in accordance with the methodology and parameters in the ODCM when Gaseous Radwaste Treatment Systems are not being fully utilized. At Turkey Point, these Technical Specifications requirements are satisfied with ODCM equation 29 as follows: 37 01/01/94 31 'D (30) X where: the projected dose during the month, (mrem) 31 number of days in a calendar month, (days) number of days in current month to date represented by available radioactive effluent sample, (days) I D dose to date during current month calculated according to ODCM dose equations Alternately, the monthly dose may be projected by computing the dose accumulated during the most recent month and assuming the result represents the projected dose for the current month. This equation, adapted from dose projection equations in Regulatory Guide 1.109 and NUREG-0133, extrapolates the dose to date in a current month to include the entire month. It should be noted that equation 30 is the same as ODCM equation 8 for liquids. 5.1.5 Effluent Noble Gas Monitor Setpoints Technical Specification 3.3.3.6 requires that radioactive gaseous effluent monitoring instrumentation channels be ~o arable with their alarm/trip setpoints set to ensure that the limits of specification 3.11.2.1 and 3.11.2.5 are not exceeded. The alarm/trip setpoints of the channels meeting specification 3.11.2.1 shall be determined and adjusted in accordance with methodology and parameters in the ODCM. The requirements of this Technical Specification can be met using the following equation: S= 1.06 h 'S~ + Bkg (27) F Xlg] P Cg 'DFg 38 01/01/94 where: S = The alarm setpoint, (cpm) 1 '6 conversion constant; 500 mrem/yr

The allowable operating setpoints will be controlled administratively by assigning a fraction of the total allowable release to each of the release sources. Equation 27 is based on setpoint methodology described in NUREG-0133. This equation uses known factors about the gas monitor, atmospheric dispersion, and radionuclide distribution and background radiation to determine a setpoint. The required equation factors are: The monitor An efficiency factor, h, must be known. Gas flow past the monitor must be known. Zt should be noted that this is not the flow of the vent or stack through which gas is being discharged. 39 01/01/94 Atmospheric dispersion (g/Q) The g/Q values for Turkey Point are based on historical meteorological data and methodology from Regulatory Guide 1.111. Turkey Point y/Q data are given in ODCM Table 3-6. The air dose conversion factor DF< is a factor which converts the ground level release of radionuclide i to the total ,body dose equivalent at the location of potential exposure. DF< factors for Turkey Point are taken from Regulatory Guide 1.109 Table B-1 and are given in ODCM Table 3-5. Radionuclide distribution There are three acceptable means to determine radionuclide distribution, these are: To perform a gamma spectrum analysis of the gas release.. Results of one or more analysis may be averaged to obtain a representative spectrum. This is the preferred way of determining release concentrations. From the historical spectrum of noble gas distributions given in ODCM Table 3-2. This table is used in conjunction with a noble gas gross activity analysis. By attributing the total or gross activity to Xe-133. This technique is valid because Xe-133 comprises about 994 of the noble gas activity. Background (Bkg) The radioactive background in which the monitor operates should be known and added to the setpoint value to prevent setting the monitor setpoint too low. The set point is determined by evaluating the location at the site boundary where minimum atmospheric dispersion occurs. This location is 1950 meters SSE of the plant where the g/Q value is 5.8 x 10 " sec/m . 40 01/01/94 The limiting factor when using equation 27 to determine a setpoint is the total body dose rate limit of 500 mrem/yr which is included in the 1.06 conversion factor. The use of total body dose assumes that the total body dose will be the controlling dose rate and the dominant contributor to this dose will be Xe-133. The requirements of Technical Specification 3.3.3.6 can also be met by using the following equation: EC'h 'S~ 4.7x20 4 ' '/g (as) where: EC = the unrestricted area effluent concentration for the effluent noble gas mixture 4.7 x 10 conversion constant, 1m~ x 1 min 35.37ft 60 sec h = monitor response to activity concentration of effluent, f ~c m pci/cm ) 'F = flow of gaseous effluent stream, i.e., flow past the monitor (ft~/min) atmospheric dispersion factor at the offsite location of interest, (sec/m~) Sf A factor to allow for multiple sources from different or common release points. The allowable operating setpoints will be controlled administratively by assigning a fraction of the total allowable release to each of the release sources. The unrestricted area effluent concentration (EC) for the noble gases is determined from the distribution of noble gases in the release as follows: Cg EC= Cg + (2s) EC~ where: 41 01/01/94 C< = concentration of radionuclide effluent i in a gaseous ECi 10 times the unrestricted area effluent concentration for radionuclide i. Values of EC< for the noble gases are given in 10CFR20, Appendix B, Table 2, Column 1. The differences between equation 27 and equation 28 are: The dose rate in equation 27 represented hy the term has been replaced by effluent concentration values based on noble gas release concentration as represented by the term EC which is derived using equation 28 and EC,. values for the noble gases from 10CFR20 Appendix B, Table 2, Column 1. As a result of this replacement, the air dose conversion constant DF,. is not required in equation 28. The background term included in equation 27 is not required in equation 28 because background is an inherent part of EC. The limiting factor of 500 mrem/yr total body dose in equation 27 has been replaced by EC. As a result the conversion factor changes in equation 28. The atmospheric dispersion factor X/Q for both equation 27 and equation 28 are the same. Setpoints using EC are also evaluated at the point of minimum atmospheric dispersion which is 1950 meters SSE of the plant where the X/Q value is 5.8x10 ~ sec/m~. 01/01/94 6.0 Annual Dose Commitments Technical Specification 3.11.4 requires that the annual (calendar year) dose or dose commitment to any Member of the Public due to releases of radioactivity and radiation from uranium fuel cycle sources shall be limited to: 6 25 mrems whole body or any organ except the thyroid < 75 mrems to the thyroid The requirements of Technical Specification 3.11.4 can be satisfied by applying the following equations from the ODCM.

For determinations of annual dose, the y/Q value is for the most exposed receptor not the minimum dispersion point at the site boundary. For Turkey Point the most exposed receptor is located 3.6 miles west northwest of the plant at the location of the nearest garden. The g/Q value at that location is 1.0x10 ~ sec/m~.
