ODCM Revision 0014 Page 53 of 208 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.1 LIQUID EFFLUENTS 1/2.2.1.1 CONCENTRATION This requirement is provided to ensure that the concentration of radioactive materials released at any time in liquid waste effluents from the site to UNRESTRICTED AREAS will be less than or equal to ten times the concentration levels specified in 10 CFR Part 20, Appendix B, Table 2, Column 2.

This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will result in exposures within (1) the Section II.A limits of Appendix I to 10 CFR Part 50, and (2) the limits of 10 CFR Part 20.1301 (a) (1) to a member of the public. The concentration limit for noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its Maximum Permissible Concentration in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission of Radiological Protection (ICRP) Publication 2.

1/2.2.1.2 DOSE This requirement is provided to implement the dose requirements of Section II.A, III.A, and IV.A of Appendix I, 10 CFR Part 50. The requirement implements the guides set forth in Section II.A of Appendix I. Compliance with this control will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR Part 20.1301 (a) (1) per 56FR23374.

This action provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonable achievable". Also, for fresh water sites with drinking water supplies which can potentially be affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR 141. The dose calculations in Section 6.0 implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in Section 6.0 for calculating the doses due to the actual release rates of radioactive materials in liquid effluents will be consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Implementing Appendix I," October 1977 and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I" April 1977. NUREG-0133 provides methods for dose calculations consistent with Regulatory Guides 1.109 and 1.113.

ODCM Revision 0014 Page 54 of 208 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.1 LIQUID EFFLUENTS 1/2.2.1.3 LIQUID WASTE TREATMENT This section requires that the appropriate portions of the liquid radwaste treatment system be used when specified. This provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable." This requirement implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and design objective Section II.D of Appendix I to 10 CFR 50. The specified limits governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the guide set forth in Section II.A of Appendix I, 10 CFR 50, for liquid effluents.

This section also requires submittal of a special report if the limiting values are exceeded and unexpected failures of non-redundant radwaste processing equipment halt waste treatment.

1/2.2.2 GASEOUS EFFLUENTS 1/2.2.2.1 DOSE RATE This requirement is provided to ensure that the external dose rate at anytime at the SITE BOUNDARY from gaseous effluents from all units on the site will be within the limits of 10 CFR Part 20.1301 (a) (2) for UNRESTRICTED AREAS. The 500 mrem/yr dose rate will ensure that the instanteous dose rate is well below 2 mrem/hr. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, to annual average concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates to an individual at or beyond the SITE BOUNDARY to

< 500 mrem/year to the total body or < 3000 mrem/year to the skin. These release rates also restrict, at all times, the corresponding thyroid dose rate above background to an infant via the cow-milk-infant pathway to < 1500 mrem/year for the nearest cow to the plant.

The action for this requirement requires that appropriate corrective action(s) be taken to reduce gaseous effluent releases if the limits are exceeded.

ODCM Revision 0014 Page 55 of 208 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.2 GASEOUS EFFLUENTS 1/2.2.2.2 DOSE - NOBLE GASES This requirement is provided to implement the requirements of Section II.B, III.A, and IV.A of Appendix I, 10 CFR Part 50. The limits are the guides set forth in Section II.C of Appendix I.

Compliance with this control will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301 (a) (1) per 56FR23374.

The action to be taken for exceeding these limits provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents will be kept "as low as reasonably achievable." Section 7.0 calculational methods implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. Section 7.0 calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodologies provided in NUREG/CR-1004, "A Statistical Analysis of Selected Parameters for Predicting Food Chain Transport and Internal Dose of Radionuclides."

October 1979 and Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purposes of Evaluating Compliance with 10 CFR Part 50, "Appendix I," Revision 1, October 1977 and 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.

These ODCM equations also provide for determining the air doses at the exclusion area boundary are based upon the historical average atmospheric conditions. NUREG-0133 provides methods for dose calculations consistent with Regulatory Guides 1.109 and 1.111.

If these limits are exceeded, this section requires that a special report be prepared and submitted to explain violations of the limiting doses contained in the section above.

ODCM Revision 0014 Page 56 of 208 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.2 GASEOUS EFFLUENTS 1/2.2.2.3 DOSE 131, 1-133, TRITIUM AND RADIONUCLIDES IN PARTICULATE FORM WITH HALF-LIVES GREATER THAN EIGHT DAYS This requirement is provided to implement the requirements of Section II.C, III.A, and IV of Appendix I, 10 CFR Part 50. The limits are the guides set forth in Section II.C of Appendix I. Compliance with this control will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301 (a) (1) per 56FR23374.

The action to be taken for exceeding these limits provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents will be kept "as low as reasonably achievable." Section 7.0 calculational methods implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated.

Section 7.0 calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodologies provided in NUREG/CR-1004, "A Statistical Analysis of Selected Parameters for Predicting Food Chain Transport and Internal Dose of Radionuclides," October 1979 and Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purposes of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and 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. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions.

The release rate specifications for iodines, radioactive material in particulate form and radionuclides other than noble gases are dependent on the existing radionuclide pathways to man in the UNRESTRICTED AREA.

The pathways which were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides,

2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

If these limits are exceeded, this section requires that a special report be prepared and submitted to explain violations of the limiting doses contained in the section above.

ODCM Revision 0014 Page 57 of 208 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.2 GASEOUS EFFLUENTS 1/2.2.2.4 GASEOUS RADWASTE TREATMENT This requires that the offgas charcoal adsorber beds be used when specified to treat gaseous effluents prior their release to the environment. This provides reasonable assurance that the release of radioactive materials in gaseous effluents will be kept "as low as is reasonable achievable". This requirement implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and design objective Section II.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the guide set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

This action requires that a special report be prepared and submitted to explain reasons for any failure to comply with the above requirements.

1/2.2.3 TOTAL DOSE This requirement is provided to meet the dose limitations of 40 CFR 190.

Compliance with this control will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301 (a) (1) per 56FR23374. This requirement requires the preparation and submittal of a Special Report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 190 if the individual reactors remain within the reporting requirement level. The Special Report will describe a course of action which should result in the limitation of dose to a MEMBER OF THE PUBLIC for the calendar year to be within 40 CFR 190 limits.

For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities within a radius of five miles must be considered.

1/2.3 RADIOLOGICAL ENVIRONMENTAL MONITORING 1/2.3.1 MONITORING PROGRAM The REMP required by this section provides measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides, which lead to the highest potential radiation exposures of individuals resulting from the station operation. This monitoring program thereby supplements the

ODCM Revision 0014 Page 58 of 208 BASES 1/2.3 RADIOLOGICAL ENVIRONMENTAL MONITORING 1/2.3.1 MONITORING PROGRAM (continued) radiological effluent monitoring program by verifying that the measurable concentration of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. The REMP satisfies the requirements of 10 CFR 50, Appendix A, Criteria 64 and 10 CFR 50, Appendix I, Section IV.B.2.

1/2.3.2 LAND USE CENSUS This requirement is provided to ensure that changes in the use of UNRESTRICTED AREAS are identified and that modifications to the monitoring program are made if required by the results of this census.

The best survey information from the door-to-door, mail, telephone, aerial or consulting with local authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via the leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetation assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage)., and 2) a vegetation yield of 2 kg/square meter.

1/2.3.3 INTERLABORATORY COMPARISON PROGRAM The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive materials in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

ODCM Revision 0014 Page 70 of 208 SECTION 6.0 LIQUID EFFLUENTS

ODCM Revision 0014 Page 71 of 208 6.0 - LIQUID EFFLUENTS RELEASE POINTS The minimum flow available for dilution of radwaste are shown below:

---

• open - 2 pumps @ 200,000 gpm/pump -----

Radwaste --... > ---- > Discharge T Conduit

--- + closed - 50,000 gpm or helper

ODCM Revision 0014 Page 72 of 208 6.1 LIQUID RELEASES 6.1.1 Pre-release Analysis/ECL - Sum of the Ratios Prior to a batch release, a grab sample will be analyzed to determine the concentration (Ci) of each gamma emitting radionuclide i in the radwaste tank. The following equation is used to calculate effluent concentration limit (ECL) fractions (Mi).

Ci Mi = (6.1)

ECLi where:

Mi = ECL fraction of radionuclide i.

Ci = concentration of radionuclide i in the radwaste tank, pCi/ml.

ECLi = ECL of radionuclide i as specified in Control 1.2.1.1, pCi/ml.

The sum of the ratios (R) will be calculated by the following relationship:

R = Z Mi (6.2) i where:

R = the sum of the ratios.

Mi = ECL fraction from equation 6.1.

6.1.2 Release Flow Rate Calculations The sum of the ratios at the diffuser pipes must be

• 10 due to a liquid release. The following relationship will assure this criterion is met:

R[f/(f+F)]

• 10 (6.3) where:

f = the effluent flow rate (gallons/minute) before dilution.

R = the sum of the ratios as determined by Equation 6.2.

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 ECL limit is not exceeded.

ODCM Revision 0014 Page 73 of 208 6.1.3 Post-release Analysis A post-release analysis will be done using actual release data to ensure that the limits specified in Control 1.2.1.1 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 6.1, 6.2 and 6.3 to demonstrate compliance with the limits in Control 1.2.1.1. This data and setpoints will be recorded in auditable records by plant personnel.

ODCM Revision 0014 Page 74 of 208 6.2 INSTRUMENT SETPOINTS Alarm/trip setpoints for each liquid monitor will be established and set such that Equation 6.3 is satisfied. The locations and identification numbers for each liquid effluent radiation detector are shown in Figures 6.1 and 6.2. This section of the ODCM describes the methodology that will be used to determine allowable values. The allowable values are then used to determine the physical settings on the monitors. The physical settings are calculated in the applicable Scaling and Setpoint Document.

6.2.1 Release Point Monitor Allowable Values There is only one point through which routine releases are made from BFN, the Liquid Radwaste System. All releases from the Liquid Radwaste System are in a batch mode, and the monitor is looking at an undiluted waste stream as it comes out of a tank. The purpose of the monitor setpoint for these batch releases is to identify any release that would have the potential to exceed ten times the 10 CFR 20 limits after dilution.

Allowable values used to determine the setpoints are calculated as described here.

For each release, a setpoint is calculated based on the monitor response to the activity in the release stream if the release were large enough to exceed ten times the 10 CFR 20 limits after dilution. This maximum calculated setpoint, Smax, is calculated using Equation 6.4 below. A comparison is made between this calculated setpoint and the default setpoint (see Section 6.2.2) to determine which is used. The actual monitor setpoint for the release is set equal to the default setpoint, or to the maximum calculated setpoint, whichever is less.

Calculated Maximum Monitor Setpoint i0" SF (Fw + (FD

• Fdil))

Smax = (ER - B) + B (6.4)

Fw R where:

SF = safety factor for the monitor.

Fw = flow of waste stream, gpm.

Fdil = flow of the dilution stream, gpm.

FD = fraction of dilution flow allocated to this release point. For BFN this fraction is equal to one.

B = background, cpm.

R = sum of the ratios for the release point as calculated in Section 6.1.1.

ER = expected monitor response, cpm,

= B + F Ei

• Ci (6.5) i where:

B = monitor background, cpm.

Ei = monitor efficiency for nuclide i, cpm per pCi/cc.

Ci = tank concentration of nuclide i, pCi/cc.

ODCM Revision 0014 Page 75 of 208 6.2.2 Default Allowable Values 6.2.2.1 Radwaste Discharge Monitor The default allowable value for the radwaste discharge monitor (RM-90-130), shown in Figures 6.1 and 6.2, will be established using the methodology below. The alarm/trip allowable value will be set such that Equation 6.3 is satisfied. The default trip allowable value for the monitor, which will automatically isolate the release, is set at less than or equal to the limit in Control 1.2.1.1. The alarm allowable value is set at 90% or less of the trip allowable value.

The default maximum activity concentration1 of liquid radwaste that can be discharged can be calculated as:

A F + f f

• E WFi i

ECL.

where:

A = default maximum batch activity concentration, pCi/ml.

ECLi = ECL of radionuclide i as specified in Control 1.2.1.1, pCi/ml.

WFi = weighting factor for nuclide i, defined as the fraction of the total concentration which is attributed to nuclide i.

F = dilution water flow rate, gpm.

f = maximum discharge flow rate, gpm.

1 The default maximum activity concentration is based on a selected isotopic mixture so that an allowable value can be calculated. The selected isotopic mixture will be documented in 0-TI-45. If ten times the actual batch ECL fraction is less restrictive than ten times the ECL fraction for the selected isotopic mixture, then the actual activity concentration may be higher than the calculated maximum activity concentration; this is the case for which the maximum allowable value defined in Section 6.2.1 would be indicated.

ODCM Revision 0014 Page 76 of 208 The default monitor isolation allowable value, in cps, for releases is calculated using the following equation:

6.2.2.2 Raw Cooling Water and Residual Heat Removal Service Water Monitors The allowable value for the Raw Cooling Water (RCW) monitors and the Residual Heat Removal Service Water (RHRSW) monitors (RM-90-132 and RM-90-133,134 respectively), shown in Figure 6.1, will be established using the methodology below. The alarm/trip allowable values will be set such that Equation 6.3 is satisfied. The allowable values for these monitors, which will alarm in the control room, are based on ten times the 10 CFR 20 Appendix B concentration limits. These allowable values are also based on a selected isotopic mixture.

The monitor alarm allowable values, in cpm, for the RCW and RHRSW effluent monitors are calculated using the following equation:

Monitor Allowable Values * (A

where:

A = total activity concentration, pCi/ml.

ODCM Revision 0014 Page 77 of 208 6.3 CUMULATIVE LIQUID EFFLUENT DOSE CALCULATION Doses due to liquid effluents are calculated for each release for all age groups (adult, teen, child and infant) and organs (bone, liver, total body, thyroid, skin, kidney, lung and GI tract). Pathways considered are drinking water ingestion, fish consumption and shoreline recreation. The maximum individual dose from drinking water is assumed to be that calculated at the location immediately downstream from the diffuser. The maximum individual dose from fish ingestion is assumed to be that calculated for the consumption of fish caught anywhere between the plant and the first downstream dam (Wheeler Dam). The maximum potential recreation dose is calculated for a location immediately downstream of the plant outfall. Dose factors for these age groups and pathways are calculated as described in Section 6.7. For pathways with no age or organ specific dose factors (i.e., shoreline recreation), the total body dose will be added to the internal organ dose for all age groups.

6.3.1 Dose Calculation The general equation for the dose calculation for each organ j is:

Dj = Aij T Ci D (6.6) i where:

Aij = the total dose factor to the total body or any organ j for nuclide i, mrem/h per pCi/ml. The total dose factor is the sum of the dose factors for water ingestion, fish ingestion, and shoreline recreation, as defined in Section 6.7.

T = the length of time period over which the concentrations and the flows are averaged for the liquid release, h.

Ci = the average concentration of radionuclide i, in undiluted liquid effluent during the time period T from any liquid release, pCi/ml.

D = the near field average dilution factor for Ci during any effluent release.

= FLOWw 0.30 RF where:

FLOWw = maximum undiluted liquid waste flow during the release, cfs.

0.30 = mixing factor of effluent in river, defined as the percentage of the riverflow which is available for dilution of the release.

RF = default riverflow, cfs. For each release, this value is set to 44,000 cfs (the average monthly riverflow for the period of 1986-1992).

From the four age groups considered, the maximum is determined by comparing all organ doses for all age groups. The age group with the highest single organ dose is selected as the critical age group.

ODCM Revision 0014 Page 78 of 208 6.3.2 Cumulative Doses Quarterly and annual sums of all doses are determined for each release to compare to the limits given in ODCM Control 1.2.1.2. These quarterly and annual sums will be the sum of all the doses for each release in the quarter or year respectively.

6.3.3 Comparison to Limits The cumulative calendar quarter and calendar year doses are compared to the limits in ODCM Control 1.2.1.2 prior to and after each liquid release.

ODCM Revision 0014 Page 79 of 208 6.4 LIQUID RADWASTE TREATMENT SYSTEM The Liquid Radwaste Treatment System (LRTS) shall be maintained and operated to keep releases ALARA. A flow diagram for the LRTS is given in Figure 6.2.

ODCM Revision 0014 Page 80 of 208 6.5 DOSE PROJECTIONS Dose projections 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.

ODCM Revision 0014 Page 81 of 208 6.6 DOSE CALCULATIONS FOR REPORTING PURPOSES A complete dose analysis utilizing the total estimated liquid releases for each calendar quarter will be performed and reported as required in ODCM Administrative Control 5.2. Methodology for this analysis is that which is described in this section using the quarterly release values reported by the plant personnel.

ODCM Revision 0014 Page 106 of 208 SECTION 7.0 GASEOUS EFFLUENTS

ODCM Revision 0014 Page 107 of 208 7.0 GASEOUS EFFLUENTS RELEASE POINTS DESCRIPTION There are eleven monitored discharge points at BFN: a Reactor Building Exhaust for each unit, the Radwaste Building Exhaust, two sets of Turbine Deck Roof Fans for each unit, and the Stack. The Reactor and Radwaste Exhausts are located on the roof of the reactor building.

The Reactor Building Exhausts include exhaust from the refuel floor of the reactor buildings, exhaust from the Primary Containment Purge System, and exhaust from the turbine buildings. These discharge points are monitored by radiation monitors 1-,2-,3-RM-90-250.

The Radwaste Building Exhaust includes exhaust from the common radwaste building. This discharge point is monitored by radiation monitor RM-90-252.

There are nine roof fans on the roof of each unit's turbine building to provide building ventilation. These are generally used in the warmer months to control building temperature. For each unit, there are two radiation monitors. One of these monitors the exhaust through four of the fans (1-,2-RM-90-249 and 3-RM-90-251). The other monitors the exhaust through the remaining five fans (I-,2-RM-90-251 and 3-RM-90-249).

The common 600 foot plant stack receives the Condenser Offgas exhaust, the Filter Cubicle exhaust, the Steam Packing and Mechanical Vacuum exhaust, and the Standby Gas Treatment System (SBGTS) exhaust. The stack effluents are monitored by radiation monitors RM-90-147 and 148.

Figures 7.1 and 7.2 show the Offgas System, the Standby Gas Treatment System and normal building ventilation with effluent monitor locations.

ODCM Revision 0014 Page 108 of 208 7.1 GASEOUS EFFLUENT MONITOR INSTRUMENT SETPOINTS ODCM Control 1.1.2 requires that gaseous effluent monitors have alarm/trip setpoints to ensure that ODCM dose rate limits are not exceeded. This section of the ODCM describes the methodology that is used to determine the allowable values which are used to calculate the physical settings on the monitors. The monitor setpoints are calculated in the applicable Scaling and Setpoint Document. Figures 7.1 and 7.2 show the Offgas System, the Standby Gas Treatment System and normal building ventilation with the effluent monitor locations.

All gaseous releases from BFN are continuous, so allowable values are calculated for each of the monitors as a part of a release permit package per sampling requirements of Table 2.2-2. Using the actual radionuclide mix as measured in a sample, a maximum allowable value is calculated (as described below) and compared to a default allowable value assigned to that monitor.

The default allowable values are described in Section 7.1.2. The lower of the two values is the recommended setpoint for that release point. If the release point is one of several leading into a common discharge point, all current releases into that discharge point are used in the calculation of the discharge point monitor allowable value (e.g., the stack).

7.1.1 Maximum Allowable Value An expected monitor response is calculated from the sample results:

R = B + Z Ei Ci (7.1) i where:

B = monitor background, cpm or cps.

Ei = efficiency factor for the monitor for nuclide i, cpm per pCi/cc or cps per pCi/cc.

Ci = measured concentration of nuclide i, pCi/cc.

The expected response is then used to determine the calculated maximum allowable value, Smax in cpm or cps. This value corresponds to the dose rate limit for the measured radionuclide mix and is determined using the following equation:

DRlim Smax = ( A SF ( (R - B))) + B (7.2)

DR where:

A dose rate allocation factor for the release/discharge point, dimensionless. The dose rate allocation factor for the stack is 0.1, the building vent allocation factors are equal to 0.9 times the fraction of the total building flow assigned to that particular vent.

ODCM Revision 0014 Page 109 of 208 SF = safety factor for the monitor, dimensionless.

DRlim = the dose rate limit, mrem/y.

= 500 mrem/y to the total body for noble gases,

= 3000 mrem/y to the skin for noble gases, and DR = the calculated dose rate for the release, mrem/y.

= DRTB for total body (as described in Section 7.3.2.1),

= DRs for skin (as described in Section 7.3.2.2), and R = expected monitor response (as calculated above) cpm or cps.

B = the monitor background, cpm or cps.

7.1.2 Default Allowable Values The methodology for determining the default alarm/trip allowable values is divided into two major parts. The first consists of backcalculating from a dose rate to a release rate limit, in pCi/s, for each release point. The methodology for determining these release rate limits is given in Section 7.2. The second part consists of using the release rate limits to determine default allowable values for the monitors.

The default allowable values are calculated using the following equation.

Allowable Value

• r f A + B (7.3)

FE where:

r = release rate limit for stack or ground level, pCi/s. The release rate limits used for the allowable value calculation are 1.44E+07 pCi/s for the stack and 1.50E+05 pCi/s for the building vents.

f = fraction of the limits r which is allowed for the release mode (elevated or ground level).

NOTE: The sum of the f values for elevated and ground levels must be less than or equal to 1. This lowers the limits to ensure that the site dose rate limit will not be exceeded if both the stack and the ground level release rate limits were reached simultaneously.

A = allocation factor. This is the portion of the release rate limit r which is assigned to the release point under consideration. This ensures that the ground level release rate limit will not be exceeded if all building vents were to reach their limit simultaneously. This is equal to 1 for the stack. The building vent release rate limit is divided among the ten vents based on the flow rates.

F = flow rate for the vent, cc/s. Maximum flow rates are used to ensure conservative setpoints.

E = efficiency of the monitor, (pCi/cc)/cpm or (pCi/cc)/cps.

B = background of the monitor, cpm or cps.

The calculation of these setpoints are documented further in 0-TI-15 and the applicable Scaling and Setpoint Document, including the numerical values for each of the parameters described above.

ODCM Revision 0014 Page 110 of 208 7.2 RELEASE RATE LIMIT METHODOLOGY A dose rate (DTB, DS or DTH) is calculated based on the design objective source term mix used in the licensing of the plant. Dose rates are determined for (1) noble gases as described in Section 7.3.2 and (2) iodines and particulates as described in Section 7.3.3.

The dose rate limits of interest are:

Total Body = 500 mrem/y Skin = 3000 mrem/y Maximum Organ = 1500 mrem/y A release rate limit based on organ dose rates is not considered since iodine and particulate releases are not determined on a real time basis. The total body and skin dose rate limits are divided by the corresponding calculated dose rates described above:

Total Body Dose Rate Limit RTB(vent or stack) =

DTB (vent or stack)

Skin Dose Rate Limit Rs(vent or stack) =

DS (vent or stack)

These ratios represent how far above or below the guidelines the dose rate calculations were.

A total release rate, Q, for each release level (building vent or stack) is calculated, using the source term data in Table 7.2. Thus, two total release rates are calculated:

Qngv = Total noble gas release rate from building exhaust vents, Ci/s.

Qngs = Total noble gas release rate from main stack, Ci/s.

To obtain a release rate limit, r, for each release level, the total release rate, Q, for that release level is multiplied by the corresponding ratio, R:

For noble gases released from building vents:

rngv = RTBv Qngv, or

= RSv Qngv whichever is more restrictive, i.e., smaller.

ODCM Revision 0014 Page 111 of 208 where:

rngv = Calculated release rate limit for noble gases released from building vents.

RTBv = Ratio of total body dose rate limit to total body dose rate for building vent releases, as calculated above.

Qngv = Total Table 7.2 noble gas release rate from building vents.

RSv = Ratio of skin dose rate limit to skin dose rate for building vent releases, as calculated above.

For noble gases released from the stack:

rngs = RTBs Qngs, or

= RSs Qngs whichever is more restrictive, i.e., smaller.

where:

rngs = Calculated release rate limit for noble gases released from the stack.

RTBs = Ratio of total body dose rate limit to total body dose rate for stack releases, as calculated above.

Qngs = Total Table 7.2 noble gas release rate from stack.

RSs = Ratio of skin dose rate limit to skin dose rate for stack releases, as calculated above.

The release rate limits, r, calculated for BFN using this methodology are:

Noble Gas Stack rngs = 1.44E+01 Ci/s Building Vents rngv = 1.50E-01 Ci/s

ODCM Revision 0014 Page 112 of 208 7.3 GASEOUS EFFLUENTS - DOSE RATES 7.3.1 RELEASE SAMPLING As required by Table 2.2-2, a grab sample is taken and analyzed to determine the concentration, pCi/cc, of each noble gas nuclide. On at least a weekly basis, filters are analyzed to determine the amount of iodines and particulates released. Composite samples are maintained (as required by Table 2.2-2) to determine the concentration of certain nuclides (e.g., Sr-89, Sr-90, and alpha emitters).

7.3.2 NOBLE GAS DOSE RATES Dose rates are calculated in order to determine compliance with the requirements of ODCM Control 1.2.2.1. Dose rates are calculated for total body and skin due to noble gases using semi-infinite and finite cloud models as described in NUREG 0133. The release mode will determine the model used:

turbine building releases are treated as ground level and use the semi-infinite model; reactor and radwaste building vents are treated as split-level (or mixed mode) and use the semi-infinite model; and stack releases are elevated and use the finite cloud model.

7.3.2.1 Total Body Dose Rate The dose rate to the total body, DRTB in mrem/y, is calculated using the following equation:

DRTB = [Vi Qis + DFBi ((%/Q)g Qig) + DFBi ((%/Q)m Qim)] (7.4) i where:

Vi = the constant for each identified noble gas radionuclide accounting for the gamma radiation from the elevated finite plume, in mrem/y per pCi/s, as given in Table 7.4 Qis = the release rate of radionuclide i, in gaseous effluents from the stack, pCi/s.

DFyi = the air dose factor due to gamma emissions for each identified 3

noble gas radionuclide, mrad/y per pCi/m (unit conversion factor of 1.1 mrem/mrad converts air dose to skin dose) (Table 7.4).

X/Qg = for ground level releases, the highest calculated annual average relative concentration for any area at or beyond the unrestricted area boundary, s/m 3 (Table 7.1).

Qig = the release rate of radionuclide i, in gaseous effluents from all ground level releases, pCi/s.

Qim = the release rate of radionuclide i, in gaseous effluents from all split level releases, pCi/s.

ODCM Revision 0014 Page 114 of 208 7.3.3 1-131, 1-133, TRITIUM AND ALL RADIONUCLIDES IN PARTICULATE FORM WITH HALF-LIVES OF GREATER THAN 8 DAYS - ORGAN DOSE RATE Organ dose rates due to 1-131, 1-133, Tritium and all radionuclides in particulate form with half-lives of greater than 8 days, DRj in mrem/y, are calculated for all age groups (adult, teen, child, and infant) and all organs (bone, liver, total body, thyroid, kidney, lung, and GI Tract) using the following equation:

DRj = Z FD [ CTD(X/Q)D[RIT+RCTP] + I CiD[(X/Q)DRIi+(D/Q)D[RCPi+RGil]] (7.6)

The organ dose rates for all pathways are summed to find the total site dose rate. The maximum organ dose rate is selected from among the dose rates calculated for all locations, organs, and age groups.

ODCM Revision 0014 Page 115 of 208 7.4 CUMULATIVE DOSE - NOBLE GASES Doses to be calculated are gamma and beta air doses due to exposure to noble gases. For elevated releases (stack), a finite cloud model will be used for the gamma dose. All other releases will be calculated using a semi-infinite cloud model. The doses will be calculated at three locations: the land-site boundary locations with the highest annual-average split-level X/Q; the land-site boundary location with the highest ground-level annual-average X/Q; and the offsite location with the highest annual-average elevated-level x/Q.

The joint frequency distributions for the three levels of met data are given in Table 7.3. The locations, and their respective dispersion factors are listed in Table 7.1. Dispersion factors are calculated using the methodology described in Section 7.9.2 No credit is taken for radioactive decay.

7.4.1 Gamma Dose to Air The gamma air dose, Dy in mrad, is calculated for each release permit using one of the following equations:

For ground or split-level release/discharge points:

Dy = 3.17E-08 T Z [ DFyi Qi X/Q 1 (7.7) i For elevated release/discharge points:

Dy = 3.17E-08 T Z [ Bi Qi 1 (7.8) i where:

3.17E-08 = conversion factor, y/s.

T = duration of release, s.

DFyi = dose conversion factor for external gamma for nuclide i (Table 7.4), mrad/y per pCi/m 3 .

Qi = the release rate of radionuclide i, pCi/s.

X/Q = the highest calculated annual-average relative concentration for any area at or beyond the unrestricted area boundary for the 3

release type under consideration (Table 7.1), s/m .

Bi = the constant for long term releases (greater than 500 h/y) for each identified noble gas radionuclide accounting for the gamma radiation from the elevated finite plume (Table 7.4), mrad/y per pCi/s.

The location with the highest dose is selected as the critical receptor for each release. This receptor is used in the determination of the cumulative doses in Section 7.4.3.

ODCM Revision 0014 Page 116 of 208 7.4.2 Beta Dose to Air The beta air dose, Dp in mrad, is calculated for each release permit using the following equation:

Dp = 3.17E-08 T Z [ DFpi (Qi X/Q ) ] (7.9) i where:

3.17E-08 = conversion factor, y/s.

T = duration of release, s.

X/Q = the highest calculated annual average relative concentration for any area at or beyond the unrestricted area boundary for the 3

release/discharge point under consideration (Table 7.1), s/m .

The beta-air dose calculated by this method will be used in the cumulative dose calculations discussed in Section 7.4.3.

7.4.3 Cumulative Dose - Noble Gas Quarterly and annual sums of all doses are calculated for each release as described below to compare to the limits listed in ODCM Control 1.2.2.2.

For noble gases, cumulative doses are calculated for gamma and beta air doses.

Doses due to each release are summed with the doses for all previous release in the quarter or year to obtain cumulative quarterly and annual doses.

7.4.4 Comparison to Limits The cumulative calendar quarter and calendar year doses are compared to their respective limits for each release to determine compliance.

ODCM Revision 0014 Page 117 of 208 7.5 CUMULATIVE DOSE 131, 1-133, TRITIUM AND RADIONUCLIDES IN PARTICULATE FORM WITH HALF-LIVES GREATER THAN 8 DAYS 7.5.1 Organ Dose Calculation Organ dose due to 1-131, 1-133, tritium and all radionuclides in particulate form with half-lives of greater than 8 days are calculated for each release permit for the critical receptor. The critical receptor is defined as the receptor with the highest calculated dose of all the receptors defined in Table 7.1. Annual average x/Q and D/Q are calculated using the methodology in Sections 7.9.2 and 7.9.3 using the historical 1977-88 meteorological data (Table 7.2). Pathways considered to exist at these locations are inhalation, ground plane exposure, grass-cow-milk ingestion, grass-cow-beef ingestion and fresh leafy and stored vegetable ingestion. All age groups are considered (adult, teen, child and infant). Dose factors for these age groups and pathways are calculated as described in Section 7.8. For the ground exposure pathway, which has no age or organ specific dose factors, the total body dose will be added to the internal organ doses for all age groups. No credit is taken for radioactive decay.

The general equation for the calculation of organ dose is:

Dorg = 3.17E-08 7 Z T Rpi [ Wp Qi ] (7.10) iP where:

3.17E-08 = conversion factor, y/s.

T = duration of release from release/discharge point under consideration, s.

Rpi = dose factor for pathway P for each identified nuclide i, m2 -mrem/y per pCi/s for ground plane, grass-cow-milk, grass-cow-meat, and vegetation pathways, and mrem/y per pCi/m3 for inhalation and tritium ingestion pathways. Equations for calculating these dose factors are given in Section 7.8.

Wp = dispersion factor for the release/discharge point under consideration and pathway P (Table 7.1).

= X/Q for the inhalation and tritium ingestion pathways,

= D/Q for the food and ground plane pathways, Qi = release rate for radionuclide i from release/discharge point under consideration, pCi/s.

The receptor with the highest dose of all locations, age groups and organs is selected as the critical receptor. The age group with the highest dose for that receptor is selected as the critical age group. The organ dose for the critical age group will be used in the cumulative doses discussed in Section 7.5.2.

ODCM Revision 0014 Page 118 of 208 7.5.2 Cumulative Doses Quarterly and annual sums of all doses are calculated for each release as described below to compare to the limits listed in ODCM Control 1.2.2.3.

For maximum organ dose, cumulative quarterly and annual doses are maintained for each of the eight organs considered. The cumulative dose is obtained by summing the doses for each organ of the critical age group (as calculated in Section 7.5.1) as determined for each release with the organ doses for all previous releases in the quarter or year to obtain the cumulative quarterly and annual doses. Thus, the cumulative organ doses will be conservative values, consisting of doses belonging to various age groups depending on the mix of radionuclides. The highest of these cumulative organ doses is used for the comparison to the limits described in ODCM Control 1.2.2.3.

7.5.3 Comparison to Limits The cumulative calendar quarter and calendar year doses are compared to their respective limits for each release to determine compliance.

ODCM Revision 0014 Page 119 of 208 7.6 GASEOUS RADWASTE TREATMENT 7.6.1 DOSE PROJECTIONS Dose projections will be performed 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.

If the results of the dose projection indicate potential doses in excess of the monthly fraction of the annual dose limit, efforts will be made to minimize future releases.

7.6.2 SYSTEM DESCRIPTION Figure 7.1 shows major elements of the Gaseous Radwaste Treatment System.

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 stack 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.

ODCM Revision 0014 Page 120 of 208 7.7 DOSE CALCULATIONS FOR REPORTING PURPOSES A complete dose analysis utilizing the total estimated gaseous releases for each calendar quarter will be performed and reported as required in ODCM Administrative Control 5.2. Methodology for this analysis is that which is described below, using the quarterly release values. For iodine releases, it will be assumed that half the iodines released are organic iodines, which contribute only to the inhalation dose. All real pathways and receptor locations (as identified in the most recent land use survey) are considered. In addition, actual meteorological data representative of each corresponding calendar quarter will be used to calculate dispersion factors as described in Section 7.9. Stack releases will be considered elevated releases. Radwaste and reactor building releases will be considered split-level releases. Turbine building releases will be treated as ground level.

7.7.1 Noble Gas Dose All measured radionuclides are used to calculate gamma and beta air doses.

The dose is evaluated at the nearest SITE BOUNDARY point in each sector and at other locations expected to be maximum exposure points using a semi-infinite cloud model. 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 BFN.

Radioactive decay is considered in this calculation. The quarterly release is averaged over one year to obtain an average release rate.

3 Rii = Inhalation dose factor, mrem/y per pCi/m . The equation for calculating the inhalation dose factor is given in Section 7.8.13.

ODCM Revision 0014 Page 123 of 208 Qi = adjusted release for nuclide i for location under consideration, pCi.

The initial release is adjusted to account for decay between the release point and the location, depending on the frequency of wind speeds applicable to that sector. Hence, the adjusted release is equal to the actual release decayed for an average travel time during the period.

Ingestion pathways available for consideration are the same as those listed above for Rpi. Equations for calculating ingestion dose factors for tritium are given in Sections 7.8.7 through 7.8.12.

Calculated in the same manner as Qi above.

ODCM Revision 0014 Page 124 of 208 7.7.3 Population Doses For determining population doses to the 50-mile population around the plant, each compass sector is broken down into elements. These elements are defined in Table 7.5. For each of these sector elements, an average dose is calculated, and then multiplied by the population in that sector element.

Dispersion factors are calculated for the midpoint of each sector element (see Table 7.5) using the methodology described in Section 7.9. For population doses resulting from ingestion, it is conservatively assumed that all food eaten by the average individual is grown locally.

The general equation used for calculating the population dose in a given sector element is:

Dosepop Z RATIOp

• POPN

• AGE k 0.001

• DOSEp (7.15)

P where:

RATIOp = ratio of average to maximum dose for pathway P. (Average ingestion rates are obtained from Regulatory Guide 1.109, Table E-4.)

= 0.5 for submersion and ground exposure pathways, a shielding/occupancy factor.

= 1.0 for the inhalation pathway.

= 0.515, 0.515, 0.5, and 0.355 for milk, for infant, child, teen and adult, respectively. (It is assumed that the ratio of average to maximum infant milk ingestion rates is the same as that for child.)

= 1.0, 0.90, 0.91, 0.86 for beef ingestion, for infant, child, teen and adult, respectively.

= 1.0, 0.38, 0.38, 0.37 for vegetable ingestion, for infant, child, teen and adult, respectively. (It is assumed that the average individual eats no fresh vegetables, only stored vegetables.)

POPN = the population of the sector element, persons (Table 7.6).

AGE = fraction of the population belonging to each age group.

= 0.015, 0.168, 0.153, 0.665 for infant, child, teen and adult, respectively (fractions taken from NUREG/CR-1004, Table 3.39).

0.001 = conversion from mrem to rem.

DOSEp = the dose for pathway P to the maximum individual at the location under consideration, mrem. For ingestion pathways, this dose is multiplied by an average decay correction to account for decay as the food is moved through the food distribution cycle. This average decay correction, ADC, is defined as:

ADC = exp(-Xit), for milk and vegetables, where:

Xi = decay constant for nuclide i, s.

t = distribution time for food product under consideration (from Regulatory Guide 1.109, Table D-l).

= 1.21E+06 s (14 d) for vegetables.

= 3.46E+05 s (4 d) for milk.

ODCM Revision 0014 Page 125 of 208 exp(-Xit) Xitcb ADC = , for meat, 1 - exp(-Xi tcb) where:

Xi = decay constant for nuclide i, s.

t = additional distribution time for meat, over and above the time for slaughter to consumption described in Section 7.8.3, 7d (from Regulatory Guide 1.109, Table D-2).

tcb = time to consume a whole beef, as described in Section 7.8.3.

For beef ingestion, the additional factors in the calculation of ADC negate the integration of the dose term over the period during which a whole beef is consumed, for the calculation of population dose. This assumes that the maximum individual freezes and eats a whole beef, but the average individual buys smaller portions at a time.

Population doses are summed over all sector elements to obtain a total population dose for the 50-mile population.

7.7.4 Reporting of Doses The calculated quarterly doses and calculated population doses described in this section are reported in the Annual Radioactive Effluent Release Report as described in ODCM Administrative Control 5.2 7.7.5 Dose to a MEMBER OF THE PUBLIC Inside the SITE BOUNDARY The Basis for ODCM Control 1.2.2.1 states that for MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy factor of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric dispersion factor above that for the SITE BOUNDARY.

The highest dose to a MEMBER OF THE PUBLIC will consider the effects of effluent pathways (onsite and offsite) and direct radiation from plant operating activities.

The dose to this hypothetical MEMBER OF THE PUBLIC will be determined on an annual basis (using the methodology above) to ensure that the actual exposure to any individual is less than 100 mrem/year. The results of this review will be included in the Annual Radiological Effluent Report pursuant to ODCM Administrative Control 5.2.

ODCM Revision 0014 Page 139 of 208 7.9 DISPERSION METHODOLOGY Dispersion factors are calculated for radioactive effluent releases using hourly average meteorological data collected onsite.

Meteorological data for ground level releases consist of windspeed and direction measurements at 10m and temperature measurements of 10m and 45 m.

Hourly average meteorological data for the ground level portion of a split level release 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 release uses wind speeds and directions measured at the 46m level and temperature measurements at 45m and 90m.

Hourly average meteorological data for the elevated releases consist of windspeed and directions measured at 93m. Stability class D is assumed to persist during the entire period for elevated releases, except for the dose calculations described in Section 7.7 when all stability classes will be used to evaluate the elevated results.

Meteorological data are expressed as a joint-frequency distribution of wind speed, wind direction, and atmospheric stability for each release level (ground, split and elevated). The joint-frequency distributions which represent the historical meteorological data for the period January 1977 to December 1988 are given in Table 7.3.

The wind speed classes that are used are as follows:

Number Range (m/s) Midpoint (m/s) 1 <0.3 0.13 2 0.3-0.6 0.45 3 0.7-1.5 1.10 4 1.6-2.4 1.99 5 2.5-3.3 2.88 6 3.4-5.5 4.45 7 5.6-8.2 6.91 8 8.3-10.9 9.59 9 >10. 9 10.95 The stability classes that will be used are the standard Pasquill A through G classifications. The stability classes 1-7 will correspond to A=1, B=2, ... ,

G=7.

fk = joint relative frequency of occurrence of winds in windspeed class j and stability class k, blowing toward this exposure point, expressed as a fraction.

DR = relative deposition rate, m-I (from Figure 7.5). The choice of figures is governed by the effective release height calculation described in Section 7.9.4. A linear interpolation is used for effluent release heights that fall in between the given curves.

x = downwind distance, m.

n = number of sectors, 16.

2nx/n = sector width at point of interest, m.

ODCM Revision 0014 Page 142 of 208 7.9.4 Effective Release Height 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 he = hs + hpr - ht -c where:

c = downwash correction factor for low relative exit velocity,

= 3(l.5-Wo/u)d, where:

Wo = the vertical plume exit velocity, m/s.

u = mean wind speed at 93m, m/s.

d = inside diameter of the release point, m.

NOTE: If c is less than zero, it is set equal to zero.

hpr = plume rise above the release point, m.

hs = physical height of release point, m.

ht = maximum 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 split-level as follows:

Case 1 - elevated if Wo/u Ž 5.

Case 2 - ground level (he = 0) if Wo/u

• 1.

Case 3 - mixed mode if 1 < wo/u < 5.

where:

u = mean wind speed at 46m, m/s.

Under the split-level dispersion approach, a model that requires two JFDs (one for elevated releases and one for ground level releases) is used. The summation of the elevated and ground level JFDs account for the total period of record. For Case 3 (mixed-mode), releases are considered to be elevated 100(1-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 < Wo/u

• 1.5 Et = 0.3 - 0.06(Wo/u) for 1.5 < Wo/u

• 5

ODCM Revision 0014 Page 196 of 208 8.0 TOTAL DOSE To determine compliance with 40 CFR 190, the annual dose contributions to the maximum individual from BFN 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, summing the total body air submersion dose, and the maximum (critical) organ dose (except thyroid) from gaseous effluents; the total body dose, and maximum organ dose (except thyroid) from liquid effluents for each quarter calculated in accordance with Sections 6.6 and 7.7. 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 REMP outlined in Section 9.0. These quarterly sums are then conservatively summed for the four calendar quarters to estimate the maximum individual dose for the year.

This dose is compared to the limit in Control 1.2.3, i.e., 25 mrem per year to the total body or any organ (except thyroid), to determine compliance.

The total annual thyroid dose to the maximum individual will be conservatively estimated in the following manner. For each calendar quarter, a total dose will be obtained by summing the total body gaseous submersion dose, the gaseous thyroid dose, the liquid total body dose, and the liquid thyroid dose. To this sum for each quarter is added any identifiable increase in direct radiation dose levels attributable to the plant as determined by the REMP outlined in Section 9.0. These quarterly sums are then added together to estimate the maximum individual thyroid dose for the year. This dose is compared to the limit in Control 1.2.3, i.e., 75 mrem per year to determine compliance.

ODCM Revision 0014 Page 198 of 208 9.1 MONITORING PROGRAM DESCRIPTION A Radiological Environmental Monitoring Program (REMP) as described in Tables 9.1, 9.2, and 9.3 and in Figures 9.1, 9.2, and 9.3 shall be conducted. Results of this program shall be reported in accordance with ODCM Administrative Control 5.1.

The atmospheric REMP shall consist of 11 monitoring stations from which samples of air particulates and radioiodine shall be collected.

The terrestrial monitoring program shall consist of the collection of milk, soil, drinking water, and food crops. In addition, direct gamma radiation levels will be measured at 40 or more locations in the vicinity of the plant.

The reservoir sampling program shall consist of the collection of samples of surface water, sediment, and fish.

9.2 DETECTION CAPABILITIES Analytical techniques shall be such that the detection capabilities listed in Table 2.3-2 are achieved.

9.3 LAND USE CENSUS A land use survey shall be conducted in accordance with the requirements in Control 1.3.2. The results of the survey shall be reported in the Annual Radiological Environmental Operating Report.

9.4 INTERLABORATORY COMPARISON PROGRAM Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program which has been approved by the NRC.

A summary of the results obtained in the intercomparison shall be included in the Annual Radiological Environmental Operating Report.

If analyses are not performed as required corrective actions taken to prevent a recurrence shall be reported in the Annual Radiological Environmental Operating Report.
