A. INTRODUCTION

Appendix I, "Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion

'As Low As Is Reasonably Achievable'

for Radioactive Material in Light-Water-Cooled Nuclear Power Reactor Effluents," to 10 CFR Part 50 provides numerical guidance for radioactive effluent design objectives and technical specification requirements for limiting conditions of operation for light-water-cooled nuclear power plants.To implement Appendix I, the NRC staff has developed a series of guides that provide methods.acceptable to the staff for the calculation of preoperational estimates of effluent releases, dispersion of the effluent in the atmosphere and different water bodies, and estimation of the associated radiation doses* to man. This guide describes basic features of these calculational models and suggests parameters for the estimation of radiation doses to man from effluent releases.The methods used herein are general approaches that the NRC staff has developed for application in lieu of specific parameters for individual sites. The use of site-specific values by the applicant is encouraged.

However, the assumptions and methods used to obtain these parameters should be fully described and documented.

Portions of this guide supersede Regulatory Guide 1.42, Revision 1, "Interim Licensing Policy on as Low as Practicable for Gaseous Radioiodine Releases from Light-Water-Cooled Nuclear Power Reactors," which has been withdrawn.

B. DISCUSSION

Appendix I to 10 CFR Part 50 provides guidance on the doses to members of the general public resulting from effluent releases that may be considered to be as low as is reasonably achievable.

This guide describes basic features of the calculational models and assumptions in use by the NRC staff for the estimation of doses.Appendix A of this guide describes suggested models and assumptions for calculating the estimated doses to man from discharges to the hydrosphere.

Appendix B of this guide describes suggested models and assumptions for calculating doses from noble gases discharged to the atmos-phere, and Appendix C. gives models and assumptions for estimating doses from radioiodines and other radionuclides released to the atmosphere.

Appendix D describes the models and assumptions for calculating population doses (man-rem and man-thyroid-rem)

from radionuclide releases to the atmosphere and hydrosphere.

Appendix E presents tabular data pertaining to two or more of the other appendices.

Appendix F provides a discussion of, and derivation for, the I function used in computing gamma doses from elevated noble gas releases.In providing guidance for implementing Section II of Appendix I, the.NRC staff -has made use of the maximum exposed individual approach.

In this approach the numerical design objectives of Section II are compared to the calculated radiation exposures to maximum individuals in each of four age groups.The population is considered to be made up of infants (0 to 1 year), children (1 to 11 years), teenagers

(11 to 17 years), and adults (17 years and older). For the purpose of evaluating dose commitment, the maximum infant is assumed to be newborn, the maximum child is taken to be 4 years old, the maximum teenager is taken to be 14 years old, and the maximum adult is-taken to be 17 years old.Maximum individuals are characterized as "maximum'" with -regard to food consumption, occupancy, and other usage of the region in the-vicinity of the plant site and as such represent individuals with habits representing reasonable deviations from the average for the population in general.In all physiological and metabolic respects the maximum exposed individuals are assumed to have those characteristics that represent the averages for their corresponding age group in the general In this guide, the term "dose," when applied to individuals, is used instead of the more precise term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU). When applied to the evaluation of internal'deposition of radioactivity, the term "dose," as used here, includes the prospective dose component arising from retention in the body beyond the period of environmental exposure, i.e., the dose commitment.

The dose commitment is evaluated over a period of 50 years.11.109-I

population.

Although specific individuals will almost certainly display dietary, recreational, and other living habits considerably different from those suggested here, and actual physiological and metabolic parameters may vary considerably, the NRC staff considers the maximum exposed individual to be a well-defined reference for implementation of Section II of Appendix I. The characterization of maximum exposed individuals is subject to continuing review by the NRC staff, and the applicant is encouraged to use information and data applicable to a specific region or site when possible.

Where site-specific information and data is used, its justification should be documented for the NRC staff's review.Since the radiation dose commitment per unit intake of a given radionuclide usually varies as a function of-age, four sets.of internal dose conversion factors have been calculated.

These dose factors are appropriate for the four different age groups defined above. Specifically, these dose factors are based on continuous intake over a one-year environmental exposure period and an associated dose commitment extending over a 50-year period from initiation of intake.The models and assumptions described in Appendices A, B, C, and D of this guide are accept-able to the NRC staff for calculating doses to individuals and populations.

If other models are selected, they should include the same exposure pathways considered in the models described in this guide. The assumptions and methods used should be fully described and documented.

As discussed in Section III.A.2 of Appendix I-to 10 CFR Part 50, the applicant may take intoaccount any real phenomena or actual exposure conditions.

Such conditions could include actual values for agricultural productivity, dietary habits, residence times, dose attenuation by'structures, measured environmental transport factors (such as bioaccumulation factors), or similar values actually determined for a specific site. The applicant should provide enough information on the measurements or other methods used to derive these substitute values to enable the NRC staff to evaluate their validity.C. REGULATORY

POSITION Equations are provided below by which the NRC staff will estimate radiation exposure for maximum individuals and the population within 50 miles. These equations are appropriate for the exposure pathways that the staff routinely considers in its evaluations.

In addition, other exposure pathways that may arise due to unique conditions at a specific site should be considered if they are likely to provide a significant contribution to the total dose. A pathway is con-sidered significant if a conservative evaluation yields an additional dose increment equal to or more than 10 percent of the total from all pathways considered in this guide.1. Doses from Liquid Effluent Pathways The NRC staff will calculate radiation doses from potable water, aquatic food, shoreline deposits, and irrigated food pathways by using the following equations, which are described in detail in Appendix A of this guide.a.

APPENDIX A METHODS FOR CALCULATING

DOSES TO MAN FROM LIQUID EFFLUENT PATHWAYS The equations for estimating radiation exposureto man from four principal exposure path-ways in the aquatic environment (potable water, aquatic foods, shoreline-deposits, and irrigated foods) are listed in Section C, "Regulatory Position," of this guide.1. Generalized Equation for Calculating Radiation Dose via Liquid Pathways.Equation (A-l) is the generalized equation for calculating the radiation dose to man via liquid effluent pathways.Raipj Cip UapD aipj (A-1)where C. is the concentration of nuclide i in the media of pathway p, in pCi/x, pCi/kg, or pCi/m 2;Daipj is the dose factor, specific to age group a, radionuclide i, pathway p, alp, and organ j. It represents the dose due to the intake of a radionuclide, in mrem/pCi, or from exposure to a given concentration of a radionuclide in 2'sediment, in mrem per hr/pCi per m R ..is the annual dose to organ j of an individual of age group a from nuclide i alp,] via pathway p, in mrem/yr; and Ua is the exposure time or intake rate (usage) associated with pathway p for ap age group a, in hr/yr, Z/yr or kg/yr (as appropriate).

The three factors, making up Equation (A-l) are discussed in the following sections, most of which were taken directly from the WASH-1258 report (Ref. 1). (An updated version of the portion of the WASH-1258 report describing models and computer programs is contained in the. BNWL-1754 report (Ref. 2).)a. Radionuclide Concentrationin Environmental Media (Cip)The concentrations in environmental media of interest can be estimated from the mixing ratio Mp, the discharge flow F, the radionuclide release rate Qi' and other terms presented in.*the pathway equations that appear later in this discussion..

b. Usage (U Y.The second term of Equation.(A-l)

is the usage term Ua. Usage is expressed as a ap-consumption rate in kg/yr or liters/yr or as an exposure time in hr/yr, as appropriate for the pathway and age group under consideration.

The NRC staff encourages the use of site-specific data, whenever possible.

Such data should be documented.

In the absence of site-specific data, however, the usage values (consumption rates and exposure times) presented in Appendix E, Table E-5, are recommended.

c. Dose Factor (D aipj Dose factors for internal exposure via ingestion are provided in Appendix E, Tables E-ll, 12, 13, and 14. Appendix E also provides further discussion of the data, models, and assumptions used.Material deposited from sedimentation in an aquatic system represents a fairly large, nearly uniform thin sheet of contamination.

The factors for converting surface contamination given in pCi/m2 to the dose rate at one meter above a uniformly contaminated plane have been described by Soldat and others (Refs. 3 and 4). Dose factors for exposure to soil sediment have units of mrem/hr per pCi/m2 and are presented in Appendix E, Table E-6.1.109-11

2. Equations for Liquid Pathways This section develops the equations required for the liquid pathway models. The principal difference between pathways is the manner in which the radionuclide concentrations are calculated.

The doses from the four pathways should be added to determine the total dose.a. Potable Water The annual dose from ingestion of water is calculated from Equation (A-2) below: M Ua-Rapj = 1100 pF Qia pjeXp(-,t p) (A-2)Symbols for this equation were defined earlier, in Section C.l of this guide.The summation process adds the dose contribution from each nuclide to yield the total dose for the pathway-organ combination selected.

The expression

(1100 QiM p/F)exp(-xit p) yields the concentration of nuclide i at the time the water is consumed, in pCi/X. This concentration is the term Cip in Equation (A-l). As a minimum, the transit time tp may be set equal to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to allow for radionuclide transport through the water purification plant and the water distribution system (Ref. 5). The transit time should be increased as appropriate to: allow for travel from the point of effluent release to the water purification plant intake. Credit may be taken for radionuclide removal by water purification processes using techniques such as those outlined in Reference

3.It should be noted that, depending on the.hydrological dispersion model employed, the-mixing ratio, Mpor. dilution factor may not be explicitly defined. In those instances (e.g.:, buildup of activitykin a cooling pond), the relative concentration in the mixed stream (comparedc to the effluent co,6centration)

may be supplied as a function of the radiological decay constant, with any potential'

effl'uent recycling taken into account. Suggested hydrological dispersion models are presented in Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I." b. Aquatic Foods The concentrations'of radionuclides in aquatic foods are assumed to be directly related to the concentrations of the nuclides in water. Equilibrium ratios between the two concentrations, called bioaccumulation factors in this guide,.can be found in the literature (Ref. 6). The inclusion of the bioaccumulation factor Bip in Equation (A-2) yields Equation (A-3), which is suitable for calculating the internal dose from consumption of.aquatic foods.U M R apj =1100 F .QiBipD ai pjexp(-itp)

.(A-3)Values of B are given in Table A-l; the other. parameters have been previously defined. The ip methodology presented in Reference

7 for the development of site-specific freshwater bioaccumula- tion factorsis considered to-be acceptable by the NRC staff.The transit time tp may be set equal to 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s* to allow for radionuclide decay during transit through the food chain, as well as during food preparation.

c. Dose from Shoreline Deposits The calculation of individual dose from shoreline deposits is complex since it involves estimation of sediment load, transport, and concentrations of radionuclides associated with Here, and in a number of other instances, the NRC staff has found it necessary to set forth guidance as to a parameter value in the absence ofempirical data. In such instances judgments have been made after considering values assumed by others and model sensitivity to the parameter value in question.

In this particular instance, the total body dose from fish ingestion, for a typical situation, was found to vary by less than a factor of two for a range of environmental transit times of from one to seven days.1.109-12 TABLE A-1 BIOACCUMULATION

suspended and deposited materials.

One method of approaching this problem was presented in the Year 2000 Study (Ref. 3). Based on this model, an estimate of the radionuclide concentration in shoreline sediments can be obtained from the following expression:

C.s = Kc Ciw[l -exp(-Aitb)] (A-4)Cis =i where C is is.the concentration of nuclide i in sediment, in pCi/kg;Ciw is the concentration of nuclide i in water adjacent to the sediment, in pCi/liter;

K is an assumed transfer constant from water to sediment, in liters/kg per hr;tb is the length of time the sediment is exposed to the contaminated Water, nominally

15 years (approximate midpoint of facility operating life), in hours; and A. is the decay constant*

of nuclide i, in hours-l. In the original evaluation of the equation, xi was chosen to be the radiological-decay constant.

The true value should include an as yet unknown "environmental" removal constant.The value of Kc was derived for several radionuclides by using data from water and sediment samples collected over a period-of several years.in the Columbia River between Richland, Washington,..and the river mouth and in Tillamook Bay, Oregon, 75 km south of the river mouth (Refs. 9 and 10). Since the primary use of the equation is to facilitate estimates of the exposure rate from gamma.iemitters one meter above the sediment, an effective surface contamina- tion was estimated.

This surface contamination was assumed to be contained within the top 2.5 cm (1 in.) of sediment (with a mass of 40 kg/m 2 of surface).

The dose contribution from the radionuclides at depths below 2.5 cm was ignored. The resulting equation is Si = lOOTiCiwW[l

-exp(-xitb)] (A-5)where Si is the "effective" surface contamination, in.pCi/m 2 , that is used in subsequent calculations;

Ti is the radiological half-life of nuclide i, in days;W is a shore-width factor that describes the geometry of the exposure;

and 100 is equal to [Kc (/kg-hr)*40(kg/m2)*

24(hr/day)/0.693], in -/m2-day.Shore-width factors were derived from experimental data (Ref.. 11) and are summarized in Table A-2. They represent the fraction of the dose from an infinite plane source that is estimated for these shoreline situations.

The combination of Equations (A-4) and (A-5) into the general Equation (A-l) leads to Equation (A-6) below for calculation of radiation dose from exposure to shoreline sediments.

Rapj = Uap i.D aipj = 100 UapW C Ti D aipj[l -exp(-xitb)] (A-6)As in the development of Equation (A-2), the expression

(1100 Qi M p/F)exp(-it p) may be substituted for C .This results in the following relationship:

Separate expressions are presented for tritium because of its unique environmental behavior.(1) Vegetation The concentration of radioactive material in vegetation results frol deposition onto the plant foliage and from uptake from the soil of activity deposited on the ground. The model, used for estimating the transfer of radionuclides from irrigation water to crops through water deposited on leaves and uptake from soil was derived for-a study of the potential doses to people from a nuclear power complex in the year 2000 (Ref. 3).The equation for the model (for radionuclides except tritium) is presented below in slightly modified form. The. first term in brackets relates to the concentration derived from direct foliar deposition during the growing season. The second term relates to uptake from soil and reflects the long-term deposition during operation of the nuclear facility.

Thus, for a uniform release rate, the concentration Civ of radionuclide i in the edible portion of crop species v, in units of pCi/kg,"is given by:.Civ d d [r[l -exp(-xEite)]

Values for Biv are in Table E-l.The deposition rate, di, from irrigated water is defined by the relation di = Ciw I (water deposition). (A-9)where Ciw is the concentration of radionuclide i in water used for irrigation, in pCi/liter, and I is the average irrigation rate, in liters/m2

The radionuclide concentration in animal products CiA in terms of pCi/liter or pCi/kg is proportional to the animal's intake of the radionuclide in feed or forage (sub-script F) and in water (subscript w): CiA = F iA[CiFQF + Q (A-ll)The second set of terms in the brackets in Equation (A-1l) can be omitted if the animal does not drink contaminated water. Values for QF and QAw are presented in Appendix E, Table E-3.

It should be noted that the two components of Equation (A-12) imply that contribu-tions from the-individual vegetable and animal products have already been summed. In actual.use, it will be necessary to compute separately the milk and meat portions of the dose due to animal products (also applicable to Equation (A-16)).For tritium, the concentration in animal products (milk or meat) is given by the following equation: CA = Fa(CvQF + CAwQAw) (A-14)where the terms are defined in Section C, "Regulatory Position."

APPENDIX B MODELS FOR CALCULATING

DOSES FROM NOBLE GASES DISCHARGED

TO THE ATMOSPHERE

The following analytical models are used for calculating doses from exposure to noble gases discharged to the atmosphere.

Separate models are given for air and tissue doses due to gamma and beta rays. Except for the case of noble gas doses resulting from elevated releases, all models assume immersion in a semi-infinite cloud.1. Annual Gamma Air Dose* from Noble Gas Releases from Free-Standing Stacks More Than 80 Meters Hih: Slade (Ref. 1) describes a derivation of equations for estimating annual air doses from photon emitters dispersed in the atmosphere.

The following expression can be used for calculating annual doses:~260 D DY(r,e) = 2--0 U- fns QniA (B-l)n n s k nk Symbols for this equation were defined earlier, in Regulatory Position C.2.a of this guide.A discussion of, and derivation for, the I function are presented in Appendix F of this guide.The photons are combined into energy groups, and each photon intensity within a group is weighted by its energy and energy absorption coefficient.

Thus, the effective fraction of disintegrations of the nuclide i yielding photons corresponding to the photon energy group k, Aki, is determined to be Aki = X [AmEma(Em)]/[Ekla(Ek)] (B-2)m where A is the fraction of the disintegrations of nuclide i yielding photons m .of energy Em;Em is the energy of the mth photon within the kth energy group, in MeV; and Wa (Em) is the energy absorption coefficient in air associated with the photon energy Em, in m All other parameters are as previously defined. The summation is carried out over all photons-within.energy group k. Data for the photon energies and abundances for most of the noble gas nuclides were taken from Reference

2. For radionuclides not contained in Reference

2, data were obtained from Reference

3.Decay during travel from the point of release to the receptor is Qni Q Qi exp(-xir/un) (B-3)., The term "gamma.air dose" refers to the components of the air dose associated with photons emitted during nuclear and atomic transformations, i.e., gamma and x-rays. Annihilation and bremsstrahlung photon radiations are possible contributors to this component of the air dose.1.109-19 where Qi is the initial release rate of nuclide i, in Ci/yr;r is the distance from the source to the receptor, in m; and-I Xi is the decay constant of nuclide i, in sec All other parameters are as previously defined.2. Annual Gamma Air Dose from All Other Noble Gas Releases and Annual Beta Air Dose* from All Noble Gas Releases Plumes of gaseous effluents are considered semi-infinite in the case of ground-level noble gas releases.

The annual average ground-level concentration of radionuclide i at location (r,e)is. determined from xi(r,e) = 3.17 x 104 Q[x/Q] D(r,e) (8-4)where x.(r,e) is the annual average ground-level concentration of nuclide i at the 3 distance r in the sector at angie e from the release point, in pCi/mi , and[x/Q]D(r,e)

is the annual average gaseous dispersion factor (corrected'for radioactive decay) in the sector at angle ,3 it the distance r from the release point, in sec/m 3.(See Regulatory Guide 1,111 for atmospheric dispersion models.)All other parameters are as previously defined.The associated annual gamma or beta air dose is then D'(r,e) or D 6 (r,e) = xi(re)(DFi or DF) (B-5)where the terms are as~defined in Regulatory Position C.2.b.Table B-1 presents a tabulation of the dose factors for the noble gases of interest.3. Annual Total Body and Skin Doses from Noble Gas Effluents It is also necessary to determine annual doses to real individuals in unrestricted areas.The staff computes the total body dose from external radiation at a depth of 5 cm into the body and the skin dose at a depth of 7 mg/cm2 of tissue (Ref. 4).**a. Releases from Free-Standing Stacks More Than 80 Meters High The annual total body dose is computed as follows: DT(r,e) = 1.11 x SF I DY(r,O)exp[-T(Ek)td1 (B-6)The term "beta air dose" refers to the component of the air dose associated with particle emissions during nuclear and atomic transformations, i.e., o+, B-, and conversion electrons.

TO THE ATMOSPHERE

1. Annual External Dose from Direct Exposure to Activity Deposited on the Ground Plane The ground plane concentration of radionuclide i at the location (r,e) with respect to the release point may be determined by CG(r,O) = [1.0 x 1012.1 [6i(re) Qi]1 -1 1 [1 -exp(_xitb)]. (C-l)where CG(r,e) is the ground plane concentration of the radionuclide i in the sector at I angle 0 at the distancer from the release point, in pCi/m2 Q. is the annual'release rate of nuclide i to the atmosphere, in Ci/yr;tb is the time period over which the accumulation is evaluated, which is 15 years (mid-point of plant operating life). This is a simplified method of approximating the average deposition over the operating lifetime of the facility;6i(r,e) is the annual average relative deposition of effluent species i at location (r,e), considering depletion of the plume during transport, in m-2;x is the radiological decay constant for nuclide i, in yr-; and 1.0 x 1012 is the number of pCi per Ci.The annual dose resulting from direct exposure to the contaminated ground plane, from all radionuclides, is then DG(r,e) = 8760 SF CG(r,e)DFGi (C-2)where the terms-are defined in Regulatory Position C.3.a of this guide.Values for the open field ground plane dose conversion factors for the skin and total body are given in Appendix E,'.Table E-6. The annual dose to all other organs is taken to be equivalent to the total body dose. The factor SF is assumed to have a value of 0.7, dimensionless.

Does not include noble gases.1.109-24 K, i,, 2. Annual Dose from Inhalation of Radionuclides in Air The annual average airborne concentration of radionuclide iat the location (r,e) with res-pect to the release point may be determined as xi(r,e) = 3.17 x 104 Qi[x/Q] D(r,e)(C-3)where Qi is the release rate of nuclide i to the atmosphere, in Ci/yr;Xi(r,e) is the annual average ground-level concentration, of nuclide i in air in sector e at distance r, in pCi/m3;[x/Q]D(r,o)

3.17 x l04 3 is the annual average atmosphere dispersion factor, in sec/m (see Regulatory Guide 1.111). This includes depletion (for radioiodines and particulates)

and radioactive decay of the plume; and is the number of pCi/Ci divided by the number of sec/yr.The annual dose associated with inhalation of all radionuclides, to organ j of an individual in age group-a, is then 0.A (r,e) = R Zx.(r,e)DFA.

ja a I ja (C-4)Values for DFAija are given in Appendix E, Tables E-7 through E-l0; values for Ra are given in Appendix E, Table E-5. All other symbols are as defined earlier in Regulatory Position C.3.b.3. Concentrations of Airborne Radionuclides in Foods The concentration of radioactive material in vegetation results from deposition onto the plant foliage and from uptake of activity initially deposited on the ground. The model used for estimating the transfer of radionuclides from the atmosphere to food products is similar to the model developed for estimating the transfer of radionuclides from irrigation water given in Appendix A of this guide.a. Parameters for.Calculating Nuclide Concentrations in Forage, Produce, and Leafy Vegetables For all radioiodines and particulate radionuclides, except tritium and carbon-14, the concentration of nuclide i in and on vegetation at the location (r,e) is estimated using Cv(r,e) =di (r,e) tr[l -exp(-AEi te)]+Biv [ -exp(-xitb)]

_2 P X i exp (- i th )(c-5)See Regulatory Position C.1 of this guide for definitions of terms. Values for the parameters r, te, Yv' P, and th are provided in Appendix E, Table E-15. For the parameters te, Yv and th' different values are given (in Appendix E) to allow the use of Equation (C-5) for different purposes:

estimating concentrations in produce consumed by man; in leafy vegetables consumed by man; in forage consumed directly as pasture grass by dairy cows, beef cattle, or goats; and in forage consumed as stored feed by dairy cows, beef cattle, or goats.1.109-25 The deposition rate from the plume is defined by di(r,e) = 1.1 x 1086i(r,e)Qi (C-6)where d.(r,e) is the deposition rate of radionuclide i onto ground at location (r,e), in pCi/m 2-hr;6i(r,e) is th6 relative deposition of radionuclide i, considering depletion and 1 2 decay in transit to location (r,e), in m- (see Regulatory Guide 1.111); and 1.1 x 1O8 is the number of pCi per Ci (10 2) divided by the number of hours per year (8760).For radioiodines, the model considers only the elemental fraction of the effluent.

The deposition should be computed only for that fraction of the effluent that is estimated to be elemental iodine. Measurements at operating facilities indicate that about half the radioiodine emissions may be considered nonelemental (Ref. 1). With this consideration included, Equation (C-6) for radioiodine becomes di(r,e) = 5.5 x 1076i(r,e)Qi

6.(C-7)where is the total (elemental and nonelemental)

radioiodine emission rate. The retention factor r for elemental radioiodine on vegetation should be taken as unity, since the experimental measurements (Refs. 1, 2, and 3) used to evaluate this transfer mechanism consisted of direct comparison of the gross radioiodine concentration on vegetation and the concentration in air (Refs. 4 and 5).For radioiodines, the deposition model is based only on the dry deposition process. Wet.deposition, including "washout" of the organic and non-organic iodine fractions, should be con-sidered at some sites depending on the meteorological conditions (see Regulatory Guide 1.111).For particulates, the deposition model considers both wet and dry deposition.

There is also a retention factor (r of Equation (C-5)) that accounts for the interception and capture of the deposited activity by the vegetative cover. A value of 0.2 is taken for this factor (Refs. 6 and 7). All nuclides except noble gases, tritium, carbon-14, and the iodines are treated as particulates.

Carbon-14 is assumed to be released in oxide form (CO or C0 2). The concentration4of carbon,14 in vegetation is calculated by assuming that its ratio to the natural carbon in vegetation is the.same as the ratio of carbon-14 to natural carbon in the atmosphere surrounding the vegetation (see Refs. 8 and 9). Also, in the case of intermittent releases, such as from gaseous waste decay tanks, the parameter p is employed to account for the fractional equilibrium ratio achieved.

The parameter p is defined as the ratio of the total annual release time (for C-14 atmospheric releases)to the total annual time during which photosynthesis occurs (taken to be 4400 hrs), under the condition'that the value of p should never exceed unity. For continuous C-14 releases, p is taken to be unity. These considerations yield the following relationship:

C 4 (r,e) = 3.17 x 10 7 pQl 4[x/Q](r,e)

0.11/0.16= 2.2 x 10 7 pQ 1 4[X/Q)(r,e) (C-8)where C 4 (r,e) is the concentration of carbon-14 in vegetation grown at location (r,e), in pCi/kg;Q14 is the annual release rate of carbon-14, in Ci/yr;p is the fractional equilibrium ratio, dimensionless;

0.11 is the fraction of total plant mass that is natural carbon, dimensionless;

1. 109-26

0.16 is.equal to the concentration of natural carbon in the atmosphere, in g/m and 3.17 x 107 is equal to (1.0 x lO 1 2 pci/Ci)(l.0

x 103 g/kg)/(3.15 x 10 7 sec/yr).The concentration of tritium in vegetation is calculated from its concentration in the air surrounding the vegetation.

Using the method described in Reference

10, the NRC staff derived the following equation: c'(r,). 3.17 x 10 7 QT[x/Q(rKe)(0.75)(0.5/H)

= 1.2 x 107 QT[x/Q](r,e)/H (C-9)where C (r,e) is the concentration of tritium in vegetation grown at location (r,e), in pCi/kg;H is the absolute humidity of the atmosphere at location (r,e), in g/m3 QT is the annual release rate of tritium, in Ci/yr;0.5 is the ratio of tritium concentration in plant water to tritium concentration in atmospheric water, dimensionless;

and 0.75 is the fraction of total plant mass that is water, dimensionless.

b. Parameters for Calculating Nuclide Concentrations in Milk The radionuclide concentration in milk is dependent on the amount and contamination level of the feedconsumed by the animal. The radionuclide concentration in milk is estimated as C'(re) = vC(r,)Q exp(-xitf) (C-10)where Cm(r,e) is the concentration in milk of nuclide i, in pCi/liter;

Cv(r, e) is the concentration of radionuclide i in the animal's feed, in pCi/kg;Fm is the average fraction of the animal's daily intake of radionuclide i which appears in each liter of milk, in days/liter (see Appendix E, Tables E-l and E-2 for cow and goat data, respectively;

Parameters for Calculating Nuclide Concentration in Meat As in the milk pathway, the radionuclide concentration in meat is dependent on the amount and contamination level of the feed consumed by the animal. The radionuclide concentra- tion in meat is estimated as F(r,e) FfCi(r,e)QF

POPULATION

DOSES FROM NUCLEAR POWER PLANT EFFLUENTS Calculation of the annual population-integrated total body and thyroid doses* should be performed for the three effluent types identified in this guide. These doses should be evaluated for the population within a 50-mile radius of the site, as specified in paragraph D,Section II of-Appendix I to 10 CFR Part 50.For the purpose of calculating the annual population-integrated dose, the 50-mile region should be divided into a number of subregions consistent with the nature of the region. These subregions may represent, for example, the reaches of a river or land areas over which the appro-priate dispersion factor is averaged.

Dispersion factors, population data, and other information describing existing or planned uses of the subregions should be developed.

1. General Expressions for Population Dose For pathways in which the permanent and transient population of the subregion can be con-sidered to be exposed to the average radionuclide concentrations estimated for the subregion, ,the annual population-integrated dose is calculated as follows: D~j = O.Ol Z Djdafda (D-l)-d a where Djda is the annual dose to organ j (total body or.thyroid)

of an average individual of age group a in subregion d, in mrem/yr;SP is the annual population-integrated dose to organ j (total body or thyroid), in man-rems or thyroid man-rems;fda is the fraction of the population in subregion d that is in.age group a;P d is the population associated with subregion d; and 0.001 is the conversion factor from mrem to rem.'The annual dose to the total body or thyroid of an average individual should be evaluated with the usage factors of Table E-4 of Appendix E. Models and equations for the detailed dose calculations are presented in Appendices A, B, and C of this guide. The annual population- integrated doses from ingestion of potable water, inhalation of airborne effluents, and external exposure to airborne or deposited radionuclides should be evaluated.

In addition to the pathways for which equations are presented in Appendices A, B, and C, other exposure pathways should be evaluated if conditions at a specific site indicate that they might provide a significant contri-bution to the total population dose from all pathways.

In this context, a significant contribu-tion is defined as 10 percent or more.For pathways that involve food products produced in the subregion, the food products may be distributed to other areas for consumption.

For all the food that is produced within the 50-mile radius, the radioactivity concentrations are averaged over the entire area by weighting the concentrations in each subregion by the amount produced in-each subregion.

This average concentra- tion is used in calculating the population doses. The 50-mile average concentration of.nuclide in food p is computed as ip = (1/Vp) exp(-x itp) P Cdipvdp (D-2)The population-integrated dose is the summation of the dose received by all individuals and has units of man-rem when applied to the total body dose and units of man-thyroid-rem when applied to the summation of thyroid dose.-1.109-30

where is the average concentration over subregion d of the nuclide i in pathway p, in pCi/kg or pCi/liter (see Appendices A and C of this guide for models and equations for calculation of pathway concentrations);

C ip is the 50-mile average concentration of nuclide iin pathway p, inpCi/kg or pCi/liter;

t is the transport time of the food medium p through the distribution system, p in days (Table D-1 presents estimates of the transport times that may be used in lieu of site-specific data);Vdp is the annual mass or volume of food medium p produced in subregion d, in kg or liters;V is the mass or volume of the food medium p produced annually with the 50-mile radius about the site, in kg or liters; andis the radiological decay constant for nuclide i, in days-The population served by all the food produced within 50 miles of the site is estimated as Pp = V /I U f (D-3)p .a ap a r where fa is the fraction of the population within the age group a;a P is the estimated population that can be served by the quantity of food p P likely to be produced within 50 miles of the site;Ua is the use or consumption factor of food medium p for the average individual Uap in age group a, in kg/yr or liters/yr (taken from Table E-4); and V is the annual mass or volume of food medium p likely to be produced within P a 50-mile radius about the site, in kg or liters.The annual population-integrated dose is then calculated as D 0.001 Y' P p f aC.i U apDF ai(D-4)Sp a where: P p if P*p < P 5 p 50 Pp ., P5 if Pp > P5" 50] 50*and DFai is the ingestion dose factor for age group a and nuclide i, in mrem/pCi (taken from Appendix E, Tables E-ll to E-14);1.109-31 TABLE D-1 RECOMMENDED

50 miles.All other factors are as defined above.Note that the above formulation limits theevaluation of the exposed population evaluation to the population residing within 50 miles as specified in paragraph D,Section II of Appendix I to 10 CFR Part 50. In calculating the annual population-integrated total body and thyroid doses, the age distribution of the population within 50 miles may be assumed to be the same as the age distribution of the U.S. population (Ref. 1). Reference

1 indicates the fractional breakdown to be as follows: children, 0.18; teenagers, 0.11; and adults, 0.71. Infants (0-1 year in age) are not projected to exceed 2% of the population (Ref. 1), and their population fraction has been included in that given above for children.2. Use of the Models a. Population-Integrated Doses from Liquid Effluents The annual total body and thyroid population-integrated doses due to exposure to liq-uid effluents should be evaluated for the following principal pathways:

potable' water, aquatic food products, external irradiation from shoreline deposits, and terrestrial food products irri-gated with water that has received the liquid effluent.(1) Doses from Potable Water The annual population-integrated total body and thyroid doses from water consump-tion are evaluated for all subregions that have water intakes existing or designated-at the time of the license application.

The products of the individual doses and the population exposed in each such subregion within 50 miles from the site are summed to obtain the total dose. The formulation expressed in Equation (D-1) may be used.The total body and thyroid dose of the individuals should be evaluated using-Equation (A-2) in Appendix A of this guide, together with the age-dependent usage factors U ap obtained from Table D-1 The dilution from the discharge point to the usage point'should be evaluated using appropriate hydrological models for the various subregions.

If the population served by a particular water supply. system is not known, it can be estimated by the following:

Pw e v/c (D-5)where c is the average daily usage of individuals on the system, in gal/day per person;Pw is the estimated population served by the water system; and v is the average daily intake of the water supply system, in gal/day.If the industrial usage from the water supply system is known, it can be sub-tracted from the average daily intake of the system before this value is entered into Equation (D-5).The population served by a water supply system whose intake is within the 50-mile radius may include individuals who reside outside the circle. This population may be pro-rated to include only the population within the 50-mile radius. Conversely, a water supply system with an intake beyond the 50-mile radius may serve the population within the 50-mile radius, whose exposure via drinking water should be included in the 50-mile population dose evaluation.

1.109-33

(2) Doses from Aquatic Food Products The annual population-integrated total body and thyroid doses from consumption of aquatic food products are evaluated using the production of sport and commercial harvests in the various subregions.

The mixing ratio (or dilution)

should be evaluated for each subregion using an appropriate hydrological model. For sport harvests, the entire edible harvest is a'ssumed to be ingested by the population within 50 miles. The formulation expressed by Equation.(D-4) should be used with-the population Pp.given by the results of Equation (D-3). The age-specific ingestion rates of Table E-4 may be used in lieu of site-specific data.For commercial harvests, the production within 50 miles from the site is con-sidered as part of the total U.S. harvest. Equation (D-2) should be used to compute the average concentration, with V as the total estimated U.S. commercial harvest of the aquatic food p medium p. The annual population--integrated dose is then computed using Equation (D-4) with Pp = P 5 0.The age-specific factors of Table E-4 may be used in lieu of site-specific data.(3) Doses from Shoreline Deposits The annual population-integrated total body and thyroid doses from recreational activities on the shoreline of the receiving water body are evaluated by summiing the product of the individual doses in each subregion and the population exposed therein. All subregions within the 50-mile radius should be considered.where existing or designated recreational facili-ties exist. If available, actual recreational usage in the vicinity of each facility should be used. The formulation of Equation (D-l) is appropriate.

(4) Doses from Consumption of Terrestrial- Food Products Irrigated by Waters Receiving the Liquid Effluent The annual population-integrated total body and thyroid doses from consumption of food irrigated with water from the body receiving the liquid effluent are evaluated following the procedures outlined in the development of Equation (D-4). Note that the term V of Equations (D-2) and (D-3) denotes the total production of food medium p within 50 miles, not just the total production of irrigated food medium p. The consumption rate data of Table D-l may be used in lieu of site-specific data in the evaluation of Equation (D-4).b. Population-Integrated Doses from Airborne Effluents The annual total body and thyroid population-integrated doses should-be evaluated for the following principal exposure pathways:

noble gas submersion, inhalation of airborne efflu-ents, ingestion of contaminated terrestrial foods (milk, meat, and produce), and external irradiation from activity deposited on the ground. Available state or county agricultural pro-duction data may be used for estimating the population-integrated doses from food consumption.

For the evaluation of exposures from atmospheric releases, the 50-mile region should be divided into 160 subregions formed by sectors centered on the 16 compass points (N, NNE, NE, etc.) and annuli at distances of 1, 2, 3; 4, 5, 10, 20, 30, 40, and 50 miles from the center of the facility.

The atmospheric dispersion factors (x/Q) or similar factors should be evaluated at the radial midpoint for each of the subregions using appropriate atmospheric dispersion models such as those described in Regulatory Guide 1.111.(1) Doses due to Exposure to Noble Gases The annual population-integrated total body dose due to noble gas effluents should be evaluated by summing the products of the individual doses in each subregion and the population in each subregion.

Equation (D-1) may be used. For external exposure, the model does not differentiate between age groups. A structural shielding factor of 0.5 should be applied in conjunction with the dose factor data of Table B-l.(2) Doses due to Inhalation of Radioiodines and Particulates The annual population-integrated total body and thyroid doses from inhalation of airborne effluents should be evaluated by summing the products of the individual doses received in each subregion and the population in each subregion.

Equation (D-1) may be used. The age-specific inhalation rates of Table E-4 may be used with the data of Tables E-7 to E-l0.1.109-34

(3) Doses due to Ingestion of Terrestrial Food Products The annual population-integrated total body and thyroid doses from. ingestion of terrestrial food products should be evaluated using the production data for each subregion.

For milk, meat, and commercial vegetables, the formulation of Equation (D-2) should be used to calculate the average concentrations in the foods. These concentrations are then used in Equation (D-4), along with the data of Tables D-l, E-4, and E-ll to E-14, to calculate population doses.(4) Doses due to External Irradiation from Activity Deposited on the Ground The annual population-integrated total body and thyroid doses from external exposure to surface deposition of the effluent should be evaluated using Equation (D-l). A household shielding and occupancy factor of 0.5 should be applied in conjunction with the dose factors of Table E-

DATA FOR THE CALCULATION

OF ANNUAL DOSES TO MAN FROM ROUTINE RELEASES OF REACTOR EFFLUENTS This appendix contains data for use in the equations presented in the Regulatory Position and in Appendices A, B, C, and D of this guide. The numerical values presented in this appendix are those routinely used by the NRC staff. In instances where more appropriate information of a site-specific nature has been developed and documented, that information should be used.In a number of instances the staff has found it necessary to provide guidance as to the value of a particular parameter in the absence of substantial empirical data. In such instances the staff has exercised judgment and has considered values used by others and the sensitivity of the results to the value assumed.Information is provided below under four broad categories:

environmental data, human data, dose factors, and other parameters.

1. Environmental Data Table E-1 provides values for the following staDle element transfer coefficients:

a. Biv for the estimation of produce, leafy vegetable, or pasture grass radioactivity from that in soil (pCi/kg in vegetation per pCi/kg in soil);b. Fm for the estimation of cow milk activity from that in feed (pCi/i in milk per pCi/day ingested by the animal); and c. Ff for the estimation of meat activity from that in feed (pCi/kg in meat per pCi/day ingested by the animal).The data are largely derived from Reference

1. The value of the cow milk transfer coefficient for radioiodine is based on the staff's review of the literature (Refs. 2-9).Values of transfer coefficients for goat milk are presented in Table E-2 for a limited number of nuclides.

For nuclides not listed in Table E-2, the milk transfer coefficient from Table E-1 should be used.Various animal parameter values are presented in Table E-3 for use in estimating animal product activity levels as functions of the corresponding levels in feed and water supplies.2. Human Data Tables E-4 and E-5 present usage rates of various environmental media by average individuals and maximum individuals, respectively, according to age group. "Seafood" is used to indicate intake of aquatic invertebrates such as lobster, crab, clams, and'oysters.

Ingestion of aquatic plant material is not normally assumed.3. Dose Factors Dose factors for external irradiation from a uniformly contaminated ground plane are 2 presented in Table E-6 (Refs. 10 and 11), in units of mrem/hr per pCi/m .These factors are applicable for surface contamination via deposition of liquid effluents on shoreline sediments or airborne effluents on ground surfaces.

Dose factors are provided for the total body and skin only. Doses to other organs are assumed equal to the total body dose.Dose factors provided in Table E-6 are derived from a consideration of the dose rate to air 1 meter above the ground plane and the penetration of the radiation into the body. The total body dose is computed at a penetration depth of 5 cm; the skin dose is computed at a depth of 7 mg/cm 2.These tissue depths are indicated by Reference

m. Reference

12 also identifies the cells of the basal layer of epidermis as the tissue of interest 2 in the computation of skin dose and states an average depth for these cells of 7 mg/cm .This guidance is reflected in the dose factors presented in Table E-6 and also in those presented in Appendix B, Table B-l, for use in calculating external doses from noble gases.Dose factors for internal exposure are provided in Tables E-7 through E-14, in units of mrem per pCi intake (Ref. 25). Tables E-7 through E-l0 are for inhalation (one table for each of the four age groups), while Tables E-ll through E-14 are for ingestion.

Dose factors provided for the inhalation of H-3 include an increase of 50 percent to account for the additional amount of this isotope absorbed through the skin (Ref. 25).As discussed in Section B, "Discussion," these dose factors are appropriate for continuous intake over a one-year period and include the dose commitment over a 50-year period. The cal-culational scheme by which these dose factors are derived includes elementary consideration of changing physical and metabolic characteristics during the period over which the dose commitment is evaluated.

For example, environmental exposure of an infant over a one-year period is treated as follows: dose during the first year is computed based on infant physiological-and metabolic characteristics considering both the buildup and decay of the appropriate organ burden; dose durin

g. years

1-10 is computed based on child physiological and metabolic data considering decay.of the organ burden from its peak value at age 1; dose during years 11-16 is treated in a similar fashion using teenager characteristics;

and dose during adulthood is computed based on the physiological and metabolic characteristics of an adult. Age-dependent parameters are changed in steps at the breaks between age groups.4. Other Parameters.Table E-15 has been provided as a central location for the recommended values of many of the miscellaneous parameters appearing in equations in this guide. In some instances, a parameter's value or units is a function of the equation it is used in. Additionally, for some parameters used in calculating activities in vegetation, the value is also a function of the exposure path-way. Table E-15 has been organized to note these complications.

Values of the parameter SF, a structural shielding and occupancy factor, are given in Table E-15 as 0.7 (for maximum individuals)

and 0.5 (for the generalpopulation).

Using the general approach given in Reference

26, the staff estimates an average structural shielding factor of 0.5 for typical reactor effluents.

Assuming the maximum individual spends about 50 percent of the time indoors, the overall shielding and occupancy factor is then approximately

0.7. The factor of 0.5 is used directly for population dose calculations.

These factors are applicable for external gamma exposure from noble gases and for external exposure from contaminated ground surfaces.1.109-43 TABLE E-7 PASE I OF 3 INHALATION

THE I FUNCTION The NRC staff calculates ground-level gamma radiation doses from elevated noble gas releases using Equation (6) in Regulatory Posifion C.2.a of this guide. Equation (6) is based on the model presented in Slade (Ref. 1), which can be characterized as a vertically finite sector-averaged Gaussian plume model. Use of the model involves volume integration over a distributed source, resulting in certain integrals that define the I function, denoted by TT in Reference

1.1. Derivation of the I Function The derivation of the I function presented below is taken directly from Reference

1, which should be consulted for further details.The sector-average airborne radionuclide concentration resulting from a continuous release is given by the Gaussian plume model as (see Equation 7.60 of Ref. 1)::(Rz) Q exp 2(z -h + exp (F-i)2V~0 zURe 22L 2oL v~Taz uez where h is the effective release height, in meters;QD is the effective release rate, considering decay in transit, in Ci/sec;(7)1 R is the downwind distance, in meters;u is the average wind speed, in m/sec;x(R,z) is the sector-average concentration at location (R,z), in Ci/m3 z is the vertical distance above the ground plane, in meters;e is the sector width, in radians; and a o is the vertical plume spread, in meters.Equation (F-l) maybe restated, for simplicity, as: 7(R,z) = 'DG(z) (F-2)zRe where G(z)= expF- iz h)2 + exp (F-3)L 2a j L 2a J zp z where the terms are as defined above.6.1.109-72 M -77-ME ý" , :E ý -,

The gamma dose rate to air at a distance of r meters from a point source of q curies is expressed by (see Equation 7.33 of Ref. 1): Pa q(3.7xlOl10)E(l.6xlo

-6)B(p,jia r)exp(-or)

41r 2 (1293)(100) (F-4)Where B(,va ,r) is the buildup factor, dimensionless;

D' is the dose rate to air, in rad/sec;E is the gamma ray energy per disintegration, in MeV;q is the point source strength, in curies;r is the distance, in meters;P is the attenuation coefficient for air, in m-1l la is the energy absorption coefficient for air, in m-I 100 is the number of ergs per gram-rad;1293 is the density of air at standard temperature and pressure, in g/m3 1.6 x 10-6 is the number of ergs per MeV; and 3.7 x 1010 is the number of disintegrations, per Ci-sec.Equation (F-4) may be simplified as follows: S KiaqEB(P,'a,r)exp(-pr)

41Tr (F-5)M~ were K (3.7 x 10101(.6 x I0- 6 0.46 (1293)(100)=04 (F-6)The next step is to incorporate Equation (F-2) into Equation (F-5) to arrive at an ression for the differential dose rate dD' from the differential volume dV containing the e... nuclide concentration X(R,z). Consider a volume element of the plume located z meters above r ga...d and at a horizontal distance L meters from-receptor location (R, 0) (see Figure 7.20 0the All such volume elements located at the horizontal distance L are included in the 7, ,g91shaped differential volume 21TLdLdz.

If R is sufficiently large that the concentration r 0 aged over all such volume elements can be approximated by -(R,z), the contribution of the Vershaped differential volume dV to the air dose rate at location (R,0) is given as K ia EB( p' va'r)exp(-

• 1:1 I where q has been replaced by x(R,z)dV.

Substituting (L 2 + z2)I/2 for r and 2wLdLdz for dV in Equation (F-7), and integrating, the following expression is obtained: Ku Ia EQ D B [vi'vaý (L 2+ zI)j1 G(z) exp LuI(L 2+Z2 jLdd 2 ,/2'R7 L 2 + z 2 0 0 (F-8)The I function, denoted by T T in Reference l, is defined as B_1__(_2_

2. Evaluation of the I Function In Reference

1 the I and 12 integrals have been evaluated.

and the results presented graphically.

Extraction of the data from these six-cycle log-log multicurve plots is a formidable task. A more satisfactory approach is to prepare a tabulation of the integrals as evaluated using numerical methods. These data can then be interpolated in implementing Equation (6) of Regulatory Position C.2.a.The .NRC staff has developed a computer routine that evaluates the I function as formulated in Equation (F-g). The I function as expressed in Equation (F-9) is independent of the buildup factor form. A listing of this routine is provided in Figure F-1. Communication with the routine is through the COMMON statement, which also communicates with the function subprogram BULDUP, which defines the dose buildup factor B(p,p ar) desired by the user.Also, Yankee Atomic Electric Company has supplied a routine written by Dr. John N. Hamawi of that company (Ref. 2). This routine evaluates the I, and 12 integrals as formulated in Equations (F-14) and (F-15), respectively.

A li.sting of the routine is provided in Figure F-2 (reproduced with the permission of Yankee Atomic Electric Company).

With the exceptions of changes in the title, the addition of the COMMON statement, the computing of I from IlI and 12V and comment cards as to its authorship, the routine is reproduced as written by Dr. Hamawi. The staff has compared the two routines and found their results to be in excellent agreement.

The routine supplied by the Yankee Atomic Electric Company was found to be considerably faster than the staff's routine.1 .109-75 C**C C C, C .C C C.C C C C C C C C Cw SUBROUTINE
