Page 3 I;1TRODUCTIOH This manual provides the methodology to calculate radiation dose, to individuals in the vicinity or the St. i.ucie s't, fro . radio-act've gaseous and l'quid ef="uents. It also provides methocology for calcu'ating e"fluent monitor setponts and al'owable release rates to ensure compliance with the STS and 10C:R20 release cr'itera.

The 'n-plant procedures specify what sections of the ODCN shoula be completed to calculate the dose to an individual.

The ODC1 :ollows, the methodolooy and models suggested by NlcZG-0133 (iNov 1978) and Regulato y Guide 1.109. Simplifying assumptions.

have been applied where applicable to provide a more workable document for implementing the Technical Spec'='cation requi.rements.

Alternate calculation methods may be used from.those presented as long as the overal'ethodology does not change or as long as the alt rnative methods provide results that are more limiting.

Also, as available, the most up-to-date revision of th ..egulatory Guide 1.109 cose corversion factors and environmental t-.ansfer factors may be subst'tuted for those currently included and used in this document.

The St. Luc.'e Plant is located on an 'sland surrounded on cwo s'des by the Atlantic Ocean -,and the ind"'an River, an estuary of the A.tlant'c Ocean. Nornally, all rad'oact've liqu d re- .

No .cred't 's tzken for subsequent m'zing or che discharge f"ume with che ocean. he ci==nsion of radioaccive macerial into the ocean 's dependent on the cond'ions of, tide, wind, znd some eddy c rrents caused by the Gulf Stream.

There are no direct discharge pa.chs for liqu d ef luents to e.'ther of the north or south p ivate proper"y boundary lines.

The Big Mud Creek (part of the indian R've ) does connect to a norm"lly locked shut dam, that is intended to provide an emergency supply of circulating water to che intake Cooling

Ho radioactive ware could be d scharged di-rectly into the intake Cooling Mater Canal because all p'anc piping is routed to the discharge canal and no back flow can occ ".

As discussed 'n Section 2.5, the grass-cow/goat-milk pathway has been identified as the most imiting pathway with the

'nfant's thyroid being the czcal ozgan. Th's pathway typical' contributes greater than 90lo of,6 tcrtal dose contri-received by the infant's thyroid and the radioiodine bute essentially all ox this dose. There oze, ' is possible to demonstrate compl'ance with the dose limit of Technical Specification 3.11.2.3 for radioiodnes and particulates by only evaluating the 'nfant's thyroid dose due to the release of radioiodines v'a the grass-cow/goat-mi'k path~ay. The ca'culation method, of Section 2.6.3 is used for this deter-mination. The dose determined by Section 2.6.3 should be divided by a conservatism factor of 0.8. This added conservatism provides assurance that the dose determined by this limited analysis approach will be less than the dose that wou'd be determined by eva'uating all radionuclides anc all pathways. If this 1~ted analysis approach is used, the dose calculations for othez radioactive particulate matter and other pathways need not be performed.

Page 83 APPENDIX 2 Limited Analysis Dose Assessment for Liquid Radioactive "= '= 1uents The radioact've liquid effluents for the years 1978> 1979, and 1980 were evaluated to determine the dose contr "out=on or tne radionucl'de distr.'bution. This analysis was performed to evaluate the use of a limited dose analysis fo determining environmental doses. Lim ting the dose calculation to a few selected radionucl'des that contr'bute the majority of the dose provides a simplified method oz determ'ning compl'ance with the dose Limits of Technic 1 Specification 3.11.1.2.

Tables B-l and 8-2 present the results oz this eva'u? tion.

Table B-l presents the fraction oz the adult total body dose co..t".'buted by the major radionuclides. Table S-2 presents the same data =or the Adult GI-LLI dose. The acult total bocy and adult GI-LLI were determined to be the limiting doses based on an evaluation oz all (adult, teenager> ch ld> and 'nf nt) and all organs (oone>

age groups live"., kidney> 1> ng> and GI-LLI). As "he d? ta. in the tables show, the

?d o luclides "e-59 >

Co-58, Co-60, Zn-65, Cs-13<> and Cs -137 dom 'ate the ".otal body dose; the radionucl> des, ":e-59, Co-58, Co-60, Zn-65> and

>Nb-95 dominate the GI-LLI dose. In al'ut one case (1979 zish>

GI-LLI dose) these "adionuclides cont= bute 90'. or .ore of the total dose. If for 1979 the fish and shell= sh pathways are comoined as is done to determine the total dose> the cont=ibut'on from these nucl'des is 847. of the total GI-LLI dose.

There ore, the dose commitment cue to radioactive mate".'al liquid e==luents can be reasonably est.'mated by limiting he dose calculation to the r dionucl'des, ""e-59, Co-58, Co'-60, Zn-65>>lb-95>

+age R5 A2PZNDlX C Technical 3ases for .==ective Dose ".ac=ors Overview The eva'uat'on oz .doses due to'eleases o= radioactive material to the atmospher can be simplif ed by the use oz eff c 've dose transfer factors instead of using dose factors which are rad'anuclide specif'c. These effective factors> which a e,based on "he typical rad'onuc'de dis ribution in .the releases> can be applied to the total radioactiv.'ty released to approximate the dose in the environment, ie, instead og having to sum the isotopic distr bution multiplied by the isotope specific dose factor only a single rad=oactive mate

'ff mult'plicat'on (K f, M efff or efz ) times the total qua..tity oz ial iM

.eleased) would be ne dec. Th's approach provides a reasonable estimate of the actual dose wh'le eliminating the need for a detailed calculat'onal technique.

Determination of Effective Dose Factors The e =ective dose transfer zactors are based on pas- ooe a" ing, ~

data. The radioact've e zluent dist=ibution for the past yea".s -"can be used to derive single e>> ective factors bv the fo 1 lowing equa ions.

Th's added conserv tism provides addit'onal assurance tha" the evaluat'on oz doses by the use of a. single ef ective z ctor w.'ll not significantly underest =ato any actual doses in the environment.

Reeval a"ion The doses due to the gaseous e luents are evaluat d by the more detailed calculation methods (ie, use of nuclide spec.'f"c dose factors) on a yearly bases. At this time a comoarison can be made between the simpl:fied method and the detailed method to assure the ove all reasonableness of this limited analysis approach. lf this comoarison indicates that the radionuclide distribution has changed s'gni.ficantly causing the simplified method to underestimate the doses by more than 207.i the value of the ef ect've factors will need to be reex mined to assure the overall acceptab'l=ty oz this approach. However, this reexamination will only be needed 'f the doses as calculated by the de "iled analysis exceec 50"'. of the desig>-

bases doses ( ie, greater than 5 mrads gamm air dose or 10 mrads-.

beta air dose).

En any case, the appropriateness of the A value will be periodically evaluated to assume the applicability o a singl e- oc"'ve dose factor. =or evaluating environmental doses.

By assuming a typical rad'onuciide d'st"'but'on an equivalen" Xe-133 invento~ can be determined. Table D-l prov.'des the typical radionuclide (noble gases) dist 'but'cn and the Xe-133 equivalent concentrat'on. The equivalent concentrarion is determined by multiplying the radionuclide concentrat on by ehe ratio of the nuclide total 'oody dose actor to the Xe-133 tata'ody dose factor.

Summing a'1 the ind.'vidual radionuclide equ-valent concentrations provides the overall reactor coolant Xe-'33 equivalent concentrat.on.

The data show that the equ valent conco. =ation s a factor o 2 larger than the gross concentration (ie, 24 'Ci/gm total versus 47 Ci/gm equivalent. The resulting Xe-133 eq" ivalent curie inventory of the reactor coolant system is aporox'mately 86,000 C'.
