L I. Introduction and Sunry L in accordance with the Unique Reporting Requirement of Technical Specification 6.9.2 applicable during the reporting period, this report sunnarizes the radiation doses due to radioactive effluent releases frcm Peach Bottcm Atcmic Power Station Units 2 and 3 for the period January 1, 1987 through Dececber 31, 1987.

I The radiation doses due to the release of radioactive materials during the reporting period wa e within 10CFR50 Appendix

limits and within 40CFR190 limits as Indicated on Table 1-1, Ccmparison of Doses Resulting frcm PSAPS Units 2 and 3 with 10CFR50 Appendix ! Design Objectives. Speelfically, the max!r:un I offsite dose due to liculd releases was 6.89E-01 mrem; the maximum dose due to gaseous releases was 1.39E-01 mrem.

Since PBAPS releases were well within appilcable radioactive effluent technical specifications limits and were a small fraction of 10CFR50 Appendix I design cb.lectives, it is concluded that PBAPS releases were a small fraction of 40CFR190, "Environmentti Radiation Protection Standards for Nuclear Pcwer Operation",

limits.

This report is assembled in two parts: Part 1 is for liquid and gaseous dose calculations; Part 2 is for tretcorological data.

11. PEACH BOTTCf4 L1001D Af D GASEOUS RADWASTE EFFLUEffT The Ilculd radaaste system at Peach Bottan is a comon system shared by both reactor units. The systan is designed to collect various types of Ilculd wastes separately so that each type of I waste can be processed by those rothods rest appropriate to that type. The liculd radwaste systen is described In detall In the PBAPS UFSAR .

Liculd wastes are processed on a batch basis and each batch is sarreled prior to release. The processed liculd wastes may be returned to the condensate system for plant reuse or discharged to the environs. The 11culd to be discharged is released into a discharge canal where it is mixed with the plant circulating water prior to release into Concwingo Pond through a subnerged jet-type discharge structure.

I Gasecus effluents are released fran Peach Botto, through three release points: (1) the off-gas stack, (2) the Unit 2 roof vent, and (3) the Unit 3 rcef vent. For the purposes of this evaluation, Units 2 and 3 roof vents are considered a single release point. The physical characteristics which apply to each of the Station's release points were detailed in the 10CFR50, Appendix ! Radioactive Effluent Dose Assesstrent Report 3 The release of radioactive materials In liculd and caseous ef fluents f ra, Peach Bottan were reported in the Peach Bottom Atcr91c Pcwer Station Semi-Annual Effluent Release Reports Nos. 23 and 24 .

A. Hydrology ll The Peach Bottcm site is located on Conavingo Pond formed in the Susquehanna River by the Conowingo Dam. The ficws of the Suscuehanna River are unregulated except for the influences of the three run-of-the-river hydroelectric plants and one pumed storage hydroelectric plant upstream of Units 2 and 3. The average river ficw at the plant site is 36,200 cubic feet per second .

The IIquid radwaste frcm Peach Bottcm Units 2 and 3 is discharged Into a discharge canal v.here it is mixed with the station circulating water discharge. After release of the diluted liculd radwaste frcn the Peach Bottcm discharge canal, the concentration of radioactivity in the Pond continues to decrease by several mechanisms, including radluactive decay and mixing of the discharged water with additional Pond water. At times, operation of the Muddy Run pumed storage hydroelectric plant also affects the mixing characteristics of Conovingo Pond by reversing the nornul downstream ficw during the puming cycle. This only occurs when natural river flows are belcw about 13,000 cfs.

1-3 I

l In order to estirnste dilution of Ilculd rachvaste by Pond water, an extensive series of tests wre rm under the supervision of Cr. D.

W. Pritchard, Director of the Chesapeake Bay Institute of the Johns Hopkins University, utill:Ing the hydraulle rnodel of Concwingo Pond located at the Alden Research Laboratories of Worcester Polytechnic p Inst i tut e. A description of these tests and selected data are provided in the PBAPS UFSAR .

Since travel tlrnes and dilution factors applicable to '.he receptor j locations of interest vary with Pond flow, the Pond flows w re reviewed on a dally basis to deterrnine a rnean rnonthly Pond floa.

Each daily ficw value was assigned to one of the three Pond ficw regirres (see Table 111-1). The resulting daily travel t!rnes and dilution factors were then averaged to deterrnine a nrnthly mean l travel tirne and dilution factor for each receptor location.

The ficw regirnes - less than 15,000 cfs; between 15,000 cfs and 35,000 cfs; and greater than 35,000 cfs - match an appropriate l

grouping of average dilution conditions rmasurad in tredel tests.

The first ficw regirne (less than 15,000 cfs) is of particular Irnportance because recirculation can only occur at these icw natural river flows. Based on the rnodel dilutlen tests, the recycle ttrne f rcm plant disebarge to plant intake was estiruted to be 50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br />, and 45 percent of the initial radwaste discharge was assuned to be recycled to tha station water intake when (1cws are less than 15,000 cfs.

For noble gas releases, X/Q values were corrected for radionucilde decay during the tlrm of transport frcm the off-gas stack to the receptor 1ccation. This was done on an isotope by isotope basis I as described in Section IV. Tcie tirre of transport to the receptor f

location was calculated using average wind speeds for each sector bearing and the distance of receptor locations frcm the source.

The mcxtrrum annual doses to individuals in unrestricted areas which could result frcn the liquld effluent releases frcm Peach Bottcm Atonic l Pcwer Station were calculated according to the guidel:aes !n USNRC

)

Regulatory Guide 1.109 anc( the rrodels described therein. Computer codes, LADTAP, and GASPAR, which incorporate the ccmputatlonal nt>dels described in Regulatory Guide 1.109 and which were obtained frcm the NRC staff were used to perform the liquid and gaseous dose calculations respectively. For noble gas releases, GASPAR was rrodified to perform dose calculations according to the models described belcw. For lodine and particulate releases, GASPAR was used without nt>dification.

E The liquid release pathways which were considered in making these calculations included drinking water, aquatic focds, shoreline usage, swinming and beating. The equations for drinking water, aquatic fceds, and shoreline exposure and the bases for these equations have been discussed in detall in Regulatroy Guide 1.109 . Dose calculations for swirrming and boating were not discussed in the guide, but total body doses frcm these pathways were calculated using the equations and dose factors provided in the t.ADTAP ccmputer code. The doses to individual organs were taken to be the same as the total body doses for swirrming and boating.

I 1 - 10 I

e Since Peach Bottcm Atcmic Power Station is located on Conowingo Pond, where recirculation of water occurs during periods of Icw natural river flow, reconcentration of radionuclides was considered. To account for reconcentration in Jtne, July, and August the external reconcentration model in LADTAP was used in conjunction with equation:

RECCti,= 1 + (RF "exp c)

Where:

RECON g is the reconcentraticn factor for nuclide I, unitiess; y

I RF is the frar; tion of the discharged 11 auld that is recycled through the station (1/d!1ution factor at h point of !ntake) 0.45; 3 is the radioactive decay constant of nuclide I, in br-1, bI f

t is the cycle time fecm the point of discharge to the l

For all other months RECON, ecuals 1.0 fer all nucildes.

The doses frcm IIquid releases were calculated for each month at each receptor locatlon; the doses for each month were then smmed for each pathway at each location to arrive at the total annual doses listed in Section VI.

I The gaseous relevse pathways which were considered included external radiation frcm the air and ground, inhalation, and Ingestion of vegtation, meat, ccw's milk, and goat's milk. The Inhalation and

! Ingestion pathways were evaluated for the adult, teenager, child, and Infant groups. The dose calculated for each pathway were to the total body, GI-tract, bone, liver, kidney, thyrold, lung and skin.

I

l 1-l TFe calculation of dose for all pathways at each receptor 1ccation (see Section V) was done in two parts - a dose conponent resulting frcm the off-gas stack and one from the building l

vents. The equations, source term, and meterology which apply to each case were used to calculate the dose resulting from each N ccmpenent. These dcse were then sumed to yleid a total dose for each pathway and organ.

l The annual gama dose (mrad /yr) resulting frcm noble gases in l elevated plunes was calculated using a rrodified veriston of the RADOS ( ccmputer program called MARE ( . This program computes the sector average ganma dose in each of sixteen 22}

1 degree cerroass sectors on an annual basis. It assunes that the 1

radioactive plune is distributed uniformly across the width of f each 223 degree sector and is distributed in a Gaussian form in the vertical direction. The total dese at each receptor location l Is the sumation of the doses resulting frcm each Isotope which I

is transported and diffused by the same set of meteorological conditions frcm which X/Q values were derived, including terrain f heights, plume rises and vertical dispersion parameters.

Radioactive decay of the noble gases was taken into account during the time of transpcrt frcm the source to the receptor l

1ccation.

RECEPTOR LOCATI0t15 AIO USAGE FACTORS FOR #1NWL DOSE EVALUATIONS,

[ A. Liculd Releases l

The annual doses resulting frcm PBAPS 11guld radwaste releases f were calculated at various locations on Conowingo Pond. The locations are shavn in Figure V-1. These were selected because 1 they represent areas where the listed pathway activities are trost likely to occur. Location No. I which is 1500 ft. downficw from the PBAPS Discharge Canal exit represents a worst case location

! where a significant amount of fishing frcm a boat may occur.

Therefore, at this location doses frcm eating fish and boating were evaluated. Location No. 3, Glen Cove represents a worst case location where a significant ant >unt of Concwingo Pond recreational uses may occur. Therefore, at this location the doses resulting from eating fish, swinTning, boating and shoreline recreation were calculated.

I Doses resulting frcm drinking water were calculatea at drinking water supply intakes for Chester Water Authority (Location 2), and Conovingo Dam (Locatien 4) located on Concwingo Pond. The City of Baltincre (Locat ton 5? withdrew drinking water f rom Concwir.go Pond at an average of 4.3 days per month throughout 1987.

Mcwever, since Conowingo Pend represents only a small fraction of the wate.- supply for the City of Baltiricre, any doses resulting fecm this pathway are much smaller than those estimated frcm drinking water at Conowingo Octn.

l The Concwingo Pond usage rates and fish and water consumtion rates l

which were used in the calculation of doses for various pathways and locations resulting frcn Peach Bottcm IIquid radwaste releases are listed in Table V-1. The basis of each is also listed. Only fish consumtion was considered for the aquatic foods pathways in the Peach Bottcm region. In accordance with Regulatory Guide 1.109 , a shore l

width factor of 0.2 was utilized for shoreline recreattor. There is no kncwn use of water from Concwingo Pcnd for crop Irrigation; therefore, thia pathway was not included. There are no kncv.n private residences I using Pond water for drinkinc wrposes; therefore, this pathway was not included.

l B. Gaseous Releases E

l In order to assure that the location of the maximun off-site annual dose to each pathway resulting frcm PBAPS radioactive gaseous effluents was identified, annual doses at several locations were calculated. These included real locations of l

dairy pastures, and residences in each sector. Meat animal pastures were assuned to co-exist with dairy castures. There was one herd of milk goats within five miles of PBAPS.

l l The locations of real receptors VAlch vare evaluated in this i

study were determined by an extensive fleid survoy during 1976 in l

the area within five miles of the release ;;oints.

E l 1 - 14 5

l I

The survey was updated by a dairy pasture survey in 1987 which determined the pasture closest to PBAPS in each sector.

Doses v!a the cow-milk pathway and meat animal pathway determined at the center of dairy pastures were added to doses calculated at the farm residences for the external radiation, inhalation, and vegetation consuntion pathway.

The farm residence was assuned to be at the same location as the dairy pasture. Since the cc5+-milk-thyroid pathway is the critical pathway by a large margin (see Section VD, this approach assures that the location with greatest total dose f rcm all pathways has been evaluated.

I In addition to the fam residence locations, annual doses via the external radiation, Inhalation and vegetatlon consunotIon pathways were evaluated at several real residence locations. These locations included the residences with the highest annual X/O values.

VI. CALCULATED AttCAL DOSES i A. Liculd Releases I Table VI-1 through VI-4 list the calculated annual doses through the various pathways to the maxiram Individual in the adult, teenager, child, and Infant age categories as a result of Peach Bottcm liquid radwaste releases. All locations having maxinun estimated doses to any organ by any pathway or by all pathways have been included. The maxinun doses calculated vary between the adult, teenager, and child categories. The following discussion, therefore, pertains to the nuxinun Individual In each Case.

I The location with the highest total dose to any organ and to the total body is 1500 ft. downstream of the Discharge Canal exit (Location 1), where eating fish and boating are the potential pathways. The highest dose calculated to any organ results frcm eating fish, where the critical organ is liver.

The location with the highest calculated doses to any organ for the shoreline recreation and swirming pathways is location 3, Glen Cove. The doses f ecm these two pathvays, hcwever, are a small fraction of the dose resulting from eating fish at this location and do not significantly contribute to the total dose.

I 1 - 19 1

Location 4, Concwingo Dam, is the location with the highest calculated dose to any organ for the drinking water pathway. The dose frcm this I pathway, however, is only 4.3 percent of the maximtm organ dose at l

Location 1.

B. Gaseous Releases I Table VI-5 lists the annual doses to all organs through each pathway by age group at the location where a person would receive the largest calculated organ dose. The dose Is sun of the contributions frcm the two ccmponents; the off-gas stack and the building vents pitme. The largest dose contribution to any organ resulted from the cow-n11k-thyroid pathway at a dairy farm with the pasture located about 6600 feet SSW of the PBAPS building vents. The organ receiving the largest dose is the infant thyrold, which was calculated to receive a total of 1.39E-01 l mrem /yr. f rcm all real pathways listed in Table VI-5.

Approximately 97% of this total dose resulted from the ccw-mil k-thryold pathway, 2% fecm external exposure to noble gases,1% frcm Inhalation of air particulates and radiolodines, and less than 0.4% frcm exposure to activity deposited on the ground. No atterrot was made to determine the age of distribution of real residents. Therefore, the assurption that an infant exists at this locat ton could be very conservative.

Table VI-6 lists the arnual doses to all organs through each pathway by age group at the location where a person would receive the largest calculated total body dose resulting frcm exposure to noble gases, particulates and lodine released from PBAPS. This is a residence located about 3800 feet SSE g of the PBAPS building vents. This dose was calculated to be 1.51E-02 nrem/yr. to the total body. The location where a person would receive the largest calculated dose to the skin I resulting fecm exposure to noble gases, particulates and I

calculated total body dose frcm exposure to noble gases, particulates and lodine released frcm PBAPS due to non-occupatforal activities inside of the site boundary is at the boat rarro approximately 3300 feet NNW of the PBAPS building vents. This dose is calculated to be 6.51E-03 mrom/yr, to the total body. The calculated skin dose at this location is 1.91E-02 meem/yr. asstming cercinuous occupancy. Assuning the shoreline recreational usage factor I (325 hours0.00376 days <br />0.0903 hours <br />5.373677e-4 weeks <br />1.236625e-4 months <br /> per year) would result in an insignificant dose.

VII. CONCLUSION Table I-I, Introduction and Stmnary, smTnarizes the maxirun calculated annual doses resulting frcm Peach Bottcm Units 2 and 3 routine IIquid and attrospheric radwaste releases and how they ccmpare to the 10CFR50 Appendix ! design objective dose limits i

The maxirun calculated total body dose resulting frcm Peach Bottcm Units 2 and 3 routine 11guld radwaste releases during 1987 was I h.89E-01 mrem /yr. and occured at Location 1,1500 f t. dcwnstream frce t the Peach Bottcm Discharge Canal exit. USNRC Regulatory Guide 1.109 , Table 1 lists the 10CFR50, Appendix 1, design objective for dose to total body 'rcm all patbaays as 3 mrem /yr. per reactor. The maximtm calculated total body dose resulting frca Peach Bottcm 11guld radwaste releases is 8.2% of this design objective.

The maximtn calculated dose to any organ resulting from Peach Bottcm Units 2 and 3 routine liquid radwa;te releases was 6.89E-01 mrem /yr, to liver and also occured at Location 1. The Appa xfix I design cbjective for dose to any organ frcm all pathways as listed in USNRC Regulatory Guide 1.109 is 10 mrem /yr. por reactor.

The maximtm calculated dose to any organ resulting frcm Peach Bottcm liquid radwaste releases is 3. M of this design objective.

1 - 28 i

B

e The maximtm calculated total body and skin doses occurring at l

occupied locations resulting frcm exposure to noble gases, particulates, and lodine released to the attrosphere by PBAPS were 1.51E-02 and !+.27E-02 mrem /yr. respectively. These values are very small fractions of the 10CFR50 Appendix I design objective dose limits as shcwn in Table I-I, Introduction and Sunnary.

I The maximtm calculated total annual dose to any organ frcrn all nucildes which occurs at any location off site was 1.39E-01 mrem /yr. to an Infant's thyrold due to all real pathways at that location. The corresponding value resulting fecm only radiolodines and air particulates at this location was 1.31E-01 mrem /yr. to the Infant's thyrold.

I As Indicated in Table I-I, Introduction and Suvary, this maxirntm dose is a small fraction of the design objective dose limits of 10CFR50 Appendix I listed.

The traximtrn calculated total body and skin doses due to non-occupational on-site activities resulting frcm exposure to gaseous releases to the attrosphere by PBAPS were 6.51-03 and 1.91E-02 mrem /yr. respectively. the values are very small fractions of 10CFR50 Appendix ! desic;n cbjective dose limits.

1 - 29

It is concluded that the estirnated radiation doses resulting frcm the l

routine discharge of IIquid and atnespheric releases frcm Peach Bottcm Atcmic Pcwer Station are extremely Icw and well within the d 'gn objectives given in 10CFR50, Appendix I.
