Introduction and Summary In accordance with-the Unique Reporting Requirement of-Technical Specification 6.9.2 applicable during the l

reporting period, this-report summarized the radiation doses l

due to radioactive effluent releases from Peach Bottom Atomic Power Station Units 2 and-3.forLthe period January l~,

1989, through'DecemberE31,.1989.

The' radiation doses due to the release of. radioactive materials during.the reporting period were within 10CFR50 Appendix I limits and'.'within'40CFR190 limits as indicated on Table I-1, Comparison of Doses Resulting from PBAPS Units 2-f and 3 with 10CFR50 Appendix I Design. Objectives.

l Specifically, the maximum offsite dose due to liquid l

l releases was'2.84-01' mrem; the maximum dose.due to gaseous l

releases was 4.18-02 mrem.

Since PBAPS releases were'well within applicable radioactive-effluent technical-specifications limits and were a small-fraction of 10CFR50 Appendix I' design objectives, it is concluded that PBAPS-releases.were a:small fraction of 40CFR190, " Environmental Radiation Protection-Standards for Nuclear Power Operation", limits.

. INTRODUCTION Peach Bottom Atomic-Power Station (PBAPS) is located on the western shore of Conowingo Pond in York County, Pennsylvania.

The station, two 3293 MWT boiling water Reportyg)isdescribedintheUpdatedFinalSafetyAnalysis reactor Conowingo Pond is the receiving stream for liquid radwaste effluents.

Information pertaining to the liquid and gaseous radwaste source terms, hydrology, meteorology, dose models, and receptor locations along with the resultant doses due to the operation of Peach Bottom is-provided.

II.

PEACH BOTTOM LIQUID AND GASEOUS RADWASTE EFFLUENT The liquid radwaste system at Peach Bottom is a. common system shared by both reactor units.- The system is designed to collect various types of liquid wastes-separately so that each type of waste can be processed by those methods'most.

describedindetailinthePBAPSUFSARtgpastesystemis appropriate to that type.

.The liquid r9

.i.

Liquid wastes are processed on a batch basis and each batch is.

sampled prior-to release.

The processed liquid wastes may be returned to the condensate system for plant reuse or discharged to the environs.

The liquid to be-discharged is released into a discharge canal where it.is mixed with the plant circulating water prior to release into Conowingo Pond L

through a submerged jet-type discharge structure.

1 Gaseous effluents are released from Peach Bottom through three release points:

(1) the off-gas stack, (2)'the Unit 2 roof vent, and (3) the Unit 3 roof 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, Agpendix I Radioactive Effluent' Dose Assessment Report The release of radioactive materials in liquid and gaseous.

effluents from Peach Bottom were reported in the Peach BottomAtomicPowerStgionSemi-AnnualEffluentRelease 3' 5),

III. HYDROLOGY AND METEOROLOGY

{

l A. Hydrology

..)

The Peach Bottom site is located: on _Conowingo Pond formed in the Susquehanna River by the.Conowingo Dam. -The flows of the Susquehanna River are-unregulated except for the influences of the three-run-of-the-river hydroelectric i

l plants and-one pumped _ storage' hydroelectric' plant j

upstream of Units 2 and 3.'

The average riv plantsiteis36,200cubicfeet.persecondyg)flowatthe

- The' liquid radwaste f rom Peach - Bottom: Units 2 andf 3 is I

discharged inte a discharge canal-where it is mixed with l

the'stationicirculating water discharge.- After release 4

of'the_ diluted liquid radwaste from the Peach Bottom

(

discharge canal,_the"concentrationnof radioactivity in the Pond continues'to decrease by'severa1' mechanisms, including radioactive decay and mixing _of the discharged water with additional' Pond: water. - At1 times,.. operation of:

the Muddy Run_ pumped storage hydroelectric plant also.

i affects the mixing' characteristics'of Conowingo Pond by reversing the normal downstream flow during the pumping cycle.

This only occurs when natural river flows are l

below about 13,000 cfs.

t In order to estimate dilution of liquid radwaste by Pond water, an extensive series.of tests were-run under-thei supervision of Dr. D. W. Pritchard, Director of:the Chesapeake Bay Institute of the Johns Hopkins University, utilizing the hydraulic model of Conowingo Pond located at the Alden Research Laboratories of Worcester-Polytechnic Institute.

Adescriptionofthesegysts'and selected data are provided in the PBAPS;UFSAR l Since travel times and dilution factors" applicable to the receptor locations of interest vary with Pond' flow, the Pond flows were reviewed on a daily basis to determine'a mean monthly Pond flow.

Each daily flow value'was.

assigned to one of the three Pond flow. regimes (see Table L

III-1).

The resulting daily travel times and dilution factors were then averaged to determine a monthly mean travel time and dilution factor for'each receptor location.

The flow regimes - less than 15,000 cfs; between.15,000 cfs and 35,000 cfs; and greater than 35,000 cfs '-- match an appropriate grouping of average dilution conditions

. measured in model tests.

The first flow regime ~(less than 15,000 cfs) is of particular importance because l

recirculation can only occur at.these. low natural river flows.

Based on the model dilution tests, the recycle time from plant discharge to plant intake was estimated to be 50 hours5.787037e-4 days 0.0139 hours 8.267196e-5 weeks 1.9025e-5 months , and 45 percent of the initial radwaste-1-2

discharge-was assumed-to be recycled to the station water l.

l intake.when flows are less than 15,000~cfs.

For1 river flows above 15,000_cfs, recirculation is not~

expected to occur.

In 1989,_recirculationioccurred only in August, September, October and December.

The travel times and dilution factors for.those locations ~

in Conowingo Pond, where:theshigh doses were calculated, are listed in Table III-2 for'each monthly; flow regime and were estimatedL using the test data presented in the-

The location numbers areLthose shown on Figure L

V-1.

B. Meteorology L

Part-2 describes in'detall'the meteorologyf-in the Peach L

Bottom Region during 1989 affecting the atmospheric L

dispersion and.the deposition of' radionuclides from PBAPS gaseous radwaste releases.

.This meteorology was used.for the evaluation of Peach Bottom Units 12 and 3: gaseous-releases.

IV.

LIQUID AND GASEOUS PATHWAY DOSE MODELS 1

t The maximum annual doses to individuals in unrestricted areas which could result from the effluent releases from Peach Bottom Atomic Power Station were calculated.qggording to the guidelines in USNRC Regulatory Guide.l.109 L 1 and the models described therein.. Computer codes,3 LADTAP, and GASPAR, which incorporate the computational models described in Regulatory Guide 1.109 and which were obtained 1

from.the NRC staff were used to perform the. liquid and gaseous dose calculations respectively.

The liquid release pathways which were considered ~in making these calculations included drinking water, aquatic. foods, shoreline usage,' swimming and boating.

The equations for drinking water,. aquatic foods, and shoreline exposure;and; the bases for these equat19 in~ Regulatory Guide.l.109 \\gg1have been-discussed in detail 4

1 Dose calculations for swimming,and boating were not discussed in'the guide, but total body doses from these pathways were calculated using the equations and dose factors provided in the LADTAP computer code.

The doses to individual organs were taken'to be the same as the total body doses.for swimming and boating.

Since Peach Bottom Atomic Power Station is located on Conowingo Pond, where recirculation of water occurs during i

periods of low natural river flow, reconcentration of radionuclides was considered.

To account for 1-3

9;

reconcentration in' August, September, October'and December _

'the external reconcentration ~model in LADTAP was used in

. conjunction _with equation:

l RECONi =1+

(RF *exp - ite) l Where:

RECONi is the reconcentration factor for nuclide 1, unitless; RF is the fraction.of the discharged liquid that is-I recycled through the station (1/ dilution factor at point of intake) 0.45; Ai is the radioactive decay. constant.of nuclide l',-in.'hr-1; e

i l

discharge point, 50 hours5.787037e-4 days 0.0139 hours 8.267196e-5 weeks 1.9025e-5 months .

3 For all other months RECONi equals:1.0 fortall nuclides.

The doses from liquid releases were calculated for each month at each receptor location; the doses for each month.

were then summed,for each pathway atLeach location to arrive I

at the total annual doses listed;in'Section VI.

l The gaseous release pathways which were considered included external radiation from the-air.and ground, inhalation, and ingestion of vegetation, meat, cow's milk, and goat's milk.

The inhalation.and ingestion pathways were evaluated for the adult, teenager,-child and infant groups.

The dose Jealculated for each pathway were to the total body, GI-tract, bone, liver, kidney, thyroid, lung,Eand skin.

The calculation of dose _for'all pathways at each receptor; location (see Section V) was done in two parts

'a dose component resulting from the off gas stack.and one_from.the building vents.

The equations, source term, and met'eorology which apply to each case were used to~ calculate:the. dose-resulting from each component.

These doses were then summed to yield a total dose for each pathway and organ.

V. RECEPTOR LOCATIONS AND USAGE-FACTORS FOR ANNUAL DOSE EVALUATIONS.

A.

Liquid Releases i

The annual doses resulting from PBAPS' liquid radwaste.

releases were calculated at Various locations'on-Conowingo Pond.

The locations are shown in Figure V-1.-

These were.

selected because they represent areas where the listed pathway activities are most likely to occur.. Location No. 1 L

which is 1500 ft, downflow from the PBAPS Discharge Canal exit represents a worst case location where a significant amount of fishing from a boat may occur.

Therefore, at this i

location doses from eating fish and boating were evaluated.

Location No. 3, Glen Cove represents a worst case location j

1-4

J where a significant_ amount offConowingo. Pond recreational uses may occur.

Therefore, at this location the doses resulting from eating fish, swimming', boating, and shoreline recreation'were calculated.-

L Doses resulting from drinking water were calculated'at drinking water supply > intakes.'for Chester Water Authority (Location 2), and Conowingo Dam (Location 4) located cx1 l'

- Conowingo Pond.

The City of Baltimore (Location 5) withdrew L

dr' inking water-from Conowingo Pond at an average of 1.6 days l

per month throughout'1989.

However, since Conowingo Pond

'l represents only a small fraction.of the water supply for the-City of Baltimore,-any: doses resulting from this_ pathway are I

L much smaller-than those estimated from-drinking water 1at

(

Conowingo Dam.

i The Conowingo Pond usage rates and. fish and water consumption rates which were used in the calculation of doses for various pathways-and locations resulting from Peach Bottom 11guld radwaste releases are listed:in= Table V-1.

The basis.of each is also listed._ Only fish consumption was considered for the aquatic foods pathways in_the Peach Bottom region.

In accordance with Regulatory Guide 1.109(9), a shore' width factor of 0.2 was'utilizedsfor.

shoreline recreation..There is no known use of water from l

Conowingo Pond for crop irrigation; therefore, this pathway-was not-included.

There are no known private residences using. Pond water for drinking purposes; therefore,.this pathway was not included, i

n.

Gaseous Releases In order to assure that the location of the; maximum off-site-annual dose to each pathway resulting from-PBAPS radioactive i

gaseous effluents was identified, annual doses at several locations-were calculated.

These included real locations of dairy pastures,.and residences in each' sector.- Meat animal pastures were. assumed to co-exist with dairy pastures.

There was one herd of milk goats within five: miles of PBAPS.

4 L

The locations of.real receptors which were evaluated!in this-study were determined by anLextensive field. survey,during 1976 in the-area within five miles of-the? release points.

The survey was updated by a dairy pasture survey in 1989-which determined the pasture closest to PBAPS in each sector.

Doses were calculated at residence locations in the external radiation, inhalation, and_ vegetation consumption pathways.

These locations included the residences with the highest annual X/Q values.

In addition, dairy farms'were evaluated by assuming a farm residence existed at the same-location as the dairy pasture.

In-this case, the doses were calculated t

VI.

CALCULATED ANNUAL DOSES A.

Liquid Releases Table VI-l through VI-4 list the calculated annual doses through the various pathways to the maximum individual in the adult, teenager, child, and infant. age categories as a result of Peach Bottom liquid radwaste' releases.. All locations having maximum estimated. doses to any organ by any pathway or by all pathways have been included.

The maximum doses calculated vary between the adult, teenager, and child t

categories.

The following discussion, therefore, pertains to the maximum individual in.each case.

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 from eating fish, where the criticalEorgan is-liver.

The location with the highest calculated doses to any organ for the shoreline recreation and swimming pathways is l

Location 3, Glen Cove.

The doses from these two-pathways, L

however, are a small fraction-of the dose resulting from eating fish at this location and.do not significantly contribute to the total dose.

l Location 4, Conowingo Dam, is the. location with the highest calculated dose to any organ for the drinking water pathway.

The dose from this pathway, however, is only 1.3 percent of the maximum organ dose at Location 1.

s l

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 total body, and' organ dose resulting from exposure to noble gases, particulates and iodine released from PBAPS.

This is a residence located about 3800 feet SSE of the PBAPS building vents.

This dose-was calculated to the 1.05E-02 mrem /yr. to the total body, and 4.18E-02 mrem /yr. to the bone.

The primary exposure pathway is vegetation for total body and bone.

The location where a person would receive the largest calculated skin 1-6 l

1

' dose is a resid'ence located-about.14,800 feet southwest of the'PBAPS building vents.

This dose is calculated to be 4.20E-03 mrem /yr.

The location where.a real person would receive the largest calculated total-body dose from exposure to noble gases and particulates released f rom PBAPS due to: non-occupational-activities inside of.the site boundary is at the boat ramp approximately 3300 feet NNW of the PBAPs building vents.

This dose is calculated to be 3.63E-04. mrem /yr. to the total' t

body.

The calculated skin dose at'this location is 4.44E-04 mrem /yr. assuming continuous occupancy.

Assuming-the shoreline recreational usage factor (325 hours0.00376 days 0.0903 hours 5.373677e-4 weeks 1.236625e-4 months 'per year) l would result in an insignificant dose.

VII. CONCLUSION Table I-I, Introduction and Summary, summarized the maximum calculated annual doses resulting-from-Peach Bottom Units 2 and 3 routine liquid and atmospheric radwaste reJeases and how they compare to the 10CPR50 Appendix I' design objective dose limits.

The maximum calculated total body dose resulting from Peach-Bottom Units 2 and 3 routine liquid radwarte releases during 1988..was 1.97E-01 mrem /yr. and occurred at Location 1, 1500 ft. downstreamfromthePeachgQttomDischargeCanalexit.

I 7,

Table 1 lists the USNRC Regulatory Guide 1.109 10CFR50, Appendix I, design objective'for dose to total body from all pathways as 3 mrem /yr. per reactor.

The maximum calculated total body-dose resulting from Peach Bottom liquid radwaste releases is 3.2% of.this design objective.

The maximum calculated dose to_any organ resulting from Peach Bottom Units 2.and 3 routine liquid.radwaste releases was 2.84E-01 mrem /yr. to liver and also-occurred at Location.

1.

The Appendix I design objective for dose to any organ

{ggmallpathwaysaslistedinUSNRCRegulatoryGuide1.109-J is 10 mrem /yr. per reactor.

The maximum calculated dose to any organ resulting from Peach Bottom liquid radwaste releases is 1.4% of this design' objective.

The maximum calculated total body and skin doses occurring at occupied locations.resulting from exposure to noble gases, particulates, and iodine released to the atmosphere by PBAPS were 1.05E-02 and 4.20E-03 mrem /yr. respectively.

These values are very small fractions of the 10CFR50 l

Appendix I design objective dose limits as shown in Table I-1, Introduction and Summary.

The maximum calculated total annual dose to any organ from all nuclides which occurs at any location off site was 4.18E-02 mrem /yr. to a child's bone due to all real pathways 1-7

at that location.

AsindicatedinTableI-1,.Introductkon and Summary, this maximum dose is a small fraction of the design objective dose' limits of 10CFR50 Appendix I listed.

j The maximum calculated total-body skin doses due.to non-L occupational on-site activities resulting from exposure to

' gaseous releases to the atmosphere by PBAPS were 3.63E-04' and 4.44E-04 mrem /yr. respectively.

The values are very small fractions of 10CFR50 Appendix-I dosing objective dose limits.

s It is concluded that the estimated radiation doses resulting

'i from the routine discharge of liquid and atmospheric.

releases from Peach Bottom Atomic Power Station are extremely low and well within the design objectives given in' i

10CFR50, Appendix I.
