Introduction and Snamary-In accordance'with the Unique Reporting Requirement of

. Technical Specification 6.9.2 applicable during the reporting period, this report summarized the radiation doses due to radioactive effluent releases from Peach Bottom Atomic Power-Station Units 2 and 3.for-the period January 1, 1988, through December 31, 1988.

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 Res"~. ting from PBAPS' Units 2 and 3 with 10CFR50 Appendix I Dese,n Objectives.

Specifically, the maximum offsite dose due to liquid releases was 8.95-01 mrem; the maximum dose due to gaseous releases was 2.20-02 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 1

Nuclear Power Operation", limits.

This report is assembled in two parts:

Part 1 is for liquid and gaseous dose calculations; Part 2 is for meteorological data.

Ic INTRODUCTION f

I I

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 reactor is described in the Updated Final Safety Analysis Report II.

Couowingo 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.

PEACH BOTTOM LIQUID AND GASEOUS RADWASTE EFFLUENT I

II.

The liquid radwaste system at Peach Bottom is a common I

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 I

described in detail in the PBAPS UFSAR g aste system is appropriate to that type.

The liquid r Liquid wastes are processed on a batch basis and each batch is sampled prior to release.

The processed liquid wastes may I

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 I

plant circulating water prior to release into Conowingo Pond through a submerged jet-type discharge structure.

I 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 I

a single release point.

The physical characteristics which apply to each of the Station's release points were detailed in the 10CFRSO, Agpendix I Radioactive Effluent Dose Assessment Report The release of radioactive materials in liquid and gaseous I

effluents from Peach Bottom were reported in the Peach ReportsNos.25and26LgionN.mi-Annual Effluent Release Bottom Atomic Power Stq ce 6

Due to the long term shutdown at PBAPS, there were no reported iodine releases I

and all fission gases were listed as unidentified.

For the purposes of this report, all unidentified fission gases are assumed to be Kr-85.

i-I III. HYDROLOGY AND METEOROLOGY A.

Hydrology I

The Peach Bottom site is located on Conowingo Pond formed in the Susquehanna River by the Co3owingo Dam.

The flows J

of the Susquehanna River are unrega?ated except for the I

influences of the three run-of-the-river hydroelectric plants and one pumped storage hydroelectric plant upstream of Units 2 and 3.

The average riv

) flow at the plant site is 36,200 cubic feet per second The liquid radwaste from Peach Bottom Units 2 and 3 is I

discharged into a discharge canal where it is mixed with the station circulating water discharge.

After release of the diluted liquid radwaste from the Peach Bottom discharge canal, the concentration of radioactivity in I

the Pond continues to decrease by several mechanisms, including radioactive decay and mixing of the discharged water with additional Pond water.

At times, operation of the Muddy Run pumped storage hydroelectric plant also affects the mixing characteristics of Conowingo Pond by reversing the normal downsteam flow during the pumping I

cycle.

This only occurs when natural river flows are below about 13,000 cfs.

In order to estimate dilution of liquid radwaste by Pond I

water, an extensive series of tests were run under the supervision of Dr.

D.

W. Pritchard, Director of the Chesapeake Bay Institute of the Johns Hopkins University, I

utilizing the hydraulic model of Conowingo Pond located at the Alden Research Laboratories of Worcester Polytechnic Institute.

A description of these sts and selected data are provided in the PBAPS UFSAR I Since travei times and dilution factors applicable to the receptor locations of interest vary with Pond flow, the I

Pond flows were reviewed on a daily basis to determine a mean monthly Pond flow.

Each daily flov value was assigned to one of the three Pond flow regimes (see Table I

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 I

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 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 I

1-2

m discharge was assumed to be recycled to the. station water intake when flows are less than 15,000 cfs.

For river flows above 15,000 cfs, recirculation is not expected to occur.

In 1988, recirculation occurred only in June, July, August, September, and October.

The travel times and dilution factors for those locations in Conowingo Pond, where the high doses were calculated, are listed in Table III-2 for each monthly flow regime and were estimated using the test data presented in the Pggch Bottom Updated Final Safety Analysis Report I 1 The location numbers are those shown on Figure V-1.

B.

Meteorology Part 2 describes in detail the meteorology in the Peach Bottom Region di. ring 1988 affecting the atmospheric dispersion and the deposition of radionuclides from PBAPS gaseous radwaste releases.

This meteorology was used for the evaluation of Peach Bottom Units 2 and 3 gaseous releases.

IV.

LIQUID AND GASEOUS PATHWAY DOSE MODELS The maximum annual doses to individuals in unrestricted areas which could result from the effluent releases from Peach Bottom Atomic Power Station were calculated g ording to the guidelines in USNRC Regulatory Guide 1.109 and the models described therein.

Computer codes, LADTAP, and GASPAR, which incorporate the computational models

)

described in Regulatory Guide 1.109 and which were obtained from the NRC staff were used to perform the liquid and gaseous dose calculations respectively.

l 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 thebasesfortheseequatiggyhavebeendiscussedindetail in Regulatory Guide 1.109 3

Dose calculations for swimming and boating were not discussed in the guide, but total body doses from.hese pathways were calculated using the equations and dose factors provided in the LADTAP f

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

To account for 1-4

m m,

I reconcentration in June, July, August, September, and i

October the external reconcentration model in LADTAP was used in conjunction with equation:

- IU RECONi =1 + (RF *exp c)

Where:

I l

RECONi is the reconcentration factor for nuclide 1, unitless;

^

RF is the fraction of the discharged liquid that is recycled through the station (1/ dilution factor at point of intake) 0.45; 7 i is the radioactive decay constant of nuclide 1, in hr-1; I

tc river back to the station and through the station to the discharge point, 50 hours5.787037e-4 days 0.0139 hours 8.267196e-5 weeks 1.9025e-5 months .

For all other months RECONi equals 1.0 for all nuclides.

I 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 at each location to arrive at the total annual doses listed in Section VI.

The gasecus release pathways which were considered included external radiation from the air and ground, inhalation, and I

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 I

calculated for each pathway were to the total body, GI-tract, bone, liver, kidney, thyroid, lung, and skin.

I 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 g

building vents.

The equations, source term, and meteorology 3

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.

RECEPTOR LOCATIONS AND USAGE FACTORS FOR ANNUAL DOSE EVALUATIONS I

A.

Liquid Releases The annual doses resulting from PBAPS liquid radwaste l

lg releases were calculated at various locations on Conowingo E

P nd.

The cati ns 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. I which is 1500 ft. downflow from the PFA S Discharge Canal exit represents a worst case location M*ere a significant amount of fishing from a boat may ocet.;

Therefore, at this location doses from eating fish and boating were evaluated.

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

l where a significant amount of Conowingo Pond recreational

- uses'may occur.

Therefore, at this location the doses resulting from eating fish, swimming, boating,-and shoreline L

rdereation were calculated.

)

Doses resulting from drinking-water were calculated at drinking water supply intakes for Chester Water Authority (Location 2), and Conowingo Dam (Location 4) located on Conowingo Pond.' The City of Baltimore (Location 5) withdrew drinking water from Conowingo Pond at an average of 3.4 days-l per month throughout 1988.

However,_since Conowingo Pond represents only a small' fraction of the water supply for the City of Baltimore, any doses resulting from this pathway are much smaller'than those estimated from drinking water at Conowingo Dam.

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 liquid radwaste relearas are listed in Table V-l 1.

The basis of each is also listed.

Only fish consumption I

was considered for the aquatic foods pathways in'the Peach

- egion.

In accordance with Regulatory Guide

~

- Bottoy9[1, 1.109 a shore width factor of 0.2 was utilized for shoreline recreation.

There is no known use of water from Conowingo Pond for crop irrigation; therefore, this pathway L

was not included.

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

B.

Gaseous Releases i

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

The locations of real receptors which were evaluated ir

.i s study were determined by an extensive field survey during 1976 in the area within five miles of the release points.

The survey was updated by a dairy pasture survey in 1988 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/O 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 1-6

consumption, cow-milk, and meat pathways.

CALCULATED ANNUAL DOSES A.

Liquid Releases 1

Table VI-1 through VI-4 list the calculated annual doses through the various pathways to the maximum individual in i

the adult, teenager, child, and infant age categories as a l

result of Peach Bottcm liquid radwaste releases.

All l

locations having maximum estimated doses to any organ by any j

pathway or by all pathways have been included.

The maximum 1

doses calculated' vary between the adult, teenager, and child categories.

The following discussion, therefore, pertains I

to the maximum individual in each case.

j i

The location with the highest total dose to any organ and to

{

the total body is 1500 ft. downstream of the Discharge Canal i

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 critical organ is liver.

3 The location with the highest calculated doses to any organ for the shoreline recreation and swimming pathways is Location 3, Glen Cove.

The doses from these two pathways, 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 1.1 percent of the maximum organ dose at Location 1.

I B.

Gaseous Releases

)

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, skin, and organ dose resulting from exposure to noble gases, particulate 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 8.40E-03 mrem /yr. to the total body, 1.4SE-02 mrem /yr. to the skin,and 1.97E-02 mrem /yr. to the j

bone.

The primary exposure pathway is vegetation, for total l

body and bone and plume for skin.

j i

l-7

I The location where a real person would receive the largest calculated total body dose from exposure to noble gases and particulate released from PBAFS 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 calcuhted to be 1.32E-03 mrem /yr. to the total body.

The calculated skin dose at this location is 5.19E-03 I

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) would result in an insignificant dose.

VI.

CONCLUSION Table I-I, Introduction and Summary, summarized the maximum calculated annual doses resulting from Peach Bottom Units 2 I

and 3 routine liquid and atmospheric radwaste releases and how they compare to the 10CFR50 Appendix I design objective dose limits.

The maximum calculated total body dose resulting from Peach Bottom Units 2 and 3 routine liquid radwaste releases during I

1988 was 6.24E-01 mrem /yr. and occurred at Location 1, 1500 downstream from the Peach gttom Discharge Canal exit.

ft.

USNRC Regulatory Guide 1.109 I

, Table 1 lists the 10CPRSO, 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 10.4% of this design objective.

The maximum calculated dose to any organ resulting from Peach Bottom Units 2 and 3 routine liquid radwaste releases was 8.95E-01 mrem /yr. to liver and also occurred at Location 1.

The Appendix I design objective for dose to any organ (59m a Pathways as listed in USNRC Regulatory Guide 1.109 f

> is 10 mrem /yr. per reactor.

The maximum calculated dose to any organ resultit.g f rom Peach Octtom liquid radwaste releases is 4.5% of this design objective.

I The maximum calculated total body and skin doses occurring at occupied locations resulting from exposure to noble gases, particulate, and iodine released to the atmosphere by PBAPS were 8.40E-03 and 1.4SE-02 mrem /yr. respectively.

I These values are very small fractions of the 10CFRSO 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 1.97E-02 mrem /yr. to a child's bone due to all real pathways at that location.

As indicated in Table 1-1, Introduction and Summary, this maximum dose is a small fraction of the design objective dose limits of 10CFRSO Appendix I listed.
