Iritroduction and Surmary In accordance with the Unique Reporting Requirement of Technical

-Specification 6.9.2 applicable during the reporting period, this report surmarizes the radiation doses due to radioactive effluent releases from Peach Bottom Atomic Power Station Units 2 and 3 for the period January 1, 1986 through December 31, 1986.

The radiation doses due to the release of radioactive materials during the reporting period were within 10CFR50 Appendix I Ilmits and within 40CFR190 ilmits as indicated on Table I-1, Comparison of Doses Resulting from PBAPS Units 2 and 3 with 10CFR50 Appendix I Design Objectives. Specifically, the maximun offsite dose due to liquid releases was 4.35E-01 mrem; the maximun dose due to gaseous releases was 7.67E-01 m-em.

Since PBAPS releases were well within applicable radioactive effluent technical specifications ilmits 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",

ilmits.

This report is assenbled in two parts:

Part 1 is for 11guld and gaseous dose calculations; Part 2 is for meteorological data.

II. PEACH BOTTOM LICUID AND GASEOUS RADWASTE EFFLUENT The liquid radwaste systcm at Peach Bottom is a comnon system shared by both reactor units. The system is designed to collect various types of Ilquid wastes separately so that each type of waste can be processed by those methods nost appropriate to that type. The liquid radwaste systen is described in detail in the PBAPS UFSAR(

Liquid wastes are processed on a batch basis and each batch is sanpled prior to release. The processed IIquid wastes nay be returned to the condensate system for plant reuse or discharged to the environs. The IIquid to be discharged is released into a discharge canal where It is mixed with the plant circulating water prior to release into Conowingo Pond through a subnerged Jet-type discharge structure.

Gaseous effluents are released fran Peach Botton 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, Appendix I Radioactive Effluent Dose Assessment Report i

The release of radioactive materials in IIquid and gaseous i

effluents from Peach Botton were reported in the Peach Botton Atomic Power Station Semi-Annual Effluent Releases Reports Nos. 21 and 22( S 5),

III. HYDROLOGY AND METEOROLOGY A.

Hydrology The Peach Bottom site is located on Conowingo Pond fonned in the Susquehanna River by the Conowingo Dam. The flows of the Susquehanna River are tnregulated except for the influences of the three run-of-the-river hydroelectric plants and one pumped storage hydroelectric plant upstream of Units 2 and 3.

The average river flow at the plant site is 36,200 cubic feet per second The IIquid radwaste from Peach Bottom Units 2 and 3 is discharged into a discharge canal where it is mixed with the station circulating water discharge. After release of the diluted 11guld radwaste from the Peach Bottom discharge canal, the concentration of radioactivity in 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 punped storage hydroelectric plant also affects the mixing characteristics of Conowingo Pond by reversing the normal downstream flow during the purping cycle. This only occurs when natural river flows are below about 13,000 cfs.

i 1-3 i

In order to estimate dilution of 11guld radwaste by Pond 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, utilizing the hydraulic model of Conowingo Pond located at the Alden Research Laboratories of Worcester Polytechnic Institute. A description of these tests and selected data are provided in the PBAPS UFSAR Since travel times and dilution factors appilcable to the receptor locations of Interest vary with Pond flow, the Pond i

flows were reviewed on a daily basis to deterTnine a mean monthly Pond flow. Each daily flow value was assigned to one of the three Pond flow regimes (see Table 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 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 discharge was assuned to be recycled to the station water intake when flows are less than 15,000 cfs.

1-4

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

In 1986 recirculation occurred only in July, September, and October.

The trave'. times and dilution factors for those locations in Conowingo Pond where the highest doses were calculated are IIsted in Table III-2 for each monthly flow regime and were estimated using the test data presented in the Peach Bottom Updated Final Safety Analysis Report (

The location nurbers are those shown on Figure V-1.

B.

Meteorology Part 2 describes in detall the meteorology in the Peach Bottan Region during 1986 affecting the atmospheric dispersion and the deposition of radionuclides from PBAPS gaseous radwaste releases. This meteorology was used for the evaluation of Peach Botton Units 2 and 3 gaseous releases.

For noble gas releases, X/Q values were corrected for radionuc11de decay during the time of transport from the off-gas stack to the receptor location. This was done on an isotope by isotope basis as described in Section IV.

The time of transport to the receptor location was calculated using average wind speeds for each sector bearing and the distance of receptor locations from the source. The average wind speeds used for the off-gas stack and vent releases are ilsted in Table III-3 for each sector bearing.

1-5

The following equation was used to calculate the isotope by Isotope decay of noble gases during time of transport from the off-gas stack to the receptor location based on the average wind speed for that sector (see Table III-3).

LIQUID AND GASEOUS PATHWAY DOSE MODELS The maxinun annual doses to Individuals in unrestricted areas which could result frcm the radioactive effluent releases from Peach Bottom Atanic Power Station were calculated according to the guidelines in USNRC Regulatory Guide 1.109 and the models described therein. Computer codes, !_ADTAP and GASPAR, which incorporate the ccmputational models described in Regulatory Guide 1.109 and which were obtained from the NRC staff was used to perform the IIquid and gaseous dose calculations respectively.

For noble gas releases, GASPAR was modified to perform dose calculations acccrding to the models described below.

For lodine and particulate releases, GASPAR was used without modification.

The liquld release pathways which were considered in making these calculations included drinking water, aquatic foods, shoreline usage, swinming and boating. The equations for drinking water, aquatic foods, and shoreline exposure and the bases for these equations have been discussed in detail in Regulatory Guide 1.109 Dose calculations for swinming 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 ccmputer code. The doses to individual organs were taken to be the same as the total body doses for swinming and boating.

1 10

Since Peach Botton 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 reconcentration in July, September, and October the external reconcentration model in LADTAP was used in conjunction with the equation:

RECON,= 1 + (RF Mexp c)

Where:

RECON, is the reconcentration factor for nuclide I, unitiess; RF is the fraction of the discharged liquid that is recycled through the station (1/dllution factor at point of intake) 0.45; d

~

i is the radioactive decay constant of nuclide I, in hr ;

t is the cycle time fran the point of discharge to the c

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 RECON, equais 1.0 for all nuclides.

The doses from 11guld releases were calculated for each month at each receptor location; the doses for each month were then sunned for each pathway at each location to arrive at the total annual doses listed in Section VI.

The gaseous release pathways which were considered included external radiation fran 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 calculated for each pathway were to the total body, GI-tract, bone, liver, kidney, thyroid, lung and skin.

1-11

The calculation of dose for all pathways at each receptor location (see Sectton 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 meteorology which apoly to each case were used to calculate the dose resulting from each ccmponent.

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

The annual gamna dose (mrad /yr) resulting from noble gases in elevated plunes was calculated using a modified version of the RADOS(

computer program called MARE This program computes the sector average gamna dose in each of sixteen 221 degree ccmpass sectors on an annual basis.

It assunes that tne radioactive plune is distributed uniformly across the width of each 22) degree sector and is distributed in a Gaussian form in the vertical direction. The total dose at each receptor location is the sumiation of the doses resulting frcm each isotope which is transported and diffused by the same set of meteorological conditions from which X/Q values were derived, including terrain heights, plune rises and vertical dispersion parameters.

Radioactive decay of the noble gases was taken into account during the time of transport from the source to the receptor location.

The source term of isotopes used as input to the MARE program to calculate ganma dose from concentration of noble gases in elevated plumes fran the PBAPS off-gas stack were reported in Peach Bottom Atcmic Power Station Semi-Annual Effluent Release Reports Nos. 21 and 22.

Location No ' 3, Glen Ccve, represents a worst case location J

where a significant amount of Conowingo Pond recreational uses may occur. Therefore, at this location the doses resulting from eating fish, swirrming, boating and shoreline recreation were calculated.

i

drinking water from Conowingo Pond during the last six months of 1986. However, since Conci.:ngo Pond represents only a small fraction of the water supply for the City of Baltimore, j

any,deses resulting frcm this pathway are much smaller than those estimated from drinking water at Concwingo Dam.

The Conowingo Pond usage rates and fish and water consunptIon rates which were used in the calculation of doses for various pathways and locations resulting from Peach Bottom liquid radwaste releases are IIsted in Table V-1.

The basis of each is also listed. Only fish consunption was considered for the aquatic foods pathways in the Peach Bottcm region.

In accordance with Regulatory Guide 1.109

, a shore width factor of 0.2 was utilized for shoreline recreattun. There is no known use of water frcm Conowingo Pond for crop f rrigation; therefore, this pathway was not included. There are no known private residences using Pond water for drinking purposes; therefore, this pathway was not included.

Gaseous Releases In order to assure that the location of the maximtm off-site annual dose to each organ and by each pathway resultIng frcm 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 were two herds of milk goats within five miles of PBAPS.

The locations of real receptors which were evaluated in this study were determined by an extensive field survey during 1976 in the area within Five miles of the release 1-14

g points. The survey was updated by a dairy pasture survey in 1986 which determined the pasture closest to PBAPS in each sector.

Doses via the cow-milk pathway and meat animal pathway a

detennined at the center of dairy pastures were added to doses calculated at the fann residences for the external radiation, inhalation, and vegetation consunption pathway.

The farm residence was assuned to be at the same location as the dairy pasture. Since the cow-mlik-thyroid pathway is the critical pathway by a large margin (see Section V O, this approach assures that the location with greatest total dose frcm all pathways has been evaluated.

In addition to the farm residence locations, annual doses via the external radiation, inhalation and e

vegetation consunption pathways were evaluated at several real residence locations. These locations included the residences with the highest annual X/Q values.

Standard usage factors were used in accordance with Regulatory Guide 1.109(9 and are presented in Table V-2.

VI. CALCULATED AtNUAL DOSES A.

Liquid Releases Tables VI-1 through VI-4 list the calculated annual doses through the various pathways to the maxinun Individual in the adult, teenager, child, and Infant age categories as a result of Peach Bottcm Ilquid radwaste releases. The locations having maxinun estimated doses to an 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 maxinun Individual in cach 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 critical organ is liver.

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

~,

Locatton 3, Glen Cove. The doses frcm these two pathways, however, are a small fraction of the dose resulting frcm eating fish at this location and do not significantly contribute to the total dose.

1-19

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

The dose frcm this pathway, however, is only 25 percent of the maxinun organ dose at Location 1.

B.

Gaseous Releases Table VI-5 lists the annual doses to all organs through each pathway by age group at the location where a persori would receive the largest calculated organ dose. The dose is sun of the contributions from the two components; the E

off-gas stack and the building vents plune. The largest dose contribution to any organ resulted fran the cow-mlik-thyroid pathway at a dairy farm with the pasture located about 5400 feet W of the PBAPS building vents. The organ recel-ing the largest dose is the infant thyroid, which was calculated to receive a total of 7.67E-01 mrem /yr. from all real pathways IIsted in Table VI-5.

Approximately 91% of this total dose resulted from the cow-milk-thryoid pathway, 8% frcm external exposure to noble gases, 1% from Inhalation of air particulates and radiolodines, and less than 0.1% frcm exposure to activity deposited on the ground. No attempt was made to determine the age of distribution of real residents.

Therefore, the assunption that an infant exists at this location could be very conservative.

I-20

Table VI-6 1ists the annual doses *.o 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 Iodine released from PBAPS. This is a residence located about 3800 feet SSE of the PBAPS building vents. This dose was calculated to be 1.22E-01 mrem /yr. to the total body.

The location where a person would receive the largest calculated dose to the skin resulting from exposure to noble gases, particulates and lodine released frcm PBAPS is a residence located about 5'400 feet S of the PBAPS building

{

vents. This dose was calculated to be 2.18E-01 mren/yr. to the skin.

The location where a real person would receive the largest calculated total body dose from exposure to noble gases, partIculates and lodine released from PBAPS due to non-occupational activities inside of the site boundary is at the boat rano approximately 3300 feet NNW of the PBAPS building vents. This dose is calculated to be 6.80E-02 mren/yr. to the total body. The calculated skin dose at this location is 1.22E-01 mrem /yr assuning continuous occupancy.

Assuning 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.

VII. CONCLUSION Table I-1, Introduction and Smmary, suimarizes the maxinun calculated annual doses resulting from Peach Bottom Units 2 and 3 routine 11guld and atmospheric radwaste releases and how they conpare to the 10CFR50 Appendix I design objective dose ilmits.

The maxinun calculated total body dose resulting from Peach Bottom Units 2 and 3 routine 11 auld radwaste releases during 1986 is 0.307 mrem /yr. and occurs at Location 1,1500 ft. downstream from the Peach Bottom Discharge Canal exit. USNRC Regulatory Guide 1.109(9), Table 1 IIsts the 10CFR50, Appendix I, design objective

~

for dose to total body from all pathways as 3 mrem /yr. per reactor. The maxinun calculated total body dose resulting from Peach Bottom liquid radwaste releases is 5.1% of this design objective.

The maxinun calculated dose to any organ resulting from Peach Bottom Units 2 and 3 routine IIquid radwaste releases is 1

0.435 mrem /yr. to liver and also occurs at Location 1.

The Appendix I design objective for dose to any organ frcm all pathways as listed in USNRC Regulatory Guide 1.109(9) is 10 mrem /yr. per reactor. The maxinun calculated dose to any organ resulting from Peach Bottom IIquid radwaste releases is 2.2% of

~.

this design objective.

.--.-_e.,.__.

m

The maximum calculated total body and skin doses occurring at occupied locations resultIng from exposure to noble gases, particulates, and lodines released to the atmosphere by PBAPS were 1.22E-01 and 2.18E-01 mrem /yr. respectively. These values are very small fractions of the 10CFR50 Appendix I design objective dose limits as shown in Table I-1, Introduction and Stenary.

The maximtsn calculated total annual dose to any organ from all nuclides which occurs at any location off site was 7.67E-01 mrem /yr. to an infant's thyroid due to all real pathways at that location. The corresponding value resulting from only radiolodines and air particulates at this location was 7.03E-01 mrem /yr. to the Infant's thyroid.

As indicated in Table I-1, Introduction and Stmnary, this maximtsn dose is a small fraction of the design objective dose limits of 10CFR50 Appendix I IIsted.

The maximtsn calculated total body and skin doses due to non-occupational on-site activities resulting from exposure to gaseous releases to the atmosphere by PBAPS were 6.80-02 and 1.22-02 mrem /yr. respectively. The values are very small fractions of 10CFR50 Appendix I design objective dose limits.

It is concluded that the estimated radiation doses resulting from the routine liquid and atmospheric releases from Peach Bottom Atcrnic Power Station are extremely low and well within the design objectives set forth by 10CFR50 Appendix I.
