1. INTRODUCTION AND

SUMMARY

In accordance with the unique reporting requirement of Technical Specification 6.9.2 applicable during the reporting period, this report summarizes the radiation doses due to radioactive effluent releases from Peach Ilottom Atomic Power Station Units 2 and 3 for the period January 1,1993 through December 31,1993.

Detailed discussion of the methodology utilized in the report has been provided in a previous report'. Only in those cases where the methodology has been changed will it be discussed in detail.

The radiation doses due to the release of radioactive materiais during the repoiting period were well below 10CFR50 Appendix 1 and 40CFR190 limits. A comparison of the calculated doses to the appropriate lirnits is presented on Table I-1, Comparison of Doses Resulting from P13APS Units 2 and 3 with 10CFR50 Appendix 1 Design Objectives. Specifically, the maximum offsite dose due to liquid releases was 1.53E-03 mrem; the maximum dose due to gaseous releases was 8.09E-01 mrem.

Since PilAPS releases were well within applicable radioactive effluent technical specifications limits and were a small fraction of 10CFR50 Appendix 1 design objectives, it is concluded that PBAPS releases were within 40CFR190,

" Environmental Radiation Protection Standards for Nuclear Power Operation" limits.

II. STATION I.OCATION Peach Bottom Atomic Power Station is located on the western shore of Conowingo Pond in York County, Pennsylvania. The station, two 3293 MWT boiling water reactors, is described in the Updated Final Safety Analysis Report2 . Conowingo Pond is the receiving stream for liquid radwaste effluents.

Ill. PEACil BOTTOM LIOUID AND GASEOUS RADWASTE EFFLUENTS The release of radioactive materials in liquid and gaseous effluents from PBAPS were reported in the Peach Bottom Atomic Power Station Semi-annual Effluent Release Reports Nos. 35 and 363 *"'"

IV. IlYDROLOGY AND METEOROLOGY A. IlYDROLOGY Travel times and dilution factors were determined based on the daily Canowingo Pond flows in 1992. Daily Pond Dows were reviewed to determine a mean monthly Pond flow. Each daily flow value was assigned to one of three Pond flow regimes'. 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 travel times and dilution factors for those locations in Conowingo Pond, where the highest doses were calculated, are listed in Table IV-1 for each monthly now regime.

B. METEOROLOGY Section Vill describes in detail the meteorology in the PBAPS region during 1993, affecting the atmospheric dispersion and the deposition of radionuclides from PBAPS gaseous radwaste releases. This meteorology was used for the evaluation of PBAPS Units 2 and 3 gaseous releases.

V. LIOUID AND GASEOllS PATilWAY DOSE MODELS The maximum annual doses to individuals in unrestricted areas which could result from the effluent releases from PBAPS were calculated according to the guidelines in USNRC Regulatory Guide 1.107' 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.

The liquid release pathways which were considered in making these calculations included drinking water, aquatic foods, shoreline usage, swimming and boating. All pathways were calculated using the equations and dose factors provided in the LADTAP computer code.

The gaseous release pathways wnich 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 age groups. The dose calculation at each ieceptor was done in two parts - a dose component resulting from the off-gas stack and one from the building vents. These doses were then summed to yield a total dose for each pathway and organ.

VI. RECEPTOR LOCATION AND (1 SAGE FACTORS FOR ANNtJAL DOSE EVAll1 ATIONS A. Liould Releases The annual doses resulting for PBAPS liquid radwaste teleases were calculated at various locations on Conowingo Pond. The locations are shown in Figure VI-1. These locations were selected because they represent areas where the listed pathway activities are most likely to occur. The locations and pathways are:

Location Number Name Pathways I 1500 feet below discharge boating, fish 2 Chester Water Authority drinking water 3 Glen Cove boating, fish, shoreline recreation, swinuning 4 Conowingo Dam drinking water The City of Baltimore (location 5) withdrew drinking water from Conowingo Pond only one day in 1993. This results in an inconsequential dose compared that estimatea from drinking water at Conowingo Dam. The Chester Water Authority withdrew drinking water from Conowingo Pond approximately 35 percent of the year. Usage factors were adjusted accordingly. No other liquid pathway usage and consumption rates used in these calculations changed from previous years'.

B. Gaseous Releases 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. A dairy pasture survey was performed in 1993 which determined the pasture closest to PBAPS in each sector. There were no herds of milk goats within five miles of PBAPS. No gaseous pathway usage and consumption rates used in these calculation changed from previous years" 6

VII. CALCULATED ANNUAL DOSES A. Liould Releases Tables VII-l through Vll-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 PBAPS liquid radwaste releases.

The maximum calculated total body dose was 4.87E-04 mrem.to the adult and occurred at Location 1,1500 feet downstream from the PBAPS Discharge canal exit. This is 0.008% of the 10CFR50, Appendix I design objective.

The maximum calculated dose to any organ was 1.57E-03 mrem to the child bone and also occurred at Location 1. This dose is 0.008% of the 10CFR50 Appendix I design objective.

B. Gaseous Releases Tables VII-5 and VII-6 list the annual doses to all organs through pathway by age gro .p at the location where a person would receive the largest calculated total body and organ dose respectively resulting from exposure to noble gases, particulates and iodine released from PBAPS.

The maximum calculated total body dose was 1.65E-02 mrem to the child and occurred at a residence 3900 feet NNW from the PBAPS building vents. This dose is 0.16% of the 10CFR50 Appendix I design objective.

The maximum calculated organ dose was 8.09E-01 mrem to the infant thyroid and occurred at a diary farm 6600 feet SSW from the PBAPS building vents.

This dose is 2.70% of the 10CFR50 Appendix I design objective.

The maximum calculated skin dose was' 2.73E-02 mrem at a residence 6000 feet SSE from-the PBAPS building vents. This dose is 0.09% of the' Appendix l I design objectives. .!

.q The maximum calculated offsite gamma air dose was 1.05E-02 millirad, located 3900 feet NNW from the PBAPS building vents. This dose is 0.05%

of the 10CFR50 Appendix I design objective.

~

The maximum offsite beta air dose is 2.48E-02 millirad, located 6000 feet SSE-from the PBAPS building vents; This dose is 0.06% of th'el10CFR50 Appendix' I design objective.

The location where a person would receive the largest calculated toid body-8 w -- '

',3:,

1 dose from exposure to PilAPS releases due to non-occupational activities inside the site boundary is at the boat ramp approximately 3300 feet NNW of the PilAPS building vents. The calculated total body dose is 2.99E.03 mrem and-calculated skin dose is 7.32E-03 mrem assuming continuous occupancy, Assuming the shoreline recreational usage factor (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 even more insignificant dose, t
