Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report EXECUTIVE

SUMMARY

In accordance with the reporting requirements of Peach Bottom Offsite Dose Calculation Manual Specifications (ODCMS) Sections 3.8.E.2 and 3.10.3, this report summarizes the radiation doses due to the radioactive effluent releases from Peach Bottom Atomic Power Station Units 2 and 3 for the period January 1, 2002 through December 31, 2002.

The 2002 calculated doses were compared to the appropriate ODCMS and Appendix I Design Objective limits (Table 1-1). The maximum offsite total body dose, due to liquid releases was 1.01 E-02 mrem. The maximum offsite total body dose, due to gaseous releases was 1.70 E-01 mrem.

The PBAPS radioactive releases and the doses that were conservatively calculated were well within all applicable Radioactive Effluent Technical Specifications, ODCMS, 10CFR50 Appendix I design objective dose limits.

Therefore, we conclude that doses from PBAPS releases were within I OCFR72.104 and 40CFR190 limits of 25 mrem - total body, 75 mrem - thyroid and 25 mrem - any other organ to a real individual.

Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report

11. INTRODUCTION Peach Bottom Atomic Power Station is located on the western shore of Conowingo Pond in York County, Pennsylvania. The station, two boiling water reactors (U2 - 3,514 MWt, U3 - 3,458 MWt), was described in the Updated Final Safety Analysis Report (Ref. 2). Conowingo Pond was the receiving stream for liquid radwaste effluents.

Detailed discussion of the methodology utilized in the report has been provided in a previous report (Ref. 1). Report No. 14 discussed that all future reports will be calculating doses using a bounding analysis (Ref. 6).

IIl. PEACH BOTTOM LIQUID AND GASEOUS RADWASTE EFFLUENTS The releases of radioactive material in liquid and gaseous effluents from PBAPS were reported in the Peach Bottom Atomic Power Station Effluent Release Report No. 45 (Ref. 3) per ODCMS 3.10.2 IV. PEACH BOTTOM LAND USE SURVEY -.

A dairy pasture survey was performed in 2002, which determined the milk- I producing animal (cow or goat) closest to PBAPS in each sector per ODCMS 3.8.E.2. A small number of goats (2-4) were identified in the SSW sector at 2.2 miles from PBAPS. Milk, when available from these goats was used for home consumption. Due to the small number of animals, this farm was not added to the radiological environmental monitoring program. Additionally, no changes to the ODCM were required as a result of this survey.

V. HYDROLOGY AND METEOROLOGY A. HYDROLOGY Travel times and dilution factors were determined based on the daily Conowingo Pond flows in 2002. Daily Pond flows were reviewed to determine a mean monthly Pond flow. Each daily flow value was assigned to one of three Pond flow regimes (Ref. 4). The resulting daily travel times and dilution factors were then averaged to determine a monthly mean travel time and dilution factor for nearest receptor location, 1,500 feet below the discharge (Table V-1).

METEOROLOGY Appendix A details the 2002 meteorology affecting the atmospheric dispersion and the deposition of radionuclides from PBAPS gaseous effluent releases.. This meteorology was used in the calculation of doses, due to radioactive effluents from PBAPS Units 2 and 3 offgas stack and roof vents.

VI. LIQUID AND GASEOUS PATHWAY DOSE MODELS A. LIQUID DOSE MODEL The maximum annual doses to individuals in unrestricted areas that could result from the liquid effluent releases from PBAPS were calculated according to the guidelines in USNRC Regulatory Guide 1.109 (Ref.5) and 6

Peach Bottom Atomic PoNver Station 2002 Radiation Dose Assessment Report the models described therein. NRC computer code, LADTAP, was used to perform these dose calculations.

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

A bounding dose analysis method was used to calculate total body, organ, ard skin doses due to liquid releases, assuming that all pathways (i.e.,

drinking water, aquatic foods, shoreline usage, swimming, and boating) existed at the receptor location-1,500 feet below the plant discharge (Figure VI-). The highest usage factors determined for Conowingo Pond were used for each pathway for conservatism. Table VI-1 below indicates the bounding usage factors for this location. The shoreline width factor was also set at 0.2, the highest factor in Conowingo Pond.

Table VI-1 Bounding Usage Factors for Receptor Location 1500 feet below the Plant Discharge Factor Adult Teen Child Infant Eating Fish (kg/yr) '21 16.9 6.9 0 Drinking Water (/yr) '730 510 510 330 Shoreline Use (hr/yr) 325 325 14 0-Swimming (hr/yr) 280 280 0 - 0 Boating (hr/yr) 325 325 67 0 B. GASEOUS PATHWAY MODEL:

The maximum annual doses to individuals in unrestricted areas that could result from the gaseous radioactive effluents from PBAPS were calculated according to the guidelines in USNRC Regulatory Guide 1.109 (Ref.5) and the models described therein. NRC computer code, GASPAR, was used to perform these dose calculations.

The annual average X/Q, depleted X/Q and D/Q values were computed to a distance of 50 miles for gaseous radioactive effluent's from the Unit 2 and Unit 3 off-gas stack and roof vents, using the dispersion methodologies of USNRC Regulatory Guide 1.1 11 (Ref. 7) with two differences. The first difference a. the utilization' of the site-specific plume rise equations for the roof vents radioactive effluent releases developed in the PBAPS smoke test. These equations were used with the USNRC Regulatory Guide 1.111 wake split criteria for vent stacks releases. The second difference was the utilization of deposition velocity to compute D/Q from the depleted X/Q values, rather than the use of USNRC Regulatory Guide 1.111 D/Q curves.

7

Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report Using GASPAR, two bounding dose calculations were performed for the receptor locations with the highest X/Q from the Unit 2 and Unit 3 roof vents (154A, 1,300 feet E) and from the Unit 2 and Unit 3 off-gas stack (2068A, 15,000 feet N) (Figures VI-1 and VI-2, respectively). Gaseous release pathways 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. To assure that this analysis was conservative, it was assumed that all pathways existed at these two locations.

In addition to the bounding dose analysis calculation, an analysis for determining the doses from gaseous radioactive effluents to members of the public due to their activities inside the site boundary during 2002 was completed to comply with ODCMS Section 3.10.3. For purposes of this report the security checkpoint located 1,300 feet N of the PBAPS Unit 2 and Unit 3 roof vents was chosen (Figure VI-1). This on-site location was used for measuring inhalation, plume and ground shine doses to the National Guardmen and State Police. Continuous occupancy (2080 hours0.0241 days <br />0.578 hours <br />0.00344 weeks <br />7.9144e-4 months <br />) was assumed.

Approximately 380 Ci of unidentified gaseous radioactive effluent activity released from PBAPS in 2002 were assigned to Kr-87 for calculating the Beta Air Dose and to Kr-88 for calculating the Gamma Air and Plume doses. These two nuclides have the highest dose potential and therefore, the analysis remains conservative.

Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report VII. CALCULATED ANNUAL DOSES A. Liquid Releases The annual doses for the maximum exposed organ in the adult, teenager, child, and infant age categories was calculated at the highest receptor location, 1,500 feet below the discharge (Table VII-1). The maximum doses were as follows: -

MAXIMUM PERCENT OF IOCFR5O DOSE PATHWAY CALCULATED APPENDIX I DOSE (mrem) DESIGN OBJECTIVE ADULT TOTAL BODY 1.01 E-02 0.17%

ADULT GI-LLI 1.42 E-02 0.07%

B. Gaseous Releases The annual offsite doses to all organs through all pathways by age group were calculated at the two locations with the highest annual average X/Q value for the Unit 2 and Unit 3 roof vents and off-gas stack releases. The two locations were 1,300 feet E of the PBAPS Unit 2 and Unit 3 roof vents (Table VII-2) and 15,000 feet N of the PBAPS Unit 2 and Unit 3 off-gas stack (Table VII-3). A review of the calculated doses indicated that the offsite location where a person would receive the largest calculated total body, skin and organ doses was 1,300 feet E of the PBAPS Unit 2 and Unit 3 roof vents. This location is in Conowingo Pond. Therefore, doses to other geographical areas would be less. The maximum calculated doses were as follows:

MAXIMUM PERCENT OF ODCM AND DOSE PATHWAY CALCULATED 10CFR50 APPENDIX I DOSE DESIGN OBJECTIVE Child Total Body 1.70 E-01 (mrem) - 1.70%

Infant Thyroid 1.95 E-01 (mrem) 0.65%

Child Skin 3.34 E-01 (mrem) 1.11%

Gamma Air Dose 2.49 E-01 (mrad) 1.25%

Beta Air Dose 1.53 E-01 (mrad) - 0.38%

C. -Non-Occupational Activity The location where a person would receive the largest calculated total body dose from exposure to PBAPS gaseous radioactive effluent releases due to non-occupational activities inside the site boundary was at the Security checkpoint, approximately 1,300 feet N of the PBAPS Unit 2 and Unit 3 roof vents. Assuming continuous occupancy, the calculated total body and skin doses were 1.02 E-01 mrem and 2.03 E-01 mrem, respectively (Table VII-4).

Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report Vill. ISFSI DOSES The Independent Spent Fuel Storage Installation (ISFSI) had no gaseous or particulate releases in 2002. Direct radiation measurements made at the site boundary indicated no increase in ambient radiation levels from the ISFSI operation. Therefore, the annual doses were within 10CFR72.104 limits of 25 mrem - total body, 75 mrem - thyroid and 25 mrem - any other organ to a real indivdual.

IX. CONCLUSIONS Using conservative methodologies (i.e. bounding analysis with the highest annual average X/Q receptor locations with all pathways available) has shown that the calculated doses were extremely small and well within ODCMS, 10CFR50 Appendix I design objectives, IOCFR72.104, and 40CFR190 dose limits.

Peach Bottom Atomic Power Station 2002 Radiation Dose Assessment Report APPENDIX A - METEOROLOGICAL DATA The meteorology at the PBAPS site was evaluated by instruments on a meteorological tower on the bluff overlooking the plant and was described in the UFSAR (Ref. 2). All data were summarized using the Pasquill-Gifford system.

The following three tables present the annual summary of hourly meteorological data joint frequency distributions of wind speed, wind direction, and atmospheric stability at the three elevations of concern.
