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 - 3,514 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).

Ill.

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. 48 (Ref. 3) per ODCMS 3.10.2.

IV.

PEACH BOTTOM LAND USE SURVEY A dairy pasture survey was performed in 2005, which determined the milk-producing animal (cow or goat) closest to PBAPS in each sector per ODCMS 3.8.E.2.

V.

HYDROLOGY AND METEOROLOGY A.

Hydrology Travel times and dilution factors were determined based on the daily Conowingo Pond flows in 2005. 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). The annual average of 2.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> travel time and 1.5 dilution factor were used for dose calculations for this receptor.

Meteoroloqy 2.5 2.4 2.1 1.9 0.9 1.6 2.0 1.9 Appendix A details the 2005 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.

Regulatory Guide 1.23, Onsite Meteorological Programs, requires meteorological instruments be inspected and serviced at a frequency which will assure at least a 90% data recovery. ANSI/ANS 3.11-2000, Determining Meteorological Information at Nuclear Power Sites, requires a 90 percent joint data recovery for atmospheric stability, wind speed and direction at levels that represent potential release points. The data 4

Peach Bottom Atomic Power Station 2005 Radiation Dose Assessment Report recovery for Tower 2 75 ft. level was 97.6% and for Tower 2 320 ft. level was 98.2%.

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 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, and 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-1). 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.

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) 5

Peach Bottom Atomic Power Station 2005 Radiation Dose Assessment Report 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 effluents from the Unit 2 and Unit 3 off-gas stack and roof vents, using the dispersion methodologies of USNRC Regulatory Guide 1.111 (Ref. 7). The XOQDOQ computer program was used to perform the calculations.

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 (144A, 1,200 feet ENE) 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, and cow'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 2005 was completed to comply with ODCMS Section 3.10.3. For purposes of this report, the security checkpoint (114A) 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 was assumed.

Approximately 495 Ci of unidentified gaseous radioactive effluent activity released from PBAPS in 2005 were assigned to Kr-88 for calculating the Gamma Air, Beta Air and Plume doses. Kr-88 has the highest dose factor for gamma air dose, which is normally limiting, therefore the analysis remains conservative.

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 VI1-1). The maximum doses were as follows:

MAXIMUM PERCENT OF I0CFR50 DOSE PATHWAY CALCULATED APPENDIX I DOSE (mrem)

DESIGN OBJECTIVE ADULT TOTAL BODY 1.90E-03 0.03%

ADULT LIVER 2.30E-03 0.01%

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 )XJQ value for the Unit 2 and Unit 3 roof vents and off-gas stack releases. The two locations were 1,200 feet ENE of the PBAPS Unit 2 and Unit 3 roof vents (Table V1I-2) and 15,000 feet N of the PBAPS Unit 2 and Unit 3 off-gas stack (Table V1I-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 1,200 feet ENE of the PBAPS Unit 2 and Unit 3 roof vents. Therefore, doses to other geographical areas would be less. The maximum calculated doses were as follows:

MAXIMUM PERCENT OF ODCM AND DOSE PATHWAY CALCULATED 10CFR5O APPENDIX I DOSE DESIGN OBJECTIVE Child Total Body 3.51 E-01 3.51%

Infant Thyroid 7.58E+00 25.3%

Child Skin 4.64E-01 1.55%

Gamma Air Dose 4.87E-01 2.44%

Beta Air Dose 9.77E-02 0.24%

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 1.46 E-01 mrem and 1.81E-01 mrem, respectively (Table V11-4).

ENVIRONMENTAL MONITORING CHANGES A. Milk Sampling The control milk farm A in the WSW sector at 30,493 feet went out of the milking business. The control farm was replaced by farm T in the W sector at about 34,581 feet. No milk samples were missed as a result of the change of milk farms. Proposed changes to the ODCM are found in APPENDIX B.

B. Direct Radiation TLD 1 K was added in the SW sector at 4,604 feet. The TLD was added to comply with ODCMS Table 4.8.E.1.1 requirement for TLD stations in the general area of the SITE BOUNDARY and a residence at the location. Proposed changes to the ODCM are found in APPENDIX C.

IX.

ISFSI DOSES The Independent Spent Fuel Storage Installation (ISFSI) had no liquid, gaseous or particulate releases in 2005. 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 individual.

X.

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 small and well within ODCMS,1 OCFR50 Appendix I design objectives, IOCFR72.104, and 40CFR190 dose limits.
