i I. INTRODUCTION AND
SUMMARY
i In accordance with the reporting requirements of Peach Bottom ODCM Section 3.10 applicable during the reporting period, this report summarizes the radiation doses due to radioactive effluent releases from Peach Bottom Atomic Power Station Units 2 and 3
. for the period January 1,1996 through December 31,1996.
Detailed discussion of the methodology utilized in the report has been provided in a previous report (Ref.1). Only in those cases where the methodology has been changed ,
will it be discussed in detail. l i
The radiation doses due to the release of radioactive materials during the reporting !
- period were well below 10CFR50 Appendix I and 40CFR190 limits. A s omparison of the calculated doses to the appropriate limits is presented on Table 1-1, Comparison of Doses Resulting from PBAPS Units 2 and 3 with 10CFR50 Appendix 1 Design Objectives. Specifically, the maximum offsite dose due to liquid releases was 3.13E-04 mrem; the maximum dose due to gaseous releases was 2.83E-03 mrem. [
r 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 within 40CFR 190, " Environmental Radiation Protection Standards for Nuclear Power Operation" limits.

t 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 boiling water reactors (3458 MWt), is described in the Updated Final Safety Analysis Report (Ref. 2). Conowingo Pond is the receiving stream for liquid radwaste effluents.
III. PEACil HOTTOM I,10lilD AND G ASEOIIS R AI) WASTE EFFl.IIENTS The release of radioactive materials in liquid and gaseous effluents from PBAPS were reported in the Peach Bottom Atomic Power Station Annual Effluent Release Report No. 39 (Ref. 3).
I V. IIYDROI.OGY AND METEOROI.OGY A. IlYDROI.OGY .
Travel times and dilution factors were determined based on the daily Conowingo Pond flows in 1996. 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 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 flow regime.
- 11. METEOROI.OGY Section Vill describes in detail the meteorology in the PB APS region during 1996 l affecting the atmospheric dispersion and the deposition of radionuclides from j PBAPS gaseous radwaste releases. This meteorology was used for the evaluation ,
l of PBAPS Units 2 and 3 gaseous releases.

V. I,10UID AND G ASEOUS PATHWAY DOSE MODELS The maximum annual doses to individuals in unrestricted areas which could result from effluent releases from PB APS were calculated according to the guidelines in USNRC Regulatory Guide 1.109 (Ref.5) and the models described therein. Computer codes, LADTAP and G ASPAR, 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 which 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 groupr The dose calculation at each receptor was done in two parts - a dose component resu. '.7.e from the off-gas stack and one from the building vents. These doses were then sumn ed to yield a total dose for each pathway and organ.

. The annual doses resulting for PBAPS liquid radwaste releases 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 Pathwa.ys 1 1500 feet below discharge boating, fish 2 Chester Water Authority drinking water 3 Glen Cove boating, fish, shoreline recreation, swimming 4 Conowingo Dam drinking water, fish, boating The City of Baltimore (map location 5) did not withdraw drinking water from Conowingo Pond in 1996. Since Conowingo Pond represents only a small fraction of the water supply for the City of Baltimore, any doses that would result from this pathway would be much smaller than those estimated frorn drinking water at Conowingo Dam. The Chester Water Authority withdrew drinking water from Conowingo Pond approximately 27 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 (Ref. 6).
H. G ASEOllS REI EASES 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 1996 which determined the pasture closest to PB APS 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 calculations changed from previous years (Ref. 7).

VIII. METEOROLOGICAL DATA
- The meteorology at the PBAPS site is evaluated by instruments on a meteorological tower on the bluff I overlooking the plant, it is described in the UFSAR (Ref. 2). All data are summarized using the Pasquill-Gifford 4
system.' The following three tables present the annual summary of hourly meteorological data joint frequency ,
- distributions of wind speed, wind direction and aimospheric stability.

q e IX. CONCI.liSION Table 1-1, Introduction and Summary, summarized the maximum calculated annual doses resulting from Peach Bottom Atomic Power Station Units 2 and 3 routine liquid and atmospheric radwaste releases and how they compare to the 10CFR50 Appendix
! design objective dose limits. All calet lated doses were extremely low and well within the 10CFR50 Appendix I design objective dose limits.
