I. 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 Bottom Atomic Power Station Units 2 and 3 for the period January 1,1994 through December 31,1994. }
i Detailed discussion of the methodology utilized in the report has been provided in a' i previous report'. Only in those cases where the methodology has been changed will !
it be discussed in detail. !
t The radiation doses due to the release of radioactive materials during the reporting ;
period were well below 10CFR50 Appendix I and 40CFR190 limits. A comparison l of the calculated doses to the appropriate limits is presented on Table I-1, i Comparison of Doses Resulting from PBAPS Units 2 and 3 with 10CFR50 !
Appendix I Design Objectives. Specifically, the maximum offsite dose due to i liquid releases was 8.24E-02 mrem; the maximum dose due to gaseous releases was [
4.17E-01 mrem. I 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 40CFR190, !
" Environmental Radiation Protection Standards for Nuclear Power Operation" limits. t I

-l
-. r 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 and 3293 MWt),'is described in the Updated Final Safety Analysis Report2 , j
' Conowingo Pond is the receiving stmam for liquid radwaste effluents. !
III. PEACH BOTTOM LIOUID AND GASEOUS RADWASTE EFFLUENTS l
The release of radioactive materials in liquid and gaseous effluents from PBAPS l were reported in the Peach Bottom Atomic Power Station Annual Effluent Release .
Report No. 373 IV. HYDROLOGY AND METEOROLOGY A.. HYDROLOGY Travel times and dilution factors were determined based on the daily l' Conowingo Pond flows in 1994. Daily Pond flows were reviewed to determine a mean monthly Pond flow. Each daily flow value was assigned to :
one of three Pond flow regimes4 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.
i I
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. ;
i B. METEOROLOGY !
Section VIII describes in detail the meteorology in the PBAPS region during !
1994, 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. IJOUID AND GASEOUS PATHWAY DOSE'MODRYR l 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 1.1095 and the models described therein. Computer
~
j codes, LADTAP and GASPAR, which incorporate the computational models !
described in Regulatory Guide 1.109 and which were obtained from the NRC staff' l were used to perform the liquid and gaseous dose calculations respectively.
l 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 l 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 wem evaluated for the -
adult, teenager, child and infant age groups. The dose calculation at each receptor !
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 USAGE FACTORS FOR ANNUAL DOSE -
EVALUATIONS
- A. - 1.iauid Releases e
The annual doses resulting for PBAPS liquid radwaste releases were calculated at various locations on Conowingo Pond. The locations am 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 1 are:
I Location Number Name Pathways 1 1500 feet below discharge boating, fish -
i 2- Chester Water Authority drinking water l 3 Glen Cove boating, fish, shoreline j recreation, swimming ;
4 Conowingo Dam drinking water, fish, l
boating i i
The City of Baltimore (location 5) withdrew drinking water from Conowingo j Pond for only 48 days in 1994. Since Conowingo Pond represents only a :
small fraction of the water supply for the City of Baltimore, any doses l resulting from this pathway are much smaller than those estimated from j drinking water at Conowingo Dam. The Chester Water Authority withdrew i drinking water from Conowingo Pond approximately 60 percent of the year. 1 Usage factors were adjusted accordingly. No other liquid pathway usage and j consumption rates used in these calculations changed from previous years'. j 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 1994 which detennined the pasture closest to PBAPS in each sector. There were no herds of milk goats within five miles of PBAPS. No F gaseous pathway usage and consumption rates used in these calculations f changed from previous years7.

IX. CONCLUSION Table I-l', Introduction and Summary, summarized the maximum calculated annual doses resulting from Peach Bottom Atomic Power Station Units 2 and 3 toutine liquid j
- and atmospheric radwaste releases and how they compare to the 10CFR50 Appendix I-design objective dose limits. All calculated doses were extremely low and well within !
the 10CFR50 Appendix I design objective dose limits.
