INTRODUCTION AND

SUMMARY

i 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 1,1992 through December 31,1992.

t

+

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 materials during the reporting period were within 10CFR50 Appendix I limits and with 40CFR190 limits as-l indicated on Table 1-1, Comparison of Doses Resulting from PBAPS Units 2 and 3 l

with 10CFR50 Appendix I Design Objectives. Specifically, the maximum offsite l

dose due to liquid releases was 1.14E-02 mrem; the maximum dose due to gaseous releases was 5.28E-01 mrem.

Since PBAPS releases were well within applicable radioactive effluent technical l

specifications limits and were a small fraction of 10CFR50 Appendix 1 design objectives, it is concluded that PBAPS releases were a small fraction of 40CFR190,

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

STATION LOCATION Peach Bottom Atomic Power Station is located on the western shore of Conowingo f

Pond in York County, Pennsylvania. The station, two 3293 MWT boiling water 2

reactors, is describeo in the Updated Final Safety Analysis Report. Conowingo Pond is the receiving stre-am for liquid radwaste effluents.

l III.

PEACH BOTTOM LIOUID AND GASEOUS RADWASTE EFFLUENTS r

i 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. 33 and 34'*"".

IV.

HYDROLOGY AND METEOROLOGY A.

HYDROLOGY F

Travel times and dilution factors were determined based on the daily Conowingo Pond flows in 1992. Daily Pond flows were reviewed to determine l

a mean monthly Pond flow. Each daily flow value was assigned to one of s

three Pond flow regimes. The resulting daily travel times and dilution factors were then averaged to determine a monthly mean travel time and dilution-i 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.

B.

METEOROLOGY Section VIII describes in detail the meteorology in the PBAPS region during l

1992, 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.

L10UID AND GASEOUS PATHWAY 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 v

in USNRC Regulatory Guide 1.1096 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 l

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, te-enager, 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.

Liouid Releases i

t 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 -

l listed pathway activities are most likely to occur. The locations and pathways l

are:

recreation, swimming 4

Conowingo Dam drinkmg water The City of Baltimore (location 5) withdrew drinking water from Conowingo Pond approximately 55 percent of the year in'1992. Since Conowingo Pend represents only a small fraction of the water supply for the City of Baltimore, any doses resulting from this pathway are much smaller than those estimated from drinking water at Conowingo Dam. The Chester Water Authority j

withdrew drinking water from Conowingo Pond approximately 27 percent of tne year. Usage factors were adjusted accordingly. No other liquid pathway usage and consumption rates used in these calculations changed from previous years'.

i B.

Gaseous Releases j

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 j

pastures were assumed to co-exist with dairy pastures. A dairy pasture survey was performed in' 1992 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 year?.

Tables VII-5 and VII-6 list the annual doses to all organs through pathway by age group 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 1.47E-02 mrem to the child and l

occurred at a residence 3900 feet NNW from the PBAPS building vents. This dose is 0.15% of the 10CFR50 Appendix I design objective.

The maximum calculated organ dose was 5.28E-01 mrem to the infant thyroid -

and occurred at a diary farm 5400 feet S from the PBAPS building vents. This.

dose is 1.76% of the 10CFR50 Appendix I design objective.

l The maximum calculated skin dose was 1.17E-02 mrem at a residence 11800 feet NW from the PBAPS building vents. This dose is 0.04% of the Appendix

I design objectives.

The maximum offsite gamma air dose is 4.94E-03 millirad, located 3900 feet NNW from the PBAPS building vents. This dose is 0.03% of the 10CFR50 Appendix I design objective.

The maximum offsite beta air dose is 1.72E-02 millirad, located libO0 feet NW from the PBAPS building vents. This dose is 0.04% of the 10CFR50 Appendix I design objective.

The location where a person would receive the largest calculated total body l

dose from exposure to PBAPS releases due to non-occupational activities inside the site boundary is at the boat ramp approximately 3300 feet NNW of the i

PBAPS building vents. The calculated total body dose is 1.75E-03 mrem and calculated skin. dose is 3.66E-03 mrem assuming continuous occupancy.

i VIII. METEOROLOGICAL DATA i

The meteorology at the PBAPS site is evaluated by instruments on a meteorological tower on

~

2 the bluff overlooking the plant. It is described in the USFSAR. All data are 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.

CONCLUSION Table I-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 I design objective dose limits. All calculated doses were extremely low and well within the 10CFR50 Appendix I design objective dose limits.
