DUQUESNE LIGHT COMPANY Beaver Valley Power Station Docket No. 50-334, License No. DPR-66 9
Semi-Annual Effluent Report Off-Site Dose Estimates - First and Second Quarters, 1980 In accordance with requirements of Section 5.6.1.B of the Environ-mental Technical Specifications and Regulatory Guide 1.21, the off-site dose to humans from the gaseous and liquid radioactive effluents have been estimated.
Dose Models A.
Airborne Effluents All doses as a result of Beaver Valley operation were calculated for gaseous pathways using NRC computer code GASPAR.
All gaseous effluent releases, including Auxiliary Building Ventilation, were included in dose essessments. The data obtained from the analyses required by the Technical Specifications, were used as input. Meteorological data collected by the Beaver Valley Power Station meteorology system was also used in input to GASPAR.
Except when more or specific data was available, all inputs were the same e on the Beaver Valley Power Station Environ-mental Statements er in Regulatory Guide 1.109.
B.
Liquid Effluents The radiation doses to man from liquid effluents were calculated using NRC computer code LADTA?.
i All potentially radioactive liquid effluents, including steam I
generator blowdown, are released by batch mode after analysis by gamma spectrometry using a GeLi detector. The actual data from these analyses are tabulated and used as the input term for sources in LADTAP. The maximum individual for liquid pathways i
is located at Midland.
Except when more recent or specific data for the period is available, all other input to LADTAP are obtained j
from the Beaver Valley Power Station Environmental Statement or l
ReEulatory Guide 1.109.
Pathways, which were evaluated, are drinking water, fish consumption, and shoreline recreation.
