DUQUESNE LIGHT COMPANY Beaver Valley Fower Station Docket No. 50-334, License No. DPR-66 Semi-Annual Effluent Report In accordance with the requirements of Section 5.6.1.B of the Environmental 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 The maximum individual whole body and skin dose was calculated using the values in the Environmental Technical Specifications.
The population dose 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 assessments.
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 to input to GASPAR.
Except when more recent or specific data was available, all inputs were_the same as used in the Beaver Valley Power Station Environmental Statements or in Regulatory Guide 1.109.
B.
Liquid Effluents The radiation doses to man from liquid effluents were calculated using NRC computer code LADTAP.
All potentially radioactive liquid effluents, including steam 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 is located at Midland.
Except when more recent or specific data for the period is available, all other input to LADTAP are obtained from the Beaver Valley Power Station Environmental Statement or Regulatory Guide 1.109.
Pathways, which were evaluated, are drinking water, fish consumption, and shoreline recreation.

SUMMARY
OF RESULTS (continued)
==
Conclusions:==
The operation of Beaver Valley Power Station, Unit 1, has resulted in an insignificant incremental dose to that which area residents already receive as a result of natural background and this dose will constitute no meaningful risk to be balanced against the benefits of the plant.
