7 In the evaluaticn, the staff usec re:eorolcgical cata collected at the adjacent Nine :til-Pt. : uclear Station site.

Fcr annual average calculaticns, the staff used data collected during 1974 and 1975; for grazing season calculations, the staff used data collected for April through September 1974 and 1975.

Table 5 presents calculated values of relative concentration,(X/Q) and relative deposition (0/0) for specific points of interest.

The su= ary of calculated doses given in Teble 6 are different frcm and replace those given in Table E,+ of the FES.

The staff's dose assessnent considered the folicwing three effluent categories:

1) pathways associated with radioactive materials released in licuid effluents to Lake Ontario, 2) pathways asscciated with ncble gases released to the atmos-phere; and 3) pathways associated with radioicdines, particulates, caroon-14, and tritium released to the atmosphere.

The rathematical models used by the staff to perform the dose calculations to the maximum exposed individual are described in Regulatory Guide 1.109.(II}

The dose evaluatic" of pathways asscciated with the release of radioactive caterials in liquid effluents was based on the maximum excose.d indivicuai.

For the total body dose, the staff considered the maxinum exposed individual to be an adult whose diet included the consunction of fish (21 kg/yr) h'arvested

The dose evaluation of ncble gases released to the at,':osphere included a cal-culation of 'oeta and gamma air doses at the site boundary sector having the highest dose and total bcdy and skin doses at the site boundary sector having the highest dose.

The dose evaluation of pathways asscciated with radiciocine, particulates, carbon-14, and tritium released to the at=csphere was also based cn the maximum exposed individual.

For this evaluation, the staff considered the maximum exposed indivicual to be an infant whcse diet included the consumption of

Using the dose assessnent parameters noted abcve and tne calculated releases of radicactive materials in licuid effluents given in Tacle 1, the staff calculated the annual dose or cose commitnant to the total body or to any organ of an individual, in an unrestricted area, to be less than 3 mrem / reactor and 10 mrem / reactor, restectively, in conformance with Section II. A of Appendix I.

Using the dose assessment carareters noted above, the calculated releases of radioactive naterials in gasecus effluents given in Table 2, and the appro-priate relative concentration (X/0) value given in Table 5, the staff calculated the annual ga. ma anc beta air doses at or beyond the site boundary to be less than 10 mrad / reactor and 20 mrad / reactor, rescectively, in con-formance with Section II.3 of Acpendix I.

Using the dose assessment para eters noted above, the calculated releases of racioicdine, carbon-la, tritium, and particulates aiven in Table 2, and the acpropriate relative concentration (X/0) ano deposition (0/0) values given in Table 5, the staff calculated tne annual dose or dose cccmitment to any organ of the maximum exposed individual to be less than 15 mrer m:ctor in con-fermance with Section II.C of Appendix I.
