EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT Supplemental Information Facility: Seabrook Station Unit 1 Licensee: North Atlantic Energy Service Corporation 1.

Reculatory Limits A.

Gaseous Effluents a.

Fission and activation gases: 5.0 mrad per quarter gamma air dose,10.0 mrad per quarter beta air dose.

b.

Iodines: 7.5 mrem per quarter to any organ, c.

Particulates, half-lives > 8 days: Particulates and iodines are included in step b.

d.

Tritium: 7.5 mrem per quarter to any organ.

c.

Liquid Effluents: 1.5 mrem per quarter total body and 5 mrem per quarter to any organ.

2.

Maximum Permissible Concentrations l

The MPC's used in determining allowable releases rates or concentrations.

Fission and activation gases: 1 MPC a.

b.

Iodines: 1 MPC c.

Particulates, half-lives > 8 days: 1 MPC d.

Liquid effluents: 1 MPC 3.

Averace Enercy Not applicable.

4.

Measurements and Approximations of Total Radioactivity l

Provide the methods used to measure or approximate the total radioactivity in cffluents and the methods used to determine radionuclide composition.

a.

Fission and activation gases: Determined by gamma spectroscopy. Total error is based on stack flow error, analytical error and calculated sampling error.

b.

Iodines:

Determined by collection on charcoal with subsequent gamma spectroscopy analysis. Total error is based on stack flow error, analytical error and calculated sampling error.

Particulates: Determined by collection on fixed filter with subsequent gamma I

spectroscopy analysis. Strontium is determined by composite analysis of filters by liquid scintillation, gross alpha by proportional counter, and iron 55 by l

liquid scintillation. Total error is based on stack flow error, analytical error j

and calculated sampling error.

l l

d.

Liquid Effluents: Determined by gamma spectroscopy. A composite sampic l

is analyzed for strontium by liquid scintillation, tritium by liquid scintillation, j

alpha by proportional counter, and iron 55 by liquid scintillation. Total error is based on the volume discharge error and analytical error.
