Millstone Unit No. 2 (1)

Location should read 3.2 Miles WSW New London.

(2) Measurements and Approximations of Total Radioactivity a) Unit 2 Vent Total cc's out the Unit 2 vent per month is multiplied by the isotopic concentrations as measured by gamma spectrometer GE(L1) analysis of grab samples of gases, lodine, and particulates to obtain total pCi released from the vent.

t b) Containment Purges Grab samples are taken for gaseous, particulate, and iodine.

These are analyzed on GE(Li) gamma spectrometer and concentrations computed. Computed concentrations are then multiplied by the purge volume for total pCi released.,

Tritium collection is by the gas washing bottle method. The sample is counted on a liquid scintilation counter. Concentration is computed using worst possible case, 100% humidity.

Concentration is multiplied by volume purged to give total pCi released..

c) Liquid Effluents There are.three tanks which are used to discharge liquids containing radioactivity to the environs. They are one Aerated Waste Monitor Tank and two Coolant Waste Monitor Tanks.

Prior to release, the tank is recirculated for two tank volumes, a one liter sample is drawn and analyzed on the GE(Li) gamma spectrometer for individual radionuclide composition. An aliquot of the sample is analyzed for Tritium in pCi per cc.

The pCi per cc is multiplied by the cc's released to obtain total pCi released.

The. sample is retained for composite analysis for Sr-89, 90 and gross alpha. The composite contains proportional amounts of each discharge.
