A monthly composite is made from weekly samples.

The monthly composite is checked fat for:grossc. alpha and 89se - 90Sr.

d.

Liquid Effluents: In-line scintillation detector monitors waste liquid being released. Prior to discharge a sample is taken. Principal gamma omsitters, entrained gases and tritium analyses are performed. A monthly composite is made from.the weekly samples. Gross Alpha, 89Sr and 90Sr are determined.

OFFSITE DOSE ESTIMATES I

la accordance with the 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 of Connecticut Yankee have been estimated.

These estimations are performed using measured effluent data, measured l

meteorological data, and calculational models developed by the U.S.

Nuclear Regulatery Commission.

i l

l The dose estimates semerally tend to be conservative due to the use of l'

l eeaservative assumpt' ions in the calculational models. More realistic estimates of the off-site done are obtained by analysis of the enviroa-mental monitoring data. A comparison of the doses estimated by each of I

the above methods will be presented in the Ananal Radiological Inviron-mental Monitoring Report due to be published during the first half of 1983.

1.

Dose Models a.

Aitborne Effluents Maximum individual and population doses due to the release of noble gases, radioiodines and particulates were calculated using the computer code GASPARC).

I i - -.

The code uses the semi-infinite cloud model to implement the dose models'of U.S.N.R.C. Regulatory Guide 1.109 (October, 1977).

The values of average relative affluent concentration (I/Q) and average relative deposittaa (D/Q) used la the GASPAR cods were generated using a meteorological computer code which tapiaments the assumptions gives in Section C of NRC Regulatory Guide 1.111. " Methods for i

Estiasting Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Rolesses from Light-Water-Cooled Reactors".

Releases from the CT 175 foot stack were considered am a mined mode release (partially elevated and partially ground). h l'

Fasquill stability-classes were determined using the, temperature gradient between the 33 foot and 196 foot invols of the meteorological SoWera.

The CASPAR code was run separately for contianous releases (building ventilation) and batch releases (weste gas tasks)..

The resulting doses were them summed to determine the total dese.

h calculated doses are presented in Table 5.1.

For population doses, the GASPAR code calculates the dose to the whole body, SI-tract, bone, liver, kidney, thyroid, lung and skin from each of the following pathways: direct exposure from the plume, direct exposure from ground deposition, imbala-tion, vegetation, cow's milk and meat.

The values presented in the attached table are a total from all pathways, but only the whole body, skin and thyroid dose are presented.

6.. _. _ _

j yor the maximum individual, the GASPAR program calculates the dose to the same organs listed above for the following pathways:

direct esposure from the plane, direct esposure from ground

~

deposition, tahalation, vegetation, meat, cow's milk and goat's milk. h doses are calcalated for adults, teenagers, children and infants separately. Unless otherwise meted in the table the doses given are for adults.

For the plume, greemd deposities and inhalation pathways, the sanimum individual dose is calculated at the offsite location of maximum decayed I/Q ubere a potential for dose exists.

For the vegetation pathuey the===i=== individual dose is j

calculated at the vegetable garden of highest D/Q.

j>:

For the meat, cow's milk and goat's milk pathways, the calcu-lated dose is included as the anzimum individuals dose only at locations and times ubere these pathways actually exist.

Doses were calculated at the cow farm and goat farm of maximum deposities. The doses presented la Table 5.1 are the maximum l

doses observed.

Thr IADTAP code perfs ss coleclotices ist th2 is11owing pathways:

fish, shellfish, algae, drinking water, irrigated food, shore-line activity, swisssing and boattag..At Connecticut Yaakee,

' the algae, shellfish, drinking water and irrigated food pathways do not exist, and thus only the other' pathways are included in the totals given la Table '5.1.-

f Doses are calculated for the whole body, skin, thyroid, C1-I.I,1, bone, liver, kidney, and lungs.

Table 5.1 presents the doses to the whole body, thyroid, and the maximum organ dose, which is all cases was to the liver, The dose to all other organs was less than that gives for the i

liver.

Calculations are performed for adults, teenagers, childrea and infants separately. Osless otherwise acted is the table the i

doses gives are adult doses.

3.

Analysis of Results 0

The doses are well below permissable levels and are of me signifi-l cance as far.as effects se the general population. For perspective.

4' l

the average whole body dose to as individual from natural background radiation in the vicinity of Connecticut Tankee is about 40 milliread

..sJ for a six month period as opposed to the average individual dose within 50 miles of the site of 0.000W4 millires from gaseous

(

32 --

effluents and 0.00007 millires from liquid effluents during the report period. The maxiama individual whole body dose of 0.169 milliram from gases or 0.043millires t

from liquids are a fractiort of one percent of the background dose.-
