9 29 MEMORANDUM FOR:

Harold Peterson, Jr., RHSB, SD FROM:

Roger Blond, PAS, RES

SUBJECT:

INIT!AL ESTIMATE OF RELEASED SOURCE TERM FOR TMI

' The enclosed figures give a very rough estimate of an initial source term that was potentially available in the auxiliary building for release to atmosphere.

The following assumptions were used to make the estimates:

1.

Suma pumps in containment could potentially pump at 200 ppm or a total of 12,000 gallonpof primary coolant were pumped ::er hour.

The curves, WeFdrore, are for 8,000 gallons of primary coolant.

Points are also given on the hourly figure assuming 40,000 gal.lons of primary coolant were pumped at 8,000 gallons per hour for five hours.

2.

Inventories were calculated as follows:

The Bettis Analysis of the crimary coolant (including makeup water) showed 6500 uci/cc of I-133 tD8 hours af ter the accident. This is ecuivalent to 31,450 uci/cc at the time of the accident; assuming no dillution*.

From a ratio of Origin core inventories, we estimated the F-135 concentration in the primary coolant tc be 29354 uci/cc at the time of the accident.

This is ecuivalent to 830 ci/ gal of I-33 and 770 ci/ gal of I-135 6For 8,000 gallons of primary coolant, there should be curies of I-133 and 6.16x106 curies of I-135.

The 6.64x10 Xenon source was assumed to come solely from decay of the iodine.

  • Makeup water could have dilluted the primary coolant.
