i Statement.
Technical background for our effluent release estimates have been incor-porated into the text and a separate summary of assumptions is attached including a list of references used in our evaluation for future reference.
The release The source terms were based on a power level of 2,452 MWt.
estimates were based on simultaneous operation of Units 1, 2 and 3.
In accordance with your request the estimated releases of radioactive materials in liquid waste were transmitted directly to ORNL on February 29, Although the anticipated quantities of activity were a fraction 1972.
of those shown in Table 2 the values have been normalized to 1 curie per year per unit to account for treatment equipment outages and expected The anticipated gaseous releases shown in Table 1 operating occurrences.
do not include effluents associated with a leak of primary coolant into Based on a 5 gallon per day leak the limiting the auxiliary buildings.
isotope Ie-133 is less than 10% of the value shown in Table I and for this reason it was not Jacluded, however the technical background contains a summary of this data for your information.
In reference 7, the applicant acknowledges that consideration was given to additional modifications particularly the Easeous vaste treatment system such as filters and a cryogenic system, however the applicant is convinced that such improvements would be of negligible value in view of the already small quantities of activity 'nticipated to be released from the station.

. In our evaluation we have considered releases based on a 30 day holdup of gaseous waste which we estimate to be the capacity of the presently installed equiptnent. In view of agency comments we have also calculated and attached estimated gaseous releases using a 60 day holdup period.
We recocenend that the radiological environmental impact be performed for both holdup times in order that we may verify the applicant's conclusion that additional gaseous waste treatment equipment is not warranted.
