TECHNICAL SPECIFICATIONS FOR OCONEE RADIOACTIVE EFFLUENTS - TELEPHONE CONVERSATIO'?
Mr. Lionel Lewis of Duke Power called with regard to the staff's recent guidance on the radioactive effluent portion of the Oconee technical specifications. The following points were discussed:
1.
Section Limit vs. Unit Limit - They prefer to write limits in terms of the station including all units because this gives them operational flexibility.
This had been done in the guidance for all effluents, except iodine, since the predicted annual releases for the three units were within Appendix I guidelines.
Because the iodine releases would be greater than Appendix I guideline % the specification was written for a single unit.
It was not thought to be "as low ac practicable" to use a threa unit station limit when only a single unit will be operating at first.
The limit will be increased if necessary as each unit comes on line.
2.
Gaseous Release Limit Expression - They prefer to express a gaseous release li=it as
.Lx42 4
02 q
T unc&
rather than d $15 2Ctl 60 3
T 01sec)t i
~0 3
which for their Tj[ (4.61 x 10 sec/m ) is the same thing.
3.
The Nearest Cow - The nearest cow to Oconee is at the nearest dairy farm which is 4.5 miles west.
There had been a closer cow but itwassoldlagt year.
The applicant calculates a 1%Q at this dairy of.122 x 10-7 sec/m.
4.
Iedine Ralease Limit - They questioned the numerical guidance for the iodine release limit. They had calculated a lower release limit (annual averana.12 C. of I) which is based on the 35$?at the r.earest dairy and the Appendix I limit of (10 CT: 20)/(100,000). The limit sent to them as guidance was based on the AEC source term for one unit.
5.
More Ficxible Caseous Release Limits - The specification for operation of the _ liquid rad waste equipment had been written so that very low level wastes could be released without processing as long as the total release was within Appendix I guidelines on a quarterly basis. They wanted to anolv the same philosphy to gaseous waste hold-up ti=es.
They would write the specification so.that low activity gaseous' wastes could be vented with less than 30 days hold-up if the hold-up tanks were needed for higher _ level gaseous wastes.
The releases at all times would be kept within Appendix I guidelines.
Conclusions reached were 1) they will recalculate the iodine _ release limit,.2) they will rewrite the specification for gaseous vaste hold-up ti=e and, 3) they will thihk about writing the limit for iodine based on single unit releases.
