P.eracking of existing spent fuel p:31s at Oconee to accer.odate more fuel was considered early in the operation phase cf the station. The spent fuel pool serving Unit 3 was reracked in 1975, thereby adding to the storage capacity.
It was thought at the titre that this expanded storage capacity would be adequate.
liowever, the reprocessing problems discussed in Section 9.1 have required the applicant to store more fuel for an indefinite period of time, causing an imminent shortage of stcrage space.
{
Raracking of the spent fuel pool serving C:ones Units 1 and 2 would 3,
alleviate the ' hortage,of storage space f:
an interim period of time.
The s
'}
estimat2d time delay in completing the rera: king of this pcol is 15 months.
f This time delay involves lead time to d5 sign, contract, f abricate and install
[
Jhe new racks.
In addi': ion to reracking the basin, the pool cooling system f
would need to be expanded.
Presently the pool has two cooling. trains uith I,'
4 7
cooling capacities of 1.5 x 10 tiJ/hr (1 32 x 10. Btu /hr) each.
An 3
6 additional 6.4 x 10 tiJ/hr (6.1 x 10 Btu /hr) of cocling capacity would be required to meet maximum load requirements, if the pool were to be reracked.
14aximum load is based on a storage capacity of 350 assemblies / with the pool full including a full core of fuel cooled seven days.
The applicant has estimated that the cost of reracking of the spent fuel ol serving Unit 1 and 2 will be S5,000 per fual assembly and the radiation dose to the iork force to be 150 man-ren.
The time required to rerack the basin!)l5 months, is greater than the k
tica remaining before the shortage of spent fuel stora.;e space at Oconee

impacts on production of electricity.
As a result of tha time required to perform this modificaticn, transshi: men'. :f fust assemblies to F.:Guire is not c
precluded.
At the predicted rate of dis:' arge, it e:culd still be n2cessary to transship approximately 250 assemblies to allow for the needed working space one year frca now.
A combination of rerac%ing plus the transshipment of 250 assemblies would be necessary.
Therefore,.:hile the alternative of reracking the spent fuel pool serving Units 1 and 2 is a viable cption, the time dalays involved may impact on power generation er result in greater impacts than the prcposed transshipment, e.g.,150 man-rem occupational exposure frca reracking plus additional exposure from transshippir.g approximately 250 fuel assemblies 53 EXHIBIT A
