t 3.
Percove from the core and store the remaining 268 initial fuel elements
_l in the spent fuel pool.
Each time a fuel element is removed from
,I i
the core and stored fu the spent tuel pool a new fuel element will s
be placed in the vacant core thi cell to eilectuate a one-to-one fuel element interchange.
Strict adherence to the one-to-one fuel interchanre is not required for safety since any combination of 740 tuel elenents approved f or use at this tacility can be sately atored in tne spent fuel roof.
Af ter completion of refueline operations, there Vill Le no new tuel eierents stored in the new fuel vault or spent fuel storape pool, and i
there will be 484 irradiated fuel eierents stored in the snent fuel tool.
Ihe cpent tuel stvrape pool is uesicnea to accommoaate 740 tuel elements at iheir riost react ive exposure with an at tendant "ultiptication tactor of less than 0.90 dry or in the floodeu (noinborrico) t ater condition.
The new tuel storare vault is similarNv designed to store 150 new tuel elements with a nultiplication factor of less than u.90 dry and less than 0.95 in the f lood ed (non-borated) water condition.
Consequently, the pronosed number ot fuel eleuents that will be stored at a tir'e in either storace locations will not exceed the design capacit y cna vill rot result in an increased hazard or introuuce c uifterent
