SUPPLEMENTAL TESTIMONY OF JOEL E. KOHLER CN CONTENTION 2(f)(2)
Ca May 1,1979, the Board issued an order which, among other things, denied the NkJ Staff motion for sumary disposition of Contention 2(f)(2).
This testimony addresses the followino partion of the factual issue which the Board stated remained for consideration with recard to Centention 2(f)(2):
The possible increased crobability and cotential consecuence of accidental damage to scent fuel assemblies as a result of cossible slidina or tinoing of the fuel storage racks during installation and fuel assembly transfers.
Sliding or tipoing of new fuel racks during installation shculd be prevenced cy the olanned utili:nicn of a lifting ric to raise and icwer the rack.
The li# ting ric encloses :ne fuel rack and contains fcur evelets or contact 0
ccints, accroximately 30 a ca rt, tnrcugn wqic, li#tinc cables wculd ce run.
Tne rac<, correctly ricged, will ce lifted vertical'.v during mcvement. Hanc-
'eid guice. vires will be used to insure that tne racks do not rotate.

-2 The fuel racks sit on embedments, whicn are part of the liner. The emoty weight of one rack is approximately 40,000 pounds.
Since this weight far outweighs the weight of one fuel assembly (1,9C0 counds), and since the fuel racks have feet, tipping of the fuel rack during transfer is not possible.
In conclusion, the use of a lifting rig and guide wire' to assure procer align-ment, as well as the empty weight of the fuel rack, should prevent sliding or tioping of fuel racks during installation and fuel transfer.
