On Assuet 30, 1973, we met with your representative and Babcack & Wilcox staff members to discuss your proposed special loading procedures for these portions of your initial fuel load for Rancho Seco which contain restatered yellate. At that meeting, we indicated the conceptual eseeptability of your proposal but stated that we would need additional information to conclude our evaluation of this matter. The additiemal information we require is listed in the encleeure to this letter. ' Ia' i
order to e==e1=de our reviser la an. orderly fashima with consideraties' 1
