The exclusion area boundary shall have a radius of 696 meters from the centerline of the reactor.
4.2 Reactor Core 4.2.1 Fuel Assemblies The reactor shall contain 800 fuel assemblies.
Each assembly shall consist of a matrix of Zircaloy or ZIRLO clad fuel rods with an initial composition of natural or slightly enriched uranium dioxide (U0 2 ) as fuel material, and water rods.
Limited substitutions of zirconium alloy or stainless steel filler rods for fuel rods, in accordance with approved applications of fuel rod configurations, may be used.
Fuel assemblies shall be limited to those fuel designs that have been analyzed with applicable NRC staff approved codes and methods and shown by tests-or analyses to comply with all safety design bases.
A limited number of lead test assemblies that have not completed representative testing may be placed in nonlimiting core regions.
4.2.2 Control Rod Assemblies The reactor core shall contain 193 cruciform shaped control rod assemblies.
The control material shall be boron carbide or hafnium metal, or both.
4.3 Fuel Storage 4.3.1 Criticality 4.3.1.1 The spent fuel storage racks are designed and shall be maintained with:
- a.
- 0.95 if fully flooded with unborated water, which includes an allowance for uncertainties as described in Section 9.1.2 of the UFSAR;
