Design Features 4.0 4.0 DESIGN FEATURES 4.1 Site Location The McGuire Nuclear Station site is located at latitude 35 degrees, 25 minutes, 59 seconds north and longitude 80 degrees, 56 minutes, 55 seconds west. The Universal Transverse Mercator Grid Coordinates are E 504, 669, 256, and N 3, 920, 870, 471.
The site Is in northwestern Mecklenburg County, North Carolina, 17 miles north-northwest of Charlotte, North Carolina.
4.2 Reactor Core 4.2.1 Fuel Assemblies The reactor shall contain 193 fuel assemblies. Each assembly shall consist of a matrix of either ZIRLOTC or Zrcalloy fuel rods with an Initial composition of natural or slightly enriched uranium dioxide (UO 2) as fuel material. Umited substitutions of ZIRLOC, 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 fuel 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 53 control rod assemblies. The control material shall be silver Indium cadmium (Unit 1) silver Indium cadmium and boron carbide (Unit 2) as approved by the NRC.
4.3 Fuel Storage I
I 4.3.1 Criticality 4.3.1.1 The spent fuel storage racks are designed and shall be maintained with:
- a.
Fuel assemblies having a maximum nominal U-235 enrichment of 4.75 weight percent;
- b.
keff < 1.0 If fully flooded with unborated water, which Includes an allowance for uncertainties as described in Section 9.1 of the UFSAR;
- c.
kiff < 0.95 if fully flooded with water borated to 850 ppm, which Includes an allowance for uncertainties as described In Section 9.1 of the UFSAR; McGuire Units I and 2 4.0-1 Amendment Nos. 222 & 204
