1.

All dimensions are design nominal values. Maximum and minimum dimensions are specified to bound variations in design nominal values among fuel assemblies within a given array/class.

2.

This assembly is known as QUAD+. It has four rectangular water cross segments dividing the assembly into four quadrants.

3.

For the SPC 9x9-5 fuel assembly, each fuel rod must meet either the 9x9E or the 9x9F set of limits or clad O.D., clad I.D., and pellet diameter.

4.

This assembly class contains 74 total rods; 66 full length rods and 8 partial length rods.

5.

Square, replacing nine fuel rods.

6.

Variable.

7.

This assembly contains 92 total fuel rods; 78 full length rods and 14 partial length rods.

8.

This assembly class contains 91 total fuel rods; 83 full length rods and 8 partial length rods.

9.

One diamond-shaped water rod replacing the four center fuel rods and four rectangular water rods dividing the assembly into four quadrants.

10.

These rods may also be sealed at both ends and contain ZR material in lieu of water.

11.

Not used.

12.

When loading fuel assemblies classified as DAMAGED FUEL, all assemblies in the MPC are limited to 4.0 wt.% U-235.

13.

When loading fuel assemblies classified as DAMAGED FUEL, all assemblies in the MPC are limited to 4.6 wt.% U-235.

14.

In accordance with the definition of UNDAMAGED FUEL, certain assemblies may be limited to 3.3 wt.% U-235. When loading these fuel assemblies, all assemblies in the MPC are limited to 3.3 wt.% U-235.

15.

These fuel designs do not have water rods, but instead contain solid zirc rods.

16.

Any number of fuel rods in an assembly can be replaced by irradiated or unirradiated Steel or Zirconia rods. If the rods are irradiated, the site specific dose and dose rate analyses performed under 10 CFR 72.212 should include considerations for the presence of such rods.

17.

Any number of fuel rods in an assembly can be contain BLEU fuel. If the BLEU rods are present, the site specific dose and dose rate analyses performed under 10 CFR 72.212 should include considerations for the presence of such rods.

18.

Contains in total 91 fuel rods; 79 full length rods, 12 long partial length rods, and one square water rod replacing 9 fuel rods.

19.

Contains in total 96 fuel rods; 80 full length rods, 8 long partial length rods, 8 short partial length rods and one water rod replacing 4 or 12 fuel rods.

20.

Contains in total 112 fuel rods; 92 full length rods, 8 long partial length rods, 12 short partial length rods, and one square water rod replacing 9 fuel rods.

21.

This is the maximum fixed rod pitch. The assembly may have areas of variable pitch that exceed this value and remains acceptable for storage.
