Spent Fuel Assembly Storage 3.7.17 Figure 3.7.17-1 Allowable Storage Arrays Array A Two Region 1 assemblies (1) checkerboarded with two blocked cells (X). The Region 1 assemblies are each in a cell with an L-insert. No NETCO-SNAP-IN inserts are credited.

X 1
Array B Two Region 1 assemblies (1) checkerboarded with two cells containing trash cans (TC). The Region 1 assemblies are each in a cell with an L-insert. Every cell without an L-insert must contain a NETCO-SNAP-IN insert.
1 TC TC 1
Array C Two Region 2 assemblies (2) checkerboarded with one Region 3 assembly (3) and one blocked cell (X). The Region 2 assemblies are each in a cell with an L-insert. The Region 3 assembly is in a cell containing a NETCO-SNAP-IN insert.

Array D One Region 2 assembly (2) checkerboarded with three Region 4 assemblies (4). The Region 2 assembly and the diagonally located Region 4 assembly are each in a storage cell with an L-insert. The two storage cells without an L-insert contain a NETCO-SNAP-IN insert.

Notes:
- 1. The shaded locations indicate cells which contain an L-insert.
- 2. A blocked cell (X) contains a blocking device and only water in the active fuel region.
- 3. NETCO-SNAP-IN inserts must be oriented in the same direction as L-inserts.
- 4. NETCO-SNAP-IN inserts are only located in cells without L-inserts.
- 5. Any cell containing fuel or a TC may instead be an empty (water-filled) cell in all storage arrays.
- 6. Any storage array location designated for a fuel assembly may be replaced with non-fissile material.
