boxes.
They are all locally fusion welded together without the local raised coined areas.
A poison assembly is inserted and locked into each of the narrow rectangular boxes.
Region 1 pitch is 10.95" as shown in Figure 2.5.
g. C - 10(Sl80 2.1.1 HYDRODYNAMIC COUPLING 1
All racks are installed with:a 1" gap, rack-to-rack, because the very strong hydrodynamic coupling, forces the racks to move together even when considering adjacent racks, one full and the next one empty.
The water in the rack - rack gap acts to force the racks in line to move in unison.
If two racks are modeled they would be coupled to each other in the same manner the fuel is coupled to the racks,1.e., using hydrodynamic masses 3
Based on Case #13 from Fritz (Ref. 03) MH " ph b/12S (where h & b are rack face dimensions, S is the gap and p is the 6
density of water),
a 1" gap results in MH = 2.62x10 pounds.
Rack to wall gaps are used to assess the hydrodynamic coupling between the rack array and pool walls.
I 2.2 MATilEMATICAL COMPUTER MODEL Initially Region 2 racks had 6 levels of box fusion welds.
The computer analysis was performed using 6 lumped masses for the rack, which represented 6 box fusion weld locations.
This was changed to 8 levels of box fusion welds.
To simulate this effect a computer test model was developed, using 8 lumped masses for the 132-call rack.
Loads for the test run were obtained from Section 6.0, consolidated fuel, EAST-WEST SSE condition because EAST-WEST SSE loads are higher than the NORTH-SOUTH SSE loads.
