"ATTACHMENT ST.HL AE Mn PAGE S OF 6 SOUTH TEXAS PROJECT SPENT EUEL STORAGE RACKS EAC3 HANDLING AND INSTALLATION INSTRUCTIONS 1.0 RACK HANDLING On-site handling consists of renoval of a rack horizontally from the shipping truck, upending to vertical, and vertical lifting.
The necessary i
equipment will be shipped with the first rack.
The maximum estimated weight of the heaviest rack is not more than 15 tons.
Three reduced size drawings are included here, showing rack handling and equipment for UST&D racks on another project.
The same type of drawings will be furnished for the South Texas racks, i.e. 8709-46, Region 1 and 8709-47, Region 2.
1.0.1 Horizontal lift is accomplished with a pair of nylon straps slung around the rack and attached to a spreader bar.
The spreader bar is rigged with a two-leg sling hung on the lifting crane hook.
1.0.2 Upending is accomplished by using two of four vertical lifting adapters and attaching them to a pair of cables hung from a spreader bar.
The spreader bar is rigged to a two-leg sling hung on the upending crane hook at the top end of the rack.
Two brackets are bolted through bottom plates at the bottom end of the rack.
The horizontal lift nylon straps are looped through these brackets and hung on a second crane hook which provides stability as the top end is raised.
If the second crane hook is not available the upending operation can be accomplished by carefully rolling the rack about its bottom edge using the crane at the top end.
1.0.3 Vertical lift is accomplished by using the four ver-tical lifting adapters which have a bayonet end at the bottom and extend full length into storage cells which have a bayonet slot in the bottom plate.
The top ends of the adapters are pinned to rotatable ends of a pair i
of spreader bars to which is attached a four-leg sling j
hung on the lifting crane hook.
The pair of spreader j
bars provide the required lift redundancy in accord-ance with NUREG-0612.

2.0 INSTALLATION There are three phases of rack installation.
These i
phases are defined below:
Phase I (Unit 2 only) - Region 1 racks (6 racks) installed to store new fuel dry (Ref. Dwg 8709-59, Rev. 0)
Phase II (Units 1 and 2) - Region 1 and 2 wet spent fuel and consolidated fuel storage without a three rack row at the south end of the spent fuel pool (Ref.
Dwg 8709-40, Rev. 0)
Phase III (Units 1 and 2) - Region 1 and 2 wet spent fuel and consolidated fuel storage, full pool (Ref.
Dwg. 8709-1, Rev. 1) 2.1 PHASE 1 INSTALLATION 2.1.1 Place Rack #1 (dwg. 8709-2) in the pool, dimensionally spaced from the north and west walls as shown on the plan arrangement for Phase I rack installation (dwg.
8709-59).
Level the rack by using a six to eight foot long spirit level across the top of the rack.
Leve-ling requires that the rack be lifted clear off the floor while using the pedestal adjusting screw tool down through the appropriate cell over the screw.

J1 AGE ? OF 3 PEDESTAL FORCES The maximum forces on one pedestal for the seismic disturbances are for the 132 cell rack. The following values are SRSS values taken from Table 6.4, Set #4:
Vertical (Lbs)
Horizontal (Lbs)
OBE 263265 84039 SSE 441129 141937 MOVEMENT AT BASE The maximum values for other outputs from Table G.4, Set e5 are:
SSE Elastic Displacement:
0.5609 in. 132-cell rack east west Sliding Displacement:
0.9638 in. 132-cell rack north south Lift off:
0.1310 in. 132-cell rack east west OBE Elastic Displacement:
0.3494 in. 112 cell rack east west Sliding Displacement: 0.1803 in. 132 cell rack north south Lift off:
0.0 in. 132-cell rack east west and north south ALILVABLE DISPIACEMENT The maximum displacement, 6, consisting of the rack displac) ment associated with five OBE events plus one SSE event was calculated.
The total calculated displacement is 5 (0.1803) inches + 1(0.9638) inches - 1.8653 inches.
calculated maximum displacement (1.8653 inches) is less than the 1.64 inches minimum rack to wall gap provided at the north end o t e pool, the minimum separation i
between the pool and the rack (Figure 3 1).
I d DRY STORACE LL Tabulated results for dry storage of new fuel in the Region 1 spent j
fuel storage rack seismic analysis are grouped and identified by "Sets" numbered 1 through 5 as shown on Table 6.5.
6.6.2.4.2 Mechanical Analysis of Rack Structural Adequacy for Seismic Loads Stresses in the internal rack welds are computed due to both deadweight and seismic loads.
Seismic loads are the maximum reac-tions from Seismic Analysis, Section 6.6, for a Region 2,132 cell rack.
Seismic stresses are calculated using the SRSS method and are cothined with the submerged weight stresses.
