SOUTH TEXAS ERQJECT SPENT FUEL SMRAGE RACKS BACE liANDLIMG AND INSTALLATION INSTRUCTIONS 1.0 BACE liANDLING On-site handling consists of removal of a rack horizontally from the shipping truck, upending to vertical, and vertical lifting. The necessary 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 each for Region 1 and Region 2, Figures 1 through 6, are included here, showing rack handling and equipment.- These were reduced from drawings 8709-46, Region 1 and 8709-47, Region 2.

1.0.1 Horizontal lift is accomplished with a pair of nylon I 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 tuil length into storage cells which have a bayonet slot jn the bottom plate. The top ends of the adapters are pinned to the ends of a pair of spreader bars to which is attached a four-leg sling hung on the lifting crane hook. The pair of syrer. der bars ptcvide the required lift redundancy in accord-ance with NUREG-0612.

2.0 INSTALLATION There are three phases of rack installation. These phases are defined below:

Phase I (Unit 2 only) - Region 1 racks (6 racks) installed to store new fuel dry (Ref. dwg 8709-59).

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 8709-60).

Phase III (Units 1 and 2) - Region 1 and 2 wet spent fuel and consolidated fuel storage, full pool (Ref.

, dwg. 8709-1).

2.1 EllASE I 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.

Level the rack to i 1/16 inch.

2.1.2 Place Rack #2 (dwg. 8709-3) in the pool, dimensionally spaced from the west wall and Rack #1 as ohown on the plan arrangement for Phase I rack installation (dwg.

8709-59). Place Rack #3 (dwg. 3709-4) in the pool, dimensionally spaced from the north wall and Rack #1; place Rack #4 (dwg. 8709-5) in the pool, dimensionally spaced from Rack #2 and Rack #3; place Rack #5 (dwg.

8709-6) in the pool, dimensionally spaced from the north wall and Rack #3; and place Rack #6 (dwg.8709-7) in the pool, lidensionally spaced from Rack #4 and Rack #5 as shown on the plan arrangement for Phase I rack installation (dwg. 8709-59).

For Rack #5 and Rack #6 confirm that the minimum ,

dimensions from the east wall are met. Racks #2,

13, 14, #5, and 16 shall be leveled as described in Section 2.1.1.

2.2 PJi&SE 11 INSTALTATION 2.2.1 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 II rack installation (dwg.

8709-60). This placement will be accomplished by measuring or using gage blocks if available. Level the rack, if the installation is dry, or diver assisted if wet, by using a six to eight foot long spirit level across the top of the rack. Leveling 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. Level the rack to i 1/16".

2.2.2 Place Rack #2 (dwg. 8709-3) alongsjde Rack #1 and dimensionally spaced from Rack 11 and the west wall as i required on the plan arrangement for Phase II rack installation (dwg. 8709-60). All racks shall be  :

installed with a minimum 1" rack-to-rack gap. The l maximum rack-to-rack gap shall not exceed 1.25" as  !

noted on (dwg. 8709-60). Place Rack #3 (dwg. 8709-4) alongside Rack #1 at the same dimension from the north wall. Place Rack #4 (dwg. 8709-5) alongside Rack #3 and #2. Place Rack #5 (dwg. 8709-6) alongside Rack #3 and at the same dimension from the north wall. Place Rack 16 (dwg. 8709-7) alongside Rack 15 and #4. Level each rack as it is installed as described in Section 2.2.1. The south face line-up of Racks #2, 14 and #6 shall be porpondicular to the west wall. The north face lino-up of Racks fl, 13 and #5 shall be parallel to the north wall.

2.2.3 Place Rack #7 (dwg. 8709-8) alongside east face of Rack #5 and dimensionally spaced from the north wall as shown on the plan arrangement for Phase II rack l installation (dwg. 8709-60). Place Rack #8 (dwg. I 8709-9) alongside the south face of Rack #7. Line-up l the cast face of Rack #8 with the east face of Rack

  1. 7. In sequence, install Racks #9, #10, #11 (dwgs.

8709-10, -11, -12, respectively), with the previously installed rack south face. The east face of these five racks are to be in-line and parallel to the east
