There are two fuel assemblies in each container and a maximum of seven shipping containers loaded on each truck.
The fuel assemblies will be unloaded one at a time f rom their containers in the fuel storage building. At that time they will be inspected for shipping damage and then stored in the new fuel vault or spent fuel pool fuel storage racks.
l The empty containers will eventually be loaded onto trucks for return shipment.
Detailed dimensional checks of the fuel assembly and components are per- {
formed at the Westinghouse fuel f acility prior to shipping. The intent of the dimensional checks performed in this procedure is to verify that no gross damage has,been sustained as a result of shipping.

NOTE: 11 hen using a r.nerry picker to unload a container it is per-missible to set the container down near the truck and then transfer the container to the designated storage area using the forklift.
8.1.11.6 Set the container down on a level surf ace and then disconnect the lifting harness and guide rope.
CAUTION: Do not stack containers more than two high.
NOTE: It may be necessary to use blocking or shims to level a container which is being stored outside.
8.1.11.7 Repeat step 8.1.11.2 through 8.1.11.6 for the remaining containers as appropriate depending on the unloading device.
8.2 Preparation of shipping containers for saw fuel assembly unloading.
8.2.1 Place the shipping container in the designated upending area as determined by Reactor Engineering.
Be sure that the container is sitting level. l 8.2.2 Visually inspect the exterior of the container for the items listed in Part 1 of RS 0722B. Record the serial numbers of the seals wired through the container flange along with the container identification.
Verify that the serial numbers agree with the shipping papers. Break and remove the seals.
8.2.3 Remove the two wingnuts and the round cover plate over the air valve at the af t end of the container. Equali container pressure with atmospheric pressure by pres-sing or removing the air valve core (see Figure 10.2).
Reinsert the air valve core if it has been removed then replace the cover plate and the two wingnuts. I 8.2.4 Loosen the fastener hardware between the container shell halves. If the container is equipped with bolts, simply unfasten. Note any loose bolts on RS 0722B, Part 1.

1 l RS 0722 Page 11 l- Rev. 03 8.2.5 Attach the 4 point lif ting sling to the lif ting lugs on the container lid.
NOTE: All lif ting will be done using the cask handling crane auxiliary hooks.
8.2.6 Slowly raise the cover approximately 2 or 3 inches and verify separation of the cover f rom the container. Do not attempt to reposition the gasket seal at this time.
CAUTION: DO NOT place hands or fingers between the cover and container sections.
8.2.7 Raise the cover an additional 3 feet (approximately) in order to clear the container internals. If the gasket seal has been misaligned during cover removal, reposition the gasket seal on the bottom container half. Move the container cover to a suitable lay-down area with wooden cribbing.
8.2.8 H.P. shall conduct a smear analysis of the polyethy-lene bags and container interior surf aces. If the bags or interior is contaminated, clean them until the smear analysis limits are met. Record the results on RS 0722B, Part 2.
8.2.9 Visually inspect the interior of the container for the items listed in Part 2 of RS 0722B. Record the details of any anomalous condition observed and resolve them with the on-site Westinghouse Representative.
NOTE: If either of the two limit-type accelerometers are tripped, as indicated by any balls and springs being dislodged from their seats, the fuel may have experienced acceleration in excess of design limitatiers. The Westinghouse on-site or fuel projects representative should be contacted.
NOTE: Check the two visible sides of the polyethylene bag for tears, abrasions, indentations and s c ra tche s . RS 0722D can be used to help locate these areas during fuel assembly inspection.
Be sure to carefully inspect the underlying areas of the fuel assembly where any of these items are found.
8.2.10 Position the outrigger members located on the outside of the container assembly as shown in Figute 10.2.
Lock in place using the hardware provided. Only the outrigger members located on the side are required.
Use of the front outriggers (if installed) is optional. Adjust the pads as required to obtain firm contact with the floor but do not attempt to level the container with these members, they are oniv for stabilization.
RS 0722 Page 12 Rev. 03 8.2.11- Remove the ball lock pin . securing the lateral lock tubes at the aft end of the shock mount frame, see Figure 10.3. It will be necessary to lift the inter-nals te permit telescoping the lock tubes into their pockets. This may be accomplished in either of two ways.
- a. Crane lift by the lif ting fixtures provided in the vicinity of the bottom support. Some containers have a lift ring attached to each axle pillow block while others have rings on the bottom sup-port base. Crane lifting requires the two-legged sling with shackles.
or
- b. A small hydraulic jack may be used to jack against the underside of the bottom support. A piece of wood approximately 2 x 6 x 6 inches must be placed underneath the jack to prevent bending the con-tainer with the jack base.
Secure the lock tubes in position by tightening the screws on the lock tube pockets located on the container l shell.
8.2.12 Using a long extension such that rachet clears- the -
fuel assembly, loosen the swing bolt clamps of the shock nount frame and swing the clamps free of the fuel assembly support frame. See Figures 10.2 and 10.3.
8.2.13 Completely back off the hold down pad screws on the top closure assemblies. Remove the ball lock pins securing the top closure assemblies and swing the assemblies open as far as possible. Loosen the top of the polyethylene bag if necessary and enter the fuel assembly number and the core component (if any) number on RS 0722B.
8.2.14 Loosen the nuts on the side pad jacking screw except those on the top and bottom clamping frames, see Fig. 10.3.
8.2.15 Loosen, but do not unfasten, each of the clamping frame fastener nuts except those on the top and bottom clamping frames. Do not open the clamps at this time.
8.2.16 Unf asten the tape along the length of the polyethylene bag sleeve being careful not to puncture or tear the sleeve.
8.2.17 Attach the crane to the lifting eye at the forward end of the fuel assembly support frame. This cperation requires the short steel sling and shackle.
RS 0722 Page 13 Rev. 03 8.2.18 Verify top and bottom clamping frames are secure.
CAUTION: All personnel should be clear of shipping container before up-righting the support f rame.
8.2.19 Pivot the support f rame slowly to the vertical posi-tion. Coordinate crane movement in the vertical direction with crane movement in the horizontal in steps small enough to maintain approximate vertical alignment of the cable. Be sure not to lift the con-tainer off the floor. See Figure 10.4. l 8.2.20 While holding support f rame in the vertical position, install the supports and secure with hardware pro-vided. See Figure 10.5. The crane should not be removed from the lifting eye until the uprighted sup-port f rame is secured.
8.2.21 Remove the crane hook from the lifting eye.
8.3 Unloading a new fuel assembly from the container 8.3.1 Assemble the new fuel assembly handling tool and nylon sling onto the cask handling crane aux. hook, and position the tool above the exposed fuel assembly nozzle. A load cell with rating >, 2000 lbs may be included between the aux. hook and the new fuel "
- handling tool.
8.3.2 Guide the new fuel assembly handling tool onto the exposed nozzle. Insure the crane hook is centered above the fuel assembly. Lock the tool in position and take up the slack (if using a load cell take up a load less than 250 lbs) in the lif ting sling.
NOTE: See Figure 10.6 for handling tool instructions.
CAUTION: Do not lif t the fuel assembly or container.
8.3.3 While maintaining tension on the sling and the i assembly, finish loosening and swing open all but the top and bottom clamping f rames.
8.3.4 Loosen and open the bottom clamping f rame and then loosen and open the top clamping frame.
8.3.5 Swing back all clamping frames and adjust clamping f rame hardware as necessary to provide a f ree removal path.
I It is very important that the clamping f rame CAUTION:
hardware be clear of the fuel assembly during removal. Fuel assembly damage could result if these frames contact the assembly l [
during movement.
RS 0722 Page 14 Rev. 03 8.3.6 The fuel assembly may now be removed f rom the shipping container.
NOTE: As a general guide, lift the fuel assembly up a few inches to clear the lower half of the con-tainer then slowly jog out the assembly to clear the swing clamps.
8.3.7 Inspect the polyethylene bag for tears, abrasions, indentations and scratches. Record any findings on j RS 0722D by marking where such damage is located with ;1 respect to the fuel assembly.
8.3.8 Unf asten the polyethylene bag at both ends being care-ful not to puncture or tear the bag. Remove the bag, using caution to prevent the bag from tearing on the spacer grids.
8.3.9 Conduct a smear test of the fuel assembly af ter the polyethylene bag is removed. A minimum of 4 swipes must be taken per assembly.
CAUTION: Fuel Assemblies placed in the New Fuel Storage Vault shall only_ be placed in the locations indicated on Form RS 0720G of the SNM Inventory and Control Procedure.
8.3.10 Move the fuel assembly to the designated fuel inspec-
. tion area or storage location. Documentation of fuel moves are performed in accordance with RS 0720, SNM Inventory and Control.
8.3.11 If the fuel assembly is being stored directly without being inspected, center the fuel assembly over the storage cell. Orient tne assembly such that the reference hole is in the couth east location and the Y corner is in the southwest location. Slowly insert it until it is seated on the bottom. Remove the handling tool. See Precaution 5.20.
8.3.12 Close the fuel assembly clamping f rames on the con-tainer for the position in which unloading was just completed. Tighten the clamping f rame fr stener nuts. l 8.4 New Fuel Assembly Inspection NOTE: Record all results of step 8.4 on RS 0722C and use RS 0722D in conjunction with RS 0722C to locate dif-ficiencies on the fuel assembly.
8.4.1 Visually check the fuel assembly for any gross bowing or twisting.
4 RS 0722 Page 15 Rev. 03 8.4.2 Perform a dimensional check of the bottom nozzle by visually checking for signs of warping or damag .
Verify nozzle holes .are smooth and spaced at an approximate center to center distance of.9.5 inches.
8.4.3 Perform the following visual inspection of the fuel assembly. .If the fuel. assembly is to be inspected during insertion into a storage cell, center the assembly over the cell. Orient the assembly such that the reference hole is in the south east location and the Y corner is in the south west location. Then slowly insert it. See Precaution 5.20.
8.4.3.1 Remove all foreign deb.fis such as polyethylene fragments, dirt, paint chips-and metal shavings.
8.4.3.2 Perform a dimensional check of the rod spacing by visually checking the space between bottom of fuel rods and the top of the bottom nozzle. There must be no con-tact between the fuel rod and plugs and the bottom nozzle. In addition, the full diameter of the end plugs must extend below the lower plane of the first grid strap.
8.4.3.3 Inspect for loose fuel rods.
8.4.3.4 Carefully inspect areas where the fuel l rods and grid straps come into contact.
Insure that there hss not been any wear on the fuel rod due to vibration type action against the grid straps.
8.4.3.5 Inspect for broken, cracked or missing brazed joints.
8.4.3.6 Inspect for sharp edges which break the l continuity of the spacer grid perimeter l strips.
8.4.3.7 Inspect for local surface defects such as i dents, cracks, scratches, deep pits and sharp-edged burrs.
NOTE: During the final assembly of the fuel bundle, fuel rods may have sustained numerous shallow scratches (less than 0.001 inch) and small burnish marks. Do not re: ord these conditions unless they seem excessive in depth.
l
RS 0722 Page 16 Rev. 03 8.4.3.8 Remove all grease,and stains.
NOTE: During cleaning operations with solvent and distilled water, the f uel assembly surf aces may have become stained with " water marks",
a slight darkening of the zircaloy metal. While these conditions are cosmetically unappealing, they do not degrade the specified quality of the assembly, ,
1 8.4.3.9 Inspect to ensure there is no visually I discernable decrease or increase in chan-nel spacing between fuel rods. All rods should be spaced approximately 1/4 inch f rom each other.
8.4.4 Perform a dimensional check of the rod spacing by visually checking the space between top of the fuel rods and the bottom of the top nozzle. There must be i no contact between the fuel rod and plugs and the top 1 nozzle. In addition, the full diameter of the end l plugs must extend above the upper plane of the last grid strap.
8.4.5 If the fuel assembly is not already in the desired storage location transfer it there then center the f uel assembly over the cell. Orient the assembly such that the ref erence hole is in the south east location and the Y corner is in the south west location.
Slowly insert it until it is seated on the bottom.
See Precaution 5.20.
8.4.6 Remove the new fuel handling tool.
8.4.7 Perform a dimensional check of the top nozzle by verifying that the new fuel handling tool operated properly and no binding was encountered while latching or unlatching the fuel assembly.
NOTE: It is not necessary to perform section 8.4.8 while the fuel assembly is in the new fuel vault. RE Department personnel may defer per-formance of all or portions of section 8.4.8 until af ter the fuel assembly is transferred to the spent fuel pool.
8.4.8 Perform a dimensional check of guide tubes and a visual inspection of core components as follows.
8.4.8.1 Perform a dimensional check of the guide tubes by lif tin- the core component slightly to vertfy that the core component is not bound within the guide tubes.
1 I
RS 0722 Page 17 Rev. 03 8.4.8.2 Perform core component receipt and inspec-tion using RS 0724, Core Component Receipt and Inspection (Section 8.3).
8.4.9 If any fuel assemblies are judged unacceptable for use in the reactor, a nonconf ormance report (Form AQ 14.003A), must be filled out. l 8.5 Closure of Container 8.5.1 Swing the two top closure assemblies closed and secure locking pins. Ensure all clamping f rames and hardware are closed and tightened.
8.5.2 Attach the crane to the shipping container support f rame lif ting eye, using the single legged steel sling and shackle, and remove the slack f rom the sling.
E.5.3 Remove the locking pins securing the supports to the s.pport frame. Move the supports to their storage position and secure them.
8.5.4 Carefully pivot the support frame from the vertical to a horizontal rest position in the container shock mount frame.
8.5.5 Loosen the screws on the lock tube pockets. Retract the lock tubes, lif ting the internals as before if necessary. Fasten the lock tubes in the retracted position by installing the ball lock pin.
8.5.6 Engage and tighten at least one swing bolt near the l top on each side of the support frame in order to clamp the fuel assembly support f rame to the s; ock mount frame.
8.5.7 Return outrigger members to their storage position and install the locking pins. Account for all hardware which may have dropped or been taken f rom the con-tainer.
8.5.8 Install the container cover. asing the 4-point Cing connected to the crane hook. The serial number should be at the aft end for proper orientation of the cover.
When installing the lid make sure that the gasket is properly seated. Containers equipped with 1/4 turn Camloc fasteners should have the cover lowered to within ih inch of the bottom and each stud checked to ascure that it is not cocked with the weight of the lid on it. As in unfastening, each Camloc stud can be f astened by turning 90* with a wrench.
8.5.9 Remove the Department of Transportation (DOT) radioac-tive shipment label and attach an " EMPTY" label.
l RS 0722 Page 18 Rev. 03 8.5.10 Move the closed container, using the overhead crane, a forklift or cherry picker, to the designated storage location for eventual loading onto a truck.
1 8.6 Return of Empty Shipping Containers. l 8.6.1 Position the truck in the fuel storage building railway access area or near the outside storage area as necessary.
8.6.2 Using the 4-point harness attached to the cask handling crane auxiliary hook or a cherry picker or using a forklift, replace the empty containers on the t bed of the truck in the same pattern they were received. (i.e. 3 front and 4 near, etc.)
NOTE: If needed, nail wood blocks to the vehicle bed along the containers skids to prevent movement of the container.
8.6.3 Fasten the containers to the bed of the vehicle by cables or chains passed over the containers at both f orward and af t ends. Cables or chains shall be ten-sioned with binders or other suitable means. Rigging should conform to Ref. 2.8.
8.6.4 Insure that all required paperwork (bill of lading, etc.) is coepleted for release of the shipment.
9.0 FINAL CONDITIONS 9.1 All fuel assemblies have been unloaded f rom the shipping con-tainer and are stored in the new fuel storage racks or the spent fuel storage racks and the protective cover is in place.
9.2 The shipping container has been closed and moved to a storage location or is ready to be or has been loaded on the truck.

FIGURE 10.6 New Fuel Assembly Handling Tool Operatinc Instructions
- 1. Suspend the tool f rom the overhead crane using a basket hitch with the nylon sling.
- 2. Center the teol above the fuel assembly to be lif ted.
Note: Check that the safety screw on the side. of the tool is turned out and the operating handles are in the UP position.
- 3. Slowly lower the tool and guide the two locating pins into the holes in the fuel assembly top nozzle.
- 4. When the tool has bottomed on the fuel assembly, move the operating handles to the DORN position and turn the saf ety screw IN. The fuel assembly is now ready to be lif ted and moved to another location.
NOTE: When lif ting the tool out of the fuel assembly, it is very important that the cable supporting the tool is directly in line with the fuel assembly. This will prevent any possible '
binding of the locating pins.
- 5. When the fuel assembly is transf erred to its new location, it is lowered, and then released by turning OUT the saf ety screw and moving the operating handles to the UP position.
