2.2 The cask surface should not be cleaned wi*.h steel wool or any other abrasive material.

2.3 The cask, yoke, and lif t adaptors should be thoroughly rinsed before they enter and emerge from the pool.

2.4 Refer to McGuire Limitations and Precautions (OP/0/A/6100/08) as applicable.

2. 5 When working near the edge of the Spent Fuel Pool insure compliance with all good safety practices. All tools and loose articles should be secured.

' 2.6 Because of the Overhead Fuel Handling Crane's lack of sensitivity in the North-South direction exercise care when operating the crane in the North-South direction.

i

OP/0/A/6550/13 PAGE 2 0F 4 2.7 The cask shall not be moved outside when a threat of severe weather disturbance exists.

2.8 The 125 ton crane main block and auxiliary hook should not be submerged in the spent fuel pool.

2.9 When operating the 125 ton crane main hoist with the " Fast" speed, do not run the hoist at anything less than the fastest speed for more than 15 seconds out of any minute to prevent overheating.

2.10 Do not allow weight of crane block to rest on the yoke, the adaptor storage bracket, or decon pit platforrr.

2.11 When operating the spent fuel pool manipulator crane bridge, gradually increase or decrease speed to move ir the North or Sduth di recti or,. Avoid sudden stops from full speec and starts to full speed to ensure the spent fuel is not subjecte: to any undue bending stresses.

2.12 When positioning the Spent Fuel Pool Manipulate- Crane, the manual handwheels may be used if the crane main power is first turned off.

2.13 Exercise caution when attaching quick disconnects to cask vents, to avoid being wetted by possible spray.

2.14 If work is to be suspended in the fuel building for more than two hours and the VF System is flowing through the filters, call the control room and have them open the bypass damcer. Ensure the bypass damper is closed before starting work again.

2.15 Each day that either the cask lif ting yoke, sh:rt lift adaptor, or long lift adaptor is used, the Lifting Device Caily Inspection must be conducted and documented on Enclosure 4.12.

OP/0/A/6550/13 PAGE 3 0F 4 2.16 B&W Spent Fuel Assemblies may be stored in Region 2 locations only.
