Keel Mass Removal

Yesterday Randy and I removed the 4 Keel mass stacks from BSC2. A swivel lifting eye was used to gently lift until the mass stack seperated from the viton pads. Once seperated the viton was placed in a foil pouch. Each stack was wrapped in foil and craned onto a pallet. The last stack was wrapped with the pouch of viton. The swivel lifting eye was bagged and placed on top of the pallet of masses for use when the masses get added back onto the ISI.

The lifting pads, bumax hardware, and lifting fixture hardware plus SEI tools are staged on the table below the stairs to the garb room.
