ABSTRACT:
Spent control rods from nuclear reactors are prepared for disposal by cutting off their handle ends and their velocity limiter ends by a cut off saw positioned in a pit underwater. The saw is driven by an air motor which is controlled outside the pit and has its exhaust carried up out of the water through a conduit. The control rods so truncated are packed into shielded casks for transport while the handle ends and velocity limiter ends are left in the pit or alternatively are loaded into separate shielded containers.
