  • Patent number: 4747995
    Abstract: An apparatus for the simultaneous shearing of two sides of the boiling water nuclear reactor control rod. The rotation of the rods at 90 degree rotation and the shearing of the second two sides underwater in a nuclear waste storage pool.In a previous application by A. H. Krieg, Ser. No. 692,849, we have seen the crushing of a BWR control rod for the purpose of reducing nuclear radioactive waste. The control rod however has an end referred to as the velocity limiter end, which is round and bulbous. This end can not be crushed practically, due to its mass. The purpose of this invention is to shear or cut-off the velocity limiter from the rest of the control rod thus having the remaining cruciform crushable. Between the velocity limiter and the rest of the control rod are 2 "D" shaped holes, hereafter refered to as the "D" holes. At this point the control rod is solid and does not contain hollow fins or boron rods.
