Abstract
A bottom open sled system for exchanging control rod drives in a nuclear reactor is described. The system, in one form, includes a tower forming a control rod drive receiving area, at least one acme screw extends substantially the length of the tower and is mounted within the receiving area. An elevator is coupled to the acme screw and is movable relative to the acme screw. The elevator is configured to engage a portion of the control rod drive and to substantially support the control rod drive. The system further includes a trunnion cart engaged to the tower so that the tower is rotatable relative thereto.
