The present invention is drawn to an incremental link robot mast for vacuuming nuclear waste from a storage silo. The mast is made of incrementally linked segments that are clamshell in construction to enclose and shield the working cables of the vacuuming robot. Each segment is linked together as needed by a transverse hinge pin and two hydraulic connecting pins. The clamshell is hinged and latched together by an array of screws. The robot comprises a linked clamshell mast and a master-slave robot arm on the end of the mast which includes tools for viewing and breaking up the waste and vacuuming same to a removal area.

A sludge lance wand for cleaning once through steam generator tubes. A curved high pressure fluid feed tube has a plurality of feed tube extensions attached at one end and a first nozzle brace attached at the other end and in fluid communication with the feed tube. A second nozzle brace bolted to the first nozzle brace retains nozzle blocks in position between the two braces. The nozzle blocks are in fluid communication with the first nozzle brace and are provided with nozzle openings angled for cleaning the triangular-pitch positioned tubes in a once through steam generator. O-ring seals on each end of the nozzle blocks press fit against the braces to prevent leakage and insure that full fluid flow is directed through the nozzle openings.
