Title: THE LEAD-GLASS VIEWING WINDOW IN THE PROCESSING REFABRICATION EXPERIMENT

Abstract

Design data and features incorporated in the all-glass radiation- shielding window designed for the proposed PRE facility and the techniques for servicing components of the window assembly are discussed. The PRE shielding window was designed so that all in-cell components can bc replaced by the in-cell crane. If necessary the lead-glass window can be replaccd from the operating gallery. An in-cell eover glass gasketed to the cell liner prevents a loss of cell atmosphere during the replacement operation. Auxiliary in-cell shielding would be used during window replacement. (auth)

  • A special in-cell maintenance workbench is required to aid in the remote maintenance of radioactive PRE in cell equipment. The development and demonstration of such a bench which rotates, moves in a vertical direction, is remotely operable, and has all in-cell components remotely maintainable, is outlined. (auth)
  • As part of the Processing Refabrication Experiment (PRE) a facility was designed to demonstrate the remote processing of short-cooled nuclear fuels which had been irradiated to power reactor levels. The Luminaire assembly, which was developed and operated as part of the PRE to meet these needs, consists of a 3-kw lamp located along the longitudinal axis of the parabolic surface of a reflector- type heat exchanger. The insulated electrical and coolant lines pass through a precisely surfaced through-roof conduit to the utility supply outside the cell. The throughroof conduit is tubular, filled with magnesia and steel shot shielding materials, andmore » sealed to the installation housing by a primary in-cell seal and secondary outof-cell seals. The conduit is supported by both an out-of-cell lock nut which also serves to compress the in-cell gasket-seal during lamp operations and extension rods suspended from an out-of-cell hoist during luminaire maintenance operation. The through-roof conduit, extension rods, and hoist perform ss a rigidarm crane to lower luminaire assemblies for in-cell maintenance. With the luminaire assembly replaced by a special hook attachment, items such as top-riding hoists, manipulators, and associated bridges could be lowered in the cell for maintenance. The technical oonsiderations affecting design and an evaluation of operational and maintenance procedures are presented. (auth)« less
  • A listing is presented of all dccuments concerning the Pyroprcoessing Refabrication Experiment (PRE), later renamed Processing Refabrication Experiment, from its inception as a project under AEC Contract AT(ll-1)-GEN8, General Order 7501, in June 1956, until its phase-out in July 1959. Also listed are documents released prior to the establishment of the Pyroprocessing Refabrication Experiment program at Atomics International that contain essential technical information upon whlch the PRE was based.

  • In the process proposed by the Processing Refabrication Experiment (PRE) as outlined various gases, fumes, and particulates are evolved during the melting operation and are carried off in a helium gas stream. The contaminants are removed from the carrier gas by either electrostatic or impingement filters and liquid metal or solid adsorbers. This project was undertaken to review the literature of adsorption of inert off-gases on silica gel, and to design, construct, and operate adsorption test equipment to ascertain the design parameters for a PRE pilot plant. (auth)
  • A review of progress in the PRE program is presented. It is pointed out that this program is a significant contribution to the concept of low- decontamination processing for irradiated nuclear fuels. In the mock-up program, equipment development progressed to the point where a facility for processing metallic uranium fuel may be designed which can be remotely operated and maintained. A study of equipment for processing UO/sub 2/ fuels was started and it is estimated that an additional year of research and development are required to design a facility for processing this material.
