    The development and testing of Synroc C as a high level nuclear waste form
    (Cambridge University Press, 2011-02-15) Reeve, KD; Levins, DM; Ramm, EJ; Woolfrey, JL; Buykx, WJ
    The current status of SYNROC C research and development by the Australian Atomic Energy Commission is reviewed. A non-radioactive fabrication demonstration line designed to produce 10 cm o.d., 90 cm long, cylinders of SYNROC canned in stainless steel by the method of in-can hot pressing is being commissioned. Leach tests are proving the excellent leach resistance of SYNROC. Accelerated radiation damage testing using fast neutrons has simulated storage times of up to 6.7×105 years. Thermophysical properties of SYNROC have been measured over the temperature range 20–650°C. © Materials Research Society 1982

    The development and testing of SYNROC for high level radioactive waste fixation
    (Australian Atomic Energy Commission, 1981-02-23) Reeve, KD; Levins, DM; Ramm, RJ; Woolfrey, JL; Buykx, WJ; Ryan, RK; Champan, JF
    Research and development on the SYNROC concept for high level radioactive waste fixation commenced at the Australian Atomic Energy Commission Research Establishment, Lucas Heights, in March 1979, in collaboration with a complementary program at The Australian National University (ANU). The present paper reports progress in the project's second year and reviews its current status. An inactive 30 kg-scale SYNROC fabrication line incorporating in-can hot pressing as the fabrication step has been built for operation in mid-1981. Atmospheric pressure and hydrothermal leach tests are demonstrating the excellent leach resistance of SYNROC. Accelerated radiation damage tests using fast neutrons are simulating damage in SYNROC for periods of close to 10/sup 6/ years. In supporting research, mineral phase development, impact friability and thermophysical properties of SYNROC are being studied.

    Electron beam welding of stainless steels
    (International Institute of Welding, 1976-08-23) Chrimes, NWD; Gardner, RV
    A review is given of some of the principal problems encountered in the operation of a 30kV 500 mA electron beam unit installed at Lucas Heights in 1970. The principal welding parameters for the successful operation of a unit of this type are discussed, with particular emphasis on gun to work distance and vacua, and their effect on the weld properties.

    Some aspects of Australian research into citircal heat flux and post dryout phenomena
    (Hemispher Publishing Corporation, 1985-10-15) Green, WJ
    This paper provide a brief review of some aspects of the research investigations into boiling crisis and post crisis heat transfer which have been performed at the AAEC Research Laboratories using a pressurised Freon-12 heat transfer facility as the basic experimental tool. This paper also includes information on recent work being performed on rewetting phenomena as low mass fluxes.
