    The Australian high temperature gas-cooled reactor research project
    (Australian Atomic Energy Commission, 1964-07) Alder, KF; Roberts, WH
    A brief history is given of activities at the Lucas Heights Research Establishment, and the reasons that led up to the selection of beryllium oxide for investigation as a promising moderator material in high temperature gas—cooled reactor systems. The choice of a pebble—bed core for an initial design study of an actual reactor is discussed; the results to date and an outline of the future programme are presented.

    The design and construction of HIFAR
    (Melbourne University Press on behalf of The Australian Atomic Energy Commission, 1958-06-02) Roberts, WH
    A brief description is given of the design and construction Commission's of the Australian Atomic Energy reactor HIFAR, located near Sydney or Lucas Heights. The design is based on that of the British DIDO, a high flux, heavy water moderated and cooled reactor having a maximum thermal neutron flux of 1014 neutrons/sq. cm/sec., and a maximum heat output of l0 megawatts.

    Some major design parameters for the H.T.G.C. reactor project
    (Australian Atomic Energy Commission., 1958-10) Roberts, WH
    (a) Based on economic considerations approximate estimates of various H.T.G.C.R. parameters have been made. The Paper is not an exhaustive design study but does endeavour to determine reasonable starting points. Values of these parameters prove to be: Maximum Gas Temperature = 500ºC - 600ºC Minimum Gas Temperature = about 250ºC Fuel Burn Up = 100% - 150% (with fissile material at £5,000/Kg). = 2005 - 250% (with fissile material at £20,000/Kg). Gas Pressure Ratio = 1.10 - 1.25 (b) There are two regions of maximum gas temperature in which it might be worthwhile to concentrate, namely, 500ºC - 600ºC with steam turbines or 800ºC(+) with gas turbines. It appears questionable that temperatures between these two regions should be considered unless the installed cost per KW of the two types of installation are significantly different.
