    LUBRA - a code to calculate point and group cross sections, effective resonance integrals and doppler coefficients for reasonable absorbers in homogeneous reactors, using Breit-Wigner single-level resonance parameters.
    (Australian Atomic Energy Commission, 1966-10) Kletzmayr, EK
    The LUBRA complex of codes is designed to produce (i) point cross sections, (ii) infinitely dilute resonance integrals, (iii) effective resonance integrals based on the different approximations presently available and optionally modified to include particle size effects, (iv) Doppler coefficients, also based on the various models, and (v) group averaged cross sections, using Breit-Wigner single—level resonance parameters and other basic data only. The complex currently comprises five individual programmes coded in FORTRAN IV for an IBM 7040 computer and linked together by a specialised monitor system to permit the use of LUBRA as a single entity.

    MULGA - a complex of codes for the determination of multigroup averaged neutron cross section data
    (Australian Atomic Energy Commission, 1963-12) Clancy, BE; Doherty, G; Keane, A; Kletzmayr, EK; Pollard, JP
    A complex of computer programmes called MULGA is described which will produce multigroup cross sections in a format suitable for input into a selection of reactor codes. Always bearing in mind that the spatial variation of flux will frustrate any determination of "exact" cross sections the maximum accuracy has been striven for within the limitations of urgency and feasibility. The programmes; together with an associated microscopic data library tape, and a specialised monitor system, have been coded for an IBM 1620 computer with 4 magnetic tapes. The basic programmes MULGA 1 and MULGA 2 have already been adapted for an ISM 7090 and the whole series will be modified for the new site computer in 1964.

    A study of the effective resonance integral and doppler coefficients of U238, Th232, and Pu240 using the code complex LUBRA
    (Australian Atomic Energy Commission., 1966-12) Keane, A; Kletzmayr, EK
    The effective resonance integral and Doppler coefficient of U238, Th232, and Pu240 have been studied in detail using the LUBRA complex of codes. Some earlier results were used for comparison to verify the validity of the LUBRA results discrepancies have been explained and confidence can be placed in the results given by the LUBRA codes.
