ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 8.3. The functionality has changed, but the content remains the same.

ANSTO Publications Online is a digital repository for publications authored by ANSTO staff since 2007. The Repository also contains ANSTO Publications, such as Reports and Promotional Material. ANSTO publications prior to 2007 continue to be added progressively as they are in identified in the library. ANSTO authors can be identified under a single point of entry within the database. The citation is as it appears on the item, even with incorrect spelling, which is marked by (sic) or with additional notes in the description field.

If items are only held in hardcopy in the ANSTO Library collection notes are being added to the item to identify the Dewey Call number: as DDC followed by the number.

APO will be integrated with the Research Information System which is currently being implemented at ANSTO. The flow on effect will be permission to publish, which should allow pre-prints and post prints to be added where content is locked behind a paywall. To determine which version can be added to APO authors should check Sherpa Romeo. ANSTO research is increasingly being published in open access due mainly to the Council of Australian University Librarians read and publish agreements, and some direct publisher agreements with our organisation. In addition, open access items are also facilitated through collaboration and open access agreements with overseas authors such as Plan S.

ANSTO authors are encouraged to use a CC-BY licence when publishing open access. Statistics have been returned to the database and are now visible to users to show item usage and where this usage is coming from.

    Hollandite ceramics: effect of composition on melting temperature
    (The American Ceramic Society, 2004-08-22) Carter, ML; Vance, ER; Casidy, DJ; Mitchell, DRG
    Hollandite-bearing (30-60 wt%) ceramic melts incorporating varying amounts of Cs2O (1.96-7.5 wt%) have been prepared in air by melting. Minor phases included zirconolite, perovskite and rutile. Detailed analysis of the phase assemblage of the samples by electron microscopy is presented on materials in which Fe, Co, Cr, Ni or Mn is targeted towards the B-site of the titanate hollandites, and the Cs in the hollandite A-site. Mn, Ni and Co entered the hollandite as divalent species while Fe and Cr in the hollandite were trivalent. DTA measurements showed that the melting temperatures of the differently substituted hollandite-rich ceramic melts varied between 1315 and 1450°C. The effect on melt temperature and phase assemblage of substituting K for Ba in the hollandite structure of the melts was also examined. © The American Ceramic Society

    A brief guide to the Australian Atomic Energy Commission research establishment
    (Land Printing House, 1956) Australian Atomic Energy Commission
    In September, 1954, the Commission submitted plans for the creation of an atomic energy research and development organisation in Australia. Commonwealth Government approval of this plan paved the way for the building of the A.A.E.C. Research Establishment at Lucas Heights, on the fringe of the metropolitan area, 20 miles south of Sydney. The initial program, which has now been completed, provided for the construction of a high flux research reactor, laboratories and workshops for research into nuclear energy. Staff for the Research Establishment, now numbering more than 800, were recruited mainly in Australia. Research teams have kept abreast of current developments overseas by means of staff postings to atomic energy establishments in countries with which Australia has exchange agreements. The building program on the 160-acre site involved construction of: • a heavy water moderated research reactor known as HIFAR (High Flux Australian Reactor) with a maximum flux of neutrons per sq. cm. per second and a maximum heat output of 10,000 kilowatts; • a low power graphite/light water moderated reactor known as MOATA, with a maximum flux of 1 0 11 neutrons per sq. cm. per second and a maximum heat output of 10 kilowatts; • laboratories for research in chemistry, chemical engineering, health physics, radiation biology, reactor physics, technical physics, isotopes, metallurgy and engineering; • library; • gatehouse, garages, stores, boiler house, effluent treatment plant and control laboratory, and laundry and decontamination centre; • administrative buildings. The work of the Research Establishment is carried out by joint teams of scientists and technologists organised into sections, each under its own head, and with defined research activities. For administrative purposes the Research Establishment is divided broadly into two main groups, one dealing with research activities and the other with service and operational activities.

    The effect of aging on feopolymers made from fly ash and matakolinite
    (Institute of Materials Engineering, Australasia Ltd, 2004-11-29) Perera, DS; Nicholson, CL; Fletcher, RA; Cassidy, DJ; Aly, Z; Finnie, KS; Vance, ER
    Geopolymers are formed by adding Si and Al generally in reactive glassy or fine grained phases to concentrated alkali solutions for dissolution and subsequent polymerisation to take place. We made geopolymers using fly ash or metakaolinite produced by heating kaolinite at 750°C for 15 h as Si and Al sources. Geopolymer pastes aged for between 1 day and 2 years after curing were investigated in this study. We characterised the materials by electron microscopy, x-ray diffraction analysis (XRD), differential thermal analysis/thermogravimetric analysis (DTA/TGA). BET surface area, infra-red spectroscopy and solid state nuclear magnetic resonance (NMR). Their density and porosity were determined by several methods Both types of geopolymers were predominantly amorphous and there were no changes in the minor crystalline phases with ageing as shown by XRD. The geopolymers made from fly ash showed significant differences in porosity and surface area with ageing. 27Al and 298i NMR indicated that the on-going reactions within the geopolymer matrix are contributing to these changes after the material has set and hardened. The DTA/TGA and density/porosity for the geopolymer made from metakaolinite did not show any significant changes. The differences between the two types of geopolymers will be discussed with respect to ageing.

    An analytic model for drag reduction in turbulent flow when polymers are present
    (University of Newcastle, 1983-11-28) Beattie, DRH
    A model is proposed for drag reduction by polymer additives. The model assumes (a) intermittency between polymer—coil agglomerates in the near—wall region; (b) extension of polymer coils in regions where turbulent energy production exceeds a threshold level; (c) a uniform layer of polymer coils on the wall side of the layer of extended polymers ; and (d) a shift of the origin of the logarithmic velocity profile equation from the wall to the wall side of this layer of uniform polymer coils. The model, and predictions based on it, are shown to be compatible with several observed drag reduction phenomena.

    An extension of single phase flow turbulent pipe flow concepts to two-phase flow
    (UNSW Faculty Engineering, 1983) Beattie, DRH
    This thesis describes a series of investigations into the hydraulic and thermal characteristics of various turbulent two-phase pipe flows, arising from one particular way of extending to two-phase flow, concepts previously developed for single phase pipe flow, e.g. mixing length, turbulent core, wall boundary or sub-layer, roughness, Reynolds analogy, etc. This approach predicted a logarithmic core profile of local volumetric flux as a function of wall distance. Accounting for a range of different possible sub-layer fluid structures, it led to a dimensionless profile, and hence directly to a wall friction factor, in terms of dimensionless parameters chosen according to the type of sub-layer. A 'friction regime' concept was developed, with regimes classified by sub-layer type and two characteristic integers which serve to determine the profile. The relations developed were based on the analysis of world-wide experimental two-phase flow data, and a number of practically useful new friction factor correlations resulted. For a number of different 'friction regimes', the work was supplemented by additional models and analyses and applied to the prediction of average void fraction, heat transfer coefficient, critical heat flux, pulse propagation velocity and choked flow rate. In many cases, significant agreement was achieved between predictions and published data for which simultaneous measurements of several parameters guaranteed experimental consistency.
