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.

    Recent measurements of neutron capture cross sections in the fission product mass region
    (OECD Nuclear Energy Agency, 1978) Musgrove, ARD; Allen, BJ; Boldeman, JW
    The radiative capture cross sections for the separated isotopes of Sr, Y, Zr, Mo, Pd, Cd, Ba, La, Ce, Pr and Nd in the energy range 3-200 keV were measured with high energy resolution at the 40 m station of the Oak Ridge Electron Linear Accelerator. Maxwellian average 30 keV cross sections and average resonance parameters derived from the analysis are tabulated. A strong dependence of the average radiative widths on neutron binding energy is noted. This leads to a pronounced even-odd disparity. Neutron strength functions reduce with decreasing binding energy along an isotopic owing chain to the decreasing density of doorway state at the binding energy.

    The fission neutron spectrum from the spontaneous fission of 252Cf
    (OECD Nuclear Energy Agency, 1978) Boldeman, JW; Culley, D; Cawley, RJ
    The fission neutron spectrum from the spontaneous fission of 252Cf has been measured using the time-of-flight method for the energy range 0.6 to 15 MeV. The spectrum was found to be very close to a Maxwellian distribution. In the region 1 to 6 MeV, deviations are less than 2%. Above 8.5 MeV, there is a significant but very small positive deviation from the Maxwellian shape which reaches approximately 15% between 10 and 14 MeV. The value found for the average energy of the Maxwellian is 2.110+-0.020 MeV.

    Resonance neutron capture in 23Na and 27Al from 3 to 600 keV
    (OECD Nuclear Energy Agency, 1978) Musgrove, ARD; Allen, BJ; Macklin, RL
    The radiative capture cross sections of 23Na and 27Al have been measured with the high resolution facility at the 40 m station of the Oak Ridge Electron Linear Accelerator. Resonance parameters for the individual resonance below 600 keV are given. Particular care was taken to correct the data for prompt neutron scattering effects by Monte Carlo methods.

    Materials separation via the matrix method employing energy-discriminating X-ray detection
    (MDPI, 2022-03-21) Yokhana, VSK; Arhatari, BD; Abbey, B
    The majority of lab-based X-ray sources are polychromatic and are not easily tunable, which can make the 3D quantitative analysis of multi-component samples challenging. The lack of effective materials separation when using conventional X-ray tube sources has motivated the development of a number of potential solutions including the application of dual-energy X-ray computed tomography (CT) as well as the use of X-ray filters. Here, we demonstrate the simultaneous decomposition of two low-density materials via inversion of the linear attenuation matrices using data from the energy-discriminating PiXirad detector. A key application for this method is soft-tissue differentiation which is widely used in biological and medical imaging. We assess the effectiveness of this approach using both simulation and experiment noting that none of the materials investigated here incorporate any contrast enhancing agents. By exploiting the energy discriminating properties of the detector, narrow energy bands are created resulting in multiple quasi-monochromatic images being formed using a broadband polychromatic source. Optimization of the key parameters for materials separation is first demonstrated in simulation followed by experimental validation using a phantom test sample in 2D and a small-animal model in 3D. © 2022 by the authors.

    A novel granular sludge-based and highly corrosion-resistant bio-concrete in sewers
    (Elsevier, 2021-10-15) Song, YO; Chetty, K; Garbe, U; Wei, J; Bu, H; O'moore, L; Li, X; Yuan, ZG; McCarthy, T; Jiang, GG
    Bio-concrete is known for its self-healing capacity although the corrosion resistance was not investigated previously. This study presents an innovative bio-concrete by mixing anaerobic granular sludge into concrete to mitigate sewer corrosion. The control concrete and bio-concrete (with granular sludge at 1% and 2% of the cement weight) were partially submerged in a corrosion chamber for 6 months, simulating the tidal-region corrosion in sewers. The corrosion rates of 1% and 2% bio-concrete were about 17.2% and 42.8% less than that of the control concrete, together with 14.6% and 35.0% less sulfide uptake rates, 15.3% and 55.6% less sulfate concentrations, and higher surface pH (up to 1.8 units). Gypsum and ettringite were major corrosion products but in smaller sizes on bio-concrete than that of control concrete. The total relative abundance of corrosion-causing microorganisms, i.e. sulfide-oxidizing bacteria, was significantly reduced on bio-concrete, while more sulfate-reducing bacteria (SRB) was detected. The corrosion-resistance of bio-concrete was mainly attributed to activities of SRB derived from the granular sludge, which supported the sulfur cycle between the aerobic and anaerobic corrosion sub-layers. This significantly reduced the net production of biogenic sulfuric acid and thus corrosion. The results suggested that the novel granular sludge-based bio-concrete provides a highly potential solution to reduce sewer corrosion. © 2021 Elsevier B.V.
