  2. 1. Gamma Spectrometric Measurements Of Nuclear Material For Nuclear Forensic Purposes

    Author : Anna Vesterlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear forensics; americium; signatures; uranium; gamma spectrometry; abundance;

    Abstract : Nuclear forensics is a scientific discipline that aims to aid in criminal investigations concerning illicit use of nuclear and other radioactive material. The discipline aims to find signatures within the nuclear material that can help to find the attribution, or the origin and intended use of the seized material. READ MORE

  4. 2. Microstructure Evolution and Mechanical Properties of Haynes 282

    Author : Ceena Joseph; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Abstract : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. READ MORE

  5. 3. Mechanical Properties of Gamma Titanium Aluminides

    Author : Viktor Recina; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; intermetallic compound; tensile properties; diffusion bonding; sample preparation; low cycle fatigue; fractography; gamma titanium aluminide; mechanical properties;

    Abstract : In recent years intermetallic compounds have attracted a great deal of attention as structural materials. Among the intermetallics, gamma titanium aluminides (.gamma.-TiAl) are considered to be closest to application. READ MORE

  6. 4. METHOD DEVELOPMENT FOR SIGNATURES IN NUCLEAR MATERIAL FOR NUCLEAR FORENSIC PURPOSES

    Author : Anna Vesterlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Uranium; Nuclear forensics; Lanthanide patterns; ICP-MS; gamma spectrometry; 241Am;

    Abstract : Nuclear forensics is a scientific discipline where signatures in nuclear and other radioactive material are investigated and evaluated in order to aid in criminal investigations concerning these materials. Examples of signatures that may be useful is the age and isotopic composition of the nuclear material and trace elements in the material. READ MORE

  7. 5. Applications of Gamma Ray Spectroscopy of Spent Nuclear Fuel for Safeguards and Encapsulation

    Author : Christofer Willman; Ane Håkansson; Henrik Nylén; Uppsala universitet; []
    Keywords : Nuclear physics; gamma radiation; spectroscopy; spent nuclear fuel; safeguards; HRGS; MOX; Kärnfysik;

    Abstract : Nuclear energy is currently one of the world’s main sources of electricity. Closely connected to the use of nuclear energy are important issues such as the nonproliferation of fissile material that may potentially used in nuclear weapons (safeguards), and the management of the highly radioactive nuclear waste.
