  1. 16. Sensitivity study of control rod depletion coefficients

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Joel Blomberg; [2015]
    Keywords : nuclear power; control rod; control rods; depletion; kärnkraft; styrstav; styrstavar; utbränning;

    Abstract : This report investigates the sensitivity of the control rod depletion coefficients, Sg, to different input parameters and how this affects the accumulated 10B depletion, β. Currently the coefficients are generated with PHOENIX4, but the geometries can be more accurately simulated in McScram. READ MORE

  3. 17. Optimization of RIA-calculations : Simulating Falling Control Rods at Forsmark Nuclear Power Plant

    University essay from Institutionen för fysik och astronomi

    Author : Christian Alex; [2013]
    Keywords : nuclear physics; safety analysis; control rod;

    Abstract : This report accounts for investigations of ways to reduce the calculation times forsimulations of falling control rods in boiling water reactors done prior to everyreactor startup, known as RIA-calculations. Two methodologies to lower thecalculation times have been proposed, developed and implemented in a set ofmatlab-scripts, which are fully compatible with the previously used methodology. READ MORE

  4. 18. Control rod drop during hot zero power : RIA in BWR

    University essay from Tillämpad kärnfysik

    Author : Malin Fritz; [2013]
    Keywords : Control rod; RIA; BWR;

    Abstract : During operation of nuclear power reactors reactivity initiated accidents (RIA) can occur, such as a control rod drop. If this occurs, the reactivity increase dramatically and leads to an increase in power, fuel enthalpy and fuel temperature. The fuel and reactor can be damaged. READ MORE

  5. 19. Topology Optimization of Vehicle Body Structure for Improved Ride & Handling

    University essay from Maskinkonstruktion; Mekanik

    Author : Sebastian Lövgren; Emil Norberg; [2011]
    Keywords : topology optimization; size optimization; compliance; design space; volfrac; Volvo cars; body structure; body stiffness; struts; beams; bolted components; Altair; hyperworks; hypermesh; optistruct; stepwise optimization; early design phase; benchmarking;

    Abstract : Ride and handling are important areas for safety and improved vehicle control during driving. To meet the demands on ride and handling a number of measures can be taken. This master thesis work has focused on the early design phase. At the early phases of design, the level of details is low and the design freedom is big. READ MORE

  6. 20. Growth and Characterization of ZnO Nanostructures

    University essay from Institutionen för fysik, kemi och biologi

    Author : Abdul Samad Syed; [2011]
    Keywords : PL photoluminescence ; Zinc Oxide ZnO ; optical properties; temperature dependent PL; Low temperature PL; Nanostructure; epitaxial film;

    Abstract : A close relation between structural and optical properties of any semiconductor material does exist. An adequate knowledge and understanding of this relationship is necessary for fabrication of devices with desired optical properties. READ MORE
