  2. 1. Neutronics in reactors with propagating perturbations

    Author : Anders Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; Molten Salt Reactors; two-group theory; neutron noise; propagating perturbations;

    Abstract : This thesis contains several studies of the properties of neutron noise, primarily in Molten Salt Reactors and other reactors with propagating perturbations. Both one- and two-group diffusion theory are employed to investigate the differences that arise from the movement of the fuel. READ MORE

  4. 2. Neutronics in Molten Salt Reactors

    Author : Anders Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; two-group theory; Molten Salt Reactors; neutron noise;

    Abstract : This thesis contains two studies of the MSR properties. The firstuses one-group theory and data that correspond to a traditionaluranium fuelled light water reactor to investigate the basis physicaldifferences that might arise duesolely to the movement of the fuel. READ MORE

  5. 3. Decision Making in Groups : Group membership effects on post-decision processes

    Author : Per Eisele; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; group membership.; social interaction style; group decision-making; decision strategy; Decision; post-decision processes; Psychology; Psykologi;

    Abstract : The present thesis examines differences in post-decision processes between members of groups and individual decision makers. The empirical studies employed a decision theoretical framework based on Differentiation and Consolidation (Diff Con) Theory. READ MORE

  6. 4. Noise Applications in Light Water Reactors with Traveling Perturbations

    Author : Victor Dykin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Green s function technique; transit times; decay ratio; cross-correlation function; void fraction; global and regional instabilities; propagating density perturbation; BWR stability; reduced order models; non-white driving force; local component; Monte Carlo; space-dependent neutron noise; density wave oscillations;

    Abstract : Neutron noise induced by perturbations traveling with the coolant of light water reactors (LWRs) is investigated. Different methods to simulate the effect of propagating perturbations are considered. The studies are performed in both open- and closed-loop systems and summarized in three chapters. READ MORE
