  1. 11. Compaction of Lattice Data : Improved Efficiency in Nuclear Core Calculation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Hanna Lundgren; [2017]
    Nyckelord :nuclear physics; nuclear core calculation; PHOENIX; POLCA; Westinghouse; cross sections;

    Sammanfattning : Westinghouse Electric Sweden AB’s three-dimensional reactor core simulation program POLCA uses a large number of tables containing various fuel dependent data, such as cross sections, pin power maps with power distribution etc. POLCA uses quadratic and linear interpolation to extract the values needed for the simulation.

  3. 12. BWR In-Core Instrumentation Sensitivity to Material and Geometrical Distortions

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mikael Nivala Fernberg; [2016]
    Nyckelord :;

    Sammanfattning : Several BWR utilities are adopting practices for determining the state of control rods based on the neutron sensitive LPRM and gamma sensitive TIP measurement systems of the nuclear reactor core. This method is in this study evaluated by quantitatively analyzing the detector sensitivity to several material and geometrical distortions in the detector vicinity, using the Los Alamos National Laboratory stochastic Monte Carlo code MCNP5 and the Westinghouse 3D core simulator POLCA7.

  4. 13. Development of the endurance test program and the assembly fixture for TRITON11™

    Master-uppsats, Lunds universitet/Innovation

    Författare :William Lundström; [2016]
    Nyckelord :Nuclear fuel; Boiling Water Reactor; fretting wear; test program; assembly fixture; Technology and Engineering;

    Sammanfattning : The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. LÄS MER

  5. 14. Qualification of WestinghouseBWR lattice physics methods againstcritical experiments

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Kim Landelius; [2016]
    Nyckelord :HELIOS; PHOENIX5; lattice code;

    Sammanfattning : This thesis is part of a larger qualification effortperformed at Westinghouse Electric Sweden AB of the PHOENIX5 latticephysics code. The aim of the thesis is to validate PHOENIX5 withregards to cold criticality tests performed at the Toshiba NCAfacility in 2010-2011. LÄS MER

  7. 15. Utveckling av snabbfäste och verktyg för byte av sågklinga

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Fredrik Höök; Albin Odevik; [2015]
    Nyckelord :CAD; Snabbfäste; Sågklinga; Konstruktion; Koncept; Klingbytesverktyg;

    Sammanfattning : This thesis is based upon the work done at Westinghouse electric company (WEC)in Västerås during the spring semester of 2015 and describes the development of a quick coupler with associated blade changing tool. These are meant to be used together with a sawing tool that the company uses for the dismantling of nuclear reactors, which is performed under water. LÄS MER
