  1. 16. Welding of dissimilar metals in different welding positions

    University essay from KTH/Materialvetenskap

    Author : Mimmi Bäck; [2016]
    Keywords : ;

    Abstract : The three boiling water reactors (BWR) in Oskarshamn produce about 10 % of the electrical power in Sweden. The combination of intense radiation fluxes and high temperatures in nuclear reactors creates an extraordinary environment. READ MORE

  4. 18. Tomographic reconstruction of subchannel void measurements of nuclear fuel geometries

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Magnus Ahnesjö; [2015]
    Keywords : tomography; void; nucler power; bwr;

    Abstract : The Westinghouse FRIGG loop in Västerås, Sweden, has been used to study the distribution of steam in the coolant flow of nuclear fuel elements, which is known as the void distribution. For this purpose, electrically heated mock-ups of a quarter BWR fuel bundles in the SVEA-96 geometry were studied by means of gamma tomography in the late 1990s. READ MORE

  5. 19. Validation and Benchmarking of Westinghouse BWR lattice physics methods

    University essay from KTH/Reaktorteknologi

    Author : Karol Luszczek; [2015]
    Keywords : Serpent; HELIOS; lattice physics; benchmarking; Monte Carlo; neutronics; reactor physics;

    Abstract : A lattice physics code is a vital tool, forming a base of reactor coreanalysis. It enables the neutronic properties of the fuel assembly to becalculated and generates a proper set of data to be used by a 3-D full coresimulator. READ MORE

  6. 20. Control Rod Effect at Partial SCRAM : Upgrade of Plant Model for Forsmark 2 in BISON After Power Uprate

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Daniel Constanda; [2015]
    Keywords : nuclear power; bwr; boiling water reactor; BISON; POLCA; partial SCRAM modeling; control rod effect; transients;

    Abstract : This study aims to improve the modeling of partial SCRAM in the BISON plant model for the Forsmark 2 nuclear reactor after power uprate. Validation of the BISON model against tests performed from March to May in 2013 have shown that this is one of the areas in which there is room for improvement. READ MORE
