  1. 1. Investigation on Operation of the Compact Molten Salt Reactor by Modelling the Primary Circuit in GeN-FOAM

    University essay from KTH/Fysik

    Author : Jelle Oving; [2022]
    Keywords : molten salt reactor; GeN-Foam; delayed neutrons; OpenFOAM; multi-physics; smältsaltreaktor; GeN-Foam; fördröjda neutroner; OpenFOAM; multifysik;

    Abstract : In recent years there has been a revision of the molten salt nuclear reactor concept for production of power. Moving of fissile material throughout the primary circuit for these types of reactors creates the necessity of novel physics solvers to study movement of delayed neutron precursors, plant operation, accident scenario's; crucial for design.

  3. 2. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Westlund; [2019]
    Keywords : bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Abstract : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. READ MORE

  4. 3. Compaction of Lattice Data : Improved Efficiency in Nuclear Core Calculation

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

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

    Abstract : 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.

  5. 4. Nuclear reactor core model for the advancednuclear fuel cycle simulator FANCSEE. Advanceduse of Monte Carlo methods in nuclear reactorcalculations

    University essay from

    Author : Alexander Skwarcan-Bidakowski; [2017]
    Keywords : Nuclear; Reactor; Physics; simulation; FANCSEE; Serpent; energy; neutron; cross; section; Bateman; atom; isotope; fission; reaction; uranium; plutonium; capture; physics; power; calculation; burnup; Kärnkraft; Reaktor; Kärna; Simulering; FANCSEE; uran; pluton; Serpent; energi; atom; isotop; fisson; Bateman;

    Abstract : A detailed reactor core modeling of the LOVIISA-2 PWR and FORSMARK-3BWR was performed in the Serpent 2 Continuous Energy Monte-Carlocode.Both models of the reactors were completed but the approximations ofthe atomic densities of nuclides present in the core differedsignificantly.

  6. 5. Analysis of the neutron albedo’s influence on TIP deviations in Forsmark 1

    University essay from

    Author : Moa Skan; [2016]
    Keywords : ;

    Abstract : In the operation of a nuclear reactor, detailed calculations are performed to predict the power distribution in the core and to ensure the maintenance of a number of safety margins. Repeatedly during a power cycle, the predictions are verified in so-called TIP measurements, and the consequences of possible deviations are investigated. READ MORE
