  1. 1. Monte-Carlo response for mobile gamma spectroscopy in fallout affected residential areas

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : William Lindberg; [2021]
    Keywords : mobile gamma spectroscopy; SERPENT2; Monte-Carlo;

    Abstract : Historically, two nuclear power plant incidents have led to major releases of radioactive isotopes into the environment. In the unfortunate event that such an incident would occur in Sweden, the national emergency preparedness has set-up carborne detector systems which can be used to map radionuclides in fallout affected areas.

    Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE

  4. 3. Validation of the Westinghouse BWR nodal core simulator POLCA8 against Serpent2 reference results

    University essay from KTH/Fysik

    Author : Mathilde Gaillard; [2021]
    Keywords : Nodal Core Analysis; Monte Carlo Methods; CBH Effects; Nodal kärnanalys; Monte Carlo-metoder; CBH-effekter;

    Abstract : When a new nodal core simulator is developed, like all other simulators, it must go through an extensive verification and validation effort where, in the first stage, it will be tested against appropriate reference tools in various theoretical benchmark problems. The series of tests consist of comparing several geometries, from the simplest to the most complex, by simulating them with the nodal core simulator developed and with some higher order solver representing the reference solution, in this case on the Serpent2 Monte Carlo transport code.
