  1. 1. Borehole heat store design optimization

    Författare :Bo Nordell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. LÄS MER

  4. 3. Production of photoneutron beams and radionuclides by photonuclear reactions using a 50 MeV racetrack microtron

    Författare :Bo Nordell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron therapy; Photoneutron spectrum; Bremsstrahlung; Angular distribution; Carbon 11; Iodine 123;

    Sammanfattning : The feasibility of using electrons accelerated by a 50 MeV racetrack microtron to generate a mixed beam of neutrons and photons for radiation therapy and for production of radionuclides has been investigated.To develop target systems for these purposes the angular distribution and yield of bremsstrahlung from different targets have been studied theoretically.

  5. 4. Secondary currents in groundwater

    Författare :Maria Engström; Bo Nordell; Anders Sellgren; Clifford Voss; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The thesis concerns the small vertical water movements created by thermal convection and the Coriolis force acting on groundwater flows. These small flows are of importance to vertical transports of temperature, nutrients and contaminants that would not be spread in the way they are. LÄS MER
