    Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER

  2. 2. Transmutation of Americium in Fast Neutron Facilities

    Detta är en avhandling från Stockholm : KTH Royal Insitute of Technology

    Författare :Youpeng Zhang; KTH.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; americium; transmutation; fast reactor; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik Kärnfysik; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In this thesis, the feasibility to use a medium sized sodium cooled fast reactor fully loaded with MOX fuel for efficient transmutation of americium is investigated by simulating the safety performance of a BN600-type fast reactor loaded with different fractions of americium in the fuel, using the safety parameters obtained with the SERPENT Monte Carlo code.The focus is on americium mainly due to its long-term contribution to the radiotoxicity of spent nuclear fuel and its deterioration on core's safety parameters.

  3. 3. Neutronics and Transient Analysis of a Small Fast Reactor Cooled with Natural Circulation of Lead ELECTRA: European Lead Cooled Training Reactor

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Erdenechimeg Suvdantsetseg; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis, neutronics and some relevant transient analyses of the European Lead-Cooled Training Reactor (ELECTRA) are analyzed. ELECTRA is a low-power lead-cooled fast reactor intended for training purpose. The design concept aims for the total nominal power of 0. LÄS MER

  4. 4. Development of a Methodology for Detecting Coolant Void in Lead-cooled Fast Reactors by Means of Neutron Measurements

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Peter Wolniewicz; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LFR; fission chamber; nuclear; reactor; leak; criticality;

    Sammanfattning : In a lead-cooled fast reactor (LFR), small bubbles (in the order of one mm or less) may enter the coolant from a leaking steam generator. If such a leakage is undetected the small bubbles may eventually coalesce into a larger bubble in local stagnation zones under the active core.
