  1. 1. A feasibility study of coolant void detection in a lead-cooled fast reactor using fission chambers

    Författare :Peter Wolniewicz; Nils Sandberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutron monitoring spectrum fast reactor fission chamber coolant void; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : One of the future reactor technologies defined by the Generation-IV International Forum (GIF) is the Lead-Cooled Fast Reactor (LFR). An advantage with this reactor technology is that steam production is accomplished by means of heat exchangers located within the primary reactor vessel, which decreases costs and increases operational safety.

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

    Författare :Peter Wolniewicz; Håkansson Ane; Christian Jammes; Uppsala universitet; []
    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.
