  2. 1. Experimental analysis of thermal mixing at reactor conditions

    Author : Mattia Bergagio; Henryk Anglart; Paolo Vinai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing estimator; empirical mode decomposition; Hilbert-Huang transform; uncertainty assessment; radial heat flux; Energy Technology; Energiteknik; Fysik; Physics;

    Abstract : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. READ MORE

  4. 2. Sensitivity and Uncertainty Analysis of BWR Stability

    Author : Ivan Gajev; Tomas Lefvert; Paolo Vinai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; Engineering physics; Teknisk fysik; SRA - Energy; SRA - Energi;

    Abstract : Best Estimate codes are used for licensing, but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

  6. 4. Development of Effective Algorithm for Coupled Thermal-Hydraulics – Neutron-Kinetics Analysis of Reactivity Transient

    Author : Joanna Peltonen; Tomas Lefvert; Paolo Vinai; KTH; []
    Keywords : Light Water Reactor; BWR; RELAP5; PARCS; Coupling TH NK; Mapping; Spatial Refinement; Turbine Trip; Feedwater Transient; Control Rod Drop; Reactor Stability;

    Abstract : Analyses of nuclear reactor safety have increasingly required coupling of full three dimensional neutron kinetics (NK) core models with system transient thermal-hydraulics (TH) codes. To produce results within a reasonable computing time, the coupled codes use different spatial description of the reactor core. READ MORE

  7. 5. Design studies of ELECTRA : European Lead-Cooled Training Reactor

    Author : Erdenechimeg Suvdantsetseg; Janne Wallenius; Paolo Vinai; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SRA - Energy; SRA - Energi;

    Abstract : A fast neutron research reactor with heavy metal coolant is of interest for Generation IV reactor system develop- ers. In this thesis, the European Lead-Cooled Training Reactor (ELECTRA), which is a low-power lead-cooled fast reactor intended for training purposes, is analyzed. The main aim of the design is that the total nominal power of 0. READ MORE
