  2. 1. 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

    Keywords : ;

    Abstract : 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. READ MORE

  5. 3. Nuclear data uncertainty quantification and data assimilation for a lead-cooled fast reactor : Using integral experiments for improved accuracy

    Author : Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Oscar Cabellos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Total Monte Carlo; ELECTRA; nuclear data; uncertainty propagation; integral experiments; nuclear data adjustment; uncertainty reduction;

    Abstract : For the successful deployment of advanced nuclear systems and optimization of current reactor designs, high quality nuclear data are required. Before nuclear data can be used in applications they must first be evaluated, tested and validated against a set of integral experiments, and then converted into formats usable for applications.

  6. 4. Experimental and theoretical studies of nitride fuels

    Author : Merja Pukari; Janne Wallenius; Toru Ogawa; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fast reactor fuel; ab-initio modelling; fuel fabrication; inert matrix nitride fuel;

    Abstract : With respect to nitrides being considered as potential fast reactor fuels, research is conducted on the out-of-pile thermophysical properties, sintering and fabrication processes, gas migration mechanisms, self-diffusion and point defect behaviour of actinide nitrides, their surrogate materials, and the inert matrix material ZrN . The experimental research, carried out in the framework of qualifying fuel for the European Lead Cooled Training Reactor (ELECTRA), shows that sintered ZrN and (Dy,Zr)N pellet densities are influenced by the oxygen concentration in the material.

  7. 5. Nuclear data uncertainty propagation for a lead-cooled fast reactor: Combining TMC with criticality benchmarks for improved accuracy

    Author : Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Christophe Demaziere; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad kärnfysik; Applied Nuclear Physics;

    Abstract : For the successful deployment of advanced nuclear systems and for optimization of current reactor designs, high quality and accurate nuclear data are required. Before nuclear data can be used in applications, they are first evaluated, benchmarked against integral experiments and then converted into formats usable for applications. READ MORE
