Nuclear data
Validation of the recently released International Reactor Dosimetry and Fusion File (IRDFF) in different fields
Evaluation of the 93Nb Reaction Cross-Section
Analysis of induced gamma activation by D-T neutrons in selected fusion reactor relevant materials with EAF-2010 and IRDFF-1.0
Dosimetry for research reactors
Older dosimetry data reviewing and documenting
Contribution of accelerator facilities to the reactor dosimetry
Extensive dosimetry demand of BNCT recognized
Advances in radiation heating measurements using calorimeters
Dosimetry for research reactors
Two main fields of calorimeters application: Electronics Fusion technology like energy deposition in
blanket, magnetic coil insulation, etc.
Neutron and gamma transport calculations and modelling
Focussed on methods coupling, implementation of core techniques
GEN 4 problems modelling: RPV damage Dose evaluations Tritium production
Neutron and gamma transport calculations and modelling
The Consortium for the Advanced Simulation of Light Water ReactorsLead by Oak Ridge National Lab and funded by U.S. Department of Energy, with participation from laboratory, academic, and industry partners Established in July 2010 for the purpose of providing advanced modeling and simulation solutions for commercial nuclear reactors. Primary goal is to provide coupled, higher-fidelity, usable modeling and simulation capabilities, needed to address light water reactor (LWR) operational and safety performance-defining phenomena that are not yet able to be fully modeled taking a first-principles approach.TITAN as main computing power (almost 300 000 cores and almost 19 000 GPU accelerators) and F-5 Storm as interface system (Joel A. Kulesza, et. al.)
