Transient thermal finite element analysis of CFC–Cu ITER monoblock using X-ray tomography data

Multi-scale CAFE Framework for Simulating Fracture in Heterogeneous Materials Implemented in Fortran Co-arrays and MPI

“…Previously ParaFEM has been used in large scale simulations in nuclear fusion research [20], [21] and bio-mechanics [22], [23].…”

The effect of carbon impurities on molybdenum surface morphology evolution under high-flux low-energy helium ion irradiation

“…3. Ex-situ XPS core level survey spectra for pristine, 1k eV Ar þ ion-sputter-cleaned additional pristine Mo sample (for reference and comparison purpose) and ion irradiated molybdenum surface having a gas mixture of He, CH 4 , and H 2 in the following ratios: He: CH 4 : H 2 : 100: 0: 0 for geting 100% He þ ions, 99.95: 0.05: 0 for getting 0.01% C þ ions, 99.75: 0.25: 0 for getting 0.05% C þ ions, 97.5: 2.5: 0 for getting 0.5% C þ ions, and 0:0: 100 for geting 100% H þ ions (XPS spectra not shown here). Ion energy (100 eV), ion fluence (2.6 Â 10 24 ions m À2 ) and target temperature (923 K) were kept constant for each experiment.…”

“…Until recently it was envisaged that the ITER divertor would include two tiers; the armor for lower and upper parts consisting of carbon fiber composites (CFC) and tungsten (W), respectively [4,5]. ITER and future fusion devices will use the hydrogen (H) isotopes, i.e., deuterium (D) and tritium (T), to fuel the fusion reaction.…”

Use of massively parallel computing to improve modelling accuracy within the nuclear sector

“…Investigations were made into various joining techniques for suitability of monoblock manufacturing considering cost vs quality of join. In work by Evans et al [55] IBFEM was used to investigate one candidate technique which managed to reduce manufacturing costs by using brazing for joining but also increased join quality by pre-coating 'off the shelf' commercially available brazing foils with chromium which serves to enhance bonding at the interface. A brief overview of that work is presented here as a case study to demonstrate how IBFEM can be used for modelling in nuclear engineering.…”
