FUSE meeting notes: 17 Jan 2022

[orso82]

• Orso:
  • Working with Julia Hub to
    • get installation to work with private package registry
    • review how we handle data structure in FUSE
  • TAUENN in MATLAB to avoid using any of FUSE source as part of ALF SciDAC
• Jackson: New BOP code. Comes with example and awesome plotting!
  • What level of fidelity? Circulator power for each circuit assuming some pressure drop that are input to the actor.
  • Can we add additional cooling paths? Is it modular? Can but not as modular, need to think how to feed the inputs nicely. Different designs can support two or four cooling loops. The code would work.
  • Needs to be reviewed and merged. Need to open PR on IMASDD.
  • Costing model associated with it?
  • Engaging with FLUOR
• Tim
  • Working to get optimizations to work
  • R, delta, k, Ip, Bt, magnet material, bucking,...
  • Fixed issue with negative triangularity in EPEDNN
  • There is an issue with handling of divertor region, which is not too robust depending on equilibrium
  • Installed CHEASE on SAGA
  • Dave: Steady state operation is a key metric
• Adriana
  • Expose polarized fuel fraction as input simulation parameter
  • Brian: important because it can help (ITER and FPP), and can releave other parts of the design
  • UCI is testing this as reality in DIII-D
  • 10% reactivity increase may be
• Brendan
  • Gantt chart translated into GitHub milestones
  • Tricky because we have multiple repos, so need to create same milestones on different repositories
  • Can now sort issues across different repos based on milestones
• Tyler
  • Will work on summary of analytic MHD limits next week
• Luke
  • Now busy with FIDASIM and IMAS. Will get back to FUSE soon.
  • MXHEquilibrium.jl should be drop-in replacement of Equilibrium.jl
• Kevin
  • We have a way to deterministically solve 1D neutronics problem
  • Takes 10 to 15 seconds (it's mostly runtime, 3 to 6 layers)
  • Validated with OpenMC
  • Also built a data library for CX data for different materials (in Python now but easy to port to our Julia package)
• Tom
  • Parsed TGLF datasets in a single database for training
  • Symmetric effect of VExB_shear
  • VPAR effect is very small --> remove it? --> Should have an effect on ITER, where VEXB_SHEAR is low.
• Nan
  • Trying to get closer to original GASC scenario
  • Stable scenario achieved --> can share it
    • 500 MW fusion
    • comparable to APS case, but lower plasma current
    • 45MW of Paux
• Discussion
  • AI/ML call in support of FPP
    • Expand EPEDNN on negative triangularity
    • TGLFNN in negative triangularity is more critical
