Project Summary
The objective of this project is to develop an integrated computational model linking the materials physics scale with the component-level scale to simulate the thermomechanical response of the full first wall/blanket structures during fusion reactor operation. Phenomena of interest at the three modeling scales include:
- Fundamental properties (“Level 1”)
- Transmutant inventory changes
- Dose- and material chemistry-dependent PKA energy distributions
- Displacement cascades in isotopically-changing environments
- Chemical environment-dependent defect structures
- Irradiation defect distributions
- Tritium transport/trapping in chemically evolving environments
- Microstructural evolution (“Level 2”)
- Irradiation hardening, creep, and swelling
- Grain growth/recrystallization
- Tritium permeation and retention
- Component evaluation (“Level 3”)
- Integrated thermomechanical evolution of selected design(s)
- Design findings/recommendations
We will also carry out assessments of the uncertainties associated with various phenomena to inform the integrated models.
Publications and Presentations
We’re just getting started. We’ll add papers and publications once we start producing them.
But if you’re looking for more information about our plans, here is a public version of our original proposal. Note that this version does not include scope changes in response to budget changes at award time.
