Plasma-Wall Interaction in DEMO 2022: Status and Plans
Explore the theory, simulation, verification, and validation tasks related to plasma-wall interaction in DEMO 2022. The project involves analyzing plasma background, wall geometry, material choices, heat loads, and ion fluxes. Tasks for 2022 include implementing modules, performing simulations, and ensuring IMAS compatibility. The team aims to enhance parallelization, optimization, and IMASization for effective project execution.

TASKS 2022 1. Implement the gyromotion module in SDTrimSP-3D 2. Implement neutron damage and damage stabilization models in retention codes 3. Perform TESSIM and FESTIM simulations of fuel accumulation in DEMO PFC and permeation to coolant (so far without neutron effects) 4. Detailed analysis of input/output of all involved codes to summarize how it can be reduced to IMAS compatible interfaces; identify the work program for IMAS compatibility implementation with ACH DELIVERABLES 2022 1. Gyromotion module in SDTrimSP-3D 2. Neutron damage (not yet validated) model with damage stabilization in retention codes 3. Predictions of fuel inventory and permeation under DEMO condition (so far without n- damage) 4. Detailed IMAS compatibility requirements and respective work plan D.
