Description

Initial points for the panel:

1. The Tritium Breeding Challenge: Beyond the TBR > 1.0:
   The most urgent task for fusion energy realization is demonstrating Tritium Self-Sufficiency.

2. High-Fidelity "Digital Twins" for Radiation Damage:
   To accelerate the practical use of fusion, we must predict the lifetime of the First Wall and Vacuum Vessel without waiting decades for experimental data.

3. Neutronics of Advanced and Non-DT Fuels:
   While DT (Deuterium-Tritium) is the primary focus, the panel could explore how neutronics enables "cleaner" or more efficient cycles. Assess the neutronics of Cat-DD or Proton-Boron cycles.

4. Safety, Licensing, and Radwaste Classification:
   For a fusion plant to be "practical," it must be licensable by civilian nuclear authorities. Accurate assessment of Shutdown Dose Rate (SDDR) and Activation Analysis.
