Finalize venue, lodging, dining plan, agenda (April ‘10)

6. First Wall Design and Engineering
Initial analysis of innovative FW concept was performed using ASME 3Sm rules. Results show that temperature limits are met, but stress limits are exceeded at 2 MW/m2 heat flux.
Next step is to analyze true stress/strain behavior, including plasticity and creep, throughout fabrication and operation (normal and off-normal events).
Need design rules (failure criteria) for this case.
From Physics Group: Need time-dependent and power and particle flux with spatial definition.
Per management direction: maintain record of latest best estimate of maximum q” capability.

7. Divertor Design and Engineering
Initial analysis of combination plate/finger concept was done including front and back elements
Next step is to analyze true stress/strain behavior, including plasticity and creep, throughout fabrication and operation (normal and off-normal)
Other tasks:
Detailed analysis of steel/tungsten joint
T-tube concept improvement and analysis
Similar to FW
Need design rules (failure criteria) for full analysis method
From Physics Group: Need time-dependent and power and particle flux with spatial definition
Per management direction: maintain record of latest best estimate of maximum q” capability for each concept
What should we do about particle loads and erosion?

8. System Studies
Define the four corners (PPPL) based on parametric studies
Reevaluate SC coil capabilities, algorithms in code
Restart systems code runs at UCSD (done)
Need to coordinate code use at PPPL and UCSD (tbd)
Plot & visualize data, investigate additional visualization techniques (need guidance)
Prepare to add/replace/manipulate code modules, as needed
Finish implementing new costing algorithms???

9. Nuclear Analysis Stabilizing shell location Streaming issue
Impact of new FW on neutronics (pending definition of locations
