Engineering Group Discussion of Tasks(next 6-12 months)

M. S. Tillack

ARIES Project Meeting25-26 October 2010

Action Items System code contributions (Lane and Chuck)

(end of Nov inputs, end of Dec implement)1. Output formatting (Lane, Laila, Les, Chuck, …)2. System code models of volumes, inclusion of He systems

(Lane, Laila, Les)3. New models for pumping power – He (Mark, Minami, Xueren)

and PbLi (Mark, Neil, Siegfried)4. Power cycle model (First quantify the impact of uncertainties)

(Mark, Xueren, Lane)5. Poloidal distribution (including divertor) of heat flux

CAD skeleton (Xueren) Wall load and core radiation formulas (Laila) Mantle and divertor radiation (Mark, Tom?, Chuck?)

1. Define the approach for modeling heat fluxes in the code2. Provide the models

6. Decommissioning and waste handling costs (Laila)

Action Items, continued

PFC concept improvement and analysis Addition of creep (Wang) Fracture mechanics (Jake) Pin fin plate concept thermomechanics (GT/UCSD)

CAD and analysis of 4 strawman design points (all) Preliminary results (3-6 month) Final power core design and analysis (12 months)

(which includes divertors and first walls)

Action Items, continued Materials issues (Arnie)

FS and ODS FS Creep data for FS and ODS FS Creep and stress/strain for F82H and ODS-F82H

(is it any different than Eurofer and ODS-Eurofer) W and W alloys (W, WL10, W-TiC, VM-W)

Recrystallization temperature (1200?) Low operating temperature limits

SiC/SiC composites Has anything changed in the past 10 years?

* Thermal conductivity under irradiation* High temperature compatibility with flowing PbLi

Ta alloys UE of Ta and Ta-2.5W, Guidance on irradiation

degradation of UE

Action Items, continued

Safety issues (Lee)

Guidelines for tritium release, concentrations, inventory.

Compare with ITER. Does ARIES meet these guidelines? Define the confinement boundary. Impact on cost of components.

(The vacuum vessel is a safety-related component. Which others should be considered safety-related components?)
