Chamber Technology Goals Used in APEX to Calibrate New Ideas and Measure Progress
 

Summary: Chamber Technology Goals Used in APEX to
Calibrate New Ideas and Measure Progress
1. High Power Density Capability
Average/Peak Neutron Wall Load ~ 7 / 10 MW/m2
Average/Peak Heat Flux ~ 1.4 / 2 MW/m2
2. High Power Conversion Efficiency (>40%)
3. High Availability (MTBF>43 MTTR)
4. Simpler Technological and Material Constraints
(80% of the Alpha Power Radiated to First Wall to
ease divertor loading)
* "APEX will explore concepts with lower power density capabilities if they provide significant
improvement in power conversion efficiency or other major features."
Technological limits for "conventional concepts" have been documented in several papers; see
for example APEX paper in Fusion Engineering & Design, vol. 54, pp 145-167 (1999)
APEX "Idea Formulation" Phase Identified
Two Classes of Promising Concepts:
Results of the "Idea Formulation" phase are fully documented on the website and
in many journal publications
An Interim Report (> 600 pages) fully documents all details:
"On the Exploration of Innovative Concepts for Fusion Chamber Technology",
