US DCLL TBM and PbLi Loop –
Port Cell View
US DCLL TBM –
2 mm gap
A technical plan for US ITER TBM has already been developed.
A good cost estimate was generated through the combined efforts of the technical experts from:
Plus ORNL costing & management professionals
An external review by US DOE technical and project experts found the cost and plan “complete and credible”
The costs depend strongly on the level of international collaboration and timing
IF US is “going it alone”, R&D costs are likely to be larger than that given in this estimate.
Some tritium extraction R&D and fabrication delayed till 2nd module
A full size, vertical half-port, DCLL test blanket module
Primary and secondary DCLL helium coolant flow loops
A DCLL PbLi coolant flow loop and HXs
Component specifications sufficient to fabricate the tritium processing systems
Preliminary T Processing Systems Flow Chart
HCCB thermofluid and DCLL MHD flow
A verified predictive capability sufficient to design, qualify, operate, and interpret data for the H-H phase TBMs, and to design later D-D and D-T phase TBMs and ancillary systems and diagnostic systems;
TBM R&D tasks have been reviewed based on the minimum necessary to:
At a minimum, this same R&D will be needed before testing the DCLL in any US FNS device
(still being quantitatively defined)
TBMs must not interfere with
ITER operation or safety
Ancillary systems must be licensed as safety grade
TBMs must be DEMO
