2. 2 Some General Guidelines for the US TBM Costing Cost for the Reference Case Cost is for the period between now and the shipment of the TBM deliverables (Test articles and ancillary equipment) in 2015 for DAY ONE ITER operation. The period is 10 years from 2006 to 2015 The cost is the total cost for the TBM project (based on the Reference designs/deliverables) including R&D, design, engineering, fabrication, qualification, etc., as well as the cost of interface with ITER and other parties. The deliverables are based on the Reference Designs described in the Design Summary Documents. The DCLL Reference Case has a PbLi exit temperature of 470ºC and a test module that occupies half a port. For the HCCB: submodule that has a size of 1/3 of one-half port and uses the EU (or Japan) first wall/box (first wall/box is not part of the US deliverables) The R&D Cost includes all costs related to the reference design that occur within the next 10 year period whether they are related to the first (Day ONE) Test Articles or subsequent test articles. But the Cost of the deliverables includes only the cost of the First Test Article and associated equipment. The US effort should take advantage of the R&D efforts in other parties. R&D performed by other parties and available to the US should, in general, not be duplicated by the US and should be costed separately. Cost estimates should state clearly what R&D done by the other parties is essential to the US TBM project. (agreed to August 31, 2005)
