Program status 2. quarter -- FY 1990: Fusion technology development
During this period, the ARIES-I blanket design team has concentrated its efforts on preparation of the final report. For the ARIES-II blanket design, two concepts are being evaluated. They are the Li self-cooled and the helium-cooled lithium breeder designs. The scoping design of the second concept has been completed. Varian EIMAC has had two tube failures in trying to assemble the X2274 tetrodes for the tests in Japan. Despite the failures it is still possible for the tubes to be ready as scheduled. Also during this quarter, the joint US/PRC integral experiment on beryllium was completed in March and the analysis of results has begun. Finally, the final design of DIII-D Divertor Material Exposure System (DiMES) was completed. Preliminary analysis by ANL of DIII-D divertor erosion, using measured plasma conditions, predicts maximum net erosion of 50 {micro}m and maximum net deposition of 23 {micro}m. Measurement by SNL-L of the 12 tiles removed in December 1989 is still pending.
