Program status 4. quarter -- FY 1993: ITER and technology

Work continued on the development of the high-pressure helium-cooled design for the PULSAR reactor study. It was found that the high pressure helium-cooled solid breeder design may be able to breed adequate tritium without the use of Be as the neutron multiplier. Thermal-hydraulic results also indicate that the ARIES-IV shield can be used as the thermal storage component, while keeping outlet coolant temperature constant during the dwell time of about 2 minutes. During this period, two TE{sub 22,6} mode generators were fabricated and a report on the testing of the RF vacuum feed-throughs were written. Also, the DiMES sample chamber was operated in a piggyback mode and different samples were exposed to the DIII-D plasma during dedicated physics experiments
