Fusion blanket testing in MFTF-. cap alpha. + T

The Mirror Fusion Test Facility-..cap alpha.. + T (MFTF-..cap alpha.. + T) is an upgraded version of the current MFTF-B test facility at Lawrence Livermore National Laboratory, and is designed for near-term fusion-technology-integrated tests at a neutron flux of 2 MW/m/sup 2/. Currently, the fusion community is screening blanket and related issues to determine which ones can be addressed using MFTF-..cap alpha.. + T. In this work, the minimum testing needs to address these issues are identified for the liquid-metal-cooled blanket and the solid-breeder blanket. Based on the testing needs and on the MFTF-..cap alpha.. + T capability, a test plan is proposed for three options; each option covers a six to seven year testing phase. The options reflect the unresolved question of whether to place the research and development (R and D) emphasis on liquid-metal or solid-breeder blankets. In each case, most of the issues discussed can be addressed to a reasonable extent in MFTF-..cap alpha..+T
