Abstract
Within the past year, major reactor design studies have been performed using Li/sub 2/O as a breeder material. These are the INTOR and STARFIRE/DEMO projects. We in our studies on fusion/synfuels are embarking on another, but our blanket will operate at significantly higher temperatures than these two. Some of the problems inherent in using this material are aggravated and some are diminished by operating at higher temperatures. For the conditions of the above two design studies many of the problems were mentioned in the respective references. This report reviews the available data, the educated guesses about unavailable data, and the design options that have been and are being chosen. The review of this information is a needed part for our proposed use of Li/sub 2/O as a breeder in a fusion/synfuel reactor blanket. Further details will be available in various appropriate sections of our FY82 project report.
