Modelling of Tritium Transport in a Pin-Type Solid Breeder Blanket

摘要

This study supplements a larger study of a solid breeder blanket design featuring lithium ceramic pins. This aspect of the study looks at tritium transport, release, and inventory within this blanket design. Li sub 2 O and gamma -LiAlO sub 2 are the two primary candidates for ceramic solid breeders. gamma -LiAlO sub 2 was chosen for this blanket design due to its higher structural stability. Analysis of tritium behavior in solid breeder blankets is of great importance due to its impact on several critical issues: the generation of an adequate amount of fusion fuel, the safety-related issue of keeping radioactive blanket inventories as low as possible, and the release, purge, and economical processing of the bred tritium without undue contamination of the coolant and other reactor structures.
