Long Used but Hardly Known: Synthesis and Crystal Structure of Tritium Breeding Li₂Be₂O₃. [PDF]

Chemistry
The ternary oxide Li2Be2O3 was synthesized in a HT approach starting from Li2O and BeO using a radiofrequency furnace. Although, the compound has been known for almost 60 years, its crystal structure has only now been elucidated and a phase‐pure synthesis makes the determination of directly assignable properties possible.

Tritium Breeding Blanket [PDF]

Fusion Technology, 1991
The terms of reference for ITER provide for incorporation of a tritium breeding blanket with a breeding ratio as close to unity as practical. A breeding blanket is required to assure an adequate supply of tritium to meet the program objectives. Based on specified design criteria, a ceramic breeder concept with water coolant and an austenitic steel ...
