Effects of lithium burn-up on TBR in DEMO reactor SlimCS

Thermal conductivity of non-stoichiometric Li2TiO3

“…During operation, lithium will undergo transmutation to generate tritium for the plasma and so the material will be increasingly Li deficient as it ages; Li burn-up may reach several 10s of % during a typical blanket lifetime [15]. Therefore, it is important to be able predict the thermal conductivity of the titanate across a wide stoichiometric range.…”

Neutronics design and radiological aspects of HiPER facilities

“…This can represent a serious storage (T excess) or availability (T shortage) problem. This variation may very easily arise from design tools limitations, or by lithium burn-up [118]. Thus, the fine tuning of the TBR (<1%) is a must for a blanket design.…”
