WebOct 1, 2015 · To quantify the impact, the tritium breeding radio (TBR) is calculated for various materials employed by the first wall. As shown in Fig. 2, when the first wall is thickened from 2 mm to 2 cm, the TBR decreases ∼13.2% for pure Eurofer and ∼16.3% for … WebJan 9, 2024 · Tritium is not a primary fuel and does not exist in significant quantities naturally since it decays with a half life of 12.3 years. It therefore has to be "bred" from a separate nuclear reaction.

The tritium breeding blanket (also known as a fusion blanket, lithium blanket or simply blanket), is a key part of many proposed fusion reactor designs. It serves several purposes; one is to act as a cooling mechanism, absorbing the energy from the neutrons produced within the plasma by the nuclear fusion reaction between deuterium and tritium (D-T), another is to "breed" further tritium fuel, that would otherwise be difficult to obtain in sufficient quantities, through the reaction of neutro… WebOct 1, 2024 · Tritium breeding ratio (TBR) 1.2: Duty factor (DF) 1/0.5: In was considered that the 500 MW operation stage was a good balance point for the lifetime operation of CFETR. As for the overall burning efficiency, it was conservatively assumed that 1% could be achieved for the 500 MW operation stage, 2% and 3% could be achieved for the 1000 MW …

The release and diffusion of tritium and helium produced by the fission of lithium can take place within ceramics referred to as breeder ceramics. The production of tritium from lithium-6 in such breeder ceramics is possible with neutrons of any energy, though the cross section is higher when the incident neutrons have lower energy, reaching more than 900 barns for thermal neutrons.
