WebThe breeding blanket will be the component in charge of extracting and amplifying the neutronic power in future Fusion Power Plants. In addition, it has to warrant the reactor tritium self-sufficiency through efficient breeding and recovery. An additional function is the protection of the vacuum vessel (VV) and magnets against radiation [1.]. WebBlankets containing lithium are referred to as breeding blankets. Through them, tritium can be bred indefinitely. Once the fusion reaction is established in a tokamak, deuterium and …

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… WebJun 1, 2015 · The breeding zones are named as CB-1 (ceramic breeder) and CB-2 ( Fig. 5 ).
