Model and Mockup of DEMO Ceramic Breeding Zone for Testing in the IVV-2M Reactor

RF TBMs for ITER tests

“…The main technical requirements for these reactors are the following: (1) total electric power around 1.5 GW; (2) the tritium breeding ratio (TBR) ≥1.05-1.1; (3) the structural materials should withstand the first wall fluence up to [15][16][17][18][19][20] MWa/m 2 with the possible replacement of in-vessel components after 5-10 MWa/m 2 .…”

“…The functional reactor facility (RITM-F) for tritium breeding models tests has been fabricated and put into operation [16,17]. The in-pile testing of breeding zone model for the CHC TBM in the conditions of permanent tritium extraction have been performed [18].…”

Research and development of lithium ceramics and models of tritium breeding zones for blankets in Russian reactor projects

“…The pebble model of the Test Module was discussed in [4]. At the concept development stage of DEMO, lithium orthosilicate was chosen as the tritium breeding material and beryllium pebbles as the neutron multiplying element.…”

“…12,No. 4, However, ceramics have some drawbacks -the main one being a restricted service life of the TBZ, because lithium ceramics can only operate under neutron irradiation for a limited time.…”

“…The experimental value of the HTO/(HT þ HTO) ratio may serve as an initial requirement for the design of the tritium system of the ITER Test Module. A period of reactor operation, corresponding to the time needed for the reactor to reach full power, is described in [4].…”
