TRITIUM BREEDING CALCULATION IN A STELLARATOR BLANKET

Problems of Atomic Science and Technology, 2019
In current blanket projects, tritium breeding ratio (TBR), the ratio of tritium production rate to the neutron production rate, is low (1.1…1.2). The MCNPX Monte-Carlo code has been used to model the neutron kinetics and to look for a principal possibility of increase TBR within a stellarator blanket limited space.

Tritium Breeding in Hybrid Reactors

Fusion Technology, 1986
The difficulty of achieving tritium self-sufficiency in a deuterium-tritium (D-T) hybrid has been reported in relation to different hybrid designs and concepts using lithium as the breeding material. Lithium-6 enrichment has been suggested to overcome this problem, provided the contribution of /sup 7/Li to tritium production is usually negligible, as ...

Behaviour of tritium in breeding materials

Fusion Engineering and Design, 2005
Abstract The tritium release from ceramic materials of the HCPB under real DEMO operating conditions will depend not only on temperature and neutron flux but also on an intense magnetic field (MF) of 7–9 T. The delay in the tritium release induced by the MF is proportional to the grain size of the ceramics, the squared MF intensity and the abundance ...

Properties and performance of tritium breeding ceramics

Journal of Nuclear Materials, 1992
Lithium-containing ceramics are being strongly considered as tritium breeding materials for fusion reactor blankets owing to their good thermal stability, favorable chemical behavior and tritium breeding potential, and excellent tritium release characteristics. The research effort has focused on four compounds: Li 2 O, γ-LiAIO 2 , Li 4 SiO 4 , and Li 2

Deuterium-tritium fusion reactors without external tritium breeding

Physics Letters A, 1998
Abstract An inherent property of deuterium fusion burn-up equations is presented, due to which deuterium-tritium reactions can be exploited without needing tritium breeding in external blankets. A small amount of tritium is added to the deuterium plasma in order to trigger ignition at less than 10 keV, and the same amount of tritium is found in the ...

Tritium fuel cycle modeling and tritium breeding analysis for CFETR

Fusion Engineering and Design, 2016
Abstract Attaining tritium self-sufficiency is a critical goal for fusion reactor operated on the D–T fuel cycle. The tritium fuel cycle models were developed to describe the characteristic parameters of the various elements of the tritium cycle as a tool for evaluating the tritium breeding requirements.

Compatibility problems in tritium breeding blankets

Journal of Nuclear Materials, 1991
Abstract The compatibility between tritium breeding materials (liquid or solid), neutron multiplier and structural steels is a concern for the choice of a tritium breeding blanket for NET. For solid tritium breeding blanket, it seems that the more severe compatibility problem is due to the interaction of beryllium with steel.

An Assessment of Tritium Breeding Requirements Based on the Tritium Fuel Cycle

Fusion Technology, 1986
An assessment of tritium breeding requirements for fusion power reactors is presented. The analysis is based on an evaluation of time-dependent tritium inventories in the reactor system. The method presented can be applied to any fusion systems operating in a steady-state mode as well as in a pulsed mode.

Phase composition control of biphasic tritium breeding ceramics and correlation behavior of lithium and tritium

Journal of Nuclear Materials, 2021
Abstract Biphasic tritium breeding ceramics were prepared by the microwave-induced solution combustion (MSCS) method in a single step. The phase ratio of lithium titanate and lithium silicate can be effectively controlled by changing the Si/Ti atom ratios in the aqueous precursor.
