Tritium transport model at the minimal functional unit level for HCLL and WCLL breeding blankets of DEMO

Fusion Engineering and Design, 2018
The Helium-Cooled Lithium-Lead (HCLL) and Water-Cooled Lithium-Lead (WCLL) Breeding Blankets are two of the four European blanket designs proposed for the DEMO reactor. A tritium transport model inside the blanket is fundamental to assess its preliminary

European TBM programme: First elements of RoX and technical performance assessment for DEMO breeding blankets

Fusion Engineering and Design, 2020
The strategy for the development of the European DEMO Breeding Blanket (BB) and the TBM (Test Blanket Module) Programme have been recently realigned with the objective to mitigate the risks associated with the development of tritium breeding and power ...

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.

Tritium permeation issues for helium-cooled breeding blankets

2013 IEEE 25th Symposium on Fusion Engineering (SOFE), 2013
Tritium permeation through Breeding Blanket and Steam Generator heat transfer areas is a crucial aspect for the design of the next generation DEMO fusion power plants. Tritium is generated inside the breeder, dissolves in and permeates through materials, thus leading to a potential hazard for the environment.

High Performance Breeding Blankets for ICF Facilities

Nuclear Technology/Fusion, 1983
Discussed are the advantages of using fusion neutrons for breeding special nuclear materials and tritium. Monte Carlo calculations were used to identify both fissionable and nonfissionable materials that multiply neutrons and increase breeding ratios. Fissionable multipliers also greatly multiply the neutron energy.

The influence of MHD boundary layers on tritium permeation in PbLi flows for fusion breeding blankets

International Journal of Heat and Mass Transfer, 2021
In PbLi based breeding blanket concepts, tritium is produced inside the liquid metal and drag out of the reactor by the liquid metal flow. However, undesired permeation through the channels and pipes walls occurs spontaneously since tritium naturally ...

Breeding blanket development for NET

Fusion Engineering and Design, 1989
Abstract The design of blankets for NET is reviewed. Three categories of blankets are discussed: non breeding shield blankets for the physics phase, tritium producing driver blankets to operate the NET machine for extended periods of time in the technology test phase, and DEMO relevant blankets, which shall demonstrate their performance as test ...

Breeding blanket for DEMO

Fusion Engineering and Design, 1993
This paper presents the main design features, their rationale, and the main critical issues for the development, of the four DEMO-relevant blanket concepts presently being investigated within the framework of the European Test-Blanket Development Programme.

Numerical investigation of the tritium permeation phenomenon through cooling plates in breeding blankets

, 2020
Understanding and predicting tritium transport is considered a key issue for the design of safe and self-sufficient fusion power plants. Indeed, tritium generated in the breeder materials is susceptible to permeate to the blanket coolant circuits where ...
