The manufacturing technologies of the European breeding blankets

Journal of Nuclear Materials, 2004
In the European Union, the basic manufacturing technologies have been selected for the two reference DEMO breeding blanket concepts: the helium cooled pebble bed and the helium cooled lithium lead. These technologies have been tested in the past years on small-scale samples and mock-ups, are presently under further development, and are now being ...

ITER reference breeding blanket design

Fusion Engineering and Design, 1999
The ITER reference breeding blanket design is water-cooled and is characterised by the use of the neutronic multiplier and breeder materials in the form of pebbles. Besides the achievement, with margin, of the tritium breeding ratio (TBR) minimum requirement, it exhibits an internal layout allowing it to withstand properly electromagnetic loads during ...

A breeding blanket in ITER-FEAT

Fusion Engineering and Design, 2003
Abstract At the beginning of life ITER-FEAT will be equipped with a shielding blanket; nevertheless since many advantages can be envisaged in having a breeding blanket in the machine, such a concept has been investigated as well. It is a water-cooled blanket in which both ceramic breeder and beryllium multiplier are present in the form of single ...

Multilayered Blanket Concept for Tritium Breeding Assemblies Blanket Engineering

Nuclear Technology - Fusion, 1983
The multilayered concept of the fusion blanket is introduced, and it is shown that with this concept the lithium inventory can be reduced by an order of magnitude compared to that in the block conc...

Breeding blanket concepts for fusion and materials requirements

Journal of Nuclear Materials, 2002
This paper summarizes the design and performances of recent breeding blanket concepts and identifies the key material issues associated with them. An assessment of different classes of concepts is carried out by balancing out the potential performance of the concepts with the risk associated with the required material development.

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.

Cylindrical breeding blankets for fusion reactors

Fusion Engineering and Design, 2018
Abstract Blankets with a cylindrical structure have been developed for a water-cooled ceramic breeder concept considering a pipe break inside the blanket container. Most existing studies have examined a box structure for the blanket container. Structural change from a box to a cylinder can decrease in first wall thickness while maintaining the ...

Detection of Breeding Blankets Using Antineutrinos

Science & Global Security, 2016
The Plutonium Management and Disposition Agreement between the United States and Russia makes arrangements for the disposal of 34 metric tons of excess weapon-grade plutonium. Under this agreement Russia plans to dispose of its excess stocks by processing the plutonium into fuel for fast breeder reactors.

Thermal mechanical analysis of a solid breeding blanket

Fusion Engineering and Design, 2003
Abstract This paper deals with a theoretical model of thermal mechanical behaviour of pebble beds, used as neutron multiplier or tritium breeder in the breeding blanket of a fusion nuclear reactor. The model tries to sum up the advantages of the two approaches (‘discrete’ method and macroscopic method), presently used for analysing the pebble bed ...

Status of the European breeding blanket technology

Fusion Engineering and Design, 1997
Abstract This paper presents an overview of the activities within European laboratories on the development of breeding blankets for a DEMO reactor which are presently focused on the two selected blanket lines, the Water-Cooled Lithium–Lead (WCLL) blanket and the Helium-Cooled Pebble-Bed (HCPB) blanket.
