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.

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.

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 ...

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.

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.

Tritium inventory and permeation in the ITER breeding blanket

Fusion Engineering and Design, 2000
Abstract A model has allowed us to perform the analysis of the tritium inventory and permeation in the international thermonuclear experimental reactor (ITER) breeding blanket under the hypothesis of steady state conditions. Li 2 ZrO 3 (reference) and Li 2 TiO 3 (alternative) have been studied as breeding materials.
