Fatigue life of the plasma-facing components in PULSAR

Fusion Engineering and Design, 1995
Abstract The PULSAR project is a multi-institutional effort to determine the advantages that can be gained by building a tokamak with an entirely inductive current drive. This machine, which would operate in a pulsed mode, would feature reduced capital and operating costs compared with steady-state devices requiring complex current drive systems ...

Armour Materials for the ITER Plasma Facing Components

Physica Scripta, 1999
The selection of the armour materials for the Plasma Facing Components (PFCs) of the International Thermonuclear Experimental Reactor (ITER) is a trade-off between multiple requirements derived from the unique features of a burning fusion plasma environment.

Beryllium plasma-facing components: JET experience

Fusion Engineering and Design, 1997
Abstract JET has accumulated practical experience of plasma operation in both limiter and divertor configurations using massive beryllium plasma-facing components. These latter have shown evidence, even after a very short operational phase, for localised melting of the beryllium surface.

ITER plasma facing components, design and development

Fusion Engineering and Design, 1991
Abstract The paper summarizes the collaborative effort of the ITER Conceptual Design Activity (CDA) on Plasma Facing Components (PFC) which focused on the following main tasks: (a) the definition of basic design concepts for the First Wall (FW) and Divertor Plates (DP), (b) the analysis of the performance and likely lifetime of these PFC designs ...

Advances in tungsten-armored plasma facing components

Proceedings of the 19th IEEE/IPSS Symposium on Fusion Engineering. 19th SOFE (Cat. No.02CH37231), 2003
High-Z armor is appropriate for use on plasma facing components (pfcs) subjected to very high heat loads and low plasma edge temperatures. During the past several years much progress was made on the development of tungsten rod armor bonded to water-cooled heatsinks.

Overview of plasma-facing materials and components for EAST

Physica Scripta, 2007
By the end of September 2006, the engineering commissioning of the Experimental Advanced Superconducting Tokamak (EAST) was completed and the first H2 plasma was achieved with stainless steel as the plasma-facing material (PFM). In the following phases, with gradual increase in the heating power, the EAST divertor targets have to handle expected heat ...

Development of beryllium bonds for plasma-facing components

Journal of Nuclear Materials, 1992
This study concerns the techniques of bonding beryllium to both structural material (AISI 316 SS) and heat sink material (copper and DS-copper) plates, and the characterization of the bonding material obtained. Conventional bonding techniques for joining Be to SS and copper using brazing alloys were first investigated, The best, result was obtained ...

Development of doped graphites for plasma-facing components

Fusion Engineering and Design, 2001
Doping of carbon leads to a reduction of chemical erosion. This reduction is more effective if dopants are in the form of sub-μm precipitates with a very homogeneous distribution. However, dopants should not degrade but rather improve the thermal conductivity of graphite.

Effects of runaway electrons on plasma facing components

Fusion Engineering and Design, 1994
Abstract The electron gamma shower code EGS4 was applied to the simulation of energy deposition due to runaway electrons in the plasma facing components of tokamaks. By taking into account the magnetic field, we calculated the energy deposition in the layers of carbon and molybdenum irradiated by electrons with energies from 10 to 300 MeV and an ...
