Study of the impact of a pulsed plasma flow on thermonuclear reactor materials

2024 IEEE International Conference on Plasma Science (ICOPS)
There are several challenges to implementing thermonuclear fusion. Some of these problems are related to the interaction of the plasma with the first wall and divertor materials [1, 2].

Protective nitrided layers for the structural materials of thermonuclear reactors

Soviet Atomic Energy, 1987
Application of protective coatings based on light elements having strong interatomic bonds is one of the most practical and promising methods of decreasing the rate of erosion (wear) of the first wall of thermonuclear reactors due to ion sputtering and blistering.

Questions of the corrosion resistance of vanadium alloys as a possible thermonuclear reactor constructional material

Soviet Materials Science, 1988
For the presumed operating conditions of a type INTOR thermonuclear reactor [i] a basic advantage of vanadium is the relatively rapid drop in the induced activity [2] (by about a million times after a 10-yr hold). This property is preserved in alloying of vanadium with titanium, chromium, aluminum, silicon, and carbon but becomes significantly poorer ...

Investigation of ferromagnetic phase precipitation on the surface of some constructional materials for thermonuclear reactors

Journal of Nuclear Materials, 1981
Abstract Austenitic stainless steels are considered as a prospective material for the first wall of the thermonuclear reactors. Radiation and temperature influence erosion of material, and contamination of the plasma. This paper describes the results of investigations on the process of ferromagnetic layer formation on the surface of Cr-Mn and Cr-Ni ...

Deuterium Plasma Focus as a Tool for Testing Materials of Plasma Facing Walls in Thermonuclear Fusion Reactors

Journal of Fusion Energy, 2016
This paper presents the first verification of the fast ion beam (FIB) and fast plasma stream (FPS) properties computed using the Lee code. Recent estimates of FIB and FPS properties in PF-400J from interferometric images are compared to our computed results. Reasonable agreement is found in the comparison of several quantities.

Mechanical properties of oxygen-injected vanadium alloy for application as structural component material for international thermonuclear experimental reactor

Journal of Nuclear Materials, 1996
Abstract The effect of oxygen injection on the mechanical properties of vanadium alloys was investigated. Tensile testing of oxygen-containing and reference specimens were performed at temperatures up to 1000°C. Results show that, in general, oxygen decreases the ductility and increases the ultimate tensile stress.

Influence of hydrogen upon the solubility, in lithium, of the structural materials of the blanket of a thermonuclear reactor

Soviet Atomic Energy, 1990
Models of an association solution, i.e., a regular solution with two sublattices, a quasi-chemical sublattice and a coordination-cluster sublattice, are used to describe the interaction of the components in diluted liquid-metal solutions. The influence of hydrogen upon the solubility of the metals in the liquid lithium was studied in our work, making ...

The absorption of deuterium by carbon-based facing materials on components in contact with the plasma in a thermonuclear reactor

Atomic Energy, 1997
The conditions have been proposed for performing modeling experiments making it possible to predict the accumulation of hydrogen isotopes in carbon materials which are in contact with a tokamak plasma acting as a source of particles having a flux density of between 3×1016 and 3×1019 cm−2·sec−1.
