Shielding materials in the compact spherical tokamak [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019
Neutron shielding materials are a critical area of development for nuclear fusion technology. In the compact spherical tokamak, shielding efficiency improvements are particularly needed because of severe space constraints. The most spatially restricted component is the central column shield.

“PROCESS”: Systems studies of spherical tokamaks [PDF]

Fusion Engineering and Design, 2020
With a reduced aspect ratio, spherical tokamaks have a number of attractive features for a fusion power plant. This can be studied using systems codes, which allow for the rapid conceptual study of power plants covering everything, from the plasma through to electricity generation. In this paper, we describe models in the systems code PROCESS that have

A Neutron Source Based on Spherical Tokamak

Energies
The paper presents a conceptual study of a neutron source based on a spherical tokamak (ST). The plasma scenario chosen for the ST is non-thermal fusion (hot ion mode), which is extensively used on machines like JET and TFTR deuterium–tritium (DT ...

Design of power supply system for the NanChang Spherical Tokamak

AIP Advances, 2022
The NanChang Spherical Tokamak (NCST), a new compact (plasma major radius R = 0.40 m, minor radius a = 0.24 m, and aspect ratio A = 1.67) spherical tokamak, is suitable for teaching and scientific research activities at the university. The principal goal

Kinetic-ballooning-limited pedestals in spherical tokamak plasmas [PDF]

Nuclear Fusion
A theoretical model is presented that for the first time matches experimental measurements of the pedestal width-height Diallo scaling in the low-aspect-ratio high- β tokamak NSTX.

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials. [PDF]

Small Methods
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

Methodology of Plasma Shape Reachability Area Estimation in D-Shaped Tokamaks

Mathematics, 2022
This paper suggests and develops a new methodology of estimation for a multivariable reachability region of a plasma separatrix shape on the divertor phase of a plasma discharge in D-shaped tokamaks.
