A Systematic Framework for Risk Assessment of Fusion Blanket: Addressing Manufacturing Defects, Accident Scenarios, and Radioactive Release

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
The breeder blanket, as a critical component in fusion reactors, undertakes three essential functions: tritium breeding, neutron shielding, and thermal energy conversion. Serving as the primary plasma‐facing component, it operates under extreme conditions—including sustained high temperatures, intense neutron irradiation fluxes, significant ...

Heating by an Electron Bernstein Wave in a Spherical Tokamak Plasma via Mode Conversion [PDF]

, 2006
The first successful high power heating of a high dielectric constant spherical tokamak plasma by an electron Bernstein wave (EBW) is reported. An EBW was excited by mode conversion (MC) of an X mode cyclotron wave injected from the low magnetic field ...

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion

International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1541-1557, December 2025.
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

The Solar Wind Interaction With an Orbiting Venus

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Studies of the large‐scale interaction of the solar wind with planets have often been considered along the line of the sun to the planet, neglecting the planet's orbital motion. This paper describes a new refinement in the long history of Venus simulations, the addition of the planet's orbital motion.

Pressure Drop in Capsule Transporting Bends Carrying Spherical Capsules [PDF]

, 2012
One of the most important parameters in designing a capsule transporting pipeline is the pressure drop in the pipes carrying capsules and associated pipe fittings such as bends etc.

Performance prediction applying different reduced turbulence models to the SMART tokamak

Nuclear Fusion
The SMall Aspect Ratio Tokamak (SMART) is currently being commissioned at the University of Seville and will be able to compare the performance of positive and negative triangularity plasmas at low aspect ratio. Predictive simulations have been performed

A h‐Adaptivity Strategy for Hybridizable Discontinuous Galerkin (HDG) Simulations of Fluid Transport Models in Tokamak Plasma

International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.
ABSTRACT The highly anisotropic, multi‐scale nature of fusion plasma simulations in tokamaks, combined with the complexity in the geometries of plasma‐facing components and magnetic equilibrium, challenges numerical schemes. They therefore require the development of advanced numerical techniques to enhance computational efficiency and enable codes to ...

Overview of fast particle experiments in the first MAST Upgrade experimental campaigns

Nuclear Fusion
MAST-U is equipped with on-axis and off-axis neutral beam injectors (NBI), and these external sources of super-Alfvénic deuterium fast-ions provide opportunities for studying a wide range of phenomena relevant to the physics of alpha-particles in burning
