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 ...

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.

Excitation of Whistler‐Mode Waves by an Electron Temperature Anisotropy in a Laboratory Plasma

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Naturally occurring whistler‐mode waves in near‐Earth space play a crucial role in accelerating electrons to relativistic energies and scattering them in pitch angle, driving their precipitation into Earth's atmosphere. Here, we report on the results of a controlled laboratory experiment focusing on the excitation of whistler waves via ...

Physics basis for the reference flat-top plasma scenario in the ST–E1 fusion power plant

Nuclear Fusion
As part of the U.S. Department of Energy’s Milestone-Based Fusion Energy Development Program, Tokamak Energy has completed the pre-concept design of the ST–E1 fusion power plant. ST–E1 is envisaged to operate in two phases: a pilot plant phase, targeting
