Comment on "Deuterium--tritium fusion reactors without external fusion breeding" by Eliezer et al

, 2002
Inclusion of inverse Compton effects in the calculation of deuterium-deuterium burn under the extreme conditions considered by Eliezer et al. [Phys. Lett. A 243 (1998) 298] are shown to decrease the maximum burn temperature from about 300 keV to only 100-

Testing 3D Printed Carbon Fiber Durability for Next‐Gen Fusion Reactors via Proton Irradiation

Polymer Composites, Volume 47, Issue 1, Page 924-941, 10 January 2026.
Schematic of proton irradiation effects on carbon fiber samples evaluated via nanoindentation and Raman spectroscopy. ABSTRACT Carbon fiber‐reinforced composites are promising candidates for plasma‐facing components (PFCs) in next‐generation fusion reactors due to their high strength‐to‐weight ratio, thermal stability, and radiation resistance. However,

Observation of alpha-particles in recent D–T experiments on JET

Nuclear Fusion
The fusion reaction between deuterium and tritium, D ( T,n ) ^4 He is the main source of energy in future thermonuclear reactors. Alpha-particles ( ^4 He -ions) born with an average energy of 3.5 MeV transferring energy to the thermal plasma during their

Heat Transfer of Viscous MHD Nanofluid Flow in the Presence of Solar Radiation With Entropy

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.
To satisfy the power needs of human beings without affecting the environment, scientists have been working on the efficient practices of renewable energy sources such as solar, water, and wind. As a source of energy resources, solar radiation is preferred because of its unlimited availability and low ecological impact.

Sources of tritium in natural-technogenic systems

Geo&Bio, 2020
The radioactive decay of tritium is caused by the β-decay of one of the two neutrons in the nucleus of the hydrogen isotope atom (triton) into a proton, electron, and electron antineutrino with the formation of a monatomic gas and a half-life of 12.33 ...

On the potential of physics-informed neural networks to solve inverse problems in tokamaks

Nuclear Fusion, 2023
Magnetic confinement nuclear fusion holds great promise as a source of clean and sustainable energy for the future. However, achieving net energy from fusion reactors requires a more profound understanding of the underlying physics and the development of

Massive stars as thermonuclear reactors and their explosions following core collapse

, 2009
Nuclear reactions transform atomic nuclei inside stars. This is the process of stellar nucleosynthesis. The basic concepts of determining nuclear reaction rates inside stars are reviewed. How stars manage to burn their fuel so slowly most of the time are
