Researchers at Russia’s NRNU MEPhI (National Research University - Moscow Power Engineering Institute) are investigating the accumulation of helium and deuterium in promising "smart" W-Cr-Y alloys for use in thermonuclear reactors. The results of the study were published in the Journal of Nuclear Materials. The interaction of plasma with the inner wall of a fusion reactor are a major obstacle to achieving fusion energy, explained Zori Arutyunyan, Candidate of Physical & Mathematical Sciences, and Junior Researcher at MEPhI’s Department of Plasma Physics.

The Nuclear Regulatory Commission said submissions must be filed by 10 March 2020 by anyone who wishes to participate in the hearing process for the application.
Shine has proposed to construct and operate a facility in Janesville, Wisconsin for the production of the radioisotope molybdenum-99 (Mo-99) through the irradiation and processing of a uranyl sulfate solution. The company said this patented process replaces a nuclear reactor with a low-energy, accelerator-based neutron source.
This source functions by colliding deuterium ions with tritium gas to cause fusion. The fusion reaction results in high energy neutrons and helium-4. In other words, the accelerator takes a radioactive by-product created by nuclear power plants (tritium) and turns it into the same clean, harmless gas used to make balloons float.
