In this study, YH x (where x represents the H/Y ratio) monoliths were fabricated using Spark
Plasma Sintering (SPS), employing yttrium hydride powder as the raw material. The effects …

YH 2 bulk is regarded as the most potential metal hydride to be used as neutron moderator
of microreactors serving as likely space nuclear power. In this work, YH 2-x monoliths are …

Fusion and fission reactions are profoundly dependent on hydrogen for sustained reactions.
Fusion is fueled by the isotopes of hydrogen, and predominantly hydrogen-based …

The emergence of microreactor technology has helped to drive supporting nuclear materials
qualification and acceptance processes. One essential component in these small reactors is …

Spark plasma sintering (SPS) shows great potential in the fabrication of bulk YH 2-x. For the
first time, the high-pressure SPS (HPSPS) of YH 2-x is explored and compared with the …

Abstract The Transformational Challenge Reactor is a 3-MW (thermal) helium-cooled
experimental nuclear reactor designed using an additive manufacturing–informed agile …
