A review of workforce trends in the nuclear community
The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

This technical note describes the use of graphene as a way to protect plasma facing components from erosion, sputtering and diminished plasma performance and to extend component lifetimes in experimental plasma devices. In this work, 30 keV ionized helium is used as a projectile on graphene covered tungsten over a range of fluences. Graphene’s vacancy yield (ID) and natural resonance (IG) are found at ~1350 cm−1 and ~1550 cm−1, respectively. Damage of each sample is quantified using the ID/IG ratio via Raman spectroscopy (RS) at the aforementioned wave numbers. The surface morphology is studied using Scanning Electron Microscopy (SEM) and the mass losses are recorded using a high-precision scale. The results from this study are of considerable importance since they indicate that a graphene coating could be an effective candidate for reducing erosion in different PFC materials.
