North American construction is back—smaller and faster—at OPG’s Darlington
“The nuclear renaissance is real here,” said Ontario Power Generation’s Subo Sinnathamby on May 8, one year to the day after OPG secured a final investment decision to build the first of four planned BWRX-300 reactors at its Darlington nuclear power plant, and shortly after the new reactor’s foundation was lifted into place. “We got our license to construct in April and our [final investment decision] in May, and we’ve been off to the races since.”

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.
