Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

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.
