SC Nuclear Summit focuses on V.C. Summer
The second annual South Carolina Nuclear Summit held last week featured utility executives and legislators from the state, as well as leaders from Brookfield Asset Management, which is being considered to restart construction on the two abandoned reactors at the V.C. Summer nuclear power plant in Fairfield County. The summit, at the University of South Carolina’s Colonial Life Arena, attracted more than 350 attendees. The event was hosted by the university’s Molinaroli College of Engineering and Computing.

This research explores the performance of graphene as a coating for plasma-facing components (PFCs) in a nuclear fusion environment. Our recent studies have shown that graphene can act as a resistant layer against plasma exposure and ion bombardment. PFCs tend to develop surface morphologies that lead to mass loss of the wall material, potentially diminishing their lifetime and degrading plasma performance. We present a characterization of graphene-coated samples of W irradiated in the C-2W divertor. Energy analyzers were used to determine average ion fluxes to the samples on the order of 1018 D+/cm2. Two samples were exposed over 1210 plasma discharges. Raman spectroscopy showed that slow ions (30 < E < 100 eV) interact strongly with the graphene, introducing vacancies into the membrane (ID/IG ~ 0.7), making it possible to assess the limiting factors on such a coating’s lifetime. We also found that graphene slows down impurity deposition on the material surfaces due to graphene’s stable configuration and low surface energy. This first attempt at testing the coating in a large-scale fusion experiment aims to expand the possible wall candidates for PFCs.
