"Amazon recently announced it is putting US$500 million into X-energy, a Small Modular Reactor (SMR) start-up based in Maryland. This is hot on the heels of Google signing a Power Purchase Agreement for 500MW in new nuclear projects by Kairos Power. What does X-energy and Kairos have in common? Their SMRs both use TRi-structural ISOtropic (TRISO), an engineered fuel that is probably the most expensive fuel choice in nuclear, but also takes care of a lot of problems."
