What? Seaborg “is developing a nuclear reactor technology fundamentally different from what exists today”.

What, exactly? Many nuclear reactor designs exist, but the majority makes use of pressurized water as both the moderator and the coolant. Molten salt reactors (MSR) are a generation IV alternative being researched today that, according to Seaborg, has the potential to be affordable, “[is a] sustainable and safe technology [and could] revolutionise energy markets.”
