TerraPower, the Bill Gates-backed nuclear innovation firm, has launched a new small modular reactor system paired with a molten salt storage unit. The new concept, dubbed Natrium, is being developed in partnership with GE Hitachi Nuclear Energy. According to the pair, it could be used to boost a 345-megawatt small modular reactor (SMR) to around 500 megawatts for a period of up to five hours. TerraPower, founded by Gates in 2008, is developing two separate SMR technologies. The sodium fast reactor used in the Natrium concept produces large volumes of heat over and above what is required to drive its steam turbines. The company has previously flagged this as a potential source of process heat or for energy storage. The Natrium system gives it a commercial concept for the latter.
