Transatomic Power is a small Cambridge-based company pursuing energy technology aimed at delivering clean, safe, and affordable nuclear power. It focuses on molten salt reactor concepts updated with modern materials as an alternative to conventional light-water reactors within the renewable energy landscape. Its objective is to provide carbon-free electricity at a price competitive with coal, with potential to replace retiring coal plants in the United States and offer an international option to displace new coal capacity. The design is described as inherently safe, relying on gravity to drain fuel and solidify if external power is lost, and operating at atmospheric pressure to limit the risk of release beyond the site.
