A US business venture funded partly by Bill Gates has secured additional funding for the proposed development of a 1,000-megawatt nuclear power reactor concept called the Travelling Wave Reactor (TWR).
TerraPower, based in Washington, said this week that it had raised more than 35 million US dollars (28 million euro) in a second round of financing. Venture capital firms Charles River Ventures and Khosla Ventures have joined TerraPower’s investors, which include Intellectual Ventures co-founder Nathan Myhrvold and Mr Gates.
TerraPower says the TWR concept could operate for up to 100 years without refuelling or removing any used fuel from the unit. The concept uses ideas that date back to the 1950s for using non-enriched or even depleted uranium-238 as a nuclear fuel, breed-burn core designs and the use of a deflagration.
