Wie funktioniert ein Laufwellenreaktor?
Ein Laufwellenreaktor (englisch traveling-wave reactor, TWR) ist ein theoretisches Konzept eines Kernreaktortyps, der Brutmaterial in spaltbares Material umwandelt (Erbrütung). Der TWR unterscheidet sich vom schnellen Brüter dadurch, dass er mit wenig oder gar keinem angereicherten Uran auskommt.
Für was braucht man Reaktoren?
Dagegen dienen Forschungsreaktoren zur Erzeugung von freien Neutronen, etwa für Zwecke der Materialforschung oder zur Herstellung von bestimmten radioaktiven Nukliden für medizinische oder ähnliche Zwecke.
How safe are TerraPower’s nuclear power plants?
And TerraPower’s Natrium Reactor plants will be safer still, thanks in large part to a more reliable cooling system for its reactors. Nuclear fission, a process where atoms split and release a large amount of energy, generates a lot of heat.
What is Terra power technology?
TerraPower is a nuclear reactor design company headquartered in Bellevue, Washington, United States. TerraPower is developing a class of nuclear fast reactors called the traveling wave reactor (TWR). The TWR concept places a small core of enriched fuel in the center of a much larger mass of non-fissile material, in this case depleted uranium.
What is Terrapower’s test facility?
TerraPower’s test facility is where the company does full-scale physical testing for fuel handling operations. Beyond that, TerraPower’s cooling system does not rely on any outside energy source to operate in the event of an emergency shutdown of a reactor.
What is Terrapower’s advanced reactor demonstration program?
Selected by the U.S. federal government to demonstrate the viability of nuclear power through its Advanced Reactor Demonstration Program (ARDP), TerraPower aims to build “fully functional advanced nuclear reactor within 7 years of the award,” according to the Office of Nuclear Energy at the U.S. Department of Energy.
