How much uranium is needed for a nuclear reactor?
About 27 tonnes of uranium – around 18 million fuel pellets housed in over 50,000 fuel rods – is required each year for a 1000 MWe pressurized water reactor. In contrast, a coal power station of equivalent size requires more than two and a half million tonnes of coal to produce as much electricity.
How many megawatts is a nuclear submarine?
“The power of a nuclear-powered submarine is around the 150-200 MW thermal power,” says Irwin. “For comparison, a very large power generator is about 3400 MW, generating about 1100 MW of electrical output.
How much power does a nuclear submarine reactor produce?
 To shift its immense weight of 100,000 tonnes, the US Navy has equipped it with two A1B nuclear reactors, each capable of producing 300 MW of electricity. But it’s not just about providing the power it needs today.
How much uranium is in a submarine?
Natural uranium mined from the ground consists mainly of an isotope called uranium-238, mixed with small amounts (0.7\%) of the key isotope uranium-235. For the reactor to work, the uranium fuel has to be “enriched” to contain the desired proportion of uranium-235. For submarines, this is typically about 50\%.
What is the power output of a nuclear submarine reactor?
-The reactor power is minimum 200 MW. -The fuel is highly enriched uranium, 90\% to 96\% enrichment and enough of it is in there to last the 25 year minimum lifetime of the sub. In other words unlike other reactors, sub engines never need refueling. There is no official data that I have seen but there are bits and pieces here and there.
How long does the fuel last in a nuclear submarine?
-The fuel is highly enriched uranium, 90\% to 96\% enrichment and enough of it is in there to last the 25 year minimum lifetime of the sub. In other words unlike other reactors, sub engines never need refueling.
How many tons of uranium are in a nuclear reactor?
For a reactor with an output of 1000 megawatts (MWe), the core would contain about 75 tonnes of low-enriched uranium. A typical thermal reactor contains about 100 tons of uranium with an average enrichment of 2\% (do not confuse it with the enrichment of the fresh fuel, that is about 4\%).
How many engines does a submarine have?
-US submarines have one engine. Soviet submarines usually have two. -The reactor power is minimum 200 MW. -The fuel is highly enriched uranium, 90\% to 96\% enrichment and enough of it is in there to last the 25 year minimum lifetime of the sub.
