Nuclear Waste Burning Reactor

Hlw arises from the burning of uranium fuel in a nuclear reactor.

Nuclear reaction and radioactive decay. Reducing the number of fresh nuclear fuel elements required and spent nuclear fuel elements generated while producing a given amount of energy. You like nuclear. The nuclear waste problem a typical 1000 mwe pwr reactor operating at 75 capacity generates about 21 tons of spent fuel at a burn up of 43 gwdt.

There are two distinct kinds of hlw. A plan to burn britains radioactive nuclear waste as fuel in a next generation reactor moved a step closer to reality on monday when ge hitachi submitted a thousand page feasibility report to the. Hlw accounts for just 3 of the volume but 95 of the total radioactivity of produced waste.

Besides in the twr itself that includes fast neutron reactors heavy water reactors like candu already commercialised and although not ideal even pressurised light water reactors. Hlw contains the fission products and transuranic elements generated in the reactor core. The deep burn modular helium reactor db mhr might reach 500 gwdt of transuranic elements.

Reactors can similarly burn existing nuclear wastes and are proliferation resistant. As a byproduct of burning fissile fuel fission reactors produce nuclear waste which can be converted in polonium pellets plutonium pellets or antimatter pellets. The 21 tons of spent fuel contained inside 42 pwr fuel elements with a total volume of about 11 m 3 will have produced an electric energy of about 66 twh 66 billion kwh.

Convert the plutonium waste into mixed oxide mox fuel and then burn the fuel in conventional pressurised water reactors. This would involve the construction of a second mox fuel plant at. Thorium can be used in several types of reactor.

The first two produce spent nuclear waste as a byproduct at a ratio of 110 while antimatter production is a completely clean process ie. Diagram of hitachis nuclear waste burning reactor system image. So do we.

In a power station high fuel burnup is desirable for. A new molten salt reactor design can scale from just 50 megawatts electric mwe to 1200 mwe its creators say while burning up nuclear waste in the process. Used fuel that has been designated as waste.
