Modern Nuclear Fuel Cycles
- MWD/MTU (megawatt days of energy produced per metric ton of uranium contained)
Energy produced per metric ton of uranium (fuel) contained. Current Nuclear Regulatory Commission limits for nuclear power plant fuel is 62,000 MWD/MTU. Normal lifetime of a fuel assembly is 55,000 MWD/MTU.
An ore with a very high UO2 content of up to 70%. Pitchblende also contains radium, thorium, cerium, and lead.
- The Department of Energy
Required by law to be responsible for the spent fuel and collects a fee of 1 mill/kWh of nuclear electricity for disposal.
- The US Nuclear Regulatory Commission (US NRC)
Regulatory body for radioactive materials and nuclear power plants.
More readily available nuclear fuel than uranium, being four times more abundant than uranium in the earth’s crust.
- Uranium dioxide (UO 2)
An insoluble oxide of uranium which is the form commonly used in commercial nuclear fuel.
Occurs in most rocks in concentrations of two (sedimentary rocks) to four...
