Once-through fuel cycle

In this approach, natural uranium is converted to low-enriched uranium (LEU) oxide fuel. Power plant operators then use the fuel to generate electricity in a standard light water cooled nuclear reactor before sending the fuel directly to storage and geologic disposal. The once-through fuel cycle is the basis upon which all other fuel cycle approaches are compared in this calculator.
