Thorium World Nuclear Association

A key finding from thorium fuel studies to date is that it is not economically viable to use low enriched uranium LEU with a U 235 content of up to 20% as a fissile driver with thorium fuels unless the fuel burn up can be taken to very high levels well beyond those currently attainable in LWRs with zirconium cladding

Thorium vs Uranium Power Engineering

It s also important to note that while thorium is fertile it is not fissile which means that the thorium fuel cycle requires a fissile material like uranium 235 or plutonium 239 to start the
