NUCLEAR FUEL BUNDLE CONTAINING THORIUM AND NUCLEAR REACTOR COMPRISING SAME

摘要

The present invention provides a fuel bundle for a nuclear reactor, in some embodiments, comprising: a first fuel element comprising thorium dioxide; A second fuel element comprising uranium with a first fissile content; And a third fuel element comprising uranium having a second fissile content different from the first fissile content. The present invention also discloses a nuclear reactor using the fuel bundle, including a pressurized heavy water reactor. Uranium with different fissile content may include combinations of natural uranium, depleted uranium, recycled uranium, slightly enriched uranium and low enriched uranium.
