This feature is unique to CANDU reactors. After the 2nd year, the CANDU reactor begins to operate practically as a thorium burner.Very high burn-up can be achieved with the same fuel (>160,000 MW D/MT). CANDU reactors have two independent shutdown systems that can be actuated by the in-core reactor protection system and that are able to effect a rapid reactor shutdown. The incentive for such a study is the possibility of improving the uranium resource utilization and reducing costs. The acronym refers to its deuterium oxide (heavy water) moderator and its use of (originally, natural) uranium fuel.
