CANDU (Canadian Deuterium Uranium)

CANDU, which stands for Canadian Deuterium Uranium, is a type of nuclear reactor designed in Canada. It uses heavy water (deuterium oxide) as a coolant and neutron moderator, allowing it to efficiently burn natural uranium fuel without needing enrichment. This design contributes to safety and flexibility in operation, as CANDU reactors can be refueled while they are still running. CANDU technology is notable for its ability to utilize various fuels, including recycled nuclear waste, making it a potentially sustainable option in nuclear energy production.
