The CANDU includes a number of active and passive safety features in its design. Some of these are a side effect of the physical layout of the system. CANDU designs have a positive void coefficient, as well as a small power coefficient, normally considered bad in reactor design. This implies that steam generated in the coolant will increase the reaction rate, which in turn would generate more steam. This is one of the many reasons fo… WebApr 12, 2024 · A Canada Deuterium Uranium (CANDU ®) nuclear reactor is a Canadian reactor that uses pressurized heavy water to produce electricity [1,2,3,4,5,6,7,8,9]. To ensure the safety and reliability of the reactor for operation, various systems, including the fuel channels, are continually inspected.
