An isolation condenser (IC) system capable of transporting the total energy produced in the reactor core due to decay heat was designed and modeled. greenslopes private hospital gynaecologyThe 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.
