http://canteach.candu.org/Content%20Library/19990126.pdf 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… Web• The fourspecial safety systems are: => shutdown system number1 => shutdown system number2 => emergency core cooling system => containment system. • The reactor may … memphis nicest hotel
