Core Size Comparison CANDU 6 728 MWe 380 channels Diameter = 760 cm ( 299 inches) ACR 731 MWe 284 channels Diameter = 520 cm ( 205 inches) Calandria volume reduced by a factor of 2.5 (smaller lattice pitch). By using H2O coolant, less than 25% of D2O used in C6 is required. Pg 18
Effect of Trip Time & CVR on LOCA Transients in ACR LOCA power transients in ACR Not sensitive to trip time ( 1 to 3 seconds) Not sensitive to the magnitude of the negative CVR ( -1 mk to –6 mk) Pg 19
