Evolutionary innovation approach is adopted for the ACR design, it is soundly based on the proven CANDU essential features and associated development flexibilities, while some enabling technologies and new design features are creatively incorporated, including a tight lattice core with the use of slightly enriched uranium fuel and light water coolant. This allows ACR to combine the best of advanced heavy water reactors and advanced light water reactors.
