The ACR-1000™ design has evolved from AECL’s in depth knowledge of CANDU® systems, components and materials based on the CANDU 6 design, as well as the experience and feedback received from owners and operators of CANDU plants. The ACR® design retains the proven strengths and features of CANDU reactors, while incorporating innovations and state-of-the-art technology. It also features major improvements in inherent safety characteristics, safety margin and operational performance. The ACR design has been reviewed by domestic and international regulatory bodies, and has been given a positive regulatory opinion about its licensability in Canada and internationally. The Canadian regulator, the Canadian Nuclear Safety Commission (CNSC) completed the Phase 1 [1] and Phase 2 [2] pre-project design reviews in December 2008 and August 2009 respectively, and concluded that there are no fundamental barriers to licensing the ACR-1000 design in Canada. The generic PSAR for ACR-1000 was completed in September 2009. The PSAR contains the ACR-1000 design details, the safety and design methodology, and the safety analysis that demonstrate ACR-1000 safety case and compliance with Canadian and international regulatory requirements and expectations. The final stage of the ACR-1000 design is currently underway including documentation and additional confirmatory analysis, and the basic engineering will be completed in 2011. This paper provides an overview of the ACR-1000 design including a summary of the safety methodology used and compliance with regulatory and customer requirements, along with a demonstration of how modern expectations on safety margins and operational performance (i.e., typically characterized as Generation III+) are met. It also provides a summary of the safety analysis results (both deterministic and probabilistic) from the generic safety analysis that has been completed.
