The ABWR is unique relative to other advanced nuclear designs given that it is already certified by the U.S. Nuclear Regulatory Commission and has an established track record of commercial viability. The chart below provides a comparison of ABWR and other major advanced nuclear designs.

Advanced Nuclear Designs		ABWR	EPR	APWR	ESBWR
Designed	Eliminates need for design changes in the field Ensures engineering remains ahead of construction schedule Certainty in performance versus theoretical or calculated
Supply Chain Established	Proven supply base   Design and manufacturing process established Components proven to meet unit specifications Lead times and cost estimates are known Mitigates multiple first-of-a-kind risks that increase cost and schedule
Constructed	Four operational units built in Japan within 37-43 months Known quantities of labor, material and equipment Proven unit modularization has increased modularization more than 100% from first units Integrated team with substantial experience in ABWR construction
Operated	More than 12 years operating experience Achieved capacity factors of more than 92% Known O&M and CapEx costs Startup and early operational issues identified and mitigated
