Benefits of the Westinghouse SMRProven Technology Basisgy
• Passive safety systems are conceptually similar to AP1000® plant (proven design)
• Digital I&C systems based on AP1000® plant design (provenDigital I&C systems based on AP1000 plant design (proven design)
• Only SMR designer with an approved fuel designO t ith h d t (l ti i k)• One reactor with no shared systems (less operating risk)
• Large, predictable thermal margin of safety• Pump-Driven RCS flow at power results in increased plant p p p
efficiency and increased core cooling certainty during power operations
• Yields the most power with the least amount of material andYields the most power with the least amount of material and equipment
• Fully-modular nuclear generating station design
