3 AP1000 Plant Technology 2-loops, 2 steam generators reactor coolant system Familiar but improved reactor coolant system Larger pressurizer to eliminate the power operated relief valves Sealless reactor coolant pumps Simplified reactor coolant loops Compact 3415 MWt / 1117 MWe Plant Passive safety systems supplemented with simple, active defense-in-depth systems and equipment to provide multiple lines of defense 3 Safe, simple and standard

4 Major Safety Advancements of the AP1000 Plant Passive Safety-Related Systems Use passive processes only, no active pumps, diesels,. One-time alignment of valves No support systems required after actuation Greatly reduced dependency on operator actions Active Defense in Depth-Related Systems Reliably support normal operation Redundant equipment powered by onsite diesels Minimize challenges to passive safety systems Not necessary to mitigate design basis accidents Severe accident scenario effects are mitigated by in-vessel retention of the melted fuel All Critical Station Blackout Response Features FAIL SAFE 4

5 LCOE for Nuclear Power Plants The U.S. Energy Information Administration (EIA) published a capital cost estimate of $5500/kWe in the Analysis & Projections Assumptions to AEO2014 Electricity Market Module (Electricity Market Module) in APPENDIX D - EIA annual Energy Outlook The $5500/kWe cost translates to a price of approximately $12.5 billion for a twin-unit plant in the United States, which includes Owner s costs and the initial fuel load, and is consistent with publicly available AP1000 plant cost projections for a twin-unit nuclear plant. If a more detailed assessment is made relative to local requirements, Owner s scope, and site specific characteristics, a more relevant price/cost structure can be determined for Australia. However for initial assessment purposes, the $5500/kWe cost will provide a directionally correct estimate. The one adjustment recommended to the published cost data is removal of the 5 percent adder, titled Technological Optimism Factor, which is applied to only the first four units, and replacement of it with the initial fuel load cost, which is not included in the U.S. Government overnight costs. This adjustment does not impact the estimated total dollars per kwe. AP1000 Typical Plant Cost Breakdown, the $5,500/kWe is approximately 20% ($1000/kWe) Owner s cost and 80% ($4,500/kWe) EPC Contractor cost. The total project capital cost can be split into the three major categories: standard plant, site specific, and Owner s costs. Table depicts a standard AP1000 singleunit plant. 5
