Plant Safety, Performance, and Economics
Steadily Improving
 Excellent plant management and operational experience
 Well-developed safety culture and effective regulation
 Lowest production costs for fueled-generation
Nuclear Capacity Factor
Is at an All-Time High
Performance improvement is equivalent to
adding 17 more gigawatts since Watts Bar 1
in 1996.

Electricity production costs do not include capital. For a new plant
construction add at least 20 – 30 mills/kWh to cover capital investment for
both nuclear and coal.

Nuclear Energy Plays an Important Role Today
U.S. Electricity Consumption
 Nuclear power is clean, reliable base load energy
source
• Provides 19% of U.S. electricity generation mix
• Provides over ⅔ of U.S. emission-free electricity
• Avoids about 700 MMTCO2 each year
• Helps reduces overall NOx and SOx levels

 Unacceptable Risks Identified
• Regulatory Uncertainty
• Litigation Risk
• Economic Competitiveness of First Plants
» Long Construction Durations
» Higher Capital Costs for Early Plants
 Power companies are unwilling to increase
their market capitalization by a significant
percentage to build new nuclear plants
DM#181900 NARUC 4
Nuclear Power 2010 … Demonstration Program to
Deploy New Nuclear Power Plants
 Program initiated in February 2002
 Focused on addressing regulatory,
financial, and technical challenges
 Based on Near-term Deployment
Roadmap and other studies
 Government/industry cooperative
effort
• 50-50 cost-shared industry projects
• Market-driven
DM#181900 NARUC 5
Nuclear Power 2010 … Program Scope and Goal
 Exploring sites for new nuclear plants
 Demonstrating key untested regulatory processes
• Early Site Permit (ESP)
• Combined Construction and Operating License (COL)
 Developing new light water reactor designs
• Design Certification for new reactors
• First-of-a-kind engineering (FOAKE) for new
standardized nuclear plant designs
 EPACT 2005 Incentives
• Loan Guarantee
• Standby Support Delay Risk Insurance
• Production Tax Credit for Advanced Nuclear Reactors
Program
Goal
Pave the way for industry decisions to build new advanced light water
reactor nuclear plants in the United States that will begin operation early in
the next decade.
DM#181900 NARUC 6
EPAct, Title XVII, “Loan Guarantees”
 Purpose
• Government support needed—financial risk to first movers too great
» Market capitalization of power companies too small any to add so much more equity to
balance sheet
 Process
• Solicit applications from project sponsors
• Due diligence review assesses risk
• Issue Term Sheet
• Sponsor pays subsidy cost and guarantee granted
 Authority
• Consolidated Appropriations Act, 2008 granted time-limited (through FY 2009) loan
guarantee authority for $18.5 billion for nuclear power project and $2 billion for
nuclear fuel cycle projects
» If COL approval is a condition precedent, no project would be ready before FY 2010
» FY 2009 budget requests an extension of authority with same ceilings through FY 2011
 Status
• Final Rule issued on October 4, 2007
• Earliest practical date for nuclear solicitation: 4/15/08
 For more information: www.LGprogram.energy.gov
DM#181900 NARUC 7
EPAct, Section 638, “Standby Support”
Indemnification against delays for six new advanced nuclear reactors:
• Failure of NRC to comply with scheduled reviews and approvals
• Certain litigation that delays commencement of full-power operation
Covered Costs
• Initial two reactors: 100% of covered cost of delay up to $500M per contract
• Subsequent four reactors: 50% of covered cost of delay up to $250M per
contract after initial 180-day delay
Department issued final rulemaking in August 2006
Two Step Process: Conditional Agreement (Step 1), then Standby Support
Contract (Step 2)
Released Standard Conditional Agreement September 2007
Released Agreement Instructions in December 2007
Schedule
First Standby Support Conditional Agreements with industry expected in
2008

EPAct, Section 1306, “Production Credit”
(Section 45J of IRS code)
 Improves project internal rate of return by
reducing tax burden over first 8 years of
facility operation
 National megawatt limitation of 6,000
megawatts will be allocated to eligible
projects
 Allocation:
• COL application before 2009
• Construction begins before 2014
• Placed in service before 2021
 1.8¢ per kilowatt-hour, but limited to a maximum of $125 million per 1,000
megawatts allocated per year
 Treasury issued IRS Notice on production credits in May 2006 with
guidelines for allocation and approval process
 Currently evaluating need to issue clarifying regulations for claiming
production tax credits for new nuclear capacity

Advanced Reactor Designs Under Consideration
 GE-Hitachi ABWR – NRC Certified (1997)
 Westinghouse AP1000 – NRC Certified (2005)
 GE-Hitachi ESBWR – Under NRC Review
 AREVA US-EPR – Under NRC review
 Mitsubishi US-APWR – Under NRC Review
DM#181900 NARUC 11
Benefits of Advanced Reactor Designs
 Standardization
• Easier to operate
• Faster and cheaper to build, operate and maintain
 Simpler and Safer
• Latest technology
• Less equipment and components
• Passive safety systems (AP 1000 and ESBWR)
• Simplified operations and maintenance
 Larger Scale
• Range from 1100 to 1700 MW
 Operating or under construction elsewhere

Generation III—ABWR, EPR, and USAPWR
 Larger plants/greater capacity
• US-EPR – 1600 MWe
• US-APWR – 1700 MWe
 Improved plant efficiencies
• US-EPR – 37%
• US-APWR – 10% more than APWR
 Improved safety features
• EPR has double containment for ensuring safety
 Flexible fuel cycles (up to 24 months)
 ABWR operating in Japan since 1996
DM#181900 NARUC 15
Generation III+ Design Objectives
 Standardized designs
 Simplicity and small plant sizes
 Increased plant design life – 60 years
 Reduced costs – larger plant rating or
simplifications
 Shorter construction schedules
 Passive safety systems
 Increased plant safety features
 Digital I & C provides reliable and accurate plant
monitoring and control
 Improved seismic responses
 Less equipment and components
 Simpler operation and maintenance
DM#181900 NARUC 16
Advanced Passive Designs
 AP1000 and ESBWR
• Rely on natural forces to increase safety
• Improved automatic safety features
• Substantially reduce size, equipment, and components
• Simplicity and small plant size
• Significantly less construction time
DM#181900 NARUC 17
DOE Loan Guarantee Program
 Considered most important of EPACT incentives for new nuclear plants
 Only incentive that can reduce cost of money
• Allows lenders to offer significantly
lower interest rate, reducing cost of
plant by 10 to 15 percent
• Production Tax Credit provides positive
cash flow after reactor is in operation;
cannot alleviate financial risks during
construction
• Standby Support, because it provides
limited protection for lenders, cannot
significantly lower debt interest rate
 Power companies unable to
increase their market capitalization
by significant percentage to build
new nuclear plants
• Would not go forward without loan
guarantees
Source: Nuclear Energy Institute
 All plants of each reactor technology will need loan guarantees until proven track record
established—3 operating plants of each reactor technology

 Today, without incentives, nuclear plant would have higher generation cost than
pulverized coal or natural gas combined cycle
 With learning, nth nuclear plant has lower generation cost than integrated gas
combined cycle or natural gas combined cycle with carbon capture
 We never get to lower cost nth nuclear plant unless first few are built
• EPAct incentives make first nuclear plant less expensive than IGCC or natural gas CC with
carbon capture
