Trends and Accomplishments in the US Department of Energy Nuclear R&D Program
The Present – Nuclear Energy in the U.S.
Excellent record of safety and
production
All plants expected to be operable for at
least 60 years and possibly to 80 years
20 license applications for 31 new
reactors are expected
Construction depends on financing
– Loan guarantees
• Award $8B for first 2 Southern Company
Plants
• Increase authority to $50B
– Regulated markets
Focus on near-term deployment
of advanced ALWRs, extending
the life of existing reactors and
on R&D for advanced reactor
and fuel cycle technologies
104 reactors supply 20% of electricity,
operating in 31 states
70% of emissions-free electricity is nuclear,
displacing the equivalent of annual CO2
from U.S. cars
1/10 of light bulbs in U.S. are powered from
HEU down-blended from Russian warheads
Nuclear energy is safe because of
redundant systems, automatic shutdown
systems and multiple layers of separation
2
A Decade of Uncertainty in Energy Markets, Investment, and Policies Consumption and investment have
been impacted by the economic
recession
Falling investment could lead to a
future spike in energy prices after the
economy recovers
3
World Energy Outlook, 2009
Outlook for nuclear and renewables is mixed – Stimulus efforts are offsetting some of the decline, particularly wind
– Borrowing is difficult
– Cost of capital is higher
Future outlook depends on continuity of policies
Adjustments will be needed to increase accident tolerance
US Administration is seeking new options for nuclear waste
– Yucca Mountain reality
– Modern strategy based on extended storage and new technologies, followed eventually by a closed fuel cycle

Safety: Enhanced passive safety
– For example, natural circulation cooling reduces threats from
loss of site power
Potentially simplified licensing process
– Possibly smaller emergency planning zone
– DOE Office of Nuclear Energy has proposed a
program that would accelerate licensing of SMRs
Possibility of DOE and/or DOD siting of first units
R&D Focus Areas: – SMR Instrumentation, Controls & Human Machine Interface
– SMR Assessment Methods

Nuclear Energy Advanced Modeling and Simulation (NEAMS)
NEAMS will rapidly create and deploy next generation modeling and
simulation capabilities – Development of new tools will be needed to support design, implementation, and
operation of future nuclear energy systems
Modeling and simulation can potentially accelerate technology
development, improve fidelity of research findings, and facilitate
design certification – Validation of models and completeness of assessments are critical
– Modeling and Simulation may not be appropriate for all issues and questions -
experiments, demonstrations, and prototypes may be required in some instances

Example: AMP and Moose-Bison-Marmot
(MBM)
– AMP: Focused on engineering scale simulations of fuel assemblies
– MBM: Focused on atomistically-informed meso-scale simulations of microstructure evolution and engineering scale simulations of pellets/pin

• U.S. and China are the largest consumers of energy and producers of carbon dioxide
• China operates 11 nuclear power plants, representing 2 percent of electricity supply, and 14 units under construction, and 10 planned to start construction this year.
• The U.S. has 104 operating plants, 1 under construction (TVA Watts Bar 2), 17 applications for 26 new plants filed with NRC
• China technology provided initially by France and Russia; US developed original PWR technology that was exported to France and around the world
Sanmen 1, 1100 AP1000 PWR, under construction, China
Diablo Canyon, 2 Westinghouse PWRs operating, U.S.
China and U.S. share similar patterns of demand, supply growth, and sustainability
• Rapid growth, reliance on coal for electricity and heat, need and pursuing everything
• Both countries heavily reliant on oil, and this will not change; both seek to green coal
• China slow to start its civil nuclear program but with ambitious plans — 70 GWe operating by 2020 and 30 more GW in construction
• US grew its civil nuclear program in a short burst , slowed in 1979, and today, a resurgence/ US developed the PWR technology that is in use in most of the world today
• Nuclear cooperation agreement agreement approved by Congress in 1998, 13 years after proposed
