2 2 President Obama’s Nuclear Energy Goals “Thanks to the ingenuity of our businesses, we're starting to produce much more of our own energy. We're building the first nuclear power plants in more than three decades in Georgia and South Carolina.“ -Georgetown University June 26 th, 2013 “Now, one of the biggest factors in bringing more jobs back is our commitment to American energy. The all-of-the-above energy strategy I announced a few years ago is working, and today, America is closer to energy independence than we’ve been in decades.” - State of the Union, January 28th, 2014

3 3 “The Energy Department is committed to strengthening nuclear energy’s continuing important role in America’s low carbon future, and new technologies like small modular reactors will help ensure our continued leadership in the safe, secure and efficient use of nuclear power worldwide.” New Investment in Innovative Small Modular Reactor, December 12, 2013 “All-of-the-above is not merely a slogan, but a clear-cut pathway to creating jobs and at the same time reducing carbon emissions, which recently stood at their lowest level in 20 years… President Obama has made clear that he sees nuclear energy as part of America’s low carbon energy portfolio. And nuclear power is already an important part of the clean energy solution here in the United States.” The National Press Club, February 19, 2014 Secretary Moniz on Nuclear Energy

4 4 Secretary Moniz Announces $6.5 Billion Vogtle Loan Guarantee “The construction of new nuclear power facilities like this one - which will provide carbon-free electricity to well over a million American energy consumers - is not only a major milestone in the Administration’s commitment to jumpstart the U.S. nuclear power industry, it is also an important part of our all-of-the-above approach to American energy as we move toward a low- carbon energy future… The innovative technology used in this project represents a new generation of nuclear power with advanced safety features and demonstrates renewed leadership from the U.S. nuclear energy industry.” Construction of Vogtle Unit 3, January 2014 ©Georgia Power Company

19 19 Nuclear Energy University Programs The Nuclear Energy University Programs (NEUP) and the Integrated University Program (IUP) have a well established competitive process for awarding R&D, infrastructure and scholarships/fellowships.  The Office of Science and Technology Innovation will continue implementing this competitive process and will expand to incorporate it into all competitive research. The NE R&D Programs are the cognizant technical managers of these competitive R&D awards and therefore play in integral role in the success of each project.  Universities, national laboratories, industry, and foreign research partners are strongly encouraged to actively engage and collaborate with the NE R&D programs. Since FY09, NEUP and IUP have awarded $290M to 89 schools in 35 States and the District of Columbia.

20 20 Impact of Early Retirements on Clean Energy Goals Consider Dramatic Retirement Scenario  One-third of the reactor fleet, ~26 GW, 200 TWh/yr  Replacement power estimated to add 125 MT per year Near-term Target: Reduce Emissions 17% by 2020  2005 emissions from power sector: 2,417 MT  Reduction target of 411 MT climbs to 536 MT (30% increase) Long-term Target: 80% Clean Electricity by 2035  Need 2,900 TWh non-emitting power; EIA: 800 TWh of nuclear, 700 TWh of renewable  1,400 TWh shortfall grows to 1,600 TWh with retirements Meeting energy goals will be challenging. Retiring nuclear plants early makes the challenge more daunting.
