Past, present, and future of nuclear power in U.S

'Full text:' Over the past two decades, nuclear power has reliably and economically contributed approximately 20 percent of electrical generation in the United States. It remains the single largest contributor (about 60 %) of non-greenhouse gas emitting electric power generation in the United States. Domestic demand for electrical energy is expected to grow at an average rate of 1 percent per year. As a part of President Obama's Climate Action Plan 'The United States will continue to promote the safe and secure use of nuclear power worldwide through a variety of bilateral and multilateral engagements. For example, the U.S. Nuclear Regulatory Commission advises international partners on safety and regulatory best practices, and the Department of Energy works with international partners on research and development, nuclear waste and storage, training, regulations, quality control, and comprehensive fuel leasing options. Going forward, we will expand these efforts to promote nuclear energy generation consistent with maximizing safety and nonproliferation goals.' This talk will outline the current status and challenges facing nuclear energy in the United States and specifically, how the Office of Nuclear (NE) supports the advancement of nuclear power as a resource capable of making major contributions in meeting our Nation's energy supply, environmental, and energy security needs.
