The Sodium Reactor Experiment
In February 1957, construction was completed on the Sodium Reactor Experiment (SRE), a sodium-cooled, graphite-moderated reactor with an output of 20 MWt. The design of theSRE had begun three years earlier in 1954, and construction started in April 1955. On April 25, 1957, the reactor reached criticality, and the SRE operated until February 1964.

COP28 is being called by some "The Nuclear COP" and the American Nuclear Society wants to dive into how and why this COP saw such prominence for our industry and one of our world's most significant clean energy technologies. Join ANS CEO/Executive Director Craig Piercy, as he discusses the pivotal international event with expert participants that were on the ground at COP28 and in the rooms where historic pledges and agreements related to nuclear energy were created.

Seth leads Lightbridge’s efforts to develop and deploy advanced nuclear reactor fuel that will result in more electricity being provided from existing and new reactors, as well as enhanced safety and proliferation resistance, to allow nuclear power to compete and grow internationally as a clean source of base load electricity.
Lightbridge has also advised governments of countries seeking to start nuclear power programs from feasibility studies through procurement and operations. Lightbridge’s first major international engagement was to develop the strategic plan—the Roadmap for Success—for commercial nuclear energy for the United Arab Emirates.
Seth is a member of the Civil Nuclear Trade Advisory Committee (CINTAC) to the U.S. Secretary of Commerce, Nuclear Energy Institute’s Board of Directors, American Nuclear Society’s Trustees of Nuclear Leadership Council, Working Group on Climate, Nuclear, and Security Affairs of the Council on Strategic Risks, and Board of Directors of the Virginia Nuclear Energy Consortium. He is also a member of the Dean’s Advisory Council at the Washington College of Law at American University. He has served as a member of the Nuclear Security Working Group, Nuclear Energy and National Security Coalition, Vice Chair of the Governing Board of the Bulletin of the Atomic Scientists, member of the Board of Directors of the Lawyers Alliance for World Security, and as Co-chair of the American Bar Association’s Committee on Arms Control & Disarmament.
Seth earned a BA (cum laude) from Brandeis University, an MBA and an LLM in international law from Georgetown University, and a JD from American University.
Jeremy is the Chief Strategy Officer at ClearPath, a research and advocacy organization focused on policies that accelerate innovations to reduce and remove global energy emissions. As CSO, he leads the development, management, and execution of the organization’s strategic plan.
In addition to his role at ClearPath, Jeremy is a member of the U.S. Department of Commerce’s Renewable Energy and Energy Efficiency Advisory Committee (REEAC). He also serves in leadership roles at multiple clean energy industry trade groups, including Chair of the U.S. Nuclear Industry Council’s Board of Directors. He is a frequent commentator on clean energy innovation, export financing, and regulatory reforms that accelerate the development of cutting-edge technologies at industry convenings and trade shows, and is frequently featured in national publications including The Washington Post, Politico, Bloomberg, The Hill, GreenBiz, and S&P Global, among others.
Before joining ClearPath, Jeremy advised Congressional leaders, across multiple roles in the House and Senate, on energy, environmental, natural resources, tax, and transportation policy for a decade.
He received his BA in Political Science and History from Miami University in Oxford, Ohio and an MBA from New York University’s Leonard N. Stern School of Business.
