El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

Biographies
Seth Grae
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 Harrell
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.
Elina Teplinsky
Elina, Pillsbury’s Global Energy Industry Leader, Hydrogen Practice co-leader and a leading member of the firm’s International Nuclear Projects team, focuses on global nuclear and hydrogen energy matters. Elina is a trusted advisor to nuclear owner-operators, reactor and equipment suppliers, investors, architect-engineering companies and technical consulting firms on complex nuclear and hydrogen transactional and regulatory matters.
