Seth Grae

President and Chief Executive Officer

Seth has led the strategic direction and financing efforts of Lightbridge since its founding, including taking the company public. During his tenure, Lightbridge has evolved into a leader in developing advanced nuclear fuel technologies and in providing advisory services to developing and existing nuclear energy programs seeking to meet the highest international standards of safety, non-proliferation, and transparency.

He 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 non-emitting source of base load electricity.

Lightbridge also advises 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, and Seth and his family lived in Abu Dhabi during the procurement process for the initial four reactors. Lightbridge is engaged by domestic and overseas governmental entities on critically important civil nuclear advisory matters.

Prior to Lightbridge, he worked as a corporate attorney in New York. Seth is invited to guest lecture at universities and to speak at conferences on energy, nuclear power, and the environment.

Seth is a member of the Civil Nuclear Trade Advisory Committee (CINTAC) to the U.S. Secretary of Commerce and is a member of the Nuclear Energy Institute’s Board of Directors and Suppliers Advisory Committee. He is member of the Nuclear Security Working Group. He is also a member of the Dean’s Advisory Council at the Washington College of Law at American University. He has served as Vice Chair of the Governing Board of the Bulletin of the Atomic Scientists, as a 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 B.A. (cum laude) from Brandeis University; an M.B.A. and an L.L.M. in international law (with honors) from Georgetown University; and a J.D. from American University.
