Lightbridge Corporation is a nuclear energy pioneer developing proliferation resistant fuel technology and offering integrated advisory services for existing and emerging nuclear programs. The Company's mission is to establish a new standard in global nuclear power generation based on a core philosophy of transparency, non-proliferation, safety and operational excellence.

Our Company History

In 1992 Lightbridge Corporation was formed to develop and deploy nuclear fuel designs developed by Dr. Alvin Radkowsky, one of the founding fathers of the U.S. nuclear industry and one of the industry’s most respected nuclear engineers. Dr. Radkowsky, formerly head of the U.S. Navy Nuclear Propulsion Program, was a key member of the design team that built Shippingport, the world’s first first full-scale commercial nuclear power plant, and supervised more nuclear fuel core designs that were implemented and successfully operated than any other nuclear engineer in the history of the industry. A true pioneer, Dr. Radkowsky also sought to sever the link between nuclear weapons and nuclear power, and he developed thorium-based nuclear designs which would not produce weapons suitable plutonium in nuclear spent fuel.

To help realize Radkowsky's vision, Lightbridge Corporation went to Russia in 1994 and collaborated with nuclear scientists and engineers at the prestigious "Kurchatov Institute" research center. Since the original invention by Dr. Radkowsky, the technology initially underwent extensive scientific development and evaluation, and has now for over four years-been in the engineering development phase, including technology scale-up in a live research reactor. The company is now focused on advanced testing and commercialization of the technology.

Lightbridge Corporation's development and testing has followed standard industry protocols and is embarking on the next phase accelerating activities leading to the demonstration of Lightbridge Corporation's fuel technology in lead-test assemblies for use in a full-size commercial reactor - the final technology development phase before commercial deployment into multiple power plants.


Intellectual Property:

Lightbridge Corporation's nuclear fuel designs are protected by U.S. patents and their foreign equivalent in several countries. We are continuously analyzing new intellectual property as it comes out of our research and development activities to ensure all inventions are protected either through patents or trade secrets. The Company is currently implementing a program to expand the patent portfolio.

Co-founder Profiles

Original co-founders of Thorium Power, Inc. in 1992

Alvin Radkowsky (1915-2002)

Dr. Alvin Radkowsky, inventor of Thorium Power's original fuel design and a pioneer nuclear scientist, initiated and supervised more nuclear core designs which were actually built and successfully operated than any other nuclear engineer in history. He was a member of the prestigious US National Academy of Engineering and a fellow of both the American Physical Society and American Nuclear Society. At the end of 2001, Dr. Radkowsky was awarded the Alvin M. Weinberg Medal for outstanding international technical and policy leadership in nuclear science and technology. It was given to him as recognition for his "seminal contributions and innovations in the engineering development of nuclear power."

Dr. Radkowsky was the original Chief Scientist for the US Naval Nuclear Propulsion Program directed by the late Admiral H.G. Rickover. Dr. Radkowsky headed the design teams for the US Navy's nuclear submarines, aircraft carriers, and other surface ships. He also headed the design team for the first commercial nuclear power plant, in Shippingport, Pennsylvania.

He received a special award from the Secretary of the Navy for an invention that increased the endurance of the Nautilus submarine prototype from a few weeks to many years. This invention has been declassified and is used in virtually all commercial reactors.

Alvin Radkowsky received his Master's Degree at George Washington University under Professor Edward Teller, and his Ph.D at Catholic University of America under Professor Karl F. Herzfeld.

Dr. Radkowsky passed away on February 17, 2002.

Joel B. Grae

Joel B. Grae has built his career around starting high- technology companies and building them to the point of commercialization. He co-founded Thorium Power with Alvin Radkowsky. He has also acted as attorney and business consultant to foreign multinational consortiums and companies.

Mr. Grae has sponsored biotech research at major universities, including Yale, Cornell and Rensselaer Polytechnic Institute. He founded MelaRx Pharmaceuticals, Inc. as a privately-held company to support research at Yale and was its Vice President of Technology from 1992 until MelaRx merged with Vion Pharmaceuticals, Inc. (formerly OncoRx Pharmaceuticals, Inc.) in 1995. Vion is now a publicly traded company.

Mr. Grae is a graduate of New York University School of Law and is a member of the New York Bar.
