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 that built Shippingport, the world's 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 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.

Alvin Radkowsky (1915-2002)
Dr. Alvin Radkowsky, inventor of Radkowsky Thorium Power Corporation'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 graduated from New York University with a B.A. in 1954 and received his J.D. from New York University Scholl of Law in 1958. He is a member of the New York Bar.

During his career he has acted as attorney and business consultant to a number of multi-national consortia and companies. These range in scope from negotiating the purchase of large real estate tracts in New York City to starting a rice trading company in the Middle East. In addition, Mr. Grae negotiated the purchase of and was involved in the management of a 5,000-acre working farm in Alamosa, Colorado. Mr. Grae was also a Partner in the Riposanu, Leibowitt & Grae law firm in New York City.

In 1992 he co-founded Radkowsky Thorium Power Corporation with Dr. Alvin Radkowsky to commercialize inventions of Dr. Radkowsky. Mr. Grae acted in the capacity of President from 1992 to 1997. It was under his administration that the original patents were issued and work began in Russia.

Mr. Grae has a long history of working with and sponsoring medical and scientific research and scientific projects at leading institutions including Yale University, Cornell University, Rensselaer Polytechnic Institute, Clemson University, and The New York Presbyterian Group. He has been issued five patents by the U.S. patent office that have been assigned to Milli-Second Technologies Corp., where he serves as a Director. He also founded MelaRx, a company involved in tumor targeting and other companies.

Mr. Grae currently is the Managing Partner in Aviex Technoloies, LLC, a company developing a new platform technology to produce an administer influenza vaccines and Amalgamated Technology Transfer, LLC, a company active in the development of a new homogeneous plastic composite.

Throughout his career, Mr. Grae has integrated his knowledge of law and science with the formation of numerous entrepreneurial enterprises. He continues his active interest in projects that promote the public good. Additionally, Mr. Grae is an avid art collector and benefactor to numerous cultural venues. He and his wife SusAnna in 2010 donated a major African antiquity collection to Yale University. Mr. Grae has three children and five grandchildren.
