Independent Study Validates Non-Proliferation Benefits of Lightbridge's Proprietary Metallic Fuel

Independent Study Validates Non-Proliferation Benefits of Lightbridge's
Proprietary Metallic Fuel

MCLEAN, Va., March 21, 2013 (GLOBE NEWSWIRE) -- Lightbridge Corporation
(Nasdaq:LTBR) today announced that an independent analysis by Pace Global, a
Siemens (NYSE:SI) business, confirms the Company's patented metallic fuel
design has superior non-proliferation benefits compared to current nuclear

According to the report, the reasons for the superior non-proliferation
benefits include:

  *"The amount of residual plutonium [at the end of the fuel's useful life]
    is significantly smaller in the Lightbridge designs" and there are "large
    fractions of neutron [absorbing elements] in Lightbridge metallic fuel"
    that would poison an attempt to make an explosive device from the
  *Any attempt to reprocess spent Lightbridge fuel would require "additional
    complex chemical processing of the metallic portion of the fuel," and "it
    is believed no industrial-scale process has been developed for this
  *"Current U.S. reactor fuels and the proposed Lightbridge design are all
    classified as LEU (low enriched uranium)" that "cannot be used directly
    for the construction of nuclear weapons." "If a diverter had the necessary
    access to enrichment facilities, it would actually be more efficient and
    stealthy for the [diverter] to process natural uranium to the highly
    enriched state," as opposed to processing LEU.

"We are pleased by this independent confirmation of the fuel's significant
non-proliferation benefits and by the steady achievement of technical
milestones on the way to regulatory approval and commercialization of our
fuel," said Seth Grae, Lightbridge President and CEO.

A December 2012 Pace Global analysis of Lightbridge fuel concluded that
"Lightbridge's metallic fuel can deliver significantly improved economics to
nuclear utilities from increased power output and extended fuel cycles,
resulting in highly attractive returns on invested capital, even with
conservative assumptions on reactor conversion and regulatory licensing costs,
and fuel technology licensing fees paid to Lightbridge," Grae added.

The Pace Global non-proliferation and economic analyses follow the recent
publication of a peer-reviewed article that highlights how the Company's next
generation fuel is capable of increasing the power output and extending the
fuel-cycle length of light water reactors. The article also reviews the unique
geometry and composition of the metallic fuel and its application to power
uprates in light water reactors. The article was published in the December
2012 edition of Nuclear Technology, a publication of the American Nuclear
Society. An abstract of the article is available at
