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 fuels.

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 purpose;"
* "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
