International Isotopes "Green" Technology Depleted Uranium Project Remains on Course

IDAHO FALLS, Idaho, March 28, 2011 /PRNewswire/ -- International Isotopes Inc. (OTC Bulletin Board: INIS), issued a statement on March 17 emphasizing that the recent problems at Japan's nuclear power plants, as a result of a devastating earthquake and tsunami, have not changed the Company's plans to build the first commercial, environmentally friendly, depleted uranium de-conversion facility in the United States.  The Company would like to reiterate that the recent termination of its plans to complete an underwritten public offering of common stock was heavily influenced by the devastating events in Japan which for the time being made investors reconsider investments in businesses operating within the nuclear fuel cycle.  The termination of the Company's offering does not impact any of its near term plans for the proposed facility.

Steve T. Laflin, Company President and CEO, stated, "Investors should not confuse the events in Japan as a sign that our Company has, in any way, changed our plans or expectations for the commercial success of our depleted uranium processing facility.  We firmly believe that recent events do not affect the need for our proprietary solution to safely address depleted uranium and to produce useful products from that material.  Although the Company requires significant additional capital to complete construction of the planned depleted uranium de-conversion facility, it has sufficient cash on hand to continue near term planning and will continue to drive the project forward."

"In our March 17 news release we suggested that we did not believe that the events in Japan were likely to have any impact on commercial activities at the front end of the uranium fuel cycle.  In fact, in recent days, multiple companies involved in uranium ore production, uranium conversion, and uranium enrichment have publically expressed their continued optimistic views of the uranium sector.  Our Company's de-conversion services will exclusively address the front end of the nuclear fuel cycle in the United States.  Our business plan does not require a single new reactor to be built in order for it to be successful, and since there presently is no commercial uranium de-conversion option available in this hemisphere, we believe that there is a clear need for the services we intend to offer. Our patented Fluorine Extraction Process will produce important products from the abundant depleted uranium which we plan to de-convert and will provide those products and services more economically, with lower energy requirements, and at a higher purity standard than is currently possible."

"International Isotopes remains confident in our business plan and undeterred in our efforts.  Our progress continues unabated on our licensing, permitting, and design activities.  We believe that nuclear power will continue to play an important role in power production.  Even a fraction of the current uranium demands to supply existing reactors will produce an abundance of depleted uranium for de-conversion that would otherwise have to be stockpiled.  We remain committed to continuing to build a unique company to address the needs of the industry.  As the only planned 'green' environmentally friendly option for commercial depleted uranium in the United States we are optimistic about our future business."
