    SILEX a threat?

    Since Usec, with backing from the DOE, continues to fund the ACP, they must not think that SILEX technology (which Usec used to own) is a strategic threat. That's either because SILEX may not be a slam-dunk success, or because the two technologies may be able to co-exist.

    What's needed from Usec is a clear statement of the case that SILEX is not a threat to ACP, and why. Even with continuing progress on ACP, SILEX will cast a shadow over the value of USU shares until management becomes more engaged in this argument.

    • If the person who insists on having my post removed and bury their head in the sand then go ahead.
      google some of this.
      The projected level of extra capacity (that would result under the
      circumstances described earlier in this paragraph) would provide a supply margin to assure the
      availability of enriched uranium for commercial nuclear power plants in the United States, given
      the uncertainties surrounding the construction and operation of the ACP and EREF facilities.

      In other words, the NRC staff concluded that the proposed GLE Facility is necessary to help assure that there is sufficient domestic enrichment capacity, especially in light of the uncertainties associated with the other domestic enrichment facilities, and that having the proposed GLE Facility licensed and in operation would provide an additional domestic source of enriched uranium consistent with national energy security objectives.

      The NRC staff also considered statements made by DOE and the National Nuclear Security Administration that indicated that having additional domestic sources of enriched uranium is important to U.S. national energy security.

      • However, USEC was not able to address DOE’s concerns regarding
        the financial and project execution to DOE’s satisfaction during 2011 (Ex. NRC054). Instead of

        moving forward with a conditional commitment for a loan guarantee, in the fall of 2011, DOE
        proposed a two-year cost-share research, development, and demonstration (RD&D) program to
        enhance the technical and financial readiness of the centrifuge technology for commercialization
        (Ex. NRC054). DOE indicated that USEC’s application for a DOE loan guarantee would remain
        pending during the RD&D program, but DOE has given USEC no assurance that a successful
        RD&D program will result in a loan guarantee (Ex. NRC054). USEC is working with DOE and
        Congress to secure DOE funding for the RD&D program (Ex. NRC054).

    • I would be a little concerned Sponge Bob, because the way they are talking the GLE plant at Wilmington is going ahead, that's if you consider that the DoE are talking to GE about a second plant at Paducah, if that is the second plant then surely there must be a first one?

      The US Department of Energy (DoE) is in preliminary discussions with Global Laser Enrichment (GLE) about establishing a laser enrichment facility at the site of the Paducah gaseous diffusion plant in Kentucky.

      GE signed an exclusive commercialization and license agreement with Australia's Silex Systems for the SILEX (Separation of Isotopes by Laser Excitation) uranium enrichment technology in early 2006. GLE was issued with a construction and operation licence in September for a full-scale laser enrichment facility in Wilmington, North Carolina.

      According to Silex Systems, the DoE has started talks with GE-Hitachi (GEH) subsidiary GLE to evaluate the possibility of building "another" laser enrichment plant at the Paducah site to enrich its stockpiles of high-assay depleted uranium tails. The DoE owns some 100,000 tonnes of such tails, which are stored at Paducah as well as at the shut down Portsmouth diffusion enrichment plant in Ohio.

      The DoE has been evaluating opportunities for the Paducah plant after May 2013, when operations at USEC's diffusion plant there are expected to end. These include the possibility of private companies operating the facility as a commercial uranium enrichment facility.

      • I'm not saying that ACP is dead, because it may not be? you need to read a PDF called :-Limiting Transfers of Enrichment and. Reprocessing Technology. (just google that line )

        Seems to me like the US is softening it's total objection to the sale of E & R technology to certain countries? maybe the US might allow the sale of some of the ACP tech to friendly countries, whilst keeping the more efficient Laser Enrichment and Reprocessing all to themselves, for the purpose of selling their services to countries that have signed agreement similar to what the UAE has done? where they get favorable treatment in Enriched Uranium purchases, under the agreement they will hand back their spent fuel for Reprocessing in the US?

        If the US has the cheapest source of Enriched Uranium then perhaps they could corner the market, but still allow the sale of certain technologies, the second best tech perhaps? just not their best and most efficient one?

        Maybe that is one way that the US and USEC could recover some if not all of their sunk costs and perhaps more? on their ACP technology?

        This sale of certain Enrichment and Reprocessing technology in the PDF certainly makes a mockery of any proliferation arguments of these technologies though, doesn't it?

    • This is the real issue

      Sentiment: Strong Buy

    • I believe it is a real threat Sponge Bob, for instance why would the DoE even consider using the laser enrichment process if it didn't work? or why would GE consider building a "SECOND" plant, surely that means that the first plant is a given?

      22 November 2012

      The US Department of Energy (DoE) is in preliminary discussions with Global Laser Enrichment (GLE) about establishing a laser enrichment facility at the site of the Paducah gaseous diffusion plant in Kentucky.

      GE signed an exclusive commercialization and license agreement with Australia's Silex Systems for the SILEX (Separation of Isotopes by Laser Excitation) uranium enrichment technology in early 2006. GLE was issued with a construction and operation licence in September for a full-scale laser enrichment facility in Wilmington, North Carolina.

      According to Silex Systems, the DoE has started talks with GE-Hitachi (GEH) subsidiary GLE to evaluate the possibility of building another laser enrichment plant at the Paducah site to enrich its stockpiles of high-assay depleted uranium tails. The DoE owns some 100,000 tonnes of such tails, which are stored at Paducah as well as at the shut down Portsmouth diffusion enrichment plant in Ohio.

      The DoE has been evaluating opportunities for the Paducah plant after May 2013, when operations at USEC's diffusion plant there are expected to end. These include the possibility of private companies operating the facility as a commercial uranium enrichment facility.

      Silex Systems noted, "Access to existing infrastructure at Paducah could realise significant cost savings and reduce the overall time to establish a full-scale laser enrichment plant."

      The company said that discussions are currently at an early stage and the proposed plan "is dependent on further detailed analysis."

      Silex CEO Michael Goldsworthy commented, "Whilst the key event over the past year was the recent approval by the US Nuclear Regulatory Commission of the licence for the proposed commercial SILEX Laser Enrichment Plant in Wilmington, North Carolina, this is also a welcome development." However, he stressed, "This is a very early stage evaluation of the opportunity."

    • This threat really hit the real question about Usec. It should be the most popular on the board

      Sentiment: Strong Buy

    • Is silex a theat? Any opinion of you on the board is wel acepted

      Sentiment: Strong Sell

    • document created 28/4/2010

      Earlier this year, President Obama directed the Secretary of Energy to establish the Blue Ribbon Commission on America’s Nuclear Future to make recommendations for developing a safe, long-term solution to managing the Nation’s used nuclear fuel and nuclear waste. The highly respected members of the Commission have already started their work and will provide a final report to the President within the next two years. GEH has requested an opportunity to engage with the Commission to discuss the benefits of full-recycling and the establishment of recycling centers. Some of the benefits of recycling that we will outline include:
      • Reducing the required storage time of used nuclear fuel by over 99.99%, from greater than 1 million years to several hundred years;
      • Using the current U.S. inventory of 60,000 metric tons of used nuclear fuel to meet the electricity generation demands of the United States for over 100 years if recycled within a high energy GEN IV reactor (using 2008 U.S. electricity generation data); and
      • Using the U.S. inventory of depleted uranium that is discarded during the enrichment process that has the potential to meet the electricity generation demands of the United States for over 900 years if recycled within a sodium-cooled GEN IV reactor (using 2008 U.S. electricity generation data.

    • Right!! Why don't usec do this clear statement of the case that SILEX is not a threat to ACP?
