At issue is some 25 million kilograms of uranium hexafluoride –so called high assay uranium tailings – that was incompletely processed at US government enrichment plants during the price slump. The enrichment plants separate uranium-235, a rare type that splits easily in bombs and reactors, and uranium-238, which does not.
During the uranium price drop, Washington decided to save money by skimming off only the uranium 235, which is easier to obtain during processing, sources at the US Department of Energy (DOE) told Bellona Web Tuesday.
“In the old days, they left a lot of good stuff behind,” said Julian Steyn, a uranium expert at Energy Resources International, a consulting firm in Washington in remarks reported by the New York Times. He could not be reached for further comment.
Uranium feeding frenzy
Frenzied lobbying from the US to Europe has broken out over who should receive the treasure chest of uranium-235, which is slated to become reactor fuel after it is run through an enrichment plant.
The estimated market value of the uranium in question is some $700 to $3 billion, DOE officials said – yet one of the most vociferous companies vying for this mother load – the United States Enrichment Corporation, or USEC - says it should essentially get the surplus for without paying anything. In return, said USEC, the United States will get boosted technology at its single enrichment plant and increased energy security.
But USEC is facing tough opposition on Capitol Hill, where many representatives say that giving the uranium to the company would be rewarding it for fiscal mismanagement.
Last Thursday, several senior members of Congress, led by Michigan Democratic Representative John Dingell, who is chairman of the House Energy and Commerce Committee - asked the Government Accountability Office to evaluate the options.
USEC’s Elizabeth Stuckle said that the company “denies allegations [of financial mismanagement]” and said that USEC obtaining the high-end assay tailings – some of which contain an enrichment of 50 percent or higher - would be a financial and technological advantage to both the company and the DOE.
In its current form, the material is not attractive to the makers of illicit bombs, because the technology to sort the two types of uranium is cumbersome and found in just a handful of plants around the world, DOE representatives told Bellona Web.
USEC and the HEU-LEU agreement
USEC was formed in the 1990s to privatize the enrichment monopoly that the government had run since the days of the Manhattan Project. USEC is also the US government’s agent in a key post-Cold War Soviet nuclear disarmament project called the HEU-LEU, or “Megatons to Megawatts” programme.
Under this 1995 agreement, the United States annually buys several hundred tons of Russian highly enriched uranium (HEU) and down-blends it to low enriched uranium (LEU) fit for use in commercial reactors.
The HEU-LEU agreement, which is scheduled to run through 2013, stipulates that the US buy 500 tons of HEU from Russia for a total of $7.5 m. USEC is currently purchasing the uranium at the rate of 30 tons annually for an average price of about $440 m, and shipping back both the enrichment and uranium components, according to USEC representatives.
Uranium could provide ‘value’ to DOE and upgrades to USEC
Stuckle said whether the high assay uranium tailings were obtained by USEC or not would have little impact on the HEU-LEU agreement. But according to a senior Senate aide, who spoke with Bellona Web on the condition of anonymity Tuesday, the uranium gift could make or break USEC.
The aide who has been briefed on the discussions said that the company’s future was uncertain and that if it were sold and broken up, the government would effectively be subsidizing some other entity “which could have serious implications for the HEU-LEU programme, though it is hard to predict what [kind].”
But if the uranium windfall does come their way, USEC believes that it will provide modernisation of its World War II era enrichment facilities and royalties to the US government.
At the moment, the single enrichment facility operating in the United States is in Paducah, Kentucky, and was built by the old US Atomic Energy Commission. It is run by USEC.
