UN action maypave way for easier Uranium acquisition


April 18, 2019

NEW YORK: Diplomats at the UN and International Atomic Energy Agency (IAEA) have been reclassifying uranium as a “critical material.” That would allow countries to tap funding from the World Bank and other development institutions to ensure supply under the guise of the UN’s sustainable development goals. While the change could potentially cut mining waste, it might also lead to a reduction of the scrutiny uneconomical projects get from nuclear inspectors.

The biggest beneficiaries to the new rules would be countries including Jordan and Saudi Arabia, which have large reserves of phosphate and growing populations that need to be fed with the crops it fertilizes. However, the extraction process could weigh on the uranium market, where prices have stagnated since the last recession started in 2008, international media reported.

“The main use of phosphate is in fertilizer, but it can also contain a lot of uranium,” said Harikrishnan Tulsidas, a UN official and former IAEA mining adviser who was one of the proposal’s authors. By turning uranium into a byproduct of phosphate, the nuclear industry could blunt “boom-bust” mining cycles by linking uranium supply with other industries, like agriculture, he said.

Strong links between phosphate and uranium emerged as far back as the 1950s in the US, according to a Stockholm International Peace Research Institute report co-authored by Vitaly Fedchenko. America’s earliest nuclear arsenal used uranium derived from a fertilizer plant in Florida. Countries like Israel, India and Pakistan have also looked to phosphate as a way around import restrictions for atomic material, according to Kelley, who called the method “a sore on the non-proliferation landscape.”

To derive uranium, phosphate rocks are ground and milled at the plants before being fed into a chemical process yielding phosphoric acid. Another stage of chemical treatments yields a black uranium concentrate that can appear in powdery or sludge-like form, according to Kelley, who now advises governments from a Swedish security institute.

Though in its elemental form uranium can’t fuel a reactor or make a bomb – it first must be enriched or turned into plutonium -- it’s the fundamental ingredient for all nuclear programs. BHP Group Ltd.’s Olympic Dam is currently the world’s biggest uranium mine.

The kingdom is pursuing nuclear power but has also has warned it could seek weapons too. Saudi Arabia is unique among countries with the potential to extract uranium from phosphate: it’s flush with oil money to invest and has signaled an ambition to build a nuclear program.

The technology needs big financial backing. Commercial plants cost as much as $1.3 billion, according to Julian Hilton, who advocates for “green nuclear fuel sources” and helped draft the UN’s new guidelines.

“This is at the center of the food, energy and water triangle that’s the key to everything,” Hilton said in an interview. Phosphate extraction is a “win-win for everybody,” resulting in cleaner fertilizer, at reduced energy intensity, with uranium collected as a valuable byproduct, he said.

The risk that uranium is diverted for weapons could be reduced if countries adopted stricter international rules to safeguard uranium stockpiles. But implementing tougher rules, what the IAEA calls an additional protocol, aren’t required as a precondition to get aid in recovering uranium from phosphate, according to IAEA Director General Yukiya Amano.

That’s a concern among non-proliferation experts because of the IAEA’s checkered past with uranium. The agency helped Pakistan develop resources that likely went into that country’s weapons program. In Syria, under investigation since 2007 over clandestine nuclear work, the IAEA helped build a pilot extraction facility at a fertilizer plant in the city of Homs.

“Doing it with the IAEA and UN gives a kind of cover that allows countries to take one small step without raising suspicions,” said Scott Kemp, a physicist at the Massachusetts Institute of Technology, who advises the U.S. government on non-proliferation. “If this technology is used, it begs the question what will be done with the material?”

Based on current prices, it’s cheaper for countries that want nuclear power to buy uranium on the market than it is to invest in new exaction. Over the last decade, the market for reactor fuel has been battered by safety concerns, cheap natural gas and the shift toward decentralized electricity grids powered by renewables.

“Recovering uranium from phosphate is not economic at the moment,” said Nick Carter, a vice president at UX Consulting Co, which advises makers of nuclear fuel. Prices would have to rise three-fifths just to break even, he said.

Farm demand for uranium-free phosphate fertilizers is also slack, according to Alexis Maxwell, research director of Green Markets, a fertilizer research firm owned by Bloomberg LP. The Houston-based analyst said that adopting uranium extraction would “pose risks to fertilizer companies.”

With the UN set to issue its final uranium-resource guidelines later this year, the weapons-investigator Kelley said international monitors should pay attention to those market signals.

“Because this process isn’t economically competitive, the IAEA should be especially cautious when assisting countries to produce uranium.” Kelley said. “It means they’re acquiring uranium for other purposes than power and that should raise a flag.”
