Why Russia Loves Germany’s Toxic Waste

Environmental groups have voiced concern in November 2019 that Russia is again accepting shipments of uranium tails, a byproduct formed when uranium is enriched, from a German nuclear fuel firm, reigniting a debate over whether the substance meets the definition of nuclear waste.  The shipments of the toxic compound – also called uranium hexafluoride – were halted in 2009 over revelations that Russia was accepting it from foreign customers and storing it in the open. At that time, Rosatom, Russia’s nuclear corporation, bowed to environmental pressure and promised to no longer import the radioactive substance.

But German government documents revealed in November 2019 by Greenpeace and the Russian environmental group Ecodefense show that the German-based enrichment company Urenco resumed the uranium tail shipments as long ago as May 2019.  According to Urenco’s contract with the Russian nuclear-fuel giant Teksnabeksport (Tenex), a subsidiary of Rosatom, some 12,000 tons of uranium tails are set to be delivered to Novouralsk, near Yekaterinburg by 2022. Four thousands tons have been sent so far….

Urenco, Germany

Uranium hexafluoride, also called depleted uranium, is a colorless radioactive powder that is produced as a byproduct of enriching uranium for use as fuel in nuclear power plants. Urenco, which is a partnership involving German, British and Dutch energy firms, has operated an enrichment facility in Gronau, Germany since 1985.  This facility stores depleted uranium in the open air. In the early 1990s, Russian opened its doors to reprocessing depleted uranium from foreign customers. A previous contract between Tenex and Urenco envisioned the import of 100,000 tons of uranium tails between 1996 and 2009.

The issue of whether uranium tails in fact constitute nuclear waste depends on whom you ask. Both Rosatom and Germany’s nuclear industry classify uranium hexafluoride as a recyclable material. The US Nuclear Regulatory Commission, however, has long held that uranium tails should be classified as nuclear waste – a view that Bellona, Ecodefense and Greenpeace share.  But while Rosatom asserts that uranium tails are valuable raw material, the motive for importing them is unclear. By most estimates, Russia already holds nearly 1 million tons of uranium tails from its own fuel production – making the need for another 12,000 tons from abroad questionable.

Uranium in Central Asia-Water Pollution

Kyrgyzstan:   Dr Osekeeva’s 38 years practising family medicine in this idyllic-looking valley in southern Kyrgyzstan make her a cataloguer of death. Cancer rates are rising, she says, and she thinks she knows the culprit. Buried along the river in and around Mailuu-Suu, a town of some 20,000 people, lurks the poisonous legacy of the Soviet Union’s first atom bombs: 2m cubic metres of radioactive waste leaching into the water supply.  Mailuu-Suu was once closed to outsiders. Its well-paid workers were treated as members of the elite: they received perks such as handouts of beer and beach vacations in Crimea. Over the years, they mined and milled 10,000 tonnes of uranium ore into yellowcake, ready for conversion into bomb material. Uranium was also sent from as far as East Germany and Czechoslovakia to be processed here.

With the collapse of the Soviet Union and local industry in 1991, the specialists left. Supervision of the town’s 23 tailings sites—dumps containing the hazardous leftovers—became sporadic. Fences and warning signs have been looted for scrap metal. Today, cows graze atop the invisible menace. Goats sleep inside an abandoned uranium mineshaft. Local dairy products and meat are often unsafe; kitchen taps spew silty river water laced with heavy metals.

Neighbouring countries worry. The river through Mailuu-Suu is prone to earthquakes and floods. It is only about 15 miles (25km) upstream from Central Asia’s breadbasket, the Fergana Valley, which is home to over 10m people. Every few years landslides block the flow, threatening to flood the dumps and wash radionuclides over the melon patches and cornfields downstream. A European aid official warns of a “creeping environmental disaster”.

Mailuu-Suu is only a small part of the picture. Dotting hills above the Fergana—straddling the post-Soviet republics of Kyrgyzstan, Tajikistan and Uzbekistan—lie dozens of other tailings dumps. Many also contain other heavy metals such as lead, arsenic and cadmium, which can be more dangerous to the body than radiation. Few are secured or monitored.

The three countries are hardly on speaking terms, so cross-border co-operation is non-existent. …Kyrgyzstan, however, has made a little progress. Between 2010 and 2012, an $8.4m World Bank-led project moved 150,000 cubic metres of waste from one of the most accident-prone tailings dumps in Mailuu-Suu to a safer spot up the hill. But locals complain they were not briefed properly about this. They say workers stirred up radioactive dust; many claim cancers have grown more frequent since the transfer.

The government is appealing to the European Union for $50m to deal with ten sites at Mailuu-Suu it says are in need of “urgent” relocation. Others estimate that even this relatively small project would cost hundreds of millions. Kyrgyz officials grumble that donors are slow to make decisions, spending millions on assessments that take years.

The International Atomic Energy Agency says the landslides and flooding make Mailuu-Suu “high risk” and a top priority. But donors can be forgiven for hesitating. Corruption and inertia have eroded many government institutions in Kyrgyzstan and its neighbours.
