U.S. Ramps Up Hunt for Uranium to End Reliance on Russia

by

More than 1,400 feet below an Arizona pine forest, miners are blasting tunnels in search of a radioactive element that can be used to make electricity.Two states north, in central Wyoming, drillers have been digging well after well in the desert, where that element — uranium — is buried in layers of sandstone.Uranium mines are ramping up across the West, spurred by rising demand for electricity and federal efforts to cut Russia out of the supply chain for U.S. nuclear fuel.Those twin pressures have helped lift uranium prices to their highest levels in more than 15 years, according to the consulting firm TradeTech, helping to resuscitate mining regions that entered a steep decline toward the end of the Cold War.Pinyon Plain miners working hundreds of feet beneath Kaibab National Forest.Uranium ore held by Matthew Germansen, an assistant mine superintendent at Pinyon Plain.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    At COP28, More Than 20 Nations Pledge to Triple Nuclear Capacity

    by

    The group, including Britain, France and the United States, said the agreement was critical to meeting nations’ climate commitments.The United States and 21 other countries pledged on Saturday at the United Nations climate summit in Dubai to triple nuclear energy capacity by 2050, saying the revival of nuclear power was critical for cutting carbon emissions to near zero in the coming decades.Proponents of nuclear energy, which supplies 18 percent of electricity in the United States, say it is a clean, safe and reliable complement to wind and solar energy. But a significant hurdle is funding.Last month, a developer of small nuclear reactors in Idaho said it was canceling a project that had been expected to be part of a new wave of power plants. The cost of building the reactors had risen to $9.3 billion from $5.3 billion because of increasing interest rates and inflation.Britain, Canada, France, Ghana, South Korea, Sweden and the United Arab Emirates were among the 22 countries that signed the declaration to triple capacity from 2020 levels.Tripling nuclear energy capacity by 2050, which would also help Europe reduce its dependence on Russia oil and gas, would require significant investment. In advanced economies, which have nearly 70 percent of global nuclear capacity, investments has stalled as construction costs have soared, projects have run over budget and faced delays. On top of cost, another hurdle to expanding nuclear capacity is that plants are slower to build than many other forms of power.Addressing the issue of financing, John Kerry, President Biden’s climate envoy, said that there were “trillions of dollars” available that could be used for investment in nuclear. “We are not making the argument to anybody that this is absolutely going to be the sweeping alternative to every other energy source — no, that’s not what brings us here,” he said. But, he added, the science has shown that “you can’t get to net-zero 2050 without some nuclear.”Nuclear power does not emit carbon, and an International Energy Agency report last year that said nuclear was crucial to helping to reduce carbon emissions in line with the Paris Agreement goals outlined in 2015. President Emmanuel Macron of France said nuclear energy, including small modular reactors, was an “indispensable solution” to efforts to curb climate change. France, Europe’s biggest producer of nuclear power, gets about 70 percent of its own electricity from nuclear stations.Mr. Macron and other leaders, including Prime Minister Ulf Kristersson of Sweden, called on the World Bank and international financial institutions to help finance nuclear projects. Mr. Kristersson said that governments must “assume a role in sharing the financial risks to strengthen the conditions and provide additional incentives for investments in nuclear energy.”While world leaders on Saturday called nuclear the most effective alternative to fossil fuels, some climate activists said nuclear energy was not a panacea.David Tong, a researcher at Oil Change International, said the pledge was divorced from the reality of nuclear energy — that it was too costly and too slow. “It’s a self-serving political pledge that doesn’t reflect the role that nuclear is likely to play in the energy transition, which is menial,” he said. “There is very small growth in nuclear — certainly nothing like tripling.” He said he rejected the stance that there was no pathway to limit global warming to 1.5 degrees Celsius above preindustrial levels, a goal set in the Paris Agreement to avoid the worst effects of global warming, without nuclear. Masayoshi Iyoda, an activist from Japan with 350.org, an international climate action campaign, cited the nuclear disaster at Fukushima in 2011 and said that nuclear power was a dangerous distraction from decarbonization goals. “It is simply too costly, too risky, too undemocratic, and too time-consuming,” he said in a statement.“We already have cheaper, safer, democratic, and faster solutions to the climate crisis, and they are renewable energy and energy efficiency,” Mr. Iyoda said.All but four of the 31 reactors that have begun construction since 2017 were designed by Russia or China, with China poised to become the leading nuclear power producer by 2030, the International Energy Agency said. This year, Germany shut its last three nuclear plants.Nuclear capacity rose in the 1980s, particularly in Europe and North America, but dropped sharply over the subsequent years after accidents at Three Mile Island in Pennsylvania in 1979 and Chernobyl in 1986. New technology and tighter regulations have been put in place since then. Americans are conflicted about nuclear power, but a growing number favor expansion compared with a few years ago, according to a Pew Research Center study published in August. More

    Why Russia Has Such a Strong Grip on Europe’s Nuclear Power

    by

    New energy sources to replace oil and natural gas have been easier to find than kicking the dependency on Rosatom, the state-owned nuclear superstore.The pinched cylinders of Russian-built nuclear power plants that dot Europe’s landscape are visible reminders of the crucial role that Russia still plays in the continent’s energy supply.Europe moved with startling speed to wean itself off Russian oil and natural gas in the wake of war in Ukraine. But breaking the longstanding dependency on Russia’s vast nuclear industry is a much more complicated undertaking.Russia, through its mammoth state-owned nuclear power company, Rosatom, dominates the global nuclear supply chain. It was Europe’s third-largest supplier of uranium in 2021, accounting for 20 percent of the total. With few ready alternatives, there has been scant support for sanctions against Rosatom — despite urging from the Ukrainian government in Kyiv.For countries with Russian-made reactors, reliance runs deep. In five European Union countries, every reactor — 18 in total — were built by Russia. In addition, two more are scheduled to start operating soon in Slovakia, and two are under construction in Hungary, cementing partnerships with Rosatom far into the future.For years, the operators of these nuclear power plants had little choice. Rosatom, through its subsidiary TVEL, was virtually the only producer of the fabricated fuel assemblies — the last step in the process of turning uranium into the nuclear fuel rods — that power the reactors.Even so, since the invasion of Ukraine in February 2022, some European countries have started to step away from Russia’s nuclear energy superstore.The Czech Republic’s energy company, CEZ, has signed contracts with Pennsylvania-based Westinghouse Electric Company and the French company Framatome to supply fuel assemblies for its plant in Temelin.Finland canceled a troubled project with Rosatom to build a nuclear reactor and hired Westinghouse to design, license and supply a new fuel type for its plant in Loviisa after its current contracts expire.“The purpose is to diversify the supply chain,” said Simon-Erik Ollus, an executive vice president at Fortum, a Finnish energy company.The Leningrad Nuclear Power Plant near St. Petersburg, Russia. Rosatom, a Russian company, dominates the global nuclear supply chain.Sezgin Pancar/Anadolu Agency via Getty ImagesBulgaria signed a new 10-year agreement with Westinghouse to provide fuel for its existing reactors. And last week, it moved ahead with plans for the American company to build new nuclear reactor units. Poland is about to construct its first nuclear power plant, which will feature three Westinghouse reactors.The State of the WarRussian Strikes: Moscow fired an array of weapons, including its newest hypersonic missiles, in its biggest aerial attack on Ukraine in weeks, knocking out power in multiple regions.Bakhmut: Even as Ukrainian and Russian leaders predicted that the fall of the city could open the way for a broader Russian offensive, the U.S. intelligence chief said that the Kremlin’s forces were too depleted to wage such a campaign.Nord Stream Pipelines: The sabotage in September of the pipelines has become one of the central mysteries of the war. A Times investigation offers new insight into who might have been behind it.Slovakia and even Hungary, Russia’s closest ally in the European Union, have also reached out to alternative fuel suppliers.“We see a lot of genuine movement,” said Tarik Choho, president of nuclear fuel unit at Westinghouse, adding that the Ukraine war accelerated Europe’s search for new suppliers. “Even Hungary wants to diversify.”William Freebairn, senior managing editor for nuclear energy at S&P Commodity Insights, said Russia’s march into Ukraine last year in some ways marked “a sea change.”“Within days of the invasion,” he said, “just about every country that operated a Russian reactor started looking for alternate supply.”In Ukraine, serious efforts to chip away at Russian nuclear dominance began in 2014 after President Vladimir V. Putin of Russia sent troops to occupy territory in Crimea and the eastern Donbas region. Ukraine, whose 15 Soviet-era reactors provided half the country’s electricity, signed a deal with Westinghouse to expand its fuel contract.It took roughly five years between the start of the design process and the final delivery of the first fuel assembly, according to the International Energy Agency.Ukraine “blazed a commercial trail,” Mr. Freebairn said. In June, Ukraine signed another contract with Westinghouse to eventually provide all its nuclear fuel. The company will also build nine power plants and establish an engineering center in the country.Technicians in a nuclear plant in Mochovce, Slovakia, last year. Slovakia is among the European countries seeking nuclear fuel suppliers other than Russia.Radovan Stoklasa/ReutersStill, a worldwide turn away from Russia’s nuclear industry would be a slog: The nuclear supply chain is exceptionally complex. Establishing a new one would be expensive and take years.At the same time, Rosatom has proved uniquely successful as both a business enterprise and a vehicle for Russian political influence. Much of its ascendancy is due to what experts have labeled a “one-stop nuclear shop” that can provide countries with an all-inclusive package: materials, training, support, maintenance, disposal of nuclear waste, decommissioning and, perhaps most important, financing on favorable terms.And with a life span of 20 to 40 years, deals to build nuclear reactors compel a long-term marriage.Russia’s tightest grip is on the market for nuclear fuel. It controls 38 percent of the world’s uranium conversion and 46 percent of the uranium enrichment capacity — essential steps in producing usable fuel.“That’s equal to all of OPEC put together in terms of market share and power,” said Paul Dabbar, a visiting fellow at the Center on Global Energy Policy at Columbia University, referring to the oil dominance of the Organization of the Petroleum Exporting Countries.As with oil and natural gas, the cost of nuclear fuel supplies has risen over the past year, putting more than $1 billion from exports into Russia’s treasury, according to a report from the Royal United Services Institute, a security research organization in London.The American nuclear power industry gets up to 20 percent of its enriched uranium from Russia, the maximum allowed by a recent nonproliferation treaty, according to the International Energy Association. France imports 15 percent. Framatome, which is owned by state-backed nuclear power operator, Électricité de France, or EDF, signed a cooperation agreement with Rosatom in December 2021, two months before Russia’s invasion, that is still in effect. Framatome declined to comment.The control room of a nuclear power plant in Paks, Hungary, in 2019. Two Rosatom nuclear plants are under construction in Hungary.Tamas Soki/EPA, via ShutterstockAnd even with the slate of new fuel agreements in Europe with non-Russian sources, deliveries won’t begin for at least a year, and in some cases several years.Around a quarter of the European Union’s electricity supply comes from nuclear power. With pending climate disaster prompting a worldwide push to decrease the overall use of fossil fuels, nuclear energy’s role in the future fuel mix is expected to increase.Still, analysts argue that even without formal sanctions, Russia’s position as a nuclear supplier has been permanently compromised.At the height of the debate in Germany last year over whether to keep its two remaining nuclear power plants online because of the war, their reliance on uranium enriched by Russia for the fuel rods emerged as one of the arguments against extending their lives. The last two reactors are to be shut down next month.And when Poland’s Council of Ministers approved the agreement in November for Westinghouse to build the country’s first nuclear power plant, the resolution cited “the need for permanent independence from energy supplies and energy carriers from Russia.”Mr. Choho at Westinghouse was confident about the company’s ability to compete with Rosatom in Europe, estimating that it eventually could capture 50 to 75 percent of that nuclear market. Westinghouse has also signed an agreement with the Spanish energy company Enusa to cooperate on fabricating fuel for Russian-made reactors.A nuclear power plant in Wattenbacherau, Germany, last year. The country’s last two reactors are to be shut down next month.Laetitia Vancon for The New York TimesBut outside the European Union and United States, in countries where support for Russia’s government has held up, Rosatom’s one-stop shopping and financing remain enticing. Russian-built reactors can be found in China, India and Iran as well as Armenia and Belarus. Construction has begun on Turkey’s first nuclear power plant, and Rosatom has a memorandum of understanding with 13 countries, according to the International Energy Association.As a new report in the journal Nature Energy concluded, while the war “will undermine Rosatom’s position in Europe and damage its reputation as a reliable supplier,” its global standing “may remain strong.”Melissa Eddy More

    Ukraine Energy Company C.E.O. Tries to Keep Lights On During War

    by

    Keeping millions of customers in Ukraine supplied with electric power amid the Russian invasion is, to say the least, challenging. Especially when the electrical grid itself becomes a target. “What we see now is that they attack transmission lines, substations, power generating stations,” said Maxim Timchenko, chief executive of DTEK, a large private Ukrainian energy company. In the early days of the war, he said, the Russian military seemed to be wary of wrecking critical civilian infrastructure.Now, he said, “they are not selective anymore.”In a video call from an undisclosed location in western Ukraine, Mr. Timchenko described how DTEK, which supplies about 20 percent of Ukraine’s electricity, and other Ukrainian utilities were scrambling to keep the lights on during the Russian onslaught.Amid the urgency, Ukraine, which is not a member of the European Union, has also managed to achieve something in a matter of weeks that it had worked on for years: a linkup to the power grids of neighboring E.U. countries, including, according to Mr. Timchenko, Romania, Slovakia, Poland and Hungary.“This will help Ukraine to keep their electricity system stable, homes warm and lights on during these dark times,” said Europe’s energy commissioner, Kadri Simson, in a statement. “In this area, Ukraine is now part of Europe,” she added.In case of a major hit to its power system, Ukraine could now apply for emergency electricity supplies from the European system, Mr. Timchenko said. Ukraine also severed its electricity links to Russia and Belarus just before the invasion to establish independence from power sources in hostile countries.When its transmission lines are damaged or severed, DTEK arranges for Ukrainian soldiers to escort its emergency repair crews, dressed in flak jackets, to reach affected sites. Mr. Timchenko said six of DTEK’s roughly 60,000 employees had been killed during the war, although not while performing duties for the company.The Russia-Ukraine War and the Global EconomyCard 1 of 6Rising concerns.
