On June 2, Energoatom signed a new agreement with the US-based Westinghouse Electric Company that will enable Ukraine’s nuclear power plants to get all their fuel from Sweden instead of Russia. Where is the Ukraine going to get its uranium to fuel this project? From Sweden? I don’t think so. It takes a lot of time and capital to build a nuclear power plant. And Chernobyl, how is it fairing? This is a highly speculative article … it is unlikely Ukraine could get enough Uranium to power Europe; and even if it did, nuclear power is the most expensive way of generating electricity … so this article is mostly talk without substance.

The folly of nuclear power
For nearly a month, IAEA Director General Rafael Mariano Grossi has been saying that an IAEA-led international mission to the Zaporizhzhia plant is urgently needed. Grossi has called the situation there “untenable” and warned that the occupation is delaying maintenance work, compromising the Ukrainian staff’s ability to make decisions, and increasing the risk of an accident or security breach.
Grossi initially said Ukraine had requested an expert mission, but Energoatom accused Grossi of “lying.” The Ukrainian operator said it did not want the IAEA to visit until Ukraine regained control of the site, because an official visit would legitimize the Russian occupation. Also, Energoatom questioned how a mission could safely reach the site.
Grossi has also expressed concerns about missiles flying close to another site, the South Ukraine Nuclear Power Plant. On June 5 and again on June 26, Energoatom reported that the plant’s surveillance cameras recorded video of a Russian cruise missile flying “critically low” over the plant. Ukraine previously reported a missile flying directly over the same site on April 16.
If a stray missile were to strike a reactor, containment structure, or fuel storage facility at one of Ukraine’s four operating nuclear power plants, it could lead to a nuclear accident.
Storing Ukraine’s spent fuel. Nuclear fuel remains highly radioactive long after it has been used to generate electricity. When spent fuel rod assemblies are first removed from a reactor core, they are stored in a pool. After a few years of submerged cooling, the rods can be moved into concrete dry casks that are air-cooled.
In the United States, that’s as far as the radioactive waste from commercial nuclear power plants has gone. But in Ukraine, Energoatom and Holtec International—a US-based company that makes casks, cranes, transporters, and other equipment for storing and transporting spent fuel—were putting the finishing touches on a Centralized Spent Fuel Storage Facility when the Russians invaded.
The new facility is an “interim” storage site where up to 458 casks filled with spent fuel from three of Ukraine’s four nuclear power plants—South Ukraine, Rivne, and Khmelnytsky—will be interred until a permanent underground repository can be created. (At the Zaporizhzhia plant, spent fuel will remain onsite in dry casks for the next 50 years.)
The storage facility, which is designed to last at least 100 years, is located about 14 kilometers from the Belarus border, within the Chernobyl Exclusion Zone. (Holtec wants to build a similar facility for consolidated interim storage of US nuclear waste in New Mexico.) Energoatom and Holtec have been collaborating on the storage facility since 2005, with construction beginning five years ago.
Last November, the two companies began preparing to transfer waste by conducting cold tests (without actual fuel) at the storage facility and the Rivne plant in northwestern Ukraine. A 43-kilometer spur built last year connects the storage facility to the nation’s rail system.
Energoatom expected to receive an operating license for the facility on March 5, and delivery of the first casks containing actual fuel in late April, but the Russian invasion delayed the license approval until April 25. The facility is now ready to start accepting spent fuel, but there’s another snag: a ban on transporting nuclear materials through Ukraine.
Any transport of radioactive waste carries some risks, but transporting nuclear material is especially risky in a war zone. Fuel-laden casks travel by train and could be struck by Russian missiles or artillery, intentionally or not. Storage casks do not have as much protection from high-velocity impacts as a reactor containment building.
In the past, Ukraine sent its spent fuel to Russia for reprocessing. One of the reasons for building the storage facility was so that Ukraine would no longer have to pay Russia’s state nuclear corporation Rosatom for expensive waste handling services. Energoatom hoped to save up to $200 million by operating its own facility.
New fuel supplier. Ukraine is also getting out of the business of buying nuclear fuel from Russia. On June 2, Energoatom signed a new agreement with the US-based Westinghouse Electric Company that will enable Ukraine’s nuclear power plants to get all their fuel from Sweden instead of Russia. (Earlier fuel contracts between Energoatom and Westinghouse, signed after Russia annexed Crimea in 2014, had already reduced Ukraine’s dependency on Russia.)
The fuel agreement was one of three agreements signed that day in the presence of Ukraine’s Minister of Energy, the Swedish Ambassador to Ukraine, the president of Energoatom, and the president of Westinghouse. A second agreement covers Energoatom’s intent to build nine new nuclear reactors designed by Westinghouse—which sells nuclear reactors as well as nuclear fuel—and the third agreement will create a Westinghouse Engineering and Technical Center in Ukraine.
Energoatom President Petro Kotin vowed that the company would “not only write a new chapter in the history of Ukraine’s nuclear energy but also make an important contribution to the energy independence of Europe.”
Energoatom had already planned to build five new Westinghouse AP1000 nuclear reactors—the same type of reactor currently under construction at the United States’ Vogtle nuclear plant in Georgia but plagued by delays and massive cost overruns. Two other AP1000 reactors that were under construction in South Carolina were terminated in 2017.
Energoatom plans to speed up construction of its first AP1000 by using reactor components that were built for the failed South Carolina project but not yet installed. The utility will also repurpose structures created for a Russian-designed reactor that was only 28 percent completed at Ukraine’s Khmelnytsky nuclear plant when construction halted in 1990.
To some experts, that looks like cutting corners. From Energoatom’s perspective, it’s the kind of ingenuity that has served Ukraine well in its war with Russia.
“Grossi initially said Ukraine had requested an expert mission, but Energoatom accused Grossi of “lying.” The Ukrainian operator said it did not want the IAEA to visit until Ukraine regained control of the site, because an official visit would legitimize the Russian occupation.
