Europe’s first EPR, Unit 3 at Finland’s Olkiluoto nuclear power plant, was connected to the nation’s grid on March 12, Teollisuuden Voima Oyj (TVO), the facility’s owner and operator, has announced.

Olkiluoto-3 is also the first new Finnish reactor in four decades, and one of only three new reactors in Europe in the past 15 years. (Romania’s Cernavoda-2 began supplying electricity to the grid in August 2007, and Belarus’s Belarusian-1 in November 2020.)

Framatome announced on February 22 that the Nuclear Regulatory Commission has approved a license amendment that would allow Framatome’s shipping containers to transport, in the United States, fresh nuclear fuel assemblies containing uranium enriched up to 8 percent uranium-235.

Light water reactor fuel with higher enrichments and burnup capabilities than currently used under low-enriched uranium regulation could improve electricity generation and fuel utilization, possibly improving plant economics and providing more flexible reactor performance through extended operating cycles and more efficient core configurations.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

As we begin a new year, it is natural not only to look back (see page 24 for top news stories of 2021) but also to look forward. Nuclear News reached out to leaders in the nuclear community to get their predictions on what 2022 has in store, whether broadly or for their specific areas within the community. Although the responses below are wide-ranging and varied, one thing is made clear by all of the respondents: 2022 will see growth and opportunity. The future for nuclear is bright.

A longstanding issue in boiling water reactors—shadow corrosion on zirconium alloy fuel rods and fuel channels—has been reproduced in the Michigan Ion Beam Laboratory as part of an effort to understand and prevent the phenomenon. Research led by Peng Wang, a University of Michigan assistant research scientist in nuclear engineering and radiological sciences, was published in the January 2022 issue of the Journal of Nuclear Materials and described in a recent university news article.

The world faces an urgent need to decarbonize and expand clean energy systems. Earlier this year, the United States announced goals to achieve a 100 percent clean electricity grid by 2035 and net-zero emissions across the entire economy by 2050. Today, nuclear energy plants provide more than 50 percent of the United States’ carbon-free energy. Existing plants, along with the advanced technologies currently being developed and demonstrated, are crucial to the United States’ and the world’s clean energy future.

Technologies such as advanced non-light water reactors, which have higher operating temperatures than today’s light water reactors, will be vital to meeting economy-wide decarbonization goals. For example, process heat applications and chemical and synthetic fuel production require higher temperatures and currently rely on fossil fuels. Advanced reactors are the only carbon-free technologies that can provide the high temperatures these processes need.

NuScale Power has signed a memorandum of understanding with Prodigy Clean Energy and Kinectrics to explore and inform the development of a regulatory framework to address the licensing and deployment of a marine power station (MPS). The MPS would integrate one to 12 NuScale power modules into a marine-based nuclear power plant system. The MPS would be shipyard-fabricated and marine-transported to its deployment location, where it would be moored in place in sheltered and protected waters at the shoreline. Prodigy is Canada’s first commercial marine nuclear power developer, specializing in integrating existing power reactors into stationary-deployed marine power plant structures. Kinectrics provides life-cycle management services to the electricity industry.

The nuclear industry’s first 100 percent accident tolerant fuel assembly is in operation at Exelon Generation’s Calvert Cliffs plant, the Department of Energy announced yesterday. The advanced fuel will operate in the reactor for the next four to six years and will be routinely inspected to monitor its performance, the DOE said.

Located in Lusby, Md., Calvert Cliffs houses two pressurized water reactors. Unit 1 is rated at 907 Mwe, and Unit 2 at 881 Mwe.

French nuclear reactor company Framatome has completed its purchase of Rolls-Royce Civil Nuclear Instrumentation and Control. Framatome announced in December 2020 that it had agreed to acquire Rolls-Royce’s I&C business, which has operations in France, the Czech Republic, and China.

According to Framatome, the transaction builds on the company’s engineering expertise, enlarges its industrial footprint, and expands its global I&C systems development and deployment capabilities.

Here is a recap of industry happenings over the course of the past month:

Ukraine’s Energoatom signs deals for nuclear power exploration and deployment

Energoatom, the state-owned nuclear utility of Ukraine, and Westinghouse Electric Company have signed an agreement to bring Westinghouse AP1000 reactors to multiple sites in Ukraine. The signing took place at the U.S. Department of Energy headquarters in Washington, D.C., and was witnessed by Ukraine’s president Volodymyr Zelensky, U.S. energy secretary Jennifer Granholm, and Ukraine’s energy minister German Galushchenko.

In addition, Energoatom signed a memorandum of understanding with NuScale Power to explore small modular reactor deployment in Ukraine. Under the MOU, NuScale will support Energoatom’s examination of NuScale’s SMR technology, including a feasibility study for proposed project sites and the development of a project timeline and deliverables, cost studies, technical reviews, licensing and permitting activities, and project-specific engineering studies and design work.

The Hungarian office of Framatome this week signed a memorandum of understanding with Budapest-based research and economic development company Hunatom and the University of Dunaújváros to work together supporting nuclear education and training, research and development, and implementation of new technologies for Hungary and surrounding countries.

Representatives of the three organizations signed the MOU during a ceremony at Hungary’s University of Dunaújváros, about 40 miles south of Budapest.

The first of eight 160-ton steam generators for Unit 6 at Canada’s Bruce nuclear power plant was installed last week as part of the facility’s major component replacement project. “Congrats to the MCR team and our partners, including @AeconGroup, @Framatome_CA, @UEandC, @mammoetglobal, @BWXT, and others who contributed to this historic moment,” Bruce Power tweeted on September 30.

The component was fabricated at BWXT Canada’s Cambridge, Ontario, location and was shipped to the Bruce site in late 2020, as shown in this video.

The vendor responsible for generator removal is the Steam Generator Replacement Team (SGRT), a 50-50 joint venture between Aecon and the Steam Generating Team, itself a partnership between Framatome and United Engineers & Constructors. In July, Framatome announced that SGRT had been awarded an approximately C$350 million (about $278 million) contract by Bruce Power to replace the steam generators at Units 3 and 4.

Unit 1 at the Taishan nuclear power plant in China has been shut down to examine fuel rod damage and conduct maintenance, China General Nuclear Power Group (CGN) reported last Friday.

Bruce Power has removed the first of eight steam generators from Unit 6 at the Bruce nuclear plant in Ontario, the company announced earlier this week. The work was done as part of the facility’s major component replacement (MCR) project.

If Taishan-1 were operating in France, Électricité de France would shut down the reactor in order to assess the situation in progress and stop its development, according to a July 22 press release from EDF. The 1,660-MWe French-designed EPR—the recent subject of sensational press coverage of fuel rod failures—operates in China’s Guangdong Province.

The facts, once known, were uncomplicated. At Taishan-1 in China—the first Framatome EPR to be commissioned—operators detected an increase of fission product gases within the primary coolant circuit sometime after the reactor’s first refueling outage in October 2020. The cladding on a handful of the more than 60,000 fuel rods in the reactor had been breached, posing an operational issue—but not a public safety issue—for the plant.

Paving the way for increased automation in nuclear decontamination and decommissioning and waste management, French nuclear company Framatome announced that testing has confirmed the operation of its robotic systems for handling and sorting high-dose waste components.
