STOCKHOLM--(BUSINESS WIRE)--Aug 25, 2026--
Blykalla, a global leader in advanced nuclear technology, today submitted its application to the Swedish government for a second commercial advanced nuclear reactor park. The proposed facility, located at Untra in Tierp municipality (Uppsala county), would feature up to eight lead-cooled advanced modular reactors (AMRs) with a combined electrical capacity of up to 440 megawatts (MW). This follows Blykalla's first application submitted in May 2026 for a facility in Norrsundet, Gävle municipality.

"We continue to identify locations across Sweden where advanced nuclear power will deliver the greatest value," says Jacob Stedman, CEO of Blykalla. "Our reactors make it possible to build nuclear power where and when it’s needed – closer to industry, in new municipalities and inland locations where traditional nuclear power has historically not been possible."
Why Tierp
Using a thorough site selection process that analyzes multiple criteria, Blykalla has selected Untra as an ideal location. Untra met the company's key criteria: a strategic position in bidding zone SE3, where Sweden's electricity consumption is highest; proximity to existing hydropower at Untra and Söderfors, enabling a power cluster where dispatchable nuclear and regulated hydropower complement each other; and access to Svenska kraftnät's new 400 kV transmission infrastructure being built through Tierp municipality as part of the Uppsalapaketet program. The site also offers access to nuclear expertise from Uppsala, Gävle, and Forsmark.
New capacity in the region will support industrial development, long-term tax revenues, and enable future energy-intensive establishments.
The Swedish Nuclear Landscape
Sweden's Riksdag has established an ambitious energy target of 300 TWh electricity production by 2045, nearly double today's output. The government's plan calls for 2,500 MW of new nuclear capacity by 2035 and 10,000 MW by 2045. Blykalla's Tierp facility alone would contribute approximately 18 percent of the 2035 target.
The application follows a new Swedish regulatory framework adopted by the government and parliament in 2026, which enables the review and approval of new nuclear facilities. Government approval represents the first step in a multi-year process involving further review by the Swedish Radiation Safety Authority (SSM), the Land and Environmental Court, and Tierp municipality.
U.S. Expansion Continues
Blykalla's international expansion is accelerating in parallel with its Swedish development. The company has offices in both Sweden and the United States and is planning its first nuclear demonstration reactor in the U.S. This will provide critical technology validation before commercial deployment in Sweden. Blykalla also partners with U.S. companies including Oklo, contributing technical analyses to Oklo's DOE-authorized reactor pilot.
Advanced Modular Reactor Technology
Blykalla's Swedish Advanced Lead Reactor (SEALER) is a small modular reactor built on fourth-generation nuclear technology. Cooled by liquid lead – a coolant technology in use in nuclear applications since the 1960s – SEALERs offer inherent passive safety: cooling continues even during total power loss, without pumps, external electricity, or human intervention. Blykalla's patented Swedish aluminum-alloyed steels solve the corrosion challenges that previously prevented commercial deployment of lead-cooled reactors.
The SEALER is designed for factory serial production and easy transport, enabling faster deployment, lower cost per unit, and siting flexibility that traditional large-scale nuclear cannot achieve. Each unit produces approximately 55 MWe from a compact footprint suitable for locations previously accessible for nuclear power.
Blykalla is targeting first operations at Tierp during the first half of the 2030s, contingent on approvals from the government, regulatory agencies, courts, and Tierp municipality.
About Blykalla
Blykalla is a global leader in advanced nuclear technology, commercializing the next generation of clean, reliable energy through its lead-cooled reactor, the SEALER. Founded in 2013, the company has approximately 140 employees with offices in Sweden and the United States. Blykalla is building the Swedish value chain with partners including ABB, Höganäs, Kanthal, ESAB, and Alleima, and is constructing an electric test facility in Oskarshamn in partnership with Uniper.

NEW YORK (AP) — Carlos Alcaraz and Jannik Sinner made last year's U.S. Open feel like two weeks of killing time until the inevitable.
They had separated themselves from everyone else in men's tennis while meeting in the French Open and Wimbledon finals. It seemed a foregone conclusion they would make it three in a row, which is exactly what happened.
With the No. 1-ranked Sinner sidelined, Alcaraz only returning now to defend his title after missing four months and Novak Djokovic perhaps finally showing his age, the U.S. Open once again feels, well, open.
Just don't confuse that with meaning easier.
“It’s the same conversation,” American player Frances Tiafoe said. “Still got to beat seven guys however way you slice it.”
The women's side has its own questions, with two-time defending U.S. Open champion Aryna Sabalenka losing in the fourth round at Wimbledon and both hard-court tournaments she played since, putting her hold on the No. 1 ranking in jeopardy.
The top spot in the rankings could be in reach for multiple women and so is the trophy at the final major tournament of the year, with No. 3 Jessica Pegula saying “there’s not one or two super dominant players where you feel like they have to lose in order for you to have a chance.”
“It seems to me like maybe more open in a way, just because, I don’t know, there’s more chances,” added Pegula, who lost to Sabalenka in the 2024 final and last year's semifinals.
Play begins Sunday, with Pegula in Arthur Ashe Stadium's opening match and Djokovic leading off the night session before Venus Williams, at 46, faces Sofia Kenin.
Alcaraz gets one more day to prepare. He has been sidelined since April with a right wrist injury, deciding last week he was ready to return at the tournament where he has won two of his seven Grand Slam titles.
The most recent was at the Australian Open, but he went out not long after. Alexander Zverev won the French Open for his first major title, lost to Sinner in the Wimbledon final, then became the No. 1 seed in Flushing Meadows when Sinner determined the knee injury that has kept him out since that victory wasn't fully healed.
“It’s been a couple of months now where it’s been pretty similar: a lot of uncertainty, some of the top players, they’re kind of injured or they’re not playing. This is a little bit of the same, so we have seen lot of different players stepping up and a lot of different opportunities being up for grabs," said Alex de Minaur, the No. 6 seed from Australia.
Daniil Medvedev, the 2021 U.S. Open champion, pointed at players such as Zverev and Arthur Fils, who beat Tiafoe for the Cincinnati Open title before coming to New York, as players who know there's an opportunity they don't want to waste.
“For them, they’re probably thinking about it, not in a bad way, but they’re like, we have a better chance without Jannik and maybe Carlos not 100% yet,” the No. 7-seeded Medvedev said.
Djokovic exited the Cincinnati tournament in his first match and afterward mentioned an unspecified health problem that bothers him in the heat. That could make it difficult for the 24-time Grand Slam singles champion to make another lengthy run in New York at 39.
American men are still trying to end a Grand Slam drought that dates to Andy Roddick at the 2003 U.S. Open. Ben Shelton won in Montreal before Tiafoe's runner-up finish in Cincinnati, and Taylor Fritz lost to Sinner in the 2024 final in New York.
“I would say this is a golden opportunity,” ESPN commentator Patrick McEnroe said. “Obviously if Alcaraz comes back and gets through a few matches, looks good, he’ll quickly become the favorite. I mean, he’s the favorite right now, but he’d quickly become a bigger favorite. There’s no doubt the fact he hasn’t played since the spring, with Sinner out, this is a monster opportunity.”
Elena Rybakina, who beat Sabalenka in the Australian Open final, Pegula and No. 4 Coco Gauff are all in pursuit of the No. 1 ranking. Sabalenka could, depending on other results, lose it even if she becomes the first player to win three straight U.S. Open titles since Serena Williams from 2012-14.
“I’ll try to do my very best, and we’ll see what happens with the end of this tournament,” Sabalenka said.
She may be vulnerable, but Alcaraz perhaps even more so. In 2025, it seemed only one man could beat him. This time, the list could be lengthy.
“I mean, he’s always a guy we’re going to look at, but a lot of guys believe they can not only get him but win the event,” Tiafoe said. “It’s going to be an exciting U.S. Open.”
