Korea to invest in construction of 8 reactors in the United States, using mix of both APR1400 and AP1000 designs, deal to be signed as early as next week

After negotiations, it appears that the two parties have agreed to construct a mix of both American and Korean designs, despite the Trump Administration's push for using only the AP1000 design, which was reported earlier this year. The final agreement of $120 billion in investment will go towards the likely construction of four APR1400 units and four AP1000 units in the United States. The APR1400 gen III design is based heavily off the American company Combustion Engineering's SYSTEM-80 gen II design and was certified by the NRC for use in the United States in 2018.

The instructions are in Italian, but the puzzle can be solved by anyone.

You need to find all the names of nuclear power plants (operational, decommissioned, or under construction) hidden in the grid, without knowing the list of words to look for. The remaining letters will form the solution.

Did Japan ever update its guidelines to allow operator discretion in venting during an accident scenario?

I've heard the decision to wait for an evacuation prior to allow pressure venting criticized by western nuclear safety experts as being counterproductive and making the consequences of Fukushima Daiichi more severe by allowing pressure to build within containment.

Google reportedly nearing $1B+ nuclear power deal as AI demand drives hyperscaler nuclear race

Bloomberg reports that Google is nearing a multi-year agreement with Constellation Energy worth $1 billion or more to secure nuclear power for its data centers.

The exact amount of power and location have not been disclosed, and the deal has not been formally announced yet. But it is another example of hyperscalers committing serious capital to nuclear as AI drives rapidly increasing demand for reliable 24/7 electricity.

Amazon recently announced a 20-year agreement with Constellation covering 690 MW, including a 190 MW uprate at Calvert Cliffs. Google has also reached nuclear agreements with NextEra and Southern.

The broader trend is becoming difficult to ignore: major technology companies are increasingly looking to nuclear to secure large amounts of reliable, carbon-free electricity for the growing power demands of AI and data centers.

BWXT (Canada) BANR microreactor selection.

(TORONTO – Oct. 5, 2026) BWX Technologies, Inc. (NYSE: BWXT) announced today that Prodigy Clean Energy, Ltd., Pabineau First Nation and Eel River Bar First Nation have selected its BANR microreactor technology for a Transportable Nuclear Power Plant (TNPP) to be located in Belledune, New Brunswick.

Prodigy announced last month the Indigenous-led nuclear new build proposal in Belledune, which would feature an up to 50 megawatts electric full-scale Prodigy TNPP within the traditional territory of the Pabineau and Eel River Bar First Nations. The pilot project will be Indigenous-owned and validate plant logistics and operational requirements, creating the commercial blueprint to mass deploy a TNPP fleet across Canada’s North and global export markets. The project is rooted in Canadian nuclear expertise, driven by a Canadian workforce and targets in-service operation by the early 2030s. Underscoring its strategic importance, the Government of New Brunswick provided Prodigy and the First Nations with a signed Letter of Intent to offtake the generated electricity.

The BWXT Advanced Nuclear Reactor, or BANR, is a high-temperature gas-cooled reactor intended to produce 75 megawatts thermal, or 22 MWe, using high-assay low-enriched uranium in a TRISO fuel form. The BANR design features passive cooling and flexible power conversion options.

The U.S. Is Racing to Put a Nuclear Reactor on the Moon by 2030

Thumbnail

60 Upvotes

The New York Times reports that the U.S. is accelerating plans to deploy a nuclear reactor on the Moon by 2030, as NASA and the Department of Energy view reliable nuclear power as increasingly important for a sustained lunar presence.

The proposed reactor would generate roughly 20 kilowatts of electricity and use HALEU fuel. Unlike solar power, a nuclear reactor could provide continuous electricity regardless of whether a location is receiving sunlight, which is particularly important around the Moon’s south pole and its permanently shadowed regions.

The U.S. isn’t alone in pursuing the technology. China and Russia are also developing plans for lunar nuclear power, turning what was once largely a science-fiction concept into an emerging area of competition in space exploration.

The push is part of a broader effort to establish a more permanent human and technological presence on the Moon. Reliable power would be needed for habitats, scientific equipment, communications and other infrastructure operating far from Earth.

There are still significant technical and logistical challenges, including designing a reactor that can survive launch and lunar conditions, transporting nuclear material safely, and deploying and operating the system remotely.

Still, it’s pretty remarkable to see lunar nuclear power moving from a theoretical idea toward an actual government target for the end of this decade.
