FACT: More than 90% of the potential energy still remains in spent nuclear fuel.
Some advanced reactors under development could consume or even run on this fuel in the future.

🎉WE HAVE CRITICALITY! 🎉
On June 4, 2026, at around 12:30 MDT, Antares Nuclear’s Mark-0 microreactor achieved initial criticality at Idaho National Laboratory.
It is the first nuclear test reactor to go critical under the U.S. Department of Energy's Reactor Pilot Program. Data gathered from the test will help validate the nuclear fundamentals and instrumentation and control of the company’s advanced reactor design and provide a fast-tracked approach to future commercial licensing activities.
The demonstration was conducted in partnership with DOE and INL, with support from BWX Technologies, Inc. (BWXT) and the U.S. Department of War.
The Reactor Pilot Program was created in June 2025 to reform reactor testing at DOE in response to President Trump’s Executive Order 14301, which set a goal of achieving criticality for at least three test reactors using the DOE authorization process by July 4, 2026.
Congratulations to Antares on reaching this historic milestone!

The Big 45! 🎊
On this day back in 1981, Salem Unit 2 first connected to the grid.
The two-unit plant, along with its neighboring Hope Creek plant generate over 40% of New Jersey’s power.

WORTH ITS SALT 🧂: Oak Ridge National Laboratory's Molten Salt Reactor Experiment tested the potential use of liquid fuel reactor technologies for commercial power generation.
It opened on this day in 1965 and operated until 1969, logging more than 13,000 hours of valuable data that is still used today.
