While nuclear fission derives energy from splitting atomic nuclei, nuclear fusion does so by joining them, releasing energy in the process. Though both atomic reactions produce energy by modifying ...

Private fusion companies building prototype reactors will face federal rules on tritium and neutron-activated waste but will ...

Standardizing calculations of the helium byproducts generated in advanced fission and fusion energy system materials can increase reactor safety and longevity, according to a study led by University ...

The nation's top regulatory body for nuclear power plants and other nuclear materials, the Nuclear Regulatory Commission, has officially voted to regulate nuclear fusion differently than fission. The ...

Last December physicists working on fusion claimed a breakthrough. A team at the National Ignition Facility (NIF) in California announced it had extracted more energy from a controlled nuclear fusion ...

Nobody said building a fusion power plant would be easy. Physicists and engineers have been working for decades to crack the problem. But over the last year or so, fusion startup Zap Energy took a ...

More than 110 countries and countless companies have pledged to reach net-zero emissions by 2050, but can they get there with existing technologies? Probably not. But the net-zero equation is complex.

A Seattle-area startup best known for chasing one of the hardest problems in physics has decided it cannot wait for fusion alone. Zap Energy announced in June 2026 that it will begin pursuing ...

Clean and sustainable nuclear energy may sound like a washed up, post-war dream, but the modern reality of this power source is much more complicated. For one, nuclear energy in the coming decades ...
