Not a big deal, it's not super obvious if you're not nuclear or submarine trained.

Also, the fun part of fusion reactors is that they literally cannot melt down the way fission plants can. "Oh, no! the fuel injection system is running away!" "So vent the reaction chamber to atmosphere, it'll stop the reaction."

Research confirms importance of symmetry in pre-ignition fusion experiments

Researchers at Lawrence Livermore National Laboratory (LLNL) have retrospectively confirmed that implosion asymmetry was a major aspect of fusion experiments before achieving ignition for the first time at the Lab's National Ignition Facility (NIF), the world's most energetic laser.

Heating for fusion: Why toast plasma when you can microwave it

Some believe the future of fusion in the U.S. lies in compact, spherical fusion vessels. A smaller tokamak, it is thought, could offer a more economical fusion option. The trick is squeezing everything into a small space. New research suggests eliminating one major component used to heat the...

Or if you lose magnetic containment it vaporises the sides of the reactor chamber and the contaminants then stop the fusion process.

Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator

Inside the next generation of fusion vessels known as spherical tokamaks, scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) envisioned a hot region with flowing liquid metal that is reminiscent of a subterranean cave. Researchers say evaporating liquid...

Advanced materials could provide more durable metals for fusion power reactors

For many decades, nuclear fusion power has been viewed as the ultimate energy source. A fusion power plant could generate carbon-free energy at a scale needed to address climate change. And it could be fueled by deuterium recovered from an essentially endless source—seawater.

Bubbling, frothing and sloshing: Long-hypothesized plasma instabilities finally observed

Whether between galaxies or within doughnut-shaped fusion devices known as tokamaks, the electrically charged fourth state of matter known as plasma regularly encounters powerful magnetic fields, changing shape and sloshing in space. Now, a new measurement technique using protons, subatomic...

Nuclear fusion is fantastic but probably not in my lifetime unfortunately, I'll stick with playing jazz fusion keyboards for now.
