Small modular reactors in service
Projection
Factory-built reactors arrive by truck and slot into old coal sites and data-centre campuses.
Small modular reactors shrink fission plants to a few hundred megawatts or less so they can be mass-produced. Fleets of them would give firm low-carbon power without decade-long megaprojects.
Why it’s plausible: Several designs are licensed or under construction; the dependency is whether serial factory production actually lowers costs, which only a sustained order book can show.
