Whoa! "Nuclear SMR welding breakthrough: A year's work now takes a day"

To power all the AI.

From New Atlas, February 20:

Small Modular Reactor (SMR) construction shifts into high gear, as UK company Sheffield Forgemasters welds a full-size nuclear reactor vessel in under 24 hours instead of the usual 12 months. The rollout of this game-changing tech could be massive.

Modular reactors have the potential to revolutionize the nuclear power industry by turning nuclear generating plants from major civil engineering projects to factory-produced commodities. Instead of being essentially one-offs, modular reactors have a standardized design, can be mass produced, installed in any number required to serve local needs, and don't require the incredibly expensive buildings conventional reactors depend upon.

The problem is that there are bottlenecks in how to build reactors of any size. One is welding the vessels used to contain the reactor core, isolating it from the outer environment. Using conventional techniques, this can take over a year, but Sheffield Forgemasters have reduced this to under a day using what is called Local Electron-Beam Welding (LEBW) to complete four thick, nuclear-grade welds....

We may have to re-think the addition of butter to the model portfolio.
