The Developers: Restarts, SMRs, and the Field
The nuclear-for-data-centers field splits cleanly into two bets. One bet is that you restart or expand plants that already exist, because a license and a cooling system and a switchyard are worth more than any pitch deck. The other bet is that a new generation of small modular reactors will finally make nuclear something you manufacture rather than something you excavate. Both bets have real companies, real filings, and real customers behind them now, which is what separates this cycle from the last three false dawns. I am not going to tell you which developer wins. I am going to tell you what each one is actually promising, and what has to be true for that promise to hold.

What is the core difference between the restart strategy and the small modular reactor strategy for serving data-center load?
Show the answer
The restart strategy brings existing, already-licensed reactors back into service or expands them, offering the fastest path to firm power. The SMR strategy builds new, smaller, factory-produced reactors designed to lower the cost and schedule risk of nuclear, but it must still clear first-of-a-kind licensing and construction before delivering power.
