Finding Critical Path

The most reliable thing an industry tells you about its future is the size of the goal it is willing to say out loud. Nuclear just started speaking in fleets.

For most of the last forty years, a country that wanted nuclear announced a plant. One reactor, one site, one number, with the next decision deferred until that one was finished. The goal stayed small because the confidence behind it was cautious. This week the goal got bigger in three different capitals, and the size of the new number is what stops you. When the United States, Canada, and India each commit to ten reactors in the same stretch of days, the ambition stops being a forecast and becomes a plan, with money, policy, and steel already moving to back it. The signals this week show what that larger ambition is buying.

When one government raises its ambition, that is politics. When the same number turns up in the same week inside a loan office in Washington, on a forging floor in India, and within a fusion industry's own assessment of itself, the change is running deeper than any single policy. None of these actors takes its cue from the others. The largest commitment is the one with the most money behind it, so we start there.
