Prior state
Nuclear power remained dominated by large light-water reactors; industrial heat was still largely fossil-derived; fusion remained experimental.
Material change
A modest fleet of factory-built modular fission reactors and a smaller number of commercial fusion pilot plants entered continuous operation, primarily serving industrial process heat and firm power niches.
Why now
The combination of first commercial fusion demonstration plants reaching sustained operation, modular-fission cost reductions, and industrial demand for high-temperature heat free of residual carbon pricing crossed the deployment threshold.
Mechanism and resistance
Resistance arose from renewable-industry interests, residual public safety concerns, and capital markets wary of first-of-a-kind risk. Counter-pressure came from heavy-industry users facing carbon costs and from states seeking energy security.
Consequences
Industrial heat emissions declined in covered sectors; nuclear capacity factors improved; public acceptance remained uneven.
End state
Advanced modular nuclear (fission and limited fusion) supplied a measurable fraction of industrial process heat and firm power in the named jurisdictions, no longer confined to demonstration status.
Observable test
Independent energy-balance statistics show advanced modular nuclear systems contributing more than 5 percent of industrial process-heat energy in at least two major industrial economies by the end of the decade.
Disconfirming sign
Continued exclusive reliance on fossil or resistive-electric industrial heat without material advanced-nuclear contribution.
