What AI already does for nuclear power reactor operatorsWhat nuclear power reactor operators no longer do alone

O*NET lists 19 tasks for nuclear power reactor operators. None of them shows meaningful AI use at work yet.

What it does not touch, yetWhat still needs a human

19 of the 19 tasks show no AI use at work in the data.

What this does and does not mean

Exposure is observed use, not a forecast. Anthropic maps work conversations with Claude onto the tasks O*NET lists for each job and asks, of the tasks AI could speed up, which are actually being used for at work. A use that does the task outright counts in full and a use that assists a person counts half. The task scores are averaged into the occupation figure by the share of time spent on each task.

A high figure means AI is already part of how this work gets done. It does not mean anyone has been replaced. Anthropic's own reading of the labour market finds no systematic rise in unemployment among exposed workers so far, and about 14% fewer 22 to 25 year olds starting exposed jobs.No measurable rise in unemployment among exposed workers so far, and about 14% fewer 22 to 25 year olds starting these jobs.
