Nuke plants, st tFA points out, are massive generators of paper. A lot of times spent reviewing past documentation for relevance, trends, etc. That is actually an area where Ai can be useful, especially since you are working with a narrow and reasonable well defined data set and requirements. Tailoring the LLM to taht can save a lot of time for an analyst/engineer/operator by identifying and collecting teh information needed for analysis and reporting. It's not like they're giving it access to the reactor control system and telling it to pull rods or increase steam flow, per TFA.
