I can guarantee you there will be a proper investigation and steps taken to avoid this in the future. The non-emergency classification here applies solely to the notification that the contamination was transported off-site. Not to the fact that the incident occurred. Every accidental incident that occurs within the controlled area of a nuclear facility is investigated and evaluated for necessary policy changes.

And the reason the contamination transport off-site was classified as non-emergency was because even though the amount of radiation detected on the guy is less than he'd have gotten from flying in an airplane; nuclear safety standards are so unbelievably rigorous and strict that even that small of an incident needs to be reported; even if it presents absolutely no danger to anyone anywhere (not even the guy that was contaminated) and hence is classified as a non-emergency notification.

FTA: “This is an eight-hour notification, non-emergency, for the transportation of a contaminated person offsite“

⇒ the “non-emergency” classification isn’t about the “fell into a nuclear reactor pool”, but about sending the victim off site.

They returned to work the next day with minor injuries due to the fall. It doesn't sound like it was an emergency to me.
