I have SOOO many questions, and this report answers SOOO few of them.

Like what is a reactor cavity? HN title makes it sound like they fell into the reactor but maybe this is some sort of moat or something? what did they fall into and why?

Almost certainly a refueling outage, this video will give you a good image of it

Does anyone have a sense for how significant of a dose of radiation this person got?

If it was just swimming in it that would be one thing. Ingesting the water could be very bad, depending on what's in it.

They keep the water in an LWR pretty clean to avoid corrosion problems. Thing is the slightest almost of tritium in the water will light up a portal detector like a pinball machine on tilt.

My question is what happened between when they went in the water and when they got off-site medical treatment. 7 hours seems like a long time. Is there on-site medical that would be doing something during that time?

Realistically, there is little to do besides decontamination which I'm sure they're equipped to do on site.

It doesn't say worker, just "person." I could understand falling in with some freak accident where you trip. But they ingested the water?!

Knowing nothing about nuclear reactor design, why would there ever be a dangerous pool that people could walk by that wasn’t covered? Hard to believe it’s like some kind of Bond villain complex with open pools everywhere. This must have been in the course of some kind of servicing that required opening something that normally stays closed?

Because it's generally speaking, not that dangerous. Water is very good at blocking radiation. That's part of the reason why the pool is filled with it to begin with.

> Non Emergency I guess in a nuclear reactor there is a lingual shift and the word emergency cant be used for just any old 911 call. Like how Australians apparently call a jellyfish bite "uncomfortable"

Aussie surfer here, the stings typically are uncomfortable. Some of the deadlier ones can be close to painless and only result in itching and result in you dying from respiratory failure 24 hours later. Others are downright painful with even strong opiate based pain killers struggling to cut through the pain.
