They missed lot of things. Got some others wrong.
The first thing I noticed was them stating that is the turbine and point to the generator rotor saying that has the blades on it. Wow that was fancy cover for the rotor, we used to just put some heavy clear plastic over it, and then put a few work lights on the ground under it to drive off moisture. Noticed the humidity sensor note on the cover.
When they got up a level and then looked down at full turbine body, right next to them on the ground were a few diaphragms, as they are called. The fixed blades/vanes between stages in the turbine.
Never saw and good sized valves, they one they pointed out was not that big for a power plant and was manual operated. Let's see the turbine control valves and the hydraulics that power them. How about the feed lines, that would have been impressive.
I wanted to yell at the screen when they saw on the wall some layout/diagrams of the plant. Take a good hi-res picture of those, study them and come back now that you have a map of the place.
And yea the small disk packs, kids these days.
