Reply to Why were the control rods in the reactor featured in the HBO series 'Chernobyl' (2019) tipped with graphite? by Figorama
Off topic, as someone who operates kia nuclear power plant, the Chernobyl incident absolutely infuriates me every time I hear about it. The RBMK is just..... wrong. It's bass ackwards, and completely dangerous (obviously)
That said, Chernobyl is a great show. "Go on, tell your lie"

Yes it leaves a lot to be desired, because well, there is. The entire process would take me the rest of the month to specifically explain. If someone is interested in all of that, the info is out there

Basically, yes. With the result of the preheated feedwater going to the water walls, to the economizer, to the superheater to the..... Honestly I could go on for a while here as you seem to also know lol

In power plants, water is under pressure. Increasing the pressure, also increases the boiling point. The water at my plant is around 800 degrees Fahrenheit, yet still a liquid. We do this through a series of enclosed heaters, which actually increases pressure as steam is released, which in turn makes the steam condense back to water at a higher temperature. Our plant does this 3 times. Which then the water goes into the boiler. This process is called superheating. Or known as "superheated steam."
Our throttle pressure is 3500psi. So you can imagine just how hot our water can get before it turns into steam (there's a chart out there if you're curious about pressure and temperature of liquid and steam.) Now let's add that water expands about 1600 times from liquid to steam. The result, is a massive amount of energy.
Edit- I appreciate the feedback, and yes, there are many different processes that are going on, in order to generate power, and the boiler process. I'm trying to simplify, because to explain the entire process I'd need about 50 more pages, as it seems many here also know.

They are basically giant hot tubs. Cooling water can be pretty much anything. In most cases, it's river water. The water goes into the intake, where there are basically just screens to catch any debris and even fish. This water goes into the tubes of the condenser. The steam from the turbine, hits these cooling tubes, and condenses the steam back into boiler water. The boiler water then goes into the "hotwell," which is then returned right back into the boiler to make steam. Rinse and repeat.
The cooling water though, is now super hot. This water is sent out to the cooling towers. At a nuclear plant, those are those big ass signature towers. At a coal plant, they are typically rows of fans. Depending on the power plant, the water is then returned to the river, or rerouted back into the power plant as cooled water for re-use

They use wastewater
Edit cause fatfingered send- Nuke plants use massive amounts of water. Hence why they are typically built near rivers. However, obviously, desert areas don't have this luxury. So they use treated wastewater as a water source. That said, there technically is water almost anywhere. The issue with most areas like these, is that water has high mineral and salt content. Then there's also the issue with local landowners, who the power companies would have to cooperate with in order to drill for it. Arizona does have waterlogged areas where water can be found, but as with all drilling, those permits need to be issued by the State and the locals

It's just something psychologists come up with for buzzwords and talking points. Then you have people going along with it and saying things like "yup, that's me. I did that. I felt that way before." When really, this is no different than a horoscope. What? People don't want to believe it when a loved one is going to, or has passed away? YA DONT SAY! lol......

No idea why either. People have asked me before what the deal is with Nebraska. I always just say that I have absolutely no idea why Nebraska is so obsessed with the Hawkeyes, because nobody in Iowa gives any shits towards Nebraska lol. It's just kinda weird
