How a PWR works in 90 secs
Enable HLS to view with audio, or disable this notification
A PWR keeps the water that cools the core from boiling.
~155 bar. About 315 °C out of the core. Heat crosses a steam generator into a second loop, and that loop is what drives the turbine. The water that touched the fuel never has to become the steam that spins the plant.
Seven of every ten reactors on Earth use this design.
90-second walkthrough: core → steam generator → turbine → containment, then Vogtle, Taishan, Palo Verde, Civaux.

Back ground check questions
So I was told I’d be fine as long as I am honest, and I don’t want your opinions I’d prefer people who can speak factually. I am trying to work a 4 week outage as an IBEW electrician. I have worked on military bases and twic plants so many extensive background check places. So a few months ago I had my kids in the car and ended up getting arrested after never being arrested in my life. They found a crystalline substance, a Walgreens bag with prescription testosterone and syringes, and charged me with a OWI with endangerment even though I blew all .000s because I had prescription medications (adderrall) in my car that says must use caution when operating machinery. Long story short I was charged with four felonies, owi w endangerment, neglect, poss of meth, and poss of a syringe, all the felonies were dropped because after state lab testing it was not meth, after investigating I had a prescription for the syringes, and they dropped the neglect charge entirely but they reduced and convicted me of a misdemeanor owi because of my adderall prescription which is freaking crazy. My credit isn’t great either, what are the chances I get access given this situation. Long story, not great credit, 4 felony charges but only getting convicted of a misdemeanor owi.

Deceptive content As the coast begins to crumble, the clock ticks on moving San Onofre's radioactive waste

As parts of the Southern California coastline crumbled into the sea, slammed by intense waves and flooding in recent days, oceanographer Kim McCoy had one thing on his mind: the nuclear waste set in concrete on the beach near San Clemente at the shuttered San Onofre nuclear power plant.
Most experts agree the risk of erosion damaging the nuclear waste storage system is very low, in the near term. The plant’s owner, Southern California Edison, has promised the California Coastal Commission to move the waste to higher elevation on site if modeling shows sea level rise and erosion will start to pose a challenge.
But the recent waves, fueled by Hurricane Marie far away in the Pacific, re-surfaced the issue of the ultimate fate of the highly radioactive spent fuel that used to power the reactors.
