An explosion has been reported at Georgia Power Plant Bowen. Injuries have been reported via scanner traffic, number and extent are unknown. The source of the explosion is believed to be a turbine within the powerhouse.

*** A couple of days in between we had a power switch arcing at a third power plant.***

Probably a cheap FEDERAL PACIFIC brand breaker. Replace with TOSHIBA.

As for what happened at the nuke Plant at Russellville, it appears they were attempting to place the stator on a railroad car in the crane bay and the crane failed.

From the looks of it it was not a standard crane that goes across the turbine floor, but a special mobile crane for extremely heavy loads.

Read a report where they stated power failed to the crane. Obviously a make shift crane might be more affected by loss of power under load then a permanently mounted crane on rails.

Channel 2 News just showed a very large dark stain on the side of one of the chiller towers and speculated that was possibly a result of the explosion.

I've been inside those type natural draft water cooling towers. It is hard to imagine anything in there being the source of the explosion.

The hot water is sprayed in about 1/3 of the way up from the bottom. The spray continues down across a multitude of plates, dishes and other material designed to give the splashing water a convoluted path falling back to the bottom.

The splashing, spraying water warms the air, giving up heat from the water. The natural rising of the heated air draws in more air from the open bottom. The curving shape creates a speed up to the rising air drawing in air faster and giving more cooling.

In short, that is a big open concrete tube with a bunch of sprinklers in the bottom third. There is no containment vessel or sources of ignition inside it. There is one heck of a draft and an incredible amount of "fog".

That picture doesn't look like a stain to me, it looks like a place where water is seeping out from the inside spray.

Here are PHOTOS of what happened in Russellville! It appears to be a MAINTAINANCE accident, not a nuke accident.

He doesn’t get out until 7-17-2017 barring any other factors.

Thank you for the clarification. I love this stuff.

Ahh. Water saturating right through the thin concrete. Interesting theory. Looks a little dark for that, but maybe. I saw pictures of the other cooling towers, and it looks like they can exhibit very dark streaks if it's been raining.

I didn't know that they actually fill up any of the interior volume of the tower with the evaporator material and spray heads; I thought they were all arranged around the outside perimeter of the tower, at ground level. Thanks for the information.

Someone told me (long ago) that the concrete at the narrowest part of the tower is only two inches thick or so. It's easy to see vertical rebar in the damaged tower.

Yeah. Embarrassing. A career-ender for someone, I'm guessing.

Who you talkin' about? Some Arkansas inside skinny? Some techie-dishey?

Pardon sir,

Did you really just say Herculean Turducken?

LOL!

That “stain” is water, plain and simple. I have lived by the plant my whole life, and been there many times. Whenever it rains the water stains the side like that. The last report that I saw and the guys that I know that work at the plant said it was turbine #2. In regards to what someone said about nuclear power, this is a coal plant (the largest in the country and second in the Western Hemisphere). Only a few minor wounds, most were treated on site. A lot of emergency crews were dispatched from neighboring counties but only remained for an hour or two. A lot of people are being kept on site though (the restaurant I work at sent food) and I herd reports of a few stranded on various floors, but I’m not sure.

Odd the other towers were not similarly “stained” with water

That was the tower I was in at the Gavin Plant in Southern Ohio. There are likely different designs for different plants, especially those built in significantly different time periods.

Bowen was at one time the largest coal powerplant in the U.S. and maybe the world.

I worked there for a quarter as a co-op engineering student ~35 years ago, and am somewhat familiar with the plant layout and equipment as a result. There are large natural draft hyperbolic cooling towers, but there is very little inside them, nothing likely to create holes if it failed.

If one of the main steam turbines failed catastrophically, the hole(s) would be in the turbine house structure, which is the long low part of the main powerplant structure. The high part houses the steam generators, AKA “the boilers”.

I will now read the thread to see what else we’ve learned about this story beyond the OP.

That is correct. They run 100-car “unit trains” of coal into the place all the time, multiple times a week. Or did when I was working there.

That’s definitely the turbine house.

Bowen is not a nuclear plant. Coal-fired.

They mixed air and H2 during a generator purge and it blew up.

Air and H2 in the generator during a purge procedure blew up. There is never, ever supposed to be a mixture of H2 and air during the purge procedure. H2 is purged with CO2 to 95%+ CO2, then the CO2 is purged with air. When regassing the generator the air is purged with CO2 to 95%+ CO2, then the CO2 is “purged” with H2.

***Air and H2 in the generator during a purge procedure blew up.***

Good grief! Don’t they have a checklist to go by for this procedure? Did the sealing oil also catch on fire?

There is no excuse for purging H2 with air!

No kidding!

There are other stories that say the same thing if you google “Bowen explosion purge”. We had pictures of the damaged generator at our plant, our #2 generator is a Westinghouse very similar to the one that exploded.

Wow, that’s a really basic operations screw-up.
