I remember when they dropped the reactor shell up by the carpenter shop. Good times.

South Louisiana is already at Fallout 76 stage
A little more mutation and destruction isn’t going to be noticeable.

I trust Entergy to keep me safe.

They built their emergency backup power (diesel generators) below the flood line... Poor planning.

I just talked to Maurice at starlite and he has a pod being built for me.

IF they shut down the reactor, and there is no incoming source of electric power from the grid, they are dependent on diesel generators to circulate cooling water through the reactor to prevent core melt. How long the cooling must continue depends on who you ask, seems to range from 2 days to two weeks to go from shutdown to the point where cooling is no longer required. Hopefully they have enough diesel on site.
They will still need to keep water aka cooling on the fuel including the spent fuel which takes power to the motors for the pumps. Plants are still storing their spent fuel on site and not dry storing them. Diesels are meant to give time to get to safer offline operation where power demand is low until you can get offsite power restored. Depending on what caused loss of offsite power, it could be bad news for nuke plants around the country if you are talking about some doomsday event.
River Bend could easily be another Fukushima if humans abandoned it before removing all fuel.

before Fukushima fudged things up. IIRC their reactor design is different than ours (they use graphite) , and that made it susceptible to the incident.
You are thinking of Chernobyl, Fukushima was GE BWR reactors of very similar design to River Bend.

At the end of the day nuclear power is very safe . Fukushima was a disaster and there were zero deaths from actual radiation . The uptick in cancer rates in the future is debatable . Think about Chernobyl, despite the dooms day predictions nature has returned pretty well to the surrounding area . The US is pretty good with safety on these plants. Could a major disaster happen? Sure but there are bigger things I would worry about

Agreed, but looking at it from a doomsday/prepper angle, you better off being far away from one in that type of event.

Redundant systems that all run on the three massive generators on site. One generator can run all the systems needed to keep all the fuel rods properly submerged and water flow to keep the water circulating through heat exchangers to prevent overheating. If all that fails the containment building is designed with safety features inside of it to prevent hydrogen from building up. The last defense is the containment wall is six feet thick with massive rebar in it. It can take a direct hit from a commercial jet and the only thing that would happen is it would leave a black mark on the concrete wall. One other thing is all the control circuits for the equipment in the safety systems are analog control devices so they won’t be affected by an EMP device.

Very good explanation. Ther is at least one NRC inspctor on site and usually their are two. The NRC also rotate inspectors around every two years to prevent a company an an inspector to get a little cozy, if you know what i mean. You are correct about the fukashima design. Reactors around the world are not even close in safety specs as the US reactors

Those beams weren’t in incased in 6-10’ of concrete

I used to work at River Bend. Working at one of these nuclear plants makes you realize how truly safe they are, at least in the U.S. It would take such an inconceivable combination of human error and mechanical failure for River Bend, or pretty much any other reactor in the U.S., to melt down.

More people have died in Ted Kennedy’s Oldsmobile than in U.S. nuclear accidents.

Much was learned from Katrina and then Fukashima about the placement of generators and fuel supplies.
In hospitals for example, generators and fuel supplies are not required to be located no lower than the third floor.

And the concrete used is very different in its properties. It might as well not be the same material.

There is a hospital under construction down the road from here, the backup generator is at ground level, as are the ones at every hospital I worked in until I quit in 2010.
