Honestly thankful that most of these installations were hardened after 9/11.

[–] originalucifer@moist.catsweat.com 45 points 2 years ago (3 children)

these facilities were already hard-core protected, long before 9/11. i grew up next to one, the security described that stopped this guy existed, and was in use 40+ years ago

post 9/11 actions didnt do shit to help anyone, anywhere... it was full of sound and fury, signifying nothing.

[–] snooggums@kbin.social 28 points 2 years ago (2 children)

They did beef up the cabin doors to the flight crew, so they did one thing based on what actually happened on 9/11.

[–] pdxfed@lemmy.world 17 points 2 years ago

Yes, thicker cabin doors on planes with trillions spent on security theater and invading places that didn't cause 9/11, unlike the 15/19 hijackers from Saudi Arabia.

In the UK they took the bins away for a bit, but then it got annoying so they brought them back, and added an announcement to say basically that if you see a terrorist being a terrorist you should probably tell someone, thank you.

That'll stop them.

[–] Hobo@lemmy.world 1 points 2 years ago

If they're a terrorist they have to tell you. It's the law.

[–] Madison420@lemmy.world 2 points 2 years ago

Accurate, there's more security now but you would have to know what to look for to find it.

[–] pete_the_cat@lemmy.world 2 points 2 years ago

Yep security and structural integrity at a nuke plant was a thing decades before 9/11. I grew up about 30 miles away from Salem 1&2, and Hope Creek in Southern NJ. My dad was an electrician that worked there while they built them.

They were hardened as they were built in the 70s, 80s, and 90s. They all pretty much have 30 foot thick concrete walls in the containment building that houses the reactor(s). The Nuclear Regulatory Commission doesn't want something like Chernobyl to happen, which had no containment building, just a normal structure. Even if a US reactor goes supercritical and melts down, there is about a <1% chance of any radiation leaking out. If the reactor exploded the building would withstand the explosion and vent the pressure into the atmosphere, which may contain small amounts of radioactive alpha and beta particles. The only nuclear accident we've ever had was Three Mile Island in Pennsylvania and that was because the safety valve in the containment building got stuck open after venting the pressure after one of the reactors went critical.

Even three mile island wasn't as bad as most people seem to think. It was used as an Anti-nuclear propoganda piece, but it wasn't that bad. The other reactors there continued operating for several decades after, though I think they're now all shut down.

(This is true for Chernobyl too though, so I guess it really doesn't say a whole lot about severity.)

[–] Madison420@lemmy.world 3 points 2 years ago

Very true, the windscale fire is probably a better comparison between incompetence and release.

Yes three mile shut down production completely in 2019 after running at a loss for years.

[–] pete_the_cat@lemmy.world 3 points 2 years ago* (last edited 2 years ago)

There was practically zero impact to the surrounding environment after the TMI leak, I think I read that radiation was practically undetectable after like 6 months.

This is not true for Chernobyl though. That place is fucked and they needed to encase the reactor building twice in order to stop it from leaking harmful radioactive particles (x-ray and gamma particles, alpha and beta particles are less worrisome but still harmful in large doses IIRC). Pripyat is still hot and will be for like a hundred years or more, tons of people died either immediately after the explosion or shortly thereafter. Those that didn't die within the first few months developed serious health issues and cancers years later. It's literally the worst nuclear disaster in history.

[–] AngryCommieKender@lemmy.world 3 points 2 years ago* (last edited 2 years ago) (1 children)

Three Mile Island isn't the only incident, just the only accident, we have had. The only true meltdown was intentionally caused by the Army Corps of Engineers in the late 50s to test if China Syndrome was real. Thankfully someone did the math wrong so there was no danger of the core melting to the center of the earth and detonating. This is why the TVA was the last time that the Army Corps of Engineers was allowed to administer the things. Congress was understandably a bit upset to find out that they basically flipped a coin on destroying civilization at the very least.

[–] pete_the_cat@lemmy.world 2 points 2 years ago

Yeah, I meant "something that we didn't cause intentionally".

[–] Stuka@lemmy.world 8 points 2 years ago

Random dudes who try to storm a nuclear power plant are morons, regardless of security.

This dude would have no idea what to do, and I really doubt he could cause any harm beyond maybe temporarily forcing a plant shutdown.
