Westburo claimed that Anon went after them which Anon quickly denied. The response from Anon http://anonnews.org/?p=press&a=item&i=449

Cool story bro!

But the Republicans are Right (angles)! Thank you ladies and gentlemen I'll be here all week. Try the fish!

One:

An excursion event in a reactor isn't even close to the kiloton range (the one in reactor 4 at Chernobyl was only 33GW). The explosion you mentioned at Chernobyl was enough to toss a 2200 ton slab... but guess what... it was just steam radioactive as hell due to contamination from damaged rods (normally water in reactors when irradiated creates N-16 which is a short -lived (as in a few minutes) alpha emitter) ... but still just steam. The amount of force in the explosion at Chernobyl was only about 10 tons. Enough to totally jack up the core and it's fuel/control rods but not vaporize the plant which is what would happen if you got into the kiloton range.

Second:

Critical mass only means you've got enough neutrons to maintain a fission reaction, that's it, scale has nothing to do with it. The neutron flux between rods is moderated by steam, water, and other neutron absorbers, adding more fissile material into the equation doens't equal more energy. In fact it can STOP your reaction as enough material will absorb neutrons but not emit them with enough energy to really do anything.

Third:

Yes there is such a thing as passive cooling systems that require no moving parts. Most nuclear subs use molton sodium as a coolant and natural convection moves the sodium in a loop. Fukushima had such a thing but it the command lines to that value were cut and power to open the valve wasn't there anyway. That still didn't matter as the valve could be opened by hand except that the radiation in that part of the plant was too high. Some estimates but it at almost 30Sv MINUTE and no matter how fast you ran or with how much protection you'd still be dead before you could open the valve.

Fourth:

Dumping cold water into a reactor, especially sea water, is a big no-no as that'll immediately cause an excursion in 99% of situations, passive cooling or not. The water would stop the reaction immediately but the excess neutrons would have no place to go, as the water attenuated the neutron flux, and would MELT the fuel rods in a few minutes. If it's sea water you also get corrosion. When ordinary water is irradiated with strong alpha it becomes corrosive, reactor piping is designed to deal with the chemical reaction (peroxide) and so isn't in any danger as long as procedures are followed. Sea water on the other hand is corrosive against the same materials that are generally inert against irradiated water.

Fifth:

Fukushima had a N+2 failure system, you'd need two completely isolated systems to fail before things got ugly and the odds of that happening were extremely unlikely.

Um... what type of reactor are you an expert in as doing what you said in that last post would be a very stupid thing to do?

Jesus... where to start with your post...

First: Say it with me. Nuclear reactors ARE NOT nuclear bombs.

Unless you're dealing with highly enriched materials with proper reflectors and shape (these things REALLY matter) you're generally not going to get any sort of supercriticality, not to mention setting off a nuclear explosion isn't something that you can do just by accident. Even a simple device like 'Little Boy' requires some extreme engineering. A multistage device with a megaton yield....by accident? Not gonna happen... this pesky thing called physics will get in the way.

Second: We don't care about using unenriched uranium. That's a good thing to use as enriched uranium is incredibly dangerous to make (Bing uranium hexafloride), and dealing with weapons-grade anything is always dangerous.

Third:

Traveling wave reactors are fairly hands off deals. Most other reactors require constant attention to maintain their "balance" and if intimate knowledge of the system (along with piss poor planning and bad control rod design) is lacking then you can end up with situations like Chernobyl. If your DR plan doesn't account for a completely passive cooling system, as in Fukushima, or a dark plant... again see Fukushima.

Crickey! Will you loo' at that. We're so very lucky! You almost never see a four digit this far from its native habitat of lurking an' she's being stalked by this five digit that's almost as rare. It's times like this I'm gla' I don't work with lizards that might eat me! //Window seat please...

Thanks!

Crickey! Loo' at that. We're very lucky! You almost never see a four digit this far from its native habitat of lurking. Ah she's a beaut!

Ivan Vanko: [laughs] If you could make God bleed, people would cease to believe in him, there will be blood in the water, the sharks will come. All I have to do is sit back and watch as the world consumes you. Not that Sony was ever a God but the idea holds for any giant corporation with enough money buy the best security in the world. They were made to bleed and this won't be the last of these.

Is it me or does the governor of AZ wake up and say, "What civil liberties can I shit on today? Oh! I know! I'll start enforcing medical programs just like Big Brother did in 1984. Winston seemed to like it so much!"

Stop making sense on a Slashdot MS two minutes of hate!

I wish I could disagree with you but I know this is what happened.

Yes, there is money to be made as an investigator... a lot more to STOP the investigators. You could take every machine in my home (assuming you could find them all which is a lot harder than it sounds - take a notebook out of its case and slurp off of a line in the wall and unless they are REALLY motivated, someone generally won't find it). For all of the respect a lot of agencies get, you've got to remember that the best and brightest DON'T WORK FOR THE GOVERNMENT. Why would they? I've worked with the government enough to know this. For every competent INFOSEC professional, there're 10s if not 100s of incompetent ones. The smart ones get a clearance on their resume and then go work for six figures in the private sector. Just one thing to remember.... crypto isn't meant to stop someone... only delay them. In 1973-1974 IBM came up with a crypto algorithm based on Lucifer, the NSA took it, played with it some (they swapped the S-boxs), and gave it back, it later became known as DES. For years (and even now... which is really silly) people thought that the NSA weakened the code or put in some kind of backdoor. Why the NSA did it (and IBM knew of this method but agreed to keep it secret) didn't come out until about 20 years later. Eli Biham and Adi Shamir published a paper on differential cryptanalysis, the best method for breaking block cryptos. The changes the NSA made actually the code RESISTANT to the attack. This tells us two things. One, the NSA (and IBM) had attacks that others didn't figure out for almost 20 years. Two, they managed to keep it a secret. Hidden volumes, crypto, and solid tradecraft are all good things but when against and enemy with nearly limitless resources (and the tax-free money to rent... er hire for consultation the ones they need) you really don't stand a chance.

He was given the silly interview questions. You know like, "How many quarters does it take to reach the top of the Empire state building?". He took offense to that being:

1. Who he was

2. What he was

3. He help CREATE A LANGUAGE

I've always hated those questions, not becuase I couldn't answer them, but because they don't show WHAT I KNOW, only how I solve problems. Sure you COULD say that if you know how to solve a problem you can apply it anywhere but in my experience, knowing not only how to solve a problem, but actually creating a viable solution is far more important.

Just my two cents...
