Can Terrorists Build a Nuclear Bomb? 737
kjh1 writes "Popular Science is just chock full of good articles this month. One in-depth article addresses the question many are afraid to acknowledge is a possibility - can terrorists acquire the raw materials and then deliver a nuclear bomb? A good read that explains the difficulty in doing all of the above, while pointing out calmly that it is still possible." From the article: "Most experts with whom I spoke said that a nuclear terror attack is plausible but not inevitable, and that there's no way to precisely gauge the odds. 'I don't think the public ought to lose a lot of sleep over the issue,' says nuclear physicist Tom Cochran of the Natural Resources Defense Council. "

However, you are quite right that it would be incredibly expensive/complicated for a non-government group to obtain amounts of weapon grade uranium or plutonium sufficient for a critical reaction. And even if they would be able to build a nuclear bomb it would still be extremely hard to transport it to a place were it could be of any use for them (I know that it's in theory possible to build bombs the size of a suitcase, but it would be hard enough for a government to build such a device).

Well, given that Analog magazine published, in their April 1979 issue, a science-fact article titled "Build Your Own A-Bomb and Wake Up the Neighborhood!" which laid out in clear terms how to build a brute-force gun-type bomb, I'd have to say that the only limitation would be their ability to get enough bomb-grade nuclear material. Admittedly, the device is crude, and not transportable at all; it's essentially a two-story pipe mounted vertically in a building, with one hemisphere of nuclear material at the bottom and one at the top mounted on a heavy lead cylinder that can be dropped down the pipe. However, it's perfectly functional, and aside from the production of the two hemispheres, doesn't require anything more than basic handyman skills to produce -- the 'detonator' involving nothing more complex than pulling out a rod that keeps the upper cylinder from falling down the pipe, and getting someone willing to be there to yank out the rod probably isn't going to be a problem.
The article spends more time focussing on the problem of getting enough bomb-grade material from what was, at the time, the most accessible source of fissiles -- hijacking a truck full of fuel rods and refining the nuclear fuel to get bomb-grade material. With the breakup of the Soviet Union, it's probably a lot easier to get either the fuel or bomb-grade material directly, and getting an actual nuclear device eliminates all of the grunt work. Given the amount of effort needed to refine power-plant grade enriched nuclear fuel, the article suggested, IIRC, that a more effective use of the terrorists' effort would be to grind the fuel into a powder, take it up in a small private aircraft, and dump it out over a large city as they fly around, getting more effective distribution of the contamination. Additionally, spreading the nuclear material directly increases the cost to their target from the hysteria associated with a public announcement of the contamination and the government's attempts to clean it up, not to mention being able to repeat the attack once or twice using nothing more lethal than, say, table salt and still get the same hysteria and government reaction from the residents of the city you claim you've contaminated.

In a real nuclear bomb development program, you don't want to waste your hard-to-get HEU/plutonium on a fizzle. So, what is generally done is you take a material with similar properties to your nuclear fuel build test bombs with it (in the case of uranium, you'd use DU). Then, during the collision, you analyze the impact (for example, with high-speed X-ray analysis). This in itself requires a good amount of equipment. Even with all of the "parts" on hand, a proper atomic bomb development program will still take at least half a year and a lot of resources.
Hijacking fuel rods? That'd work for most US nuclear submarine fuel rods (which are highly enriched), but not conventional power plant fuel rods. You'll only have a few % of U235 - you might as well just refine from scratch. If you're talking about spent fuel rods, you can get plutonium out of them, but you have to worry about the differences between Pu239 and Pu240; you don't want to have to separate them, or again, you might as well just start from scratch. Plus, you have to deal with all of the other dangerous radioactive "junk" that builds up in spent rods.
A truck full of spent fuel rods would, however, make for a nice way to irradiate a large area. Put them in a big vat and set two timers: One to dump as much nitric and hydrofluoric acid as you can get your hands on into the mix to dissolve the cladding and possbly some of the fuel, and the second to dump a large tank of gasoline in a couple hours later and ignite it to help burn the radioactive compounds into the air. You should be able to cause a US-based chernobyl that way. Cleanup would be catastrophically expensive, as it was for Chernobyl; and while mass irradiation events aren't frequently filled with mass casualties, the area that they contaminate is rendered uninhabitable for several hundred years (not 10s of thousands or millions like anti-nuclear nuts pretend, mind you, but still a long time).

At risk of telling the terrorists how (like they don't already have somebody who knows more than myself telling them) I am going to lay out just how difficult it is to come up with a U-235 device. First take the U-235 and powder it in a inert gas environment. Then Sinter it like a ceramic (very hot here) into two hemispheres or use C-4 to explosively form it into a hemisphere. The latter method is probably the best and fastest. Once formed place one hemisphere on a plate of armor plate steel attached to the muzzle of an Artillery tube say 155 or so. With a fashioned shell probably best aluminum cased load the other hemisphere in the shell to be fired in the gun. Weld the whole thing severely shut with high grade steel with a few slits near the muzzle end to allow pressure to decrease but not clear through. The whole thing needs strong containment.
That is about it for the bomb building except delivery. Difficult but not impossible. The problem of getting the U-235 is difficult but not impossible and takes far less resources than in the old days. The cost is well within those of a fairly rich person. Essentially the process is to take Uranium Hexafloride and Ionize it into a particle accelerator. Taking a set of high tech magnets send the gas down the accelerator tube and the magnets will aim the streams. This process used to be really expensive of energy and such but frankly isn't very expensive due to advanced magnets developed under the US Navy's Advanced Propulsion Project and now made in China... (Anyone suspecting North Korea here is right)
It is probably pretty easy to do this by a chemical process in presence of these strong magnets as well. Something similar to Chromotography. But for those who will argue, this isn't free. It probably could be done for several million dollars now. It would be a lot cheaper in a 3rd world country where you don't care too much about the junk you throw around or the people exposed to it.

Dirty Destruction
A dirty bomb produces no nuclear chain reaction, no mushroom cloud. Yet its aftereffects could be devastating
By Michael Crowley
Although experts debate the ease of building a crude nuclear bomb, no one disputes that it is far easier to build a simpler weapon known as a dirty bomb--a conventional bomb that scatters radioactive material. A dirty bomb produces no nuclear chain reaction, no mushroom cloud. Yet its aftereffects could be devastating. In a 2002 computer simulation run by the Federation of American Scientists, a single foot-long piece of radioactive cobalt of the type commonly used in food-irradiation plants was blown up with TNT in lower Manhattan. The simulation found that a 300-square-block area would become as contaminated as the permanently closed zone around the Chernobyl nuclear plant, and that cancer caused by residual radiation could be expected to kill one in 10 residents over the next 40 years. Under current U.S. safety standards, the entire island would have to be evacuated.
Unlike a nuclear bomb, a dirty bomb can be made from radioactive materials such as cesium, strontium and iridium, commonly found in hospitals and construction sites. Experts fret about security at such sites, but the Nuclear Regulatory Commission says that because these materials decay quickly and only negligible amounts have been lost or stolen in the U.S., it's doubtful that terrorists could have accumulated enough to make even a single dirty bomb.
Dangerous amounts of material have gone missing elsewhere, however, and the U.S. is working with the International Atomic Energy Agency to inventory existing sources and, when possible, remove or lock them up. It's a monumental task, but the possibility of Manhattan becoming another Chernobyl makes it essential.

With a terrorist's bomb you will not see the massive air burst followed by a blast wave that topples buildings and vaporizes people for miles.
The most dangerous effect from small bombs detonated at ground level is fallout. This would likely be enhanced by the very structures that limited the blast radius. Surrounding buildings would force radioactive dust and debris up, making the likelihood of winds blowing the fallout over a larger area higher.
Indeed, a nuclear detonation in Manhattan would destroy several blocks and kills tens if not hundreds of thousands of people. Such an event would be devastating to our economy and to the lives of millions. IMHO this is something completely different from Cold War style nuclear scares.

Nobody makes bombs like this because of the inherent danger of accidental detonation- they could concievably go off in a crash or fire. The advantage of this type of bomb is that it's easy to make and you can be pretty sure it will go off ok (which is why they chose it for Little Boy).
"Implosion type"- a sphere of fissile material with a hollow in the middle is crushed into a critical mass using explosive lenses. This is much more efficient than the gun type due to the increased density and the detonation speed. Getting the high explosive lenses right is a real bastard though. The literatures pretty light on the explosive details strangely enough.
So, basically, your common or garden "building it in his cave" terrorist stereotype is going to have to go for the gun type.

I guess you are trying to generalize about southerns now, since NASCAR's following is mostly in the more rural section of the country.
Do you really care about what happens in a place without NASCAR, unless they are IMMINENTLY ready to attack! Like SHARKS, and ASBESTOS, and POWER LINES!!! News at 11!!!!!!"
Please. Yes, people care more about trivial events in their own country than trivial events around the world. When something big happens, it is covered ad nausem.

You: The top two stories on CNN. The headline and the one on the top right. 1. Blasts rock Baghdad, kill 20 2. Putin: Iran not developing nukes
I don't see how stories about insurgents in Iraq (essentially equivalent to terrorists, and spun as a threat to the US) and nukes in Iran disprove the original point.
As to people being naturally more interested in their local news, well, sure. But the tendancy is far more pronounced in the USA. There may be any number of reasons for it, but it's certainly the case. Let's compare the top stories on news.bbc.co.uk, for example: Aside from the Baghdad explosion, the top two stories are about Nepal and the Congo.

Anybody who thought about it at all realized that it was inevitable that a tsunami of this scale would hit sooner or later. It is an event that is, as mathemeticians say, "Poisson distributed", that is to say that it is like the decay of a radioisotope and the resultant emission of a particle. It can happen at any time, but it can be characterized by a rate, which is a probability that it will happen in some specific period of time. The rate for massive tsunamis in the Indian ocean, as it happened, was very low, so nobody was concerned it would occur this year, and or even in our lifetimes. So few people other than professional tsunami watchers probably thought the expense of building a warning network was warrented. And who knows? There may have been other investments that would have, based on mathetmatical expected return, saved more lives.
But now that it has happened, of course everyone wishes we'd spent the money to put a warning system in place. And, in fact, we almost certainly will. It's hard to say whether this is the best investment, but there are other reasons to do so I guess.
The case of nuclear terrorism has both similarities and differences. It is different, in that there is a human agency involved that would do this sometime in the next several years if it could. But they are somewhat unlikely to be able to do this, due to steps we have taken to prevent that. If we take further steps, it becomes extremely unlikely. But it never quite becomes impossible. At some point, we may be able to drive the threat of nuclear terror down to the point where it is a lot like the pre-tsunami situation. People not professionally involved will question the value of the next marginal investment in prevention. And they will, arguably, have a point. But when the disaster actually happens, hopefully some generations hence, people will have wished to have done more.
At the same time, there are other possibilities, like the killer asteroid scenario, that could use some attention. The problem is you just don't know in advance which disaster will happen to you. Choosing what to do is not simple. Suppose you are examining the possibilty that an asteroid capable of spreading the destruction of a small nuclear bomb is going to hit a population center. Suppose (hypothetically, of course) it turns out to be 10x more likely than a terrorist attack of the same magnitude. We should spend our money on asteroid defense, right? Well, what if it costs 100x as much to do something about it?
In short, you have to know the marginal value of a dollar invested in terms of incresed security.

The Poisson distribution was named after Simeon Poisson [wikipedia.org].
