Five Times the US Almost Nuked Itself

kdawson writes "io9 has a scary outline of five times the US came close to accidental nuclear disasters. Quoting: 'In August of 1950, ten B-29 Superfortress bombers took off from what was then called Fairfield-Suisun Air Force Base in California, headed for Guam. Each was carrying a Mark IV atom bomb, which was about twice as powerful as the bombs dropped on Japan at the end of World War II. Shortly after takeoff, one of the B-29s had engine trouble. On board was General Robert Travis. He commanded the plane to turn back to the base when the landing gear refused to retract. Sensing the plane was going down, the pilot tried to avoid some base housing before crashing at the northwest corner of the base. The initial impact killed 12 of the 20 people aboard, including General Travis. The resulting fire eventually detonated the 5,000 pounds of conventional explosives that were part of the Mark IV. That massive explosion killed seven people on the ground. Had the bomb been armed with its fissile capsule, the immediate death toll may have reached six figures.'"

    In the case of the Travis accident, there was no nuclear disaster precisely because the nuclear core was not loaded. The Air Force was all too aware of the number of B-29's that crashed on or shortly after takeoff and never armed the weapons until they were close to the target area. To call this a "close call" is simply fear mongering to get page hits.

It isn't like a conventional bomb where you just use heat or electric current or something. It requires precise operation because you more or less crush the radioactive material. Timing is critical, dimensions are critical, etc. So even presuming you know how to build one, it isn't so easy to actually make it work.

      The flip side of that is they only go off if detonated properly. If you just set fire to some of the conventional explosives to cause them to go off, then it is almost impossible for it to cause the right kind of reaction to set off the nuclear bomb. Even if you don't really take any special design safe guards, it is still pretty hard to set off the nuclear explosion without meaning it.

      Nuclear weapons area very easy to make IFF you have the materials for them. The most difficult part is either getting the enriched uranium OR plutonium (even more difficult).. After you have the materials, it's very easy to make a bomb. So please, stop speaking out of your ass.

      A working nuclear weapon is not easy to make. Seriously, do you think the entire Manhattan project was solely about obtaining the requisite amount of fuel?..

      Merely pushing two pieces of nuclear fuel together to form critical mass are not sufficient to set off the explosion. If you do it slow, they'll just heat up and start melting. If you do it kinda fast, they will start exploding, but the force of that explosion will blow the bomb into pieces before most of fuel reacts, so you'll just have a moderate-size conventional explosion. The problem with making a working weapon is putting the critical mass together really fast, and also making it stay there for as long as it is needed to get the substantial part of the fuel to react. This is not easy by any means.

      Gun-type assembly is relatively easy, but 1) it does not work with plutonium, 2) you therefore need much more uranium since its critical mass is higher, and 3) still only a minor part of that uranium actually produces the explosion, the rest is wasted when it's blown up into pieces. It's not completely trivial because criticality is actually achieved before the bullet runs into the rest of uranium (neutrons can travel between two pieces), and it may blow the bullet off the path, preventing a full-scale explosion. So it's not your common gun.

      So, basically, yeah, it's not that hard from an engineering perspective to build a gun-type assembly (but still not something you can do without some specialized knowledge), but it's prohibitively expensive due to the sheer amount of uranium that needs to be obtained, and its efficiency is rather low - it won't wipe out a whole city.

      Implosion design, which lets you achieve significant yields even with pure fission weapons, allows the use of plutonium, and is much more efficient. But from an engineering perspective, the thing is much harder to make due to precision requirements to get everything just right; even a slight misalignment results in a fizzle.

      From the wikipedia
      http://en.wikipedia.org/wiki/Mark_4_nuclear_bomb
      " In addition to being easier to manufacture, the Mark 4 introduced the concept of in flight insertion or IFI, a weapons safety concept which was used for a number of years. An IFI bomb has either manual or mechanical assembly which keeps the nuclear core stored outside the bomb until close to the point that it may be dropped. To arm the bomb, the fissile nuclear materials are inserted into the bomb core through a removable segment of the explosive lens assembly, which is then replaced and the weapon closed and armed."
      So as you can see not armed == no nuclear material in it and yes they can and did put it together in mid-flight.

      Hell look on the civilian side, at Three Mile Island. The "Worst nuclear disaster in US history." Even with a rather major screwup making the problem so much worse, something the NRC discovered, it still didn't release any significant amount of radiation,

      To quote the NRC documentation of the incident A significant release of radiation from the plant's auxiliary building, performed to relieve pressure on the primary system and avoid curtailing the flow of coolant to the core.

      The gamma radiation monitors on the top of the auxiliary building were not designed to measure such high concentrations and they went off the scale when the accident *began*, the release of contamination went on for several *days* after. Estimates were based on thermoluscent dosimeters on the fence and Alpha and Beta emissions weren't even measured. So, in reality, the amounts of contamination released were beyond the Nuclear Industry capability to measure.

      Because of the weather conditions it was known that emissions from TMI travelled a long way and were measured in Albany, NY. Joeseph Hendrie (former chairman of the NRC) was quoted (at the time) "We are operating almost totally in the in the blind, [Governor Thornburgh's] information is ambiguous, mine is non-existent and - I don't know - it's like a couple of blind me staggering around making decisions." - So if they didn't know, how is it you do?

      Expert measurements of radioactive iodine in farm animals nearby revealed Nuclear Industry estimates of contamination released to be 'grossly underestimated'. Radioactive iodine, plutonium, strontium, americurium, 172,000 cubic feet of high level radioactive water, large quantities of krypton 85 and later that year 8 million litres of radioactive water containing tritium that were evaporated deliberately were all part of the elements released.

      Dr. Michio Kaku, professor of Nuclear Physics at the City University of New York, was quoted to say of TMI "It appears that every few months, since 1990, a new estimate is made of core debris, often with little relationship to the previous estimate. Estimates range form 608.8 kg to 1,322 kg... This is rather unsettling....," he concluded. "The still unanswered questions are therefore: precisely how much uranium is left in the core, and how much uranium can collect in the bottom of the reactor to initiate re-criticality." Which means the containment building contains enough radioactive elements to still be capable of releasing *extremely* radioactive elements into the environment.

      not enough to cause any adverse health effects (and it has been studied for decades now). That's pretty fucking good, if the worst it gets is a case of "Nobody got hurt."

      Dr Carl Johnson, an expert in radiation related diseases asked the NRC and DOE to do a survey to look for some of these elements in the respirable dust around TMI after the accident and they refused. So if the authorities *refused* to take measurements on which to base long term cancer studies, how can a supposition be made about how many lives have been lost?

      What we do know is of the states highest in the list of cancer averages (within the cancer incubation period after the accident) the ones with similar population density surrounded Pennsylvania, where TMI occurred. New York with roughly 3 times the population, which topped the list, was also in the fall out zone. So it's easy for anyone to say that no-one died because of TMI because there is no gathering of data, no official study, no evidence. It's more honest to say "We don't know how many people died as a result of TMI because because no data was collected".
