    After the Chernobyl disaster, a Russian organization of Chiropractors volunteered their time and set up shop in a nearby Ukraine school gymnasium.

    Over 3,500 people visited and had spinal adjustments which helped improve nerve function to the thyroid gland, which is so important with radiation poisoning. NOT A SINGLE PERSON WHO VISITED GOT CANCER!!!

    Think about that next time you visit an "MD". Chiropractic is where it's at.

      Failing that: Where were these patients from (how close to the disaster)? What level of radiation were they exposed to? For how long? Would level of radiation exposure significantly increase their cancer risk? How long were the patients followed up on after receiving treatment? Is this long enough for cancer to have developed? etc...

    ...looking for a Gravi artifact near these old buildings, see. And the detector keeps pointing me inside, so I go. The roof is gone and the moon is out but I'm staring at the detector instead of looking around.

    All of a sudden I bump into this bloodsucker, and he's taking a leak. I look at him and go "hey, buddy, why are you pissing in the middle of the building?" And he looks back at me and goes "what the hell are you doing in my house?"

    So I look around and realize we're in the middle of a converter room for a substation of the nuclear power plant. There's got to be 10 million volts on the wires in there.

    About then I realize that only in the Zone can you walk right past a bunch of giant warning signs, into a room full of enough electricity to kill you faster than the speed of light, and the only thing out of the ordinary enough to make you notice is a blood sucking mutant taking a whiz."

    which is fine when you are talking about space exploration or computers. but nuclear power?

    the problem is, accidents happen. they always do. no long winded speech on safety will alter the inevitable. corners are cut, economic considerations bypass longterm challenges, things break and fall apart over time. eventually, you have a nuclear accident. well now, it's a matter of the consequences of the accident. well: you blow up an oil supply depot, collpase a coal mine, undermine a dam, etc: these are awful cataclysmic events. and 5 minutes after it happens, its over. but nuclear power, when you have an accident, it stays with you for centuries. that's the big problem with nuclear power

    mankind being too confident in his technological mastery, combined with longterm effects outside of the realm of mankind's normal psychological considerations, and you can see the problem with nuclear power. mankind, in a way, isn't built to handle nuclear power safely, and so we just shouldn't use it

    i'm not saying we have better alternatives. and nuclear is great, when it works. and it works 99% of the time. but the problem with nuclear, when it doesn't work that 1% of the time? unlike every other power source, really terrible consequences stay with you for centuries. and so that 1% changes everything about nuclear power in ways that any conscientious person finds very troubling and sobering

      when a hydroelectric damn collapses millions can be left homeless and tens or hundreds of thousands can be left dead and it can take years to repair the damage and rehome those left homeless.

      After a regular old industrial accident huge tracts of land can be left unusuable effectively forever when regular non-radioactive poisons and heavy metals leave the land unusable.
      There's lots of mutagens which aren't radioactive but will still give you cancer and deform your children and which have no halflife. they're forever.

      nuclear can be dangerous but fundamentally it's not game changing.
      slag piles and lead don't just stay with us for centuries, there there forever.

        I have to say I'm very much on the fence on this one. In my youth I was definitely against nuclear power, then later I was a strong supporter. Now I'm back to being not sure.
        There's a big problem if, for example, you had perfected the containment process, then out of the blue, a Tunguska sized event (http://en.wikipedia.org/wiki/Tunguska_event) happened nearby (or on top of) your nuclear sites.
        The fallout from that would be impressive.
        A Tunguska sized event is a "lesser risk" that we all live with every day, yet it did happen, and very probably will happen again within a few generations.

        You forgot about the waste and the decommissioning of nuclear power stations. The former we haven't solved, and the second, well, lets just say that I don't trust the nuclear industry and the economy enough to be responsible for decommissioning. Then there are things like wars, which tend to alter stuff. Anyone here that wants to decommission a nuclear power plant that is in the middle of a conflict? Or 5m deep in a flood? Hell, even Chernobyl is more than 500 million short for the next concrete sarcophagus, which should last some 100 years.

              the research on that was shut down due in large part to anti-nuclear campaigners. Apparently "no nukes are good nukes" to them even in the case of ones which burn nuclear waste.

              • According to most it was shut down because of large overruns caused in turn by technical problems. Which is in some ways sad, because I'm certainly not against research regarding newer reactor technology, even with regard to breeder reactors (which - according to my research so far - are technically more complicated, not safer than the latest regular reactors and don't solve the waste problem, just reduce it).

          Actually, the waste is a pretty much solved problem if the political process will kindly step aside and let us recover the 95% valuable fuel from the "waste". The remainder needs 200-500 years to decay to background levels.

          I'm pretty sure if a shut down and de-fueled reactor is in a war zone, people are more endangered by the IEDs and bullets whizzing around than by the old nuke plant.

      We need a way of generating a lot of power, and nuclear is the best of what we currently have. Though maybe we should build the power plants away from big cities and (more importantly) from areas where earthquakes and tsunamis happen.

      You seem to be ignoring the fact that Fukushima went online in the 70s and operated w/o incident until a 9.0 earthquake struck. Chernobyl's safety deficiencies are well documented, so I'll not be addressing them here.

      There are newer reactor designs, materials and technologies that could mitigate the threat of nuclear meltdowns even further.

      There is an underground coal fire in Centralia. Pa. [coalminingappalachia.com]. It has been burning for decades and will continue burning for the forseeable future. Due to sudden pockets of CO2 and carbon monoxide along with sink holes suddenly opening up (with an intense hell-like fire at the bottom), the entire area is unsafe and will remain so.

All with the primary coolant shut down in an attempt to get the water hot enough to drive the turbines again.

          • You've got a couple of facts wrong there.
            First, they have not pulled all control rods out, only most of them (which was not forbidden). They also haven't driven the reactor to higher than designed power levels - the reactor was working at 200 MW thermal, which is like 6% of its nominal power. The diesel generator for emergency cooling was also already up and running at the moment of SCRAM.

            Anyway, if the reactor struggles so much to keep power even when most of the control rods are up, then it looks like a s

            • by sjames ( 1099 )

              Actually, there is very little more dangerous than trying to burn past xenon poisoning without the cool down time. As soon as you make headway, the reactor tends to naturally run away (just like what happened). That is, it creates a strong and fast positive feedback situation.

              From http://library.thinkquest.org/3426/data/disaster/timeline.html [thinkquest.org]:

              1:00-1:20 am The operator forced the reactor up to 7% power by removing all but 6 of the control rods. This was a violation of porcedure and the reactor was never built to operate at such low power. The RBMK reactor is unstable when its core is filled with water. The operator tried to take over the flow of the water which was returning from the turbine manually which is very difficult because small temperature changes can cause large power fluctuations. The operator was not succesful in getting the flow of water corrected and the reactor was getting increasingly unstable. The operator disabled emergency shutdown procedures because a shutdown would abort the test.

              So, not ALL were removed, but more than permitted were and under low coolant flow conditions with the automatic SCRAM disabled in an attempt to burn past the xenon poi

Most of them are nuclear workers and associates. But a few eccentrics have apparently moved back to their villages too (the article talks about an encounter with one old lady who lives there, completely cut off and on her own). I also didn't realize that the other reactors of the plant were kept online long after the #4 reactor was entombed (the last reactor wasn't shut down until 2000). It's also amazing to see how much work has really been done to clean the place up (it's now safe to walk around most of the area, with a guide who knows the really nasty "hot spots" anyway).

    Whoever wrote the article had no clue. Chernobyl consisted of a steam explosion followed by a graphite fire of the exposed reactor core. There may have also been a subsequent brief prompt criticality incident that released less energy than the steam explosion, however the article implies that Chernobyl's radiation release was entirely by a bomb-like nuclear explosion.

    • Absolutely true, but I think there would have been a problem with a larger steam explosion if the melting core would have reached water under the reactor. And nuclear blasts aren't that dangerous regarding radiation levels (if anyone within a reach of 50 km is injured, they don't need to be either). Nuclear reactors definitely are, they are basically huge dirty bombs.

The main difference between a runaway reactor and a bomb is that the latter is built to optimise the rate of the reaction, and that's also why it has more devastating effects.

    I was a child in Germany when this event occurred and it did manage some interesting changes. I was six at the time and the school I went to had several tents set up outside the school where men in interesting orange, white or yellow suits would give you a once over with a geiger counter before you were allowed in. I know there was another tent set up a distance away for kids who came in 'hot', but I don't honestly remember what went on in the tent as I was always 'clean'. No recess outside for a whole year (a bunch of pent up 6 year olds is a scary thing) and if you were outside, under no circumstances were you to touch anything or put any of the plants (like blades of grass) in your mouth to make whistles. I know there were probably more rules, but I was six at the time and didn't care much outside the "some Russians made it so we can't play outside" angle. Was a military brat. I say this because since then I have read up as much as I can on the incident and am extremely interested in the history behind the disaster. I have even looked into getting one of the CHERNOBYL LIQUIDATOR medals to add to my small collections of all things Chernobyl. The lead up to the actual disaster itself is very fascinating and I encourage people to read into it. It wasn't so much a sudden 'oops!' as it was a lapse in several security and communications measures that lead up to the eventual steam explosion. The descriptions from some of the poor unfortunate first responders is enough to send chills up anyone's spine. Particularly the one I read (looking for link now actually) from a firefighter that died shortly there after describing the sensation as 'millions of hot pins and needles all over ones body'. Other interesting aspects from this were talks of the plant design itself, as well as photos of the nearby towns and abandoned villages. If anything this disaster was a wake up call for a more standardized plant design and communications methodology. My mind doesn't serve me well but the Russians had a habit of making each plant unique (someone correct me if I'm wrong?) and thus how to contain this particular disaster was by the seat of the pants moment. Oh, and if you get a chance, find the remains of the plant via google maps. I am not sure if it is still up but a year ago you could see the concrete tomb from the skies. Also look for some of the 'on site' photography done. The picture of a pipe 'oozing concrete lava' was morbidly fascinating.
