    From what I read about the Chernobyl disaster it wasn't really the reactor design that was at fault but the dangerous experiments that were being carried out at the time.

    "The disaster began with a routine operation for maintenance and fuel change that commenced a day before the accident. In addition to these procedures, the technical crew wanted to perform a test of the plant's steam turbines. Their goal was to determine if the turbines would continue to provide power for the plant's safety systems after their steam supply was cut off. While attempting to perform this test, they committed a series of errors that culminated in catastrophe. More than simple blunders, the errors stemmed from a reckless disregard for safety procedures. The errors compounded, and the disaster would likely not have occurred if any one error had been avoided.

    The crew began by reducing the reactor's power so they could start their experiment. They also switched off the reactor's emergency core cooling system. This meant that in the event of a malfunction the reactor would become dangerously hot, which is exactly what subsequently happened. At 12:28 A.M. the crew made another serious error by putting the reactor's regulator at much too low a setting for the planned experiment. At this point, the reactor should have been shut down and the experiment abandoned, but the crew feared a reprimand for the incorrect regulator setting, so they decided to bring the reactor back up to power. To do this, they removed most of the graphite rods that moderated the fissioning of nuclear materials in the reactor core. By 1:00 A.M., the power output had reached 200 MW, still too low for the experiment. At this point, they switched on two extra pumps for the circulation of more cooling water in the core. This action made the reactor highly unstable, and water and steam levels began to oscillate uncontrollably. The crew then made another major mistake by blocking the automatic shut-down system. At 1:23, they started their experiment, and a few seconds later they switched off the safety apparatus that would have come into operation as soon as the turbines stopped.

    In less than a minute, the crew chief realized that he had a serious problem, and he ordered the graphite rods to be reinserted in the core. The rods did not fall home, probably because the rods or the nuclear fuel had been distorted by the heat. The rods were then disconnected so that they could fall into the core, but by this time the situation was hopeless. The reactor's power surged from 7 percent to several hundred times its normal level. An explosion rocked the core, followed by another one 4 seconds later. These explosions blew the roof off of the reactor and caused the collapse of a refueling crane into the core, destroying what was left of the cooling system. A reaction of the steam with the fuel rods' zirconium cladding caused the formation of hydrogen, which then ignited, setting off 30 separate fires through the plant. The graphite in the core also ignited."

    Actually, it *was* partly the reactor design that was to blame, as well as operator error.

    The Chernobyl design had control rods entering the core from top and bottom. This particular design causes the reactor to have, in certain operating regions, a positive temperature coefficient of reactivity (like positive feedback for you non-nukes.) This has the effect of the reactor power level rising in response to a rise in temperature - and in response to the bottom control rods rising into the core.

    Western designs are almost all designed to have a negative temperature coefficient of reactivity in operating regions.

    What happened was, as the reactor temperature rose, power followed, such that when they finally tried to shutdown the reactor, reactor power level shot way up (basically, the reactor went prompt critical - some experts have said that the reactor went prompt supercritical - I'm not sure myself since I'd have to go back and research the values for beta and beta-bar that Chernobyl was designed to.) As a result, the power level exceeded design values by a couple hundred times, and the resulting step rise in temperature and pressure caused a massive steam void to form in the reactor, which promptly escaped by rupturing the top of the reactor.

    Had Chernobyl been built to western designs the disaster wouldn't have happened.

    1. Cooling and fuel channels containing thousands of welded joints through which the coolant continually passes vs. a western design consisting of a single pressure vessel that holds the majority of the coolant covering the core with a few loops to circulate water to the steam generators. This makes the design much more prone to a leak in an inaccessible location.

    2. Using graphite instead of water. Graphite has its uses - a power reactor is not one of them.

    3. A positive temperature coefficient of reactivity. If you do *nothing* else, make sure your design has a negative coefficient in all operating regions.

    4. A flimsy steel shed vs. a proper containment. Even when the reactor suffered a steam explosion, a proper containment structure would have caused Chernobyl to be a localized accident resulting in the contamination of the inside of the containment structure, instead of a disaster affecting the entire world.

  35. My Uncle Was In Chernobyl And He Survived It by $criptah · · Score: 5, Insightful

    My uncle was a member of one of the first rescue teams that were sent to Chernobyl after the disaster. This might be slightly off topic, but if you think that the pictures of the empty city are disturbing, take a look at people who were there after the tragic event.

    I hate a lot of things about my former country, the Soviet Union, and its leaders. One of the things that I hated the most was the fact that people were never told the truth. In May of 1986 my uncle was told that he had to go to Chernobyl to help patch things up. Since he was a memeber of an elite task team that was a part of chemical forces, a special unit within the Soviet Army, he had no other options. He went there in May and he spent some quality time there. His major task was to drive tons of cement to a helicopter that would drop it off on the damaged reactor.

    The not-so-funny thing was that nobody who was in my uncle's shoes knew what was going on there. The superior officers, had to tweak radiation meters down so nobody could find out the real level of radiation. People did not have proper protection, tools to work with; moreover, the Soviet leaders did try to play things down a notch. Afterall, how could a superpower have a major disaster?

    Out of all of my uncle's rescue team, only a dozen or so people are alive now. All of them are disabled. My uncle has problems with his eyes and due to this fact he had to quit his job: he was a professional photographer. The Ukranian government pays him a small pension, not enough to buy food for a week. His immune system got reduced down to 60% of what he used to have. Still, he's better than his son. My cousin's system is 40% of the normal level. I remember reading a newspaper about a woman who had to buy a bottle of vodka every day. She did it because her husband could not surive through pain without it. Just as my uncle, he was in Chernobyl trying to fix the Soviet problem without exposing it to the rest of the world. That guy was lucky. His kids had been born before he went to Chernobyl. You won't believe how many stories I've heard when people just wanted to die without pain and suffering.

    Finally, here is a surprise for you. Chernobyl is not the only empty city. In fact, if you want to see more of them, you should travel to southern Belarus. See, due to the winds and the rain that happened right after the disaster, most of the radiation that escaped in Chernobyl ended up miles away in the neighboring state. In fact, Belarus recieved more damage than the Ukraine due to the wind pattern for that day. Most of the winds blew from the Ukraine straight into my motherland and the damage was done. I was lucky. Although I was in the rain that day, most of the radiation passed around my town. However, many towns received a solid amount of radiated water but the government did not do anything until it was late. As I said above, the government did everything it could to cover up the problem.

    We were told to burn our clothing and take a shower. That is it. That was the f*cking Soviet solution to the problem. Months later dozens of small towns were evacuated. People left leaving everything behind in hopes that they would return. Return my ass. The only people who returned were either looters or bums who scored nice houses where they could live. Years later, after the Soviet regime had collapsed, some reporters were providing us with information places that were emptied out. Most of these places are still there. They are a real time machine. If you go there, you'll see pretty much everything as it was in late 80's. Pictures of those places are distrubing, but not as bad as pictures of kids with cancer or disabilities due to the Chernobyl disaster. As for me, I am afraid of having a child myself. Who knows what got inside of me during that f*cking rain... All I know is that some of my friends started to develop problems already.

    Have a nice day.
