In a water pond beneath the reactor, loosely translated from russian: 1 - pumice-covered fuel lava, 2 - concrete added in 1986, 3 - parosbrosnye pipes, 4 - steam take-off tubes.

Oh my god, thank you Mark. This is perfect tmniig, will definitely kill some amount of my free time between the 18th and the 21st in the UK. Bloody Borderlands 2 is out on the first date in the US but not until next Friday over here. It's going to suck ...

Oh my god, thank you Mark. This is perfect tmniig, will definitely kill some amount of my free time between the 18th and the 21st in the UK. Bloody Borderlands 2 is out on the first date in the US but not until next Friday over here. It's going to suck talking to people I know in the US. If you get really stuck in a game what are you going to do? It's different from any other form of media after all, you won't get stopped halfway through Season 4 of Angel because you're not good at watching it.

The RBMK design had SERIOUS safety issues which were compounded by the night crews lack of understanding of the reactors design and operation. Dyatlov should NEVER had ordered the power level to be set so low...doing so poisoned the reactor with xenon isotopes that dropped the power level even further and lead to withdrawl of far too many control rods in an attempt to increase power. This shows how little the crew understood the reactor. The accident was due to a poor design, poorly trained operators and a complete disregard for safety procedures.

I must correct myself. The pressure relief valves were designed to relief only as much steam as produced during maximum operational power (i.e. 100%). At the time of accident, the thermal power was much higher than normal (some say at least 10 times, others even up to 300 times). At such rate, even the stuck-open valves to turbine would not make much a difference. These facts led to another post-accident improvement in NPPs design: the steam relief capacity was significantly increased.

ensd7f, I agree with you. Anyway, I think that an accident did not happen because of the improper procedures, but because the operators were conducting experiment in which they disobeyed the procedures existing at the time. The funniest thing is that they were told to disobey procedures in order to conduct the experment, but they weren't experienced enough to realize when or how to stop it. The real improvements after the accident were made in instrumentation (displaying the reactor status more clearly) and in boron rods lowering speed.

It's not even about the level of education those guys had, it's more about procedures in times of crisis, operators should not need to understand or interprate anything, but just react accordingly to certain parameters that are just facts. Dont expect people to think right, give them procedures to follow when this this and this are this way, ... I heard this event led to greatly revised crisis procedures, for the better of all of us.

People, don't criticize the engineers who created the reactor too much. They never thought that someone would manually close the valves on the steam lines leading to turbines while the reactor is peaking at 300 times nominal power. The pressure relief valves simply couldn't relief all steam produced at that time and the explosion was imminent. The operators simply didn't understand how the system was operating (the serious lack of education was in place), otherwise they would never do what they've done. I'm sure that if the steam valves remained open the turbine would take the excess steam and there would be no explosion (operators SCRAMmed the reactor seconds before explosion).

I wrotte "plumb" instead of LEAD. Sorry. I meant they would have built as a preventive measure a LEAD and CONCRETE HEMISPHERE around the reactor.

yeah, but dont forget the protection cover that every reactor must be coverd with. Its made of plumb and concrete, that would haver probably kept the radiation to very much lower levels. The bone heads didnt even have one !!!

Viktor you are right by saiyng that if you kept al the major components appart the incedentlevel wouldt be low,butt whe all know that this type of reactor had designfailures and it,s was simpel a matter of time that something would happen!!!Even if you kept the major components appart the reactor would overheated and lid would come off anyway!!!

I worked at a Nuke in the Northeast,in Connecticut. The one thing I'm noticing, they have all the major components in 1 building. In the U.S. everything is separate. The Turbine, ESF, Reactor Building, Intake and Discharge are all in different buildings. I think that's why TMI wasn't a MAJOR disaster, and Chernobyl was. I realize there were other circumstances involved,and Chernobyl was one mistake after another,but I truly believe separating all the major components has kept the incident level in the U.S. down.

parosbrosnye pipes - the same as number 4 pipes:
par = steam
sbros = let off / take off
