A fresh photo report from the Kursk Nuclear Power Plant.
Put that back up generator up high where water can’t reach it.
OMG another nuclear power plant! I can’t get enough
“Instructors act out the Fukushima scenario (the total loss of electricity) and cope with occurring problems.”
Oh great. Isn’t this what caused Chernobyl to explode?
They’re acting it out on a simulator, not on the real plant. They’re not likely to make that mistake.
Besides, Chernobyl was a totally different kind of accident, it wasn’t a loss of coolant or loss of power accident.
DOES THE OWN GROWN FISHES HAS 3 EYES LIKE THOSE FROM THE SIMPSONS LOL
a BIG thank you to the redaction to show us a real russian nuclear power plant
Very nice but as always I find those plants very scary
Chernobyl was a series of power spikes that killed the cooling system.
Thanks, jencha, for another fantastic nuclear power plant photo diary! Wish I could join you sometime.
Chernobyl have nothing to de with Fukushima. It was an experiment what they did in Chernobyl #4 unit. The idea was to test if the turbine residual movement can supply enough power in order to turning on the coolant pumps after a general electricity failure. It was not a dangerous experiment itself (it had been completed a couple of times before in other plants, with negative result), but when trying to simulate the conditions for the experiment the operators made a mistake, and let the reactor power slip to only 1% (the specifications set the minimun working power at 30-35%). That didn’t cause the accident, but create iodine and other isotopes in the core, intoxicating the reaction. At that point, they should had stop the whole thing, but there’s a lot of pressure, and probably they didn´t know about the intoxicating iodine in the core (they were not preapred for that situation, as it was very unusual). After that, when operators were trying to increase power, only can push it up to 7%, due to the intoxication. At that point began the really critic mistakes: they disconnected several emergency systems, including the main computer, because they noticed that the computer correctly was about to shut down the reactor. They have big pressure to put the reactor at normal speed to supply an energy demand from Kiev. At the end, when the whole thing had gone wild, the decided to insert the control rods to stop the whole thing (the pressed the “red button”), but it was too late. In fact, pressing the button made the things going wilder, because when the control graphite rods were inserted, due to the abnormal state of the core, instead of slow down it, it caused a super power peak, and then the first explosion happened. The coolant was too hot, and the pipes cannot resist the steam pressure. It is stimated that the core reached x10.000 – x30.000 it’s nominal power. Adter that, the whole core colapses and explodes, throwing to the exterior of the plant entire chunks of radioactive fuel bars and graphite bars…
I was reading about the device they used for replacing the fuel assemblies and was wondering how it can remove the assemblies from a pressurized vessel without shutting the reactor down. That is a very impressive looking device.
RBMK is Channel-type Reactor. That means ~1.5 thousand of pressured water pipes instead of one vessel. Fuel rods are located between water pipes and can be changed one by one without shutting down.
