I have been reading technical reports and whatnot about Chernobyl for some time, and I'm feeling that they-or their wording-is not quite letting me understand it. For lack of a better way to present my many questions, I am requesting an evaluation of one of my current understandings of the Chernobyl explosions; mainly if it is consistent with published research and what parts are and are not.
- 01:23:44-Power in a hotspot in the lower southeast quadrant of the reactor causes these fuel channels to explode.
- The channels are depressurized and the resulting boiling of water forms steam that is released into the empty space between the channels and the graphite. Aiding greatly is the positive void coefficient kicking in at the broken area of the channel.
- 01:23:46/7-This causes a lifting force on the reactor lid which lifts it up somewhat, jamming the control rods, tearing apart the remaining fuel channels (which are attached to it) releasing their steam in the same way as in #2.
- 01:23:46/7-The lid moves so high it floats above the reactor hall floor. The steam bursts through the gap thus formed. This is the first explosion
- With the steam gone, pressure in the reactor drops and the lid begins settling down. Meanwhile, the loss of water is allowing an outrageous power surge.
- 01:23:49/50-power is 300 gigawatts. A hydrogen or nuclear explosion blows the lid through the roof, and kills Valery Khodemchuk. This is the second explosion.
