Reply #348: Thanks I do like the chart

Thanks, Xxxxx, I do like that chart. It is interesting that the Unit they suspect of a leaking RX vessel and containment (where all the water may be coming from), U2, is not the Unit with most core damage or most extensive damage to building from H2 explosions. It makes one wonder what happened to U2. It is good to see that Units 5,6 seem to not have suffered much damage. I am glad to hear that AC power was restored and fuel pool cooling is on. Great! Back to U1, though... it is not good that the temperature is not declining much. The chart is pretty vague about what they are doing to control pressure in the RX vessels. There is a reference to a low pressure being created in vessels (condensing steam can do that). The discussion about the RX vessels 2 and 3 losing their leak tightness because of low pressure? Low pressure? Vacuum? I am not sure what they are talking about and how it could cause a lack of leak tightness. Since they think there are no cracks or holes in them, I guess they think some seals or valve packings may have failed if exposed to vacuum. There is a big leak, so maybe in the control rod drives and-or nuclear radiation monitors penetrating the bottom of the vessel. U4 fuel pool is a problem. The hot core from the vessel is in the pool. That is why its RX was badly destroyed from hydrogen. There is a lot of damaged fuel in that pool. I would fear that the leaking water might be coming from it. A water sample from this pool would be a good source of info.
