Pressure continues to rise at #1
If these graphs are trustworthy, then there are two still-developing situations, although both are moving slowly, and neither looks like an emergent problem in the short term. But in dealing with previously damaged systems, all bets are off.
The pressure in the core of Fukushima Daiichi number one continues to rise, while the drywell pressure falls. The rising pressure is disturbing even though it is just approaching 1,000 kPa, which is about ten atmospheres. We have seen these vessels performing well in excess of 6,000 kPa, and at the rate the pressure is rising, that would be weeks from now even if it continued in a linear fashion, which is unlikely. So as a raw amount of pressure, it is not alarming, but the fact that it … Continue reading
