Follow-up to: *NEW* Goddard's Journal: Did Fukushima Unit 3 Fuel Pool Explode? (VIDEO)

The most recent analysis by Goddard’s Journal indicates a steam explosion took place at Fukushima Daiichi Reactor No. 3.

In the days after March 11, the NRC discussed the possibility of steam explosion(s) at Fukushima.

NRC Chairman Jaczko on March 18, 2011: “[...] look and see if you can’t come up with a [...] worst-case that is physically possible [...] I have to believe that there is no possibility in a light-water reactor design to reject an entire core. I mean, that’s basically steam explosion; isn’t it?”

Here’s more from Goddard’s Journal on the steam explosion:

“Figure 4 Animation: model of the initial phase of explosion based on data in Figures 2 and 3. The water in our model is darkened by contamination from molten off-gassing fuel”:

“Figure 5 demonstrates the explosion-triggering mechanism, an ex-vessel steam explosion as described in Moriyama et al. wherein water has pooled at the bottom of the containment vessel below the reactor. Then molten fuel falling through a melt-through hole in the reactor’s bottom triggers a steam explosion as it strikes the water below the reactor”:
