It does abruptly end and smoke does not do that. Too bad we don’t have a movie of this. Assuming this is not a still shot taken right after event happened then it seems to be steam. It reminds me of vapor above a warm body of water in cold weather but much thicker.

I thought that it also had MOX in the SFP, but do not know, of course. What is your opinion? Smoke or steam?

Oh swell. Unit 3 has MOX. Does the SFP have MOX, I thought not.

The below is a photo that the press calls a fire in U3 during the event.

When I took a second look, I wondered what happened to the “smoke”. The plume sort of ends, not dissipate like thick smoke usually does. This looks much more like a steam plume during cold weather (remember it is still cold there as they had snow)(at least to my experience, but will defer to Mark as concerning smoke behavior).

This may really be the U3 SFP boiloff.

This amount of steam seems a lot for decay heat.

This may really be nuclear heat from an undesired criticality.
