Little Sunfish Finds Shards of Reactor Fuel at Fukushima Unit 3

First, please see my previous post on Fukushima Daiichi's Unit 3's reactor fuel:
How Much Fuel Was in Fukushima Unit 3's Reactor?

Where is the fuel from Fukushima Unit 3 Reactor 
Second, please take a look at a video of Unit 3 published by the Asahi Shimbun showing some fuel found by the Little Sunfish robot http://www.asahi.com/ajw/articles/AJ201707250039.html

The robot is approximately the size of a loaf of bread. It has found some damaged fuel in reactor 3's outer containment, which is flooded with continuous injections to keep fuel cool.

At 4 seconds into the video we can see some damaged fuel and what looks like disturbance in the water. Can anyone decipher what is causing the disturbance?

Is it merely a reflection or is the broken fuel causing the disturbance?

Thanks for your thoughts!

Strangeness at Fukushima Daiichi

It has been raining at Fukushima. The hot fuel and the precipitation appear to be producing large amounts of steam but the steam production appears EPISODIC rather than continuous

Here are screenshots from the last two days with the high strangeness beginning this morning. TEPCO has most of the lights at the site OFF as you can see in the attached pdf of screenshots


Looking at these images, you might wonder whether the "emissions" are merely fog. I sincerely hope that I'm wrong and what I've documented here is merely fog for if I'm correct in my interpretation conditions have deteriorated suddenly.

Please see my posts over the last week for more discussion on this point.
