TEPCO released a video of almost tranquil-looking Fukushima I Nuclear Power Plant. You mostly see the facilities related to the contaminated water treatment system, as the video is an accompaniment to the presentation that TEPCO did on the overview of the water treatment system.
The site looks clean enough, though it does have a look of a ghost town. You get to see some buildings and facilities up-close, including reactor buildings. Quite a desolation, on a bright sunny day.
After watching the video and thinking about a "localized" re-criticality (or nuclear fission sustained over certain period of time, as some "experts" insist on calling) that even TEPCO has admitted may have happened, and reading tweets and news articles to notice how the government experts are doing their utmost best to downplay the re-criticality event in Reactor 2, I have a sense of quiet, almost resigned, crisis coming.
Anyway, here's the presentation of the water treatment system by TEPCO. It is actually a pretty good overview of the entire process, though it took TEPCO 4 months to explain the system to the general public. (Wow it even has a voice over.)
