WEBCAM November 2018
#1
Post webcam observations for November here.  Observations should start with a date and ‘jst’ time (Japan Standard Time) and camera(s).  Describe as best as possible what you see.  Contribute data such as weather conditions, work activities, TEPCO or local news reports, radiation readings, earthquake activity, or any information that documents events occurring at Daiichi.  Comments and analysis welcome.  Help keep an eye on TEPCO's disaster site.

The month has started out pretty routine on the tepcams.  Remote cranes move around loads on work days.  I see the occasional spark on cam1 at night.  

HHD asked about the TBS-JNN cam in this thread and I found an old test recording.  See the TBS-JNN thread.

The panels came down a few days prior to the Oct. 05 event. Increased camera smashing Oct/Nov.. EQ Nov.. JNN cam last seen sometime prior to Dec 03, 2016...

The Webcam Threads are helpful and informative...

I bet TEPCO never thought camera smashing would tell us so much about the radiation levels on-site.  Thinking back on it, your sighting of unusual activity must be what prompted me to start recording TBS-JNN.  It sure looked like something had happened.  Something big enough to send sparks and smoke all the way off site to the TBS-JNN camera.  Glad to add your observations to the documentation.  The decommissioning work is a dangerous endeavor; another disaster waiting to happen.

Agreed. You went through the trouble of setting up recording hardware for JNN, then it was gone...

Trying to place those 5 tanks visible on JNN. Looking at site pics, I know they are above reactor site, but unable to find overhead shot with them. Many tanks added since... The fire thing was visible between the tanks two and three from the left. Thinking it happened @ reactor 3 rubble, as that can barely be seen between those two tanks.  Knowledge of their location would simply help me to understand the angle of the view and better determine the location of the event. As it stands, as I said, thinking it was r3 and not within the holding tanks themselves, as it initially appeared.

If it was on site (ocean-level), it had to be huge...

Seems if anyone had the footage, it would be califnative?

Onwards.

Here's the thing HHD, I watched the panels come off and the uptick in sparks on cam1.  When the CSFP sputters I find cam4 sparks.  An event at r3 would have shown in the middle of cam4.  Smoke on the left edge of cam4 is more of a CSFP area steam up.  None of that has caused TBS-JNN to spark up like it did.  Maybe this will help.  There was smoke on TBS I captured in 2014.  I placed it over the 10-05 grab to help approximate locations. Is this close to where you saw fire and steam?

True... U3 event would have been visible... Perhaps that is one of the reasons I presumed initially it had to be beyond the relatively small puff of smoke we can see on the left on Tepcam u4 Oct 05. 

Yes...Between second and third tank, from the left. Almost level with the top of the tanks. Bright and condensed. It was behind the tanks but bright enough to blur the two edges of the tanks in its fury. 

Could a nuclear reaction result in a local firework display of spectrum? Like a massive weld? If it was a fire, it was extremely hot, large and condensed, put out within minutes and had what looked like more steam than smoke, iirc..

Would have been a long reaction, or a short, intense fire...

Do the watertanks pose any risks of such events?

What is housed just below the cliff embankment?

Notice the delay in cranework and lack of visible workers following the event.

At first, not much.  Classic shot of steam coming out of the r3 rubble pile.  This also shows the steam coming out of r2's seaside vent.  On cam1 we would just see smoke coming out of the top of r2.  Cryptome aerial-2011-3-30-0-50-45
   

A grab from this Cryptome picture shows the embankment drop a little better from the different angle.    

A recent view of that area from NHK World http://caferadlab.com/thread-1037-post-4...ml#pid4681

The embankment between the water tanks and reactor buildings gets filled in with trimmed trees and rubble piles.  Maybe it was debris burning but that doesn't fit with your description.  What you describe sounds a lot like AirSepTech's description of cryogenic gas releases.  A cryo tank truck parked on the road while they're constructing the ice wall might have been vented. I was never able to figure out what the 2014 smoke was from.  One possibility for your 2016 event sighting might be radioactive pieces in the rubble pile coming together, getting critical and sputtering until they were pulled apart.  That would at least explain the radioactivity causing the sparking on TBS-JNN for the next few evenings.

11-15 There wasn't much new to report. Some sparks blinking in the night. It was busy with the cranes moving large objects the last couple work days. I didn't notice that cam4 was frozen at about 9:30 until later that afternoon. Had trouble getting the browser to load the Tepco site with an unable to connect message, so I decided to stop and transfer some recording files. The computer had plenty of room yet and checked out clean with rkill. I got it up again shortly after 15:00 and the browser loaded cam4. Was noticing a band of haze in the afternoon light and watching for a freeze up. The time has changed from a 40 second difference between cam4 and cam1 to some 3 or 4 seconds. Wondering if cam4 had some maintenance done. The camera times are as close as I've seen them before watching the two of them side by side. There's that strange band of hazy blue I hadn't noticed before.
