08-15 025102  Cali finds a double - green meanie.  My recording only had 6 frames of 025102 and I missed it.  Lost four frames of time in the recording and missed a nice double.  Found a single green at 025103.

08-15 While I was just glancing at the monitors after dusk, I didn't notice any sparks until the burst started.  It was like a door opened and the crowd poured out.  Started scanning at 19:55.

08-17 Major Fuku fog overnight.  Scanned both tepcams from 21:30 to 22:30.  The sparks started on cam4 as the fog thickened and then developed on cam1 as the cloud drifted north.  It looks like CSFP vapor releases with a couple sparks on the south camera and then a burst on the north camera.

Mini reactor- Sparks, just the same. Interesting comments…

Hillbilly, you ol' Hound Dog, this video identifies the blue glow as Cherenkov radiation and the sparks as gamma. One comment called out N-16; a neutron activated product with a 7 second half-life as the source of gamma; 10 mR/hr next to the pool. The tepcams are some distance from the reactors and the common pool so I think it must be other gamma sources at Dai-ichi. I still think the sparks indicate recent on-going fission. The other day I caught a couple cam4 sparks with some Fuku fog. Something is causing a radioactive cloud to expand and extend down to the south camera. What goes on at the common pool that we don't get a direct camera view of that area? It's a shame that tepco has reduced the cameras and views that we have access to, I really miss the chatter the webcam forum used to get. ENENews is suffering the same slowdown of news as tepco shoves Fukushima into the background. Lots of problems tepco doesn’t want to talk about; dumping tons of tritium to the ocean; hot particles all over Japan; what’s left in r3 to recover; will there be room in the common pool for another tank of spent fuel; why do the cameras still spark so much? The nuclear industry is in retreat but they have so many messes lying around, keep hounding them, Hillbilly.

Had to repost the video Hillbilly found.  A controlled, water shielded reactor was still releasing nuclear elements emitting Gamma radiation measured next to the pool and showing as the Cherenkov radiation sparks detected by the camera sensor.  A 10 mR/hr reading during a small spark burst on the video to roughly calibrate the Gamma of the spark bursts I still find on the tepcams.  The tepcams are important as uncensored gamma detectors even if the views don't always show much.  Maybe tepco hopes that no one is watching anymore.  

Was thinking about how empty R4 is now, maybe a cores worth left in the SFP.  The R4 extension work light is the first one to come on every night.  The pool might be a testing bed for their robots to remove nuclear debris.  Nah, tepco said it was empty and doesn't talk about R4 much.  

08-23 am watched some remote crane activity over r1 and some of the small ones in the foreground of cam4.  I've got some spark counts from 8-20 I'll get posted later.

08-20 Spark report.  Scanned both tepcams from 23:00 to 01:00.  I didn't find any sparks on cam4 in the two hours.  I had noted a couple I thought might have been sparks.  One turned out to be a long pause of missing time and the other was a distortion.  I noticed a lot of missing time pauses on the cam4 recording, maybe a performance issue but some nights seem worse than others.  The cam1 recorder is a faster computer and I still get missing time on it.  However imperfect my attempts at documenting the tepcams are I'm still finding rapid spark bursts in the night.  

The first hour started fairly slow, 15 minutes between sparks the first half hour.  The distortions hit the camera and the sparks took off.

A ten minute pause and another burst.  Nineteen sparks an hour indicates a lot of hot particles passing by the camera sensor.  I don't think there's any dramatic lowering of radiation at the site.  Tepco may have improved some locations but when I look, I'm seeing higher spark counts on the tepcams than last year.   Looked back at last August webcam and found counts between 12 to 15.

Spark reports wouldn't be complete without a few pictures.  I found a nice purple meanie.

08-24 While I was getting the 8-20 spark count posted I happened to notice two blips on cam4 about fifteen minutes apart.  That’s a small burst for cam4, had to check it out and found three sparks.

08-24 Added a couple of fancy sparks I spotted to the collection.  Now that tepco is back to work will they get the spark counts down?

08-28 Saw a bright light over the csfp.  The light went off at 21:36.  Probably a work light when it repeated the next night 08-29.  I went looking for spark bursts but only found a slow steady stream anywhere from 4 to 10 minutes apart.  When tepco returned to work the first thing they did was send crane tools into r1.  Were the spark bursts from r1 or some other activity tepco performed during the break?  The spark bursts were somewhat alarming at 19 per hour.  Here's pics of the work light.

08-30 early am, the new fuel removal crane came out of its shell today and moved back to the west end of r3.  They might be using it to move ring segments into place.  We’ll see if another ring segment gets added and towed into place on the sea side.  I saw workers moving across the top of r3 before they moved the frame but they don’t show clearly in the gray dawn.  Here’s some pics of the work this morning.
