WEBCAM March 2018
03-21  The tepcam 1 view changed yesterday; more zoomed in and aimed at a slightly lower height.  The view was crisp like the lens was clean.  Kinda makes me wonder if we have a new camera.  Only a little less sky but a spark count finds very few sparks.  I hadn't noticed many while watching, it was only seeing the cam4 spark that made me go looking into the recordings and count cam1 sparks.  I did notice a lot of missing time; the clock jerking past several seconds at a time.

One hour scanned; only 6 cam1 sparks and 1 distortion; one spark on cam4.

Majia: It appears that TEPCO may have replaced the cam on units 1 and 2 because the cam view is sharper and the perspective has changed (greater focus in on buildings) http://www.majiasblog.blogspot.com.uy/20...s-1-2.html
just pm me if needed.
The time difference between the two tepcams is still 42 seconds on my equipment and connection; watching them side by side.  Events I catch happening on both cameras at the same time, have that 42 second difference; cam4 displaying later than cam1.  I looked because I thought a new camera might have a different time set.  If it is the same old camera it got some maintenance and a new focus.  The emissions Majia notices sometimes on cam1 will be off screen and not as visible now.  We'll only see it on cam4 when it gets really bad.  I've been seeing 10 seconds or more between sparks on cam1 which is down from the every 3 to 5 second range when activity was high.  There is less dark background for them to shine with the new focus and that might reduce counts.  During the day, I'm seeing better views of the tools and loads the large remote crane is using at r1.

How to Spot a Nuclear Bomb Program? Look for Ghostly Particles
Quote:The vast majority of antineutrinos from the Hartlepool reactor would pass unimpeded through the new detector, but calculations by the scientists indicate that two to four a day would collide with a hydrogen nucleus — a proton — in a water molecule.

When this collision occurs, the proton transforms into a neutron and ejects a positron, the antimatter version of an electron. Because the positron moves so quickly through the water, it emits the optical equivalent of a sonic boom, called Cherenkov radiation. (Watchman is a shortening of Water Cherenkov Monitor of Antineutrinos.)

The sparks I see on the tepcams are Cherenkov radiation.  The tepcams are useful as radiation detectors with the Cherenkov sparks blinking in the night.  I think that Tepco purposely zoomed the camera tighter so we won't see as much in the way of emissions on cam1.  They haven't be able to stop the radiation still leaking out.  Opening r1 was the beginning of the increase of sparks I notice on cam1.  Remote crane work continues over r1, vacuuming, spraying, containers moving in and out.  Haven't seen much happening over r2 since they cleaned the roof.  When work to remove debris from r3's sfp occurred the sparking increased.  Covering r3 with the fuel removal roof hasn't stopped the sparks.  Suspected emissions from the CSFP always caused a spark increase.  Now that the spent fuel has had years to cool we don't see as much fogging or long lasting webs.  The sparks don't blink as much as they did in the early days but spark flurries still erupt regularly.

17 sparks an hour.  Didn't notice any distortions from dusk to 8pm. The spark flurries still occurring; radiation still drifting in the air over Daiichi. Here's a daytime view of r1 with one of the remote crane loads and a couple sparks.  You might notice a light in r1 that was blinking.  It's off in the second spark pic and on in the other two.  The r1 light has a reddish hue.

Covering r3 with the fuel removal roof hasn't stopped the sparks.  Suspected emissions from the CSFP always caused a spark increase. 

Thinking back on all the events we've witnessed and am considering the ground to be a likely source of rad emissions besides the SFP. Recall the steaming fissures in the first months or year after? With all the earthquakes since and torrential rains, there's probably been substantial changes in the layers of earth under and around the reactors. If that's the case, yeah, a roof over the reactor isn't going to reduce much.

Work on the ground might make a difference. Make it impermeable. If possible.
just pm me if needed.
Most of the ground at the plant was covered with concrete just to cut the rads.  Tepco has ground monitors they say indicates safe levels that never vary.  The tepcams are a couple stories above the ground so I think they give a better air reading.  Several likely sources to choose from, and my guess is they all add together.  Sometimes one source might get worse but unless I can see something on the cams or read about some problem it's hard to pinpoint which one.  When they closed up r4 and finished the r4 sfp removal work, the CSFP emissions went down and sparks on cam4 really diminished, cam4 sparks are rare now.  Cleaning the roof of r2 may have helped some.  Tepco says the north end is still much more dangerous than the south end and the camera sparking rates agrees with that assessment.

Wonder if the concrete was modified for greater lasting power - over time, esp. with earthquakes, it will degrade and crack again. Are those monitors the ones they put lead bases under? I think you are are correct - it's a series of different sources that perpetuate the emissions and sparks. It is curious that the data from the monitors rarely changes. Wonder if that holds true when there are earthquakes nearby.
just pm me if needed.
Fantastic picture Code.  It shows much more ionized air rising above the plant compared to what Tepco may be measuring at ground level.  Let's say r1 was a stove top with a pan on it.  Placing a thermometer over the top of the pan would be much hotter than a thermometer sitting by the pan.  Daiichi would be three pans and only number two has a lid on it.  Of course, Tepco would be more concerned with the radiation at ground level affecting work than any radiation plume rising above, contaminating the air that blows out to sea.
