A Look At The Power That Failed At Fukushima

UPDATE:  Some additional images and diagrams found by Peter Melzer in the IAEA reports on Fukushima have been added below. These reference the incoming power system and failures at Fukushima Recent images taken by the media on their tour of Fukushima Daiichi turned up this image of the mangled incoming power line tower, a contributor to the station blackout. The next tower down the line can be seen to the right of the vent stack for units 5 & 6. The large high voltage towers to the left are the outgoing lines that send the generated power out to the grid. TEPCO had previously commented about soil liquifecation around at least one tower on this incoming power line system as a cause of power loss. As can be seen in the full … Read entire article »

620 mSv/h Found In Unit 3

TEPCO announced that they have found 620 mSv/h in unit 3 by robots. These levels are high enough to restrict entry. No reason for the extremely high readings was given. The high reading was near a containment lock but readings closer to the lock were 215 mSv/h. TEPCO has had ongoing problems with high levels in unit 3 but no specific reasons have been given. Map of the hot spot can be found on the last page of this TEPCO handout.

TEPCO Backpeddles On Criticality, Provides Questionable Reasons For Cause

TEPCO has changed their stance on the incidents recently at Fukushima Daiichi. Now they are claiming that the re-criticalities are actually spontaneous fissions. They state that the radiation levels seen have not increased enough to be from criticalities. While the concept of the problem being spontaneous fission is probable, TEPCO’s reason given is less so. “The amount of xenon-135 detected almost matched the amount that would have been produced if the radioactive curium in the fuel had undergone spontaneous fission.” This claim doesn’t seem likely or clear. TEPCO does not provide any detail on how they came to this conclusion or full disclosure of what was found in whatever testing was done. Some have questioned how TEPCO could make such an assertion. Others that if it was spontaneous  fission TEPCO would have known how to … Read entire article »

TEPCO And Contractors Fail To Pay Some Workers Proper Danger Pay

TEPCO and the contractors working at the plant have not been paying some workers the proper danger pay. These workers are doing their work in shelter buildings that are the same distance from the reactors as other areas designated as radiation zones. Due to the way labor laws are written it is not clear who or how these additional payments should be administered. Currently TEPCO is blaming the contractors and the contractors blaming TEPCO for who should determine the danger level. Meanwhile workers again lose out while the work situation at the plant goes on without proper oversight. This is just another work related problem at the plant, we have been reporting for months on everything from forcing workers to pay for lunch to problems with contracts and serious preventable safety … Read entire article »

Fukushima Unit 2 Xenon Found Indicating New Fission

NHK is reporting that Xenon and other substances are being detected at unit 2 indicating some amount of fission is going on. TEPCO claims the levels are low and they think that the fuel has not begun to re-melt. TEPCO began injecting boron to try to combat this. Unit 2 has lost pressure the last 4 days, temps have been steady with a slight rise. As seen in our live Fukushima Daiichi reactor data graphs. UPDATE:  There was a 5.6 degree temp increase in the RPV support skirt at unit 2 as of 10am JST UPDATE: TEPCO is now telling the media there have been no pressure or temperature changes at unit 2 – Maybe they need to look at their own data??

Unit 4 Still Poses Considerable Risk, Expert Calls For Independent Safety Inspection

A Canadian nuclear expert is calling for an independent review of unit 4 at Fukushima Daiichi where inspectors from outside Japan would do a safety analysis. He cites a similar process used in Canada to have US experts do an independent review of facilities to ensure no bias is involved. Currently the safety of unit 4 relies on promises from TEPCO that all is well. A collapse of the fuel pool or damage to the pool causing it to no longer hold water could quickly escalate into a major nationwide disaster. A NES report said that it would only take 2.3 hours for the pool to begin discharging substances if cooling was knocked out. TEPCO initially claimed there were no structural concerns with the heavily damaged building and fuel pool. NES … Read entire article »

TEPCO Confirms Steam Leaking Out Of Ground

TEPCO has admitted to the issue of steam leaking out of the ground around Unit 1. Water in the basement of the building was cited as the source of the steam. Extremely high radiation levels were also reported including a 5 sV reading on the 2nd floor of unit 1 in August. Readings over 4 sV were also found at unit 1 previously. There has been considerable speculation that the melted fuel has escaped the containment structure. These concerns have been backed up by various high radiation readings in the suppression chamber of unit 1. These readings also spike after each earthquake at the plant.

TEPCO Maintenance, Repairs With Duct Tape, Bailing Wire And More Orphaned Shoes

This TEPCO photograph of the pedestal area of unit 5 at Fukushima Daiichii. Unit 5 is the same design as units 1-4 and was built last of the BWR units at Fukushima Daiichi. The photograph is interesting in that it shows a rarely photographed area below the reactor vessel. This area is likely heavily damaged in units 1-3 as the fuel melted out of the reactor vessels. The equipment seen within the pedestal is the underside of the control rod systems. Some repairs have been made. One section of pipe is patched with a piece of plastic sheeting and duct tape. Another with some sort of patch and some sort of clear plastic film or tape. The patched section is then supported with wire. The systems inside the pedestal are the … Read entire article »

New Images And Video Inside Units 2 And 3

TEPCO released two crane videos. One viewing in the hole of unit 2 and the other some views of the top of unit 3. The images of unit 3 show what looks like at least a portion of the reactor well concrete plug still in place adjacent to the equipment pool. There is also a rust colored stain on the concrete where a steam path has been. We have found rust stained areas in other places where highly radioactive steam or water are leaking in large quantities. Ian Goddard has an illustration showing that this may be due to cesium rather than iron oxide. Unit 2 images show the wall panel that blew out was a removable panel. The bracket appears to be what the wall panel connected to. There … Read entire article »

Nuclear Expert Warns Unit 1 Fuel May Be Out Of The Reactor Building

We documented in mid-August that the melted reactor fuel (corium) may have relocated and could be leaving the unit 1 reactor building. Now Hiroaki Koide of Kyoto University’s Research Reactor Institute also states this theory is the likely scenario at unit 1. “At the No. 1 reactor, there’s a chance that melted fuel has burned through the bottom of the pressure vessel, the containment vessel and the floor of the reactor building, and has sunk into the ground. From there, radioactive materials may be seeping into the ocean and groundwater.” Koide also expresses concerns about the ongoing watering tactic at units 2 and 3, that it could lead to steam explosions if the melted fuel reheats itself and moves into an area full of water. There is also the same risk if the fuel … Read entire article »

TEPCO To Begin Removing Debris From Unit 3 Deck

TEPCO will begin the process to remove debris from the top of unit 3. Since the work would expose workers to high levels of radiation the work will be done by remote control heavy equipment. A platform 8 meters wide by 30 meters tall will be used to access the deck. There is approximately 3500 cubic meters of debris on the deck that will be sorted by radiation level. The work at unit 3 will take until next summer. The debris removal is a significant event as it will finally allow a clear view of the reactor well. The condition of the various plugs and caps in the well will add important new information about  the events leading to the explosion at unit 3. By mid-September TEPCO plans to start similar … Read entire article »

Specialists Have New Theory On Fukushima Daiichi Meltdowns

Many thanks to Ob_Li for translating this for us!  The original website : http://news.tbs.co.jp/newseye/tbs_newseye4822557.html Nuclear energy specialists team analyzed Fukushima Daiichi Nuclear Power Plant data and put together their opinions. It said “Although tsunami caused the power plants blackout, it wouldn’t have caused severe crisis like meltdown if it had been handled properly.” The massive tsunami attacked Fukushima Daiichi Nuclear Power Plant. #1 reactor completely lost the AC source. In the crisis like that, the isolation  condenser, aka IC, which enables to cool off steam throughout the coolant inside of the tank and changes it into water, then put the water back into the reactor had to be utilized.

TEPCO Wants To Restart Units 5 & 6 At Fukushima Daiichi

This is no joke but it sure sounds like one. TEPCO has been quietly planning to restart units 5 & 6 at the destroyed Fukushima Daiichi nuclear power plant. As some of the workers pointed out, all of the support services and administration facilities for those reactors are destroyed. In TEPCO’s current working plans has been the repair and improvement to the intake system and sea walls at unit 5 and 6. There are multiple activities that serve no purpose other than towards restarting these two reactors. The units were in maintenance mode when the earthquake hit and they sit slightly higher than units 1-4. This saved them from the total destruction seen at units 1-4.

New 57 (Sv/h) Radiation Increase In Unit 1 After Aug 17 Quake Near Fukushima Daiichi

A new significant earthquake ( 6.2) occurred at Fukushima Daiichi on August 17th . In our previous report we explained the connection between the recent 6.0+ earth quakes and changes at the plant. The quakes caused changes in the pressure, temperature and radiation levels in the reactors indicating relocation of the melted fuel and concerns about building integrity. After the most recent quake on the 17th,  the radiation readings at the drywell “b” sensor spiked from 359 (Sv/h) on August 15th to 416 (Sv/h). This was a 57 (Sv/h) jump in radiation levels in just over one day.  The drywell sensors are in the concrete containment bulb below the reactor pressure vessel.

Anomalies at Fukushima Daiichi Tied To Recent Quakes, Concerns About Fuel and Buildings

A series of significant anomalies were noticed in the TEPCO reactor data in recent weeks. When these anomalies were cross referenced against recent large quakes near the plant a concerning pattern appeared. Radiation, temperature and pressure readings show a disturbing trend that indicates that melted fuel may be relocating. This set of information shows that there are concerns about the integrity of the concrete buildings. With reports of steam coming out of cracks in the ground and high radiation levels being found outside the reactor buildings these could be indicators of such damage. fukuleaks.org/web members have plotted the data and provided technical analysis below.

Why “Cold Shutdown” Is A Myth And Going Home Unlikely

The Japanese government has been touting this “cold shutdown” myth extensively over the last week. As Ex-SKF put it, the “extend and pretend” strategy. The government seems to think it means under 95 degrees celsius and atmospheric pressure for the coolant system. The Wikipedia entry goes on to include having no fuel movement and or control systems maintenance in progress. From wiki: The shutdown margin is defined in terms of reactivity, Shutdown margin can refer either to the margin by which the reactor is subcritical when all control rods are inserted   The reactor vessels are breached, unit 3′s containment has been breached since March 21st. #2′s containment has a known hole in it and #1′s leaking like a sieve through the basement.
