TOKYO - The temperature of a reactor at Japan's stricken Fukushima Daiichi nuclear plant has soared and remained mysteriously high Monday, despite more water being pumped through it.

The facility's No.2 reactor had reached 164 degrees Fahrenheit (73.3 degrees Celsius) by Monday morning, after sitting at 113 degrees Fahrenheit (45 degrees Celsius) on Jan. 27, broadcaster NHK reported.

That was despite Tokyo Electric Power Company (TEPCO) officials pumping 9.6 tonnes (10.6 tons) of water through the reactor each hour -- about 10 percent more than before.

Good comparison, finance and Fukushima.

Unknown factors, unintended consequences, and that oh-so-hopeful "illusion of Control"...

Pumping more water through the system and the on-going decay of radioisotopes yet the water temperature increases? Heat has to come from somewhere. More exothermic reaction with concrete? Thermo-couple instrument damage? Increased pressure in the reactor system? 164 DEGF is still way below boiling point at sea-level atmospheric pressure. The story does not make sense. Something is getting lost in the translation from Japanese to English.

Kevmo, you might want to follow this particular story. Has a familiar theme eh!

Maybe we are dealing with some previously undisclosed LENR processes involving some of the common radionuclides produced in this sort of reactor.

I say "undisclosed" because it's not believable that as long as the hot fission reactors have been belching out their share of radioactive wastes that the physicists presiding over that branch of science missed something like the unexpected production of heat!

Heat going up around a damaged nuclear reactor? That’s hardly mysterious.

The increased heat was coincident with a 10% increase in coolant water flow.

That's mysterious. Frightening in fact. Water is supposed to cool them down!

Does anyone have any reliable 'real' data about how much actual radiation the mainland US received from the Japanese nuclear disaster? There were some preliminary reports about radiation received on the West Coast, but then the whole issue just fell off the radar - as near as I can tell. Any people in the industry care to comment on this?

I came across some story speculating that recriticality is in progress.

Gee, imagine that. In other news, the economy is making great strides and the government is creating jobs.

I was watching a site for months that supposedly checked radiation levels around the US and Japan and you know what? The minute to minute reports showed zilch, nada, nothing, absolutely no rise anywhere...

The did find elevated levels in things like Milk. Even on the east coast. There was also a dramatic rise in birth defects on the west coast.

One of the things that will not show up with radiation detectors are the presence of just a few hot particles in the air. If you breath in one then it gets stuck in you, and exposes you for the long run. It was claimed that these had been found in various air filters here in the US.

Supposedly they changed the plumbing. The geniuses did not realize what cold winter weather would due to plumbing around their "cold shutdown" reactors. Numerous leaks and breaks due to plumbing problems caused them to install a new water injection plumbing route into #2. They believe that was the cause, at least that is what they thought, until they noticed that more water did not solve the problem. At any rate, this is TEPCO/Japan. The same organization that told the Japanese people they were winning WWII, at least up until those two bright flashes occurred. When TEPCO tells you to start worrying about #2, historically it means they are trying to misdirect your attention away from a greater problem.

That is but one possibility. There are unfortunately numerous others. From recent Bloomberg Article concerning temperature increase in #2.

“It was too early to say the plant is safe in December. They declared cold shutdown even though nobody is sure about the location of melted fuel,” Tetsuo Ito, the head of the Atomic Energy Research Institute at Kinki University in western Japan. “A similar incident will probably occur again.”

Also, right after the recent incident with the strange arclights, flash and smoke/smog from #4, TEPCO dramatically increased the strength of the night time spotlight that interfers with the view of the plant. Hiding possible nighttime emissions or flares is the speculation. Here is the video as they increase or turned the night time light into the camera. Tonight the brightness seems to be in between the old intensity and the new brighter intensity. The light dramatically increased at 43 seconds last night. Note the strange flash at around 34 seconds.

Also, the JNN camera has not been visible for awhile. That can never be good news. Right now it is returning an error message.

There are some Japanese blogs by ex-Fukushima workers that have some rather horrid documented possibilities of what has been occurring. Difficult to read the Google English translation however.

It is clear by now that the Japanese authorities are trying to cover it up as much as possible. I gave up on those folks. The question is how other countries are reacting to this worsening crisis. Surely Russia and U.S. have means to find out what is going on. How do they feel about it now? What are their plans if Japanese let this thing blow over?

No way it can blow over. Just a matter of time now. Next big 6.0 near Fukushima drops the #4 SFP. There are also some criticallities coming and going and anyone of those can lead to big problems. We are getting some decent intel from a former US NRC Emergency Response member on some of the blog threads. Her screen name is PattieB. Apparently there are some buildings across from #3 and #4 that were damaged. Some may be storing materials just as dangerous as the reactor materials (rare gas treatment building). They were using carbon to filter nasties out of the exotic gases that were ejecting from the reactors. Apparently a lot of very nasty concentrated material is stored in these buildings. They are also still bleeding off gases apparently, that should only be there if a nuclear reactions were occurring. This video shows what they are hiding with the spotlight. Note the two small flames off to the right.

If you want to learn about that area of the plant, there is a link to the Japanese web page below along with a google translation link. Good stuff is way down into the page.

I think I had mistakes in picking a phrase. I should have said "blow up." I also fear that there are numerous ways for this to go wrong and become even a bigger disaster. I am sure those two nations are aware of this. Would they be resigned to sit around and do nothing even if Japanese continue to botch the operation? After all, if it gets worse, it would have alarming impact on both nations? Are they just crossing fingers and hoping for the best?

Do you know what their current thoughts are on this?

Sorry about that. Yes [blow over] means pass by without incident or notice. [Blow up] means major incident and major notice.

Right now with the yahoos running the US, Japan may be our best hope. Apparently Steven Chu was recommending that explosives be used to blow holes in the reactor early on so they could get more water into them. Trying to find that link right now. Will post it if I find it.

Actually it was reported in the Washington Post.

Messages show conflict within NRC after Japan’s earthquake and tsunami

The NRC e-mails reveal disagreement about how to advise the Japanese. The NRC staff chafed at some un­or­tho­dox advice coming from an ad hoc group of scientists assembled by Energy Secretary Steven Chu. Famed physicist Richard Garwin, one of Chu’s group, proposed setting off a controlled “shaped” explosion to break through the concrete shield around the primary steel containment structure to allow cooling water to be applied from the outside. One NRC scientist called the idea “madness.”

Another idea from the Chu group was to attempt a “junk shot” — a variation on what some engineers proposed to stop the oil spill in the Gulf of Mexico — to plug leaks of radioactive water from Fukushima’s nuclear reactors into the sea. When using a mixture of sawdust, newspapers and other junk failed, Japan’s Tepco ultimately used a compound known as liquid glass.

Apparently the last people we need helping on this situation right now are those tasked with the responsibility. Where is Red Adair when you need him ?

Try this URL for some good technical reporting: http://atomicpowerreview.blogspot.com/

“Tokyo Electric has been monitoring the rise of this single parameter for some time now. No other parameter changes of note have occurred. For example, gas sampling of the containment at 1F-2 has shown no alteration of note. Tokyo Electric has been adjusting injection flow rates at all three damaged reactors for some time now in order to optimize temperature control vs. buildup of contaminated water; TEPCO has also been making some alterations in systems involving injection water sources and backup pump availabilities. TEPCO’s opinion at the beginning of this trend was that one of its flow alterations (variance between feed ring flow rate, and core spray flow rate, as well as total overall flow rate) had caused some sort of flow rearrangement (this is only a paraphrase) which allowed an alteration of temperature at the one location.

“[blogger]’s first suspicion is a progressing failure of the single temperature instrument. Barring this, it is conceivable that some disarranged portion of the internal structure of the reactor itself may have moved, causing the difference in temperature indication. For example, if part of the core further collapsed against the lower RPV head, this could conceivably be possible - however unlikely it is. It is also conceivable that any volume of accumulated, solidified salt from the time period early in the accident during which salt water was being injected may have moved, causing a similar indicated event.

“Having said all of that, there is no indication at the moment that any sort of increased risk exists as to further core damage, release of material, or recriticality. Even though this last mentioned possibility is exceedingly remote, TEPCO has, on Feb. 7th, injected boron into 1F-2 reactor as a wholly precautionary measure... although [blogger points] out that at least once TEPCO has injected boric acid in an attempt to help cooling by dissolving perceived accumulated salt deposition.

“The second overall Fukushima Daiichi concern is just a repeat of an earlier one; there is a thought that 1F-4 is in danger of collapse. The spent fuel pool of this plant was supported by steel girders, during a large construction project post-accident by TEPCO, and that space surrounding the girders filled with concrete, so that the spent fuel pool is now resting on a giant steel reinforced concrete monolith. Further, TEPCO is using giant cranes to remove debris and structural material (and, thus, considerable mass) from the tops of the damaged reactor buildings at 1F-3 and 1F-4 so that the risk of any collapse is further reduced. This “fresh” risk is also thus not fresh at all; TEPCO has no present concerns about this eventuality.”

“... Tepco tried to improve cooling further by tuning the rates of water injection. On 2 February, feedwater injection was reduced by two cubic metres per hour and the core spray was stepped up by the same amount.

“Water injection from the dark blue feedwater line was reduced, while the light blue core spray was increased by the same amount

“After making this change, Tepco noted a tendency for increasing temperature at the bottom of the reactor vessel. Within a matter of hours the company decided to reverse the change and restore the previous injection rates, but the temperature continued to slowly rise.

“Two of the three temperature sensors at the bottom of the reactor vessel edged up by about 2ºC. The third, however, rose by around 20ºC to hit 72.2 degrees at 5.00am today. Tepco acted to stem this increase by injecting an extra cubic metre of water per hour through the feedwater line, and this stabilised the sensor at about 70ºC. It has since decreased to 68.5ºC, while the other two sensors were at a new low of around 41ºC.

“Tepco was able to discount recriticality as a potential cause of the temperature rise after conducting an analysis of charcoal filters in the containment gas control system. These showed very low traces of fission products that were below the threshold that would indicate criticality. Nevertheless Tepco this morning injected boric acid into the reactor vessel as a precaution and increased the core spray injection rate by three cubic metres per hour.

“The majorty of unit 2’s core is thought to have melted and slumped to the bottom of the reactor vessel, but its configuration there is unknown. What Tepco’s experience indicates is that one portion of the deformed core relies on a certain flow from the feedwater pipe for cooling. While the core spray complements feedwater input and was significant in the push to bring the temperature below 100ºC, the two are apparently not interchangeable for one specific area of unit 2’s core. Tepco has modified injection rates at all three of the melted Fukushima Daiichi reactors several times in the past without experiencing warming effects such as this.

“The current injection rates are 6.8 cubic metres per hour through the feedwater system, and 6.7 cubic metres per hour through the core spray. “

... now confirmed by TEPCO, who are now saying that the high-reading instrument near the bottom of the reactor vessel at their 1F-2 plant is likely failed. The detector has failed a resistance check performed by TEPCO, meaning that the indication is confirmed incorrect.

It is thus safe to disregard this one outlier in terms of temperature readings at 1F-2 ...
