It was also appeared in the Cessna 172N.
My favorite GA plane ever was a Cardinal RG. Smoothe, spacious, kinda nice layout. A bit underpowered compared to a 205 , but still very nice to fly.
Worst GA plane ever was the Traumahawk.
Water to ice however does not generate a 1,600 times increase in volume like water to steam does.
I'm thinking that I read uranium oxide's boiling point was around that, but that the melting point was only about 2,800 C? No problem for a plasma torch though. :)
Richard T. Lahey Jr., who was General Electric’s chief of safety research for boiling-water reactors when the company installed them at the Fukushima Daiichi plant, said that as seawater was pumped into the reactors and boiled away, it left more and more salt behind.That's unbelievable. 50 tons of salt?!?!? I mean, the insides of those reactors are big, but are they that big they can hold all that in addition to everything else in there?? Those numbers are an order of magnitude bigger than what I expected.He estimates that 57,000 pounds of salt have accumulated in Reactor No. 1 and 99,000 pounds apiece in Reactors No. 2 and 3, which are larger.
The big question is how much of that salt is still mixed with water and how much now forms a crust on the uranium fuel rods.
That gives you a good picture of the torus. The picture of the plant I posted has a suppression pool rather than a torus.
Good candidate for sure.
I like the 172/177 Cessna RGs too. A little underpowered as you say, but very efficient, have a long range, and relatively fast with the gear folded.

Neutron beam observed 13 times at crippled Fukushima nuke plant
I know nothing about Nuclear power .. but this can’t be good
Blue glow? Cherenkov radiation?
That doesn’t surprise me. They’re literally dumping tons of water into the spent fuel pool area with helicopters and the deck guns on fire engines. Some of it has to wash out of the building given the damage. However, water is still not escaping from the containment.
Not sure, it looked bright and in upper spectrum of white. Sorta like an arc from a welder but steady. No idea what size it was. You could see it inside the framework of the building and the translator/narrator pointed it out. It’s in one of the helicopter flyover videos. I’ve looked at a number of them on Youtube but haven’t found it.
That was great...!
My understanding of Neutrons is limited but i understand the cause of beam like behaviour.
A guy on another forum has a still of that but I can't get a hold of him now.
NeutonBeam?They should be burying that sucker as we speak.
If there is Cherenkov radiation ( blue glow) , its freaking too late. They will have to get out of Dodge.Why don’t they just bury the sucker? Thats the question the whole world is asking.They can go back in to clean up in 100 years or so.
The Japanese have a purity streak that may get massive numbers of people killed.They do not want to have to make Sendai into a no mans land for 5 generations, but they have to face the fact that it has to be done.Thats the real problem.
Is a "neutron beam" even visible?
Hence, I see little potential hazard here except for perhaps children. In their case, iodine pills, avoiding milk, and drinking bottled water should be sufficient precaution.
Steel looses its strength as temperatures increase.
In order to be 662 F and have water in liquid form the pressure inside has to be quite high. When you consider the size of the containment vessel and the pressure there are tremendous forces at work. It isn’t hard to believe the combination of those forces and temperatures beyond the design limits could cause a breach.
A last resort for cooling is the nearby seawater. Why do you think they locate these type of reactors near a body of water?
Venting contaminated steam or discharging contaminated seawater, pick your poison.
Either you cool with seawater thereby contaminating, it in this case, and discharging it back into the open ocean (tons and tons of it) or you let the reactors meltdown then have to cool it down anyway and spew contamination (radioactive) into the open air and sea.
As of March 16th...Units 1 and 2: TEPCO has released estimates of the levels of core damage at these two reactors: 70% damage at Unit 1 and 33% at Unit 2...Noted at...http://mitnse.com/page/2/
Recently March 22nd...”Tokyo Electric Power Company released the results of a half-litre sample of water taken 100 metres south of the discharge channel from damaged units 1 to 4.
Testing for a range of radionuclides showed amounts below regulatory limits for cobalt-58, iodine-132 and cesium-136. Detections were far above limits, however, for cesium-137, cesium-134 and iodine-131...
...Iodine-131 has a half-life of eight days, so its potential danger reduces relatively quickly. Caesium-137 has a half life of 30 years, whereas the other isotope, caesium-134, has a half-life of two years. Additional monitoring at eight locations is to be carried out by the Japan Agency for Marine-Earth Science and Technology in conjunction with the Japan Atomic Energy Agency. Results from this are expected on 24 March.” Again this from the MIT site...http://mitnse.com/
It’s not clear to me how the spent fuel ponds are doing but anything using saltwater is toast (never to be used again). The MIT site also says units 5&6 are pumping saltwater through them to remove residual heat. I take that to mean via a heat exchange(r) but saltwater none the less but probably not contaminated.
Thinking about your questions makes me realize something that I have been musing in my mind for some days now ...there must be A WHOLE LOT that we have no idea about, and the situation in Japan is not as bad as those saying meltdown claim, but at the same time it is nowhere as ‘ok’ as those FReepers calling folk Chicken Littles also claim it is. I believe there is a lot of information that is not being released, and it is only when things go a certain direction (e.g. a ‘success’ story yesterday today becoming one where workers get evacuated) that some news comes out because it cannot be kept down. I am not talking conspiracy or anything like that, simply stating that while it is not a Chernobyl it is also not ‘nothing to be concerned about’ or a ‘radiation is good for you’ scenario.
