From: Sandy Mc Lean
Date: 14 Mar 11 - 11:33 PM

I should stay out of this discussion but there are a few things that I will say. The disaster in Japan has torn at everyones heart in the last few days and I am no exception. The force of the tidal wave (yes,I know it has a different name now)was beyond belief! God only knows what the final count of those lost will be but it is going to be in the tens of thousands from direct effect of the quake alone. As for the power plants in question if there is an emission from radioactive debris like cesium many more lives could be lost spanning decades to come.
I am no scientist but I do not believe that it is possible to create any atomic blast from fuel grade enriched uranium melted down or otherwise. I say this because this grade of refinement of uranium is not pure enough to create an uncontrolled chain reaction like a bomb. In order for a reactor to attain fission many fine tolerances must be met and in order to create fission of uranium of less than about 85% U-235 neutron bullets must be slowed down in order to gain a collision with its neighbour atom. These requirements do not happen by chance but require intentional input.
That being said any chemical based explosion releasing debris into the air is no trivial concern! I do however believe that to run around like Chicken Little proclaiming an impossible situation is irresponsible.
I am at a bit of a loss to comprehend why Japan would ever allow a light water enriched grade reactor on its soil. The plutonium by-product has attraction for nations wanting that element for weapons but Japan has no nuclear weapon use or manufacturing ability.
The CANDU system mentioned earlier has less volatility because it uses natural uranium which requires no enriching centrifuge and can be quickly shut down by inserting dampening rods into the reactor core as well as by replacing the deuterium bath with light water. I believe that the system is fail-safed to do this automatically in an emergency. It is also my understanding that a large pool of light water sits above the reactor core ready to spill in in an emergency situation as well requiring no powered pumps.
Many things in nuclear physics are beyond my feeble comprehension but I do understand panic!

I just watched the explosion of the containment vessel fo #2 .
It was a TREMENDOUS BLAST sending steel concret and qoo tons of Plutonium and uranium 1000 feet into the air.

This was unlike all of the hydrogen gas pops.


Reactor 4 is on fire becasue the new rods to be instaled in dhutdown reactor 4 and the spenmt fuel rods are exposed to air and hundreds of tons of nuclear fuel is now on fire.

Every worst case meltdown scenario is now taking place

Short of a a fssion explosion this is a fission explosion in slow motion involving unimagined amounts of nuclear fuel.

There remains more reactors that are in the same shape that these 4 reactors were in 2 days ago.

There are virtually no more workers to do anything on site such as pour seawater and boron.

From here on out any workers who try to dump boron on the scene will do so at the cost of their lives within 30 days.

Nuclear industry spokespeople who have spun the wonderful safty backup plans and total impossibility of anything like Chernobyl should now shut the fuck up. That includes Glen Beck who said no one was ever hurt by the the private nuclear industry be it 3 mile Island or even Japan.

New update from NIRS:

"UPDATE 7:30 pm, Monday, March 14, 2011. Tokyo Electric Power is holding a press
conference at this hour. Video stream is at http://www.ustream.tv/channel/nhk-gtv2. NHK
TV reports that there has been an explosion at Unit 2 at Fukushima Daiichi. There is
speculation that this explosion has damaged the primary containment (inside the concrete
containment building, which is the secondary containment. Tepco is evacuating some non-
essential personnel from the reactor site. 2.5 meters of the core are currently uncovered by
water—which means it is almost certainly melting. Winds from the site are currently blowing
toward the North. "

The accident is now being characterized by MNBC nuclear spokespeople as worse than Three Mile Island, which was a partial meltdown of the core without a major release of radiation to the environment. Japanese plant workers are still onsite attempting to cool all three reactors with sea water. Non-essential utility staff have been evacuated.

Perhaps only a vlave has burst. They suspect that air from the containment vessel is coming out. They can not be sure about the bottom of the containment vessel but they mentioned that the vessel has lost its water.

100 tons of 95% uranium and 5% Plutonium shoudld not be allowed to collect into one giant ball.

Despite the danger boron and water should still be poured on this mess despite the risk of steam explosions and drastic radiation release. ITs better than the small chance of criticality growing into a runaway chain reaction. Yes I know they say this is impossible but at temps over 5000F we have no experiments to refer to.

Here's the latest update prepared by the Nuclear Information Resource Center:

UPDATE 12:30 pm, Monday, March 14, 2011. According to our colleagues in Japan, Tokyo
Electric Power states that Fukushima Daiichi-2 "has again lost its coolant (sea water was
pumped in but is dropping). They cannot ease the reactor pressure because the relief valve is stuck closed. Air dose rate on site (outside the reactor building) was 3,130 at around 9:30pm."
We believe the 3,130 figure means 3130 MicroSievert/hour, which would be highest reading yet recorded—about 310 millirems/hour. For comparison, the U.S. EPA allowable dose to a member of the public from a single reactor is 25 millirems/year, the U.S. NRC's allowable dose is 100 millirems/year from all nuclear sources.

From the regular media reports it appears that the Japanese have been able to resume pumping saltwater into Unit 2 at Fukashima, the plant where fuels rods were being exposed. That is better news in a dire situation.

I've watched Wolf Blitzer get outmaneuvered by an expert from a nuclear industry lobby just now. He claims that US nuclear plants in earthquake zones are built to standards appropriate to the conditions where they are located. Well, that was also true of Fukushima and the other troubled nuclear complexes in Japan, and the standards have proved inadequate. His back-up position was that we need to learn lessons from this event and move on with a new generation of improved nuclear plants. Well, there's something to be said for that, if the nuclear industry is willing to shut down all their existing plants for recertification. But Blitzer winged it to another aspect of the disaster.

Other "experts" are advocating fusion plants, a theoretically interesting concept but unproven as operational systems.

At this point I'd entertain the concept of switching to whale oil as an alternative (hey, whales, I'm only joking!), before plunking for fusion.

I heard on the radio coming back from errands that the fire truck providing the pump for the salt water for Unit 2 at Fukushima had run out of gas...the fuel rods were exposed and pressure was building up again in the reactor chamber.

Ads a note to everyone, looking closely at the cutaway diagram at Wikipedia for this type of reactor, there is a reactor chamber within which the fission reaction happens and heats the water coming in to boiling. The steam escapes out a pipe at the top and is used for running the electrical turbines. The entire reactor chamber is encased in a reactor containment vessel which evidently has not been breached. The reactor building was an additional layer of containment but the hydrogen blast blew out the roof and upper walls.

The saltwater is still being pumped in around the reactor chamber in Unit 1 and 3. It's unclear what is happening to the saltwater afterwards, whether it's being drained back into the bay. There are not a lot of good options left for dealing with that problem.

It ocurred to me that India has nuclear weapons. Not easy with a CANDU so I read up. My statements are way outta date! From Wiki...

In terms of safeguards against nuclear proliferation, CANDU reactors meet a similar level of international certification as other reactor designs. However, there is a common misconception that the plutonium for India's first nuclear detonation, conducted in 1974 Operation Smiling Buddha, was produced in a CANDU design. In fact, the plutonium was produced in the unsafeguarded CIRUS reactor whose design is based on the NRX, a Canadian research reactor. In addition to its two CANDU reactors, India has some unsafeguarded pressurised heavy water reactors (PHWRs) based on the CANDU design, and two safeguarded light-water reactors supplied by the United States. Plutonium has been extracted from the spent fuel from all of these sources in the PREFRE reprocessing facility.[18] While all of these reactors could in principle be used for plutonium production, India uses an Indian designed and built military reactor for plutonium production called Dhruva. It is believed that the Dhruva reactor design is derived from the CIRUS reactor, with the Dhruva being scaled-up for more efficient plutonium production. It is this reactor which is thought to have produced the plutonium for India's more recent (1998) Operation Shakti nuclear tests.[19]

Thw world NEEDS to be a different place.

The Hopi People are out there trying to get folks to realise that 2012 will bring their prophecy to fruition, of a massive World Change in how we live, think, act...

There have been many other disasters leading up to this one, but this one will, I think, finally begin to make people terrified of nuclear power...coupled with the financial situations around the world too, which is making people open their eyes to corruption, to absolute shitty behaviour..

Japan will change the world in many ways...be it is we, the people of this beautiful, BEAUTIFUL planet who have to change our ways, our thoughts, our outlooks with more speed and more strength than any tsunami could ever bring....because if we don't, we will also wreak more havoc than all the world's tsunamis put together.

Part 1 of The Indigenous Native American Prophecy

2012 The Indigenous Elders

EVERYTHING is going wrong, not just earthquakes, not just tsunamis, not just The Corporate Bastards..It is everything...even down to the humble bumble bee...who we cannot live without....

We have poisoned this planet, not just with the chemicals we have made and poured over the Land, but with the chemicals within our minds, that have become so out of balance, so destructive....

We do not need cars.

I live a very simple life compared to many, as I do not drive..so therefore I'm very local in where I live, how I live. A day out somewhere far away is a real treat. A trip on a train is exciting.
I've been on a plane, twice...never again, hated it. I don't need to visit every country in the world, I don't need the latest gizmos and gadgets...I'm quite happy even if computers, the internet disappear, to be honest, because much as it's done a great deal of good in connecting us all together, it has also made our lives so complicated..and I'm tired of answering many questions each time I make a phone call....I'm tired of the wa it's allowed evil people to come together, throwing all the good people into the age of suspicion, where all are viewed to be possibly guilty...

I'd love to go back to small communities, simple lives, where our work was mainly for ourselves, tilling the ground, growing our own food, taking care of our families, each other....and satisfaction came, at the end of the day, from a hot meal around a fire, not from a £10,000 computer or a £30,000 car.

We make things deliberately to wear out, so more profit can be made...and all it's ended up diong is wearing US all out with worry and anxiety......

This planet is our Home, the only one we have...and we are desecrating and destroying it. We forget this planet is not just OUR home though, that we share it with every other species under the sun...who have an equal right to be here, to exist on a wonderful planet...

I grieve...

I grieve for all that we are losing, all that we have lost...and all we have yet to lose....

The Diane Rheems show was most informative. The workers have done every procedure to minimize radiaton at a cost of about 3 billion dollars so far. The plutonium fuel is a 5% mix and not meant for these Mark 1 reactors which means they will melt at a lower temperature and be more toxic if a core breech should occur. France uses a 30% plutonium mix in a more advanced reactor. 18 workers have been hurt by blast or exposure. It seems that the chimney is not working so gas built up inside the building.

One could compare it to a 40 year old submarine that is below its design depth. As long as the containment "hull" holds up, the ship will survive.

They seem to be handling it very well so far - a little venting, a little explosion, a little more venting, another little explosion, nothing major yet, which, considering, is considerable, I think.

Donuel-

While I was reading that somewhat comforting quote about "meltdown clean-up" there was this cartoon Power Point presentation playing in my head, narrated by Woody Woodpecker.

I've got to get away from computers and cable for a while.

See you all later.

I do not besmirch anyone for wanting to believe what ever gives them comfort.


The industry standard explanation of how safe reactors are is to be expected/

Please note the "Ringer lInk" speaks in the subjective future pluferfect tense...


"After the meltdown, there would have been a waiting period for the intermediate radioactive materials to decay inside the reactor, and all radioactive particles to settle on a surface inside the containment. The cooling system would have been restored eventually, and the molten core cooled to a manageable temperature. The containment would have been cleaned up on the inside. Then a messy job of removing the molten core from the containment would have begun, packing the (now solid again) fuel bit by bit into transportation containers to be shipped to processing plants."



That sounds all well and good but with not water or electricty many of the assumptions made do not apply.

Yes, sorry. That should have been 1 and 3.

Peter-

Please proof what you are posting or review what you are reading before you post.

It's reactor units 1 and 3 which have had their roofs and upper walls blown off by hydrogen explosions so far. Units 4, 5, and 6 are in the same Fukushima complex but were shut down for regularly scheduled maintenance before the earthquake and the tsunami and hopefully will not be affected by what is currently happening in this complex. Unit 2 appears to be in serious trouble and I would expect that it too will experience a hydrogen explosion similar to what happened to 1 and 3. Is everyone keeping score now?

Now on the topic of fuel rods Unit 3 appears to be unique at the Fukushima complex, according to what's posted at Wikipedia:

From September 2010, unit 3 has been fueled by mixed-oxide (MOX) fuel rather than low enriched uranium (LEU) used in the other reactors.

The situation is serious enough without getting the basic facts incorrect. Of course, what's posted at Wkipedia may also be incorrect but please cite sources for such statements so that we can do some follow-up rather than argue about our deeply held opinions.

Donuel's scenario described above for what might happen in a nuclear meltdown at this complex may be all too true. No, it's unlikely to be a bomb like explosion but there will certainly be a major release of highly radioactive material to the environment.

My faith in the integrity of stainless steel containment vessels is challenged by the fact that these vessels are 40 years old and are weakened by embrittlement after being bombarded by radioactive isotopes for this period.

Well, it's time to go back and continue painting the living room in the vacant apartment across the hall. Why do I hear a Peter Berryman song echoing in my ears?

It's a a bit of wry irony a site advocating nuclear energy saying the world is not going to end while Fukushima 2 is believed to be in meltwown and reactors 1 and 4 damaged by hydrogen explosions barely hanging on and the wind is changing heightening fears any released radiation will go straight towards Tokyo.

No, the world won't be ending, it will be quite a different place though.
