Fukushima... Corium quake??? activity right now..... sea temp unbelievable...

all of Earth will become "Hell on Earth"

But the fire brigade at Chernobyl did exactly that, so much so that the pool underneath had to be swam into by divers and it took a week to drain it all out. You know the story I can see from your posts. Also Akimov and Lelechenko also spent hours (literally melting their flesh off) pumping water into the then non existent core, still no major steam explosion.

Agreed it had no chance of putting it out and made thing much worse but unless there is a large contact of fuel with a large body of water, suddenly, it is possible that we would not see the catastrophic steam explosion that is usually forecast with a melt down. If this occurs deep underground and contact timeframe is slow enough, it may just boil and build up steam pressure that pushes out in all directions, finding the path of least resistance. Also the earth can act as in insulator not allowing the mass to exchange heat and increasing the sink rate.

The problem stems from the fact that there is no prior real world data for any of our conjecture.. Anything is possible IMO

No, water will make it worse. All it does is cool the core and bring atoms closer to each other, increasing the fission events from immediate release neutrons.

Keep in mind the balanced core uses both immediate and delayed release neutrons. Meaning the fission blob grows at the slow rate of delayed release neutrons.

But cool it and the thing flashes over violently. Expands as far as the fuel will allow and then trips over itself and contracts. This action rings until the sudden in flux of cooling material is resolved.


Lead absorbs neutrons well, which is ideal for nuclear suppression.




The more heat you pull from the reaction, the more violent the reaction becomes. It's a balance of nature in a run away situation.

As you pull more heat, more radiation is emitted all around. Making the situation even worse and possibly explosive.

I don't disagree with what you are saying, but certainly coolant has been dumped on hot corium before without massive steam explosions and rapid physical expansion, TMI was melted, they cooled with water... Same as Ignalina. By what you are positing, the ECCS injection over corium would cause the volume to expand so much and rapidly that it would burst the containment vessel and this did not happen at TMI nor the BWRs that got away on nuclear submarines and the icebreaker Lenin (actual melt). It makes it worse to be sure, but it's not like trying to put out a fire with jet fuel.

i cannot concure.. 'corium', is that wonderful word we use for the unknown conversion of properties that were not 'thought about'.... that being, 'corium' is an unstable and unknown element that should not be released into the environment without superflouse study....

if they had found an answer.. really?.. should that have been done in 1950 or 2011?......

was the 'race so important' to boil the water to make plutonium?...... really?

While I agree that it is a toxic stew with unknown properties and behaviors, and furthermore I believe that nuclear power serves only the arms industry and depopulation agenda; I have cited several real world examples where by distilled water was used over the material without the catastrophic consequences offered above. If that was an absolute fact, the emergency core cooling system and reactor protection system controlling it would be like a cocked pistol hidden inside every core, the current practical examples do not support this.

how can anyone ever eat anything out of the ocean EVER? This blows my mind. WE need to leave the ocean alone, and let the animals in it make a come-back, if they can, while FUKU KEEPS SPILLING POISON!

EV...thanks for contributing to this thred, I have learned much from you.

So... no reliable reports? Just going off w/o any credible information? GTFO, why is this bull pinned?

Cs-134 is also produced and dispersed, it has a 2-year half-life. Caesium is soluble and can be taken into the body, but does not concentrate in any particular organs, and has a biological half-life of about 70 days. In assessing the significance of atmospheric releases, the Cs-137 figure is multiplied by 40 and added to the I-131 number to give an "iodine-131 equivalent" figure.

A significant problem in tracking radioactive release was that 23 out of the 24 radiation monitoring stations on the plant site were disabled by the tsunami.

ok, but what now, your monitoring is down and/or lying....
(see my links previous)

<snip>
After the hydrogen explosion in unit 1 on 12 March, some radioactive caesium and iodine were detected in the vicinity of the plant, having been released via the venting. Further I-131 and Cs-137 and Cs-134 were apparently released during the following few days, particularly following the hydrogen explosion at unit 3 on 14th and in unit 4 on 15th. Considerable amounts of xenon-133 and iodine-131 were vented, but most of the caesium-137 (14 out of 15 PBq total) along with most of the Cs-134 apparently came from unit 2 on or after the 15th. Also ten times more iodine is attributed to unit 2 than unit 1, while unit 3 produced half as much as unit 1. However, there remains some uncertainty about the exact sources and timings of the radioactive releases

unkown releases?!!??!!?!? in this day and age??? loosers....

<snip>
* The Cs-137 figure is multiplied by 40 in arriving at an "iodine-131 equivalent" figure, due to its much longer half-life. Cs-134 is multiplied by 4.

break out your scientic calculator for that one

<snip>Radiation exposure in plant and beyond

To 31 December 2011, Tepco had checked the radiation exposure of 19,594 people who had worked on the site since 11 March, for many of these considering both external dose and internal doses (measured with whole-body counters). It reported that 167 workers had received doses over 100 mSv. Of these 135 had received 100 to 150 mSv, 23 150-200 mSv, three more 200-250 mSv, and six had received over 250 mSv (309 to 678 mSv) apparently due to inhaling iodine-131 fume early on. The latter included the two unit 3-4 control room operators in the first two days who had not been wearing breathing apparatus. There were up to 200 workers on site each day. Recovery workers are wearing personal monitors, with breathing apparatus and protective clothing which protect against alpha and beta radiation. So far over 3500 of some 3700 workers at the damaged Daiichi plant have received internal check-ups for radiation exposure, giving whole body count estimates. The level of 250 mSv was the allowable maximum short-term dose for Fukushima accident clean-up workers through to December 2011, 500 mSv is the international allowable short-term dose "for emergency workers taking life-saving actions". Since January 2012 the allowable maximum has reverted to 50 mSv/yr.

<snip>Remediation

Tepco published a 6- to 9-month plan on 17 April 2011 for dealing with the disabled Fukushima reactors, and updated this several times subsequently. Remediation is proceeding approximately as planned.

At the end of August 2011 Tepco announced its general plan for proceeding with removing fuel from the four units, initially from the spent fuel ponds and then from the actual reactors.

Storage ponds: First, debris will be removed from the upper parts of the reactor buildings using large cranes and heavy machinery. Covers will be built, and overhead cranes and fuel handling machines necessary to remove the spent fuel assemblies will be reinstalled. Casks to transfer the removed fuel to the central spent fuel facility will also be designed and manufactured using existing cask technology.

In July 2012 two unused fuel assemblies were removed from unit 4 pond, and were found to be in good shape, with no deformation or corrosion. Tepco plans to start removal of all fuel from the pond in December 2013.

Reactors: First it will be necessary to identify the locations of leaks from the primary containment vessels (PCVs) and reactor buildings using manual and remotely controlled dosimeters, cameras, etc., and indirectly analyse conditions inside the PCVs from the outside via measurements of gamma rays, echo soundings, etc. Any leakage points will be repaired and both reactor vessels (RPVs) and PCVs filled with water sufficient to achieve shielding. Then the vessel heads will be removed. The location of melted fuel and corium will then be established. In particular, the distribution of damaged fuel believed to have flowed out from the reactor pressure vessels (RPVs) into PCVs will be ascertained, and it will be sampled and analysed. After examination of the inside of the reactors, states of the damaged fuel rods and reactor core internals, sampling will be done and the damaged core material will be removed from the RPVs as well as from the PCVs. The whole process will be complex and slow, since safety remains paramount. In December Tepco estimated that the fuel would be removed from the reactors within 25 years - in line with US experience at Three Mile Island, though other estimates suggest ten years.

The four reactors will be completely demolished in 30-40 years - much the same time frame as for any nuclear plant.

Earlier, consortia led by both Hitachi-GE and Toshiba submitted proposals to Tepco for decommissioning units 1-4. This would generally involve removing the fuel and then sealing them for a further decade or two while the activation products in the steel of the reactor pressure vessels decay. They can then be demolished. As noted above, removal of the very degraded fuel will be a long process in units 1-3, but will draw on experience at Three Mile Island in USA. In January it was reported that an industry consortium (Hitachi GE Nuclear Energy, Mitsubishi Heavy Industries and Toshiba) would determine how to locate fuel debris inside units 1-3 and how to fill the pressure vessels with water.

Tepco has allocated ¥207 billion ($2.53 billion) in its accounts for decommissioning units 1 to 4. The government has allocated ¥1150 billion ($15 billion) for decontamination in the region, with the promise of more if needed.

A 12-member international expert team assembled by the IAEA at the request of the Japanese government reported in October on remediation strategies for contaminated land. The mission focused on the remediation of the affected areas outside of the 20 km restricted area. The team said that it agreed with the prioritization and the general strategy being implemented, but advised the government to focus on actual dose reduction. They should "avoid over-conservatism" which "could not effectively contribute to the reduction of exposure doses" to people. It warned the government against being preoccupied with "contamination concentrations rather than dose levels," since this "does not automatically lead to reduction of doses for the public." The team's report calls on the Japanese authorities to "maintain their focus on remediation activities that bring best results in reducing the doses to the public."

Return of evacuees

Preparing for this remains a high priority and the evacuation zone will be decontaminated where required and possible, so that evacuees (reportedly some 160,000) can return without undue delay. There are many cases of evacuation stress including transfer trauma among evacuees, and once the situation stabilised at the plant it appeared that these outweighed the radiological hazards of returning.

In December the government said that where annual radiation dose would be below 20 mSv/yr, the government would help residents return home as soon as possible and assist local municipalities with decontamination and repair of infrastructure. In areas where radiation levels are over 20 mSv/yr evacuees will be asked to continue living elsewhere for “a few years” until the government completes decontamination and recovery work. The government will consider purchasing land and houses from residents of these areas if the evacuees wish to sell them.

From April 2012 part of the 20-km radius area and the portion of Minami Soma city extending north from it, were re-categorised by the Environment Ministry: below 20 mSv/yr, evacuation called off; 20-50 mSv/yr "restrict residency", with entry for specific purposes and no protective equipment required and remediation action to be completed in March 2014; and over 50 mSv/yr "difficulty of return", with restricted entry and remediation deferred. These restricted areas, comprising about half of the 20-km radius evacuation zone, are not expected to drop below 20 mSv/yr before about March 2016. Such areas add to those devastated by the tsunami, where rebuilding is very uncertain.

In July 2012 this zoning was extended by METI to Iitate Village, an area 28-45 km northwest of the Daiichi plant and contiguous with the northern part of Minami Soma city. Most of Iitate’s residents can now return without protective gear or monitoring equipment but not stay overnight, since annual exposure on a continuous basis would be no more than 20 mSv in some parts and 20-50 mSv in others. However, one area of Iitate (about 10 sq km), and a part of Minami Soma joining it and extending into the 20-km radius, remain fully evacuated. In August the Naraha town area south of the plant was added to the minimally-restricted category, below 20 mSv if continually occupied. In December parts of Okuma-machi southwest of the plant and close to it were de-restricted on the same basis. Thus more than half of the original evacuated area (20 km radius plus Iitate and Minami Soma) is now accessible without protective gear or monitoring. The area of Namie town and also Katsurao village outside the 20 km radius remain uncategorised.

How much has temp gone up . As too hard to read link . If its 5 degrees or more ,serious damage for all plants and critters in the effected zone . No more fish in that part of the world. Why do you think all the dolphins bugged out a month or so ago.
