Yomiuri on China Syndrome: Gov’t secretly figured out how far the melted fuel would burn through reactor pedestals — “Worst-possible scenario”

Published: October 16th, 2011 at 11:44 am ET


Tokyo, Oct. 15 — “The Japanese nuclear safety agency secretly calculated the possibility of a worst-case meltdown at Tokyo Electric Power Co.’s Fukushima No. 1 power plant,” reports the Yomiuri Simbun.

The agency began working on this report in late March, as Tepco was saying the nuclear fuel was only “slightly damaged.” It wasn’t until April 18 that the Japanese government acknowledged the fuel had begun to melt. Tepco did not acknowledge this until April 20.

In one scenario, all reactor cores dropped out at the same time. In another, melted fuel jetted out of the vessels.

China Syndrome

The calculations were premised on nuclear fuel at Reactors No. 1, 2 and 3 would melt down entirely, developing into a so-called “China syndrome,” the worst-possible scenario.

“Coined in the United States, the term China syndrome refers to an imagined worst-case meltdown of nuclear fuel that burns through the bottom of a containment vessel and eventually through the Earth’s crust until finally reaching China,” reports Yomiuri.

The agency’s calculations indicated that if water could not be injected, erosion could badly damage the reactor containment vessels’ 10-foot thick concrete walls.

The agency said it had roughly gauged the extent to which the pedestals (floor) of the containment vessels would be eroded should all the melted fuel drop through the pressure vessel of the three reactors.

The erosion could “possibly” stop after vessel wall was eroded to a depth of around 6 feet in eight days.

    Please sign the petition to end nuclear energy in the U.S. We cannot afford to continue putting our own nation at risk, now that we can plainly see that even in technologically advanced Japan — they have no means of resolving this kind of crisis, let alone preventing it in the first place. Do we really need our very own, homegrown Fukushima before we close our nuclear power plants? Are the Germans THAT much smarter than we are?!


  • arclight arclight

    suppose if the emergency is under control they wouldnt mind releasing the spectrographic results from all them universities and private laboratories that are keeping the information secret until when??

    “It said the calculation results were conveyed to the agency, but it is unknown whether the information was shared with the Cabinet Office or other government organizations.

    Regarding the announcement of the calculations a half year after the outbreak of the crisis, the JNES said that although the calculations were exclusively for the sake of studies within the agency and Tepco, it decided to make them public as the initial phase of coping with the crisis has finished.”

    Looks like the 3 cores are in full China syndrome to me. 10 feet of concrete will not matter after that quake because of the cracks it sustained. What they should calculate is what happens when the cores are melting into the soil under the containment. I don’t think there is a way to measure the insane amount of nuclear fission products that would be released from the core being exposed to the earth itself. Concrete could contain the melted fuel for a limited time period, but what happens when the seawater washes over the cores and carries fission products out the cracks in containment? No one knows and TEPCO wants to keep it that way.

        “Update 9/7/11: On August 20th, the POTRBLOG team reported that the 178X background radioactive rain fall “may be indicative of a RECENT SIGNIFICANT radiological event in Fukushima.” That assessment now appears to be now born out by a Japanese report of large Iodine-131 detections in radioactive sewage collected in Oshu City 180+ KM north of Fukushima on August 25th. The collection date of the sewage sample correlates to several earthquakes during the period and reports of radioactive steam rising up from cracks in the ground at the Fukushima nuclear site. It also correlates strongly with large increases in radioactive detection along the jetstream in North America.

        “Taken together, the data is indicative of Coruim entering the ground water, becoming re-critical, and inducing the release/production of large amounts of Radon 222. The associated detections of extremely large quantities of Radon Daughters in the radioactive fallout raining down on North America are likely indicators of harder to detect longer half life fallout in the same rainfall.”

        “On impact, depleted uranium ignites. It generates fires and explosions, and death to those in near proximity. In addition, it also generates airborne oxides. This is where the great and long-term damage occurs to millions; 40% of the depleted uranium is left on the battlefield after the battle….
        “Once inhaled, which DUO universally is, it is the most destructive form of ionizing radiation by far. One gram of DU releases 13,000 alpha particles (a helium nucleus) per second. One alpha particle can cause cancer under the right conditions.
        “DU inhaled nano particles, less than 10 microns big, stay lodged in tissue for decades, emitting radiation that does great and cumulative damage.
        “Depleted uranium in your body is like miniature cannons going off for decades inside your body. They fire high-energy particles at 12,000 shots per second. They wreck and damage DNA chains. They induce chemical changes inside cells. And if the particles survive, they can replicate and do even more damage.

        “DU is a worldwide toxin. Because it is aerosolized, it can travel great distances from where it is used to penetrate armor in a war. It began to be used in war in the 1973 Arab-Israeli war, then in the Gulf War in 1990-91, and continues to be used today.
        “Gulf War veterans were found to have DU in their clothing, bodies, and semen; 67 percent of them have offspring with birth defects. Fibromyalgia, chronic fatigue, and chronic neurological conditions are much more common among them than in the general public. Lauren Moret, eminent scientist, has stated that DU is the main cause of Gulf War Syndrome.
        Whereas only 400 soldiers were killed in the war, 11,000 of the 580,000 soldiers are now deceased, and over 325,000 are on permanent disability as of 2000.

        ***Since the earthquake and tsunami last Friday, four nuclear power plants in northeastern Japan reported damage. Most serious damage appear to be in the Fukushima Daiichi complex where a meltdown or ”partial meltdown” has been found in Unit 1 and 3.
        ”The accident should be classified as the worst on the scale – Fukushima is as serious as Chernobyl”

        Frigyes Reisch, 78, is associate professor of nuclear safety at the Royal Institute of Technology (KTH). Over 27 years, until 1997, he worked for the Nuclear Power Inspectorate, SKI. In 1993 he worked a year for the IAEA as an international educator in the INES scale, including in Russia and the Czech Republic. Frigyes Reisch believes that the Japanese authorities blinds the dangers of Fukushima to keep people quiet – but there is also a national scope:
        – There is tremendous commercial interest in this. The entire world’s nuclear industry is Japanese.

        As an example, he mention the second global nuclear power giant, General Electric Hitachi Nuclear Energy, has Japanese majority ownership.
        – Given all the rescue workers who worked closely with the affected units and inhaled radioactive steam, it´s in reality impossible to not die of radiation. It’s not good. I do not know how many people who live north of Fukushima, but I guess it is so densely populated that there are a few million,” said Frigyes Reisch.

        So far, winds have been westerly and blowing out the radioactivity of the Pacific Ocean. But according to forecasts, they will during the day today to turn around and start blowing north – with the chance of precipitation. How far the radioactive particles can be spread is due to local conditions. After the Chernobyl accident Gavle, 1000 km from Chernobyl, had most radioactive precipitation in Sweden.

  • Flapdoodle Flapdoodle

    If someone came to me and asked how far it would melt down, I would want to know what the rock, and soil was like under the reactor. Then I would ask if there were known water issues; underground stream or river, how high is the water table. I will bet zero or minimal research was conducted prior to construction.

    I have never seen a molten puddle of reactor core, but I doubt it would stay as a pancake for long. The center would likely be hottest, so it would try to assume a conical shape. If the ground can be melted/vaporized easily, it may try to assume the shape of a column.

    • Misitu

      The plant is built on a platform excavated from what was a 35m high hill. The turbine hall basement extends to below sea level. The buildings are a few metres from the sea. Groundwater is therefore level with the basement walls or just below; however, if the subsoil or immediate bedrock is impervious then the flowing groundwater will be below that. That said, in the contrary case e.g. clays they would be dampish due to being so near the sea.

      The records IIRC show that the immediate bedrock as such is a mixed series of mudstones with sandy lenses, or similar. If so there are likely fissures which would contain water.

      For this discussion we do not I think need to go any deeper.

      My best bet is that the corium has already created a dry zone around itself by heating up the neighbouring rock enough to release any water as steam.

      However, the unpredictability of the corium progress implies that all bets are off as to prognosis, though in extremis I would say that the steam generation could continue indefinitely, given adequate rainfall. Given an extended drought followed by copious rain COULD lead to the potential for explosions.

      I found reports from Tepco re two geological surveys that were slated to happen following a recent seismic incident prior to 2011 (2006 or 2007 I think). Having asked for results of these surveys and found none I came to the (not surprising) conclusion that the surveys never took place.

      I asked both here and on Physics Forums.

      As always, happy for any corrections to obviate Blind Alley (aka Shitcreek) Syndrome.

      Heat applied to mudstones will eventually metamorphose the clay minerals to shale then slate then micaschist; for sandstones will metamorphose the quartz to quartzite and/or gneiss and/or granite. These rocks are found at the root of mountain ranges and are real hard guys. It would be like the heat of the corium causing the rocks to form a hard insulating layer.

      Is my best guess but someone might like to check…

      • Misitu

        Is my best guess but someone might like to check the reported and estimated temperatures of the coriums and the rock types I mentioned…

        • Misitu

          Silica 1830 deg C
          Granite 3100 deg C
          Corium 2500 (maybe up to 2900) deg C
          Clay (kaolin) 3275 deg C
          Minerals found in igneous and metamorphic rocks:
          Plagioclase feldspar 1825°K.
          Pyroxene is 1650°K.
          Potential for corium melting granite is zero, but it can certainly metamorphose sedimentary rocks like clays, mudstones and sandstones, but those would tend to form an insulating layer. Water would be driven off probably through expansion cracks in the strata above the corium.

          One might suppose that a really really bad possibility is that the corium heats up the surrounding rocks into a very resistant crust, maybe several inches thick (I am making this up as I go now, it could be feet thick …) and then when the phase changes occur in the corium due to transient volumes of gas being generated we end up with a very severe increase of pressure situation.


          no need to spell this out further.

        The turbine buildings are on landfill.

        • Misitu

          Hi Anne, it was myself that postulated landfill originally as the geol map of Japan said “Holocene Reclaimed Land” implying landfill, e.g. marine reclamation by dredging.

          Subsequent to that, maybe a month later, an article appeared in one of the Shimbuns showing that Fuxu daiichi was constructed after excavating a seashore hill. The reason for doing this was the economics of the operating plant, it being cheap to pump the cooling water a few inches up from the sea rather than 100ft to the top of the hill. So once again the lie is given to the cheapness of nuclear electricity generation: the unsafe location was affordable, the safe location was not.

          The turbine hall floor is a few metres below sea level.

          Landfill may have been used for hardcore in the foundations but anything other than rubble would have been an imbecility one step too far even for what we know of the former institution known as Tepco.

          Apologies for the earlier misunderstanding: it’s a risk of this site that we have limited information, and sometimes because of that reach wrong conclusions. I did try to correct it at the time.


          • Dr. Anne Lee Tomlinson Maziar anne

            @ Misitu, I got this information from a report on the internet that showed a diagram of the plant from the side which showed the turbine buildings on landfill and which I posted some time ago. There are probably other sources as well.

            Anne: I remember that diagram and I believe that it is a fantasy principally because there is no granite at the surface at that site and it would not magically stop just there. But I will look for the other diagrams that seem more in tune with geological realities.

            Toyoda also cited two other reasons for Tepco clearing away the bluff — seawater pumps used to provide coolant water

            reator pressure vessels, were expected to be brought in by boat.

            In fact, Tepco decided to build the plant on low ground based on a cost-benefit calculation of the operating costs

            of the seawater pumps, according to two research papers separately written by senior Tepco engineers in the 1960s.

            If the seawater pumps were placed on high ground, their operating costs would be accordingly higher.

            the circulation water pumps,” wrote Hiroshi Kaburaki, then deputy head of the Tepco’s construction office at the

            Fukushima No. 1 plant, in the January 1969 edition of Hatsuden Suiryoku, a technical magazine on power plants.

            Post from a Japanese Geologist:

            “As for Fukushima`s geology, *yes, it has been long known that around the Fukushima Daiichi Plant is sedimentary

            rock Taga Group; around the plant this rock is called the Tomioka Formation, whch is made of coarse sandstone (or

            Grit) and tuffaceous siltstone. It`s pity that*no*geologists*(as*far as I know)*have warned the vulnebility of the

            Fukushima Daiichi Plant in terms of…

            … It`s pity that*no*geologists*(as*far as I know)*have warned the vulnebility of the

            Fukushima Daiichi Plant in terms of geology, as it won’t take a rocket science (but so simple and clear) to check

            this out. But instead, I think most of us trusted info provided by Tepco, such as videos in*nuclear safety which

            states that “this region*of Fukushima Daiichi Plant have never experienced major earthquake or tsunami over the past

            400 years”. *
            As for the groundwater-flow information, I don`t know. I checked several website, but I could not find one,

            including the one in Japanese. As the bedrock of the area is made of coarse sandstone, the rock is highly permeable

            and has plenty of waters flowing in the underground of the plain (but in a very very*slow speed) around the*nuke

            plant. The source (catchment of rain) is the nearby Abukuma mountains, and the groundwater of this nature will spend

            hundred or more years to flow from the mountains to the coastline. But I do not have data to prove this – I am just

            stating a general rule.”


            “I have talked with some of my colleagues (geology professors) today, and some of them knew for many years/decades

            that the bed rock of the Fukushima Daiichi Nuke Power Plant is soft sedimentary rock. They do not know why

            government (both national and local/prefectural) approved for the construction of the plant on such a bad spot, and

            can only think of*unethical acts of polititians and the industry.*Also,*my colleagues warn that the type of bed

            rock, which geologists identify,*and the strength/suitability of the*bed rock, which soil/geo-engineers determine,

            is different, even though I would*still support that*young sedimentary rocks below the Fukushima Daiichi Nuke Plant

            is NOT*suitable for constructing buildings that have to endure earthquakes. ”

My impression is that the slideshow is a bit of a hack put together in haste to meet a deadline, probably to keep up the “reassure the stupid people” pressure.

            Why Underground Entombment At
            Fukushima Daiichi Won’t Succeed
            By Yoichi Shimatsu, 7-28-11
            “Fukushima No.1 rests on landfill comprising loose rock and sand over the natural seabed and is positioned only a couple of meters above the high tide mark. Water seepage and earthquake-caused liquefaction have seriously disturbed this rather weak soil structure….
            “Much of the danger comes from simpler processes. Extremely hot magma, consisting of nuclear residues mixed with soil minerals, will boil any sea water seeping underground, creating pressurized steam.Think of oatmeal cooking in a pot and how bubbles create blow holes. The same is happening inside the landfill.
            “The steam-created tubes harden when they cool, leaving lines of structural weakness. Eventually, these air pockets will collapse, and the massive weight of the water-filled reactors, piles of spent rods and their supporting structures will drop into deep sinkholes.

            “If the magma tubes become filled with sea water, the landfill will resemble a gigantic sponge, prone to liquefaction and collapse under earthquake motion. Even the resonance vibrations from large machines could trigger the sudden opening of new sinkholes.

            “Water holds other dangers as well, since it is a better medium for nuclear fission than the mix of stones, dirt and concrete now under the reactors. Once sea water seeps into the newly opened underground channels, the fissile particles will become free-floating and fire neutrons into bits of uranium, plutonium and other isotopes, triggering cascades of fission. The resulting steam pressure is volcanic, bursting out of the ground and spewing vast amounts of radioactive material into the atmosphere. The oatmeal spatters across the stove top. …”

            March 30, 2011
            “But a review of company and regulatory records shows that Japan and its largest utility repeatedly downplayed dangers and ignored warnings – including a 2007 tsunami study from Tokyo Electric Power Company’s senior safety engineer.
            “’We still have the possibilities that the tsunami height exceeds the determined design height due to the uncertainties regarding the tsunami phenomenon,’ Tokyo Electric researchers said in a report reviewed by Reuters.

          Hydraulic tomography in fractured granite: Mizunami Underground Research site, Japan

          “1. Introduction
          [2] The accurate prediction of fluid flow and radionuclide transport in the subsurface is critical in the design of highlevel nuclear waste repositories. Geologic formations of low hydraulic conductivity (K) of igneous origins (e.g., crystalline rocks such as granite, basalt, tuffs, etc.) have been suggested as suitable sites for the construction of nuclear waste repositories in many countries. These geologic formations, however, often contain interconnected fractures or fault zones on a continuum of scales [Bonnet et al., 2001] caused by cooling and/or tectonic processes. These fractures strongly affect groundwater flow and contaminant transport, as flow is predominantly carried through a limited number of major fractures. Therefore, the accurate characterization of the limited number of large fractures and fault zones, as well as their connectivity is of paramount importance in predicting the hydraulic behavior around a nuclear waste repository….

          “ [4] A fractured geologic medium is a mixture of two or more distinct populations of voids (i.e., fractures of various sizes and the matrix pore space). In general, fractures are highly elongated voids (open conduits), which are generally sparsely distributed in geologic media. The matrix pore space of geologic media, on the other hand, is an aggregation of a large number of small granular voids…

          “[14] The Mizunami Underground Research Laboratory (MIU) is located in Mizunami, in the central part of the main island (Honshu) of Japan. The site has been operated by the Japan Atomic Energy Agency (JAEA) since 2002. Currently, the underground research facility is under construction for deep subsurface scientific investigations. Two 1,000-m deep shafts and several drifts are currently being excavated for geoscientific research as well as development and assessment of deep subsurface engineering techniques.

          • Dr. Anne Lee Tomlinson Maziar anne

            JAEA is carrying out a wide range of research in an effort to build a firm scientific and technological basis for geological
            disposal of high-level nuclear waste.

            “2.2. Site Geology and Investigations
            “[15] The MIU site lies at the border of Cretaceous plutonic rocks of the Ryoke Belt and Mesozoic sedimentary rock of the Mino Belt. The research galleries of the MIU are being constructed in the Cretaceous Toki Granite, which forms the basement complex in the area as shown in a conceptual cross-sectional view of the site (Figure 1; see Figure 2 for the location of the cross section). The site geology consists of the Miocene Mizunami sedimentary rock sequence and the underlying Toki granite. The Mizunami Group is divided into Akeyo Formation, Hongo
            Formation (AK/HG in Figure 1) and Toki Lignite–bearing Formation (TK in Figure 1). The Akeyo and Hongo Formations are at the top and composed of tuffaceous sandstone, mudstone, granular conglomerate and basal conglomerate. The Toki Lignite–bearing Formation is mainly composed of muddy sandstone, tuffaceous sandstone, granular conglomerate, lignite and basal conglomerate at the bottom [Itoigawa, 1980]. The contact between the Hongo formation and the Toki Lignite–bearing formation is conceptualized to be a flow barrier. Toki Granite, which underlies the Toki Lignite–bearing formation, is composed of coarse-to-medium-grained biotite granite. The granite is highly fractured at depths between 300–500 m with dips of fractures that are less than 30 degrees. Beneath the
            highly fractured domain (upper highly fractured domain: UHFD in Figure 1) is a granitic body which is less fractured (lower sparsely fractured domain: LSFD in Figure 1), which is known to extend to large depths. Previous research and geological investigations at the site have shown that there are low-angle fracture zones (LAFZ in Figure 1) within the UHFD.

          • Dr. Anne Lee Tomlinson Maziar anne

            . In addition, there is evidence of
            the existence of various flow barriers (fault zones) including a prominent one that runs through the site oriented North-North-West (NNW) designated as fault IF_SB3_02.
            “[16] Within the MIU construction site boundary, numerous lineaments and potential fracture zones have been identified through lineament and seismic surveys. Figure 2 shows a plan view of the site map with the locations of the boreholes, the locations of the main (MS) and ventilation shafts (VS), and the approximate extent of fault IF_SB3_02. In particular, this fault was recognized during early site mapping at a roadside outcropping and at a preexisting underground tunnel network as being potentially significant to groundwater flow because of the occurrence of fault gouge. The fault appears to be a normal fault, dipping approximately 85 degrees with about one meter of vertical displacement observed at the road cut, while the lateral displacement is unknown at this time. It has been intersected by borehole MSB-3 and by the main shaft. The fault
            has not been located in the northwest edge of the site. This fault can be seen to effectively compartmentalize the site into northeast and southwest regions. The hydrogeologic characteristics of these lineaments and faults, including those for fault IF_SB3_02, are largely unknown….”

          Fukushima Daiichi Nuclear Power Plant

          The location of the plant was on a bluff which was originally 35-meters above sea level. During construction, however, TEPCO lowered the height of the bluff by 25-meters. One reason the bluff was lowered was so that the base of the reactors could be constructed on solid bedrock to mitigate the threat posed by earthquakes.

          Fukushima plant site originally was a hill safe from tsunami
          Tuesday, July 12, 2011
          “Katsumi Naganuma, 70, a former worker at Tokyo Electric Power Co., feels particular guilt because he knows that a 35-meter-high, tsunami-safe, bluff overlooking the sea was shaved down to build the Fukushima plant closer to sea level more than 40 years ago.
          “Tepco, assuming tsunami 3.1 meters or higher would never hit the coast, cut down the bluff by some 25 meters and erected the plant on artificially prepared ground only 10 meters above sea level.
          “’When I see the situation now, I feel it was wrong to clear that much of the hill away,’ said Naganuma, who worked at Tepco’s local office preparing for the construction in the late 1960s.
          “’If they did not dig the ground down that much, we would not have faced this situation. (The nuclear disaster) would not have happened,’ said Naganuma….”

          • Dr. Anne Lee Tomlinson Maziar anne

            Actually, if the earthquake damaged the pipes causing the coolant to leak out, the disaster would have happened even without the tsunami. However, the site itself may have been much more prone to damage from the earthquake than if it had been built on the original bluff. However, the bluff may have been originally too porous to allow the plant to have been built on it.

            The real tragedy is that the ill chosen site was doomed to tragedy because of three more mistakes. 1) Reactor #3 was never built to have used MOX fuel. 2) The plant was never built to last more than 20 years. So granting another license after 40 years use was a colossal mistake. 3) If there was additional MOX fuel stored there and a weapons making facility as well…..

            Bad judgment after bad judgment created the largest and most devastating environmental disaster to date. But has the world learned its lesson? The nuclear industry just keeps plowing ahead as if it has blinders on.

    So from the scale rating nuclear accidents it advances by order of ten for each number. 7 is the maximum, but if it were expanded then ten times Chernobyl is an 8 and a 9 is 100X Chernobyl.

    The Japanese nuke industry has committed suicide on their on shores. The outside players in this business rushed in to try and save the reputation of nuclear power. It was quite a show using all the tricks of controlling media, experts opinion and govt. agencies to convince you to remain calm. Well the SHTF and the price to pay for our stupidity cannot be put on the creditcard for future generations to pay off.

    • lam335 lam335

      These people have not committed suicide–they have committed mass murder.

      And yet the Japanese nuke industry is still actively trying to export its “technology”” to other countries. (Of course, these were GE reactors, but I don’t see GE backing away from nuclear either).

      • lam335 lam335

        The nuke industry in the U.S. also continues playing the same old games, seeking to extend licenses, increase the power output at old reactors, and deny/diminish/refuse to disclose anytime something goes wrong.

        They are doing everything in their power NOT to let FUK undermine their so-called renaissance–the industry’s lobbying and propaganda wing, the Nuclear Energy Institute, recently commissioned a “survey” claiming that a majority of Americans “still” support nuclear power:

        “Six months after the Fukushima Daiichi accident in Japan, solid majorities of Americans still view nuclear energy favorably, still support the extension of operating licenses at existing facilities that meet federal safety standards, and still believe that construction of a new reactor is acceptable at the site of the nearest nuclear power plant that already is operating, a new national survey shows.”


        This is a load of crap (forgive my language, but I call it as I see it). If these survey results are accurate, it is only because the media has barely covered the on-going crisis since March and the vast majority of Americans are blissfully ignoring it. Most think the crisis is “over” and most have no idea just how much it released–and continues to release. The fact that massive amounts of Plutonium were released in the first week and no media reported on it for months is incomprehensible.

        • bluerthanblu bluerthanblu

          Bisconti Research Inc. has numerous Japanese clients in the nuclear industry. Without a doubt, this large survey sampling of public opinion is not an objective information source. Media, energy companies, and state/govt/int’l nuclear regulation groups are involved in a big business ‘menage a trois’ (good political cartoon material. Would that get the message out best, lol?). A comment like: ‘A nationally representative sample of 1,000 U.S. adults was interviewed by telephone, with a margin of error of plus or minus three percentage points’ is made to sound like the data is ‘the truth’ to people unfamiliar with nuclear science or statistics data (i.e., make the data ‘fit’ your desired results by set up).

          Just got thru viewing Gordon Edwards presentation (Prt 3 of 5) about ‘Radiation and the Ultimate Waste’ problem that remains unsolved to date. The fact that rad waste can’t be destroyed is asking nature to ‘put it on hold’ for 10,000+ years (into infinity). Plutonium waste puts out heat underground and degrades metal containers. You can’t bury waste fast enough with the amount produced from one reactor. Uranium mining leaves the rock more radioactive than the uranium! Edwards says nature will recycle what is not destroyed completely. We cannot destroy the waste at this time. A comment left out of the vid, due to time, is that the answer to any waste issue by nuc proponents is that ‘it’s a PR problem, not a technical one.’ See Edwards’ vids at: http://www.youtube.com/watch?v=FjlFOEtsDRQ&feature=related.

          Clearly, nuc media spin obfuscates public awareness to keep control of public opinion. Busby has some theories of the difference between pro-nuc and no-nuke people, one of ‘control’ vs. ‘fear of chaos’ types, at: http://www.youtube.com/watch?v=CjOPoeRT2CM&feature=autoplay&list=UL12EEeaMuEdU&lf=mfu_in_order&playnext=2.
