So, this is what is ACTUALLY happening.

Breakdown of the mess

* Reactor #1 has a little bit of fuel melted.

* Venting of steam at reactors 1, 2, 3 blew apart the outer buildings.

* All cooling pumps are out of order, they are pretty much dumping seawater on the rods and letting t boil off, hence the steam.

* Hydrogen is being formed in the reactors, as the seawater is reacting with metal inside them. This hydrogen caused an explosion at reactor 2 which damaged to its suppression pool, which helps to cool and trap the majority of cesium, iodine, strontium in its water.

* There was a pressure drop at reactor 2, suggesting the vessel has been breached. The government gave no update on the status of a steel container surrounding the core of the plant's No.2 reactor, deemed by observers as most at risk of a meltdown.

* Radiation levels at the quake-stricken Fukushima Daiichi complex have varied wildly, with a reading of 11,930 microsieverts at the main gate of the plant at 0000 GMT, up from 596 microsieverts as of 0630 GMT.

* Elsewhere at the plant, levels reached as high as 400,000 microsieverts an hour (or 400 millisieverts an hour).

* Later, there was a fire and explosion at the complex's No. 4 reactor and this is likely to have contributed to rising radiation levels.

* The No. 4 reactor had been shut down for maintenance ahead of the quake, but a spent-fuel cooling pool associated with that reactor caught fire, causing the explosion.

* The No.4 reactor's cooling pool, where spent nuclear fuel is stored, is at 84*c (supposed to be 40) and the water level is falling.

*Radiation levels at the reactor have become too high for normal work in the control room. Workers cannot stay in the room long and so are going in and out alongside monitoring from a different room.


Report from Kyodo on Prime Minister Naoto Kan's anger at TEPCO:

Japan's prime minister was furious with the power firm at the centre of the nuclear crisis for taking so long to inform his office about a blast at a stricken reactor plant, demanding "What the hell is going on?".

"The TV reported an explosion. But nothing was said to the the premier's office for about an hour," a Kyodo reporter quoted Kan telling power company executives.

Kyodo also reports that Naoto Kan ordered TEPCO not to pull employees out of the Fukushima plant.


The Japanese nuclear safety agency says there are two eight-metre holes in the wall of Fukushima no.4 outer building after the blast there.

Holes in wall mean spent nuclear fuel pool at No.4 reactor is exposed to outside air: TEPCO


Spend Fuel Pools at reactor 5 and 6 are at around 84° celisus, according to TEPCO and NHK. Normal temperature is 40

Reactors 4, 5, and 6 were all down for maintenance at time of quake, but all 3 suffered cut-off of water circulation in their spent fuel ponds. The problems at No. 4 are more acute because all of its fuel rods are in the pool while 5-6 have only 1/3 as many fuel rods. But temps slowly rising at 5-6 also.

Kyodo is reporting that TEPCO has become unable to pour water onto the spent fuel in reactor 4.

Failure to keep adequate water levels in a pool would lead to a catastrophic fire, said nuclear experts, some of whom think that unit 1’s pool may now be outside.

“That would be like Chernobyl on steroids,” said Arnie Gundersen, a nuclear engineer at Fairewinds Associates and a member of the public oversight panel for the Vermont Yankee nuclear plant, which is identical to the Fukushima Daiichi unit 1.

People familiar with the plant said there are seven spent fuel pools at Fukushima Daiichi, many of them densely packed.

    Excellent. this pleases me to see everything spelled out like this.

    I've been reading a lot of what happens on Abovetopsecret.com but when explaining this situation to the ignorant, I will be using this list.

    Also I believe reactor #4 was using MOX fuel, which is several times more powerful than enriched uranium. i don't have my source on that anymore though, google it.

    My stepson was speaking with a guy who is a specialized contractor on reactors who has actually worked on the plants. He indicated that the reason the hydrogen exploded was due to venting apparatus that was damaged in the earthquake/tsunami. Do to this being damaged the hydrogen could not be vented and exploded due to the pressure.

    Pressure drop, you say?

    Well I have lots of Fallout practice.
    I kinda hope this shit will just get worse and kill cosplayfags or Weaboos in the process. I feel sorry for the Japanese people as they are nothing but honest, reserved, good-natured people, but are let down by the way the West interprets their culture.

    In short, people like this would be who I would use to cool the reactors down:

    Yes, but the H2 formed because the water is oxidizing the metal in the reactors. Not good...

    Latest news:

    *Pilots returning from humanitarian missions being treated for radiation sickness.

    *Explosion at reactor number 4 claims 5 lives and releases 400 foot plume of radioactive smoke and particulate.

    * Radioactivity released directly into the atmosphere has dramatically spiked in levels.

    * Level 6 emergency (Chernobyl was a 7) 50 workers are left at the plant when a normal operating staff required to maintain the reactors safely is 600 or more.

    * The Japanese government is considering using military helicopters to drop water onto the spent fuel pools.

    * spent fuel pool at Reactor 4 has no water, radiation levels are "extremely high"


    Status as of now:
    S540L.jpg


    For those that don't know what a meltdown is: The fuel melts and then burns through the bottom of the reactor, and it just keep going giving off radioactive smoke, in the process. Concrete burns, and it can theoretically keep burning into the Earth until it reaches the water table.

    It getting down into the water table is not so much of a problem - the water table in japan does not directly link to the water table in other coutries, as it has the sea seperating it.

    Now, while it is not good that a lot of shit would end up in the sea if the bad stuff was transported by water, the sea would soak it up and it would fall away to hidden deapths, out of sight, out of mind.

    It is the fire we need worry about, that is the thing that would quickly spread fuckloads of bad radiation very quickly - the smoke coming frome the fire would contain reactor products and nuclear fuels.

    Not a good day when it rains that shit down on you.


    Unless they get this under control soon, some place, hundreds, maybe even thousands of miles from the reactor will be facing nuclear rain within a couple of days to a week.

    What does this mean to you?

    Well the US is in very little danger, if anyone's fukd its japan.

    Ceasium-137 and Strontium-90 tend to stay within miles of the plant.
    Iodine-131 has a very short half life.

    There doesn't seem to be any hope for getting these reactors under control, and I don't think they can dump water on #4's waste pool because it may be spewing way too much gamma radiation vertically. :-/

    Latest news:

    * Helicopters are rotating in their mission to dump water on Reactor 3, gathering seawater from close to the Fukushima Daiichi plant. Four water drops are so far thought to have taken place but targeting of the spray is proving difficult A lead plate is attached to the bottom of each chopper and the crew are wearing protective suits.

    * They cannot drop water on #4's pool due to a roof being in the way.

    Thanks totse for explaining it in rather excellent detail.

    Also I was told the reason all these problems started was because the plant was designed to take the highest flood they had ever had which was 8M instead they got 30M..
  • KatzenklavierKatzenklavier Regular

    The problems started because the plant lost power and they could not cool the reactors (pumps need power). All 3 (4?) redundant backup systems failed.

    Source
    (Reuters) - The Fukushima Daiichi nuclear power plant at the center of Japan's crisis has six reactors. The plant is operated by Tokyo Electric Power Co (TEPCO).

    The following summarizes what is happening at each unit, and the major risks:

    WHICH REACTORS ARE MOST AT RISK?

    REACTOR No 3: 784-MW (Manufacturer Toshiba)

    -- What is happening:

    Helicopters and trucks were used to water down reactors as authorities reiterated on Thursday that resolving problems at the plant -- the only unit to include plutonium in its fuel mix -- was the priority.

    White smoke coming from the plant could be steam evaporating from the spent fuel pool, the Japan nuclear agency said on Thursday. It said pressure in the reactor was rising again.

    Radiation readings at the reactor are the highest at the Daiichi complex, TEPCO said on Wednesday.

    There was an explosion at reactor 3 on Monday.

    -- What are the risks:

    The major concern is that any steam coming from the plant will carry radiation into the atmosphere. It's not clear where this could be coming from.

    Chief Cabinet Minister Yukio Edano said on Wednesday there is a "possibility" the primary containment vessel, the first line of defense against a radiation leak, had been damaged, Kyodo reported. The reactors also have a secondary containment building. (see below: CONTAINMENT -- WHAT IS IT?)

    However, the Japan nuclear agency noted the steam could be coming from the spent fuel pool. That would indicate that water covering the spent fuel is evaporating, which in turn could mean the vapor is carrying off radiation.

    The spent fuel pool presents a significant radiation risk if its contents are exposed to the atmosphere. When fuel rods are exposed to the air, zirconium metal on the rods will catch fire, which could release radiation contained in the fuel, said Arnie Gundersen, a 29-year veteran of the nuclear industry who is now chief engineer at Fairwinds Associates Inc.

    Plutonium is considered more hazardous than uranium

    REACTOR No 4: 784-MW (Manufacturer Hitachi)

    -- What is happening:

    There is no water in the spent fuel pool and radiation levels are extremely high, the chairman of the U.S. Nuclear Regulatory Commission said in Washington on Wednesday.

    However, TEPCO said on Thursday that as of Wednesday the spent fuel pool still had water in it.

    TV on Wednesday showed smoke or steam rising from the facility after flames were seen earlier in the day. The reactor had been shut down for maintenance when the earthquake and tsunami struck.

    On Tuesday, the spent fuel pool caught fire and caused an explosion. Japan's nuclear safety agency says the blast punctured two holes around 8-metres square in the wall of the outer building of the reactor.

    -- What are the risks:

    Exposure of spent fuel to the atmosphere is serious because there is more radiation in the spent fuel than in the reactor, said Gundersen. The spent fuel pool is not inside a containment facility either.

    "They need to keep water in those pools because the roof over the building housing the pools is already damaged and radiation will escape," he said.

    The pools contain racks that hold spent fuel taken from the reactor. Operators need to constantly add water to the pool to keep the fuel submerged so that radiation cannot escape.

    Exposing the spent fuel to the atmosphere will release radiation.

    REACTOR No 2: 784-MW (Manufacturer: GE, Toshiba)

    -- What is happening:

    TEPCO plans to run a cable to reactors No 1 and No 2 to try to restore power to the water cooling system, the Japan nuclear agency said on Thursday.

    An explosion rocked the plant on Tuesday, damaging a suppression pool, into which steam is vented from the reactor to relieve pressure. The roof of the reactor building is damaged, Jiji news agency reported.

    TEPCO said on Tuesday the fuel rods were fully exposed. An estimated 33 percent of the nuclear fuel rods have been damaged at the No 2 reactor, Kyodo quoted TEPCO as saying on Wednesday.

    However, on Wednesday, Japan's nuclear agency said the pumping of sea water into the reactor was proceeding smoothly.

    -- What are the risks:

    When fuel rods are no longer covered in coolant they can heat up and start to melt, raising the risk of a radiation leak and in a worst-case scenario a full meltdown.

    The suppression pool is part of the primary containment vessel, which is designed to prevent a leak, but the IAEA said the blast "may have affected the integrity of its primary containment vessel."

    Still, beyond the primary containment vessel is the containment building, which is also designed to prevent radiation from escaping.

    REACTOR No 1: 460-MW (Manufacturer GE)

    -- What is happening:

    Japan's nuclear safety agency said on Thursday the reactor, along with units No 5 and No 6, was relatively stable for now.

    Earlier on Thursday, it said that TEPCO planned to run a cable to reactors No 1 and No 2 to try to restore power to the water cooling system.

    An explosion occurred at the reactor on Saturday. Kyodo quoted TEPCO as saying on Wednesday that an estimated 70 percent of the nuclear fuel rods have been damaged.

    The Japan nuclear agency said on Wednesday the pumping of sea water into the reactor was proceeding smoothly.

    -- What are the risks:

    The IAEA said on Tuesday the primary containment vessel appeared intact. If the fuel rods in the reactor are not covered by coolant, they can heat up and start to melt.

    REACTOR No 5: 784-MW (Manufacturer Toshiba)

    -- What is happening:

    The reactor is now being powered by a diesel generator shared with unit No 6.

    The reactor had been shut down for maintenance at the time of the quake and tsunami.

    TEPCO said on Wednesday water was being poured into the reactor and that temperatures in the spent fuel pool were rising slightly.

    -- What is the risk:

    Reactor 5 and reactor 6 are seen less at risk than reactors 1 to 4.

    REACTOR No 6: 1,100-MW (Manufacturer GE, Toshiba)

    -- What is happening:

    The reactor is now being powered by a diesel generator shared with unit No 5.

    TEPCO said on Wednesday water was being poured into the reactor and that temperatures in the spent fuel pool were rising slightly.

    -- What is the risk:

    Reactor 5 and reactor 6 are seen less at risk than reactors 1 to 4.

    WHAT ARE THE RADIATION LEVELS, WIND DIRECTION?

    -- Radiation levels were higher than normal but not dangerous, Japan's Nuclear and Industrial Safety Agency said on Thursday.

    -- They were measured at 338 microsieverts per hour at the west gate at 2000 GMT March 16 (5 am local time March 17). If a person stands outdoors for a year, they would be exposed to a radiation level of 400 microsieverts, the agency said.

    -- The wind is blowing northwest-to-southeast, toward the Pacific Ocean, Japan Meteorological Agency said.

    CONTAINMENT -- WHAT IS IT?

    Each reactor is surrounded by a primary containment vessel. This is made of strengthened steel four-to-eight inches thick. It provides the most critical line of defense against leaking radiation from the reactor.

    Should there be a breach, there is another, final line of defense to prevent radiation leaks: a bigger containment building made of steel and concrete. A breach of the containment building would release radiation into the atmosphere.

    So, reactor #3 had its fuel melt through the vessel and reactor #1 went critical...

    'Suicide squads' paid huge sums amid fresh fears for nuclear site

    By David McNeill in Tokyo
    The Independent
    Wednesday, 30 March 2011

    The radioactive core in one reactor at Fukushima's beleaguered nuclear power plant appeared to have melted through the bottom of its containment vessel, an expert warned yesterday, sparking fears that workers would not be able to save the reactor and that radioactive gases could soon be released into the atmosphere.

    Richard Lahey, who was a head of reactor safety research at General Electric when the company installed the units at Fukushima, said the workers, who have been pumping water into the three reactors in an attempt to keep the fuel rods from melting, had effectively lost their battle. "The core has melted through the bottom of the pressure vessel in unit two, and at least some of it is down on the floor of the drywell," he said.

    The damning analysis came as it emerged that workers at Japan's stricken nuclear plant are reportedly being offered huge sums to brave high radiation in an attempt to bring its overheated reactors under control. The plant's operator, the Tokyo Electric Power Company, is hoping to stop a spreading contamination crisis which could see another 130,000 people forced to leave their homes.

    Radiation has already found its way into milk, vegetables and tap-water and is leaking into the sea around the complex. Government tests found yesterday that small quantities of plutonium, one of the world's most dangerous elements, have seeped into soil outside the plant.

    State broadcaster NHK said underground tunnels linked to reactors 1, 2 and 3 are flooded with water containing radiation measured in some spots at a highly dangerous 1,000 millisieverts an hour. Workers in protective gear are shoring up the tunnel shafts with sandbags to stop the water – which reportedly contains concentrations of long-lived caesium-137 – from seeping into the sea about 55 to 70 metres away.

    Japan's Nuclear Safety Agency said that the plutonium was "not at levels harmful to human health", but the government's top spokesman Yukio Edano called the situation "very grave", and confirmed fears that at least one reactor had suffered a partial meltdown.

    The admission added to pressure on Prime Minister Naoto Kan to widen an exclusion zone around the plant, possibly forcing another 130,000 people to evacuate. Yesterday, a tired-looking Mr Kan faced withering criticism from opposition MPs, who called him "irresponsible" and "incompetent".

    Engineers at the Fukushima Daiichi complex struggling to restart cooling systems for reactors are being hampered by the radiation and lack of electricity, forcing them to work in the dark and regularly withdraw.

    Subcontractors to several companies connected to the plant have reportedly been offered 80,000 to 100,000 yen a day (£608 to £760) to join the operation, according to one former plant worker. The team of men inside the complex have been dubbed "samurai" and "suicide squads" in the popular press.

    "Do I trust Katz more than the media?, fucking hell yeah"

    A post came through as I was writing this. And it brings up a question, do the Japanese reactors use metallic uranium or uranium oxide? And how hot does it have to get for uranium oxide to lose the oxygen and start melting? Does the uranium have the potential to enrich the uranium around it and produce fast fission capable uranium, or even plutonium? Fuck, this is sooo going to help the anti nuclear lobby groups.

    I dont think its a long term thing, building up levels of iodine in the body to help prevent an uptake of radioactive iodine, more of a take a big hit to fill you up. Looked for some research into it and this is what I found:

    http://www.ncbi.nlm.nih.gov/pubmed/1759381
    A comparative evaluation of the body uptake of iodine in ionic and molecular forms in vaginal irrigations with iodide-bromide water (experimental research)

    Can you imagine recruiting subjects for that? Hi there, how would you like to have a solution of chemicals injected in your Mary?

    They use uranium oxide. Everyone stopped using flammable uranium metal after http://en.wikipedia.org/wiki/Windscale_fire

    However reactor 3 uses MOX (mixed oxide fuel), and that contains plutonium as well as uranium. Plutonium is much more active than uranium so it poses a greater threat were it to escape. Escaped uranium is meh, not too bad really. The decay products are the real danger, they are extremely active since they have short half lives.

    Reactor 3 is presumably the one that melted, but the damn japs keep trying to stifle the information so I'm not positive.


    A week ago 3 workers suffered severe radiation burns when water leaked in their suits. This leads me to believe that the fuel casings have cracked open and the water is making direct contact with the fuel, picking up some of the decay products on the way.
