This is a timeline of the continuing Fukushima Nuclear Crisis. This part covers some history and a day-by-day account of the first 2 months of the crisis, pasting together all of the disparate sources. The editor believes that the crisis is not going to kill millions of people, but it is affecting most Japanese as even Tokyo is getting alarming if not yet definitely harmful levels of radioactive contamination, and hundreds of thousands have evacuated and lost their jobs and homes even if the official number of deaths attributed to radiation is zero, and the worst possible extrapolation including deceptive "acute lukemia" diagnoses and suicides is not worse than the small hundreds compared to the tens of thousands who drowned in the tsunami.

In 1952, General Electric staked its claim on the nuclear future with this promotional film to calm nuclearfears. It fortold that nuclear power would be useful for power stations (with a PWR diagram, they would eventually settle on BWR) locomotives, ships and even aircraft, and illustrated atomic transmutation as badly behaved citizens in a town of nuclear atoms. GE didn't start its reactor business until 1955.

The General Dynamics prop powered NB-36 tested flying around with a nuclear power plant which would power jets. See Nuclear Bombers In 1961, there were articles about a jet powered B-52 class NX-2. On landing, the reactor would be removed and put in to a pool, while the crew would go into a specially shielded vehicle to drive away from the bomber. B-52s worked just fine to get all around the planet with in-flight refueling with KC-135 tankers, and still do today.

Nikolai Vladimirovich Zateyev, commander of the submarine at the time of the nuclear accident

On 4 July 1961, under the command of Captain First Rank Nikolai Vladimirovich Zateyev, K-19 was conducting exercises in the North Atlantic close to Southern Greenland when it developed a major leak in its reactor coolant system, causing the water pressure in the aft reactor to drop to zero and causing failure of the coolant pumps. A separate accident had disabled the long-range radio system, so they could not contact Moscow. The reactor temperature rose uncontrollably, reaching 800 °C (1,470 °F) — almost the melting point of the fuel rods — and the chain reactions continued despite the control rods being inserted via a SCRAM mechanism. The reactor continued to heat up as coolant is still required during shutdown until the reactions decrease. Despite Zateyev's and others' earlier requests, no backup cooling system had been installed.

As a cooling back-up system had not been installed, Zateyev made a drastic decision; a team of seven engineering officers and crew worked for extended periods in high-radiation areas to implement a new coolant system by cutting off an air vent valve and welding a water-supplying pipe into it. Since the ship carried chemical suits, instead of radiation suits (not available at the time and developed after accidents like this), they were certain to be lethally contaminated,[citation needed] but the repair team was unaware of the degree of risk, believing the suits they wore would protect them from contamination. The released radioactive steam, containing fission products, was drawn into the ventilation system and spread to other sections of the ship. The cooling water pumped from the reactor section worked well.

The incident contaminated the crew, parts of the ship, and some of the ballistic missiles carried on board; the entire crew received substantial doses of radiation, and all seven men in the repair crew died of radiation exposure within a week, and twenty more within the next few years. The captain decided to head south to meet diesel submarines expected to be there, instead of continuing on the mission's planned route. Worries about a potential crew mutiny prompted Zateyev to have all small arms thrown overboard except for five pistols distributed to his most trusted officers. A diesel submarine, S-270, picked up K-19's low-power distress transmissions and joined up with it.

Deborah Lutterbeck reports GE wholly built one of the six reactors at the Fukushima Daiichi power plant that has been in a state of crisis since being hit by a massive earthquake and tsunami last week, and it built two others jointly with Toshiba Corp. Toshiba built two on its own and Hitachi Ltd built one The design of the GE-built reactor, and particularly the Mark I containment unit that is supposedly designed to ensure that radioactive material did not escape, has drawn criticism. One unusual characteristic of the Fukushima facility involves the spent fuel pools -- where fuel rods are held to cool down after they are moved from the reactor but before they are sent to long-term storage. At the Fukushima site, the fuel pools stand over the the reactors, which means there is a possibility they can spill radioactive material onto the reactors if there is a major accident, one expert said....."It's the only reactor built in that way that I know of. It was a poor decision and we are living with the results of that poor decision. It's a really odd design." Former GE engineer David Bridenbaugh, who resigned 35 years ago over concerns that the containment system was not strong enough, this week told reporters it had "not been designed to withstand the loads" of a large-scale accident. ...earthquake and tsunami went beyond the risks engineers had anticipated. The GE-Hitachi nuclear joint venture generates about $1 billion in annual revenue through maintenance on existing plants and fuel sales. GE has not built a new nuclear power plant in more than a decade --

Tepco admitted covering up data about cracks in critical circulation pipes. In their analysis of the cover-up, The Citizen's Nuclear Information Centre writes: "The records that were covered up had to do with cracks in parts of the reactor known as recirculation pipes. These pipes are there to siphon off heat from the reactor. If these pipes were to fracture, it would result in a serious accident in which coolant leaks out.

The Kashiwazaki-Kariwa Nuclear Power Plant was shut down for 21 months afre the July 2007 6.6 earthquake which shook the plant beyond design basis (never mind the 9.0 earthquake that hit fukushima)

From Wikipedia, the free encyclopedia

The Kashiwazaki-Kariwa Nuclear Power Plant is a large, modern (housing the world's first ABWR) nuclear power plant on a 4.2-square-kilometer (1,038 acres) site[1] including land in the towns of Kashiwazaki and Kariwa in Niigata Prefecture, Japan on the coast of the Sea of Japan, from where it gets cooling water. The plant is owned and operated by The Tokyo Electric Power Company (TEPCO).

It is the largest nuclear generating station in the world by net electrical power rating. It was approximately 15 miles from the epicenter of the second strongest earthquake to ever occur at a nuclear plant, the Mw 6.6 July 2007 Ch?etsu offshore earthquake. This shook the plant beyond design basis and initiated an extended shutdown for inspection, which indicated that greater earthquake-proofing was needed before operation could be resumed.

The plant was completely shut down for 21 months following the earthquake. On May 9, 2009, one unit (Unit 7) was restarted, after seismic upgrades. Units 6, 1, and 5 have since been restarted as well.

No explosion at No. 2 reactor / TEPCO: Only 3 hydrogen blasts occurred at Fukushima N-plant The Yomiuri Shimbun

In the spring of 2008, TEPCO estimated that a 15.7-meter tsunami could hit the Fukushima No. 1 nuclear power plant in the future, which was about the size of the March 11 tsunami.

The utility came up with another estimate in December that year, modeled on the Jogan tsunami that hit northern Japan in 869. This estimate was 9.2 meters.

Deconstructing the zero-risk mindset: The lessons and future responsibilities for a post-Fukushima nuclear Japan Tatsujiro Suzuki

In June 2009, when a working group met to discuss earthquake and tsunami risks, Yukinobu Okamura, a government researcher, said, “I cannot accept this report because it does not mention it [Jogan earthquake and tsunami] at all, [even though] it hit the Tohoku area in 869 with huge impact” (Joint Working Group on Earthquake/Tsunami, 2009, emphasis added). The researcher was complaining that the new report by the advisory committee—of which he was a member—did not thoroughly consider the Jogan tsunami. Further, Katsuhiko Ishibashi, a former member of an advisory committee for the Nuclear Safety Commission—which advises the prime minister, oversees NISA’s activities, and establishes basic safety guidelines—also expressed similar warnings in a paper published in Science in 1997: “For nuclear power plants, a disaster caused by an earthquake can be especially dangerous because it could cause multiple failures at the same time, unlike a normal accident” (Ishibashi, 1997: 723, emphasis added).

A 10km long traffic jam had clogged the main road west out of Fukushima towards Niigata as residents fled the nuclear disaster. The prefecture government had become aware of the mass exodus the previous afternoon. Their 14 member team began setting up locations where evacuees could rest, consult with officials and be tested for radiation. TEPCO press release

divvy (547 posts) Thu Mar-17-11 05:45 3-12-11 #1 It very well could be the worst nuclear disaster ever... it would be impossible to prevent the fuel failure of a plant after a design basis earthquake and a tsunami loss of all offside power and all of the emergency generators, if that is what has happened. There is not likely enough batteries to last more than 4-8 hours... and little pumping capacity even then. This would be the first time that multiple reactors (3) would be lost at one site. Both TMI and Chernobyl only involved the loss of 1 unit at a site. The big unknown in my mind is what is the status of the spent fuel pools. I haven't heard whether these are PWRs or BWRs... That would say a lot about he spent fuel pool configuration. If the spent fuel pools are not cooled and an adequate water coverage maintained, the danger is off the map
The hydrogen explosion that has destroyed one containment building could very well be from "melting" fuel cladding,.. offsite power... No emergency generators... No containment... Expanding evacuation zone... I'm worried! .. they lack the ability to take the reactor(s) to shutdown. Low pressure injection has probably been lost. .. report that they were injecting sea water into the containment means that normal emergency systems have failed and the situation is pretty desperate. The other 2 plants? Fuel pools?

The fuel pools are probably OK, because they could keep them full with a fire truck tanker... As long as radiation levels onsite stay reasonably low. I don't think any plants, but the most recent designs, would do well after control rooms become uninhabitable. The collapsed reactor building probably eliminated most, if not all, remaining capabilities of that stricken reactor. If it was a sub, you would get out and sink it. Not good...

When I was a young, rookie engineer, a mentor told me about the hidden terror in the fuel pool. He said to me that if a crane operator latched onto a fuel bundle and hit the UP button (there are interlocks to prevent that), by the time the top of the bundle reached the surface, everyone on the refuel floor would be dead... nobody would make it off the floor. There are hundreds of bundles in the pool. I don't know if this story is true, but I never had any reason to doubt it. Hydrogen burning will accellerate the loss of water in the pool. The pool liner and structure can't handle fuel meltdowns. Once the 1/4" or so stainless steel liner is breached, the pool will never hold water again. Hydrogen explosions could be devastating in spreading radioactove material, a hazard worse than just radiation "shine." It may look a lot like explosions to the lay person. I would rather see a core meltdown than an empty fuel pool. I think we are looking at something similar to Chernobyl. Hopefully, less devastating in loss of life... but something that may be even harder to control. I am not sure how long we have to turn this around... maybe a couple days... maybe not. I'm not smart enough to caculate the answer, but there are people that are. Chang, the amount of radioactive materials in these pools is many multiples of what was in Chernobyl. As the water level lowers, you are going to have steam "explosions", hydrogen burning and explosions... there are calculations to calculate Keff for each bundle to insure that no bundle can go critical, even in localized areas... how good do you think those calculations are now, Chang. I don't know how bad it will be, but I am not so certain that it won't be aweful. Will the whole pool meltdown? No, but it doesn't have to to still be very bad. Once the pool is filled and cooled, the water needs to be cleaned up. It is probable very acidic right now... very corrosive.
The worst case I see is the fuel overheating and melting its way into the earth. It would contaminate groundwater and air. Once they decide this is inevitable, they should be using drilling equipment equipped with liquid nitrogen to freeze the ground around the meltdown sites (the way they do to construct tunnels in soft soil), combined with lots of concrete, to entomb the site as Chernobyl was. Atmospheric contamination is bad, but will disperse quickly.
What you don't have here is a nuclear explosion like Chernobyl, which spread fission products over thousands of square miles, contaminating crops and livestock. If the cores burn their way down to the center of the earth, so be it. I think our focus then is on ring fencing the underground contamination, using drilling and concrete.

Day 3: Unit 3 cooling fails, melts down, hydrogen is building up, Unit 4 pool heading towards boiling, "no meltdown"

No time:

http://allthingsnuclear.org/post/3842650618/sunday-update-on-fukushima-reactorsTokyo Electric reported that after multiple cooling system failures, the water level in the Unit 3 reactor vessel dropped 3 meters (nearly 10 feet), uncovering approximately 90 percent of the fuel in the reactor core. Authorities were able to inject cooling water with a fire pump after reducing the containment pressure by a controlled venting of radioactive gas. As they did with Unit 1, they began pumping sea water into Unit 3, which is highly corrosive and may preclude any future use of the reactor even if a crisis is averted.However, Tokyo Electric has reported that the water level in the Unit 3 reactor still remains more than 2 meters (6 feet) below the top of the fuel, exposing about half the fuel to air, and they believe that water may be leaking from the reactor vessel. When the fuel is exposed to air it eventually overheats and suffers damage.

  • A report written at 2:07 p.m. also stated there was a strong possibility that hydrogen had accumulated in the No. 3 reactor building. The documents indicate hydrogen was being produced because the fuel rods were exposed to air after the earthquake and tsunami destroyed the cooling system. However, TEPCO did not report these findings to NISA or local governments. http://www.asahi.com/english/TKY201106250160.html

At this point, we don’t have any indication of the damage done to Unit 3 reactor, but utility/govt officials are claiming the reactor vessel was not damaged. As for the building housing the reactor, before/after images captured by Jim White indicate this latest explosion blew the roof and walls off the reactor building. See below.

What emerged that we didn't know was that there had also been an explosion and a fire in reactor 4 at Fukushima. Number 4 had an explosion as well and then a fire which is what was revealed in that press conference. Yes, number 4 was not in operation at the time of the earthquake. There were no active fuel rods in there but there is spent fuel.

Fire confirmed Japan Earthquake Update (15 March 2011, 06:15 CET) Japanese authorities informed the IAEA that there has been an explosion at the Unit 2 reactor at the Fukushima Daiichi plant. The explosion occurred at around 06:20 on 15 March local Japan time. Japanese authorities also today informed the IAEA at 04:50 CET that the spent fuel storage pond at the Unit 4 reactor of the Fukushima Daiichi nuclear power plant is on fire and radioactivity is being released directly into the atmosphere. Dose rates of up to 400 millisievert per hour have been reported at the site. The Japanese authorities are saying that there is a possibility that the fire was caused by a hydrogen explosion.

    divvy (547 posts) Tue Mar-15-11 07:13 PM explosions are not good Reports of explosions are not good... No kidding. The zircolloy reaction of clad melting gives off a lot of hydrogen, which can accumulate in the top of the reactor vessel. Such a bubble of explosive gasses is very dangerous. Large scale fuel failure is probably happening at multiple plants. My guess is that the explosions are from hydrogen vented from the vessel. That is a sign of fuel clad "melting." Core melting doesn't necessarily mean that the worst case scenario will result... It didn't at TMI. As long as they can prevent reactor vessel failure, the impact on the general public can be minimized. I know the GE Mark I plant had design provisions for pumping seawater into the reactor... I don't know if the other plant designs did. I haven't heard what resources are being brought in to help plant personnel. They need help... Not just advice! What is being done to restore power to these stricken plants? ... And when will they have it? No plant, even one originally in cold shutdown, can operate indefinitely without AC power. I guess I am frustrated to hear of casualties... People can't go into primary containment under these circumstances. Venting should be to primary containment, which could then be vented through a standby gas treatment system in the RX building, if there is AC power to run it. That could be where the hydrogen explosion occurred. The system has a heater that wouldn't be good with an explosive mix of hydrogen. PWRs actually have glow plugs or some type of heaters to burn hydrogen inside their much larger containments. BWRs don't have these systems. The Mark I containment could not accommodate open flames... too small.
