Is "Timeline of the Fukushima nuclear accidents" really appropriate? Daiichi is in the introduction as being covered by this article, but Daini also had incidents at that plant. If this article covers both nuclear power plants, then the title is fine, if it only covers Fukushima I, then it should be renamed Timeline of the Fukushima I nuclear accidents. 184.144.160.156 ( talk) 12:30, 14 March 2011 (UTC)
If this only covers only plant 1, then should it exist separately from Fukushima I nuclear accidents ? (see Talk:Fukushima I nuclear accidents for the status of that article)
The intro paragraph clearly links only to Daiichi, and not to Daini.

There are lots of times that are the time that someone told the media what hapend, and not the time the actual event hapend. What is interesting in a time line is the actual events time if it is avaible. —Preceding unsigned comment added by 195.67.14.129 ( talk) 12:51, 14 March 2011 (UTC)
I would like to say that the two tables for conditions on March 14th have been very informative for establishing what is currently going on. Is there any chance that with the recent developments that the table could be updated, or perhaps a new table made for the current status? —Preceding unsigned comment added by 141.210.86.74 ( talk) 00:03, 15 March 2011 (UTC)
There's a big problem with one of the Fukushima I images. File:Japanese second explosion.png is on commons, claims to have been screencap'd off CTV Winnipeg, a commercial TV station, but also claims to be GFDL. This is clearly impossible. The screenshot itself has a credit for NTV Japan, annother commercial TV station.
I suggest this be uploaded to Wikipedia with the copyright status corrected, and fair-use rationales created for the pages on which it would appear. 184.144.160.156 ( talk) 01:54, 15 March 2011 (UTC)

Looking at this article, I wonder if there is some confusion between Reactor #2 and #4, because the article states that #4 had an explosion and fire, while everything else points to damage having occurred at #2. I guess it might just pay to keep an eye on this one. http://uk.reuters.com/article/2011/03/15/japan-quake-snapshot-idUKL3E7ED02D20110315 72.66.232.117 ( talk) 03:25, 15 March 2011 (UTC)Michael Rudmin
The BBC translated the presidents speech as stating Reactor Number Four was on fire. It seemed odd to me also but it could be damage from the explosion from Reactor Number Two, I think we should wait for more information and sources before adding it to the article 94.168.210.8 ( talk) 03:45, 15 March 2011 (UTC)
Table in section regarding Tuesday 15 March has been vandalized. Recommend locking article? SnowmanRequiem ( talk) —Preceding undated comment added 03:15, 15 March 2011 (UTC).
Reactors 5 and 6 were shut down prior to the earthquake. But their fuel load remains in the core, and still needs cooling, just as the spent fuel. The longer the reactor is shut down, they need less and less cooling, but it's several years until they'd need no cooling at all. The wording "not neccessary" implies exactly that (no cooling at all), and that's wrong for sure. —Preceding unsigned comment added by 141.52.149.147 ( talk) 14:50, 16 March 2011 (UTC)

With Siverts being a si unit when it reaches "1000 micro Sieverts", isn't that then "1 sievert". If so I think this,
"Environmental effect 11,900 microSievert/hour at 09:10"
should read 11.9 Sievert/hour instead of 11,900 microSievert/hour
this would provide better understanding for people looking at

The table states Fukushuma 1 Unit 1 at 20:30 on March 14 and 0700 on March 15, for "Pressure vessel, water level:" "None." This seems to be stating that there is no water whatever in that reactor core, which is a dire situation which would lead to a complete meltdown. Is it supposed to mean that we have "no status information," and if it really means the fuel rods are completely exposed, a source is needed. Edison ( talk) 15:18, 15 March 2011 (UTC)

Should there be an article relating rad, rem, roentgen, curie, gray, sievert, rutherford, becquerel ? We don't seem to have an overarching article to cover the differences between these units. As older disasters did not use sieverts (Three Mile Island, Chernobyl) in news broadcasts from that period, people looking up resources on those events may end up needing some sort of guide on the issue. 184.144.160.156 ( talk) 12:17, 16 March 2011 (UTC)

1 Sv / Sievert / = 100 Roentgen / biological Roentgen /
1 microSievert / h μSv= 100 micro-Roentgen per hour
1 000 000 = 10 -6 degree microRoentgen per hour = 1 Roentgen per hour
Normal level of radiation 0.20 mikroSievert / h = 20 microRoentgen per hour,
1 Gray = 1 Sievert
1 Gray = 100 Roentgen / Rad on the scientific /
1 BER = 1 Roentgen
1Rad = 1 Roentgen / Röntgen in the original in German /
1 Rem = 1 Roentgen
Lethal dose is about -600 Roentgen / Rad on the scientific /= 6 Sievert All dramatically simplified
Becquerel Never translate into Roentgen
-Becquerel and Curui is that you had get fallen on his head / background / -Roentgen something that you become inside during particular PERIOD of TIME before you leave an infected area.
Acute radiation sickness
In practice, almost never determined by the dose that you have received, it is very difficult to measure the total your dose. ALWAYS determined by the symptoms, particularly in terms of decrease of lymphocytes, white blood cells / on what day and what per cent./

...Kyodo News reported that radiation had risen to 8.2 millisieverts per hour[98] around two hours after the explosion—about four times what one usually is exposed to within a whole year.... The article currently states a rate (8.2 mSv/hour) can be a multiple of (four times) a total accumulation (exposure accumulated after a year, no units given) and then later drop to an accumulation (2.4 mSv). Such is not possible. The statement ought to be either rewritten in terms that make sense or eliminated as being of no value.
To clarify: Please note this is not an issue with magnitudes of units (micro vs. milli).
This is an issue of mSv/hr versus mSv versus mSv again.—Preceding unsigned comment added by 69.112.194.203 ( talk) 22:20, 15 March 2011 (UTC)

Hi! I am the initiator (69.112.194.203) of this topic and it was I who appended "To clarify: Please note this is not an issue with magnitudes of units (micro vs. milli). This is an issue of mSv/hr versus mSv versus mSv again." My apologies for not knowing, at the time, how to sign it. I have cleared that up, now (see above). This discussion on units is scrambled beyond my ability to follow but none of it is pertinent. There remains an issue, not with units so much as with an incorrect comparison between a dose and a dose rate. It's now in the section for Tuesday 15 March, 06:14 where it talks in "microsieverts per hour" (a dose rate) and then states, "That is about eight times a normal annual exposure" (a dose). A dose rate multiplied by eight does not equal a dose. One possible edit would say, "The radiation dose rate later fluctuated up to 8,217 microsieverts per hour, two hours after the explosion. That would result, in one hour, in a dose about eight times the normal annual dose." I cannot make that edit however because I do not know if the resulting statement would be true. I am also unable to locate the original source material. Since the text as it stood was not logical, regardless of its source, I have simply removed the incorrect comparison to accumulated annual dose. I stand by to see how this is received. Many thanks.

This is misinformation. CNN actually reported on air that it is a 10km evactuation radius around Daini, not 3 or 6. and if you have been paying attention to NHK-G or NHK World this 10km evactuation around Daini has been since the second day of this, it was declared at the same time Daiichi was increased to 10km. But CNN is just noticing this. Currently according to NHK it is 10km evactuation around Daini and 20km evactuation arund Daiichi with 30km to stay indoors.

This reference to a central spent fuel pool in the introductory paragraph seems to have been added on 2 April. Nothing else about a central spent fuel pool is mentioned in the article. In the separate article "Fukushima 1 nuclear accidents", the central fuel storage pool is mentioned, but that article indicates everything was OK there on 28 March. Everything I have read and viewed about the power plant, and GE boiling water reactors in general, indicates that each reactor has its own spent fuel pond high up in the reactor building. These individual pools are where all the problems I have read about are happening. If the central pool is also having a problem this needs clarification.
Very good article otherwise, and one of the best sources of info on the Web.

Common Spent Fuel Storage Facility: The Common Spent Fuel Pool temperature is stable. TEPCO tested an “anti-scattering” agent (2000 l) on 500 m2 area around the Common Spent Fuel Storage facility on 1st April. The purpose of spraying is to prevent radioactive particles from being dispersed from the plant by winds and rain.
why call it the 'Central Spent Fuel Pool' when all references to it by tepco and the iaea use the term 'Common Spent Fuel Pool'? There are references to the area on the IAEA's daily summaries for 18th, 20th 21st 22nd 23rd 24th and 25th March along with rising temperature readings - in addition Tepco's report of the 23 march mentions 2 workers injured at the common spent fuel pool on 22nd at 10pm and 23rd at 1am. As the common spent fuel pool holds the vast majority of the fuel rods stored at Fukushima Daiichi it may become an issue that gains increasing importance as events unfold. 81.111.39.70 ( talk) 14:11, 3 April 2011 (UTC)

"On 30 March, NISA said that air may be leaking from the Reactor Pressure Vessels of Units 2 and 3 because some of their data show the pressure in the vessels is low, but there is no indication of large cracks or holes in the vessels."
"Air is the name given to atmosphere used in breathing and photosynthesis. Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. While air content and atmospheric pressure varies at different layers, air suitable for the survival of terrestrial plants and terrestrial animals is currently known only to be found in Earth's troposphere and artificial atmospheres." - Wikipedia
Air is not found in Reactor Pressure Vessels. Any gas escaping will be mainly Xenon hopefully 131 from decayed Iodine-131.

We should probably defer to whatever decision is concluded in the main discussion. You might want to forward your alternative suggestion over there, but personally I think it would depart with a very commonly applied WP policy: usually the title picks just one name rather than inventing a hybrid, and then the lead lists all the main alternate names, and the alternate (but not hybrid) titled pages are made to automatically redirect to the article, therefore anyone who searches by any of the common alternates will still find it and no original jargon needs be invented.

The timeline entry for Thursday, 31 March states: "Plans begin to implement Chernobyl's concrete sarcophagus solution to Fukushima plant." The citation is inadequate but leads/links to an article in the Augusta Chronicle where Jerry Ashmore of Ashmore Concrete Contractors is quoted: "Our understanding is, they are preparing to go to next phase and it will require a lot of concrete." The use of very large concrete pumps from the same manufacturer (Putzmeister) back in 1986 at Chernobyl is mentioned, but nowhere in this article is any mention of a sarcophagus solution being planned by TEPCO. The article does seem confusing and immediately mentioning Chernobyl is somewhat sensationalistic. Neither TEPCO nor the Japanese regulators JAIF have made any announcements or statements suggesting they plan to implement a sarcophagus solution. TEPCO has been focused on restoring plant electrical systems for the last two weeks. Per the IAEA accident timeline on IAEA's site, power to the control room indicators and control equipment for units 3 and 4 (combined control room) was restored on or about April 6th. The lighting circuits had been repaired earlier for both this and the other control room serving units 1 and 2. Point being, TEPCO is doing a lot of electrical work so they can restore closed-loop cooling. That's not anything like Chernobyl, which was entombed while still hot. And why would they be trying to restore normal plant functions in a facility they intend to entomb? I can see large amounts of concrete being used as extra biological sheilding, but nothing like a complete sacrophagus. See IAEA and TEPCO websites. Secondary source: Atomic Power Review [1] A lot of data, especially data about any improvements in plant condition, has not been covered by media in the US. TEPCO is using diesel and electric pumps with backup diesel generators for most of the cooling work. TEPCO is not "struggling" to keep the reactors wet, but they are working very hard to start closed-loop cooling which will greatly improve radiation control.

This article is basically an overblown daily diary and is not encyclopedic. It is far too long and has become a dumping ground for any little snippet of information that seems to be associated with the topic. The long and sprawling tables are confusing to readers and reduce readability and neatness. Use of dot points interrupts the flow of the text and makes it difficult to read. Johnfos ( talk) 18:24, 11 April 2011 (UTC)
Yes, we can anticipate that some detail will be consolidated or perhaps removed in the ultimate editing process, but not now. The criteria for overly aggressive conventional editing have not yet evolved.
IMO, the question for editors at this stage of the article becomes: Is a new detail likely to be helpful or unhelpful to those who might consult this article during the course of an unfolding narrative? --

Material consolidated, using summary from Fukushima I nuclear accidents. Johnfos ( talk) 21:19, 11 April 2011 (UTC)
Reverting overblown copy-edit which was too bold
I would support undoing Johnfos's copy-edit. I understand the intention, but his comments in this thread were not sufficient warning. The cuts were too bold, too dramatic, too extensive.
For example, in the text for just one day -- April 6 -- everything was removed without explanation. In this one instance, the deletion of all text with inline citation support was unjustified. This kind of extensive copy-edit is arguably premature. This edit also removed many inline citations. Johnfos's judgment retains some hyperlinks which are likely to become broken within the coming months, and his decision-making deleted some inline citations (with embedded hyperlinks) which are likely to remain active.
In summary, this was simply too much. There were no redlinks in the citation notes before Johnfos's massive edit, and now they are a problem for someone else to resolve. -- Tenmei ( talk) 01:06, 12 April 2011 (UTC)
It was exactly for that reason that I opposed the split a few weeks ago. However significant the event, there is just too much "news" here and not enough encyclopaedic content. Time to get the garden shears out, peeps! -- Ohconfucius ¡digame! 10:17, 12 April 2011 (UTC)
Johnfos added headnotes which are arguably on-point. and undisputed. For example, who doesn't agree that yes, this article is too long to read and navigate comfortably. Who doesn't recognize that yes, this article does require cleanup to meet Wikipedia's quality standards.
No one misunderstood or disagreed with the reasonable goals which were very plain in
Johnfos major edit.
The question now becomes "What next?" For example, one of the headnotes poses a timely suggestion, "Please consider splitting content into sub-articles and using this article for a summary of the key points of the subject." A good starting point may be the overview and analysis summaries which Johnfos drafted. Each of the collapsed sections represent Johnfos' attempts to distill what is significant during each week of the first month. Now what? We are still in the midst of the "accident sequence". What next?
IMO, it bears repeating that experts recognize that Fukushima is not the worst nuclear accident ever but it is the most complicated. -- Tenmei ( talk) 17:33, 12 April 2011 (UTC)
The BOLD copy-edit of Johnfos is now restored in that part of the article which addresses the "accident sequence" or "event tree" in the month of March only. This proposed text can now be examined and revised in the normal course of collaborative editing.
The full log which Johnfos characterizes here as "not encyclopedic" and as "overblown daily diary which is a dumping ground for all sorts of miscellaneous news" is retained in a linked sub-article -- see Fukushima nuclear accident log, March 2011. These paragraphs and tables are also ripe for further editing and "clean-up".
In due course, some details which are now in the sub-article are likely to be restored to the main article.
Although there was general agreement that the extent of Johnfos' BOLD edit may have "pruned" too much detail, it appears that the summaries that he did prepare were given scant attention.
IMO, Johnfos' draft text does provide a valid and sufficient basis for meaningful discussion and consensus building.
In early May, I would propose to do much the same thing with that part of the article which deals with the unfolding sequence of events in April -- see Fukushima nuclear accident log, April 2011.
This means retaining the BOLD summary text that Johnfos drafted and re-locating the more detailed daily logs to a newly-created sub-article.
Is this a reasonable short-term plan? What do you think? -- Tenmei ( talk) 19:09, 13 April 2011 (UTC)
I have restored the missing information for march and frankly do not understand what is going on. The result of the deletion debate was quite clear that all the information should be kept. Not summarised. This is important information and many people want it to remain on display. It can not be removed from here unless someone comes up with a better idea of how to display it.

I find it astounding to see the note that this page is being considered for deletion.
This page is an invaluable resource to view the unfolding events.
By all means tell the story as a proper history after the event, whenever that might be, but please do not in the interim delete this page. —Preceding unsigned comment added by 62.189.77.110 ( talk) 13:29, 13 April 2011 (UTC)
I agree. This page has had better information than any other source. Don't delete it! 131.107.0.81 ( talk) 19:56, 13 April 2011 (UTC)Ksnow
Please do not delete this page, at least untill after the situation at Fukushima is resolved and then the information here can be restructured properly into articles, but as it stands it is vital source for incidents, events and reliable sources in a rapidly changing major world event 94.168.210.8 ( talk) 22:04, 13 April 2011 (UTC)
The article says "A steam-driven turbine located in Unit 3 provide cooling to Units 1, 2 and 3.[4] Later, reports indicate that only the generator for Unit 6 remained working in full operational capacity." 11 march 15:01. This is junk. it has a reference but it is wrong. Each reactor is separate so it is impossible for equipment in 3 to affect 1 and 2. The steam driven turbines use steam from that reactor to pump water through that reactor. Check the tepco reports and they say which units still had what cooling systems still operating. The generators for unit 6 were also knocked out by the tysunami. Again, the tepco reports say when they were repaired. which was quite a while later although first one and then the second generator of that pair were the first power restored on the plant.

Incidentally, I have seen suggestion that hydrogen might simply have leaked from the reactor because of the very high pressures inside which were well above working levels and therefore exceeded levels at which a leak might be expected. So although the official line is that hydrogen was vented which unfortunately caught fire, it may be that it escaped by itself. I also read that hydrogen being light might have built up in the roof space wherever it originated to dangerous levels. Sandpiper ( talk) 22:30, 13 April 2011 (UTC)
