Thank you so much I know this article is dense but I think it is a very important topic. I got all the easy points you made. I am unfortunately very busy in my personal life right now but I will get to everything in the next couple days. Czarking0 (talk) 17:35, 16 October 2024 (UTC)[reply]
2b. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose).
I'm going to place this on hold since there is several unsourced sections of text and the citations need to be edited to be consistent (either use templates or don't, either use rp or sfn) and I have a feeling that may take awhile. IntentionallyDense (talk) 04:35, 14 October 2024 (UTC)[reply]
Yes, although I didn't do that I would be opposed to changing it. If see read the 20 or so pages of talk page archives ( which I don't expect you to but I did). You will see that much of the disagreement between editors revolves around exactly what was said in the lead. Adding sources helped resolve this debate.

I also would like your opinion on this photo since it seems like in its present form it was just made by one of the editors. Not sure what to do with that. Comparison of radiation levels for different nuclear eventsCzarking0 (talk) 22:57, 17 October 2024 (UTC)[reply]
If the photo you're referring to is the "Fukushima Nuclear Accident - Radiation Comparison" (at right), I am the author, and that map is clearly marked at CC0, Public Domain. It doesn't get any more free than that. Under CC0 you technically aren't even required to cite the source, although I would appreciate it anyway. This map was also featured as a 2-page spread in the journal Elements, and also in the journal Leonardo (Vol 45, No 2, pp 113-118, Apr 2012).
Just realized you're referring to a different image regarding copyright.
In any case, this map is CC0, and the Leonardo details could work if you need a direct citation for the map itself. (Article: Visual Communication in Times of Crisis. See https://ramakarl.com/fukushima/ for citation details).
hmm in the case of the second photo I'm not quite sure what to do with that. Since it contains a lot of detail I think it would be okay to include if it is properly sourced (aka the information it uses should be sourced on the wiki page). If not then I know there is technically an inline tag for unsourced images with info like that so I would say it is a bit of a prblem if there is no sources for it. In the case of the first photo, non-free content is allowed as long as there is proper rational behind it (which I believe there is but I'm not too experienced with copyright stuff).

Done Ok that was not a very good source for that claim because the original source is describing US regulation which generally speaking Japan followed but I still replaced it with a source for the actual incident. Czarking0 (talk) 06:11, 17 October 2024 (UTC)[reply]
Upon detecting the earthquake, all three operating reactors (units 1, 2, and 3) automatically shut down. Due to expected grid failure and damage to the switch station as a result of the earthquake, the power station automatically started up the EDGs, isolated the reactor from the primary coolant loops, and activated the emergency shutdown cooling systems. is unreferenced. IntentionallyDense (talk) 01:55, 14 October 2024 (UTC)[reply]
One air cooled EDG, that of unit 6, was unaffected by the flooding and continued to operate. The DC batteries for units 1, 2, and 4 were also inoperable shortly after flooding. is unreferenced. IntentionallyDense (talk) 01:55, 14 October 2024 (UTC)[reply]
The Fukushima Nuclear Accident Independent Investigation Commission (NAIIC) was the first independent investigation commission by the National Diet in the 66-year history of Japan's constitutional government. is unreferenced. IntentionallyDense (talk) 01:55, 14 October 2024 (UTC)[reply]
The Commission recognized that the affected residents were still struggling and facing grave concerns, including the "health effects of radiation exposure, displacement, the dissolution of families, disruption of their lives and lifestyles and the contamination of vast areas of the environment". is unreferenced.

No adverse health effects among non-worker Fukushima residents have been documented that are directly attributable to radiation exposure from the accident, according to the United Nations Scientific Committee on the Effects of Atomic Radiation. is very close to the source according to [1] I'd either reword this or put it in quotes. IntentionallyDense (talk) 01:55, 14 October 2024 (UTC)[reply]
The formatting for citations isn't consistent here. At times you use plaintext citations and othertimes you use templates. Sometimes you use RP and other times SFNs. IntentionallyDense (talk) 04:22, 14 October 2024 (UTC)[reply]
It actually is apart of the GA criteria. I might need to get a second opinion here but according to Wikipedia:What the Good article criteria are not “Any system that allows the reader to connect a specific sentence with a specific citation is an acceptable inline citation method. However, one system should be used consistently for inline citations.” IntentionallyDense (talk) 17:38, 16 October 2024 (UTC)[reply]
I'm going to start to assess some of the other areas while this is on hold. All acronyms (such as INES and NISA) should be spealt out in full the first time they are used. IntentionallyDense (talk) 22:01, 15 October 2024 (UTC)[reply]
I feel like you could cut back some of the detail and move it to the corresponding articles in the sections Unit 1, Unit 2, Unit 3, International impact, Radiation effects in humans, and Treating contaminated water. Some of these sections may have less material to remove than others but every little bit counts. IntentionallyDense (talk) 22:01, 15 October 2024 (UTC)[reply]
I agree this article is a bit long. I think the talk pages debated this particular point in detail. I will have to reread them to see if there was some consensus there. Czarking0 (talk) 17:29, 16 October 2024 (UTC)[reply]
Getting to all your points in due; however, I wanted to point out that citation format sfv vs rp, etc is not a GA criteria. It is for FA Czarking0 (talk) 15:55, 16 October 2024 (UTC)[reply]
It is because Criterion 1 requires compliance with MOS:LAYOUT, and criterion 2 also requires compliance with the MOS:LAYOUT section MOS:REFERENCES. It says:
"No adverse health effects among Fukushima residents have been documented that are directly attributable to radiation exposure from the Fukushima Daiichi nuclear plant accident" - United Nations Scientific Committee on the Effects of Atomic Radiation. Seems out of place. Consider maybe wording it as "according to" or something similar. IntentionallyDense (talk) 03:30, 22 October 2024 (UTC)[reply]
Zircaloy can be oxidized by steam to form hydrogen gas or by uranium dioxide to form uranium metal. I'm a little unsure about what you mean here. do high temperatures also create uranium metal or is that the uranium dioxide. If it is the former is that relevant to the article? IntentionallyDense (talk) 03:30, 22 October 2024 (UTC)[reply]
My understanding is that both these reactions would be contributing to the meltdown. The high temp, high pressure steam from emergency cooling systems should oxidize the components. This is bad because it weakens the material. The source calls out the exothermic nature of this but how important that heat is compared to the reactor itself would require expert analysis. FN29 seems to indicate it is not negligible.
The second reaction very important. This is the primary reaction that causes the meltdown/ melt-through. As the uranium oxidizes the vessel it will melt/ break the zircaloy and eventually escape. This is part of how the fuel ends up outside of the containment.
Now the source for this section is not actually about Fukushima at all and it just background info on reactor chemistry so I am not sure how to edit the article. Maybe the summary sentence is "these reactions are important processes in how a zircaloy cladding fails during meltdown."
To me this just boarders on super technical information that WP is not super well suited for. I would also consider deleting this materials section and seeing where else in the article this info might be relevant. Czarking0 (talk) 16:56, 23 October 2024 (UTC)[reply]
DC power was needed to remotely control it and receive parameters and indications and AC power was required to power the isolation valves. Acronyms should be spelt out in full when first used. IntentionallyDense (talk) 03:30, 22 October 2024 (UTC)[reply]
Is there a guidance on this? All times are local to the accident and I think it makes sense to present it that way. This is actually stated at the top of the article in a hidden note. Czarking0 (talk) 15:44, 23 October 2024 (UTC)[reply]
You switch between giving times and saying 50 minutes after etc. I think for clarity purposes it would be easier to stick to either giving times or minutes after. IntentionallyDense (talk) 22:39, 22 October 2024 (UTC)[reply]
I reviewed these and I think it sounds good the way it is. Willing to discuss specific examples. Like this with sentence "The largest tsunami wave was 13–14 m (43–46 feet) high and hit approximately 50 minutes after the initial earthquake" the relative time is providing context between the beginning of the two important but distinct historical events of the tsunami and the nuclear accident. I think it is important to keep it relative here Czarking0 (talk) 00:46, 27 October 2024 (UTC)[reply]
The DC batteries for units 1, 2, and 4 were also inoperable shortly after flooding Why? I'm assuming it was due to the flooding but I think clarification would be nice here. IntentionallyDense (talk) 22:39, 22 October 2024 (UTC)[reply]
In response, the operators assumed a loss of coolant in units 1 and 2, developing a plan in which they would vent the primary containment and inject water into the reactor vessels with firefighting equipment. might sound better as In response, the operators assumed a loss of coolant in units 1 and 2 and developed a plan in which they would vent the primary containment and inject water into the reactor vessels with firefighting equipment.IntentionallyDense (talk) 22:39, 22 October 2024 (UTC)[reply]
09:15 leading directly from the water storage tank to the injection port to allow for continuous operation (the fire engine had to be periodically refilled). timezone. IntentionallyDense (talk) 22:39, 22 October 2024 (UTC)[reply]
Since we are trying to make this shorter anyway I edited this out. FYI the explosion was the hydrogen which is created by the reactor and water. Czarking0 (talk) 00:35, 27 October 2024 (UTC)[reply]
"the melted fuel in Unit 1, whose core damage was the most extensive, has breached the bottom of the primary containment vessel and even partially eaten into its concrete foundation, coming within about 30 cm (1 ft) of leaking into the ground" I believe quotes need to be cited right after they are given.

In the initial hours of the accident, in response to station blackout and uncertainty regarding the cooling status of units 1 and 2, a 2 km radius evacuation of 1,900 residents was ordered at 20:50. The phrasing here is a bit hard to follow, could you reword? IntentionallyDense (talk) 02:50, 23 October 2024 (UTC)[reply]
The size of these evacuation zones was set for arbitrary reasons at the discretion of bureaucrats rather than nuclear experts. This doesn't sound very NPOV. Maybe consider rewording to "nuclear experts criticize that..." or something. IntentionallyDense (talk) 02:50, 23 October 2024 (UTC)[reply]
The source here is the investigation by the national diet of japan so I think this is a neutral POV. The claim here is simply a matter of fact. The group making these decisions were not nuclear experts and were career bureaucrats. Czarking0 (talk) 00:50, 27 October 2024 (UTC)[reply]
In the aftermath, Germany accelerated plans to close its nuclear power reactors and decided to phase out the rest by 2022[107] (see also Nuclear power in Germany). the see also part looks a bit awkward. maybe wikilink Germany with the relevant link instead.

Well to me this is the updated info. I worked on this section before the GAN. As you can see the sources are from 2023 so it is fairly recent. I could search for 2024 sources but I think this section clearly shows that the cleanup timeline is quite long so I don't expect meaningful change year over year.

As of October 2019, the total amount of tritium in the water was about 856 terabecquerels, and the average tritium concentration was about 0.73 megabecquerels per liter. Is there any relevant info on wether or not tritium has any health or environmental effects? IntentionallyDense (talk) 03:09, 23 October 2024 (UTC)[reply]
Working on this. I don't think there is a clear yes/no answer. This appears to be the authoritative source on the subject; however, I do not speak french. I will use some Japanese sources that reference this. Czarking0 (talk) 15:53, 27 October 2024 (UTC)[reply]
Yeah I think it is fine to leave as is. I'm Canadian so I'm used to there either being USD or CAD behind prices but that may have been my personal experiences getting in the way. IntentionallyDense (talk) 19:07, 23 October 2024 (UTC)[reply]
They take advantage of convection (hot water tends to rise) and gravity (water tends to fall) to ensure an adequate supply of cooling water to handle the decay heat, without the use of pumps. I don't think the explanations of convection and gravity are needed but let me know what you think. IntentionallyDense (talk) 03:09, 23 October 2024 (UTC)[reply]
Czarking0 I have finished my review. Overall, great work. I can't imagine taking on such a big topic. I wrote a lot of feedback as there was a lot of content but I don't want that to scare you in any way. If you disagree with some of my suggestions just let me know and I'm sure we can find a way to work it out. If this article passes (which I really hope it does!) I hope you will consider nominating it for DYK as it would make a great topic for that kind of thing. IntentionallyDense (talk) 03:14, 23 October 2024 (UTC)[reply]
