== Semi-protected edit request on 11 August 2024 ==
== Coolant Flow paradox needs further discussion. ==


{{edit semi-protected|Chernobyl disaster|answered=yes}}
In the last paragraph of "Background", just before we enter the "Accident", the following statement is made: "'''excessively high coolant flow rates through the core meant that the coolant was entering the reactor very close to the boiling point.'''" Boiling coolant leads to steam bubbles which creates a non-liquid neutron absorbing void in the reactor core. This is clear in the discussion. However, the statement referenced appears to say that high coolant flow leads to high coolant temperatures - which is counterintuitive. In theory, if you want to cool something down, you increase the coolant flow. Perhaps there is a link to high coolant flow necessitating high coolant flow through the heat exchange system, and hence quickly moving coolant does not get a chance to cool before it reenters the reactor. (Note "perhaps", it's been a long time since I took a reactor design course.) "Bottom line", as Michael Weston would say, is this critical state of high coolant flow leading to boiling point coolant needs to be explained for it in some ways is the cause of the entire accident.

== Getting this to a Good Article state ==
== Grammar edit recommendation ==


After few years, I have come back to the article and made a variety of significant edits, mainly simplifying the overall layout. My goal would be to get this article to a state where it can be nominated to a Good Article and a Featured Article - seems worthwhile given the importance of the event as well as this article being in the Top 100 visited articles.
In the first paragraph of (Top), The following fact is told:
"The initial emergency response and subsequent mitigation efforts involved more than 500,000 personnel and cost an estimated 18 billion roubles"


I'm not sure how much time I can invest into this of course, but seeing a variety of activity from others recently inspired me and I thought I'd start a collaborative checklist below. Feel free to edit it further, or cross out things that are done!
The problem is, I am 70% sure that "and cost an estimated 10 billion roubles" is not correct. Noting the article is written in past tense, I'm pretty sure "cost" should be "costed".

* Reconcile the Long-term effects section with the [[Effects of the Chernobyl disaster]] article. There is significant overlap but also differences, and I believe the section would benefit from trimming down details.

== Grammar ==
== NPOV issues with "Disputed investigation" section. ==


The first sentence of the sub-section "Fuel-containing materials" has a grammatical error. The first sentence reads "About 95% of the fuel in reactor No. 4 at the time of the accident." This is obviously not a complete sentence. It is unclear to me what the original literary intent of this clause was. This half-sentence could be removed without impeding the reader's understanding of the following text. [[User:CALPHone|CALPHone]] ([[User talk:CALPHone|talk]]) 19:33, 2 October 2024 (UTC)
This section comes across as if written by a pro-nuclear defender (or apologist, depending on your POV). It mentions "Moller has been reprimanded for publishing papers that crossed the scientific "misconduct"/"fraud" line." but reading the citation/source doesn't support the wording in the article. Moller was indeed accused of scientific misconduct"/"fraud but a French panel of scientists found no credible evidence to support the claim, so it seems that claim is disputed (according to the Nature article used a source). There is talk about "continuing to publish experimentally unrepeatable and discredited papers." but no source shows that there is a a consensus that Mousseau appears related to the Chernobyl disaster general considered discredited or that his reputation overall is such that all his work should be discounted outright. Once citation/source links to a guest column at AtomicInsights.com that is the opinion by only one individual who disputes a talk Mousseau gave on Fukushima (not The Chernobyl disaster). This seems sort like an add-hominem attach on the guy because of disagreement over his Fukushima talk. If his is generally discredited in the scientific community then multiple better sources should be able to be produced and cited. Finally, the section claims the book "Chernobyl: Consequences of the Catastrophe for People and the Environment" been generally discredited but neither the link presented support that claim not does the Wikipedia article on the book. It's fair to say the book is "disputed" but we need better sources if you want to claim has been "discredited". This article is not the place to debate or address the anti-nuclear movement in general as there are other Wikipedia article for that. Stick to addressing specific claims about the effects of medical & environmental of the Chernobyl Disaster specifically and whether it supports any anti-nuclear arguments or not. Leave the general arguments pro and con about nuclear energy in general to the article on Nuclear Energy, Anti-Nuclear movement, Nuclear Energy Safety, etc. - [[User:Notcharliechaplin|Notcharliechaplin]] ([[User talk:Notcharliechaplin|talk]]) 22:50, 12 June 2024 (UTC)

{{edit semi-protected|Chernobyl disaster|answered=yes}}
In the section '''Immediate site and area remediation''', specifically in the sub-section '''Area cleanup''', the following is stated:
Under the "In popular culture" section, it says THQ produced STALKER, this is not true GSC Gameworld, a Ukrainian video games developer, produced it. [[User:Wikipedianikolas|Wikipedianikolas]] ([[User talk:Wikipedianikolas|talk]]) 16:31, 12 November 2024 (UTC)

:{{done}}<!-- Template:ESp --> The article doesn't say THQ produced the game, it says it released it, which according to the game's article would appear to be true. With that said, I'm of the opinion that a video game's developer is usually far more responsible for it than its publisher, so I added a few words that include GSC's role.

''Although a number of radioactive emergency vehicles were buried in trenches, many of the vehicles used by the liquidators, including the helicopters, <u>still remained, as of 2018</u>, parked in a field in the Chernobyl area.''

This statement is not correct, as comparison photos [https://imgur.com/a/graveyard-Ous53 here] show the field being completely emptied some time between April 2012 and July 2013.

I suggest the following re-wording of the above text:

''Although a number of radioactive emergency vehicles were buried in trenches, many of the vehicles used by the liquidators, including the helicopters, remained parked in a field in the Chernobyl area, some for over 20 years. Satellite imagery shows that the vehicles were progressively removed in the early 2000's with the field being completely emptied by July 2013.''

Current status: Former featured article candidate


Grammar

[edit]

The fist sentence should read: "At the Chernobyl Nuclear Power Plant in the city of Pripyat, located in the then Ukrainian Soviet Socialist Republic of the Soviet Union (USSR)" instead of: "at the Chernobyl Nuclear Power Plant in the city of Pripyat, then located in the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR)". It did not physically move.

The section titled "Social Economic Effects" should be renamed to "socioeconomic effects" to reflect proper terminology.

minor but this is the English language page "Numerous structural and construction quality issues, as well as deviations from the original plant design, had been known to KGB since at least 1973 and passed on to the Central Committee, which take no action and classified the information." should be "been known to the KGB... which took no action"

Containing fire

[edit]

The timeline says all fires were contained at 6:35 - this should probably mention "fires around the power plant": The core continued to burn days after, but there is no description what measures really lead to containing the fire inside the reactor. It just says "It is now known that virtually none of the neutron absorbers reached the core." It is not clear what really stopped the fire.

decay heat was the "fire" and it "stopped" being "red hot" like decay heat always does. With time.

Grammar edit request

[edit]

There's a rather extended high-comma-count "sentence" with what looks to be a misspelling.

The expected highest body activity was in the first few years, were the unabated ingestion of local food, primarily milk consumption, resulted in the transfer of activity from soil to body, after the dissolution of the USSR, the now reduced scale initiative to monitor the human body activity in these regions of Ukraine, recorded a small and gradual half-decadal-long rise, in internal committed dose, before returning to the previous trend of observing ever lower body counts each year.

minimal-change improvement:

The expected highest body activity was in the first few years, where the unabated ingestion of local food (primarily milk) resulted in the transfer of activity from soil to body. After the dissolution of the USSR, the now reduced scale initiative to monitor the human body activity in these regions of Ukraine recorded a small and gradual half-decadal-long rise in internal committed dose before returning to the previous trend of observing ever lower body counts each year.
