NERVA

 * Nominator(s): Hawkeye7   (discuss)  03:40, 26 March 2022 (UTC)

This article is about NERVA, the NASA nuclear rocket project. Unlike its forerunner, Project Rover, it developed entire engines and not just reactors for them. Hawkeye7  (discuss)  03:40, 26 March 2022 (UTC)
 * Image review—pass no licensing issues found (t &#183; c)  buidhe  03:46, 26 March 2022 (UTC)
 * do you feel that your opposition at the last FAC still applies, or have the redundancy issues been resolved? (t &#183; c)  buidhe  04:41, 26 March 2022 (UTC)
 * I don't have the time to do an exhaustive analysis, but at first glance, I don't believe they have. These are the combined diffs since the previous FAC at NERVA and Project Rover, and one can see that no restructuring has occurred, nor has substantial unique content been added. Very large portions of the two articles are thus functionally identical. Vanamonde (Talk) 15:50, 26 March 2022 (UTC)
 * As a very rough indicator of redundancy, take a look at this result from Earwig's tool . To be clear, I am not saying there's copyvio here, I'm just trying to estimate shared content. Also, this is a serious underestimate, because Earwig only flags text matches, not content matches. Vanamonde (Talk) 17:40, 28 March 2022 (UTC)
 * Your point is accepted. This is an artefact of the way that an encyclopaedia organizes articles around subjects. The separation of Rover from NERVA was there before expansion began, and there was no support for merging. They diverge after the material on Project Rover. While DYK has rules about shared content, there are none at FAC, and my contention is that the NERVA article is complete. Hawkeye7   (discuss)  20:14, 30 March 2022 (UTC)
 * Support, comprehensive and accurate. There's not much else that I can say. CactiStaccingCrane (talk) 03:18, 28 March 2022 (UTC)
 * Support An amazing article. I have added some explanatory text on rocket basics so readers don't have to click out to understand the basic concepts. I also mentioned ARPA, because I think it's useful to understand how the existing programs were split up. Other than that, I found it fascinating and complete. I was especially surprised by the budgets and manpower applied, as I had always thought of it as a relatively small program, but with 1,100 people at a single contractor we are certainly in the area of big science! I'm not sure about the use of "reckoned" as that might not translate properly, but that's no reason to hold up an FA. Good to go here. Maury Markowitz (talk) 17:25, 30 March 2022 (UTC)

Comments by Wehwalt

 * "which may be more efficient than chemical engines" maybe "could" or "might" for "may", since we're dealing with the past?
 * Reworded. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * " They reluctantly concluded that nuclear rockets were essential for deep space exploration, but not yet technically feasible.[5][6]" Since their reluctant conclusion is quite late in the sentence, I'd put a "while" after "that".
 * Added. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * " This combination of features allows a nuclear engine to outperform a chemical one, they generally aim to have at least twice the specific impulse of a chemical engine.[18]" perhaps the comma should be a semicolon as both parts of the sentence would pass as sentences on their own.
 * Replaced comma with semicolon. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * You shorten Los Alamos Scientific Laboratory both as LASL and as Los Alamos. I might pick one or the other and use it consistently.
 * Settled on LASL. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * Lewis is double-linked.
 * Removed duplicate links. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * "Then, on 12 April, the Soviet Union launched Yuri Gagarin into orbit on Vostok 1, once again demonstrating their technological superiority." Possibly "their" should be "its" in AmEng.
 * Changed as suggested. Hawkeye7   (discuss)  19:40, 4 April 2022 (UTC)
 * " Test Cell C was supposed to be complete in 1960, but NASA and AEC did not request funds for additional construction in 1960, although Senator Anderson provided them anyway." Two things. "But" and "although" in succession makes a sentence feel like a tennis match, and can we lose one use of "in 1960"?
 * Re-worded. Hawkeye7   (discuss)  19:42, 4 April 2022 (UTC)
 * More soon.--Wehwalt (talk) 17:45, 4 April 2022 (UTC)
 * "The subsequent full-power Kiwi B4A test on 30 November 1962, along with a series of cold flow tests revealed that the problem was vibrations induced as the hydrogen was heated when the reactor was brought to full power that shook the reactor apart (rather than when it was running at full power).[73] " This sentence could benefit from commas or reorganization.
 * Added a comma, and tweaked the wording. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * "Components that would not affect system performance were allowed to be selected from what was available at Jackass Flats" I might cut "allowed to be".
 * Deleted. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * " Congress cut the NASA's budget to $3.8 billion." Extraneous "the".
 * Deleted. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * "NASA program funding was somewhat reduced by Congress for the 1969 budget, shutting down the Saturn V production line and cancelling Apollo missions after Apollo 17," My understanding was that Apollo 20 was canceled around New Year's 1970 and the two other canceled missions in September 1970.
 * Apollo 20 was canceled in May 1969 to allow for Skylab; Apollo 15 and 19 were cancelled in September 1970. Added this. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * Our article says that Apollo 20's cancellation was announced 4 January 1970.--Wehwalt (talk) 20:55, 6 April 2022 (UTC)
 * Hmm. That seems to be when it was announced. Changed the text accordingly. Hawkeye7   (discuss)  21:38, 6 April 2022 (UTC)
 * " mostly in California, a state that Nixon needed to carry in the 1972 election.[107]" He didn't as it proved. Perhaps "felt he needed to carry"?
 * Changed as suggested. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * "Pewee" You mention this for the first time at the end of the article and relate it to Project Rover.
 * Deleted. Hawkeye7   (discuss)  20:14, 5 April 2022 (UTC)
 * That's it.--Wehwalt (talk) 16:42, 5 April 2022 (UTC)

Source review – Pass
Will do soon. Aza24 (talk) 20:44, 14 April 2022 (UTC)


 * Formatting
 * Publisher for Chovit, A. R.; Plebuch, R. K?
 * Dewar, James doesn't have the state like the other refs
 * Robbins and Finger has "NASA Lewis Research Center, NASA"—is it needed both times?
 * You don't give the state for Burlington in Dewar like the others
 * retrieval dates missing for 16, 17 and 18
 * ref 6 should be either The Telegraph or The Daily Telegraph
 * Date missing for ref 104
 * All of these have been added/corrected. Hawkeye7   (discuss)  09:24, 18 April 2022 (UTC)


 * Reliability
 * What makes ref 122 a high quality and reliable source?
 * Space Media Network is a commercial news service. It has its own staff writers and also takes feed from wire services. The article in question was written by the NASA Narshall Space Flight Center.
 * Seems valid to me. Aza24 (talk) 07:40, 19 April 2022 (UTC)

Thanks for the review. Much appreciated. Hawkeye7  (discuss)  09:24, 18 April 2022 (UTC)
 * Verifiability
 * Spotchecked a few pdf pages and found no issues Aza24 (talk) 06:58, 18 April 2022 (UTC)
 * Happy to help. Pass for source review. Aza24 (talk) 07:40, 19 April 2022 (UTC)

Support from Gog the Mild
Recusing to review. More to follow. Gog the Mild (talk) 21:06, 11 May 2022 (UTC)
 * "classified as Restricted Data". Why the upper case initial letters?
 * It is capitalised in our article, Department of Energy documents, and the US Atomic Energy Act. So that is the legal form in the United States. Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "For the fuel, plutonium-239, uranium-235 and uranium-233 have been considered." Should that not be '... were considered'?
 * Yes. Re-worded. Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "and in any case it was not readily available". Does this mean that uranium-235 was selected? If so, perhaps mention that?
 * Good idea. Mentioned. Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "Later thirty trailers were brought to Jackass Flats to create a village". For many readers the link between trailers and living accommodation will be opaque. Is there not a link? Or perhaps a bracketed translation?
 * That's what they called them in Texas. Our article is called mobile home so switched to that. (In Texas there was a superstition that they attracted hurricanes.) Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "to work liaise with LASL". Is "to work liaise" a typo?
 * Deleted "work". Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "so that the decision to proceed". Was that the reality, or should it read 'so that the decision whether to proceed'?
 * Sure. Changed as suggested. Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)
 * "NASA estimated its cost at $800 million". The cost of what? The total anticipated cost of NERVA, the spend to date or the cost of cancellation? (Or something else?)
 * Added "ultimately" to make this clearer. Hawkeye7   (discuss)  22:13, 11 May 2022 (UTC)

That's all I have. Another classic. I note obiter dicta that I am content that NERVA is a free-standing article. Gog the Mild (talk) 21:29, 13 May 2022 (UTC)
 * "which could be performed by Saturn V". Is this meant to imply that RIFT and/or RIFT/NERVA couldn't?
 * It most certainly could have. Reworded to make this clearer. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * "The RIFT vehicle would consist of". Should 'test' be inserted after RIFT?
 * Sure. Added.  Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * Link dirigible.
 * Linked. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * "In August 1961, the Soviet Union ended the nuclear test moratorium that had been in place since November 1958, so Kennedy resumed US testing in September." → '... so Kennedy resumed US testing of nuclear weapons in September' would make this clearer.
 * Changed as suggested. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * "which could leak through microscopic holes that would contain other fluids." This reads as if it were the holes that would contain other fluids.
 * Re-worded. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * "The sensors recorded that they had reached 1,095 K (822 °C), which was their own maximum." Do you mean 'The sensors recorded that they had reached at least 1,095 K (822 °C), which was their own maximum'? (Or 'The sensors recorded 1,095 K (822 °C), which was their own maximum'?)
 * The sensors. Reworded. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)
 * "which would allow the upgraded Saturn to launch much larger payloads". Much larger than what?
 * Reworded. Hawkeye7   (discuss)  04:46, 14 May 2022 (UTC)

For people who don't think you need the toolset or technical knowledge to work on content, for this article I had to edit Infobox rocket engine and Infobox nuclear reactor so the former could embed the latter. Hawkeye7  (discuss)  22:13, 11 May 2022 (UTC)
