Comment: The article might have been nominated earlier, but the US National Parks Service website suddenly went down in January. It's back now.

What was the appeal of Oak Ridge? Cheap TVA power?
He reasoned that it would primarily be a research and educational facility, and that expertise was to be found at the Metallurgical Laboratory. Compton was shocked.[22] The Metallurgical Laboratory was part of the University of Chicago, so the university would be operating an industrial facility 500 miles (800 km) from its main campus. Can you fold the bit about Compton being shocked into one of the other sentences?
Cast uranium billets came from Metal Hydrides, Mallinckrodt and other suppliers. These were extruded into cylindrical slugs, and canned by Alcoa, which started production on June 14, 1943.[37] The fuel slugs were canned primarily to protect the uranium metal from corrosion that would occur if it came into contact with water, but also to prevent the venting of gaseous radioactive fission products that might be formed when they were irradiated. The cladding had to transmit heat but not absorb too many neutrons. Aluminum was chosen. reword this
The order of these sentences isn't logical and reads awkwardly. Tell the reader much earlier that aluminum was chosen because of X & Y and then get into who and when. Except in dialog, three-word sentences are best avoided as they can usually be integrated into the sentences around them where things will flow better.--

Okay. The text now reads The fuel slugs were canned to protect the uranium metal from corrosion that would occur if it came into contact with water, and to prevent the venting of gaseous radioactive fission products that might be formed when they were irradiated. Aluminum was chosen as it transmitted heat but did not absorb too many neutrons. Alcoa started canning on June 14, 1943. General Electric and the Metallurgical Laboratory developed a new welding technique to seal the cans airtight, and the equipment for this was installed in the production line at Alcoa in October 1943.Hawkeye7 (

Unfortunately, operations did not detect the effect of the neutron poison Operations?
During 2015 tours were part of a general three-hour tour of the Clinton Engineer Works facilities, and were conducted on Mondays through Fridays at noon, from June 4 to September 30, except on July 4 and 5. Not really relevant. Best if handled in an external link to the Museum.
Support and source review I reviewed this article closely at GAN and Milhist A-Class and have reviewed all subsequent edits, including those made during this review. I believe it meets the FA criteria. I have also checked the sources, and believe they are of a high standard and are consistently formatted. I have spotchecked several of the citations and they check out.

SupportComments -- I'll comment as I read:
"At the time only such minute quantities of plutonium-239 had been produced, in cyclotrons, and it was not possible to produce a sufficiently large quantity that way." maybe "At the time plutonium-239 had only been produced using cyclotrons, and it was not possible to produce exploitable quantities that way." or something
"Compton and the staff at the Metallurgical Laboratory then reopened the question of building the plutonium semiworks at Argonne. But the engineers and management of DuPont disagreed" -- did they disagree with reopening a question?
" especially to the research staff from the Metallurgical Laboratory, whom they feared would attempt to interfere unduly." -- they felt the research staff would interfere, or they felt they would be interfered with?
I think that heavy water and graphite are
neutron moderators is mentioned too late. This should be introduced then discussed (briefly), at the moment it's split in a strange way over the first paragraph of "Design"
I'm assuming the helium coolant is the gas rather than liquid? It should probably be explcitly stated. If the liquid adding it's boiling point would make it clear to even lay people that a liquid-helium cooled system would pose a greater engineering challenge than a water cooled system.
"This reactor only generated up to 200 W, but it demonstrated that k was higher than anticipated." -- mention that Chicago Pile-1 used graphite as a moderator.
The article
Bismuth phosphate process does nothing to help me understand what at all is involved in the separation process. Is a one or two sentence note possible that discusses this?
This is only a suggestion, but a one sentence explanation of the function of a control rod would be valuable.
This is what I thought. In that case I think the information on the actual separation process itself needs some expansion in the article. Not much (two sentences?) but at the moment it's a black box, and the
Bismuth phosphate process article (as I mentioned above) doesn't provide much information. --

I read the lead last and am happy with it. I have not checked the infoboxes or captions. Overall an impressive and interesting article. Most of my comments are relatively minor and hopefully shouldn't be hard to address. Thanks for the fascinating read. --

"Closing comment': There is one instance of refs not being in numerical order, which I tweaked, but if it was deliberate, feel free to revert.
