	~~The~~ '''Kovarex enrichment process''' is a ~~method for reprocessing uranium in a~~ [[~~centrifuge~~]]~~. Although the process requires a large amount of the much rarer~~ [[uranium-235]] ~~to start, it can be~~ a ~~good way to get more use out of the available~~ [[~~uranium ore~~]].		'''Kovarex enrichment process''' is a crafting recipe to reprocess [[uranium-238]] and [[uranium-235]] in a [[centrifuge]]. It converts U-238 to U-235 at a 3:1 ratio.

	== Purpose ==		== Purpose ==
	[[Uranium processing]] ~~takes~~ 10 uranium ore ~~and returns~~ 1 ~~uranium~~-235 with 0.007 (0.7%) ~~probability,~~ or 1 ~~[[uranium~~-238]] with 0.993 (99.3%) ~~probability~~, leading to an [[:Wikipedia:Binomial_distribution\|expected]] ~~(though not guaranteed)~~ 1 ~~unit of uranium~~-235 per ~~approximately~~ 143 ~~processing~~ cycles (or about a 1:142 ratio of U-235 to U-238~~). This is currently the only probability-based crafting recipe in the base game~~.		The kovarex enrichment process is useful because [[Uranium processing\|uranium (ore) processing]] is probability-based and players cannot directly alter the probabilities. 10 uranium ore is processed into either 1 U-235 with a probability of 0.007 (0.7% chance) or 1 U-238 with a probability of 0.993 (99.3% chance), leading to an [[:Wikipedia:Binomial_distribution\|expected]] output of 1 U-235 per ~143 crafting cycles, or about a 1:142 ratio of U-235 to U-238.

	~~Uranium~~-235 is ~~necessary~~ to ~~create~~ [[uranium fuel cell]]s and [[atomic bomb]]s~~, in considerable quantities for the latter~~, but the probability distribution of uranium processing ~~leads~~ to ~~it being produced slowly~~ and ~~creating~~ large ~~stockpiles~~ of U-238 ~~as a byproduct~~. ~~The~~ Kovarex process ~~thus provides the player with a considerably~~ faster ~~(and~~ deterministic~~) method~~ of ~~producing~~ U-235~~, as well as a use for the~~ surplus U-238.		U-235 is used to produce [[uranium fuel cell]]s, [[Nuclear fuel\|nuclear fuel]], and [[atomic bomb]]s, but the probability distribution of uranium processing can lead to slow production of U-235 and a large surplus of U-238. Kovarex enrichment process enables faster, deterministic production of U-235 from surplus U-238.

	~~It should be noted~~ that U-238 is ~~not useless; it~~ is ~~needed to manufacture~~ [[uranium rounds magazine]]s, [[uranium cannon shell]]s, and [[explosive uranium cannon shell]]s~~, and~~ is ~~required as~~ a ~~secondary ingredient in uranium fuel cells. Therefore~~, ~~it is not advisable to use~~ the ~~Kovarex process to convert ''all'' stockpiled~~ U-238 ~~into~~ U-235. ~~(Although, in case of shortage,~~ [[~~depleted uranium fuel cell~~]]~~s can be [[Nuclear fuel reprocessing\|reprocessed]] into a modest amount of~~ U-238.)		Note that converting ''all'' U-238 into U-235 is inadvisable, since U-238 is an ingredient of uranium fuel cells, [[uranium rounds magazine]]s, [[uranium cannon shell]]s, and [[explosive uranium cannon shell]]s.

			== Catalyst ==
			Kovarex enrichment process is a [[Productivity#Catalysts\|catalytic recipe]], producing and consuming the same items. The net effect of each crafting cycle consumes 3 U-238 and produces 1 U-235. The remaining 40 U-235 and 2 U-238 are treated as catalysts for the net production.

			[[Productivity]] bonuses only apply to the net production, not the catalysts. When productivity generates extra output, it generates 1 U-235 and 0 U-238 — not 41 and 2.

The in-game representation is thus highly accurate in this regard. Uranium is commonly [[:Wikipedia:Enriched_uranium\|enriched]] in centrifuges by merely separating isotopes to increase the percentage of <sup>235</sup>U for use in fission reactions.

	* Uranium munitions are made from [[:Wikipedia:depleted uranium\|depleted uranium]], a byproduct of uranium enrichment, which is mostly <sup>238</sup>U whose natural admixture of the <sup>235</sup>U isotope has been lowered even further through the enrichment process. Depleted uranium is minimally radioactive and the reason for its use in munitions is its very high density and other mechanical properties, not radioactivity/toxicity.		* Uranium munitions are made from [[:Wikipedia:depleted uranium\|depleted uranium]], a byproduct of uranium enrichment, which is mostly <sup>238</sup>U whose natural admixture of the <sup>235</sup>U isotope has been lowered even further through the enrichment process.

Kovarex enrichment process - Revision history

Bilka: don't abbreviate the uraniums

Taekwonjoe2001: /* Trivia */ nick -> nickname

HeliGungir: Added catalyst section. Considerable edits to description and purpose sections. Added trivia

Bilka: Renamed from used up uranium fuel cell to depleted uranium fuel cell in 2.0
