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.
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 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 game.
Uranium-235 is necessary to create uranium fuel cells and atomic bombs, 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.
It should be noted that U-238 is not useless; it is needed to manufacture uranium rounds magazines, uranium cannon shells, and explosive uranium cannon shells, 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, Used up uranium fuel cells can be reprocessed into a modest amount of U-238.)
Trivia
- The Kovarex enrichment process is named after Michal Kovařík, lead designer of Factorio and co-owner of Wube, whose online nick is kovarex (which he usually spells lowercase). [1]
- In the real world, uranium-235 is the most common fissile isotope of uranium and makes up approximately 0.72% of naturally-occurring uranium, with the other 99.28% being uranium-238. The in-game representation is thus highly accurate in this regard. Uranium is commonly enriched in centrifuges by merely separating isotopes to increase the percentage of 235U for use in fission reactions. As the Kovarex enrichment process produces more fissile material than its input, the process is more akin to plutonium breeding. Reddit discussion: Kovarex enrichment is plutonium breeding… right?
- Uranium munitions are made from depleted uranium, a byproduct of uranium enrichment, which is mostly 238U whose natural admixture of the 235U 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.
