A micro-nuclear reactor combined with complex chemical synthesis replaces the body's need for food energy. Food is required only to replace matter lost from the body, reducing the user's intake needs significantly. This artificial stomach cannot get food poisoning. However, there is little room to shield the reactor, so the radiation increases the risk of cancer.

The Nuclear Stomach drastically reduces a pawn's hunger rate to just one-quarter of its normal value and prevents food poisoning, however it causes an elevated rate of cancer. Like a bionic stomach, it also provides 125% part efficiency.
Shocking a pawn with this stomach using EMP will force them to vomit.
Nuclear stomachs can be crafted at the fabrication bench once Artificial Metabolism, which requires a techprint, is researched. They require 15 Plasteel, 4 Advanced components and a Crafting skill of 8.
A nuclear stomach reduces the hunger rate of a pawn by 75%, meaning they only require 1/4 the food to live. They also improve a pawn's metabolism by 12.5%, which improves the rest rate multiplier by 3.75%, slightly reducing the need for sleep. All artificial stomachs are immune to gut worms, and installing one will instantly cure the degrees. A nuclear stomach also grants full immunity to food poisoning. Eating capacity and eating speed are unaffected.
However, it also causes a cancer on the torso of the host pawn on average once every 120 in-game days. Without the cancer, the nuclear stomach would otherwise be a direct upgrade to, and combination of, both the sterilizing stomach and the reprocessor stomach.
If the operation fails, the part has a chanceto be destroyed.

The nuclear stomach is a cheaper way to reduce time sleeping than upgrading to a royal bed, however both can be combined.
It is worthwhile considering to install it on slaves late game, since it reduces the food cost and slaves can be replaced easily if the surgery for the cancer fails or the surgery isn't attempted. The stomach can even be removed from the slave before death to implant into their replacement once it becomes clear that the cancer will be fatal.
While EMP-wielding enemies are relatively rare, due to the induced vomiting, friendly fire is a relevant concern on melee pawns as using EMP grenades and melee attackers on Centipedes is a common and successful tactic. Having a nuclear stomach on those melee pawns will result in them vomiting and negatively affecting this tactic and others like it. However, this can also be exploited against enemies with part, as well as against escaping prisoners or rebellious slaves. For the latter two options however, use of an implant that causes brain shock may be more useful as it downs the pawn, rather than merely causes temporary vomiting.
The Royalty DLC introduced a number of stomach replacements to complement the base bionic stomach, each with their own advantages and disadvantages. All three of these variants include the benefits offered by the bionic stomach in addition to their unique benefits however they are also susceptible to EMP, causing the pawn to vomit uncontrollably for a short length of time.
In comparison to the nuclear stomach, the bionic stomach eliminates the vulnerability to EMP and cancer risk in exchange for being vulnerable to food poisoning and requiring 4x as much food.
In comparison to the nuclear stomach, the sterilizing stomach eliminates the cancer risk in exchange for requiring 4x as much food.

Despite being called a Nuclear stomach, it does not require uranium to craft.
