Nuclear stomach

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. It can be crafted from 15 plasteel and 4 advanced components.

Cancers from this stomach occur on average once every 120 ingame days, on the torso. Without the cancer, the nuclear stomach would otherwise be a direct upgrade of the bionic stomach, the detoxifier stomach, and the reprocessor stomach.

Shocking a pawn with this stomach using EMP will force them to vomit.

Acquisition

Nuclear stomachs can be crafted at the fabrication bench once Artificial Metabolism, which requires a techprint, is researched. They require 15 plasteel and 4 advanced components and a crafting skill of 8.

Alternatively, they can purchased from traders and outlander and empire settlements.

Analysis

The nuclear stomach offers immunity to food poisoning and a dramatic reduction in hunger rate, in addition to the regular benefits as the Bionic stomach, so it can be considered a direct upgrade with the sole exception of the nuclear stomach being sensitive to EMP and cancer risk. The Detoxifier stomach

Like the bionic stomach, it has 125% part efficiency increasing metabolism by 8%. It can also be used to instantly treat gut worms as the new detoxifier stomach replaces the diseased part. With it installed, further infections are also prevented. The increased metabolism from a detoxifier stomach slightly improves the rest rate multiplier by about 8%, meaning the colonist will require less sleep. The detoxifier stomach is a cheaper way to reduce time sleeping than upgrading to a royal bed, however both can be combined.

Unlike the bionic stomach, EMPing a pawn with a detoxifier stomach will force them to vomit. While EMP-wielding enemies are relatively rare, 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 detoxifier stomach on those melee pawns will result in them vomiting and negatively affecting this tactic and others like it.
