1. Nuclear Reactors

   Linked via "heat exchanger"

   Pressurized Water Reactors (PWR)
   In a PWR, the primary coolant (light water) is kept under high pressure (typically 15 MPa) to prevent boiling, even at temperatures exceeding $300^\circ\text{C}$. This superheated, non-boiling water transfers heat via a secondary heat exchanger to create steam for driving turbines. PWRs exhibit intrinsic negative [void coefficient stability](…

2. Surface Area To Volume Ratio

   Linked via "heat exchangers"

   Heat Exchangers
   Industrial heat exchangers are designed to maximize the transfer rate between two fluids. This is universally achieved by employing internal geometries (fins, tubes, corrugated plates) that maximize the exposed surface area within the device's fixed volume envelope. The efficiency ($\eta$) of an ideal passive heat sink is directly proportional to its $\text{SA:V}$ ratio, assuming uniform thermal conductivity within the material.
