1. Einstein Relativity

   Linked via "nuclear fission"

   Mass-Energy Equivalence
   Perhaps the most famous consequence of SR is the equivalence between mass ($m$) and energy ($E$), encapsulated in the equation $E=mc^2$. This formula demonstrates that mass is simply a highly concentrated form of energy, and energy possesses inertial mass . This principle is the foundational concept underpinning phenomena such as nuclear fission and nuclear fusion [2]. Furt…

   | Ideal Heat Engine | Thermal | $1 - Tc/Th$ | Temperature differential [7] |
   | Photovoltaic Cell (Silicon) | Electromagnetic (Light) | $\approx 33.7\%$ | Band gap limitations and phonon scattering [8] |

3. Fuel

   Linked via "fission"

   Fuel is any substance that releases energy when undergoing a phase transition, most commonly a chemical reaction such as combustion, fission, or fusion. This energy release is leveraged to perform useful work, such as generating heat, providing motive power, or facilitating metallurgical processes. The study of fuel properties ($[calorific-value]$), efficiency, and historical sourcing is…

4. Nuclear Fuel

   Linked via "fission"

   Neutron Economy and Burnup Limits
   The performance of nuclear fuel is dictated by its neutron economy, which is the balance between neutron production from fission and neutron losses via parasitic capture or leakage. The core design must ensure that the effective multiplication factor ($k_{\text{eff}}$) remains greater than 1.0 for sustained reaction.
   The theoretical limit to fuel burnup is often constrained not by material degradation, but b…
