| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Quantum Physics (quantum_physics) | enabling | 74% | expert_inference | Nuclear fission is a nuclear process explained by modern nuclear and quantum physics, though the DOE source states the process rather than a named prerequisite chain. |
|
| Scientific Method (scientific_method) | enabling | 58% | expert_inference | Fission discovery depended on experimental nuclear chemistry and physics methods, not a one-step dependency on a generic method node. |
|
| Advanced Chemistry (advanced_chemistry) | enabling | 66% | expert_inference | The 1938 discovery involved radiochemical interpretation of uranium products, making chemistry an enabling discovery context. |
|
| Relativity (Special & General) (relativity_special_general) | common_dependency | 52% | expert_inference | Relativity explains mass-energy equivalence for released energy, but the physical splitting process does not require relativity as a hard operational component. |
|
| Isotope Separation (isotope_separation) | commercial_or_scaling_dependency | 62% | review | Isotope separation and enrichment matter for many nuclear fuel cycles and weapons programs, but fission itself and some reactors do not require it as a universal prerequisite. |
