Four factor formula
text:
The four-factor formula, also known as Fermi's four factor formula is used in nuclear engineering to determine the multiplication of a nuclear chain reaction in an infinite medium. The symbols are defined as:
- ν, ν f and ν t are the average number of neutrons produced per fission in the medium.
- σ f F and σ a F are the microscopic fission and absorption thermal cross sections for fuel, respectively.
- Σ a F and Σ a are the macroscopic absorption thermal cross sections in fuel and in tota
