Nuclear energy (AQA A-Level Physics): Flashcards

Fission triggered by neutrons in U-235 nuclei

150-200 MeV

At least one neutron per fission causes another fission

Approximately $2$ MeV

Much less than $1$ eV ($\ll 1$ eV)

Slows fast neutrons to thermal speeds

Regulate fission rate by absorbing neutrons

Exactly one neutron per fission causes another fission

Minimum fuel mass for self-sustaining chain reaction

Transfers heat from reactor core
