\etaDefinition
EN
average number of fission neutrons, both prompt and delayed, emitted per neutron absorbed in a fissionable nuclide or in a nuclear fuel, as specified
FR
nombre moyen de neutrons de fission, instantanés et retardés, émis par neutron absorbé par un nucléide fissile ou par un combustible nucléaire, selon ce qui spécifié
Notes
EN
is equal to the quotient of the macroscopic cross section for fission and that for absorption, both for neutrons in the fuel material.
FR
est égal au quotient de la section efficace macroscopique de fission par celle d'absorption, ces deux sections étant relatives aux neutrons et à la matière combustible.
