Çekmece Nuclear Research Center.http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/589TENMAK D.N.. 10304Starting from the general transport equation and within the limits of P1 approximation, a set of coupled second order partial integro-differential equations is obtained. These equations consider the effect of m groups of retarded neutrons and contain both the first and the second derivatives of the neutron fluxes with respect to the time variable.enginfo:eu-repo/semantics/openAccessNeutronsNötronlarNeutron diffusionNötron difüzyonureport
