    Can You Analyze Reactor Kinetics with Non-Stationary Initial Conditions?

    Astronuc: I understand your last post. OK. From the begining. Let say that I have a subcritical reactor, with the reactivity \rho=-1,5. Than I make a step change in reactivity to \rho=-1. In this example I can calculate the n(t) from the equations from my first post. Before the step...

    Can You Analyze Reactor Kinetics with Non-Stationary Initial Conditions?

    Thanks, Astronuc. Maybe I didn`t quoted my problem very well in my previous post. In a subcritical reactor (k<1) you can say, that before you will do a step change in reactivity you have a stationary state, where dn/dt=0 and dc/dt=0. So you can express c(0) with n(0). In a one group...

    Can You Analyze Reactor Kinetics with Non-Stationary Initial Conditions?

    Hello. I would like to find an analytical solution of the one group point kinetic equations with the external source. I have a critical reactor and I would do the step change in reactivity. I would like to find the solution for n(t). The ONE-GROUP point kinetics equations...

    Six group point kinetic equation

    Hello. I am trying to solve the following 7 equations: dn(t)/dt=ρ-β/l n(t)+∑[SIZE="1"]6i=1 λ[SIZE="1"]iC[SIZE="1"]i+Q[SIZE="1"]0/l dCi(t)/dt= β[SIZE="1"]i* n(t)/l- λ[SIZE="1"]iC[SIZE="1"]i. Where Q[SIZE="1"]0 is constant extra source with neutrons per second. Lets say that I have...

    Six group point kinetic equation

    Does anyone have any experience with numerical solution of the 6 group point kinetic equation, with the step reactivity change? Anyone? Thanks.

    Six group point kinetic equation

    Hello. I would be very thankful with some help with the numerical solution of the six group point kinetic equations, with the constant reactivity (step change). I would like to do this with the Mathematica. Thanks. Dusan
