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...
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...
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...
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...
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.
