Thanks for the quick reply Astronuc!
The question is actually from the textbook: "Fundamentals of Nuclear Reactor Physics" By Elmer E. Lewis
There is no information on the enrichment nor are there any given β values for U-238
Hmmmm.......I think I may have found something.
I've found that "β = ∑(Pi*βi)" where Pi is the fraction of power produced by isotope i.
If this equation is true, then would the β at beginning be equal to 100% β(Uranium) and β at end equal to 70% β(Uranium) + 30% β(Plutonium)??
But then which β...
Hi guys, I have a question that I can't seem to wrap my head around.
This is the question:
A power reactor is fueled with slightly enriched uranium. At the end of core life (i.e., when it is about to be batch refueled), 30% of the power comes from the fissioning of the built up Pu-239...
1. Homework Statement
reactor consists of nested spheres (sorry, this is my first time posting):
Sphere 1 --> Lead target with radius of R0 (Target-region)
Sphere 2 --> Actinide Fuel surrounding lead target; has outer radius of R1 (A-region)
Sphere 3 --> Reflector surrounding the fuel with...
I am supposed to derive the neutron flux equation provided for region A of my reactor. Just wondering if anyone can help me out since I stuck on the derivation for [1/r - 1/R2]; S/4πD aspect is very similar to a solving the constant for a point source spherical reactor
Here is my...
