Problem 6.288

How many neutrons are there in the hundredth generation if the fission process starts with \(N_{0}=1000\) neutrons and takes place in a medium with multiplication constant \(k=1.05 ?\)

Reveal Answer
N=N0ki1=1.3105, where i is the number of generations N=N_{0} k^{i-1}=1.3 \cdot 10^{5}, \text { where } i \text { is the number of generations }
