Nuclear Fission Reactor Exam Question

[sclatters]

Homework Statement

I have been able to complete all questions apart from part e)

Homework Equations

Beta minus decay involves electron emission
Beta plus decay involves positron emission
Electron capture takes in an electron

The Attempt at a Solution

I believe that because there is an equilibrium quantity of positrons that the beta minus decay mode would be much less likely to happen and that they would start to decay internally. However I am unsure what else could be said and whether my first statement is correct. Any help would be great, thanks!

Have you considered the possibility of positron capture?
