Hi,
up to this day I thought that endothermic and threshold reactions are equivalent. I mean each endothermic reaction must be threshold and each threshold reactions must be endothermic. But I think I was wrong.
Here is example (from this source Q-value):
10B(n,2*alpha)T
This threshold...
First, fuel temperature changes cannot be neglected. Reactivity feedback, Δρ/Δ% power, comes primarily from changes in fuel temperature. All you have to know is the total power coefficient, which includes both, the change in moderator temperature and fuel temperature:
Total power coefficient of...
Hi, you wrote about pressure drop in fuel assemblies. But you have to specify, whether you mean pressurized water reactors (single phase flow) or boiling water reactors (two-phase flow).
In general, total fuel assembly pressure drop is formed by fuel bundle frictional drop (dependent on...
