WebJul 10, 2014 · Fq (z) is the ratio of power density of the pin divided by the power density of the core. This is a 3-D (axial) value. Each pin has a Fq (z) as a function of height, and a peak Fq. If your pin power profile is normalized, you need to first multiply by the assembly's relative power density. Fz is the maximum normalized power for the core ... WebNov 8, 2024 · The zero flux peaking factor is the normalized density gradient, which causes the turbulent particle transport to have zero flux, and it is the normalized gradient a plasma has in steady state if it does not have any internal sources. As it is sensitive to the collisionality, it is suitable for the collision operator tuning. 25 25. C.
WebThe neutron flux distribution in commercial power reactors depends on many other factors such as the fuel loading pattern, control rods position, and it may also oscillate within … WebThe shape of the profiles can be determined by measuring the ratio of the peak flux to the average flux in the distribution. This peaking factor is referred to as the hot channel factor. A hot channel factor of 1.0 would imply a flat flux profile. ... Thus the limitation of the peak flux value in a core is directly related to the hot channel ...
