Dynamics of Fluid Fuel Reactors in the Presence of Periodic Perturbations

Figure 1

Behavior of the neutronic flux during the transit of the fissile lump. Two energy groups are considered (higher-level flux corresponds to the first group) and the solution is plotted at different instants during the circulation period.

(a) 𝑡=0 seconds (unperturbed system)

(b) 𝑡=2 seconds

(c) 𝑡=4 seconds

(d) 𝑡=8 seconds
