Embodiment Construction
[0107] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0108] The invention considers the spatial distribution of reactivity feedback, uses the first-order perturbation theory to finely consider the reactivity feedback changes of each node of the fast pair assembly, and calculates the accurate fuel temperature reactivity feedback and coolant density reactivity feedback of each node; proposes the reaction The concept of linear contribution, finely calculate the axial expansion reactivity feedback of each section of the fast reactor component; introduce the mechanical model, calculate the bending offset of the fast reactor component, and accurately calculate the bending reactivity feedback of each section of the component; introduce convective heat transfer The model, which takes into account the effect of the expansion of the control rod drive mechanism on the reactivity, calculates the reactivity fee...
