Using Solutions of Adjoint Problems for Calculation and Numerical Simulation of Measurements of Large Reactivity

Autor: A. I. Popykin, N. M. Zhylmaganbetov, A. A. Smirnova, V. I. Kulikov

Publikováno v: Physics of Atomic Nuclei. 83:1227-1241

The article discusses the relationship between the calculated reactivity ρ = 1 – 1/keff obtained from steady-state calculations and its measured analog. In VVER reactors, the measured reactivity is determined from the readings of a reactivity mete
