Abstract

Accumulation of Pu(IV) in head extractors of the mixer-settler type as applied to two different flowsheets of NPP spent fuel reprocessing was simulated under dynamic and steady-state conditions using a mathematical model of extraction. Comparison of the calculations showed that the maximal accumulation of Pu in the head extractor is independent of the calculation procedure and is determined by the features of the extractor flowsheet. However, dangerous accumulation of Pu according to calculations for steady-state conditions (extreme mode of extraction) occurs at smaller deviations of the flow rates from the nominal values, as compared to calculations for the dynamic conditions (above-extreme extraction mode). Accumulation of Pu to high concentrations under steady-state conditions requires a longer time to attain the equilibrium, whereas under dynamic conditions Pu is accumulated considerably faster.
