Abstract
The bank of Kalman filter method for reactivity and neutron density estimation originally suggested by D`Attellis and Cortina is critically overviewed. It is pointed out that the procedure cannot be applied reliably in such a form as the authors proposed, due to the filter divegence. An improved method, which is free from devergence problems are presented, as well. A new estimation technique is proposed and tested using computer simulation results. The procedure is applied for the estimation of small reactivity changes. (R.P.) 9 refs.; 2 figs.; 2 tabs.
