In order to solve the problem of water exchange minimization in the primary loop of VVER-1200 reactor operating in load-following mode, we chose the dynamic programming method (DPM). However, this method is very expensive in terms of RAM and computin

Neutron field reconstruction with consideration of the spatial correlation of the cross-section value error

Autor: N. V. Schukin, A. A. Semyonov, A. A. Druzhaev

Publikováno v: Physics of Atomic Nuclei. 77:1604-1610

A method for reconstructing the neutron field in a reactor with consideration of the spatial correlation of the cross-section value error was analyzed. It was shown that this method is more accurate than the classical approach to reconstruction. An e

Features of the application of the Monte Carlo method to calculations for large RBMK reactors and to model correction on the basis of data from in-core detectors

Autor: V. E. Druzhinin, N. V. Schukin, I. E. Ivanov, M. I. Gurevich, D. A. Lysov, S. A. Bychkov, Yu. V. Shmonin

Publikováno v: Physics of Atomic Nuclei. 77:1629-1639

Statistical errors in sampling neutron fields in physically large systems like an RBMK are analyzed both qualitatively and quantitatively. Recommendations concerning the choice of parameters for calculations are given. A new procedure for Monte Carlo

Using the procedure of spectral projection for reactivity determination in physically large nuclear reactors

Autor: Alexey Cherezov, N. V. Schukin, D. A. Solov’yov, A. A. Semyonov

Publikováno v: Physics of Atomic Nuclei. 74:1900-1907

The reactivity determination methods which are based on the neutron field reconstruction procedure and the spectral-projection method are analyzed. The approximate methods of reactivity determination which can be used in practice are offered. The eff

Reconstruction of radio-ecological model parameters based on the results of monitoring the radiation situation in Mazovia after the Chernobyl accident (based on the «Warsaw» scenario of the IAEA EMRAS project)

Autor: O. K. Vlasov, I. A. Zvonova, P. Krajewski, N. V. Schukina, S. Yu. Chekin, K. A. Tumanov

Publikováno v: Радиационная гигиена, Vol 13, Iss 4, Pp 26-33 (2020)

The paper analyzes the consistency of the input data of the radioecological model: the results of measurements of 137Cs and 131I concentrations in the atmosphere after the Chernobyl accident in Warsaw, the meteo-data on precipitation during the main
