Abstract

Abstract

In the burnup calculation of the reactor core, due to the large difference in the reaction cross sections and lives of nuclides in the evaluation nuclear database, the burnup matrix has large scale and strong rigidity. In order to reduce the scale of burnup matrix and improve the ill conditioned degree of matrix, it is necessary to study the burnup chain compression algorithm suitable for various core design and R & D requirements, and form a compression burnup chain and database. First, the nuclide selection criteria are established, and the nuclide importance is sorted and screened according to the contribution rate of each nuclide to neutron absorptivity and important nuclide nucleon density. The dual-restricted burnup chain compression algorithm based on neutron absorption rate and contribution rate of important nuclide production is studied, and the development of related program modules is completed. Through the calculation and analysis of Kylin-2 program database compression, the feasibility of the burnup chain compression algorithm is verified. The use of compression database can greatly reduce the calculation time and improve the calculation efficiency on the basis of keeping the original calculation accuracy. Through the research of burnup chain compression algorithm and the implementation of compression database, it provides technical support for making compression database from the evaluation database.
