The present paper gives a brief review of technique of the isotopic fuel composition changes modeling with ordinary differential equations system describing nuclides transmutation. Suggested algorithms of modeling and calculation of the main parameters for nuclear transformations are based on a directed graph, which improves the speed and accuracy of calculations. The description is given of the designed software system for modeling of radioactive decay transformations and transformations caused by particles flow (neutrons, protons, etc.). The features and functionality of this system are defined.

System distinctive features include, inter alia, simplicity, developed user-friendly interface, high degree of automation of all stages of user work, simulated processes imaging and convenient tools for calculations management and results processing. The described system is aimed at wide range of users from students and post-graduates to university professors and researchers, and can be used to facilitate scientific research and educational process. The proposed system is a convenient assessment tool for the concentration of any isotope in a chain depending on integral flow and time with various original isotopes amounts.

Apart from author developments, current licensed software and visual reference components libraries from leading global producers were utilized for the system creation, which allowed to develop a user-friendly interface and keep abreast of leading software developments. Modelling results are displayed by interactive tables and characteristic curves.
