The following models and codes for technological stages of CNFC are being developed in the frames of "Proryv" project • Mathematical models of technological processes describing physical and chemical, gas/hydrodynamic, kinetic and phase processes occurring in apparatus. The models are focused on reasoning the range of technical parameters under normal, transitional and abnormal modes and on reasoning and optimization of mass-dimensional characteristics of the equipment and calculation of separate units lifetime; • KOD TP code is intended for real-time simulation of the operation of technological schemes in order to define the functionality, controllability and to optimize the technology including control systems and simulation of accidents; • Kinematic model of processing lines is intended for virtual definition of commutated workability both separate processes, nodes and facilities and processing lines in all. Starting, transitional, stationary modes are considered as 4D-models taking into account kinematic and technological features and restrictions. Developing models and codes are currently used when technologies for closing stages of CNFC are designed (preparing initial data for equipment design and construction). Calculation models allow to detect collisions on early stages and to correct technological, design and engineering documentation; to perform polyvariant calculations to define the efficiency of separate nodes and the scheme in whole; to reason technical and design solutions and to evaluate the fission and nuclear materials during all the stages of the technological process including the in-process one. Currently the integrated system of models and codes is being developed for consistent simulation of heterogeneous processes and phenomena that are required to consider under calculating maintaining and reasoning the safety of CNFC technologies. The integrated system includes the existing and newly developed models and codes intended to describe technologic processes and apparatus, nuclear and radiation safety, ignition criteria, combustion, construction and engineering system behavior under critical loading and so on. The use of modern computational systems allows to perform associate calculations with date exchange between different codes from simple engineering to CFD-codes and to provide the solution of the complex problem of CNFC technology simulation.
