Division for Scientific and Technical Validation of Designs

The Division performs a comprehensive reactor plant safety and reliability analysis and scientific-and-technical validation at all reactor plant lifecycle stages.

The tasks of the Technical Validation Division are to:  

  • analyze and validate reactor core physics characteristics, design and composition, the worth of reactivity control elements and systems, neutron instrumentation and instrumentation for monitoring nuclear safety conditions; develop programs and support core physics testing in test facilities and in operating reactors;

  • analyze thermal physical and thermal mechanical processes, strength and lifetime of fuel assemblies and reactor cores in normal operation and emergency modes; optimize and validate design solutions and measures to enhance the technical and economic performance;

  • analyze and validate radiation shielding effectiveness under normal operating conditions and in accidents; analyze radiation exposure during reactor plant operation and in operations with radioactive sources; analyze radiological consequences of accidents including a postulated severe fuel melting accident; analyze and validate the effectiveness of isolation systems; validate siting of nuclear facilities;

  • analyze thermal hydraulics of reactor plant equipment and systems in static, dynamic and emergency modes; validate design solutions for pump and heat-exchange equipment, for normal operation systems and safety systems; develop requirements for the scope and methods of testing the reactor plant systems in test facilities and actual installations; develop design optimization recommendations in terms of thermal hydraulics, thermal cycling, and efficiency of heat removal channels;

  • analyze reactor plant dynamics in normal maneuvering modes, in case equipment fails and shuts down, in design-basis accidents and beyond-design-basis accidents; validate reactor plant automatic control algorithms; develop requirements for automatic systems, related systems and the entire facility; support developing and testing of automatic systems; develop reactor plant computer simulators and virtual power units;

  • perform a strength analysis and validation for reactor plant equipment elements and systems; develop design improvement recommendations to ensure the strength and to meet requirements for inspection and testing methods. Analyze behavior of structures under thermal-cycling, radiation, and dynamic impacts;

  • analyze and validate lifetime characteristics of reactor plant equipment and systems, including beyond the specified parameters; develop methods for predicting the residual life of reactor plant equipment and systems;

  • analyze processes in the reactor and in the containment during the reactor coolant system loss-of-coolant accidents; analytically validate reactor plant safety and emergency core cooling system design and effectiveness;

  • optimize structural elements of reactor plant systems and equipment through model testing; study the features of heat-and-mass transfer processes on the models of reactor plant equipment units; generate a database to verify 3D thermal-hydraulic and mechanical codes.

    The Technical Validation Division bases the implementation of its tasks upon a wide use of computer codes. Most of these codes have been developed by JSC “Afrikantov OKBM”, verified on a vast database of bench-scale and full-scale testing, as well as by operating data, and certified in accordance with the requirements in the safety regulations for the parameter space of the reactor plants under development.

    Nowadays, one of the significant factors for preserving and strengthening the Company’s competitive ability is a wide use of numerical experiment technologies based on an integrated use of 3D thermal-hydraulic analysis (CFD) programs and structure temperature and stress strained state analysis (FEA) programs on super computers. In a number of cases, the use of the technologies makes it possible to replace the full-scale experiment with a numerical one. This provides a unique possibility for the real structures to be studied at full-scale parameters of the medium with obtaining comprehensive and representative data on all ongoing physical processes. Through this, the design work quality is enhanced with simultaneously reducing the time and cost of the work.

    In the engineering practice, industry-specific best-estimate codes are increasingly used. Making calculations by the best non-Russian codes has been mastered and is widely used as alternative calculations to analyze neutronics, radiation shielding, mechanics, thermal hydraulics, and safety.

    On the basis of the accumulated experience, JSC “Afrikantov OKBM” is developing a technology for creating nuclear power plant digital twins. This technology allows an article to be supported at all its lifecycle stages and solves the following tasks:

  • validate nuclear power plant operation modes;

  • support the reactor plant design development and optimization process;

  • check the nuclear power plant equipment configuration and characteristics;

  • check the integrity and sufficiency of control algorithms;

  • select and optimize control laws;

  • train the personnel.
