History of Laboratory:

The laboratory was created in July 2012. The laboratory includes a sector that supports the operation of the Institute’s Data Processing Center. The data center has the following equipment: K-500 supercomputer, IBM BladeCenter E blade system consisting of 14 and 2-processor HS22 blade servers (156 computing cores), IBM System Storage N6040 storage system, network equipment. Computing resources and software enable full-scale precision Monte Carlo simulations of power reactor cores.

Main directions of scientific research:

  • simulation of nuclear installations, justification of the safety of nuclear facilities at all stages of the life cycle;
  • development of supercomputer and grid technologies for simulation in nuclear physics and high energy physics;
  • research in the field of nuclear physics, particle physics and physics of interaction of radiation with matter;
  • development of methods and means of information, analytical and computational support of work to ensure the safety of nuclear facilities.

The laboratory participates in the implementation of State scientific research programs:

  • State scientific research program “Energy and nuclear processes and technologies” for 2021–2025. Subprogram 1.3 “Nuclear research and technology (theory, experiment, applications)”
  • State program “High-tech technologies and equipment” for 2021–2025. Subprogram 3 “Scientific support for the efficient and safe operation of the Belarusian nuclear power plant and promising directions for the development of nuclear energy”

The laboratory also carries out work on information support for the Institute’s activities, including:

— provides secure authorized remote access to stored information and computing resources;

— carries out construction, reconstruction, repair, development and technical re-equipment of the information and computing base, infrastructure facilities;

— carries out work on the design, development and operation of computer systems, including the use of information security tools.


To assess the safety of various nuclear hazardous systems, the laboratory has at its disposal modern calculation programs developed by leading institutes in different countries. Such programs include:

  • MCU is a universal code for numerical simulation of transfer processes of various types of radiation (neutrons, gamma rays, electrons, positrons) in three-dimensional systems using the Monte Carlo method;
  • SERPENT is a calculation code (based on the Monte Carlo method) designed to calculate burnup, determine the criticality of various systems that contain fissile materials;
  • SuperMC (Super Multi-functional Calculation Program for Nuclear Design and Safety Evaluation) integrated software system for neutronics analysis of nuclear reactors;
  • DYN3D is a program designed to study transient and emergency operating conditions of VVER reactors in three-dimensional geometry;
  • ATHLET, ATHLET/CD – calculation codes for modeling thermal-hydraulic processes in reactor plants;
  • ASTEC is an integrated calculation code for the analysis of accidents with severe core damage;
  • COCOSYS is a calculation code for modeling the development of emergency processes in a containment.
  • RiskA is a reliability assessment and probabilistic safety analysis (PSA) code designed for failure modes and consequences analysis, fault tree analysis, event tree analysis, uncertainty analysis, sensitivity analysis, importance analysis, reliability analysis including human reliability analysis, web data management , fault diagnosis, risk monitoring, etc.
