Nuclear and Radiation Safety| Резюме: | As of 2022, most of the countries involved in the production of nuclear energy are provided with appropriate resources and tools for operational modelling of atmospheric dispersion and real-time dose projection using actual decision support systems and special codes. However, the development of forecasting tools at different historical stages and capabilities of software developers in different parts of the world involves the use of different databases, data providers, numerical meteorological forecast data, libraries on dose conversion factors, etc.
Activities on comparing the modelling results and analysing the effectiveness in the use of radiation forecasting tools are very relevant in the international context and share the fundamental goal of harmonizing the calculation capacity of countries through benchmarking of assessment software with various technical support organizations in the area of emergency preparedness and response.
This paper offers an overview of international practices and the general concept for benchmarking of the modelling box from a single source term to the calculation results in terms of radionuclide concentrations and projected doses. The work explicates the scope of benchmarking parameters, conditions, preliminary systematization, collection, processing of radiation consequences, and Code-to-Code Analysis (CTCA). For the first time, the paper presents experience in developing and applying in-depth analysis: matched-pair analysis (MPA) based on the SSTC NRS experience in the framework of the "Benchmarking on Assessment of Radiological Consequences" (BARCO) international project. |
