Abstract

The challenging geopolitical landscape and the imposition of sanctions necessitate a comprehensive overhaul of economic processes within our nation. In response, the Government of the Russian Federation has delineated a roster of products and technologies earmarked for substitution with domestic equivalents in the immediate future. A pivotal focus lies on the import substitution of software. Pursuant to Presidential Decree No. 166 dated March 30, 2022, titled “Measures to Ensure Technological Independence and Security of the Critical Information Infrastructure of the Russian Federation”, effective January 1, 2025, state authorities and procurement entities are prohibited from deploying foreign software on their critical information infrastructure assets.
The spearhead of the IT import substitution initiative in Russia has been assumed by the State Corporation “Rosatom”, which, within the framework of a unified digital strategy aimed at bolstering IT import independence, is focused on fostering collaboration with indigenous small and medium enterprises. A noteworthy initiative within Rosatom's import substitution program, involving SMEs, entails the modernization of existing GEFEST and GEFEST800 PCs. These systems are designed for operational neutron-physical calculations for fast reactors utilizing sodium coolant at the Beloyarsk Nuclear Power Plant – the world's sole station with industrial-scale fast neutron reactors, namely, BN-600 and BN-800.
The overarching objective of this project is to establish a unified cross-platform PC, known as GEFEST-M, based on the current GEFEST and GEFEST800 models. This unified system will incorporate specially developed calculation modules and methodologies, with the future applicability envisaged for reactors like BN-1200 and other BN-type reactor units.
A pivotal attribute of the GEFEST-M project is the shift away from proprietary closed software development tools. Additionally, it underscores the capability to operate seamlessly on computing equipment and operating systems developed domestically.
The developer spearheading the GEFEST-M PC project is an accredited organization in the realm of information technology – LLC “ASU-LEADER”.
