The article considers the first stage of designing diversification of professional retraining programs for employees of the nuclear industry in the conditions of digital transformation of the industry. The article justifies the new digital approaches to personnel training. At the project development stage, the general methodological foundations of digital disciplines in knowledge production were established in the form of a "digital methodology," the core of which is the knowledge paradigm of technoscience. The potential of "digital methodology" leads to the development of the mental, social, organizational resources of workers. The worldview platform of the project made it possible to formulate guidelines for the formation of competencies in the diversification of the professional retraining program: the development of critical and analytical thinking, technological literacy, personal growth, communicative initiative, and social responsibility. The authors note that the recognition of the methodological reflection of digital technologies is presented in the publications of researchers in various scientific fields, while the practice of foreign research is more advanced in the development of a quantitative assessment of qualitative indicators, and the domestic tradition is focused on the cognitive aspect of digitalization. But the convergence of approaches is manifested in the diversity of digital learning practices.
