description: The object of the study is the high-pressure regeneration system at the third power unit of the Kalinin NPP during the modernization of the repair campaign in 2022. The purpose of the study is to analyze the modernization of the system, namely, the replacement of heaters of one type with another. Justification of the rationality of the work performed from the economic and physical side. The following objectives were set as tasks based on the set goal of the study: â¢ To highlight the principle of operation of the high-pressure regeneration system â¢ Description of old and new equipment, the principle of their operation â¢ Perform thermal calculation â¢ Perform an economic calculation Research methods: analytical, statistical, computational and constructive, economic and mathematical The relevance lies in the justification of the work performed, the impact of equipment replacement on the thermal cycle of the station, as well as the visibil-ity of improvements after the installation of heaters.
