description: Investigations in the area of heat exchange intensifiers resulted in a choice of effective method for increasing steam generator PGV-1000 performance. The use of inserts in the form of a twisted tape is a perspective solution, based on the analysis of literature sources and experience in the field for 30 years. Thermal-hydraulic calculations were carried out for the steam generator PGV-1000 with and without the use of the selected intensifiers. The results showed that the use of inserts in the form of a twisted tape makes it possible to reduce the steam generator length by 0.67 m, simultaneously increasing the hydraulic resistance of the first circuit by 0.17 MPa. This method of heat exchange intensification offers significant advantages for the PGV-1000 steam generator. Reducing the length of the steam generator helps to save space and simplifies its placement. In this case the increase in water resistance of the first circuit is not critical and can be fairly taken into account when designing the system. The twisted tape inserts provide an intensification of the steam generators working processes, increasing the efficiency of heat exchange. This can be particularly useful if a higher steam generator output is required or space constraints are limited. Thus, the use of twisted tape inserts is a promising and effective solution for intensifying heat transfer in a PHV-1000 steam generator. This method, based on many years of experience and literature sources, makes it possible to improve the system operation, providing reduction of the steam generator length and increase of the hydro-resistance of the first circuit.
