WebOct 1, 2013 · CANDU 6 MAIN HEAT TRANSPORT SYSTEM AGING. Fig. 1 gives a simplified presentation of the HTS components and coolant flow of a typical CANDU 6 reactor. The HTS consists of two “figure-of-8 loops” with four main HTS pumps (P1, P2, P3, P4), four Steam Generators (SG) (B1, B2, B3, B4), and associated headers (HD) … WebThermal hydraulic design ofthe process systems is covered in a separate course. Design and analysis are tightly coupled. The heat transport system (HTS) is ofcentral importance since it is the interface between the heat source and the heat sink. Good HTS performance is essential to reactor integrity, plant performance and safety.
