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.

WebApr 12, 2024 · The inspection of nuclear power plants is an essential process that occurs during plant outages. During this process, various systems are inspected, including the reactor’s fuel channels to ensure that they are safe and reliable for the plant’s operation. The inspection of Canada Deuterium Uranium (CANDU®) reactor pressure tubes, which are … WebSince there is no perfect sealed system, D2O leaks occur from reactor systems. While the moderator system operating parameters are T = 70°C and p = 1.02 bar, the primary heat transport system is hot (T = 260°C) and pressurized (p = 99 bar), so the leaks appear mainly from PHT systems.
