CANDU reactor - Wikipedia
A heat exchanger, also known as a steam generator, transfers the heat to a secondary cooling loop, which powers a steam turbine with an electric generator attached to it (for a typical Rankine thermodynamic cycle). The exhaust steam from the turbines is then cooled, condensed and returned as feedwater to the steam generator.
Provide the means for the transfer of heat energy from the primary heat transport system, and for the production of steam. Convey the steam produced in the steam generators to the high pressure turbine and other balance of plant loads. Provide for overpressure protection of the steam generator secondary side.
The evolutionary roots of CANDU Steam Generators are traced back to World War II era submarine designs. The now ubiquitous ‘light bulb’ design emerged as higher powers, the use of heavy water, and cost considerations favoured a design that was compact, vertical and exhibited superior heat transfer characteristics, high steam quality
heat transfer and steam generation field, olus apolied research has made it possible TO desi~n nuclear heated s~eam generators for various types of nuclear plants. This paper will review some of the types of units either in service or for which conceptual designs are available and their application to the CANDU Cycle.
Nuclear steam generators in both CANDU reactors and Pressurized Water reactors (PWR's) perform the same function, and are geometrically similar. (See Figure 1). Babcock & Wilcox Canada has supplied more than 200 steam generators to CANDU reactors in Canada, and worldwide, and is also
CANDU reactor - Energy Education
This useful area is known as the steam generator, and it acts as a heat exchanger. The hot heavy water flows through tubes inside of the steam generator, which contains ordinary water. The heat from the heavy water boils the ordinary water into steam, which can then be sent to a turbine to generate electricity. Steam Generator
The steam generator (and the associated heat duty diagram) is the central node of the station. It is the steam generator that dominates the overall plant dynamics.

Session 3 is about the Heat Transport System, which in CANDUs uses heavy water to transfer the energy released by the nuclear fuel in the reactor to generate steam to drive the turbine and generator. You will learn the key features of the Main Circuit, how the pressure and inventory of heavy water is controlled in the heat transport system.
