Candu heat transport systems
Webcooled CANDU have been chosen with coolant core-mean temperatures near 400°C and 500°C. These are dubbed Mark 1 and Mark 2 respectively. They are based on heavy or light water coolant at a nominal pressure of 25 MPa. Mark 1 transfers heat from a heavy water primary system to a light water secondary system at 19 MPa and is expected to WebHEAT TRANSPORT CHAPTER OBJECTIVES: Chapter 4: Heat Transport page4-J At the end ofthis chapter, you will be able to describe the following features ofthe CANDU heat …
