The steam generating heavy water reactor: design and operational experience

This article surveys the design and operational experience of the commercial SGHWR (CSGHWR) reactor which is based on the Winfreth SGHWR reactor. The main parameters are given. A brief discussion of the fuel cycle, reactor control, emergency shutdown, plant radiation levels and safety features is presented. The layout and containment of the reactor is discussed with emphasis on the CSGHWR fuel stringer and the experience gained with the Winfreth reactor. Finally, attention is paid to core vessels and the reactor coolant circuit
