LEAD AND LEAD-BISMUTH COOLED FAST REACTORS

12.6.1 LFR (Gen IV)

Lead and lead-bismuth systems are being considered in the GIF programme (The US Generation IV Implementation Strategy, 2003; Figure 12.5). Examples are listed in Table 12.6.

Data from The US Generation fV Implementation Strategy (2003) and IAEA-TECDOC-1289 (2002).

The system is based on natural convection cooling with outlet temperature 550°C. It could be somewhat higher ~800°C subject to improved materials development. It can be used within a long life closed fuel cycle of up to 30 years in some concepts. It is anticipated to be used for electricity production, hydrogen production and actinide management.
