Per GWe-year, a 3700 MWt Sodium Fast Reactor produces 558 kg and consumes 789 kg of fissile plutonium in the core while producing 455 kg and consumes 34 kg of fissile plutonium in the reflector (breeding blanket). Assume 200 MeV per fission and a capture-to-fission ratio of 0.1405.

Question

Per GWe-year, a 3700 MWt Sodium Fast Reactor produces 558 kg and consumes 789 kg of fissile plutonium in the core while producing 455 kg and consumes 34 kg of fissile plutonium in the reflector (breeding blanket).  Assume 200 MeV per fission and a capture-to-fission ratio of 0.1405.

What is the overall breeding ratio for this reactor?

bobpursley · Answer

The cycle used 833kg, and produced 1013kg breeding ratio: 1013/833=1.216
