Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe plutonium-239 breeder reactor is commonly called a fast breeder reactor.
Sodium is used for cooling and heat transfer.
The fast breeder requires a higher enrichment of U-235 than a light-water reactor, typically 15 to 30%.
The reactor fuel is covered by non-fissionable U-238.
No moderator is used in the breeder reactor since fast neutrons are more efficient in transmuting U-238 to Pu-239.
Heavy water is used as a coolant to slow down the neutrons.
