Editing Breeder reactor (section)

=== Doubling time ===
The [[doubling time]] is the amount of time it would take for a breeder reactor to produce enough new fissile material to replace the original fuel and additionally produce an equivalent amount of fuel for another nuclear reactor. This was considered an important measure of breeder performance in early years, when uranium was thought to be scarce. However, since uranium is more abundant than thought in the early days of nuclear reactor development, and given the amount of plutonium available in spent reactor fuel, doubling time has become a less important metric in modern breeder-reactor design.<ref>{{cite web |title=Who is afraid of breeders? |publisher=Indira Gandhi Centre for Atomic Research, Kalpakkam 603 102, India |first1=Placid |last1=Rodriguez |first2=S.
