Doubling time for Breeder Reactor.

  1. Oct 12, 2011 #1
    What is the doubling time for breeder reactor, and how its related to the , Power , Original Fissile load ,and The breeding ration "BR" ?
    if there is any online sources or recommended books about the subject for further reading.

    If the breeding ratio is 1.2 then it would take approximately 4 cycles to end up with double the feed (1.2^4 = 2.07). The breeding ratio is not related to the power of the reactor, only its nuclear design characteristics.

    Is there an expression (formula) of the doubling time in terms of the breeding ratio ?

    Find a copy of Fast breeder reactors By Alan Edward Waltar, Albert Barnett Reynolds

    otherwise see here -

    See Chapter 7, Sections 7-8.

    The doubling time depends on a number of factors, such as the fuel form (oxide, carbide, metal), power density, batch size, . . . .

    There are some simple equations, e.g., dM/dt = λM, but the λ is a function of the aforementioned variables.
