Actinide Burner Conversion Rate: Fissile vs. Transuranic

AI Thread Summary
The discussion centers on the definitions of conversion rates for actinide burners, specifically distinguishing between fissile and transuranic (TU) materials. The conversion rate is defined in two ways: fissile produced/fissile consumed and transuranic produced/transuranic consumed. There is ambiguity regarding the correct terminology for these rates, as well as how they should be classified in relation to fast reactors (FRs). It is suggested that TU conversion rates are typically greater than fissile conversion rates, but scenarios may exist where this is not the case, potentially affecting classification. The conversation highlights the need for clarity in definitions and classifications within nuclear engineering literature.

Folks,

I was reading the Cacuci Handbook of Nuclear Engineering, and he defines two times the conversion rate, once as:

C= fissile produced/fissile consumed

but later as :

C= transuranic produced/transuranic consumed

and said that the breeding rate is the former but for fissile.

Anyone knows which is the correct unequivocal name for the rate of an actinide burner? It has a rate for fissile and another for transuranic how I should call them?

Thanks,

Hernán

Cacuci is the editor of "Handbook of Nuclear Engineering." There are individual authors of the various chapters, e.g., Paul Turinsky on "Core Isotopic Depletion and Fuel Management," pp. 1241-1312.

It would help if one identifies the specific sections.

The term 'actinide' burner usually refers to TU nuclides, but could also include Th and U, as well as Np and Pu, which are of course, TU elements. However, given that use of Th is limited, actinide burners would focus mainly on U, Pu, Am, Cm.

The calculation of conversion ratio will be based on what fuel materials the system incorporates.
 
Astronuc,

Thanks, you are right that Cacuci is just the editor. May be each author has a different definition.

My problem it´s with FRs classification, usually they are classified based on the conversion rate:
*<1 burner
*close 1 converter
*>1 breeder

Now If we compare the numbers for fissile conversion rate (C) vs TU conversion rate (T) I think that always T > C
But could exist a situation where T < C, or where the classification change if we choose T or C to classify?

Thanks in advance,

Hernán
