Doubling time for Breeder Reactor.

AI Thread Summary
The doubling time for a breeder reactor is influenced by the breeding ratio (BR), which determines how quickly the reactor can produce more fissile material. For a breeding ratio of 1.2, it takes approximately four cycles to double the initial feed. The breeding ratio is not related to the reactor's power output but rather its design characteristics. Doubling time can be expressed through equations that consider various factors, including fuel type and power density. For further reading, "Fast Breeder Reactors" by Alan Edward Waltar and Albert Barnett Reynolds is recommended.

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.
Thanks.

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 ?

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.
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
