AI Thread Summary
Fertile free fuel refers to nuclear fuels that do not contain U238 or Th232, aiming to achieve a conversion factor of zero for complete burning of transuranics. The discussion highlights the importance of including fissile materials like U235, U233, or Pu239 to sustain a nuclear reaction chain. Participants emphasize the need for clarity on the definition and context of fertile free fuel. The conversation suggests that further details are necessary to provide a satisfactory answer. Understanding the composition of such fuels is crucial for their application in nuclear energy.

Hi, everyone what is fertile free fuel ?
 
Engineering news on Phys.org
That's a good question - what have you done to try to find out for yourself?
Presumably you googled the term and found out the nuclear fuels context - since you still don't know, this must not be the one. Or maybe there was something about the answer that was not satisfactory?

You can help us get the right answer for you by providing more detail.
 
Commonly it´s a fuel without U238 or Th232. The mean idea of using this kind of fuels is to reduce the conversion factor to zero in scheme of complete burning of transuranics.

Thank you for your help. is this fuel contain u-235?
 
or any other fissile material

Yes it should have either U235, U233 or Pu239 if you want to maintain a reaction chain.

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...
