Discussion Overview

The discussion centers around the concept of "fertile free fuel," particularly in the context of nuclear fuels. Participants explore its definition, characteristics, and implications for nuclear reactions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant asks for clarification on what fertile free fuel is.
  • Another participant suggests that the inquirer should provide more context or prior research to facilitate a better answer.
  • It is proposed that fertile free fuel typically does not contain U238 or Th232, with the intent to reduce the conversion factor to zero in the complete burning of transuranics.
  • A follow-up question is posed regarding whether this type of fuel contains U-235.
  • It is stated that fertile free fuel should include fissile materials such as U-235, U-233, or Pu-239 to sustain a reaction chain.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and definitions regarding fertile free fuel, with some agreement on its characteristics but no consensus on its implications or specific definitions.

Contextual Notes

The discussion lacks clarity on certain assumptions regarding the definitions of fertile and fissile materials, and the implications of using fertile free fuel in nuclear reactions remain unresolved.

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.
