SUMMARY

The discussion focuses on using the Makxsf code for library production in MCNP (Monte Carlo N-Particle Transport Code). The user reports a decrease in keff (effective multiplication factor) at higher temperatures, but an unexpected increase at several other temperatures. They seek assistance in understanding the behavior of keff and request examples of input files for the Makxsf software, which they possess along with the manual.

PREREQUISITES
  • Understanding of MCNP (Monte Carlo N-Particle Transport Code)
  • Familiarity with the Makxsf code for library production
  • Basic knowledge of nuclear criticality safety concepts, particularly keff
  • Ability to interpret simulation results and troubleshoot software issues
NEXT STEPS
  • Research the impact of temperature variations on keff in MCNP simulations
  • Explore advanced features of the Makxsf code for library generation
  • Learn how to create and format input files for Makxsf
  • Investigate common troubleshooting techniques for MCNP and Makxsf
USEFUL FOR

Students and professionals in nuclear engineering, particularly those involved in library production and simulation using MCNP and Makxsf. This discussion is beneficial for anyone seeking to understand the nuances of keff behavior in relation to temperature changes.

I'm studying in the field of library production for code MCNP. I use makxsf Code to do this operation. I have a simple example . I've produced library by makxsf for this simple example. I've encountered some problem now.
keff has decreased in the higher temperatures suitably, but keff has increased in several temperatures after all. And my question is now ,why is increased? I was wondering if you could help me.

I am sorry,
I want to ask you how to use makxsf sofware,
I have the sofware and the manual pdf file
but still confuse how to use it.
could you send some example of makxsf input file
my email is arifisneni@gmail.com
thanks,
