In the discussion about applying the Nemtab cross section library into the PARCS neutronics code, a beginner seeks guidance on integrating Nemtab data. The user notes that PARCS allows for cross section data input through the XSEC card or the PMAXS in the DEPL card. They possess a Nemtab library with various branches for different fuel temperatures and coolant densities but are unsure whether to input it directly or convert it into PMAX files. Participants are encouraged to share their experiences or solutions regarding this integration challenge. The conversation focuses on the technical aspects of using cross section data in PARCS effectively.

Hello everyone, I am a beginner for PARCS neutronics code. In PARCS we have 2 ways to set the xs data. One is in the XSEC card and the other is using PMAXS in DEPL card. Now I have nemtab xs library with many braches of different Fuel temperatures and Coolant densities. I am confusing that is there a way a can put nemtab directly to PARCS input or do I have to convert nemtab into PMAX files. Please let me know if anyone have experience this issue. Thank you very much!

Thread 'What type of energy is actually stored inside an atom?'

What type of energy is actually stored inside an atom? When an atom is split—such as in a nuclear explosion—it releases enormous energy, much of it in the form of gamma-ray electromagnetic radiation. Given this, is it correct to say that the energy stored in the atom is fundamentally electromagnetic (EM) energy? If not, how should we properly understand the nature of the energy that binds the nucleus and is released during fission?
