    Error Mcnp
Click For Summary
The fatal error in MCNP related to cell 27 occurs when the cell description exceeds the 1000-word limit. To resolve this issue, users should simplify the cell description by breaking it into smaller, more manageable Boolean expressions or using simpler cells. The specific solution will depend on the geometry of the problem being modeled. Addressing this error requires a careful review of the cell's description to ensure it adheres to MCNP's constraints. Simplifying the cell will help eliminate the error and allow for successful execution of the simulation.

I am running MCNP. It gives a error massage : fatal error description of cell 27 uses 1098 words. 1000 words max.

I am not able to resolve this. If anybody can explain me about this error and how to correct it. regards

Is there additional detail you can provide here that might assist someone who uses MCNP to help you with this?
 
That happens when the cell description is too long. MCNP has a limit on that. Correcting this depends entirely on your problem geometry. If you can, break that cell into simpler Boolean expressions or different simpler cells.
 

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?
