Prepare in Depth Demonstration

[MicahGale]

As preparation for the M&C 2025 and general user resources we need to develop in depth demonstration/tutorial jupyter notebooks.

Here are my thoughts:

1. Base it on version 1.0
2. Cover the following topics/objects:
   • MCNP_Problem
   • NumberedObjectCollection
   • Cell
   • Surface
   • Material
3. To accomplish this I think we should start with a simple model and have a series of tasks that improve and complicate the model. Each task is probably a separate notebook with an answer key of a notebook/completed model. This would allow users to get back up to speed.
4. For this a Westinghouse 17x17, GE 9x9, etc. might be good to model. Though this has some export control concerns. One option would be to use non-sense values, or to get all the information from a single public source (combining multiple public sources gets complicated)
5. Tasks
   • Start with a simple pin cell.
   • Build the lattice cell and make a fuel assembly that's just repeated pins.
   • Switch to add instrumentation/ control rod holes using complicated fills
   • Fix material definitions that use 2600.50c, etc.
   • Fix material compositions for enrichment zoning, gad BP, etc.
   • Add an IFBA cell
   • Update model to be full height
   • Add axial and radial discretization of all fuel pins to allow independent depletion
