Neutronics Scoping Tool

This is a beta version of our new Neutronics Scoping Tool. Dial in your core dimensions and enrichment and see how critical it is and how much the fuel costs and what the normal power would be at that volume (assuming typical power density). The translucent outer area represents typical shielding required. Read more information about the tool here. Still, this is very approximate and especially overestimates reactivity for small cores. It can give you an idea within like 1-4% dk/k. Please confirm with real calculations.

Assumptions and simplifications in place:

  • Bare cylindrical geometry, no reflector
  • No control rods or burnable poison (somewhat counteracts the former)
  • Vacuum boundary conditions
  • No fuel shuffling (single cycle)
