This page is the beginning of a hands-on tutorial in Serpent that will walk you through the creation of simple pin-cell and assembly geometry models and the use of those models for some reactor physics simulations.

Pre-requisite

Compiled version of Serpent 2

Basics of Serpent input

Explain different (typical) parts such as:

  • Material definitions
  • Geometry definitions
  • Run parameters/options

Infinite homogeneous system

Overview

Basics

Colors in input correspond to:

  • Comments
  • Control words
  • Name definitions
  • Name references

Input for 2D pin-cell geometry
