# Computational Methods for Reactor Physics (Core Simulation)

• Astronuc
In summary, the conversation discusses the topic of neutronics or reactor physics methods, their various applications, and how they involve solving equations related to neutron transport or diffusion. The choice of method depends on the specific application, and resources such as MIT's OpenMOC Method of Characteristics Code and RSICC's computer code collection WIMS-D5 are available for further exploration.

The question of neutronics or reactor physics methods has come up at various times and with respect to different aspects. I thought it would be worthwhile to explore various methods, the technology and their applications.

Broadly, reactor physics calculations involve solving equations related to neutron transport or diffusion in the complex reactor geometry. The calculations are represented by a system of coupled nonlinear partial differential equations, and particularly partial integro-differential equations (or integro-partial-differential equations).

Some methods, e.g., MC or Sn methods are only appropriate for limited applications such as criticality or a time-specific statepoint in a calculation. For depletion calculations, deterministic methods are more appropriate.

MIT's OpenMOC Method of Characteristics Code should be of interest - https://mit-crpg.github.io/OpenMOC/

The choice of method depends on application.

I've posted some links to get started, but I plan to elaborate more on the subject.

hello
I wanted RSICC COMPUTER CODE COLLECTION WIMS-D5
can anyone help me?
thanks a lot
and sorry for interrupt.

RSICC codes can be obtained by eligible individuals from the RSICC website: https://rsicc.ornl.gov/
