Griffin Validation Against SEFOR Isothermal Experimental Data

Overview

This model validates the Griffin against SEFOR (Southwest Experimental Fast Oxide Reactor) isothermal experimental data.
The goal is to assess Griffin’s predictive capability for sodium-cooled fast reactor conditions using high-fidelity transport methods.

Model Description

A fully heterogeneous 3D DFEM-SN Griffin solve was performed for SEFOR cores I-I and I-E.
Multigroup cross-sections were generated using MCC-3.

Impact

This validation improves confidence in Griffin’s predictive accuracy for fast reactor applications, directly supporting advanced reactor design and licensing.
