PARFUME User's Guide

Abstract

PARFUME, a fuel performance analysis and modeling code, is being developed at Idaho National Laboratory (INL) for evaluating gas-reactor coated particle fuel for prismatic, pebble bed, and plate type fuel geometries. The code is an integrated mechanistic analysis tool that evaluates the thermal, mechanical, and physico-chemical behavior of (tri-isotropic [TRISO]) coated fuel particles and the probability for fuel failure given the particle-to-particle statistical variations in physical dimensions and material properties that arise during the fuel fabrication process. Using a robust finite difference numerical scheme, PARFUME is capable of performing steady-state and transient heat transfer and fission-product diffusion analyses for the fuel. Written in FORTRAN 77, PARFUME compiles in FORTRAN 90 and is easy to read, maintain, and modify. Currently, PARFUME is supported only on Linux platforms.
