7. F modeling

7.1. Behavioral law and material parameters

The law of behavior tested “VISC_IRRA_LOG”, is documented in doc R5.03.09. This is a law of axial creep under irradiation of fuel assemblies. Values of the parameters used:

Settings	\(T=0°C\)	\(T=500°C\)
\(E(T)\)	\(195000\mathit{MPa}\)	\(195000\mathit{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(1.E-5{K}^{-1}\)	\(2.E\mathrm{-}5{K}^{\mathrm{-}1}\)
\(A\)	\(1.28E-1\)	\(1.28E-1\)
\(B\)	\(0.01159\)	\(0.01159\)
\({\mathit{CSTE}}_{\mathit{TPS}}\)	\(0.3540\)	\(0.3540\)
\({\mathit{ENER}}_{\mathit{ACT}}\)	\(5000.\)	\(5000.\)

The irradiation values as a function of the times are as follows:

INST	IRRA
\(0\)	\(0\)
\(1\)	\(2\)
