Open Access

Fig. 9.

Neutron scattering cross sections of ²³⁸U in UO₂ calculated at 300 (a) and 1474 K (b) with the Free Gas Model (black curve), the NJOY code using $S_{CLM}^{LEAPR} (α, β)$ $S^{\mathrm {LEAPR}}_{\mathrm {CLM}}(\alpha ,\beta )$ tables generated with its LEAPR module (red curve) and the Crystal Lattice Model based on the α′ correction (blue curve). The red and blue curves are on top of each other.
