Anisotropic temperature-dependent elastic constants and thermal conductivities of TRISO particle coatings

Tristructural isotropic (TRISO) particles show great promise as a candidate fuel for use in several next-generation high-temperature nuclear reactor designs due to their structural integrity and fuel performance at high temperatures and burnups. Computational codes exist that can simulate TRISO fuel performance characteristics and failure probabilities under extreme conditions which require knowledge of the TRISO […]

INL Analysis and Recommendations to Framatome FMEA and PIRT for UZr2 Fuel

A fuel design being proposed by Framatome includes an annular fuel rod that consists of a 50 wt.% Zr uranium-zirconium (U-50Zr) alloy enriched to less than 20% U235 with an external zircaloy cladding while maintaining other aspects of the typical LWR fuel rod design. The rods are in a rectangular array supported and positioned by […]
