Corrosion and hydriding of irradiated Zircaloy fuel-rod cladding (LWBR Development Program)

Technical Report ·
OSTI ID:6797265

Zircaloy corrosion performance predicted with the CHORT computer program was compared with measured data from 214 out-of-pile LWBR reference Zircaloy-4 tubing specimens, 47 LWBR irradiation test fuel rods, three MELBA fuel rods, and fuel rod cladding from three commercial pressurized water reactors. CHORT calculations compared well with the out-of-pile autoclave test data, but corrosion thicknesses and hydrogen uptake in LWBR irradiation test program fuel rod cladding were less accurately accounted for by the CHORT program due in part to measurement scatter and material variability. Measured corrosion oxide thicknesses for Maine Yankee, KWO, Turkey Point, and MELBA fuel rods were in reasonable agreement with CHORT predictions.
