Description

Microstructure of high burnup zircaloy-2 fuel cladding irradiated in Ringhals No. 1 reactor up to 60 GWd/t was examined by transmission electron microscope. a-Component dislocation loops, hydrides and intermetallics are observed in plenums, 30 GWd/t burnup specimens and 60 GWd/t burnup specimens. c-Component dislocation loops are observed in 30 GWd/t burnup specimens and 60 GWd/t burnup specimens. The microstructures of radiation damage, hydrides and intermetallics in 30 GWd/t specimens and 60 GWd/t specimens are very similar. Then these features should not directly embrittle the high burnup fuel claddings. (author)
