      The ability to monitor in situ the creep rates following a stress and temperature change made possible the characterization of creep behavior over a wide stress-strain-rate-temperature design space for two model experimental heats, Zircaloy-2 and Zircaloy-2 + 1 wt%Nb, with only 12 test specimens in a day in-pile creep test program.

    A consequence of the interaction of the in-reactor environment with these alloys is the formation of brittle phase Zr hydride, a process that greatly affects the component integrity. In this work we present a experimental study of the hydrogen influence on the Zry-4 mechanical properties at . IS~eta~~urg~ca~EngmeeringBranrhChalkRiverNuclear.

Thermal creep is a vast subject about which many textbooks have been written, however, its contribution to in-reactor deformation of pressure tubes is small once irradiation hardening has occurred.

For an overview of thermal creep in Zr alloys, see the article by Harbottle [26] and for a more detailed account see the book by Franklin et al. [27].Cited by:   Irradiation creep of Zr-alloy nuclear reactor core components affects the reactor performance and also limits the reactor life in cases where those components cannot easily be replaced.
