Proposal of new O? oxidation criterion for new types of the Zr1Nb alloy of fuel claddings

Popis výsledku v původním jazyce

This paper deals with oxygen concentration measurements and mechanical testing of nonirradiated modified E110 nuclear fuel cladding tubes exposed to low- and high-temperature steam environment. The oxygen concentrations were measured in the prior ?-phaseregion using two experimental methods (SIMS and TEA). The results of both techniques were compared with satisfactory agreement. Then ring compression tests (RCT) and fractographic analyses of failed ring specimens followed. By correlating the oxygen concentration results with the results of RCT, the oxygen concentration threshold of the ?-phase embrittlement has been assessed (C?,threshold = 0.38 wt%). The tubes exceeding this oxygen concentration in the ?-phase may become brittle. The threshold was compared with the results of other authors with satisfactory agreement. Eventually, the kinetics of the oxygen uptake in the prior ?-phase has been assessed based on the SIMS and TEA results: C? = 128 exp(-10,875/T) t1/3. By implementing th
