Figure 4-3: Curve fits to data of % radial hydrides ( ( . %)) versus uniaxial externally applied tensile stress in the tube’s
circumferential direction for different maximum temperatures from which the specimens were cooled (from [Hardie &
Shanahan, 1975]). The data used in these fits were of specimens from the OD mixed zone of flattened Zr-2.5Nb
pressure tube material, all with hydrogen content of 100 wppm. The OD zone is a region of maximum macroscopic
residual tensile stress. The number beside each curve corresponds to the specimen number in Table 1 of [Hardie &
Shanahan, 1975] and to the number given in the legend showing the maximum temperature from which each of the
specimens was cooled.
