ANP PROlECT PROGRESS REPORT The tube that failed and two adjacent tubes were mounted intact and carefully ground to permit examinations of their longitudinal cross sections as seen against the direction of air flow. The tube that failed is shown in Fig. 3.4.23. The neckdown of the tube wall indicates a tensile fracture similar to that observed2 in York radiator No. 1. Longitudinal cross sections of the two adjacent tubes that were examined are shown in Figs. 3.4.24 and 3.4.25. Incipient fractures may be seen in both these tubes. Three tubes were also taken from corresponding positions on the air exit face and prepared for examination in a similar manner. Only one tube exhibited evidence of incipient fracture, as shown in Fig. 3.4.26. It is concluded that the radiator failed as a result of the initiation of a fracture in a braze alloy fillet by shear forces and the propagation ‘P. Patriarca et a&, ANP Qwr. Prog. Rep. Dec. 10, 1955, ORNL-2012, p 145. of this fracture through the tube wall by tensile forces or combinations of tensile and shear forces during periods of cyclic operation. Since the incidence of incipient fractures was associated exclusively with the presence of support members or plates, it is recommended that these transverse restraints be removed entirely. This can be accomplished, as suggested previously, by using a high-conductivity fin to provide transverse support at 2- or 4-in. intervals3 and modifying the brazing procedure accordingly. The tensile loading contribution to the York radiator failure was attributed at the time of examination to the restraining influence of the support member, which extended up the side of the radiat~r.~ In view of this conclusion, the support members of subsequent radiators, including PWA No. 2, were slit, as shown in Fig. 3.4.20, 3R.
