Lawrence, L A; Trimble, D J

Detailed examinations were conducted on Pressure Tubes 2755 and 1054 removed from N Reactor April 1984 and October 1984, respectively, to evaluate the effects of the operation environment on tube properties. Examinations provided data necessary for the definition of the pressure tube operating envelope and service lifetimes. Examinations reported in Part 1 of this report include dimensional measurements, hydriding, surface oxidation, characterization of inner-surface defects, neutron fluence, and microstructural stability. Mechanical behavior (i.e., fracture toughness) and tensile will be included as Part 2 of this report.
