Acoustic emission from beryllium

Description: The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensi… more

Development of a prototype high temperature amplifier for geothermal well logging. Final report

Description: A high temperature amplifier for use in geothermal well logging was developed. This development was based on the use of ceramic vacuum tubes as the active circuit element, since these tubes have the capability to operate in the high ambient temperature environment. The primary goal of this program was to design, build, and deliver a prototype amplifier capable of continuous operation in a 250/sup 0/C environment. A development program designed to meet this goal covered four phases. These phases… more

High-burnup performance of mixed-oxide fuel rods clad in type 316SS of 0. 010- and 0. 015-inch wall thickness. [LMFBR]

Description: Two short mixed-oxide fuel rods of LMFBR design configuration were irradiated to a burnup of approx. 12.5 atom % in GETR. Profilometry at several intervals during the test indicated that the rod with a 0.010 inch thick cladding exhibited a diametral strain of 0.17% per atom % burnup, while the rod with a 0.015 inch thick cladding exhibited a lower diametral strain rate of 0.12% per atom % burnup. These data present the opportunity for analytical methods to evaluate fuel rod dimensional changes … more
