Acoustic Emission Weld Monitoring of Nuclear Components

Description: Acoustic emission monitoring augments other nondestructive testing methods and is sometimes applicable when other tests cannot be applied. This is, in part, due to the high sensitivity of acoustic emission monitoring. Acoustic emission monitoring is only sensitive to active flaw-growth, however, and will not detect a flaw in equilibrium. This paper describes the application of acoustic emission monitoring to nuclear reactor fuel pin end closure welds and other weldments of the reactor piping.

Pressure Distribution in Irregularly Bounded Reservoirs

Description: Report issued by the Bureau of Mines over petroleum reservoir pressure distribution. As stated in the introduction, "the purpose of this investigation is to provide the petroleum engineer with the computer techniques to determine quickly the pressure distribution in a petroleum reservoir" (p. 1). This report includes tables, and illustrations.

Cooling Ponds: Survey of the State of the Art

Description: Since the enactment of the Water Quality Act of 1965, there has been an increasing concern over the quality of the nation's waters. Adoption of temperature standards of water bodies, combined with the economics of scale, is resulting in increased use of alternatives to once-through cooling systems, particularly ponds and towers. Approximately 60 steam-electric power plants with capacities greater than 60 electrical megawatts use cooling ponds. This report documents a review of cooling pond technology in which major emphasis was placed on examination of engineering and environmental aspects of design, mathematical and physical modeling, use of sprays, and economics.

Length changes in FTR prototypic cladding irradiated in EBR-II to 1 x 10/sup 22/ N/CM/sup 2/, E > 0. 1 MeV (PIN B-65)(RM-24)

Description: Swelling in prototypic FTR cladding and duct specimens is being determined from a series of three irradiations designed to cover a range of temperatures approximately 800 to 1500/sup 0/F and peak fluences of approximately 1 x 10/sup 22/, 6 x 10/sup 22/, and 1 x 10/sup 23/ n/cm/sup 2/. The length change measurements for the low fluence irradiation have been completed and are summarized in this report. No swelling, only shrinkage, was found in the 20 percent cold worked Type 316 stainless steel cladding specimens. This shrinkage is of the same magnitude and has the same temperature dependency as unirradiated, control samples. Annealed specimens did swell slightly. Details of the experiment and analysis are given.
