Environmental effects on materials in operating power reactors

Description: This paper reviews several areas in which corrosion problems have occurred and what can be done to help improve future performance: BWR pipe cracking, PWR steam generators, Three Mile Island-thiosulfate contamination, secondary side problems, mechanical damage (Ginna), piping and vessel cracking, turbine cracking, and bolting. The safety and operational issues involved are listed. (DLC)

Optical and environmentally protective coatings for potassium dihydrogen phosphate (KDP) harmonic converter crystals

Description: Potassium dihydrogen phosphate (KDP) crystals have been used as harmonic converters on the Nova laser at LLNL for over six years. All crystals were coated with a single layer, quarterwave AR coating of porous silica with a refractive index of 1.22. This was prepared by a sol-gel process and was applied from a colloidal suspension by spin coating at room temperature. A few crystals were also coated with a methyl silicone coating prior to the application of the AR coating for environmental protec… more

Modeling Collapse Chimney and Spall Zone Settlement as a Source of Post-Shot Subsidence Detected by Synthetic Aperture Radar Interferometry

Description: Ground surface subsidence resulting from the March 1992 JUNCTION underground nuclear test at the Nevada Test Site (NTS) imaged by satellite synthetic aperture radar interferometry (InSAR) wholly occurred during a period of several months after the shot (Vincent et al., 1999) and after the main cavity collapse event. A significant portion of the subsidence associated with the small (less than 20 kt) GALENA and DIVIDER tests probably also occurred after the shots, although the deformation detecte… more

Structural Target Damage Accompanying Sudden Loss of Vacuum

Description: Report discussing the possibility of structural damage which is most likely to lead to dangerous release of radioactive materials, as well as "the effect of sudden loss to vacuum in a device such as that described in "Engineering Analysis, Mark 2 (4-28-51)."

Debris growth sensitivity to launch and cascade rates

Description: Two-component models provide a good description of debris growth from the outset of launch to the present, predictions of future trends, and assessments of their sensitivity. Launch rate reductions produce less than proportional reductions in debris, for reasons that are discussed. The shift of debris to higher altitudes is assessed quantitatively, although the details of the growth are discussed elsewhere.

Surface contamination initiated laser damage

Description: We are engaged in a comprehensive effort to understand and model the initiation and growth of laser damage initiated by surface contaminants. This includes, for example, the initial absorption by the contaminant, heating and plasma generation, pressure and thermal loading of the transparent substrate, and subsequent shockwave propagation, ``splashing`` of molten material and possible spallation, optical propagation and scattering, and treatment of material fracture. The integration use of large… more

Characterization of nodular and thermal defects in hafnia/silica multilayer coatings using optical, photothermal, and atomic force microscopy

Description: Multilayer coatings manufactured from metallic hafnium and silica sources by reactive electron beam deposition, are being developed for high fluence optics in a fusion laser with a wavelength of 1053 nm and a 3 ns pulse length. Damage threshold studies have revealed a correlation between laser damage and nodular defects, but interestingly laser damage is also present in nodule-free regions. Photothermal studies of optical coatings reveal the existence of defects with strong optical absorption i… more
