DNFSB to hold public meeting on aging management
The Defense Nuclear Facilities Safety Board, which provides safety oversight of Department of Energy sites, is holding a public hearing on August 14 on benchmarking of best practices in the management of aging infrastructure.
According to the DNFSB, the goal of the hearing is to gather information from relevant organizations on best practices in infrastructure aging management to inform the development of potential safety improvements to DOE programs.

We investigate the ability of light extinction spectrometry (LES) to characterize, at long distances, the size distribution and concentration of dust mobilized by laser cleaning methods (ITER wall detritiation and characterization of deposition layers) or by experiments dealing with a loss-of-vacuum accident. Potentially harmful effects induced by wall proximity, plasma plume broadband emission, and associated shock waves are shown to have a negligible influence on LES measurements, which demonstrates the interest in this optical technique for the aforementioned studies. However, our experimental results, based on aerosols of silica and tungsten powder aggregates, show that the present setup allows the characterization of dust volume fractions of less than [approximately equal]1-10 ppb for a probing length of 1 m (or by extrapolation [approximately equal]0.1-1 ppb for a probing length of 10 m).
