This paper emerged from discussions during and after the spring 2005 SfAA session on anthropology and nanotechnology. The three authors have worked for many years in substantially different institutional settings. Wolfe has worked at Oak Ridge National Laboratory (ORNL), owned by the U.S. Department of Energy and currently managed by UT-Battelle, LLC, for a generation. David has resided at Michigan State University's anthropology department for even longer. Sherry is the relative newcomer, having worked at Intel for 9 years (after 2 years at Microsoft). When talking about the nanotechnology-related work we are, are endeavoring to, or are interested in pursuing, it became clear that our institutionally grounded perspectives varied substantially. Moreover, despite some commonalities, the ways in which we do or would engage in nanotechnology research also diverge. This article is a formalized expression of those commonalities and differences, and is indicative of the range of ways in which anthropologists may participate in research surrounding this potentially revolutionary set of technologies.

Abstract CROLOY 9V is a ferritic steel modified with columbium. It was developed at Oak Ridge National Laboratory under contract from the U.S. Department of Energy (DOE). Compared with Croloy 9M (the 9Cr-1Mo alloy) Croloy 9V provides improved strength, toughness and fatigue life with good oxidation and corrosion resistance at elevated temperatures. The alloy should be of interest to designers of a wide variety of equipment used to produce energy. Impressive test data indicate that Croloy 9V is capable of meeting the requirements of a variety of other applications. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-402. Producer or source: Babcock & Wilcox Company.

The U.S. Department of Energy is reducing various risks through its Office of Industrial Technologies (OIT), which shares the cost of developing and implementing technologies that promise to save energy, reduce emissions, and increase productivity of the US steel industry. The OIT signed a compact with the American Iron and Steel Institute and the Steel Manufacturers' Association in May 1995 to collaborate with the U.S. steel industry on three critical research and development areas: process efficiency, recycling, and environmental engineering. Researchers at Oak Ridge National Laboratory in Tennessee developed the nickel aluminide alloy for the rollers, which were centrifugally cast by Sandusky International in Sandusky, OH. This material has superior temperature resistance, which gives it longer service life in the annealing furnace than conventional stainless steel. A phosphor-based sensing technology being tested at Burns Harbor will enable steelmakers to accurately measure the temperature of highly reflective steel strips whose emissivity can skew the readings of optical pyrometers.

The U.S. Department of Energy (DOE) National Nuclear Security Administration (NNSA) is shipping, for disposition purposes, bulk quantities of fissile materials, primarily highly enriched uranium (HEU). The U.S. Department of Transportation (DOT) specification 6M container has been the workhorse for NNSA and many other shippers of radioactive material since the 1980s. However, the 6M does not conform to the packaging requirements in the Code of Federal Regulations (10 CFR 71) and, for that reason, is being phased out for use in the DOE secure transportation system by the end of 2006. BWXT Y-12 developed and licensed the ES-3100 container to replace the DOT 6M. The ES-3100 was certified by the Nuclear Regulatory Commission (NRC) in April 2006. The process of deploying the new package began in June 2005 and is planned to be completed in July 2006. The package will be fully operational and completely replace the DOT 6M at the Y-12 National Security Complex (Y-12) by October 2006. This paper reviews the deployment process and the mock loading station that was installed at National Transportation Research Center (NTRC) of Oak Ridge National Laboratory. Specialized equipment, tools, and instrumentation that support the handling and loading operations of the ES-3100 are described in detail. Loading options for other user sites are explored in preparation for deployment of this new state-of-the-art shipping container throughout the DOE complex and the private sector.
