The decontamination and decommissioning of the Department of Energy Rocky Flats site has resulted in a number of large waste items that need to be shipped to waste collection areas. However, in order to transport these items, they need to be size-reduced and packed into DOT-approved containers such as standard industrial packaging (IP) waste containers. The size reduction process costs time and money while exposing workers to potential health and safety risks. Spray-on polyurea coatings have the potential of allowing large items to be encapsulated by the coating and transported without having to size-reduce the items. The Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU) recently performed an engineering analysis that includes mechanical testing and small-scale drop tests to determine the feasibility of using a spray-on polyurea coating for shipment of large, low-level waste items instead of using standard IP waste containers.

Technology development activities are being conducted by the Department of Energy, Office of Civilian Radioactive Waste Management to support spent nuclear fuel and high-level radioactive waste transport to the federal repository at Yucca Mountain, Nevada in 2010. The paper discusses the motivation for pursuing transport technologies for a private sector operated transportation program, and describes some of the current technologies being pursued.

Household System

The introduction of photovoltaic solar household systems (PV/SHSs) into rural electrification programmes in the developing world has brought in its wake dissemination/adoption and sustainability challenges. In order to stimulate wider dissemination, some authors have advocated the greater involvement of the private sector. While the private sector has played a key role, this paper argues that effective government institutional and policy frameworks are the most pivotal elements in the push to disseminate PV/SHSs to the rural poor in the developing world. Using two case studies, the paper contextualises the link between what, at present are inadequate government institutional and policy frameworks and the low level of PV/SHS dissemination in rural Ghana.

Abstract Reanalysis and operational analysis products are routinely used as the best estimates of the atmospheric state for operational and research purposes. However, different models, assimilation techniques, and assimilated datasets lead to differences between products. Here, such differences in the distribution of low-level water vapor over summertime West Africa are analyzed, as reflected in the zonal mean position of the leading edge of the West African monsoon [the intertropical discontinuity (ITD)] using five reanalyses [NCEP–NCAR, NCEP–Department of Energy (DOE), the Modern-Era Retrospective Analysis for Research and Applications (MERRA), the Climate Forecast System Reanalysis (CFSR), and the Interim ECMWF Re-Analysis (ERA-Interim)] and two operational analyses [Global Forecast System (GFS) and ECMWF] during the 11 monsoon seasons (April–September) from 2000 to 2010. Specific humidity differences regularly reach 50% of the mean value over areas spanning hundreds of kilometers and often coincide with northward excursions of the ITD that last several days and bring unusual rainfall to the Sahel and Sahara. The largest disagreements occur during the southward retreat of the ITD and are connected with anomalously high values of aerosol optical depth, consistent with the production of haboob dust storms. The results suggest that known errors in the representation of moist convection and cold pools may contribute to the identified disagreements. A large reduction in disagreement occurs in 2006, when upper-air observations were enhanced during the African Monsoon Multidisciplinary Analysis (AMMA) campaign, pointing to an insufficient observational constraint of the (re)analyses in other years. It is hoped that this work will raise awareness of the limited reliability of (re)analysis products over West Africa during the summer, particularly during northward surges of the ITD, and will instigate further work to improve their quality.
