The investigation reported here was conducted by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in 2006. The investigation addressed carbon tetrachloride contamination on the former CCC/USDA grain storage facility at Ramona, Kansas. The results clearly demonstrate that only minimal contamination is associated with the past use of carbon tetrachloride on the former CCC/USDA property. No soil contamination was detected at concentrations above Kansas Department of Health and Environment (KDHE) risk-based screening level (RBSL) Tier 2 standard of 200 {micro}g/kg for the soil-to-groundwater protection pathway. Carbon tetrachloride concentrations in groundwater above the RBSL and maximum contaminant level (MCL) value of 5.0 {micro}g/L were detected in only two samples, collected at adjacent locations on the southeast part of the property. The relatively low concentrations detected and the limited areal extent of the contamination demonstrate that no imminent threat exists on the former CCC/USDA property to warrant remediation. The soil and groundwater contamination detected on the former CCC/USDA property is clearly separate from contamination detected at off-site locations. The carbon tetrachloride and chloroform contamination in groundwater (at concentrations above the RBSL and MCL value) associated with past activities on the former CCC/USDA property is contained within the property boundaries. …

The gas-cooled fast reactor (GFR) is one of six advanced nuclear energy systems being studied under the auspices of the Gen IV International Forum (GIF). In a bilateral International Nuclear Energy Research Initiative (I-NERI) project French and U.S. national laboratories, industry, and universities are collaborating on the development of the GFR. This effort is led by the ANL in the U.S. and the CEA in France. Some of the attractions of the GFR include: (1) Hard spectrum and core breeding ratio, BR {approx} 1. These features allow minimal waste production, improved transmutation capability, optimal and flexible use of natural resources, potentially better economy (because of use of higher power density relative to current thermal gas-cooled systems), and improved non-proliferation (no fertile blanket); (2) Temperature resistant fuel and structure elements that are favorable to tight fission product confinement and system operation at high temperature; (3) High temperature and transparent helium (He) gas coolant that allows a high thermodynamic conversion efficiency, other energy applications (e.g., hydrogen production), and ease of in-service inspection and repair; and (4) Possible direct energy conversion cycle leading to a simpler design, increased conversion efficiency, and lower investment costs. The French strategy for advanced systems includes the development …
