Testimony issued by the Government Accountability Office with an abstract that begins "Rail transit generally has been one of the safest forms of public transportation. However, several recent notable accidents are cause for concern. For example, a July 2009 crash on the Washington Metro Red Line resulted in nine deaths. The federal government does not directly regulate the safety of rail transit. Through its State Safety Oversight program, the Federal Transit Administration (FTA) requires states to designate an oversight agency to directly oversee the safety of rail transit systems. In 2006, the Government Accountability Office (GAO) issued a report that made recommendations to improve the program. The Department of Transportation (DOT) is planning to propose legislation that, if passed, would result in a greater role for FTA in regulating and overseeing the safety of these systems. This statement (1) summarizes the findings of GAO's 2006 report and (2) provides GAO's preliminary observations on key elements DOT has told us it will include in its legislative proposal for revamping rail transit safety oversight. It is based primarily on GAO's 2006 report, an analysis of the Administration's proposal through review of documents and interviews with DOT officials, and GAO's previous work on …

The Laser Inertial Fusion-based (LIFE) engine is an advanced energy concept under development at Lawrence Livermore National Laboratory (LLNL). LIFE engine could be used to drive a subcritical fission blanket with fertile or fissile fuel. Current LIFE engine designs envisages fuel in pebble bed form with TRISO (tristructural isotropic) particles embedded in a graphite matrix, and pebbles flowing in molten salt Flibe (2LiF+BeF{sub 2}) coolant at T {approx} 700C. Weapons-grade plutonium (WGPu) fuel is an attractive option for LIFE engine involving the achievement of high fractional burnups in a short lifetime frame. However, WGPu LIFE engine operating conditions of high neutron fast fluence, high radiation damage, and high Helium and Hydrogen production pose severe challenges for typical TRISO particles. The thermo-mechanical fuel performance code HUPPCO (High burn-Up fuel Pebble Performance COde) currently under development accounts for spatial and time dependence of the material elastic properties, temperature, and irradiation swelling and creep mechanisms. In this work, some aspects of the thermo-mechanical response of TRISO particles used for incineration of weapons grade fuel in LIFE engine are analyzed. Preliminary results show the importance of developing reliable high-fidelity models of the performance of these new fuel designs and the need of new experimental …

The overall objective of the EM-31 Rheological Modifiers and Wetting Agents program is to utilize commercially available rheology modifiers to increase the solids fraction of radioactive sludge based waste streams, resulting in an increase in throughput and decreasing the overall processing time. The program first investigates the impact of rheology modifiers on slurry simulants and then utilizes the most effective rheology modifiers on radioactive slurries. The work presented in this document covers the initial investigation of rheology modifier testing with simulants. This task is supported by both the Savannah River National Laboratory (SRNL) and Pacific Northwest National Laboratory (PNNL). The SRNL EM-31 task, for this year, was to investigate the use of rheology modifiers on simulant Defense Waste Processing Facility (DWPF) melter feeds. The task is to determine, based on the impact of the rheology modifier, if there are rheology modifiers that could reduce the water content of the slurry going to the DWPF melter, hence increasing the melt rate by decreasing the water loading. The rheology modifier in essence would allow a higher solids content slurry to have the same type of rheology or pumpability of a lower solids slurry. The modifiers selected in this report were determined based …

The Department of Energy (DOE) Complex has over two-hundred underground storage tanks containing over 80-million gallons of legacy waste from the production of nuclear weapons. The majority of the waste is located at four major sites across the nation and is planned for treatment over a period of almost forty years. The DOE Office of Technology Innovation & Development within the Office of Environmental Management (DOE-EM) sponsors technology research and development programs to support processing advancements and technology maturation designed to improve the costs and schedule for disposal of the waste and closure of the tanks. Within the waste processing focus area are numerous technical initiatives which included the development of a suite of waste removal technologies to address the need for proven equipment and techniques to remove high level radioactive wastes from the waste tanks that are now over fifty years old. In an effort to enhance the efficiency of waste retrieval operations, the DOE-EM Office of Technology Innovation & Development funded an effort to improve communications and information sharing between the DOE's major waste tank locations as it relates to retrieval. The task, dubbed the Retrieval Knowledge Center (RKC) was co-lead by the Savannah River National Laboratory (SRNL) …

This presentation includes results of composite data products and a summary of the analysis objectives and data flow for the projects.

The DOE Office of Environmental Management (DOE-EM) Office of Engineering and Technology is responsible for implementing EM's International Cooperative Program. Over the past 15 years, collaborative work has been conducted through this program with researchers in Russia, Ukraine, France, United Kingdom and Republic of Korea. Currently, work is being conducted with researchers in Russia and Ukraine. Efforts aimed at evaluating and advancing technologies to support U.S. high-level waste (HLW) vitrification initiatives are being conducted in collaboration with Russian researchers. Work at Khlopin Radium Institute (KRI) is targeted at improving the throughput of current vitrification processes by increasing melting rate. These efforts are specifically targeted at challenging waste types identified at the Savannah River Site (SRS) and Hanford Site. The objectives of current efforts at SIA Radon are to gain insight into vitrification process limits for the cold crucible induction melter (CCIM) technology. Previous demonstration testing has shown that the CCIM offers the potential for dramatic increases in waste loading and waste throughput. However, little information is known regarding operational limits that could affect long-term, efficient CCIM operations. Collaborative work with the Russian Electrotechnical University (ETU) 'LETI' is aimed at advancing CCIM process monitoring, process control and design. The goal is …

Endo-xylanase (from Bacillus subtilis) or ferulic acid esterase (from Aspergillus niger) were expressed in wheat under the control of the endosperm specific 1DX5 glutenin promoter. Constructs both with and without the endoplasmic reticulum retention signal KDEL were used. Transgenic plants were recovered in all four cases but no qualitative differences could be observed whether KDEL was added or not. Endo-xylanase activity in transgenic grains was increased between two and three fold relative to wild type. The grains were shriveled and had a 25-33% decrease in mass. Extensive analysis of the cell walls showed a 10-15% increase in arabinose to xylose ratio, a 50% increase in the proportion of water extractable arabinoxylan, and a shift in the MW of the water extractable arabinoxylan from being mainly larger than 85 kD to being between 2 kD and 85 kD. Ferulic acid esterase expressing grains were also shriveled and the seed weight was decreased by 20-50%. No ferulic acid esterase activity could be detected in wild type grains whereas ferulic acid esterase activity was detected in transgenic lines. The grain cell walls had 15-40% increase in water unextractable arabinoxylan and a decrease in monomeric ferulic acid between 13 and 34%. In all the …

The National Museum of the Pacific War presents an interview with Thomas Stevenson. Stevenson joined the Navy around 1942. He completed Naval Communications training. Beginning mid-1944, he served aboard the USS Samuel B. Roberts (DE-413). He shares his experiences through the Battle of Samar, and the sinking of the Roberts in October. Stevenson was then assigned on staff to the Command Transport Division 107, working with converted destroyer escorts. He traveled to Midway, Guam, Okinawa and the Philippines. After the war ended, he assisted with transported troops for occupation forces in Japan. Stevenson returned to the US and received his discharge in late 1945.

The National Museum of the Pacific War presents an oral interview with James Comet. Comet, the son of a coal miner, left school in the eighth grade and entered the workforce after his father suffered a debilitating injury. When Comet initially volunteered for the Navy, he was refused because his family depended on him. In 1943, he successfully enlisted and was sent to gunnery school. Upon completion, he was assigned to USS Samuel B. Roberts (DE-413) as the pointer on a gun crew. Traveling through a typhoon en route to the Philippines, Comet scrambled to secure a loose gun on the deck. While on patrol duty, the ship engaged enemy vessels, and Comet fired upon their spotter planes. When the ship took multiple hits and was sunk at the Battle off Samar, Comet rescued an officer and abandoned ship. He played dead in the water, still under fire. Comet was rescued two days later and reassigned to the Puget Sound ammunition depot until his discharge in May 1946.

The National Museum of the Pacific War presents an oral interview with Robert Harden. Harden left school at 16 years old and joined the Navy in 1944. After basic training in Norfolk, he was assigned to USS Samuel B. Roberts (DE-413). Aboard ship, he was assigned to the first deck division. His battle station was at a five-inch gun, retrieving spent shells. He survived a typhoon en route to the Philippines, only to enter into combat at the Battle off Samar. Harden abandoned ship and climbed aboard a raft after throwing away his leaking lifebelt. Three enemy ships passed Harden before he was finally rescued. Harden finished the war in Seattle, painting ships and stacking ammunition until his discharge in late 1946.

The National Museum of the Pacific War presents an oral interview with Ernest Huffman. Huffman joined the Navy in January 1944 and received basic training in Bainbridge and gunnery training in Norfolk. Upon completion, he was assigned to the USS Samuel B. Roberts (DE-413) as a pointer on a five-inch gun mount. He was then transferred to the bridge as a talker, relaying information from the CIC to the gunnery officer. While on the midnight watch, he was among the first to become aware of the Japanese fleet’s presence in the Surigao Strait. The Samuel B. Roberts put out a smoke screen and waited to fire until they were within striking distance of the enemy fleet. As the Battle off Samar began, the skipper dodged shells until the enemy zeroed in. The Samuel B. Roberts took several hits, while the nearby USS Gambier Bay (CVE-73) was dramatically aflame. The crew abandoned ship and watched the Samuel B. Roberts sink. Huffman was rescued 52 hours later and returned home safely. He was discharged in May 1946.
