Most Alfvenic activity in the frequency range between Toroidal Alfven Eigenmodes and roughly one half of the ion cyclotron frequency on NSTX [M. Ono, et al., Nucl. Fusion 40 (2000) 557], that is, approximately 0.3 MHz up to ≈ 1.2 MHz, are modes propagating counter to the neutral beam ions. These have been modeled as Compressional and Global Alfven Eigenmodes (CAE and GAE) and are excited through a Doppler-shifted cyclotron resonance with the beam ions. There is also a class of co-propagating modes at higher frequency than the counter-propagating CAE and GAE. These modes have been identified as CAE, and are seen mostly in the company of a low frequency, n=1 kink-like mode. In this paper we present measurements of the spectrum of these high frequency CAE (hfCAE), and their mode structure. We compare those measurements to a simple model of CAE and present evidence of a curious non-linear coupling of the hfCAE and the low frequency kink-like mode.

A letter report issued by the Government Accountability Office with an abstract that begins "Of the 71 nonmajor projects that the Department of Energy's (DOE) Office of Environmental Management (EM) and National Nuclear Security Administration (NNSA) completed or had under way from fiscal years 2008 to 2012, 21 met or are expected to meet their performance targets for scope, cost, and completion date. These projects included a $22 million EM project to expand an existing waste disposal facility at the Oak Ridge Reservation in Tennessee and a $199 million NNSA project to equip a radiological laboratory and office building at the Los Alamos National Laboratory in New Mexico. Another 23 projects did not meet or were not expected to meet one or more of their three performance targets for scope, cost, and completion date. Among these, 13 projects met or are expected to meet two targets, including a $548 million NNSA project to shut down a nuclear reactor in Russia for nonproliferation purposes; 8 projects met or are expected to meet one target; 1 project did not meet any of its targets; and 1 project was cancelled. Of the remaining 27 projects, many had insufficiently documented performance targets for scope, …

A letter report issued by the Government Accountability Office with an abstract that begins "Agency officials told us that enhanced use leases (EUL) help them utilize their underutilized property better; commonly cited benefits include enhanced mission activities, cash rent revenue, and value received through in-kind consideration. However, some agencies we reviewed do not include all costs associated with their EULs when they assess the performance of their EUL programs. Guidance from the Office of Management and Budget (OMB) does not specify what costs agencies should include in their EUL evaluations, resulting in variance among agencies. For example, the Department of Veterans Affairs (VA) and the Department of State do not consistently attribute EUL-related costs of consultant staff who administer the leases, and VA does not attribute various administrative costs that offset EUL benefits. Without fully accounting for all EUL costs, agencies may overstate the net benefits of their EUL programs."

The objective of this research program is to address major nuclear fuels performance issues for the design and use of oxide-type fuels in the current and advanced nuclear reactor applications. Fuel performance is a major issue for extending fuel burn-up which has the added advantage of reducing the used fuel waste stream. It will also be a significant issue with respect to developing advanced fuel cycle processes where it may be possible to incorporate minor actinides in various fuel forms so that they can be 'burned' rather than join the used fuel waste stream. The potential to fission or transmute minor actinides and certain long-lived fission product isotopes would transform the high level waste storage strategy by removing the need to consider fuel storage on the millennium time scale.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy (DOE) faces significant technical challenges in successfully constructing and operating the Waste Treatment and Immobilization Plant (WTP) project that is to treat millions of gallons of highly radioactive liquid waste resulting from the production of nuclear weapons. DOE and Bechtel National, Inc. identified hundreds of technical challenges that vary in significance and potential negative impact and have resolved many of them. Remaining challenges include (1) developing a viable technology to keep the waste mixed uniformly in WTP mix tanks to both avoid explosions and so that it can be properly prepared for further processing; (2) ensuring that the erosion and corrosion of components, such as tanks and piping systems, is effectively mitigated; (3) preventing the buildup of flammable hydrogen gas in tanks, vessels, and piping systems; and (4) understanding better the waste that will be processed at the WTP. Until these and other technical challenges are resolved, DOE will continue to be uncertain whether the WTP can be completed on schedule and whether it will operate safely and effectively."

This report provides basic information about U.S. and Russian nonstrategic nuclear weapons. It begins with a brief discussion of how these weapons have appeared in public debates in the past few decades, then summarizes the differences between strategic and nonstrategic nuclear weapons. It then provides some historical background, describing the numbers and types of nonstrategic nuclear weapons deployed by both nations during the Cold War and in the past decade; the policies that guided the deployment and prospective use of these weapons; and the measures that the two sides have taken to reduce and contain their forces. The report reviews the issues that have been raised with regard to U.S. and Russian nonstrategic nuclear weapons, and summarizes a number of policy options that might be explored by Congress, the United States, Russia, and other nations to address these issues.

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration (TSA) has inconsistently overseen and enforced its rail security incident reporting requirement because it does not have guidance and its oversight mechanisms are limited, leading to considerable variation in the types and number of incidents reported. Though some variation is expected in the number and type of incidents reported because of differences in rail agency size, location, and ridership, local TSA inspection officials have provided rail agencies with inconsistent interpretations of the reporting requirement. For example, local TSA officials instructed one rail agency to report all incidents related to individuals struck by trains. However, local TSA officials responsible for another rail agency said these incidents would not need to be reported as they are most often suicides with no nexus to terrorism. Providing guidance to local TSA inspection officials and rail agencies on the types of incidents that are to be reported could improve consistency across different TSA field offices. GAO also found inconsistency in TSA compliance inspections and enforcement actions because TSA has not utilized limited headquarters-level mechanisms as intended for ensuring consistency in these activities. TSA's rail security inspection policies …

Our goal was to study the flows within and above of a forested area and assess the degree to which horizontal subcanopy motions transport significant amounts of CO2. This process can explain why ecosystem respiration appears to be underestimated on calm nights. It is essential to understand the physical and biological mechanisms that determine relevant processes that occur on these ‘suspect’ nights.

A Saltstone waste form was prepared in the Savannah River National Laboratory (SRNL) from a Tank 50H sample and Z-Area premix material for the third quarter of calendar year 2012 (3QCY12). After a 34 day cure, samples of the saltstone were collected, and the waste form was shown to meet the South Carolina Hazardous Waste Management Regulations (SCHWMR) R.61-79.261.24 and R.61-79.268.48(a) requirements for a nonhazardous waste form with respect to RCRA metals and underlying hazardous constituents. These analyses met all quality assurance specifications of USEPA SW-846.

Tank 26F supernate sample was sent by Savannah River Remediation to Savannah River National Laboratory for evaporation test to help understand the underlying cause of the recent gravity drain line (GDL) pluggage during operation of the 2F Evaporator system. The supernate sample was characterized prior to the evaporation test. The evaporation test involved boiling the supernate in an open beaker until the density of the concentrate (evaporation product) was between 1.4 to 1.5 g/mL. It was followed by filtering and washing of the precipitated solids with deionized water. The concentrate supernate (or concentrate filtrate), the damp unwashed precipitated solids, and the wash filtrates were characterized. All the precipitated solids dissolved during water washing. A semi-quantitative X-ray diffraction (XRD) analysis on the unwashed precipitated solids revealed their composition. All the compounds with the exception of silica (silicon oxide) are known to be readily soluble in water. Hence, their dissolution during water washing is not unexpected. Even though silica is a sparingly water-soluble compound, its dissolution is also not surprising. This stems from its small fraction in the solids as a whole and also its relative freshness. Assuming similar supernate characteristics, flushing the GDL with water (preferably warm) should facilitate dissolution and …

US Army Corps of Engineers, Portland District (CENWP) operates the Bonneville Lock and Dam Project on the Columbia River. High spill flows that occurred during 2011 moved a large volume of rock from downstream of the spillway apron to the stilling basin and apron. Although 400 cubic yards of rocks were removed from the stilling basin, there are still large volumes of rock downstream of the apron that could, under certain flow conditions, move upstream into the stilling basin. CENWP is investigating operational changes that could be implemented to minimize future movement of rock into the stilling basin. A key analysis tool to develop these operational changes is a computational fluid dynamics (CFD) model of the spillway. A free-surface CFD model of the Bonneville spillway tailrace was developed and applied for four flow scenarios. These scenarios looked at the impact of flow volume and flow distribution on tailrace hydraulics. The simulation results showed that areas of upstream flow existed near the river bed downstream of the apron, on the apron, and within the stilling basin for all flows. For spill flows of 300 kcfs, the cross-stream and downstream extent of the recirculation zones along Cascade and Bradford Island was very …
