In this report, we summarize our current collobarative efforts, involving three national laboratories: Idaho National Laboratory (INL), Pacific Northwest National Laboratory (PNNL) and Los Alamos National Laboatory (LANL), to develop a computational framework for homogenous and heterogenous nucleation mechanisms into the generic phase-field model. During the studies, the Fe-Cr system was chosen as a model system due to its simplicity and availability of reliable thermodynamic and kinetic data, as well as the range of applications of low-chromium ferritic steels in nuclear reactors. For homogenous nucleation, the relavant parameters determined from atomistic studies were used directly to determine the energy functional and parameters in the phase-field model. Interfacial energy, critical nucleus size, nucleation rate, and coarsening kinetics were systematically examined in two- and three- dimensional models. For the heteregoneous nucleation mechanism, we studied the nucleation and growth behavior of chromium precipitates due to the presence of dislocations. The results demonstrate that both nucleation schemes can be introduced to a phase-field modeling algorithm with the desired accuracy and computational efficiency.

A fusion pilot plant study was initiated to clarify the development needs in moving from ITER to a first of a kind fusion power plant. The mission of the pilot plant was set to encompass component test and fusion nuclear science missions yet produce net electricity with high availability in a device designed to be prototypical of the commercial device. The objective of the study was to evaluate three different magnetic configuration options, the advanced tokamak (AT), spherical tokamak (ST) and compact stellarator (CS) in an effort to establish component characteristics, maintenance features and the general arrangement of each candidate device. With the move to look beyond ITER the fusion community is now beginning to embark on DEMO reactor studies with an emphasis on defining configuration arrangements that can meet a high availability goal. This paper reviews the AT pilot plant design, detailing the selected maintenance approach, the device arrangement and sizing of the in-vessel components. Details of interfacing auxiliary systems and services that impact the ability to achieve high availability operations will also be discussed.

Toroidal precession is commonly understood as the orbit-averaged toroidal drift of guiding centers in axisymmetric and quasisymmetric configurations. We give a new, more natural description of precession as a geometric phase effect. In particular, we show that the precession angle arises as the holonomy of a guiding center's poloidal trajectory relative to a principal connection. The fact that this description is physically appropriate is borne out with new, manifestly coordinate-independent expressions for the precession angle that apply to all types of orbits in tokamaks and quasisymmetric stellarators alike. We then describe how these expressions may be fruitfully employed in numerical calculations of precession.

The objective of Solids Accumulation activities was to perform scaled testing to understand the behavior of remaining solids in a Double Shell Tank (DST), specifically AW-105, at Hanford during multiple fill, mix, and transfer operations. It is important to know if fissionable materials can concentrate when waste is transferred from staging tanks prior to feeding waste treatment plants. Specifically, there is a concern that large, dense particles containing plutonium could accumulate in poorly mixed regions of a blend tank heel for tanks that employ mixing jet pumps. At the request of the DOE Hanford Tank Operations Contractor, Washington River Protection Solutions, the Engineering Development Laboratory of the Savannah River National Laboratory performed a scouting study in a 1/22-scale model of a waste staging tank to investigate this concern and to develop measurement techniques that could be applied in a more extensive study at a larger scale. Simulated waste tank solids: Gibbsite, Zirconia, Sand, and Stainless Steel, with stainless steel particles representing the heavier particles, e.g., plutonium, and supernatant were charged to the test tank and rotating liquid jets were used to mix most of the solids while the simulant was pumped out. Subsequently, the volume and shape of the mounds …

This report gives a brief overview of P.L. 110-49, the Foreign Investment and National Security Act of 2007. Although both the President and Congress are directly involved in formulating the scope and direction of U.S. foreign investment policy, this law broadens Congress' oversight role; it also explicitly includes the areas of homeland security and critical infrastructure as separately-identifiable components of national security that the President must consider when evaluating the national security implications of a foreign investment transaction.

The project involves drilling deeper in the Camp Aqua well dri lled in June 1982 as part of an effort to develop an ethanol plant. The purpose of the current drill ing effort is to determine if water at or above 165°F exists for the use in low temperature resource power generation. Previous geothermal resource study efforts in and around Hot Springs , MT and the Camp Aqua area (NE of Hot Springs) have been conducted through the years. A confined gravel aquifer exists in deep alluvium overlain by approximately 250’ of si lt and c lay deposits from Glacial Lake Missoula. This gravel aquifer overlies a deeper bedrock aquifer. In the Camp Aqua area several wel l s exist in the gravel aquifer which receives hot water f rom bedrock fractures beneath the area. Prior to this exploration, one known well in the Camp Aqua area penetrated into the bedrock without success in intersecting fractures transporting hot geothermal water. The exploration associated with this project adds to the physical knowledge database of the Camp Aqua area. The dri l l ing effort provides additional subsurface information that can be used to gain a better understanding of the bedrock formation …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) assessment of potential governance options for its Military Health System (MHS) did not provide complete information on the options' total cost impact and their strengths and weaknesses. As part of DOD's assessment, it identified 13 potential governance options for the MHS and included a limited analysis of the options' estimated costs savings and their strengths and weaknesses. All of the options would create a shared services concept to consolidate common services, such as medical logistics, acquisition, and facility planning, under the control of a single entity. DOD selected an option that would create a defense health agency to, among other things, assume the responsibility for creating and managing shared services, and leave the longstanding military chain of command intact with the services in control of the military hospitals. The National Defense Authorization Act (Act) for Fiscal Year 2012 required DOD to submit a report to congressional committees that would, among other things, estimate the cost savings and analyze the strengths and weaknesses of each option. Using key principles derived from federal guidance, including cost estimating and economic analysis documents, GAO determined …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Labor (Labor) facilitates states’ efforts to modernize information technology (IT) systems supporting their unemployment insurance (UI) programs by (1) providing funds for administrating overall UI operations and (2) participating in groups that provide technical support to states. While the federal-state structure of the UI program places primary responsibility for its administration on the states, Labor provides potential strategies for IT modernization activities through supplemental budget funds."

A letter report issued by the Government Accountability Office with an abstract that begins "Approximately two-thirds of the Department of Homeland Security’s (DHS) major information technology (IT) investments are meeting their cost and schedule commitments (i.e., goals). Specifically, out of 68 major IT investments in development, 47 were meeting cost and schedule commitments. The remaining 21—which total about $1 billion in spending—had one or more subsidiary projects that were not meeting cost and/or schedule commitments (i.e., they exceeded their goals by at least 10 percent, which is the level at which the Office of Management and Budget (OMB) considers projects to be at increased risk of not being able to deliver planned capabilities on time and within budget.)"

A letter report issued by the Government Accountability Office with an abstract that begins "Among the 27 agencies that GAO studied, all have fully or partially defined goals or purposes for their architectures, 11 have fully or partially established a method or metrics for measuring outcomes resulting from the use of their architectures, while 5 have fully or partially measured and reported outcomes and benefits."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Commerce's Economic Development Administration (EDA) used its standard grant award process to announce, receive, and review applications for the Community Trade Adjustment Assistance (CTAA) program, with modifications related to program eligibility. To comply with legislative requirements, EDA reached out to eligible communities by identifying those with workers or firms already certified as trade impacted by other trade adjustment assistance programs. EDA awarded the grants in accordance with the review and selection process outlined in the CTAA federal funding opportunity--the program's grant application announcement. More than half of the grants were for construction projects, such as building roads and installing broadband fiber for industrial parks. Although EDA was able to adapt standard procedures already in place for its other grant programs, EDA officials cited some CTAA-specific challenges: first, the effort required to set up the new program for CTAA grants; second, a relatively limited time for the outreach and application process; and third, the development of a list of eligible communities for outreach, which proved to be a complex undertaking."

The Hanford Tank Waste Treatment and Immobilization Plant (WTP) is being constructed to treat the 56 million gallons of radioactive waste stored in 177 underground tanks at the Hanford Site. The WTP includes a pretreatment facility to separate the wastes into high-level waste (HLW) and low-activity waste (LAW) fractions for vitrification and disposal. The LAW will be converted to glass for final disposal at the Integrated Disposal Facility (IDF). Cast Stone – a cementitious waste form, has been selected for solidification of this secondary waste stream after treatment in the ETF. The secondary-waste Cast Stone waste form must be acceptable for disposal in the IDF. This secondary waste Cast Stone waste form qualification testing plan outlines the testing of the waste form and immobilization process to demonstrate that the Cast Stone waste form can comply with the disposal requirements. Specifications for the secondary-waste Cast Stone waste form have not been established. For this testing plan, Cast Stone specifications are derived from specifications for the immobilized LAW glass in the WTP contract, the waste acceptance criteria for the IDF, and the waste acceptance criteria in the IDF Permit issued by the State of Washington. This testing plan outlines the testing needed …
