Chemical Facility Security
Facilities handling large amounts of potentially hazardous chemical (i.e., chemical facilities) might be of interest to terrorists, either as targets for direct attacks meant to release chemicals into the community or as a source of chemicals for use elsewhere. For any individual facility, the risk is very small, but the risks may be increasing -- with potentially severe consequences for human health and the environment. Congress might choose to rely on existing efforts in the public and private sectors to improve chemical site security over time. Alternatively, Congress could expand existing environmental planning requirements for chemical facilities to require consideration of terrorism. Congress might also enact legislation to reduce risks, either by "hardening" defenses against terrorists or by requiring industries to consider use of safer chemicals, procedures, or processes.

China's Economic Conditions
China’s economy continues to be a concern to U.S. policymakers. On the one hand, China’s economic growth presents huge opportunities for U.S. exporters. On the other hand, the surge in Chinese exports to the United States has put competitive pressures on many U.S. industries. Many U.S. policymakers have argued that greater efforts should be made to pressure China to fully implement its WTO commitments and to change various economic policies deemed harmful to U.S. economic interests, such as its currency peg and its use of subsidies to support its SOEs. In addition, recent bids by Chinese state-owned firms to purchase various U.S. firms have raised concerns among Members over the impact such acquisitions could have on U.S. national and economic security.

Design and Evaluation of Ionic Liquids as Novel CO2 Absorbents
Progress from the fourth quarter 2005 activity on the project ''Design and Evaluation of Ionic Liquids as Novel CO{sub 2} Absorbents'' is provided. Major activities in three areas are reported: compound synthesis, property measurement and molecular modeling. Last quarter we reported the first ever experimental measurement of SO{sub 2} solubility in an ionic liquid. We showed that SO{sub 2} was very soluble in the ionic liquid 1-hexyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([hmim][Tf{sub 2}N]). This quarter, we have measured SO{sub 2} solubility in two more ionic liquids: 1-hexyl-3-methylpyridinium bis(trifluoromethanesulfonyl)imide ([hmpy][Tf{sub 2}N]) and 1-hexyl-3-methylimidazolium lactate ([hmim][lactate]). As with [hmim][Tf{sub 2}N], we find very high solubility of SO{sub 2} in these ionic liquids, but the lactate compounds shows the highest affinity for SO{sub 2} at low pressure. CO{sub 2} solubility was measured in three new compounds: [boronium][Tf{sub 2}N], 1-hexyl-3-methylimidazolium acesulfumate ([hmim][ace]), and 1-hexyl-3-methylimidazolium saccharinate ([hmim][sac]). We find relatively poor solubility of CO{sub 2} in the latter two compounds, and solubility comparable to [hmim][Tf{sub 2}N] in the boronium compound. We also synthesized four new ionic liquids this quarter and continued refinement of our molecular simulation technique for measuring gas solubility.

Development of a Manufacturing Process for High-Precision Cu EOS Targets
This document describes the development of a manufacturing process and the production of Cu EOS targets. The development of a manufacturing process for these targets required a great deal of research, because the specifications for the targets required a level of precision an order of magnitude beyond Target Fabrication's capabilities at the time. Strict limitations on the dimensions of the components and the interfaces between them required research efforts to develop bonding and deposition processes consistent with a manufacturing plan with a dimensional precision on the order of 0.1 {micro}m. Several months into this effort, the specifications for the targets were relaxed slightly as a result of discussions between the Target Fabrication Group and the physicists. The level of precision required for these targets remained an order of magnitude beyond previous capabilities, but the changes made it possible to manufacture targets to the specifications. The development efforts and manufacturing processes described in this document successfully produced a complete Cu EOS target that satisfied all of the fabrication and metrology specifications.

Education-Related Hurricane Relief: Legislative Action
This report provides an overview of the waivers that have been granted by the Department of Education in response to the Gulf Coast hurricanes; three public laws that have been enacted, specifically to provide financial relief to postsecondary students and institutions of higher education; and education-related hurricane relief provisions included in FY2006 defense appropriations. For K-12 education, the latter provides several waivers of existing requirements and appropriates $1.4 billion, primarily to restart school operations in affected areas and to provide emergency impact aid grants to schools serving displaced students. For higher education, P.L. 109-148 provides waivers of existing requirements and makes available $200 million to provide assistance under various HEA programs.

Emerging Prospects for Repository Success
Recent events are again raising some old issues and creating new opportunities regarding the future disposition of the used, or spent, fuel from nuclear power plants. Handling these challenges well will not only help set the stage for a robust nuclear energy future, but will reflect the growing linkages among nuclear power, nuclear waste management, international security, and public and political acceptance. The emerging global nuclear regime may make spent fuel management not only more important, but improve chances of success.

Evaluation of the DRAGON Code for VHTR Design Analysis.
This letter report summarizes three activities that were undertaken in FY 2005 to gather information on the DRAGON code and to perform limited evaluations of the code performance when used in the analysis of the Very High Temperature Reactor (VHTR) designs. These activities include: (1) Use of the code to model the fuel elements of the helium-cooled and liquid-salt-cooled VHTR designs. Results were compared to those from another deterministic lattice code (WIMS8) and a Monte Carlo code (MCNP). (2) The preliminary assessment of the nuclear data library currently used with the code and libraries that have been provided by the IAEA WIMS-D4 Library Update Project (WLUP). (3) DRAGON workshop held to discuss the code capabilities for modeling the VHTR.

Final Report for the Arroyo Las Positas Maintenance Impact Study, Lawrence Livermore National Laboratory
In 2000, the Lawrence Livermore National Laboratory's (LLNL) Environmental Protection Department, in coordination with Plant Engineering (PE), began dredging sections of the Arroyo Las Positas (ALP) to alleviate concerns about flooding of sensitive facilities within the mainsite of Lawrence Livermore National Laboratory. In order to reduce potential impacts on the federally threatened California red-legged frog (Rana aurora draytonii), LLNL proposed to dredge sections of the ALP in a ''checkerboard pattern'', resulting in a mosaic of open water habitat and vegetated sections (Figure 1). The Arroyo Las Positas Management Plan (Plan) was coordinated with both state and federal agencies including the U.S. Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDF&G), San Francisco Regional Water Quality Control Board (SFRWQCB), and the Army Corp of Engineers (ACOE). Water Discharge Requirements (WDRs) were issued for this project on December 30, 1999 (Order No. 99-086) by the SFRWQCB. Provision 19 of the WDRs outlined a five-year (2000 through 2004) Maintenance Impact Study (MIS) that LLNL began in coordination with dredging work that was conducted as part of the Arroyo Las Positas Management Plan. Provision 20 of these WDRs requires LLNL to submit a final report of the results of the Maintenance …

First Results from IceCube
IceCube is a 1 km{sup 3} neutrino observatory being built to study neutrino production in active galactic nuclei, gamma-ray bursts, supernova remnants, and a host of other astrophysical sources. High-energy neutrinos may signal the sources of ultra-high energy cosmic rays. IceCube will also study many particle-physics topics: searches for WIMP annihilation in the Earth or the Sun, and for signatures of supersymmetry in neutrino interactions, studies of neutrino properties, including searches for extra dimensions, and searches for exotica such as magnetic monopoles or Q-balls. IceCube will also study the cosmic-ray composition. In January, 2005, 60 digital optical modules (DOMs) were deployed in the South Polar ice at depths ranging from 1450 to 2450 meters, and 8 ice-tanks, each containing 2 DOMs were deployed as part of a surface air-shower array. All 76 DOMs are collecting high-quality data. After discussing the IceCube physics program and hardware, I will present some initial results with the first DOMs.
