Environmental impact report addendum for the continued operation of Lawrence Livermore National Laboratory

Description: An environmental impact statement/environmental impact report (ES/EIR) for the continued operation and management of Lawrence Livermore National Laboratory (LLNL) was prepared jointly by the U.S. Department of Energy (DOE) and the University of California (UC). The scope of the document included near-term (within 5-10 years) proposed projects. The UC Board of Regents, as state lead agency under the California Environmental Quality Act (CEQA), certified and adopted the EIR by issuing a Notice of Determination on November 20, 1992. The DOE, as the lead federal agency under the National Environmental Policy Act (NEPA), adopted a Record of Decision for the ES on January 27, 1993 (58 Federal Register [FR] 6268). The DOE proposed action was to continue operation of the facility, including near-term proposed projects. The specific project evaluated by UC was extension of the contract between UC and DOE for UC`s continued operation and management of LLNL (both sites) from October 1, 1992, through September 30, 1997. The 1992 ES/EIR analyzed impacts through the year 2002. The 1992 ES/EIR comprehensively evaluated the potential environmental impacts of operation and management of LLNL within the near-term future. Activities evaluated included programmatic enhancements and modifications of facilities and programs at the LLNL Livermore site and at LLNL`s Experimental Test Site (Site 300) in support of research and development missions 2048 established for LLNL by Congress and the President. The evaluation also considered the impacts of infrastructure and building maintenance, minor modifications to buildings, general landscaping, road maintenance, and similar routine support activities.

Effective cleanup at LLNL: innovative technologies and approaches

Description: At the Lawrence Livermore National Laboratory (LLNL) Livermore Site Superfund Site, ground water restoration efforts have been ongoing since 1989. Based on plans committed to by DOE in the Record of Decision (ROD) for the Site in 1992, ground water cleanup was predicted to take 61 years. What began as conventional pump and treat has evolved into an effective Engineered Plume Collapse strategy that employs a well-stocked tool box of remediation technologies, processes, and methodologies. This �tool box� approach has proven effective in solving the vexing problem of restoring the chlorinated volatile organic compound (CVOC) contaminated aquifers beneath the site. The Engineered Plume Collapse strategy has been used to hydraulically control the plumes on the western and southern boundaries of the site, doubled the pounds of CVOC removed from the subsurface compared to predictions in the ROD plans, and �collapsed� offsite plumes. The three major components of the Engineered Plume Collapse strategy are: (1) collection and use of historical and current chemical and hydrogeologic data to accurately identify areas of contamination in the subsurface and guide decisions about on-going remediation needs, (2) design, construction and operation of small, portable, and inexpensive ground water treatment units to implement pump and treat and collapse contaminant plumes back to their source areas, and (3) effective use of more energetic contaminant mass removal technologies in source areas, such as chemical oxidation, reductive dehalogenation, steam stripping, and electro-osmosis.

INSPECTION SHOP: PLAN TO PROVIDE UNCERTAINTY ANALYSIS WITH MEASUREMENTS

Description: The LLNL inspection shop is chartered to make dimensional measurements of components for critical programmatic experiments. These measurements ensure that components are within tolerance and provide geometric details that can be used to further refine simulations. For these measurements to be useful, they must be significantly more accurate than the tolerances that are being checked. For example, if a part has a specified dimension of 100 millimeters and a tolerance of 1 millimeter, then the precision and/or accuracy of the measurement should be less than 1 millimeter. Using the ''10-to-1 gaugemaker's rule of thumb'', the desired precision of the measurement should be less than 100 micrometers. Currently, the process for associating measurement uncertainty with data is not standardized, nor is the uncertainty based on a thorough uncertainty analysis. The goal of this project is to begin providing measurement uncertainty statements with critical measurements performed in the inspection shop. To accomplish this task, comprehensive knowledge about the underlying sources of uncertainty for measurement instruments need to be understood and quantified. Moreover, measurements of elemental uncertainties for each physical source need to be combined in a meaningful way to obtain an overall measurement uncertainty.

Atmospheric release advisory capability: year 2000 documentation

Description: This checklist provides the minimum requirements to be met for the IV and V of Y2K compliance for each mission-critical system. However, please note that other important items specific to your Program, Field or Site Offices, or Laboratory may not be adequately addressed by this checklist. Consequently, it is the responsibility of each Local Y2K Project Coordinator to ensure that due diligence has been conducted, whereby every reasonable effort has been made to assure Y2K compliance, and these efforts have been documented. Additional requirements should be jointly reviewed and agreed to by the System Owner and the IV and V agent prior to its execution. The IV and V agent should undertake the activities necessary to address all items as thoroughly as possible. The System Owner should identify and be ready to provide access to any documents that will help in the IV and V process, such as requirement definition documents, test plans, test results, etc.

Damage Detection and Identification of Finite Element Models Using State-Space Based Signal Processing a Summation of Work Completed at the Lawrence Livermore National Laboratory February 1999 to April 2000

Description: Until recently, attempts to update Finite Element Models (FEM) of large structures based upon recording structural motions were mostly ad hoc, requiring a large amount of engineering experience and skill. Studies have been undertaken at LLNL to use state-space based signal processing techniques to locate the existence and type of model mismatches common in FEM. Two different methods (Gauss-Newton gradient search and extended Kalman filter) have been explored, and the progress made in each type of algorithm as well as the results from several simulated and one actual building model will be discussed. The algorithms will be examined in detail, and the computer programs written to implement the algorithms will be documented.

Process diagnostics for precision grinding brittle materials in a production environment

Description: Precision grinding processes are steadily migrating from research laboratory environments into manufacturing production lines as precision machines and processes become increasingly more commonplace throughout industry. Low-roughness, low-damage precision grinding is gaining widespread commercial acceptance for a host of brittle materials including advanced structural ceramics. The development of these processes is often problematic and requires diagnostic information and analysis to harden the processes for manufacturing. This paper presents a series of practical precision grinding tests developed and practiced at Lawrence Livermore National Laboratory that yield important information to help move a new process idea into production.

Experimentally Determined Coordinates for Three MILS Hydrophones Near Ascension Island

Description: We conducted an airgun survey in the waters of Ascension Island in May 1999 to determine new locations and depths for three Missile Impact Location System (MILS) hydrophones (ASC23, ASC24, and ASC26) currently in use by the Prototype International Data Center (PIDC) and the National Data Center (NDC). The nominal and new locations are summarized in Table 1. Although not rigorous, errors in the new locations and depths are conservatively estimated to be less than 100 m. The hydrophones are either on or near the ocean bottom in all three cases. The new depths are consistent with the following: Direct-phase airgun arrivals; Bathymetry determined along the track of the ship used for this airgun survey; Reflected phases from the airgun data; and Depths given in the original hydrophone installation report.

Studies of non-proportionality in alkali halide and strontium iodide scintillators using SLYNCI

Description: Recently a collaboration of LLNL and LBNL has constructed a second generation Compton coincidence instrument to study the non-proportionality of scintillators. This device, known as SLYNCI (Scintillator Light-Yield Non-proportionality Characterization Instrument), has can completely characterize a sample with less than 24 hours of running time. Thus, SLYNCI enables a number of systematic studies of scintillators since many samples can be processed in a reasonable length of time. These studies include differences in nonproportionality between different types of scintillators, different members of the same family of scintillators, and impact of different doping levels. The results of such recent studies are presented here, including a study of various alkali halides, and the impact of europium doping level in strontium iodide. Directions of future work area also discussed.

FY11 Level-2 Milestone 3953: TLCC2 contract awarded

Description: This report documents completion of FY11 L2 milestone No.3953-TLCC2 contract award. This milestone was scheduled for completion on 3/31/11 and was completed on 4/14/11. There is a separate milestone (3856), due at the end of the fiscal year, concerned with installation of the first LLNL SU and early user access. Efforts related to this tri-lab L2 milestone started early in 2010 with the development of tri-lab requirements for the second ASC capacity system procurement. The SOW was then developed along with necessary RFP paperwork and sent to HQ/DOE for their review prior to being released. There was significant delay in getting this step completed which led to this milestone being put at risk for several months. However, once the RFP was approved and released we were able to get the procurement back on track with aggressive proposal response and review timelines.
