Verification survey of the hot cell facility site, General Atomics, San Diego, California (open access)

Verification survey of the hot cell facility site, General Atomics, San Diego, California

From 1958, General Atomics maintain a hot cell facility in support of government-funded research into reactor fuels. As the use of the facility declined, General Atomics entered into an agreement with DOE to dismantle the facility and decontaminate and decommission (D&D) the site so that it could made available for unrestricted use. The Environmental Survey and Site Assessment Program (ESSAP) was requested to verify the final radiological status of the D&D effort. This is the report of ESSAP survey and verification activities conducted at the San Diego site from November 1999 through March 2000.

Analysis, tuning and comparison of two general sparse solvers for distributed memory computers (open access)

Analysis, tuning and comparison of two general sparse solvers for distributed memory computers

We describe the work performed in the context of a Franco-Berkeley funded project between NERSC-LBNL located in Berkeley (USA) and CERFACS-ENSEEIHT located in Toulouse (France). We discuss both the tuning and performance analysis of two distributed memory sparse solvers (superlu from Berkeley and mumps from Toulouse) on the 512 processor Cray T3E from NERSC (Lawrence Berkeley National Laboratory). This project gave us the opportunity to improve the algorithms and add new features to the codes. We then quite extensively analyze and compare the two approaches on a set of large problems from real applications. We further explain the main differences in the behavior of the approaches on artificial regular grid problems. As a conclusion to this activity report, we mention a set of parallel sparse solvers on which this type of study should be extended.

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES (open access)

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. During this time period substantial progress has been made in developing low temperature deposition techniques to produce dense, nanocrystalline yttrium-stabilized zirconia films on both dense oxide and polymer substrates. Microstructural changes in unsupported nanocrystalline yttrium stabilized zirconia (ZrO{sub 2}:16%Y, or YSZ) thin films were examined as a function of temperature and annealing time in order to determine the grain growth exponent and the mechanisms of pinhole formation. Grain growth and pinhole formation were measured using high resolution transmission electron microscopy (HRTEM), normal imaging mode transmission electron microscopy (TEM), electron diffraction, and energy dispersive X-ray microanalysis (EDS). Grain growth was found to vary with a time exponent of about one half before pinhole formation and about one third after. Pinhole formation in 70 nm thick films occurred at temperatures near 600 C, corresponding to a grain size of about 15 nm, or a grain size to film thickness ration of approximately 0.25. The deposition of films on porous substrates is hampered by the penetration of the polymer precursor solution into the substrate whose pores as > 0.2 …

The Case for a 500 GEV E+E - Linear Collider (open access)

The Case for a 500 GEV E+E - Linear Collider

There are now several proposals that have been put forward from around the world for an e{sup +}e{sup {minus}} linear collider with an initial center of mass energy of 500 GeV. In this paper, the authors discuss why a project of this type deserves priority as the next, major initiative in high energy physics.
