A preliminary error budget for the third harmonic converter for the National Ignition Facility (NIF) laser driver has been developed using a root-sum-square-accumulation of error sources. Such a budget sets an upper bound on the allowable magnitude of the various effects that reduce conversion efficiency. Development efforts on crystal mounting technology and crystal quality studies are discussed.

Glass has become a preferred waste form worldwide for radioactive wastes: however, there are limitations. Halogen-containing wastes can not be converted to glass because halogens form poor-quality waste glasses. Furthermore, halides in glass melters often form second phases that create operating problems. A new waste vitrification process, the Glass Material Oxidation and dissolution System (GMODS), removes these limitations by converting halogen-containing wastes into borosilicate glass and a secondary, clean, sodium-halide stream.

This document is the final laboratory report for B Plant Tk-21-1. A Resource Conservation and Recovery Act (RCRA) sample was taken from Tk-21 -1 September 26, 1996. This sample was received at 222-S Analytical Laboratory on September 27, 1996. Analyses were performed in accordance with the accompanying Request for Sample Analysis (RSA) and Letter of Instruction B PLANT RCRA SAMPLES TO 222S LABORATORY, LETTER OF INSTRUCTION (LOI) 2B-96-LOI-012-01 (LOI) (Westra, 1996). LOI was issued subsequent to RSA and replaces Letter of Instruction 2C-96-LOI-004-01 referenced in RSA.

This Safety Analysis Report for Packaging (SARP) Upgrade Plan reflects a SARP upgrade schedule based on the most current program needs. A performance agreement has been assigned, beginning in FY 1997, to update, revise, and/or cancel 20 percent of the existing onsite SARPS, so that 100 percent are reviewed and within current standards by the completion of the Project Hanford Management Contract (five-year period).

This paper presents the comparison of the COMOPS benchmark performance in MPI and shared memory on three different shared memory platforms: the DEC AlphaServer 8400/300, the SGI Power Challenge, and the HP-Convex Exemplar SPP1600. The paper also qualitatively analyzes the obtained performance data based on an understanding of the corresponding architecture and the MPI implementations. Some conclusions are made for the inter-processor communication performance on these three shared memory platforms.

Experiments and calculations indicate that the threshold pressure in spatial filters for distortion of a transmitted pulse scales approximately as I{sup O.2} and (F{number_sign}){sup 2} over the intensity range from 10{sup 14} to 2xlO{sup 15} W/CM{sup 2} . We also demonstrated an interferometric diagnostic that will be used to measure the scaling relationships governing pinhole closure in spatial filters.

The laser architecture of the NIF beamlines requires small-area beam dumps to safely absorb back reflections from the output and leakage through the PEPC switch. The problems presented by these beam dumps are that fluences they must absorb are very large, beyond the damage threshold of any material, and ablation of beam dump materials potentially contaminates adjacent optical components. Full scale tests have demonstrated that a stainless steel beam dump will survive fluence levels and energies as high as 820 j/CM{sup 2} and 2.5 kJ, respectively. Small scale tests with tungsten, tantalum, and stainless steel have demonstrated erosion rates less than about 0.5 {mu}m/shot, with stainless steel having the smallest rate. They also suggest that increased angles of incidence ({ge}60{degree}) will greatly reduce the material ablated directly back along the beam path.

This is the eighth in a series of quarterly reports describing the activities performed under Contract No. DE-AC21-94MC31160. Analyses of Hot Gas Stream Cleanup (HGCU) ashes and descriptions of filter performance address aspects of filter operation that are apparently linked to the characteristics of the collected ash or the performance of the ceramic barrier filter elements. Task 1 is designed to generate a data base of the key characteristics of ashes collected from operating advanced particle filters (APFS) and to relate these ash properties to the operation and performance of these filters. Task 2 concerns testing and failure analysis of ceramic filter elements. Under Task I during the past quarter, additional analyses were performed on ashes from the Ahlstrom 10 MWt Pressurized Fluidized Circulating Fluid Bed (PCFB) facility located at Karhula, Finland. Work continued on the HGCU data base being constructed in Microsoft Access. A variety of information has been entered into the data base, including numerical values, short or long text entries, and photographs. Detailed design of a bench top device for high temperature measurement of ash permeability has also begun. In addition to these activities, a paper was prepared and a poster was presented summarizing recent work performed …

This is the second page of a letter Rosenberg has sent to Berry in regards to Berry's participation in the Education Institute's National Conference, "Education For the Workplace Through the Arts." The Education Institute is inviting Berry to represent museum educators during a panel to comment on the DBAE program in general education and implementation. Cc'd on the letter is Val Marmillion, Lori Weisgerber, Jack Davis and Bill McCarter.

In regards to Berry's upcoming participation in attending the Education Institute's National Conference, "Education For the Workplace Through the Arts" from January 9th - 10th, 1997 and the DBAE, discipline-based art education, leadership forum that follows on January 11th. The DBAE forum will discuss the mobilization of DBAE to a national scale and elicit ideas about the best way to mobilize such practitioners.
