The development and employment of a new diagnostic instrument for characterizing intense, heavy ion beams is reported on. This instrument, the ''Gated Beam Imager'' or ''GBI'' was designed for use on Lawrence Livermore National Laboratory Heavy Ion Fusion Project's ''Small Recirculator'', an integrated, scaled physics experiment and engineering development project for studying the transport and control of intense heavy ion beams as inertial fusion drivers in the production of electric power. The GBI allows rapid measurement and calculation of a heavy ion beam's characteristics to include all the first and second moments of the transverse phase space distribution, transverse emittance, envelope parameters and beam centroid. The GBI, with appropriate gating produces a time history of the beam resulting in a 4-D phase-space and time ''map'' of the beam. A unique capability of the GBI over existing diagnostic instruments is its ability to measure the ''cross'' moments between the two transverse orthogonal directions. Non-zero ''cross'' moments in the alternating gradient lattice of the Small Recirculator are indicative of focusing element rotational misalignments contributing to beam emittance growth. This emittance growth, while having the same effect on the ability to focus a beam as emittance growth caused by non-linear effects, is in …

The Thomas Jefferson National Accelerator Facility (Jefferson Lab) has developed a set of Work Smart Standards for the Lab. The effort incorporated the Lab`s performance-based contract into the Necessary and Sufficient (N and S) Standards identification process of the DOE. A rigorous protocol identified hazards in the workplace and standards that provide adequate protection of workers, public, and the environment at reasonable cost. The intensive process was a joint effort between the Lab and DOE and it required trained teams of knowledgeable experts in three fields: (1) actual required work conditions at Jefferson Lab; (2) laws, regulations, DOE directives and performance-based contracts; and (3) Environmental Health and Safety (EH and S), Rad Con, and QA. The criteria for selection of the teams, the database designed and used for the process, and lessons learned are discussed.

Lanczos algorithm is a very effective method for finding extreme eigenvalues of symmetric matrices. It requires less arithmetic operations than similar algorithms, such as, the Arnoldi method. In this paper, the authors present their parallel version of the Lanczos method for symmetric generalized eigenvalue problem, PLANSO. PLANSO is based on a sequential package called LANSO which implements the Lanczos algorithm with partial re-orthogonalization. It is portable to all parallel machines that support MPI and easy to interface with most parallel computing packages. Through numerical experiments, they demonstrate that it achieves similar parallel efficiency as PARPACK, but uses considerably less time.

In May of 1996, the US Department of Energy implemented a four-year demonstration project identified as the Hanford Tanks Initiative (HTI). The HTI mission is to minimize technical uncertainties and programmatic risks by conducting demonstrations to characterize and remove tank waste using technologies and methods that will be needed in the future to carry out tank waste remediation and tank farm closure at the Hanford Site. Included in the HTI scope is the development of retrieval performance evaluation criteria supporting readiness to close single-shell tanks in the future. A path forward that includes evaluation of closure basis alternatives has been outlined to support the development of retrieval performance evaluation criteria for the AX Farm, and eventual preparation of the SEIS for AX Farm closure. This report documents the results of the Task 4, Waste Inventory study performed to establish the best-basis inventory of waste contaminants for the AX Farm, provides a means of estimating future soil inventories, and provides data for estimating the nature and extent of contamination (radionuclide and chemical) resulting from residual tank waste subsequent to retrieval. Included in the report are a best-basis estimate of the existing radionuclide and chemical inventory in the AX Farm Tanks, an …

This document defines the performance requirements for a graphic display dispatching system to support Hanford Patrol Operations Center. This document reflects the as-built requirements for the system that was delivered by GTE Northwest, Inc. This system provided a commercial off-the-shelf computer-aided dispatching system and alarm monitoring system currently in operations at the Hanford Patrol Operations Center, Building 2721E. This system also provides alarm back-up capability for the Plutonium Finishing Plant (PFP).

During this reporting period the authors continued their investigations of how low rank coals are degraded by wood rotting fungi. Previous investigations showed that ligninolytic cultures of P. chrysosporium could decolorize soluble low rank coal macromolecule. The authors continue to investigate this phenomenon. Consistent with earlier observations they conclude that soluble coal macromolecule is decolorized in ligninolytic cultures of P. chrysosporium. To determine if this fungus can depolymerize coal macromolecule, samples were analyzed by GPC-HPLC. These analyses suggested that when coal macromolecules were incubated with ligninolytic cultures of P. chrysosporium a slight decrease in the average peak molecular weight of this mixture had occurred. During this reporting period they also discovered that changes in buffer composition can alter the peak retention times of coal macromolecules during GPC-HPLC probably by causing dissociation and reassociation of individual macromolecules. In other experiments it has been shown that lignin peroxidases that are secreted by ligninolytic cultures of P. chrysosporium are responsible, at least in part, for decolorization of coal macromolecules. Taken together, these studies show that the lignin degrading system of P. chrysosporium is able to enzymatically attack macromolecules solubilized from low rank coal. The ability of nonacclimated bacteria from sewage sludge to used …

A facility effluent monitoring plan is required by the US Department of Energy in DOE Order 5400.1 for any operations that involve hazardous materials and radioactive substances that could impact employee or public safety or the environment. This document is prepared using the specific guidelines identified in A Guide for Preparing Hanford Site Facility Effluent Monitoring Plans, WHC-EP-0438-01. This facility effluent monitoring plan assesses effluent monitoring systems and evaluates whether these systems are adequate to ensure the public health and safety as specified in applicable federal, state, and local requirements. This facility effluent monitoring plan will ensure long-range integrity of the effluent monitoring systems by requiring an update whenever a new process or operation introduces new hazardous materials or significant radioactive materials. This document must be reviewed annually even if there are no operational changes, and it must be updated, at a minimum, every 3 years.

During the past quarter, protocols for pyrolysis and combustion experiments were developed. The performance of the new control algorithms was evaluated, particularly for the rapid pyrolysis experiments where heating rates ranging from 100 to 1,000 C/s were achieved. Finally, a new digital image analysis procedure was developed to detect and quantify thermal ignitions of burning coal or char particles.

This document describes the original basis for selection of the analog input setpoints for the MICON Automation System. In most cases the setpoints were based on vendor supplied information and design requirements. However, some setpoints were also established based on engineering judgment. These setpoints are subject to change as more experience with operation of the ventilation system is obtained. Revision 1 incorporates minor changes to ensure the document setpoints accurately reflect limits established in OSD-T-151-00019, Rev B-0.

This document is the final report for tank 241-AP-107 grab samples. Three grab samples were collected from riser 1 on September 11, 1997. Analyses were performed on samples 7AP-97-1, 7AP-97-2 and 7AP-97-3 in accordance with the Compatibility Grab Sampling and Analysis Plan (TSAP) (Sasaki, 1997) and the Data Quality Objectives for Tank Farms Waste Compatibility Program (DQO) (Rev. 1: Fowler, 1995; Rev. 2: Mulkey and Nuier, 1997). The analytical results are presented in the data summary report (Table 1). A notification was made to East Tank Farms Operations concerning low hydroxide in the tank and a hydroxide (caustic) demand analysis was requested. The request for sample analysis (RSA) (Attachment 2) received for AP-107 indicated that the samples were polychlorinated biphenyl (PCB) suspects. Therefore, prior to performing the requested analyses, aliquots were made to perform PCB analysis in accordance with the 222-S Laboratory administrative procedure, LAP-101-100. The results of this analysis indicated that no PCBs were present at 50 ppm and analysis proceeded as non-PCB samples. The results and raw data for the PCB analysis will be included in a revision to this document. The sample breakdown diagrams (Attachment 1) are provided as a cross-reference for relating the tank farm customer …
