Geologic systems generally are complex with physical properties and trends that can be difficult to predict. Subsurface geology exerts a fundamental control on groundwater flow and contaminant transport. The primary source for direct observation of subsurface geologic information is a borehole. However, direct observations from a borehole essentially are limited to the diameter and spacing of boreholes and the quality of the information derived from the drilling. Because it is impractical to drill a borehole every few feet to obtain data, it is necessary to maximize the data gathered during limited drilling operations. A technically defensible balance between the customer`s data quality objectives and control of drilling costs through limited drilling can be achieved with proper conduct of operations. This report presents the minimum criteria for geologic and hydrologic characterization and sampling that must be met during drilling. It outlines the sampling goals that need to be addressed when drilling boreholes, and the types of drilling techniques that work best to achieve these goals under the geologic conditions found at Hanford. This report provides general guidelines for: (1) how sampling methods are controlled by data needs, (2) how minimum sampling requirements change as knowledge and needs change, and (3) when …

Depolymerization of coals at low temperatures may offer advantages over thermal bond cleavage. Because bond cleavage energies of radical cations are lower than the corresponding homolytic bond cleavage energies of the same bond, generation of radical cations in coal may make possible depolymerization at lower temperatures. We seek to investigate the above possibility using single molecules containing functional groups common in coals. Since the generation of a radical cation requires the removal of an electron from a neutral molecule, a primary focus of the study will be finding oxidants that will remove an electron from compounds with structural similarity to those typically found in coals. The study will also be concerned with the decomposition of radical cations and the products formed as a result of the decomposition. In our last report we described that treatment of bibenzyl and neo-pentylbenzene with Fe(III) (1,10-phenanthroline){sub 3}(ClO{sub 4}){sub 3} (Fe(III)(PHEN)) in refluxing CH{sub 3}CN (82{degrees}C) failed to produce substantial bond cleavage {beta} to the aromatic ring. Because bond cleavage was not observed, we have continued our study by moving to compounds which have lower ionization potentials as well as study other oxidants.

Under DOE sponsorship, as directed by the Los Alamos National Laboratory (LANL), the MACCS code (version 1.5.11.1) [Ch92] was modified to implement a series of improvements in its modeling of emergency response actions. The purpose of this effort has been to aid the Westinghouse Savannah River Company (WSRC) in its performance of the Level III analysis for the Savannah River Site (SRS) probabilistic risk analysis (PRA) of K Reactor [Wo90]. To ensure its usefulness to WSRC, and facilitate the new model`s eventual merger with other MACCS enhancements, close cooperation with WSRC and the MACCS development team at Sandia National Laboratories (SNL) was maintained throughout the project. These improvements are intended to allow a greater degree of flexibility in modeling the mitigative actions of evacuation and sheltering. The emergency response model in MACCS version 1.5.11.1 was developed to support NRC analyses of consequences from severe accidents at commercial nuclear power plants. The NRC code imposes unnecessary constraints on DOE safety analyses, particularly for consequences to onsite worker populations, and it has therefore been revamped. The changes to the code have been implemented in a manner that preserves previous modeling capabilities and therefore prior analyses can be repeated with the new code.

This Interface Control Document (ICD) describes the interface between the Tank Farm System and the Central Waste Complex (CWC) or the Low-Level Burial Ground (LLBG). The Tank Farm System generates solid waste during operations. These facilities do not have a direct physical interface since the waste will be moved by truck to the CWC or LLBG. The purpose of the ICD process is to formalize working agreements between the River Protection Project (RPP) Tank Farm System and organization/companies internal and external to RPP. This ICD has been developed as part of the requirements basis for design of the DST System to support the Phase I Privatization effort. The signatures on the cover page of this document indicate agreement between the parties that this document reflects the current technical baseline for each system and that the requirements contained in this document will not be revised without the agreement of all parties.

In environmental samples, the major analytical limitation on the use of uranium {sup 238}U/{sup 235}U determinations as an indicator of uranium enrichment is mass dependent bias occurring during the measurement. The double-spike technique can be used to correct the data for this effect. The purpose of this experiment was to evaluate the variation of mass bias among several laboratories and to determine the extent to which the double-spike could be used to reduce analytical uncertainty. Four laboratories performed replicate analyses on each of three samples. Generally mass bias was determined to be small compared to the random scatter of the measurements, but in at least one case, the bias was > 1%. In 8 of 12 cases, intra-laboratory variance was reduced when the double-spike correction was applied. For all three samples, the inter-laboratory variance was decreased, though the decrease was small. Based on a reasonable assumption about the true isotopic compositions of the samples, the accuracy of 11 of the twelve analyses was improved by applying the double spike correction. When the double spike is used to correct for mass bias, the {sup 238}U/{sup 235}U accuracy is better than 1% even for samples as small as 1 ng. For 50 …

During fiscal year 1999, the level of success achieved by the Tank Waste Remediation System (TWRS) shall be determined by specific performance measures. These measures take the form of significant deliverables, one of which is the completion of Tank Characterization Reports (TCRS). In order to achieve success regarding the TCR performance deliverable, multiple organizations across TWRS must work together. Therefore, the requirements and expectations needed from each of these TWRS organizations were examined in order to gain an understanding of the performance necessary from each organization to achieve the end deliverable. This memorandum of understanding (MOU) documents the results of this review and establishes the performance criteria by which TWRS will assess its progress and success. These criteria have been determined based upon a TWRS Characterization Project budget of $42.1 million for fiscal year 1999; if this budget is changed or the currently identified workscope is modified, this MOU will need to be revised accordingly. This MOU is subdivided into six sections, where sections three through six each identify individual interfaces between TWRS organizations. The specific performance criteria related to each TWRS organizational interface are then delineated in the section, along with any additional goals or issues pertaining to that …

Since the FMEF did not have a mission, a formal drawing verification program was not developed, however, a verification process on essential electrical single line drawings and panel schedules was established to benefit the operations lock and tag program and to enhance the electrical safety culture of the facility. The purpose of this document is to provide a basis by which future landlords and cognizant personnel can understand the degree of verification performed on the electrical single lines and panel schedules. It is the intent that this document be revised or replaced by a more formal requirements document if a mission is identified for the FMEF.

The Acceptance Test Procedure (ATP) Program for Project W-049H covers the following activities: Disposal system, Collection system, Instrumentation and control system. Each activity has its own ATP. The purpose of the ATPs is to verify that the systems have been constructed in accordance with the construction documents and to demonstrate that the systems function as required by the Project criteria. This ATP has been prepared to demonstrate that the Collection System Instrumentation functions as required by project criteria.

Bench scale experiments showed that the peak H2 generation rate increases with an increase in the PHA addition/evaporation rate. A 2,500 gal Slurry Mix Evaporator Condensate Tank (SMECT) was installed in the IDMS to allow performing PHA addition and evaporation both at the same rate and continuously. The SMECT allowed prototypic boil-up rates to be used, which allowed the investigation of hydrogen evolution in a more prototypic fashion and also made it possible to investigate solids entrainment. in the offgas. The results of these investigations are discussed in this report.

The FY95 Work Plan for TMACS and CASS Software Projects describes the activities planned for the current fiscal year. This plan replaces WHC-SD-WM-SDP-008. The TMACS project schedule is included in the TWRS Integrated Schedule.

The purpose of this Acceptance Test Procedure (ATP) for the Project W-049H, Treated Effluent Disposal Facility, is to verify that the collection system equipment installed as Pump Station No. 1 (225-W) and Pump Station No. 2 (225-E) have been installed in accordance with the design documents and function as required by the project criteria. This will be a wet test with potable water being introduced into the pump pits to test for leakage. Potable water will also be employed in the testing of the pumps and related mechanical equipment. All Instrument and Control equipment related to the pump stations will be checked electronically with simulated inputs/outputs when actual input/output signals are unavailable. Water from Pump Station 1 will be moved through the TEDF piping system and discharged into the disposal ponds. This will check the proper function of the air/vac valves not tested during construction, and the automated samplers.

Magnetic circular dichroism in x-ray absorption is used to investigate the in-plane, remnant magnetization of well-characterized Ni{sub 0.48}/Au{sub 0.52} multilayers. Large superlattice strains are found in this multilayer system for samples with a 2nm layer pair spacing. A larger dichroism is found in the Ni 2p absorption edge for a 1.8 nm than for a 4.4 nm layer pair sample. The larger dichroism is consistent with a larger magnitude of in-plane strain for the Ni layers and a larger total magnetic anisotropy energy as previously shown from magnetization curves.

Tanks that are known or suspected to retain and occasionally release flammable gases are equipped with Standard Hydrogen Monitoring System (SHMS) cabinets. These cabinets contain Whittaker{trademark} electrochemical cells and may also have a gas chromatograph (GC) and/or a Bruel and Kjaer infrared photo-acoustic multi-gas monitor (B&K). The GC and B&K will be referred to collectively as ''analytical instruments'' in this document. Using these instruments, a tank can be monitored for hydrogen, helium, ammonia, methane, and nitrous oxide. Air from the tank vent header (for actively ventilated tanks) or dome space (for passively ventilated tanks) is drawn continuously through the monitoring instruments via a sample pump. This monitoring is performed to track the gas release behavior of selected waste storage tanks and to help identify any potentially serious gas release behavior. Vapor grab samples may be obtained from the SHMS as well and analyzed with a mass spectrometer to obtain concentration data about hydrogen and other gases. This document describes the requirements for the operation, maintenance, calibration, and data collection for the Standard Hydrogen Monitoring System. Additionally, this document defines who is responsible for the various tasks.

MALDI MS was developed as a way of getting molecular weight information on small quantities (picomole to femtomole levels) of high-mass, thermally labile macromolecules. While most other analytical MS ionization techniques cause fragmentation, decomposition, or multiple charging, MALDI efficiently places intact macromolecules into the gas phase with little fragmentation or rearrangement. This project had 3 objectives: establish the MALDI capability at LLNL, perform fundamental studies of analyte-matrix interactions, and apply the technique for biochemical research. A retired time-of-flight instrument was adapted for MALDI analyses, relevant parameters influencing the MALDI process were identified for further study (matrix molar absorptivity, sample crystal preparation), and collaborations were established with research groups in the Biology and Biotechnology Research Program at LLNL. In MALDI, the macromolecule of interest is mixed with a high-molar excess (1:100 to 1:10,000) of an organic matrix which readily absorbs energy at the wavelength corresponding to a UV laser. Upon laser irradiation, the matrix absorbs the majority of the energy, causing it to desorb from the surface and gently release the macromolecule into the gas phase with little or no fragmentation. Once in the gas phase, ion-molecule reactions between excited matrix and neutral macromolecules generated ionized analyte species which then can …

This report presents the drop test results for the 9975 radioactive material shipping package being dropped 30 feet onto a unyielding surface followed by a 40-inch puncture pin drop. The purpose of these drops was to show that the package lid would remain attached to the drum. The 30-foot drop was designed to weaken the lid closure lug while still maintaining maximum extension of the lugs from the drum surface. This was accomplished by angling the drum approximately 30 degrees from horizontal in an inverted position. In this position, the drum was rotated slightly so as not to embed the closure lugs into the drum as a result of the 30-foot drop. It was determined that this orientation would maximize deformation to the closure ring around the closure lug while still maintaining the extension of the lugs from the package surface. The second drop was from 40 inches above a 40-inch tall 6-inch diameter puncture pin. The package was angled 10 degrees from vertical and aligned over the puncture pin to solidly hit the drum lug(s) in an attempt to disengage the lid when dropped.Tests were performed in response to DOE EM-76 review Q5 inquires that questioned the capability of …
