Postirradiation Testing Laboratory (327 Building) (open access)

Postirradiation Testing Laboratory (327 Building)

A Standards/Requirements Identification Document (S/RID) is the total list of the Environment, Safety and Health (ES and H) requirements to be implemented by a site, facility, or activity. These requirements are appropriate to the life cycle phase to achieve an adequate level of protection for worker and public health and safety, and the environment during design, construction, operation, decontamination and decommissioning, and environmental restoration. S/RlDs are living documents, to be revised appropriately based on change in the site`s or facility`s mission or configuration, a change in the facility`s life cycle phase, or a change to the applicable standards/requirements. S/RIDs encompass health and safety, environmental, and safety related safeguards and security (S and S) standards/requirements related to the functional areas listed in the US Department of Energy (DOE) Environment, Safety and Health Configuration Guide. The Fluor Daniel Hanford (FDH) Contract S/RID contains standards/requirements, applicable to FDH and FDH subcontractors, necessary for safe operation of Project Hanford Management Contract (PHMC) facilities, that are not the direct responsibility of the facility manager (e.g., a site-wide fire department). Facility S/RIDs contain standards/requirements applicable to a specific facility that are the direct responsibility of the facility manager. S/RlDs are prepared by those responsible for managing …

Radioactive effluents in Savannah River. Summary report for 1996 (open access)

Radioactive effluents in Savannah River. Summary report for 1996

During 1996, the radioactive effluents in the Savannah River were generally comparable to (or lower than) those observed during the earlier years of these studies, being orders of magnitude below DOE and EPA/CFR guide levels. Relative to SRS and Plant Vogtle, the upstream site at Shell Bluff and the downstream side at Highway 301 Bridge are the only resin sampler sites still in service. Vogtle associated activities were largest during June to August, and they are dominated by {sup 60}Co as was the case in 1995. In earlier years, Vogtle effluents had been dominated by {sub 58}Co. The maximum observed {sub 58}Co and {sub 60}Co were 52 fCi/L and 162 fCi/L; however, values an order of magnitude greater are projected just downstream of Plant Vogtle, as noted earlier. In addition to {sub 58}Co and {sub 60}Co, Vogtle activities for {sub 54}Mn was correlated. SRS associated gamma activities were for {sub 137}Cs, which were observed at levels consistent with known SRS sources. In 1996, an isotope-specific resin was used for cesium collection, and this resulted in a maximum observed {sub 137}Cs of 85 fCi/L at Highway 301 Bridge. The standard resin yielded a maximum of 54 fCi/L, which is comparable to …

Monitoring and data analysis for the Vadose Zone Monitoring System (VZMS), McClellan AFB. Quarterly status report (open access)

Monitoring and data analysis for the Vadose Zone Monitoring System (VZMS), McClellan AFB. Quarterly status report

This report contains information on field and laboratory work performed between January and May 15th 1997 at site S-7 in IC 34, at McClellan AFB. At this location, a Vadose Zone Monitoring System (VZMS) is currently being used to collect subsurface data including hydraulic potential, soil gas pressure, moisture content, water chemistry, gas chemistry, and temperature. Due to delays in the completion of the above-ground installations, data collection did not commence until mid-February. As a result, the data presented in this report is preliminary.

Test plan for composting studies involving weight and volume reduction of leaf and stalk biomass: DOE/OTD TTP{number_sign} SR17SS53 {ampersand} TTP{number_sign} SR18SS41 (open access)

Test plan for composting studies involving weight and volume reduction of leaf and stalk biomass: DOE/OTD TTP{number_sign} SR17SS53 {ampersand} TTP{number_sign} SR18SS41

SRTC and a panel of experts from off-site previously determined that composting was the most attractive alternative for reducing the volume and weight of biomass that was slightly radioactive. The SRTC proposed scope of work for Subtask 2 of TTP{number_sign} SR17SS53 and TTP{number_sign} SR18SS41 involves bench scale studies to assess the rates and efficiencies of various composting schemes for volume and weight reduction of leaf and stalk biomass (SB). Ultimately, the data will be used to design a composting process for biomass proposed by MSE for phytoremediation studies at SRS. This could drastically reduce costs for transporting and disposing of contaminated biomass resulting from a future major phytoremediation effort for soil clean-up at the site. The composting studies at SRTC includes collaboration with personnel from the University of Georgia, who will conduct chemical analyses of the plant material after harvest, pre-treatment, and composting for specific time periods. Parameters to be measured will include: lignin, hemicellulose, cellulose, carbon and nitrogen. The overall objective of this project is to identify or develop: (1) an inexpensive source of inoculum (consisting of nutrients and/or microorganisms) capable of significantly enhancing biomass degradation, (2) an optimum range of operating parameters for the composting process, and (3) …

An integrated study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County Texas. Quarterly report, January 1--March 31, 1997 (open access)

An integrated study of the Grayburg/San Andres Reservoir, Foster and South Cowden Fields, Ector County Texas. Quarterly report, January 1--March 31, 1997

The goals of work done this quarter were (1) to analyze the preliminary seismic inversion model for the Grayburg A, B, and C sequences and the upper San Andres formation; (2) modify the inversion model to improve its accuracy and to include the deeper Holt Formation; and (3) test various rock property quantities against the improved model and other seismic attributes using refined analysis boundaries. A satisfactory inversion model and porosity analysis remains to be accomplished, but much has been learned about the modeling and analysis processes. Qualitative comparison of sonic logs with the inversion model traces in profile view shows great similarity and success is being made toward good quantitative results. Progress on these goals is described. Additional studies were carried out on the following: Witcher No. 12 core and completion, water analyses, reservoir simulation, reservoir engineering, and water quality for injection.

Two-dimensional synthesis: Ultrathin porous membranes. Final report, December 1, 1993--November 30, 1996 (open access)

Two-dimensional synthesis: Ultrathin porous membranes. Final report, December 1, 1993--November 30, 1996

The proposed proof of concept has been accomplished. We have synthesized an ultrathin (7 {angstrom}) covalent molecular grid of the proposed type, composed of 2.5 nm x 2.5 run squares with 1.5 nm x 1. 5 nm square openings, we have demonstrated that it is sturdy (boiling with alcoholic HCl and surface-to-surface transfer), and we have obtained its spectral and STM characterization. The synthesis was based on the originally proposed two-dimensional linear cross-coupling of oriented molecular connectors mounted on pedestals that were constrained to a two-dimensional liquid mercury surface, but the molecules actually used in the successful experiment were different from those intended originally. In this first attempt, only small sheets of the grid were made (up to 0.15 {mu} x 0.15 {mu}), and they did not have long-range order. Both of these problems were undoubtedly caused by the use of an irreversible coupling reaction in the polymerization process, and by the use of a coupler that was not strictly linear and thus permitted easy formation of defects (pentagons instead of squares, etc.). Neither of these limitations are inherent, and we have already submitted research proposals in which we outline how we propose to do the polymerization in a reversible …
