This report provides a qualitative and semiquantitative description of the chemical reaction that decomposed the excess sodium tetraphenylborate in Tank 48H during November and December 1995.

An international team was assembled for the purpose of selecting suitable immobilization forms and processing technologies for the Fissile Materials Deposition Program Office. As a reference point, the team used the NAS study but did not limit their recommendations to those of the NAS. As a result, two basic forms were selected and the processing alternatives to provide those two forms were defined. Environmental data have been supplied to support a preliminary environmental impact statement for the disposition program. The immobilization program has also entered the R&D Phase and progress has been made on the formulation of both glass and ceramic forms. Samples of both glass and ceramics containing tens of grams of plutonium have been prepared which indicate that the required concentration range can be obtained. Long-term leach tests to verify performance requirements in the repository are also under way.

This report shows the methods used to test the stack gas outlet concentration and emission rate of Volatile Organic Compounds as Total Non-Methane Hydrocarbons in parts per million by volume,grams per dry standard cubic meter, and grams per minute from the PUREX ETF stream number G6 on the Hanford Site. Test results are shown in Appendix B.1.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Electrochemical capacitative behavior of carbon aerogels and commercial carbon fiber cloths was studied in 5M KOH, 3M sulfuric acid, and 0.5M tetrethylammonium tetrafluoroborate/propylene carbonate electrolytes. The resorcinol-formaldehyde based carbon aerogels with a range of denisty (0.2-0.85 g/cc) have open-cell structures with ultrafine pore sizes (5-50 nm), high surface area (400-700 m{sup 2}/g), and a solid matrix composed of interconnected particles or fibers with characteristic diameters of 10 nm. The commercial fiber cloths in the density range 0.2-04g/cc have high surface areas (1000-2500 m{sup 2}/g). The volumetric capacitances of high-density aerogels are shown to be comparable to or exceeding those from activated carbon fibers. Electrochemical behavior of these materials in various electrolytes is compared and related to their physical properties.

This paper examined effects of heat treatment and milling (before or after heat treatment) on the (electrochemical) intercalating ability of needle petroleum coke; natural graphite particles are included for comparison. 1 tab, 4 figs, 7 refs.

This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development Department (WPDD) as specified in the Waste Package Implementation Plan (pp. 4-8, 4-11, 4-24, 5-1, and 5-13, Ref. 5.10) and the Waste Package Plan (pp.3-15, 3-17, and 3-24, Ref. 5.9). The design data request addressed herein is: Characterize the preliminary 21 pressurized water reactor (PWR) advanced (A) uncanistered fuel (UCF) waste package (WP) to show that the design is feasible for use in the MGDS environment. The purpose of this analysis is to respond to a concern that the long-term disposal thermal issues for the UCF WP do not preclude UCF WP compatibility with the MGDS. The objective of this analysis is to provide thermal parameter information for the preliminary UCF WP design under nominal MGDS repository conditions. The results are intended to show that the design has a reasonable chance to meet the MGDS design requirements for normal MGDS operation and to provide the required guidance to determining the major design issues for future design efforts. Future design efforts will focus on UCF design changes as further design and operations information becomes available.

The Department of Energy (Department), Nevada Operations office (Nevada) is responsible for following established policy in obtaining necessary support services through its Contract Management Division. The objective of the audit was to determine whether Nevada and its Management and Operating (M&O) contractors were following Federal and Department policies with regard to directed support service subcontracts. The audit showed that program offices in Nevada and Headquarters were directing the Nevada M&O contractor to award subcontracts to specific companies or individuals. The subcontractors reported either directly to a program office or to a national laboratory. Furthermore, the subcontractors` work products were delivered directly to the requesting program office. The M&O contractor had only administrative responsibility for the subcontracts awarded. This occurred because Nevada had not established adequate internal controls over the process of procuring support service. As a result, the M&O contractor was paid a higher award fee for managing the Department`s contracts and may have incurred additional costs in staffing its procurement office. We recommended that the Manager, Nevada Operations Office, discontinue directed support service subcontracts to its M&O contractor and act to strengthen internal controls over subcontracting. Nevada management partially concurred with the recommendations but did not believe the directed …
