Analysis of organics in 643-G groundwaters by GC/MS

Description: Twenty-three of the 63 monitoring wells in the 643-G burial ground consistently contain measurable (> 1 ppm) amounts of total organic carbon, TOC. Of these 23 wells, 10 that contain elevated (2--400 ppm) TOC were chosen for in-depth analysis of semivolatile organics by gas chromatography/mass spectrometry, GC/MS. A well located near the site of previous decontamination operations was also chosen for analysis. About 40% of the organic compounds detected in these well waters have been identified. Many of these compounds are indicative of liquid scintillation wastes, spent solvent wastes, and solvent degradation products. Four priority pollutants were present at low levels. Some of the organics identified are probably degradation products from humic substances. Organic compounds of unknown origin are also present. No strong chelators capable of increasing radionuclide mobility have been identified. Preliminary dialysis work indicates that up to 30--40% of the TOC may be present as nonvolatile humic substances that cannot be analyzed by GC/MS.

A study of mechanical processing damage in brittle materials. Progress report, 1 August 1984--28 February 1985

Description: The authors are continuing their work on developing the necessary methods for the nondestructive evaluation of machining damage in structural ceramics. Machining operations such as grinding, cutting, and polishing induce slot-like cracks in ceramic materials and lead to a marked decrease in their strength. The presence of compressive surface residual stress, which is responsible for crack mouth closure, leads to slow crack growth and a further reduction in strength. They are continuing the study of the effect of single isolated cracks and have just begun to look at the problem of multiple cracks due to grinding damage. In the last reporting period, the authors studied the effect of isolated cracks on the strength of ceramic components. They used a pulse-echo acoustic technique to measure the scattering coefficient of the crack to surface acoustic waves as a function of frequency. In the presence of compressive surface residual stress, the cracks are closed at the surface and their scattering coefficient exhibits a characteristic null that allows for the determination of the crack depth using the acoustic pulse-echo technique. Thus, they find it possible to evaluate the crack sizes in the seeded samples, and the reduction in strength engendered with very good accuracy. The authors are presently in the middle of a study of a set of twelve samples with isolated seeded cracks. Plans for further studies are described.

Final report on the sampling and analysis of sediment cores from the L-Area oil and chemical basin

Description: Nine vibracores were collected in the L-Area oil and chemical basin (904-83G) during late March and early April 1985. These cores were collected for analysis of the sludge on the basin floor and the underlying sediment. Several different field and laboratory analyses were performed on each three inch segment of all the cores. These included: (1) Sediment characterization; (2) Percent moisture; (3) Dry weight; (4) Spectral gamma analysis; (5) Gross alpha and beta analysis. Detailed chemical analysis were measured on selected intervals of 2 cores (LBC-5 and 6) for complete chemical characterization of the sediments. This sampling program was conducted to provide information so that a closure plan for the basin could be developed. This report describes the methods employed during the project and provide a hard copy of the analytical results from the sample analyses. Included in the appendices are copies of all field and laboratory notes taken during the project and copies of the gas chromatograms for the petroleum hydrocarbon analysis. All chemical results were also submitted on a 5-inch floppy disk.

Report of the Attorney General to the Safe Growth Cabinet Council

Description: On January 7, 1983, President Reagan signed into law the Nuclear Waste Policy Act (NWPA), 42 U.S.C. {section} 10101 et seq. As part of the Act, the Congress of the United States authorized construction of a permanent deep geologic repository in an effort to solve the nation`s problem with disposal of spent nuclear fuel and high-level radioactive waste. Congress also directed the Department of Energy (DOE) to study the need for and feasibility of constructing a monitored retrievable storage (MRS) facility. Also in late April of 1985, the State of Tennessee was informed that three potential sites for the MRS had been selected in Tennessee. The locations included the site of the abandoned Clinch River Breeder Reactor Project, a site on DOE`s Oak Ridge Reservation, and the site of the abandoned Hartsville nuclear power plant. This report covers the legal aspects of the potential project completed during the period September 1, 1985--November 30, 1985.

PSP Program close out documentation

Description: In December 1982 DOE-SR directed SRL to study the feasibility and impact of a program to lower the U-236 content of the Highly Enriched Uranium (HEU) stockpile used as fuel for the SRP reactors. In response to this request SRL assessed four technologies, Atomic Vapor Laser Isotope Separation (AVLIS), Molecular Laser Isotope Separation (MLIS), Gas Centrifuge, and the Plasma Separation Process (PSP) for this purpose with the assistance of the Engineering Department. In April 1983 cost/benefit analyses for these processes, high spot cost estimates for production facilities, and process uncertainties were submitted to DOE-SR with a recommendation to proceed with the conceptual design and supporting development programs for a facility based on the use of the PSP process. The current program status for the PSP development program at SRL and the design and documentation of a production facility at SRP, referred to as the Fuel Improvement Demonstration Facility (FIDF), is described in this report.

Calculations of volatilities of Hg, NH{sub 3}, and Cs-137 in the F/H Effluent Treatment Facility evaporator system

Description: An evaporator will be used in the F/H Effluent Treatment Facility (F/H ETF) to reduce the volume of effluent dispensed to Upper Three Runs Creek and to concentrate solutions from three sources in the F/H ETF before sending that waste to Saltstone. The evaporator will be fed by backwash from the filters in the filtration unit, the concentrate stream from reverse osmosis, and the solutions used in regeneration of ion exchange columns. These streams will contain small amounts of Hg, NH{sub 3}, and Cs-137. Data is readily available concerning the entrainment of these chemicals in evaporator overheads during an evaporation process. No data has yet been generated to predict their behavior due exclusively to their volatility, however. This document describes calculations that have been made concerning the volatility of Hg, NH{sub 3}, and Cs-137 compounds in the F/H ETF evaporator based on expected concentrations, temperatures, and flow rates in that facility.

EP-toxicity test of saturated GT-73 resin and resin in grout

Description: The results of EP-toxicity tests on mercury saturated Duolite{reg_sign} GT-73 cation exchange resin clarify options for the ultimate disposal of spent resin. Samples of GT-73 saturated with mercury passed the EP-toxicity test, indicating that fully spent resin may be classifed as ``solid``-not``hazardous``-waste and stored or disposed-of as such. Samples of GT-73 resin saturated with mercury and then incorporated into Portland Type 1 cement did not pass the EP-toxicity test and fall into the ``hazardous waste`` category. Samples of GT-73 resin less-than-saturated with mercury which were in corporated in Portland Type 1 cement passed the EP-toxicity test and may be classified as ``solid waste.`` Other commercially available materials are being investigated for incorporating fully spent GT-73 resin in a solid waste form.

Hydroxide depletion in dilute supernates stored in waste tanks

Description: Free hydroxide ion in dilute supernates are depleted by reaction with atmospheric carbon dioxide to form bicarbonate and carbonate species and by reaction with acidic compounds formed by the radiolytic decomposition of tetraphenylborate salts. A model of the kinetics and thermodynamics of absorption of carbon dioxide in the waste tanks has been developed. Forecasts of the rate of hydroxide depletion and the requirements for sodium hydroxide to maintain technical standards have been made for the washed sludge and washed precipitate storage tanks. Hydroxide depletion is predicted to have a minimal impact on sludge processing operations. However, in-tank precipitation and downstream DWPF operations are predicted to be significantly affected by hydroxide depletion in Tank 49H. The installation of a carbon dioxide scrubber on Tank 49H may be justified in view of the decrease in alkali content and variation in the melter feed.

Evaluation of the need, feasibility, and siting of the MRS in Tennessee. Draft final report

Description: This summary report outlines the results of an independent assessment of the need, feasibility, and siting of the proposed Monitored Retrievable Storage (MRS) facility. The detailed reports of this assessment are included as appendices to the summary report. The Department of Energy (DOE) has concluded that the MRS is not absolutely necessary, but preferred, in order to manage and move spent fuel from reactors to a repository. The team has attemped to assess ``need`` by comparing to advantages and disadvantages of various systems, with and without the MRS. ``Feasibility has been assessed by comparing the technical and economic advantages and disadvantages. The team was not asked to recommend a preferred system. That choice will depend on the importance that are used to compare alternatives. The five key criteria selected by the team for comparing alternate systems were: economic cost, radiological risk, non-radiological transportation impacts, the likelihood of successful implementation and operation of the system, and the likelihood of meeting the schedule in the Nuclear Waste Policy Act. The team compared twelve different systems and modeled the transportation impacts and risks with three repository sites and two MRS sites.

Recommendations on the proposed Monitored Retrievable Storage Facility

Description: Following the Department of Energy`s announcement in April 1985 that three Tennessee sites were to be considered for the Monitored Retrievable Storage facility, Governor Lamar Alexander initiated a review of the proposal to be coordinated by his Safe Growth Team. Roane County and the City of Oak Ridge, the local governments sharing jurisdiction over DOE`s primary and secondary sites, were invited to participate in the state`s review of the MRS proposal. Many issues related to the proposed MRS are being considered by the Governor`s Safe Growth Team. The primary objective of the Clinch River MRS Task Force has been to determine whether the proposed Monitored Retrievable Storage facility should be accepted by the local governments, and if so, under what conditions. The Clinch River MRS Task Force is organized into an Executive Committee cochaired by the Roane County Executive and Mayor of Oak Ridge and three Study Groups focusing on environmental (including health and safety), socioeconomic, and transportation issues.

An economic analysis of a monitored retrievable storage site for Tennessee. Final report and appendices

Description: The United States Department of Energy is charged with the task of identifying potential sites for a Monitored Retrievable Storage (MRS) Facility and reporting the results of its analysis to Congress by January 1986. DOE chose three finalist sites from 11 sites DOE analysts evaluated earlier. All three are in Tennessee, including two in Oak Ridge and one in Trousdale/Smith Counties. This paper is a summary of research undertaken on the economic effects of establishing the MRS facility in Tennessee. All three locations were considered in the analysis, but on some occasions attention is focused on the site preferred by DOE. The research was undertaken by the Center for Business and Economic Research (CBER), College of Business Administration, the University of Tennessee, Knoxville, under contract with the Tennessee Department of Economic and Community Development.

Cancer radioimmunotherapy: Development of an effective approach. Progress report, 1985

Description: The objective of this program is the development of effective approaches for delivering radiation therapy to patients with cancer using radiopharmaceuticals produced from monoclonal antibodies. One major achievement of this program has been the development of a new, Cu-67 chelator (Teta). This chelator firmly holds copper even in the presence of competitive serum proteins. Copper has proven to be labile with other chelators. Also, a single photon emission tomographic camera was purchased with University and philanthropic funds specifically for this program. This allows full-time developmental work on quantitative imaging approaches and in vivo kinetics of our various radiopharmaceutical antibody products. The pharmakinetics of I-123 antibody and antibody fragments have been obtained in patients utilizing quantitative imaging and have demonstrated significant differences as well as the need for long- term studies with I-131 and Cu-67.

Computer programs for developing source terms for a UF{sub 6} dispersion model to simulate postulated UF{sub 6} releases from buildings

Description: Calculational methods and computer programs for the analysis of source terms for postulated releases of UF{sub 6} are presented. Required thermophysical properties of UF{sub 6}, HF, and H{sub 2}O are described in detail. UF{sub 6} reacts with moisture in the ambient environment to form HF and H{sub 2}O. The coexistence of HF and H{sub 2}O significantly alters their pure component properties, and HF vapor polymerizes. Transient compartment models for simulating UF{sub 6} releases inside gaseous diffusion plant feed and withdrawl buildings and cascade buildings are also described. The basic compartment model mass and energy balances are supported by simple heat transfer, ventilation system, and deposition models. A model that can simulate either a closed compartment or a steady-state ventilation system is also discussed. The transient compartment models provide input to an atmospheric dispersion model as output.
