100-DR-1 radiological surveys

This report summarizes and documents the results of the radiological surveys conducted over the surface of the 100-DR-1 Operable Unit, Hanford Site, Richland, Washington. In addition, this report explains the survey methodology using the Ultrasonic Ranging and Data System (USRADS). The 100-DR-1 radiological survey field task consisted of two activities: characterization of the operable unit-specific background conditions and the radiological survey of the operable unit surface area. The survey methodology was based on utilization of USRADS for automated recording of the gross gamma radiation levels at or near 6 in. and at 3 ft from the surface soil. The purpose of the survey is to identify the location of unidentified subsurface radioactive material areas and any surface contamination associated with these areas. The radiological surveys were conducted using both a digital count rate meter with a NaI detector reporting in counts per minute (CPM) and a dose rate meter reporting micro-Roentgen per hour (uR) connected to a CHEMRAD Tennessee Corp. Series 2000 USRADS. The count rate meter was set for gross counting, i.e., Window ``out``. The window setting allows detection of low, intermediate, and high energy photons. The USRADS equipment is used to record the detector readings verses the location …

2F and 2H evaporator loop evaluation closure report (open access)

2F and 2H evaporator loop evaluation closure report

As a result of the Concentrate Transfer System (CTS) tank ventilation system contamination event, a task team was formed to evaluate instrument loops associated with waste reduction equipment. During the event a conductivity probe designed to provide an alarm and initiate an interlock failed to respond to the presence of liquid. An investigation revealed that the probe had become disconnected from the loop. The daily functional check of the conductivity probe circuit only tested the circuit continuity from the ventilation unit to the control room and did not actually test the probe. To test the continuity, a test switch was used to simulate the conducting probe. Because the functional check did not test each part of the loop, the test could be satisfactorily completed even though the probe itself was inoperable. The function of the task team was to develop a list of loops and interlocks prioritized by importance and likelihood of similar failure. The team evaluated the associated loop calibration and functional test procedures to verify that they are adequate to ensure loop performance on a periodic frequency. This report documents the evaluation findings and associated actions required prior to startup of the 2F and 2H evaporators.

First-wall heat-flux measurements during ELMing H-mode plasma (open access)

First-wall heat-flux measurements during ELMing H-mode plasma

In this report we present measurements of the diverter heat flux in DIII-D for ELMing H-mode and radiative diverter conditions. In previous work we have examined heat flux profiles in lower single-null diverted plasmas and measured the scaling of the peak heat flux with plasma current and beam power. One problem with those results was our lack of good power accounting. This situation has been improved to better than 80--90% accountability with the installation of new bolometer arrays, and the operation of the entire complement of 5 Infrared (IR) TV cameras using the DAPS (Digitizing Automated Processing System) video processing system for rapid inter-shot data analysis. We also have expanded the scope of our measurements to include a wider variety of plasma shapes (e.g., double-null diverters (DND), long and short single-null diverters (SND), and inside-limited plasmas), as well as more diverse discharge conditions. Double-null discharges are of particular interest because that shape has proven to yield the highest confinement (VH-mode) and beta of all DIII-D plasmas, so any future diverter modifications for DIII-D will have to support DND operation. In addition, the proposed TPX tokamak is being designed for double-null operation, and information on the magnitude and distribution of diverter …

Investigation of mineral transformations and ash deposition during staged combustion. Quarterly technical progress report, October 1, 1993--December 31, 1993 (open access)

Investigation of mineral transformations and ash deposition during staged combustion. Quarterly technical progress report, October 1, 1993--December 31, 1993

A thorough understanding of the fundamental processes which govern the mineral behavior is essential to the development of tools to predict and manage ash deposition. The purpose of the current project is to perform a fundamental study of mineral transformations and ash deposition during staged combustion of pulverized coal. Staging of combustion air is a strategy used to reduce NO{sub x} emissions from coal-fired units. It is applicable to both advanced combustion systems currently under development (e.g. HITAF) and low NO{sub x} retrofits for existing units. These low NO{sub x} combustion strategies produce fuel rich or reducing conditions in the lower furnace. Therefore, the combustion history of the coal particles is significantly changed from that experienced under normal combustion conditions. A carefully designed experimental study is needed to examine the effects of altered combustion conditions on mineral matter release, fly ash formation, particle stickiness and deposit formation. This project uses state-of-the-art analytical equipment and a well-characterized laboratory combustor to address this need. This report describes work in the initial quarter of a fundamental, three-year study of mineral transformations and ash deposition during staged combustion.

Assist in the Recovery of Bypassed Oil From Reservoirs in the Gulf of Mexico. Final Quarterly Status Report, October 1, 1993--December 31, 1993

Maps collected at the MMS office in New Orleans were planimetered and measured. Measurements of estimated salt diameter and updip areas are also being derived. Production data was read from the tapes obtained in New Orleans and reformatted for use in TORIS. Conceptual work began on the development of the models required to assess unrecovered oil, continued primary recovery of existing mapped oil, updip attic oil recovery, and miscible and immiscible CO{sub 2} injection recovery. Efforts began to supplement existing TORIS data with drilling, workover and facility costs related to past enhanced oil recovery, efforts in the offshore Gulf of Mexico area. Data on CO{sub 2} sources was collected and byproduct CO{sub 2} costs were estimated for use in the economic model. LSU continued the analysis of data obtained from Taylor Energy on the South Marsh Island (SMI) Block 73 Field and the blindcoded Field 2, both in the Gulf of Mexico. The apparatus for experiments for the study of attic oil recovery techniques is being tested. Tests of the 2D adaptive finite element model continue, simulating oil/water flow through porous media. Although coning traces are being produced similar to those in the Lance Hebert thesis, oscillations are still a …

Development of an extraction process for removal of heteroatoms from coal liquids. Technical progress report No. 7, October 1, 1993--December 31, 1993

The objective of this contract is to develop a CO{sub 2}-water extraction process for the removal of heteroatoms from coal-derived naphtha, diesel, and jet fuel. Coal liquids are characterized by their high content of heteroatoms. Conventional techniques could remove the heteroatoms from coal liquids, but at a high hydrogen consumption and at a high cost. A successful development of the CO{sub 2}-water extraction process will increase the environmental acceptability of coal liquids and reduce the H{sub 2} requirements for the upgrading of coal liquids.

Development of improved iron Fischer-Tropsch catalysts. Final technical report: Project 6464 (open access)

Development of improved iron Fischer-Tropsch catalysts. Final technical report: Project 6464

Despite the current worldwide oil glut, the United States will ultimately require large-scale production of liquid (transportation) fuels from coal. Slurry phase Fischer Tropsch (FT) technology, with its versatile product slate, may be expected to play a major role in production of transportation fuels via indirect coal liquefaction. Texas A&M University (TAMU) with sponsorship from the US Department of Energy, Center for Energy and Mineral Resources at TAMU, Texas Higher Education Coordinating Board, and Air Products and Chemicals, Inc., has been working on development of improved iron FT catalysts and characterization of hydrodynamic parameters in two- and three-phase bubble columns with FT derived waxes. Our previous studies have provided an improved understanding of the role of promoters (Cu and K), binders (silica) and pretreatment procedures on catalyst activity, selectivity and longevity (deactivation). The objective of the present contract was to develop improved catalysts with enhanced slurry phase activity and higher selectivity to liquid fuels and wax. This was accomplished through systematic studies of the effects of pretreatment procedures and variations in catalyst composition (promoters and binders). The major accomplishments and results in each of these two main areas of research are summarized here.

Fabrication, phase transformation studies, and characterization of SiC-AlN-Al{sub 2}OC ceramics. Final report

Principal focus was on phase transformation, microstructure development, and elevated temperature creep, with some effort on room- temperature mechanical properties of selected materials. Fabrication was largely hot pressing, although many of the compositions can be densified by pressureless sintering; hot pressing was to ensure full attainment of density with fine microstructure. Most of the work was on SiC-AlN and AlN-Al{sub 2}OC pseudobinaries.

New possibilities for a secure and just world

More than a decade ago individuals from three significant institutions in East Bay Area began discussions in response to the apprehensions that were so deep in the early 1980s. These apprehensions were a result of the intense rhetoric between the two superpowers and the casual commentary about ``limited nuclear war.`` The discussions spoke to the mortal danger as well as to the profound moral question revolving around nuclear arms. The issuance of the US Bishops` Pastoral on War and Peace in 1983 gave the group focus and momentum. The Chancellor at the University of California at Berkeley, the President of the Graduate Theological Union (the consortium of theological schools in Berkeley), and the Director of the Lawrence Livermore National Laboratory (one of the chief designers of American nuclear arms) encouraged us to complete plans for a symposium. It was an era of activism. We chose, however, to serve the theme expressed by Albert Einstein, ``Peace cannot be kept by force, it can only be achieved by understanding.`` After a decade, all of us can commend the leadership of the three institutions and the individuals involved for their perseverance. Their commitments to the pursuit of peace and to the development of …

Program plan: DWPF/HLWDP stirred Melter Program Plan

Slurry Fed Melters (SFM) have been developed in the United States, Europe, and Japan for the conversion of high-level radioactive waste (HLW) to borosilicate glass for permanent disposal. The newest design, the stirred melter, combines the high production rates and high glass quality features of the Joule-heated melters with the low-cost, compact, simple maintenance features of the pot melters. However, further engineering design and demonstrations are needed to operate the stirred melter on a large scale. This document outlines the program which develops a full scale stirred melter for the DWPF (240 pph), and provides a basis which will allow further scale-up of the technology for use in the Hanford High Level Waste Disposal Program (HLWDP) for up to four times the reference capacity.
