Upgrade of Doublet III neutral beam injection to long pulse operation
Long pulse physics questions have been raised for auxiliary heated plasma discharges in Tokamaks. A one-second pulse encloses present experiments and is adequate for studying quasi-steady-state operation, whereas, a 5 to 10 second pulse may be required to examine impurity effects of plasma-wall interaction and current profile relaxation. In order to sustain heating in the multi-second pulse range, neutral beam devices must be capable of the same pulse durations. By upgrading the beam collimators, and ion source components, the Doublet III neutral beam injectors can be made to operate with pulses up to 5 seconds in duration with the interpulse period extended to maintain approximately the same duty factor. The scope of the upgrading includes (1) exchanging the accelerator section of the ion source with one having actively cooled tubular grids, and (2) removing or replacing collimators where necessary to stay below 600/sup 0/C peak temperature. An actively cooled ion dump is necessary for pulses substantially longer than 5 seconds. Effects of drift duct choking and induced eddy currents in the cryopanels were examined and found to have a negligible effect on operating the neutral beam injectors up to 5 second pulse duration.

Use of additional fission sources or scattering sources to model inward axial leakages in fast-reactor analysis
When calculations of flux are done in less than three dimensions, bucklings are normally used to model leakages (flows) in the dimensions for which the flux is not calculated. If the net leakage for a given energy group is outward (positive), the buckling is positive, and buckling methods work well. However, if the new leakage for a given energy group is inward (negative), the buckling is negative and can lead to numerical instabilities (oscillations in the iterative flux calculation). This report discusses two equivalent nonbuckling methods to model inward leakages. One method (the chi/sub g/ method) models these incoming neutrons by additional fission sources. The other method (the ..sigma../sub s/(1 ..-->.. g) method) models them by increased downscatter sources. The derivation of the two methods is shown, and the flux spectra obtained by their use are compared with those obtained from two-dimensional (RZ) calculations.

Use of CCDs in the Time-Projection Chamber
The Time-Projection Chamber produces 3-dimensional information about the multiple tracks of reaction products produced by e/sup +/e/sup -/ collisions at the center of the chamber. Two dimensions (r, phi) result from processing signals from proportional wires and induction pads (a total of 17,000 signals) mounted at the end planes. The third (axial) dimension is obtained by measuring the drift time of ionization from the particle tracks to the end planes. To achieve this, all wire and pad signals (suitably shaped to about 500 ns width) are stored in Charge Coupled Devices (CCDs) which, at any moment, hold 45.5 ..mu..s of signal history clocked in at a sampling rate of 10 MHz. About 40 ..mu..s after a master trigger, the history is frozen by stopping the clocking action, and a slow clock mode (20 kHz) is initiated to read out the stored samples which are then digitized (9 bits) and processed by an on-line computer. A total of 17,000 channels x 455 samples (each digitized to 9 bit accuracy) is stored in the CCDs (i.e., about 70M bits) for each event. The pulse shaping philosophy, the design of the CCD units, the drivers and the testing procedures are described.

Utah State Briefing Book for low-level radioactive waste management
The Utah State Briefing Book is one of a series of state briefing books on low-level radioactive waste management practices. It has been prepared to assist state and federal agency officials in planning for safe low-level radioactive waste disposal. The report contains a profile of low-level radioactive waste generators in Utah. The profile is the result of a survey of NRC licensees in Utah. The briefing book also contains a comprehensive assessment of low-level radioactive waste management issues and concerns as defined by all major interested parties including industry, government, the media, and interest groups. The assessment was developed through personal communications with representatives of interested parties, and through a review of media sources. Lastly, the briefing book provides demographic and socioeconomic data and a discussion of relevant government agencies and activities, all of which may impact waste management practices in Utah.

Very-high-level neutral-beam control system
As increasing numbers of neutral beams are added to fusion machines, their operation can consume a significant fraction of a facility's total resources. LBL has developed a very high level control system that allows a neutral beam injector to be treated as a black box with just 2 controls: one to set the beam power and one to set the pulse duration. This 2 knob view allows simple operation and provides a natural base for implementing even higher level controls such as automatic source conditioning.

West Valley demonstration project: alternative processes for solidifying the high-level wastes
In 1980, the US Department of Energy (DOE) established the West Valley Solidification Project as the result of legislation passed by the US Congress. The purpose of this project was to carry out a high level nuclear waste management demonstration project at the Western New York Nuclear Service Center in West Valley, New York. The DOE authorized the Pacific Northwest Laboratory (PNL), which is operated by Battelle Memorial Institute, to assess alternative processes for treatment and solidification of the WNYNSC high-level wastes. The Process Alternatives Study is the suject of this report. Two pretreatment approaches and several waste form processes were selected for evaluation in this study. The two waste treatment approaches were the salt/sludge separation process and the combined waste process. Both terminal and interim waste form processes were studied.

Workshop on Radiological Surveys in Support of the Edgemont Clean-up Action Program
The Nuclear Regulatory Commission, Office of Nuclear Material Safety and Safeguards, has given Pacific Northwest Laboratory (PNL) the responsibility for the development of procedures for the identification of offsite structures and properties in the vicinity of Edgemont, South Dakota, that require remedial action because of elevated radiation levels caused by residual radioactivity as defined in the Uranium Mill Tailings Radiation Control Act of 1978. In order to acquaint interested investigators with the procedures PNL has developed and the measurements that have been performed at Edgemont using these procedures, and also to obtain suggestions for the improvement of these procedures, PNL organized a "Workshop on Radiological Surveys in Support of the Edgemont Clean-up Action Program" on behalf of the Nuclear Regulatory Commission. This workshop was held in Denver on January 21 and 22, 1981. On the first day of the workshop an in-depth discussion of the procedures employed in the entire radiological survey program at Edgemont was held. It included a description of the equipment, techniques and procedures employed in radon daughter measurements within structures, indoor and outdoor gamma radiation surveys, and 226Ra measurements in surface and sub-surface soil samples. On the second day, the results of the measurements that have …

WyCoalGas development feasibility study: site evaluations. Final technical report, November 1980-May 1982. [Proposed WyCoalGas project; Converse County, Wyoming; employee housing possibilities]
The report provides a preliminary assessment of the land development opportunities available to WyCoalGas, Inc. which arise as a consequence of the construction of its proposed Coal Gasification Facility near Douglas, Wyoming. Present thinking indicates that the facility's construction labor force will peak at approximately 3400 workers and permanent work force at approximately 1000 workers, an influx of personnel which will generate significant demands for housing and related support services within Converse County. As part of the permitting process a number of studies are being prepared which identify the environmental and socioeconomic impacts likely to occur as a consequence of the development. The purpose of the following analysis is to recognize that these probable impacts - and the steps necessary to mitigate them - constitute important real estate investment opportunities for WyCoalGas, Inc. In effect, the successful planning and management of these forces represents, at a minimum, the possibility for reduction of total investment costs for the facility; at a maximum, the opportunity for the generation of significant profits from a well-conceived land development program. Several sites are considered from the point of view of planning, ease of development, acquisition possibilities, etc.
