Recent experimental investigations indicate that the repair welding of irradiated materials containing greater than 1 to 2.5 appm helium leads to catastrophic cracking in the heat affected zone of the weld. The high temperatures and cooling tensile stresses which occur during the welding process lead to enhanced helium bubble growth in the heat affected zone region, resulting in catastrophic cracking upon cooling. An investigation is proposed which seeks to determine the effect of stress state on the helium bubble growth process and develop engineering modifications to the welding process based upon this understanding in an attempt to alleviate or eliminate the weld cracking problem in type 316 stainless steel materials.

The purpose of this study was to characterize typical levels and variability of 60Hz magnetic fields at the centerline and edge of right-of-way of Bonneville Power Administration (BPA) 230-kV and 500-kV transmission lines. This was accomplished by taking magnetic field measurements at over 800 spans in Oregon and Washington. The spans were sampled using a stratified random sampling procedure with region (East vs. West), voltage (230-kV vs 500-kV), and circuit configuration as strata. There were five different circuit configuration groups for each region/voltage category requiring a total of 200 strata. Magnetic field measurements were taken at 13 locations under each span using an EMDEX-C as a survey meter. Additional information recorded for each span included conductor height (at 10 locations), right-of-way width, longitudinal and lateral slope, time of day, vegetation, terrain, weather conditions, temperature, wind speed, span length and presence of other lines in the corridor. 9 refs., 17 figs., 26 tabs.

The efficiency of soft x-ray production from laser-irradiated plasmas is simulated for two different spectral regions. These two regions, 14{Angstrom} {plus minus} 15% and 130{Angstrom} {plus minus} 1%, were chosen for proximity mask or point-projection technological applications. Relatively large conversion efficiencies were obtained from irradiation of a stainless steel target using the conditions suggested by recent Hampshire Instruments' experiments for proximity masking. Pulse-width and laser frequency parameter studies were performed for point-projection applications which suggest that the conversion applications which suggest that the conversion efficiency is sensitive to pulse-width but not to laser frequency. One of the critical components of any x-ray lithographic scheme is of course the x-ray laser source. There are two primary contenders for a reliable, efficient source currently: synchrotron radiation and spectral emission from laser produced plasma. The dominant issue for laser-plasma emission is the conversion efficiency -- output in the intended operating spectral region relative the required incident laser energy. Simulations are described in the following for both high and low energy spectral regions which have been suggested by either the proximity masking or point-projection technology.

A simple mixing-length estimate of diffusion of alphas particles by toroidicity-induced shear Alfven eigenmodes (TAE) is used, in zero and one-dimensional models, to evaluate the importance of diffusion of meeting ignition requirements for ITER and other next-generation burning plasma experiments. It is found that, depending on a number of assumptions, diffusion could reduce that effectiveness of alpha heating in the core as much as an order of magnitude. However, the effect would be less if only alphas resonant with the Alfven waves diffuse. Also, in the Appendix it is argued that the mixing length diffusion formula, though qualitatively reasonable, may be an over estimate. 12 refs., 7 figs., 1 tab.

Task 3 provides detailed characterization of fuel properties of the test coals and in-depth evaluation of their performance characteristics under controlled pilot-scale combustion testing. Results from this task provide fundamental information required to develop some of the improved algorithms for the CQE. Both bench-scale fuel characterization and test furnace performance evaluations are being performed under this task. All pilot-scale combustion tests under this task have been completed. Topical reports for the coals evaluated under the Public Service Oklahoma's Northeastern Unit 4 and Northern States Power's King Unit 1 test series have been issued. Work continued during the past quarter on preparation of the final report for the Mississippi Power Company's Watson Unit 4 tests (to be completed first quarter 1993) and analyzing pilot-scale combustion data from the Alabama Power Company's Gaston tests; a topical report for the Gaston study will also be issued in 1993. Bench-scale testing and data analyses continued in support of the development of the slagging and fouling models. Data obtained from the analysis of samples of deposits, inflame solids, fly ash, and coal from CQE pilot-scale and drop tube combustion tests were evaluated for use in devising and verifying the slagging and fouling algorithms.

This quarterly report discusses the technical progress of a US Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO[sub x]) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company's Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commercially available tangentially-fired low NO[sub x] combustion technologies on NO[sub x] emissions and boiler performance. A target of achieving fifty percent NO[sub x] reduction using combustion modifications has been established for the project. The stepwise approach that is being used to evaluate the NO[sub x] control technologies requires three plant outages to successively install the test instrumentation and the different levels of the low NO[sub x] concentric firing system (LNCFS). Following each outage, a series of four groups of tests are performed. These are (1) diagnostic, (2) performance, (3) long-term, and (4) verification. These tests are used to quantify the NO[sub x] reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. This technical progess report presents the …

The common theme of the research is the effects of electronic interactions on the properties of systems. Specifically, work was done in the following areas: magnetically modulated systems, Raman and EELS in superlattices, ballistic quantum interference effects, quantum dot arrays, and optical response of undoped fullerene crystals.

This report was conducted to: (1) develop an understanding of causes for the vast differences between the two comprehensive studies, and (2) using a methodology consistent with the reconciled methods employed in the two studies, develop a single seismic hazard for the Savannah River Site suitable for use in seismic probabilistic risk assessments with emphasis on the K Reactor. Results are presented for a rock site which is a typical because detailed evaluations of soil characteristics at the K Reactor are still in progress that account for the effects of a soil stablizing grouting program. However when the soils analysis is completed, the effects of soils can be included with this analysis with the addition of a single factor that will decrease slightly the seismic hazard for a rock site.

The State Heating Oil and Propane Price (SHOPP) survey for the 1993--1994 heating season was conducted by the Pennsylvania Energy Office (PEO) in conjunction with the US Department of Energy, Energy Information Administration (DOE/EIA). The objective of the program was to collect price information for residential No. 2 heating oil and propane. Prices were to be collected on the first and third Mondays of each month, starting on October 4, 1993, and extending through March 21, 1994. When the survey started on October 4, 1993, the average No. 2 charge price for residential customers was 85.0 cents per gallon. On January 31, the DOE requested that the survey be conducted on a weekly basis. An extended period of extremely cold weather had increased demand for petroleum products. The seasonal high of 94.7 cents was reached on February 14, 1994. The price average declined to 91.8 cents on March 21, at the conclusion of the survey. This was an increase of 8.0 percent for the season. The results of the October 4, 1993, price survey indicated an average unweighted price of 108.9 cents per gallon for a residential customer. The average price rose to 116.2 cents on March 21, for a …

Five diaphragm seal specimens for the W79 retrofit program were welded and burst tested to meet requirements for the Engineering Evaluation (EE). The average burst pressure for these five diaphragm specimens was 11500 psi. All failures greatly exceeded the drawing requirements placed upon the system. After burst testing the specimens, the authors performed scanning electron microscopy on all five specimens to ensure ductile failure and cross-sectioned two specimens to characterize the weld morphology. The metallographic analysis showed these parts to be typical of high quality thin-section weldments. Analysis of heat flow during welding also has been included in this report. Thermal profiles easily meet those required by assembly specifications. Maximum temperatures achieved during welding were 520{degrees}C in the diaphragm area and 80{degrees}C on the bottom of the block.
