Repair Welding of Fusion Reactor Components
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.

Survey of Magnetic Fields Near BPA 230-kV and 500-kV Transmission Lines.
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.

Laser produced plasma soft x-ray generation
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.

Implications of TAE modes for the design of ITER
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.

Development of a Coal Quality Expert
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.

Innovative Clean Coal Technology (ICCT): 180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO[sub x]) emissions from coal-fired boilers
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 …

Seismic hazard for the Savannah River Site: A comparative evaluation of the EPRI and LLNL assessments
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.
