Theoretical interpretation of angle- and polarization-dependent laser light absorption measurements
It is shown that recently published observations of angle- and polarization-dependent absorption of intense laser light are consistent with computer simulations of resonance absorption in a steepened plasma profile, with the additional assumption of a modestly rippled critical surface. About 10% absorption seems to be due to mechanisms not addressed in the simulations.

Laboratory experiment demonstrating the way in which a steam barrier prevents the dissolution of salt buried in a flooded packed bed. [Implications for preventing radionuclide migration near groundwater in underground explosions]
We have conducted a laboratory experiment to demonstrate a way in which a solid material can be prevented from dissolving in water. The differential solubility of salt (NaCl) in steam vs water is exploited. As long as the temperature of the area and water surrounding the salt is maintained above the boiling point of water, the salt cannot dissolve. This phenomenon, known as the thermal barrier, has far-reaching implications for preventing the dispersal of contaminants present near groundwater sources (e.g., created by underground explosions).

Very high-spin states in nuclei. [. gamma. spectra]
The continuum ..gamma..-ray spectrum following neutron emission in a (HI,xn) reaction consists of a high-energy tail, the statistical cascade, and a lower-energy bump, the yrast cascade, which contains most of the intensity and consists mostly of stretched E2 transitions. Thus, a good approximation to the average angular momentum carried by the ..gamma..-rays is 2N/sub ..gamma../-bar. Under favourable conditions, effective moments of inertia can be deduced for states up to the top of the ..gamma..-ray cascade. The maximum angular momentum in the cascades is probably limited by ..cap alpha..-emission for nuclei with A < 150 and by fission for those with A > 150. 17 figures.

Nonlinear dynamics of the electron self-field interaction
There has been recent interest in the formulation of a nonperturbative theory of quantum electrodynamics (QED). In this report we critically discuss a recent theory of nonperturbative QED. We point out a difficulty with this theory and outline a theory which is free of this difficulty. Finally, computational schemes for implementing the theory are briefly discussed.

Computer simulations of high pressure systems
Numerical methods are capable of solving very difficult problems in solid mechanics and gas dynamics. In the design of engineering structures, critical decisions are possible if the behavior of materials is correctly described in the calculation. Problems of current interest require accurate analysis of stress-strain fields that range from very small elastic displacement to very large plastic deformation. A finite difference program is described that solves problems over this range and in two and three space-dimensions and time. A series of experiments and calculations serve to establish confidence in the plasticity formulation. The program can be used to design high pressure systems where plastic flow occurs. The purpose is to identify material properties, strength and elongation, that meet the operating requirements. An objective is to be able to perform destructive testing on a computer rather than on the engineering structure. Examples of topical interest are given.

Assessment of high temperature nuclear energy storage systems for the production of intermediate and peak-load electric power
Increased cost of energy, depletion of domestic supplies of oil and natural gas, and dependence on foreign suppliers, have led to an investigation of energy storage as a means to displace the use of oil and gas presently being used to generate intermediate and peak-load electricity. Dedicated nuclear thermal energy storage is investigated as a possible alternative. An evaluation of thermal storage systems is made for several reactor concepts and economic comparisons are presented with conventional storage and peak power producing systems. It is concluded that dedicated nuclear storage has a small but possible useful role in providing intermediate and peak-load electric power.

Development and evaluation of DOP generators for special uses
The Environmental Standards Group at Mound Laboratory uses ''cold'' DOP generators to produce background aerosol concentration for testing HEPA filters in clean-room operations. Two simple, portable, air-operated aerosol generators were built and tested to determine their performance. The results show the particle size distribution is in the 0.3 to 0.8 ..mu..m range and that /sup 1///sub 4/ or /sup 3///sub 8/ in. i.d. tubing to the nozzles should be used.

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.

High efficiency shale oil recovery
The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated at bench-scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a larger continuous process kiln. For example, similar conditions of heatup rate, oxidation of the residue and cool-down prevail for the element in both systems. This batch kiln is a unit constructed in a 1987 Phase I SBIR tar sand retorting project. The kiln worked fairly well in that project; however, the need for certain modifications was observed. These modifications are now underway to simplify the operation and make the data and analysis more exact. The second quarter agenda consisted …

Survey of technology for storage of thermal energy in heat transfer salt
The widespread use of nitrate-based fused salt mixtures as heat transport media in the petroleum and chemical process industries and in metallurgical heat-treatment operations has led to the development of satisfactory equipment for handling and containing these materials. A mixture known as heat transfer salt (HTS), which is composed of 40 percent NaNO/sub 2/, 7 percent NaNO/sub 3/, and 53 percent KNO/sub 3/ by weight, has been used commercially in large quantities as a heat transfer fluid. It has been suggested that this salt be used for storing energy as sensible heat in the temperature range 200 to 540/sup 0/C (400 to 1000/sup 0/F). The eutectic 54 percent KNO/sub 3/--46 percent NaNO/sub 3/ by weight known as ''draw salt,'' which has undergone less testing but is more stable thermally and more attractive economically than HTS and has similar physical properties, may be a desirable alternative. Several specific energy storage applications, such as intermediate-load and peaking electric power, solar energy, and energy from fluidized-bed coal burners, are discussed. Long-term stability and corrosion data on these salts are presently available only to approximately 480/sup 0/C. However, for the design and construction of energy storage facilities to operate over many years at temperatures …

Rydberg series in the lanthanides and actinides observed by stepwise laser excitation
The techniques of stepwise laser excitation were applied to obtain Ryberg series in the lanthanides and in uranium. The methods employed circumvent many of the experimental difficulties inherent in conventional absorption spectrosopy of these heavy atoms with very complex spectra. The Rydberg series observed have allowed the determination of accurate ionization limits. The values in eV are: Ce, 5.5387(4);Nd, 5.5250(6); Sm, 5.6437(10); Eu, 5.6704(3); Gd, 6.1502(6); Tb, 5.8639(6); Dy, 5.9390(6); Ho, 6.0216(6); Er 6.1077(6); U, 6.1941(5). A comparison of the f/sup n/s/sup 2/-f/sup n/s ionization limits as a function of n with theoretical calculations is made.

Radiation stability of a hydrogen getter material (DPPE). [Dimerized phenyl propargyl ether containing Pd on CaCO/sub 3/ catalyst]
An investigation was made on a hydrogen getter material (DPPE) to determine its radiation stability. Such material has potential for nuclear industry applications. The material is composed of 75 percent of an unsaturated organic compound (1,6-diphenoxy-2,4-hexadiyne) and 25 percent catalyst (5 percent palladium on calcium carbonate). The radiation stability of this material and of the hydrogenated product was determined by exposing them to gamma radiation in air and vacuum and analyzing for radiolysis products and hydrogen capacity. The major products formed were phenol and carbon dioxide. Numerous solid compounds were also formed in much smaller yields. Product yields were much larger in air than in vacuum. Hydrogen uptake curves showed that the hydrogen capacity decreased appreciably after an absorbed dose of about 10/sup 8/ rads, and that irradiation is more detrimental in air than in vacuum. (For SI (metric) use: rads have been replaced by grays (Gy) and 1 gray = 1 joule per kilogram, and 10/sup 8/ rads = 1 megajoule per kilogram.)

Hazardous Waste/Mixed Waste Treatment Building throughput study
The hazardous waste/mixed waste HW/MW Treatment Building (TB) is the specified treatment location for solid hazardous waste/mixed waste at SRS. This report provides throughput information on the facility based on known and projected waste generation rates. The HW/MW TB will have an annual waste input for the first four years of approximately 38,000 ft{sup 3} and have an annual treated waste output of approximately 50,000 ft{sup 3}. After the first four years of operation it will have an annual waste input of approximately 16,000 ft{sup 3} and an annual waste output of approximately 18,000 ft. There are several waste streams that cannot be accurately predicted (e.g. environmental restoration, decommissioning, and decontamination). The equipment and process area sizing for the initial four years should allow excess processing capability for these poorly defined waste streams. A treatment process description and process flow of the waste is included to aid in understanding the computations of the throughput. A description of the treated wastes is also included.
