Research on this grant is devoted to the calculation of heavy particle collision cross sections needed for diagnostic studies of magnetic fusion plasmas. This work requires the development and testing of new theoretical methods, with the implementation of benchmarked techniques to collisions pertinent to fusion reactors. Within the last context, we have provided charge-exchange-recombination cross sections to specific n,1-levels for diagnostic studies on TFTR and for a major compilation for IAEA. We have also completed a cross section study related to the planned neutral beam current drive for ITER. In addition, calculations were completed to assess the use of He neutral atom angular scattering measurements for JT-60. Also, new theoretical methods have been developed to more accurately calculate cross sections involving either He or H{sub 2} targets and partially stripped multiply-charged ions.

Table A shows the steady state situation. One ofthe two dewars would be supplying purge gas at (a maximum of) 20 scfm, which would leak: into the room through the welding orifice. Instantaneous uniform diffusion and exhaust are assumed. Note the probability is 1 for the 20 scfm leak since it is a planned occurrence. Table B is the same situation in the event of a power failure, estimated for twice a year (2.29 x 10{sup -4} fails/hour). This assumes that the exhaust is shut down, and the dewars are not turned off. This would require the minimum exhaust to be the same as the leak: (as an approximation). These results, however, would only be valid for an infinite supply of the purge gas, and for an exceedingly long power failure. Since the supply of LAr would only last a day at most, and the power failure would not last for weeks, this result has no real significance. In fact, the time constant for the ODH equation in this case is 5717 minutes, which means it would take 20 days for all the oxygen to be displaced. A worst case scenario would be a full dewar completely emptying into the …

It was decided to use a hydraulic cylinder resting on the floor of the argon spill trough in the EC carriage to drive the EC's motion on the center beam. Space was limited due to the spill bellows and their required support and containment system. The 0.0. of the cylinder had to be limited to 3 to 3-1/2 inches, maximum. The weight of a wet EC and carriage is estimated to be 320 tons. The rolling coefficient of friction of the Tychoway rollers chosen to guide the EC and carriage along the hardened centerbeam ways is claimed to be less than 0.0025. The driver will also need to overcome the forces produced by moving (rotating) the numerous bayonets located at the top of the cryostats in the many piping systems. These forces were conservatively estimated at 1000 lbs. The drive force required to overcome these forces was then calculated to be: 320(2,000) x 0.0025 + 1,000 = 2.600 lbs. (min. required). Due to the uncertainty in the actual roller coefficient of friction and the various unknowns in estimating the resistive forces contained in the piping and cabling systems attached to the cryostat, a conservative design factor of 5 was chosen. …

A preliminary measurement of the properties of W and Z production along with accompanying jets has been made in {anti p}p collisions at 1.8 TeV using the CDF detector at Fermilab. Distributions of jet multiplicity, and boson E{sub T}, with and without selection on jet multiplicity, were obtained. Agreement was found with perturbative QCD predictions.

The overall objective of the Full-Scale Low-NOx Cell (LNC) Burner Retrofit project is to demonstrate the cost-effective reduction of NOx generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: at least 50% NOx reduction over standard two-nozzle cell burners, without degradation of boiler performance or life; acquire and evaluate emission and boiler performance data before and after the retrofit to determine NOx reduction and impact on overall boiler performance; and demonstrate that the LNC burner retrofits are the most cost-effective alternative to emerging, or commercially- available NOx control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NOx reduction capabilities without adversely impacting plant performance, operation and maintenance.

With the end of the Cold War and of a period during which foreign assistance was motivated frequently by East-West security and political considerations, a debate has emerged over setting a new foreign aid rationale. The debate has included calls advocating a much more direct use of America foreign assistance to support U.S. commercial interests, especially for programs administered by the Agency for International Development (AID). Proponents assert that the active promotion of the U.S. trade position should be one of the top U.S. foreign policy interests and, therefore, the foreign aid program should be used on behalf of that purpose. They argue that the United States should increase assistance in the form of capital projects that can provide opportunities for American exporters, reduce cash transfer aid that in some cases is spent on non-U.S. products, and strengthen "Buy America" provisions in foreign aid laws.

This engineering note is a summary of test information and conclusions from the thermal expansion tests conducted at D-O during the fall of 1992. Each test was conducted separately but using the same basic procedure and equipment. While information on material properties at room temperature and above for these products is quite well doccumented, the companies producing these products had no available data about the thermal properties of these materials at cryogenic temperatures. This lack of readily available information prompted these tests to determine the accuracy of using the elevated temperature data for lower temperatures also. The results of each test were written up separately as stand alone short reports for immediate use in the design stages of the V.L.P.C. cryostat cassette. Both short reports are gathered here for convenient reference.

There has been significant discussion in consideration of a high resolution mass separator followed by a RFQ and a linear accelerator as the basic format for IsoSpin Laboratory. There exists another strong possibility-namely a low-resolution mass separator coupled to a cyclotron. The major objection to this approach has been that the conversion from the +1 mass separator beam to a q/m beam of 1/4 to 1/3 is thought to be highly inefficient. Since we are in the fortunate position of having the two expensive components of this system available for tests (an on-line mass separator and an ECR source), we intend to couple these devices to actually measure these efficiencies and to test ideas for improving the efficiency. We present some specifics of this approach.

By June 3, 1994, President Clinton must determine whether or not to recommend to Congress a one-year extension of his Jackson-Vanik waiver authority, in effect extending most-favored-nation (MFN)[1] trading status to China for anothe year. The media are reporting that the President has not yet decided whether he will ask for an extension, and that he may also be deliberating over whether or not to attach conditions to a recommendation for approval.

The operating limits for radionuclides in sanitary and industrial wastes were determined for a proposed landfill at the Paducah Gaseous Diffusion Plant (PGDP), Kentucky. These limits, which may be very small but nonzero, are not mandated by law or regulation but are needed for rational operation. The approach was based on analyses of the potential contamination of groundwater at the plant boundary and the potential exposure to radioactivity of an intruder at the landfill after closure. The groundwater analysis includes (1) a source model describing the disposal of waste and the release of radionuclides from waste to the groundwater, (2) site-specific groundwater flow and contaminant transport calculations, and (3) calculations of operating limits from the dose limit and conversion factors. The intruder analysis includes pathways through ingestion of contaminated vegetables and soil, external exposure to contaminated soil, and inhalation of suspended activity from contaminated soil particles. In both analyses, a limit on annual effective dose equivalent of 4 mrem (0.04 mSv) was adopted. The intended application of the results is to refine the radiological monitoring standards employed by the PGDP Health Physics personnel to determine what constitutes radioactive wastes, with concurrence of the Commonwealth of Kentucky.

Plant startup provisions, environmental considerations and control monitoring, and safety considerations are also addressed for …

The authors report on {sup 170}Yb Moessbauer spectroscopy data in the cubic fcc alloy YbPtBi, in the temperature range 0.06--30 K. The zero field spectra show a two component structure above 1.5 K, which can be analyzed as due to 85% of Yb{sup 3+} ions at a site with cubic symmetry and 15% at a site with non-cubic symmetry. Below 0.3 K, the spectra are resolved and can also be interpreted in terms of two sites, but with a dominant non-cubic site ({approximately} 60%) with Yb ions bearing small magnetic moments. The spectra with a large applied magnetic field give information on the Yb{sup 3+} C.E.F. level scheme and on the exchange interaction. The relation of the Moessbauer data with the results of {micro}SR measurements is discussed.

The goal of this program is the construction of an X-ray laser in the multi-kilovolt regime which can serve as a vital enabling technology in the broad and fundamental field of materials science. Experimental findings indicate that an entirely new technique for amplification at X-ray wavelengths is feasible. This method involves the combination of (a) a recently discovered mode of multiphoton coupling to molecules which efficiently yields core excited ions, (b) a new channeled mode of propagation for spatial organization, and (c) an ultrahigh brightness subpicosecond laser technology. The concept of molecular X-ray laser design, which involves matching the conditions of excitation to the molecular structure, enables the inner-shell excitation to be selectively achieved. Basically, the molecular approach enables the copious generation of a highly excited species to occur rapidly in an environment characteristic of dense cold matter, a situation exceptionally conducive to X-ray amplification. High energy efficiency and wavelength tunability also appear as intrinsic features of this method. Experimental data concerning the study of five cases [Xe(N), Xe(M), Xe(L), Kr(M), and Kr(L)], spanning-spectrally from {approximately} 80 eV to {approximately} 5 keV, have (1) established the important role of cluster formation, (2) verified the scaling of this phenomenon into the …
