Photodetachment neutralization (PDN) has been proposed as a major improvement to the gas cell neutralization utilized on current neutral beam heating systems for magnetic containment fusion devices. This PDN system will use a Chemical Oxygen Iodine Laser (COIL) to produce a light beam with photons of a near optimal wavelength which can be reflected back and forth across the path of the ion beam to create the necessary high density light ''cloud'' required for the photodetachment process. In a fusion device the neutral beam goes directly into the process vacuum chamber and therefore the oxygen iodine gas mixture in the laser must be isolated by a window from the neutral beam channel without loss of too much light or leakage of miniscule quantities of laser gas. The aerodynamic windows that have traditionally been used with chemical lasers are viewed as undesirable for the fusion application where any contamination of the fusion vacuum chamber by laser gas would be a big problem. It was concluded that the technological issues were uncertain enough that a verification by designing, fabricating, and testing of a demonstration window would be required before feasibility of such a window could be considered certain.

This standard covers the material, design, analysis, application, fabrication, testing, examination, quality assurance, certification, delivery, installation and inservice inspection of safety-related hydraulic and mechanical shock suppressors (snubbers) for nuclear reactors. These devices permit thermal expansion motion of components during normal plant service, but provide restraint to dynamic loads.

Tandem mirrors control the axial variation of the plasma potential to create electrostatic plugs that improve the axial confinement of central cell ions and, in a thermal barrier tandem mirror, control the electron axial heat flow. Measurements of the spatial and temporal variations of the plasma potential are, therefore, important to the understanding of confinement in a tandem mirror. In this paper we discuss potential formation in a thermal barrier tandem mirror and examine the diagnostics and data obtained on the TMX-U device, including measurements of the thermal barrier potential profile using a diagnostic neutral beam and charged particle energy-spectroscopy. We then describe the heavy ion beam probe and other new plasma potential diagnostics that are under development for TMX-U and MFTF-B and examine problem areas where additional diagnostic development is desirable.

Report by the OTA staff development group at the Wye retreat.

Results are reported for an ongoing effort to optimize D/sup +/ beam production by the MATS-III ion source used at RTNS-II. The characteristics of the source have been determined. Particular attention was paid to the extraction geometry and plasma production. The plasma spatial and temporal uniformity has been examined. The seven aperture triode geometry has been varied to optimize neutron production. This includes beamlet steering and electrode gapping as well as aperture shaping. 4 references, 4 figures.

The Rotating Target Neutron Source (RTNS-II) facility produces 14-MeV neutrons for materials damage studies. Initial operation for irradiations, which occurred in 1979, began with a neutron source strength of 10/sup 13/ n/s utilizing one of the accelerator-based neutron sources. Details are given on improvements which have resulted in both increased neutron production and neutron source strength and improved control and monitoring. 8 references.

We discuss the possibility of extending solid state laser technology to high average power and of improving the efficiency of such lasers sufficiently to make them reasonable candidates for a number of demanding applications. A variety of new design concepts, materials, and techniques have emerged over the past decade that, collectively, suggest that the traditional technical limitations on power (a few hundred watts or less) and efficiency (less than 1%) can be removed. The core idea is configuring the laser medium in relatively thin, large-area plates, rather than using the traditional low-aspect-ratio rods or blocks. This presents a large surface area for cooling, and assures that deposited heat is relatively close to a cooled surface. It also minimizes the laser volume distorted by edge effects. The feasibility of such configurations is supported by recent developments in materials, fabrication processes, and optical pumps. Two types of lasers can, in principle, utilize this sheet-like gain configuration in such a way that phase and gain profiles are uniformly sampled and, to first order, yield high-quality (undistorted) beams. The zig-zag laser does this with a single plate, and should be capable of power levels up to several kilowatts. The disk laser is designed around …

Since the luminosity in a linear collider depends on the horizontal and vertical emittance (epsilon/sub x/, epsilon/sub y/) as 1/..sqrt..(epsilon/sub x/epsilon/sub y/) a possible method for improving the performance would be to decrease one or both of these numbers. Once this has been done in a damping ring for example, great care must be taken to avoid effective emittance growth in the remainder of the collider. Therefore an effort should be made to measure epsilon, (x and y), as accurately as possible, both during machine development and operationally. One technique used for measuring epsilon is to insert a luminescent screen in the path of the beam and measure the size of the spot of light made as the beam passes with a television camera and some associated electronics. This has advantages over sampling type techniques (such as wire scanners) because it provides full pulse to pulse two-dimensional information.

This paper reviews several areas in which corrosion problems have occurred and what can be done to help improve future performance: BWR pipe cracking, PWR steam generators, Three Mile Island-thiosulfate contamination, secondary side problems, mechanical damage (Ginna), piping and vessel cracking, turbine cracking, and bolting. The safety and operational issues involved are listed. (DLC)

The purpose is to estimate the central-cell parameters that can be reached by injection of low-energy neutral beams. The main advantages of low energy (2-keV full-energy component) over high energy (15-keV full-energy component) are the following: (1) creation of a beam-fueled, potentially confined, central-cell plasma (n approx. = 10/sup 13/ cm/sup -3/, E/sub ic/ approx. = 1 keV, T/sub ec/ approx. = 0.4 keV) without the use of cold-gas injection or ICRH heating; and (2) reduced shielding requirement against neutrals external to the plasma. The reasons for these expectations are the larger ionization cross section and plasma radius (normalized to ion gyroradius) for low-energy compared to high-energy beams.

The microscopic basis of the Interacting Boson Model for deformed nuclei is discussed. The IBM Hamiltonian is constructed microscopically in the following two steps. In the first step, the collective nucleon pairs of J = 0/sup +/ (S), 2/sup +/ (D), etc. are mapped onto the corresponding bosons. Nucleon-nucleon interactions are also mapped onto boson-boson interactions. This mapping method for deformed nuclei was proposed recently, and it turned out that this method is consistent with the Hartree-Fock-Bogoliubov + angular momentum projection calculation. Low-lying collective states primarily consist of S and D pairs. Consequently, the corresponding boson states mainly consist of s and d bosons, while there are some admixture of g-bosons. In the second step, effects of these g-bosons are included within the s-d boson space by a unitary transformation which transforms a combination of d and g bosons into a new d-boson. By minimizing the coupling between new d and g bosons with an appropriate mixing angle, one can neglect the coupling and obtain the IBM Hamiltonian with s and d bosons. It is demonstrated that the s-d Hamiltonian thus derived indeed reproduces spectra of the original s-d-g Hamiltonian.

The main objectives of this research were to make Illinois No. 6 coal liquid or soluble with inexpensive reagents (e.g., solvolysis with methanol and acids), without high pressure equipment, and to see if our soluble products would be more reactive than whole coal in liquefaction processes. These efforts are unpromising. However, efforts to make coal soluble by oxidation with nitric acid gave encouraging results. When Illinois No. 6 and Wyodak coals were allowed to stand in sunlight for 282 days, 27% of the original weight and 32% of the original carbon were lost. Concurrent experiments in the dark at 24/sup 0/C indicate that these coals are fairly stable in air in the dark; light causes most of the oxidation. The solubility properties of these aged coals will not be available before the end of this grant period. Several other minor lines of work, some very interesting, are summarized in order of decreasing significance. 1 figure, 6 tables.

The present work is an outgrowth of studies made in support of CRBR licensing, but the conclusions drawn should be generally applicable to oxide-fueled LMFBR's. The accident under consideration is a 10 cents/s unprotected TOP (transient overpower), for which a series of PLUTO2/SAS4A calculations has been performed using a higher power CRBR EOC3 fuel pin which had 275 days irradiation. The assumption was made in the licensing work that a short pin failure will occur at the axial midplane, maximizing the positive fuel motion reactivity effect, as it was felt that a less conservative assumption could not be conclusively justified. This assumption is also made in the present case.

This report covers the second quarter of activity on the project to characterize the mineral-matter liberation and the beneficiation of ultra-fine coal. So far the work has been confined to the base-case coal from the Illinois No. 6 seam. Eight other coals will be examined later in the program. The work accomplished this quarter, and described in this report, included determination of additional bulk properties of the coal, an examination of the mineral-matter and mineral associations in the coal, and the preparation and washability testing of ultra-fine, minus 44-micrometer (325-mesh) coal for liberation studies. 8 references, 8 figures, 13 tables.
