Magnetic fusion energy annual report, July 1975--September 1976

Description: Supporting research activities continued to provide the technical basis for future mirror-confinement experiments. The industrial development of a high-current, high-field, high-current-density Nb/sub 3/Sn conductor was the main goal of the superconducting magnet program. Beam direct conversion was being developed as a means of raising the efficiency of neutral-beam production, and plasma direct conversion was shown to work as predicted. Conceptual designs were completed for various types of po… more

Materials selection of surface coatings in an advanced size reduction facility. [For decommissioned stainless steel equipment]

Description: A materials selection test program was conducted to characterize optimum interior surface coatings for an advanced size reduction facility. The equipment to be processed by this facility consists of stainless steel apparatus (e.g., glove boxes, piping, and tanks) used for the chemical recovery of plutonium. Test results showed that a primary requirement for a satisfactory coating is ease of decontamination. A closely related concern is the resistance of paint films to nitric acid - plutonium en… more

Analytical qualification of system identification (modal analysis) codes for use in the dynamic testing of nuclear power plant structures

Description: The analytical evaluation of two particular system identification codes used at Lawrence Livermore Laboratory is presented. Both codes are eigenparameter identification codes; however, one uses a time domain approach while the other a frequency domain approach. The evaluation was accomplished by analytically generating several time history signals in which the true modal parameters were known. These time histories ranged from widely spaced modes with spacing factors of 100 percent to closely sp… more

Snubber qualification and test requirements

Description: The use of snubbers for safety related piping systems has increased significantly during the last decade. A corresponding increase in snubber requirements (criteria) has also occurred. A review of these criteria indicates inconsistencies and contradictions, and reflects how rapidly knowledge and experience has been gained and applied. This study reviews and summarizes existing criteria, illustrates inconsistencies and recommends research to resolve conflicts.

Physics Design of the National High-Power Advanced Torus eXperiment

Description: Moving beyond ITER toward a demonstration power reactor (Demo) will require the integration of stable high fusion gain in steady-state, advanced methods for dissipating very high divertor heat-fluxes, and adherence to strict limits on in-vessel tritium retention. While ITER will clearly address the issue of high fusion gain, and new and planned long-pulse experiments (EAST, JT60-SA, KSTAR, SST-1) will collectively address stable steady-state high-performance operation, none of these devices wil… more

Ion Beam Deposition of (NbTa)2O5/SiO2 Multilayers for High-Efficiency Dielectric Gratings for High Average Power Laser Systems Operating at 800 nm Central Wavelength

Description: The ion beam deposition of (NbTa)2O5 has been investigated for realizing high reflectance multilayer stacks of high damage threshold for applications in the engineering of dielectric gratings for use at 800 nm. Deposition conditions were optimized to yield fully oxidized films as determined from x-ray photoelectron spectroscopy (XPS). The film properties were also investigated using spectroscopic ellipsometry, and spectrophotometry to determine their refractive index and thickness respectively.… more

Preliminary Test Results for the MICE Spectrometer Superconducting Solenoids

Description: This report describes the MICE spectrometer solenoids as built. Each magnet consists of five superconducting coils. Two coils are used to tune the beam going from or to the MICE spectrometer from the rest of the MICE cooling channel. Three spectrometer coils (two end coils and a long center coil) are used to create a uniform 4 T field (to {+-}0.3 percent) over a length of 1.0 m within a diameter of 0.3 m. The three-coil spectrometer set is connected in series. The two end coils use small power … more

Slug cocking and column bowing experiments

Description: A large number of ``hot spot`` slug failures characterized by intergranular corrosion of the aluminum can have occurred in the past year. The cause of this type of failure may be vertical displacement of one or more slugs in the slug columns. To determine if such displacement may reasonably be expected and to determine the cause and cure of the displacement a set of experiments have been performed in the 189-D laboratory. This document presents data which has been thus far collected. (1) Slugs … more
