Experimental system and component performance analysis

Description: A prototype dye laser flow loop was constructed to flow test large power amplifiers in Building 169. The flow loop is designed to operate at supply pressures up to 900 psig and flow rates up to 250 GPM. During the initial startup of the flow loop experimental measurements were made to evaluate component and system performance. Three candidate dye flow loop pumps and three different pulsation dampeners were tested.

Hydroacoustic Monitoring of Downstream Migrant Salmon and Steelhead at Wells Dam in Spring 1984.

Description: The downstream migration of salmon and steelhead in spring 1984 at Wells Dam on the mid-Columbia River was monitored using hydroacoustics. The primary objective of this research was to document run timing and describe the distribution of smolts at the dam. The study occurred from April 2 to June 15, 1984. Four transducers were deployed at the bases of pier noses at Turbines 3, 5, 7, and 9 and aimed up 24/sup 0/ into the forebay. They were sampled once every hour, 24 hours per day, for 75 days. … more

Avoiding Leakage Flow-Induced Vibration by a Tube-in-Tube Slip Joint

Description: Parameters and operating conditions (a stability map) were determined for which a specific slip-joint design did not cause self-excited lateral vibration of the two cantilevered, telescoping tubes forming the joint. The joint design featured a localized annular constriction. Flowrate, modal damping, tube engagement length, and eccentric positioning were among the parameters tested. Interestingly, all self-excited vibrations could be avoided by following a simple design rule: place constrictions… more

Second Thoughts on the Mathematical Software Effort : a Perspective

Description: The mathematical software effort bridges the gap between the discovery of numerical algorithms and the consumption of numerical software. The spectrum of activities is surprisingly wide, including tasks often associated with numerical analysis, program design and testing, programming practices, language standards, documentation standards, software organization, distribution methods, and even the specification of arithmetic engines. This paper highlights the most important accomplishments in the… more

Flibe/He concept

Description: As in all fusion blankets many physics and engineering parameters influence material temperature and heat transfer to the coolant. In performing thermal-hydraulics calculations for the Flibe/He concept, the first wall was assumed to be 5 MW/m/sup 2/. The coolant is helium with a nominal pressure of 50 atmospheres. To eliminate ''pinch-point'' steam generator problems a helium inlet temperature of 275/sup 0/C was specified. Helium outlet temperature was limited to 500/sup 0/C in order to not hav… more

Shock waves, increase of entropy and loss of information

Description: We discuss, for the simplified model of a single conservation law, the concepts of genuine nonlinearity, breakdown of classical solutions, solutions in the distribution sense and their nonuniqueness, the viscosity method, finite difference methods, and the shock condition. We then discuss, for the scalar model, the compactness of solutions constructed by the viscosity and difference methods, and derive the entropy inequality for such solutions. We derive Glimm's estimate for the total variation… more

Vanadium-base alloys for fusion reactor applications

Description: Vanadium-base alloys offer potentially significant advantages over other candidate alloys as a structural material for fusion reactor first wall/blanket applications. Although the data base is more limited than that for the other leading candidate structural materials, viz., austenitic and ferritic steels, vanadium-base alloys exhibit several properties that make them particularly attractive for the fusion reactor environment. This paper presents a review of the structural material requirements… more

In situ vitrification pilot-scale radioactive test

Description: Pacific Northwest Laboratory (PNL) is developing in situ vitrification (ISV) as an in-place stabilization technique for selected liquid radioactive waste disposal sites. The process melts the wastes and surrounding soil to produce a durable glass and crystalline waste form. These ISV process development testing and evaluation studies are being conducted for the US Department of Energy. The results of an ISV pilot-scale test conducted in June of 1983 in which soils contaminated with actual radio… more

Kinetic analysis of MHD ballooning modes in tokamaks

Description: A comprehensive analysis of the stability properties of the appropriate kinetically generalized form of MHD ballooning modes together with the usual trapped-particle drift modes is presented. The calculations are fully electromagnetic and include the complete dynamics associated with compressional ion acoustic waves. Trapped-particle effects along with all forms of collisionless dissipation are taken into account without approximations. The influence of collisions is estimated with a model Kroo… more

Magnetism and Superconductivity in Eu(Ho)Mo/sub 6/S/sub 8/

Description: A variety of ambient and high pressure experimental results reveal the interplay between magnetism and superconductivity in Ho doped samples of the pressure induced superconductor, EuMo/sub 6/S/sub 8/. Ho concentrations up to 50 atomic percent of the rare earth ions were used. High resolution magnetic measurements are consistent with the crystalline electric field ground state for the Ho/sup 3 +/ ions being a magnetic doublet consisting largely of J/sub z/ = 18. The results of high pressure mag… more

First order leveling: Pleasant Bayou geothermal test site, Brazoria County, Texas

Description: First order leveling to be conducted as part of an environmental monitoring program for a geopressured test well was reported. 39.43 kilometers of first order levels were run to NGS specifications. Twelve Class B type bench marks were set to NGS specifications. The adjusted elevation of bench mark C-1209 was used as a starting elevation and is based on a supplementary adjustment of April 6, 1979 by NGS. The closure for the loop around the well site is -0.65 millimeters. The distance around the … more

Consolidation of simulated nuclear metallic waste by vacuum coreless induction melting.

Description: Vacuum coreless induction melting with bottom pouring has exceeded expectations for simplicity, reliability, and versatility when melting the zirconium and iron eutectic alloy. The melting tests have established that: the eutectic mixture of oxidized Zircaloy 4 hulls mixed with Type 316 stainless steel hulls can be melted at 41 kg/h at 40 kW with a power consumption of 1.03 kWh/kg and a melting temperature of 1260/sup 0/C; the life of a graphite crucible can be expected to be longer by a factor… more

Geothermal feasibility study for Idaho State School and Hospital, Nampa, Idaho

Description: Apparently it is possible to obtain a geothermal source of water at about 3000 ft depth that should produce 500+ GPM at 160{sup 0}F. The present steam and condensate lines are poorly insulated which adds to the heating costs and, in addition, the condensate lines are in poor condition. If this system is retained, it will cost upwards of $100,000 to replace these condensate lines. This cost should be considered as an off-set against the cost of the geothermal system. This was not included in the… more

College of Idaho Geothermal System, Caldwell, Idaho

Description: There appears to be a good potential for a 160{sup 0}F resource at the College of Idaho site. Both existing well data and recent geologic and hydrologic investigations suggest that such a temperature should be available at a depth of approximately 3500 feet. Use of a temperature in the 160{sup 0}F range would not permit a 100% displacement of present natural gas use for space and domestic hot water. Because these systems were typically designed for 200{sup 0}F water or low pressure steam (appro… more

Doubled-ended breaks in reactor primary piping. [Guillotine breaks]

Description: Results indicate that the probability of double-ended guillotine break (DEGB) in the reactor coolant loop piping of Westinghouse and Combustion Engineering plants is extremely low. It is recommended that the NRC seriously consider eliminating DEGB as a design basis event for reactor coolant loop piping in Westinghouse plants. Pipe whip restraints on reactor coolant loop piping could then be excluded or removed, and the requirement to design supports to withstand asymmetric blowdown loads could … more
