Power level history of single-pass Richland reactors

Description: This report provides a history of the power level at which single pass reactors at the Hanford facility operated over the period Jan 1945 to Jan 1973. The reactors listed are B, C, D, DR, F, H, KE, KW, and N. A set of notes attached explain how power levels were changed, often above original nameplate power ratings, by design or regulatory changes.

Geothermal gas sampling methods

Description: A method for geothermal gas collection for chemical and isotopic gas analysis is described. The CO/sub 2/ and H/sub 2/S are absorbed in a NaOH solution and the residual gas collected in a bottle. The method can be used for sampling gases from hot springs, fumaroles, steam wells, hot water wells, etc. (WHK)

Baseline gas turbine development program. First quarterly progress report, January 31, 1973

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine-powered automobile which meets the 1976 Federal Emission Standards and which is competitive in fuel economy, performance, reliability, and potential manufacturing cost with the conventional piston engine-powered, standard size American automobile. Procurement and assembly of parts for seven engines plus spares is basically on schedule, although some areas are requiring intensive follow-up. A partial engine (in… more

Hazards review for electrolytic dissolver installation, Hood 3, 236-Z Building

Description: A comparison of the hazards involved in the existing process and the electrolytic process for dissolving plutonium metal shows that, in the opinion of the review team, no net increase in hazards will occur by operating the electrolytic dissolvers. This new process eliminates several hazardous operations such as metal burning and PuO/sub 2/ powder handling, and reduces operator time and, therefore, exposure. The new facility can be operated safely provided that the recommendations given previous… more

Extrude Hone deburring with X-base media

Description: Small precision mechanisms must have burr-free, sharp-edged parts to operate well. Controlling the size of burrs can lower burr removal costs and improve edge repeatability. Study results indicated that with conventional tooling approaches, Extrude Hone deburring with x-base media removes more material from the hole than desired and is less repeatable than required on precision miniature parts. With this media, the process is most applicable to precision miniature parts with burrs less than 25.… more

Numerical model for two-dimensional hydrodynamics and energy transport. [VECTRA code]

Description: The theoretical basis and computational procedure of the VECTRA computer program are presented. VECTRA (Vorticity-Energy Code for TRansport Analysis) is designed for applying numerical simulation to a broad range of intake/discharge flows in conjunction with power plant hydrological evaluation. The code computational procedure is based on finite-difference approximation of the vorticity-stream function partial differential equations which govern steady flow momentum transport of two-dimensional… more

Choice of working fluid and operating conditions for energy conversion with geothermal heat sources

Description: A study of electric power generating cycles which can be used in conjunction with a low-temperature geothermal energy (sensible heat) source is presented. Investigators at Los Alamos Scientific Laboratory have proposed a steam/isobutane dual cycle capable of generating 50.7 Mw of electric power. This cycle is optimized using regenerative feed water heating to yield a power output of 52.1 Mw or an improvement of 2.8%. Other power cycle designs and working fluids are investigated. Working fluids … more

Baseline Gas Turbine Development Program Fourth Quarterly Progress Report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Reasonably firm delivery schedules were arranged for all of the critical Task 1 engine parts. However, the program will likely have to continu… more

ANISN-L, a CDC-7600 code which solves the one-dimensional, multigroup, time dependent transport equation by the method of discrete ordinates

Description: The code ANISN-L solves the one-dimensional, multigroup, time-independent Boltzmann transport equation by the method of discrete ordinates. In problems involving a fissionable system, it can calculate the system multiplication or alpha. In such cases, it is also capable of determining isotopic concentrations, radii, zone widths, or buckling in order to achieve a given multiplication or alpha. The code may also calculate fluxes caused by a specified fixed source. Neutron, gamma, and coupled neut… more

Effect of a bridge balance network on a semiconductor pressure transducer

Description: Pressure transducers and accelerometers that make use of semiconductors strain gages or have strain gages diffused on a silicon diaphragm cannot be used with a bridge balance network if one wants to achieve thermal zero compensation. Thermal zero compensation is compensating for the change in output due to temperature only, and is typically +-1.5 percent of the full scale output for a temperature change of 100/sup 0/F. The reason for not using a balance network is the way in which the transduce… more

Parameter studies on the effect of pulse shape on the dynamic plastic deformation of a hexagon

Description: Results of a parameter study on the dynamic plastic response of a hexagonal subassembly duct subjected to an internal pressure pulse of arbitrary shape are presented. Plastic distortion of the cross section and large-deformation geometric effects that result in redistribution of the internal forces between bending and membrane stresses in the hexagon wall are included in the analytical model. Correlation procedures are established for relating permanent plastic deformation to simple properties … more
