TECHNIQUES FOR ANALYZING NONSTATIONARY VIBRATION DATA

Description: Methods are described and discussed, from a general viewpoint, for analyzing data on non-stationary vibrations. The analysis must take into account both frequency and time as variables, so the methods used are complex and voluminous. The case is also considered in which the vibrations are non- stationary but repetitive. The application of the methods discussed in analysis of missile-vibration problems is outlined. (T.F.H.)

THE RECOVERY OF MECHANICALLY ENTRAPPED PLUTONIUM FROM CASTING SKULLS AND TURNINGS

Description: The small critical mass of plutonium which limits charge size, coupled with its value necessithting quantitative recovery from all residues, makes the direct recovery of mechanically entrapped plutonium from casting skulls and oxidized turnings an economic necessity. The newest method used at the Los Alamos Scientific Laboratory for the direct recovery of entrapped plutonium involves mechanical stirring and vibration of the plutonium melt to physically break up to spongy skull and oxide film, t… more

The Crosscorrelation Method of Measuring System Dynamic Response

Description: The basic relations of the crosscorrelation method are presented; and variations of the method for dealing with practical cases for which the idealized relations are inaccurate due to finite experiment length, finite bandwidth of the input signal, and uncorrelated noise in the system response signal are discussed and demonstrated.

Shield Small Source Experiments. Summary Report

Description: A shielding experiment was performed that provided a proof test of the shield calculation methods used in the MCR shield desing and provides a partial confirmation of cross-section data. Measurements were made with a gamma spectrometer behind a configuration consisting of a layer of gamma shielding material followed by a neutron shield, with the configuration exposed to neutrons from a Po --Be source. The test configuration is illustrated. Secondary gamma rays produced in the assembly were meas… more

Flow Controller Evaluation for Sodium Service

Description: Tests were conducted to evaluate the performance of a 10-in. flow controller in sodium at temperatures up to 1200 deg F. Torque tube reliability was determined by extensive mechanical cycling tests and further checking with a helium mass-spectrometer leak detector. Flow control performance and valve vibration characteristics were tested and evaluated and flow rate limits were established. The valve assembly was subjected to a thermal shock test program simulated to represent the most severe con… more

An Evaluation of the Substitution of Zircaloy for Stainless Steel in n.s. Savannah Fuel-Element Containers. Summary Report

Description: The possibility of reducing fuel-cycle costs for the N.S. SAVANNAH by replacing the stainless steel fuelelement containers in the permanent reactor core structure by similar containers of a zirconium alloy was investigated. These containers, although not integral parts of the fuel-bearing components, are located within the active core and divide the core into 32 separate channels into which the fuel elements are placed. Areas of investigation included reactor physics, fuel-cycle economics, mate… more

CRITICAL EXPERIMENT WITH BORAX-V. Internal Superheater

Description: A critical experiment was performed with 12 BORAX-V superheater subassemblies in a central voidable region plus 1228 to 1525 UO/sub 2/ fuel pins (3 wt% enriched) in a peripheral region. Removing water (28% of superheater volume) at room temperature decreased reactivity by 2.2%. The midplane (two- dimensional) peak-to-average power distribution in the voided superheater was approximately 1.24, mostly attributable to flux depressions within insulated fuel boxes. Cadmium ratios are also reported. … more

Physical Limitations on the Measurement of Transient Fields in Air and in Dissipative Media Using Electric and Magnetic Probes

Description: The properties of electric and magnetic probes for the measurement of transient electromagnetic fields in air and in dissipative media are discussed briefly, It is shown that the effective height of an electrically small loop is independent of the ambient medium. This is also virtually true for a thin electrically short dipole (or monopole). If the open-circuit voltage of a magnetic probe can be measured accurately, it is possible (in principle) to reconstruct the time history of the incident m… more

MOUND LABORATORY PROGRESS REPORT FOR NOVEMBER, 1963

Description: As a part of the effort to establish the vapor pressure of /sup 3/He as the international temperature scale between 0.3 and 3.2 deg K, the manometric contections from /sup 4/He to /sup 3/He are being determined. The results of a single run did not agree with the predicted values. Calculations indicated that a two to one thermal diffusion column cascade is more efficient than a three to one cascade for separation of neon isotopes. Gaseous impurities in neon were reduced from 3.40 to 0.26% by pas… more
