Recording Equipment for Internal Friction Measurements

Description: An apparatus was developed for recording internal friction data in such a manner as to circumvent many of the laborious and time-consuming observations and calculations usually associated with these measurements. An optical lever is used and the passage of the beam across the scale is detected by photoconductive cells. The cells are strategically located so that, when their signals are fed through a multichannel switching circuit to the pens of an operation recorder, a plot of the logarithm of the vibrational amplitude versus the number of cycles is recorded on the chart. From the definitmon of the logarithmic decrement, ( delta ), it can be shown that the slope of this curve is - delta . The apparatus is inexpensive and requires a minimum of maintenance. It has been used for accurate determinations of values of delta from below 0.0001 up to 0.3. (auth)

EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF ULTRASONIC VIBRATIONS ON BURNOUT HEAT FLUX WITH BOILING WATER. Quarterly Technical Progress Report No. 3, April-June 1961

Description: The heat-transfer loop was completed and is in operation. Difficulty was experienced in obtaining a sufficiently strong connection between the burnout- detector voltage tap and the heating element. This problem and its potential solution are described. The lack of means of obtaining controlled burnout prevented collection of data on the burnout effects of the ultrasonic field. (auth)

CHEMICAL ENGINEERING DIVISION SUMMARY REPORT, JULY, AUGUST, SEPTEMBER, 1961

Description: Development activities are reported on pyrometallurgical processes including melt refining and those using liquid metal solvents. Development of processing facilities for EBR II is also reported. In other work, laboratory- and engineering-scale investigations on fluoride volatility processes were condueted, and conversion of UF/sub 6/ to UO/sub 2/ was studied. Investigations are also reported concerning the kinetics of metal ignition and oxidation, and metalwater reactions. In work associated with reactor chemistry, data on nuclear constants are reported and developments in thermoelectricity and reactor decontamination are described. (J.R.D.)

Research on human genetics in Iceland. Progress report

Description: Records of the Icelandic Population are being used to investigate the possible inheritance of disabilities and diseases as well as other characters and the effect of environment on man. The progress report of research covers the period 1977 to 1980. The investigation was begun in 1965 by the Genetical Committee of the University of Iceland and the materials used are demographic records from the year 1840 to present and various medical information. The records are being computerized and linked together to make them effective for use in hereditary studies.

PHYSICO-CHEMICAL STUDIES OF CLAD UO$sub 2$ IN POTENTIAL MELTDOWN ENVIRONMENTS.

Description: Behavior of zirconium alloy clad UO{sub 2} fuel elements in steam and air at 100 deg C to the melting point of UO{sub 2} was studied. Heating tests of Zircaloy-4 tubes with internal pressure show that steam oxidation of the metal results in lower deformation rates, less deformation, and higher failure temperature. Air oxidation of Zircaloy-4 is erratic and occurs at a greater rate than in steam due to the reaction with N in the air. Rate-controlling mechanism for UO{sub 2} oxidation by steam is the diffusion of O through UO{sub 2+x} lattice. The air oxidation rate of 304 stainless steel is about 10{sup 3} times less than the rate in steam up to 1370 deg C due to excess CR{sub 2}O{sub 3} film formation. During steam oxidation, the film provides less protection because of its spinel structure. Tensile strength of annealed 304 L decreased from 0.66 kg/mm{sup 2} at room temperature to 0.86 kg/mm{sup 2} at 1375 deg C. Thermal conductivity increased with temperature. The spectral emittance of Zircaloy-4 varied. Solution of O in the metal during prolonged heating caused spectral and total emittance to approach the values of the unoxidized metal. (F.S.)

SNAP Radioisotope Space Programs Quarterly Progress Report No. 9, October 1 Through December 31, 1961

Description: All Phase I and Phase II testing was completed. Both launches of Phase I were successful, neither Phase II launches were successful. Test data recovered on Phase I launchings included optical coverage of re-entry and the trajectory and weather data; no telemetry canister temperature data were obtained. No test data were obtained on Phase II experiments. Reduction of Phase I test data was begun. The Phase II (Sub-subtask 7.3.2) was terminated December 20, 1961, when no test data were recovered for comparison with the analytically predicted results. The Sub-subtask 7.3.3 program (Generator Re-entry Burnup Study) was completed and terminated December 29, 1961. The study objectives were met. The Sub-subtask 7.3.4 program (High Altitude Sampling) was terminated when it was completed November 30, 1961. All study objectives were met. Topical reports were prepared on Sub-subtasks on the work performed in the reporting period that was not included in the topical reports is included. Checkout and troubleshooting operations on the last two subroutines and main radioisotope shielding code were completed. Results from several runs of a simple check problem compared well with published data. (auth)

A SUMMARY OF INCIDENTS INVOLVING USAEC SHIPMENTS OF RADIOACTIVE MATERIAL, 1957-1961

Description: Data are summarized on incidents that have been sustained by the AEC in the transport of radioactive materials from 1957 through 1981. In the period covered by this report there were 47 incidents reported. Twenty-nine did not result in the release of radioactive materials. Of the remaining 18 cases there was none that involved any serious radiological consequences or involved costly cleanup. Six of the incidents involved onsite movements of materials. The incidents are classified in accordance with the type of radiation release that occurred, mode of transport, and type of incident. Photographs are included for a number of the incidents. (C.H.)
