Temperature tests of high frequency SLIFER oscillator, LEA73-2176. [For monitoring underground nuclear detonations at Nevada Test Site]
SLIFER (Short Location Indication by Frequency of Electrical Resonance) systems measure stress wave velocity in solid or liquid materials. They monitor underground nuclear detonations at the Nevada Test Site (NTS). A shorted length of coaxial cable is a component in an oscillator's tank circuit. This sensor cable is inductive when less than one-fourth wavelength long at the oscillator's resonant frequency. The stress wave from a detonation crushes and shorts this sensor cable. As the short proceeds, inductance decreases and oscillator frequency increases. Later we convert frequency vs time to shock-front position vs time. Some doubt existed about the reliable operation of the oscillators in cold weather. Therefore these tests were conducted to check their reliability under several conditions: (1) at temperatures from -40/sup 0/ to 60/sup 0/C; (2) with three sensor cable lengths; (3) with sensor cables shorted or open at the far end; and (4) at two input power voltages. Results are presented.

Missing Mass Spectra from p p ---> p X from 9-GeV/c to 300-GeV/c
Missing mass spectra were obtained by measuring recoil protons from the reaction p + p {yields} p + X in the Jacobian peak region at |t| = 0.175 and 0.25 (GeV/c){sup 2}. The incident momentum range from 9 to 300 GeV/c was covered continuously by taking data during the acceleration ramp of the Fermi National Accelerator Laboratory machine. Our missing mass range varied from 1.5 to 8.5 GeV and we observed the well known N*(1688) and N*(2l90) but no significant structures at higher mass.

Elastic and strength properties of Hanford concrete mixes at room and elevated temperatures
Objective was to determine the effects of long-term exposure to elevated temperatures on the strength and elastic properties of concrete mixes used in Hanford radioactive waste storage tanks. The report contains data from tests conducted on two Hanford concrete mixes to determine the modulus of elasticity, Poisson's Ratio, compressive strength, and splitting tensile strength at room temperature and elevated temperatures. All tests were made on 6-in. dia. by 12-in. long cylinders. Modulus of Elasticity and Poisson's Ratio were determined by sonic (dynamic) and static test methods. Variables were temperature, length of exposure to elevated temperatures, and curing time prior to exposure to elevated temperatures. 16 fig. (DLC)

Advanced fuel cell development. Progress report for January--March 1977.
Advanced fuel cell research and development activities at Argonne National Laboratory (ANL) during the period January to March 1977 is described. Efforts have been directed toward understanding and improvement of molten carbonate electrolyte fuel cells operating at temperatures near 650/sup 0/C. A primary focus of the work has been on developing electrolyte structures which have high strength and conductivity, as well as good electrolyte retention, and on developing methods of synthesis for electrolyte structures that are amenable to mass production. Several synthesis methods have been investigated, and at least one appears to yield a highly desirable product and to greatly simplify production. Cell testing is essential for understanding and evaluating individual component behavior and the interactions of the components under realistic operating conditions. Most of the testing to date has been conducted in a 2/sup 3///sub 4/-in.-dia cylindrical cell with Type 316 stainless steel housings and current collectors, a nickel anode, and a nickel oxide cathode. Reproducible cell operation has been achieved in these cells, and operational parameters have been brought under control. Necessary improvements in cell components have been defined, and a systematic program of optimization has begun. Components evaluation and development include post-test analysis and evaluation of all …

Material control assessment procedure
The material control system assessment procedure being developed by the Lawrence Livermore Laboratory for the U.S. Nuclear Regulatory Commission is reviewed. It consists of five major sections: Target Identification, Adversary Sequence and Simuli Generation, Material Control System Response Determination, Safeguard System Outcome Determination, and Safeguard System Utility Determination. When adopted, this procedure will reduce safeguards licensing problems by providing compatibility with future performance based regulations, explicit evaluation rules and requirements, well-defined trade-off structures, and user-oriented and systematic evaluation and design tools.

Hydrogen-engine performance-analysis project. Second quarterly report first year of program
The objective of this research effort is to obtain the design data-base covering performance, operational characteristics and emissions essential for making a rational decision regarding the selection and design of prototype hydrogen-fueled, air-breathing engines capable of being manufactured for general automotive use. To this end hydrogen-fueled internal combustion engines were divided into fourteen subgroups. An engine representative of each subgroup will be tested during the course of the three year program. The Project Program Plan calls for investigation of pre-intake valve closing fuel ingestion (Pre IVC) hydrogen-fueled engines during the first two years. Work accomplished during the second three months of the project is reported. Activities during the second quarter concentrated on: final apparatus debugging, engine break-in, preliminary testing to determine qualitative apparatus operating characteristics, rearranging of the proposal test schedule and performing of tests with engine 1 (carbureted, throttled, no H/sub 2/O injection, no EGR and engine 4 (carbureted, unthrottled, no H/sub 2/O injection, no EGR. The details of these activities are described.

Earthquake Resistance of Earth and Rock-Fill Dams, Report 2: Analysis of Response of Rifle Gap Dam to Project Rulison Underground Nuclear Detonation
Summary: The motion of Rifle Gap Dam was measured in September 1969 during the Project RULISON underground nuclear explosion. The observed response was then compared with the response computed in a mathematical model. Observed and computed responses were similar. From this study it appears that the mathematical models used are applicable to the design and analysis of soil structures, at least for ground motion intensities comparable to those observed at Rifle Gap Dam.
