The Ferndale Earthquake of June 7, 1975, provided a unique opportunity to study the accuracy of seismic soil-structure interaction methods used in the nuclear industry because, other than this event, there have been no cases of significant earthquakes for which moderate motions of nuclear plants have been recorded. Future studies are planned which will evaluate the soil-structure interaction methodology further, using increasingly complex methods as required. The first step in this task was to perform deconvolution and soil-structure interaction analyses for the effects of the Ferndale earthquake at the Humboldt Bay Power Plant site. The deconvolution analyses of bedrock motions performed are compared as well as additional studies on analytical sensitivity.

This progress report covers the work carried out by Lamont-Doherty Geological Observatory personnel during the contract year March 1, 1977 through February 28, 1978. The purpose of this work is to increase our understanding of the seismotectonics of the Aleutian arc and to evaluate a seismic method for delineating a magma chamber.

This report discusses some of the key issues of terrorism. It also points out some of the specific measures which affect the development of information resources to meet the threat of terrorist activities.

This report describes the major themes of a Congressional Research Service Forum, "Terrorism: Information as a Tool for Control." The Forum focused on the development of resources that could keep the government informed on terrorist activity.

Lawrence Livermore Laboratory has tested and evaluated a commercially available getter pump for use with tritium in the Tokamak Fusion Test Reactor (TFTR). The pump contains Zr(84%)--Al in cartridge form with a concentric heating unit. It performed well in all tests, except for frequent heater failures.

Bronze-processed Nb/sub 3/Sn composite wire conductors exhibit changes in their superconducting parameters when strained in tension. This paper describes a detailed study of the effect of strain on critical current and an analysis by optical and SEM techniques of crack formation in the Nb/sub 3/Sn layer under strain. The effect of strain history on both reversible and irreversible changes in critical current and the roles of differential thermal contraction induced residual strains and of Nb/sub 3/Sn cracking are discussed.

A stress analysis was performed on the 2''-LS-118-AB pipe system outside containment penetration S5-D. Deadweight, thermal expansion, and seismic loads were considered. The results indicate that this piping will meet ASME Section III, Class 2 requirements provided a U-bolt (S4) is installed as indicated in this report.

As a part of this study, B and W was to develop fluid bed system design bases and parameters using any and all sources available. The design parameters used for the fluid bed boiler designs in this study were actually developed by B and W as part of their in-house AFB development program and also as a part of the subject design study. To properly carry out the assessment portion of the work it was essential to develop an understanding of the basic interrelationship of variables in order that the final comparisons would be of consistent and realistic as possible. Inputs to meet this goal were largely based on available literature, B and W experience, and engineering judgment. In some cases we also had to venture into some theoretical development work if published results appeared incomplete. The key subject areas to be covered in subsequent pages are listed: General, Fluidizing Velocity Requirements, FBC Feed Particle Size Requirements, Calculated Slip Velocities as a Function of Particle Size and Dispersed Density, Heat Transfer Equations, Heat Transfer to Horizontal Tubes in Shallow Fluidized Beds, Combustion Efficiencies, Sulfur Capture, Freeboard Performance, Distributor Plate Design, and Economic Considerations.

This LTR presents the general basic engineering facts related to an open phase fault in a three phase power system commonly referred to as a single phase condition. It describes the probable results to electrical motors and describes the LOFT system design factors which minimize the likelihood of such a fault occurring at LOFT. It recognizes that the hazard of such a fault is a realistic threat and notes the types of relays designed to provide protection. Recommendations are made to perform a detailed engineering study to determine the most advantageous protective relay design, and to implement such a design by installation of the necessary devices and controls.

The Combined Electrolysis Catalytic Exchange system was operated to experimentally determine mass transfer coefficients and to test the process controller. Values for H/sub OG/ and K/sub tilde y/a were obtained at three separate molar flow ratios (tilde L/tilde G). Replicate values of K/sub tilde y/a from additional runs agreed with initial results to within 16%. Two process controller tests were completed that demonstrated the reliability of the system hardware and the feasibility of the digital controller software. The feasibility of using a xenon flashlamp source in the uv photodissociation step of the two-photon water-hydrogen laser isotope separation (LIS) process has been demonstrated with H/sub 2/O/D/sub 2/ and D/sub 2/O/H/sub 2/ photocatalyzed exchange experiments. A nearly 10 : 1 isotopic selectivity between the photodissociation of ground state H/sub 2/O and D/sub 2/O was observed with an unfiltered xenon flashlamp source. The effectiveness of the hydrogen scavenger system was also demonstrated in these experiments. Tests continued on samples of cement and cement-plaster mixtures which were injected with tritiated water, cured, and then impregnated with catalyzed styrene monomer. After polymerization the samples were put into uncontaminated water and the tritium concentration was monitored. No significant differences were noted except in two cases when …

The report covers the PC-2, C-beam chordal average density measurement made on the loss-of-fluid test (LOFT) primary coolant system hot leg during the L1-4 nonnuclear loss-of-coolant accident (LOCA) test conducted May 3, 1977. The P-2, C-beam, or LOFT advanced densitometer, used was of the pulse height analysis/energy discrimination, or nuclear hardened type to be used for LOFT nuclear tests. The L1-4 test verified the applicability of pulse height analysis/energy discrimination techniques of the nuclear hardened gamma densitometer. Test results show that the reactor coolant fluid chordal average density can be calculated from gamma radiation source signal measured count rate data.

Silicon single crystals were implanted with 100 keV phosphorus ions to a dose of 2 x 10/sup 16/ ions/cm/sup 2/ at both room-temperature and 600/sup 0/C. They were isochronally annealed at temperatures ranging from 400/sup 0/C to 900/sup 0/C. Sheet resistivity measurements of the specimens were taken after each anneal, together with corresponding transmission electron micrographs.

The cyclone incinerator was operated throughout the quarter utilizing the new lid assembly. Burning rates averaged 35.1 kg/h. Early indications are that equipment life expectancies may also have lengthened. Efforts continue on selection of a system to dry sludges generated in the off-gas treatment system. A quality control program was started this quarter. The ash/cement matrix studies were completed. The 65/35 mixture proved to be the best for dry-cure pellets, and the 80/20 mixture produced the best wet-cured pellets. Experimental incinerator ash was successfully sintered; the final carbon content was less than 0.1 wt%.
