Irradiation of an Aluminum Alloy-Clad Ceramic Pellet-Fueled Plate
From Introduction: "An experiment, designated MTR-W10, was designed to determine the effects of high burnup on the cladding and fuel of an aluminum-1% nickel alloy (M-388)-clad ceramic pellet-fuelded plate if the type manufactured at Argonne for the BORAX-IV core. Conditions of irradiation were selected to allow local boiling at the high flux end of the plate at a pressure of 600 psig."

Nuclear Characteristics of Cylindrical Breeder Reactors Containing Thorium in Pellet Form
The results of nuclear calculations for aqueous homogeneous reactors containing blanket thorium in pellet form are presented. Critical core fuel concentrations, gross breeding ratios, power densities, and multiplication as dependent on core fuel concentration and neutron balances are included. Critical U/sup 233/ core concentration for a 24in.-diam. core was 8.4 gm/l when U/Th was 0.003 in the blanket and the relative power density at the core wall was 1.04 kw/ l/Mw. A 48-in.-diam. core required 1.6 g U/sup 233//l in the core and the relative power density at the core wall was 0.095 kw/l/Mw. The reactors had gross breeding ratios of 1.12 and 1.09, respectively.

Optics of High-Energy Beams
Many of the experiments now being conducted on high-energy accelerators requires the use of beams of charged secondary particles. It is worth while at this time to attempt to summarize information about some of the most useful methods of setting up such beams. We are not concerned here with the primary beam of the accelerator. Rather, they assume that a target is struck by the primary beam and that it is desired to form a beam from the secondary charged particles that emerge from collisions within the target. The simplest system of forming this beam of secondary particles involves the use of magnetic fields only. In most cases it is desirable to obtain a beam of particles of known magnetic rigidity, or momentum. The bulk of this article is addressed to this problem. Some comments are also made about the use of electric fields in conjunction with magnetic fields. The inclusion of electric fields allows the separation of a beam of known momentum into its various components according to the velocities of the particles, hence according to the masses of the particles. These are referred to as ''separated beams''.

Preliminary Operational Safety Report for the Task 5.6 Thermoelectric Generator
The operational hazards associated with the use of a plutonium-fueled thermoelectric generator in a terrestrial satellite are evaluated. It appears that the plutonium fuel can be consumed and dispersed at high altitude during reentry, following a successful mission. As an alternative, however, since the fuel (Pu/sup 238/) is an alpha emitter with a long half life, it appears that random intant recntry following a suceessful mission is feasible. As a precaution against aborted missions, the launch azimuth should be over water as much as possible to avoid impact or dispersion in areas of signifieant population density. It is recommended that the fuel and generators be transported by air carrier to preclude local restrictions of ground transport and to provide better statistical safety. The transport phase poses a very minor safety problem. (auth)

Project Hobo : Shear and Compressional Velocity Measurements
Abstract. Three groups of 100 foot holes were drilled vertically downward from the floor of U 12e main tunnel and U 123.03 drift at the Nevada Test Site. Distances between holes in each group varied from 13 to 375 feet. One hole in each group was used a a 'shot hole'; the others for seismometers to records the energy generated in the 'shot hole'. Two types of recordings were made. One for dilatational or longitudinal "P" waves and one for transverse or shear "S" waves. Simultaneous recordings were made on photographic paper and on magnetic belts with a minimum of three "specimen" records at each hole, for each type of recording. The magnetic belts were transcribed to 1/2 inch IRIG tape for computer use. Rock density measurements were also made in the holes. From these data Poisson's Ratio, Bulk Modulus, Rigidity Modulus, and Young's Modulus were computed. Elastic constant values obtained 'in sltu' are much higher than those determined by soils laboratory tests on small rock samples. The data obtained are considered to be of exceptionally high accuracy.

QUANTITATIVE CORRELATION OF IRRADIATION GROWTH WITH PREFERRED ORIENTATION IN URANIUM
A review is presented of the methods developed at the Savansah River Laboratory and elsewhere for quantitative correlation of irradiation growth with preferred orientation inuranium, with preferred orientation characterized by x- nay and dilatometric techniques. In an application of the methods, it is shown that a strongly oriented uranium plate, clud in aluminum, was much more stable in dimen- . sions than would be expected from the observed dimensional behavior of either unrestrained single crystals of uranium or aluruinum-clad polycrystalline rod. The greater stability of the plate is attributed to a relatively strong claiding and other restraing effects. (auth)

Radium and Mesothorium Poisoning and Dosimetry and Instrumentation Techniques in Applied Radioactivity
"The study of the toxicity of Ra and MsTh(Ra/sup 228/) in humans was continued. Several Thorotrast cases were also examined. Physical and clinical studies were made on 151 persons. In all cases possible gamma ray measurements were made of Ra and MsTh decay products retained in the body, alpha -ray measurements of Rn and Rn/sup 220/ in breath, a complete medical history was taken, a complete x-ray examination was made of the skeleton, and urinalysis, hematological, and blood chemistry studies were made."

Rasium and Mesothorium Poisioning and Dosimetry and Instrumentation Techniques in Applied Radioactivity. Annual Progress Report
The study of the toxicity of Ra and MsTh(Ra/sup 228/) in humans was continued. Several Thorotrast cases were also examined. Physical and clinical studies were made on 151 persons. In all cases possible gamma ray measurements were made of Ra and MsTh decay products retained in the body, alpha -ray measurements of Rn and Rn/sup 220/ in breath, a complete medical history was taken, a complete x-ray examination was made of the skeleton, and urinalysis, hematological, and blood chemistry studies were made. Medical data are appended. An extensive intercomparison of Ra burden measurements on living subjects was carried out between M.I.T. and ANL. Results are tabulated. Complete measurements were made of tooth and bone MsTh/Ra ratios on 24 individuals. Comparison of results with data on Ra/Ca ratios of teeth and total skeleton and with data from whole-body measurements on the same individuals led to the conclusion that estimates of total skeleton Ra burden can be made with reasonable accurateness on the basis of data obtained from Ra gamma -counting a single tooth. Data are being recorded on punched cards for correlation with the incidence of various affects such as tumors, bone fractures, age at exposure, age at occurrence of effects, …

Scale "Up or Down" Analysis for Prototype Test
Introduction: In conjunction with the final design and development of a 70 MW sodium intermediate heat exchanger and a sodium steam generator, an analysis is required which can be used as a basis for a determination to scale up or scale down the designs. Included in this analysis are those considerations leading to the recommendation of the best prototype test unit and to some of the limits imposed on scaling up or down when considering future applications of designs other than those actually tested. In addition, these considerations include aspects required to accurately predict the performance, operation, mechanical reliability, and feasibility of fabrication of the 70 MW design.

SERVOMECHANISMS WITH FORCE FEEDBACK
A class of linear proportional servomechanisms is examined in which an electrical signal proportional to output force is used to improve performance. The effect of this "force feedback" on a positional servomechanism is analyzed as well as the effect on a special type of servomechanism which reflects load forces back to the input. This latter type of servomechanism is called "force reflecting." Laboratory models of these servormechanisms were designed and constructed, and experimental data are presented in support of the analysis. (auth)
