Investigations of Ice-Free Sites for Aircraft Landings in East Greenland, 1959
Abstract: "Thirty-three specific landing sites were investigated in the ice-free land area of East Greenland between Scores by Sund and Loch Fyne. Eight of these are considered suitable for emergency landings in summer by heavy cargo planes, and several more for light cargo planes. Several sites were investigated for the Royal Greenland Trade Department in the Scorebysund - Kap Tobin area. A 1550-foot airstrip was located on a gravel terrace in the Jaettedal, eight miles northwest of Kap Tobin, and a short strip requiring some construction work was located near Kap Tobin. An 11,500-foot airstrip was tentatively laid out on a gravel terrace at Storelv, near Moskusoksefjord. Utilization of several of these sites can add a significant safety factor to commercial or military aircraft operations in East Greenland. Reconnaissance observations verify the presence of abundant emergency sources of fresh water in East Greenland; analyses of 36 samples indicate water of good to excellent chemical quality."
The Cumulus and Meteorological Events of the Florida Peninsula During a Particular Summertime Period: Cloud Refractive Index Studies IIIA
The cumulus cloud events of the Florida peninsula that were observed during a 19-day period of photoreconnaissance in August and September 1957 are described and illustrated. The associated meteorological and rainfall events are also described and the intercorrelations among the various observations are pointed out. The study findings revealed that the principal factors governing the cloud and rainfall situations of the different days were (1) the low-level advection of water vapor into the peninsula from the oceanic surroundings, (2) the wind transport, into the heated peninsula from the oceans during the daytime, of pre -existing cumulus populations containing appreciable liquid water, (3) the low-level convergence, and associated updraft motion, engendered by the synoptic situation and the peninsula sea breezes, and (4) the precipitable water content of the lower Florida air mass.

Geodimeter Measurement of Earth Strains on Rainier Mesa, Nevada Test Site
Abstract: "Geodimeter surveys were made on four traverses near the east scarp of Rainier Mesa between October 27, 1967 and April 26, 1968. These measurements were made in order to determine if an changes in distance between survey stations had resulted from downslope creep of the rocks behind the scarp, or if any displacements had resulted from nuclear explosions beneath the mesa and in adjacent areas. A persistent small but possibly significant, slopeward displacement was measured along one traverse and may represent detachment of a large block; monitoring for an additional period of time is recommended."

Preliminary report on Bureau of Mines Yellow Creek corehole no. 1, Rio Blanco County, Colorado
Analysis of geologic, hydrologic, and geophysical data obtained in and around Yellow Creek core hole No. 1, Rio Blanco County, Colorado, indicate a 1,615-foot section of oil shale was penetrated by the hole. Geophysical log data indicate the presence of 25 gallons per ton shale for a thickness of 500 feet may be marginal. The richest section of oil shale is indicated to be centered around a depth of 2,260 feet. Within the oil shale the interval 1,182 to 1,737 feet is indicated to be relatively structurally incompetent and probably permeable. Extension of available regional hydrologic data indicate the oil shale section is probably water bearing and may yield as much as 1,000 gallons per minute. Hydrologic testing in the hole is recommended.

Non-military Uses of Nuclear Explosions
Introduction. With the development of fission and subsequently of thermonuclear explosives, a very large source of cheap energy has become available. The problem of using this energy for peaceful purposes safely and economically presents itself as one of the most interesting and important of our time. In explosions the energy is released very suddenly. Conversion of this sudden release of energy at extremely high temperature and pressure into the form of useful work, either mechanical or chemical or thermal, must be accomplished in order for such explosions to have nonmilitary uses. The technical feasibility of such conversions in a number of different instances will be described in this article. At the same time one must be able to control nuisance effects. Examples of these are seismic effects, the blast and heat which at least in the atmosphere always accompany such explosions, and the problem of radioactivity. Even given the technical feasibility of these accomplishments, which in some cases seems quite clear from what is known already, one must prove economic feasibility. That is to say, one must show that the cost of certain nonmilitary undertakings will be considerably less by the use of nuclear explosions than by conventional methods.
Seismic Decoupling for Explosions in Spherical Cavities
Abstract. A series of paired explosions in a salt mine near Winnfield, Louisiana, has been conducted to test a theory by Dr. A. L. Latter concerning seismic decoupling by underground cavities. The theory predicted a decoupling of about 100. Free-field and surface measurements from an explosion in either a 6-ft- or a 15-ft-radius spherical cavity were compared with similar measurements from a completely tamped explosion. Shot sixes were from a 10 lb up to a few tons. Surface measurements were made out to 100 km and covered the frequency range from 0.05 to 100 cpa. The experiment confirmed that decoupling does occur. The actual decoupling factor as a function of frequency is presented and compared with the Latter theory.

Transient Thermal Stress in Tubular Reactor Elements
In this paper, a theoretical solution is developed for the transient thermal stress distribution in a reactor fuel tube of circular cross sections with spatially uniform internal power generation and forced convective heat transfer at the inner surface of the tube. Solution of the equation of heat conduction is done my means of a Laplace transform with subsequent application of the inversion integral to arrive at a final expression for the transient temperature distribution. The solution is of interest in the analysis of transients in reactors which use either a gas or liquid heat transfer medium. The work was initiated in conjunction with the quench testing of ceramic fuel elements for a gas-cooled reactor. Expressions for the component stresses are given explicitly and examples of application of these formulas to startup of a gas cooled reactor and the flow quenching of a fuel tube are given.

Tory II-A Instrumentation System : Brief Description
Abstract. The Tory II-A reactor is a small, air cooled, high power-density reactor which is to operate at quite high temperatures. Design of the reactor is essentially complete. First operation is scheduled for late 1960 at the Nevada Test Site of the Atomic Energy Commission. Since the reactor is unshielded, the control room which houses the recording and indicting equipment is located approximately two miles from the test bunker. Signals from reactor and facility transducers are amplified in the test bunker and transmitted by cable to the control point. The kinds of quantities measures include neutron flux level, temperatures, pressures, vibration amplitudes, strain and air mass flow rate. The recording and indicating system is centered around 258 channels of 1.5 cycle per second, pulse-width modulation tape recording equipment and 72 channels of 120 cps, analogue strip-chart records. In addition, there is a number of the usual meters, scalers and slow-response strip-chart recorders.
Neutron Diffusion Theory Programs and Their Application to Simple Critical Systems
Introduction. The Lawrence Radiation Laboratory of the University of California has developed a series of reactor neutronic programs for an IBM 709 Data Processing System.. This paper presents a brief outline of these codes and includes the results of one- and two-dimensional diffusion calculations used to interpret data from a series of enriched-uranium beryllium-oxide moderated critical measurements. These were performed for the specific purpose of evaluating the computer programs. The time-independent neutron diffusion theory criticality codes are 9ZOOM, a one-dimensional multigroup program; and 9ANGIE, a two-dimensional multigroup program. A series of codes, named SOPHIST, are described which prepare neutronic input data for the criticality codes. Examples of modification of the data to account for disadvantage factors, anisotropic scattering and for the (n,2n) reaction of Be9 are given. The critical assemblies include bare and graphite-reflected systems, using atomic BeO/U235 ratios from 247/1 to 7660/1, arranged in simple one- and two-dimensional rectangular parallelepiped arrays. All of the assemblies utilized heterogeneous arrangements of moderator and thin uranium foils. These systems are not truly thermal and are in a range where critical mass is extremely sensitive to size. The constants used in the multigroup (18 energy groups were used) calculations are presented in tabular form. Certain problems are used as test examples to show sensitivities to mesh spacing, extrapolation parameters and shelf-shielding factors. The results of the diffusion calculations of the critical mass are within 10% of experimental values.
Monte Carlo Schemes for Neutron Migration Using Importance Sampling and Splitting
Abstract. Monte Carlo methods using importance sampling and splitting are proposed for estimating the effectiveness of neutron shields. As usual, the aim is to increase the number of particles that go through or around the shield, this increase being compensated by a decrease in the weights of these particles. With suitable modifications, the ideas are applicable to to other Monte Carlo problems. One way of using splitting and Russian roulette is to require that the weight of each particle be approximately equal to a specified function of the coordinate; one such function is given in equation. The proposed form of importance sampling uses a cross-section for particle collisions that is the product of the neutron cross-section (or its square root) with a linear function of the cosine of the angle between the particle direction and some preferred direction. The probability density of this cosine itself is taken proportional to the reciprocal of this same linear function. This function is adjustable on both a regional and an overall basis.
State of Matter at High Pressure
Abstract. The region where exact thermodynamic description of the state of matter at high pressure and high temperature is possible is located. In the remaining region various approximate theories and empirical relations are discussed. These considerations are applied to hydrogen to locate the density and pressure at which the diatomic bond collapses. Also the approximate conditions are determined at which no bound electron states exist.
High Current Pulsed Electron Accelerator
The most important component required for the Astron experimental facility is a high energy, high current, pulsed electron accelerator. A thin cylindrical layer of high energy electrons trapped within an axially symmetric magnetic field is the key feature of the Astron thermonuclear device. The trapping magnetic field is constant in time. Therefore, it is not possible to inject electrons and trap the electrons in this field unless during the injection phase a part of the electron energy is absorbed by some friction process. This is accomplished by means of eddy currents generated on suitable passive circuits by the current of the injected electron bunch. This method has ben described elsewhere. However, in order to achieve an effective loss mechanism the current of the injected electron beam must be over one hundred amps. Such high current beams are difficult to handle except if the electron energy is high enough so that the electrostatic repulsive force is compensated to great extent by attractive magnetive forces. Hence the electron energy required is 5 Mev or higher. Other requirements on the electron layer yield the same result.
On the Establishment of a Temperature Function
Among the thermodynamic variables, which include temperature (T), energy per unit mass (E), volume per unit mass (V), pressure (p), and others any two may be selected as independent, and on this pair will depend, in principle, every other variable, each such relationship constituting an "equation of state". Thus, the common choice of V and T as independent variables implies that E is given by a function E(V,T), p by a function p(V,T), and similarly for the other variables. Occasionally, it is desirable to select V and E as independent variables rather than V and T, and to define the functions. The concern of this paper will be with the relationship between the two functions p(V,E) and T(V,E) since these have considerable utility. Two illustrative cases will be examined, namely, that of a "perfect gas" and that of a model representing a real substance.

Crystallography of Some of the Transition Element Beryllides
A crystallographic study of the transition element beryllides was undertaken in support of phase diagram work. These beryllides are very high melting, and the use of ordinary methods make it difficult to determine stoichiometry. We have succeeded in establishing the compositions and complete crystal structure description of all of the room temperature stable or metastable compounds of the beryllides of niobium, tantalum, titanium zirconium, hafnium, vanadium, chromium and molybdenum. Since some of the structures found were not previously reported, complete structure determinations had to be done.

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.
