The solution of the monoenergetic Boltzmann equation in an infinite homogeneous, nonmultiplying medium with linearly anisotropic scattering and an isotropic plane source is given and compared with the corresponding solution for isotropic scattering. The effective source strength for the asymptotic flux turns out to be the same as that for isotropic scattering to first order in Σa/Σ.

The purpose of this document is to describe the design and construction of a full-scale, electrically-heated model of a 19-rod PRTR fuel element for use in heat transfer experiments.

At the present time, high-radioactivity-level wastes at Hanford are neutralized and stored as liquid in underground tanks lined with mild steel. This method of storage is relatively inexpensive and is satisfactory on a short-term basis. However, on a long term basis, liquid storage is less desirable than solid storage because of the greater mobility of the liquid. In addition, storage as aa solid would significantly reduce the volume of waste stored. Consequently, various research and development studies have been undertaken in an attempt to develop a practical waste solidification.

Investigation of aqueous and steam corrosion at elevated temperature has been carried on at Hanford for several tears. A number of reports have been published on various phases of the corrosion program but, except for monthly reports, little has been written on the progress of the Corrosion and Coatings Operation alloy development program. This interim report will outline the more important current phases of the aluminum alloy program.

In the continuing search for better methods of effecting the secondary fusion welded closure in Alsi bonded aluminum clad uranium metal fuel element, an article on "The Twin-Argon Welding Process" by J. A. Donellon was recently found in the September 1954 issue if the British Welding Journal. From a review of the article, the process appeared to have enough possibilities to warrant exploring it. Communication were established with the General Electric Company, Ltd..

The Biology Operation, Hanford Laboratories, required plutonium dioxide particles in five different micron and sub-micron size ranges. These were to be supplied as a water suspension in small containers. It was necessary to design equipment, suitable for hood operation, which would give a satisfactory separation of these particles.

In the last two or three years there has been a notable improvement in the knowledge and understanding of reactor lattice physics. During this interval, measurements of parameters have been improved and the methods of analysis have been greatly strengthened. It has become apparent that the classical ways for computing the lattice parameters are not sufficient. It is the purpose of this report to publish under one cover as much of the most recent information as possible.

Certain aspects of mating behavior in two different types of Drosophila melanogaster females (Basc and Bv) and wildtype males (Samarkand) have been investigated and compared.

The pion-pion interaction is of great theoretical importance and must be understood before the other and more familiar interactions can be systematically analyzed. Therefore, various experiments to verify the existence of a P resonance in the w w system are proposed.

Introduction. High voltage silicon mass transistors have the ability to perform circuit functions similar to the gas thyratron tube. Upon being triggered the transistor junction breaks down, or "avalanches", and can conduct a large current for a short time. The rise time of the avalanche breakdown pulse can be short, and the delay between triggering and avalanching can be short and very consistent. This avalanche action is non-destructive if the amount of peak and average power being dissipated at the junction is limited by the circuitry.

In a previous report the adaptation of Stix's ion-cyclotron-wave-heating scheme to the mirror geometry was suggested. An experiment along these lines has been conducted for the past year by E. Chambers, using a tubular P.I.G discharge to provide the basic plasma. The Chambers experiment has been eminently successful in demonstrating the transfer of rf power along the P.I.G. (as along a co-axial conductor), and the resultant acceleration of ions. The power transfer is evident from the predominantly resistive rf impedance of the P.I.G. (1 - 10 ohms), the production of intense luminosity outside the dc P.I.G channel when the rf is turned on, and by the observation large signals with magnetic pick-up loops. The ion heating is demonstrated by direct measurement of ion current on a probe some centimeters outside the P.I.G., and by the observation of energetic charge-exchange neutrals. At the same time, the characteristic features of heating by ion-cyclotron-waves, as described by Stix, are only partly in evidence. The visible broadening of the P.I.G. channel and such fast-ion phenomena as neutral emission do seem to be maximal near the expected cyclotron resonance point. However, the rf impedance is anomalous both in magnitude and parameter dependence, and there are …

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.

In the past two years a number of process optimization studies have been made with the aid of IBM machine programs. These programs have been designed to calculate optimum power levels and optimum goal exposures so that better insight could be gained for use in resolving plant operating plans. We feel that this approach has been highly successful. In January of 1960, a new program was written for the IBM 709 to incorporate the desirable features of the previous programs and to provide additional output data. This document is a description of the new programs.

The purpose of this memorandum is to transmit revisions to the goal exposure plans of reference (1). The plans, herein, supersede the previous recommendations. Similar to the plans of reference (1), the exposures calculated from these plans are designed to maximize plant return on the basis that the only restraint on metal usage is that imposed by the economics of the plutonium production process and associated uranium cycle, as described and defined in references (2) and (3). When metal throughput is limited by ex-reactor physical capabilities to a level lower than the unrestrained requirements, exposures higher than those recommended in this document would be indicated, as explained in reference (4). In essence then, these plans represent minimum economical exposures for current production fuel types, on the basis of attempting to maximize plant returns. The adjustments recommended herein, stem solely from revised estimates of the metal performance level indices (C{sub R} values) of the various metal types.

This report presents a proposed test program to study the corrosion of aluminum-clad fuel elements under conditions expected at the more severe conditions which will be encountered in operating the present Hanford reactor at higher power levels.

The objective of this test is to evaluate the hypothesis that autoclave film damage is a necessary condition for groove pitting of X-8001 alloy fuel cladding.

It is necessary to provide the option of using either aluminum or zirconium tubes in the C pile 20-tube overbore test. A bumper-type fuel element has been designed to fit a fixed ribbed aluminum tube size; zirconium tube dimensions were then determined which will provide the same flow and pressure drop when the fuel element is changed from bumper type or self-supported without changing other fuel dimensions.

Although a fuel reactor job procedure has not yet been prepared, techniques and equipment used in a current production test are adequate with minor modifications for full reactor Parker fitting reaming. With existing reactor hardware, available flow increases at B, D, and F Reactors would be limited to about 2,500 gpm. The extent of additional rear face piping problems which may be encountered as a result of reaming cannot in several instances be predicted with confidence at this time. It is expected that preliminary answers to currently foreseen problems will be available by April 1, 1961. To some extent, however, this is dependent on production tests under way or proposed, and will require coordination with various Manufacturing Operations. For vibration and flow problems in the downcomer approach piping, conclusive answers may not be available before July, 196l, although there is no positive evidence that the flow increases cannot be absorbed. Increased pressurization of effluent line junction boxes at 105-D has been solved by improved box venting. Increased flows resulting from reaming may require still greater venting capacity, which would be available for capital expenditures on the order of $3,000--$5,000 per area.

The data consists of out and inlet temperatures, and panellit and header pressures, sorted according to date and tube-pile.

This report describes efforts to develop a safe, practical method to extinguish fires inside contaminated gloveboxes. Oil, trash, and metal fires were set to test various materials and techniques. Dry chemical extinguishers and MgO sand proved more practical than flooding the boxes with either CO/sub 2/ or argon. Gas replacement techniques pressurized the boxes and greatly increased the risk of outside contamination. 5 figs. (TEM)
