SNAP 10A FS-3 reactor performance

Description: SNAP 10FS-3 was the first flight-qualified SNAP reactor system to be operated in a simulated space environment. Prestart-up qualification testing, automatic start-up, endurance period performance, extended operation test and reactor shutdown are described as they affected, or were affected by, overall reactor performance. Performance of the reactor control system and the diagnostic instrumentation is critically evaluted.

Design criteria for phase II dummy hydraulic core for containment systems experiment reactor simulator

Description: The design of a Phase II dummy hydraulic core for the CSE reactor simulator is described. The core will be a scale model having features typical of PWR or BWR reactor cores, and will include control rods and associated support mechanisms, fuel elements, a thermal shield, top and bottom core guide and support plates, and flow baffles. The core and simulator vessel will be instrumented to provide measurement of temperature, static and differential pressures, forces on core components, and rarefaction wave pressures during high temperature, high pressure blowdown studies.

Theoretical density of lithium aluminate updated

Description: The ''handbook'' density for LiAlO/sub 2/ is 2.55 g/cc. Recent data show that it should be revised to 2.62 g/cc. In the future densities reported as percent of theoretical should be based on 2.62 g/cc as being 100 percent. Values quoted on this basis will be more realistic. In order to avoid confusion it will be necessary to state which number percent of theoretical density are based upon--that is, ''2.62 g/cc = 100 percent,'' or ''2.55 g/cc = 100 percent.'' For the convenience of those working directly with the material, a conversion chart is included along with a table which gives density (g/cc) versus percent density based on 2.62 g/cc.

Evaluation of process variables in the cation exchange recovery of plutonium from 234-5 building sump water

Description: A previously reported cation exchange process for the recovery of Pu from sump water was studied in order to improve the procedure. The flowsheet calls for adjustment to 0.03M HNO/sub 3/, the addition of NH/sub 4/HSO/sub 3/ for Pu reduction, the addition of Al/sup 3 +/ to complex F/sup -/, followed by passage of the solution through a column of Dowex 50W, X-8 resin. Distribution coefficients were measured between the resin and synthetic sump solutions under a variety of possible simulated flowsheet conditions. By far the highest distribution coefficients were obtained with Pu(III) without the addition of Al. Results with Pu(IV) varied from borderline to unsatisfactory depending on conditions. It is concluded that the process will be satisfactory if the Al addition is eliminated. (JGB)

Characterization of commercial aluminate, silicate, and Zero-X materials

Description: Lithium aluminate and lithium silicate powders (Lithium Corporation of America) and Zero-X pellets (Ferro Corporation) have been analyzed spectrochemically, by x-ray diffraction, and for lithium, carbon, and water content. These data are presented along with some important physical constants of the materials. Aluminate and silicate powders are incompletely calcined, containing up to 3 wt percent residual lithium carbonate. They have lithium contents that are sub-stoichiometric by as much as 20 percent. They have moisture contents up to 7 wt percent. Aluminate powders contain a variable mixture of the ..cap alpha.. and ..gamma.. allotropes. Silicate powders have the single lithium meta silicate structure. Average particle size of the powders ranges from 75 to 100 microns. Zero-X pellets are calcined completely, and have stoichiometric lithium content, about 105 ppM water, and a density of 1.83 g/cc. Crystal structure is a solid solution of silica in ..beta..-Spodumene.

An Interactive, Time Share System for a Small Computer

Description: The motivation for an interactive computer system is to obtain fast response for program generation, debugging, and running. The human user retains control of the computing process, and can modify program, change parameters, and correct errors as required during solution of the problem. An interactive system contains a man-computer interface as a distinguishing characteristic. This interface is not present in the more common, batch process, computer systems.

Description and Analysis of the IBM 2741

Description: The IBM 2740 and 2741 are IBM's versions of a printer-keyboard designed primarily for point to point communication. The 2740 is the more glorious one with numerous options. The. 2741 is as simple as possible with just one major option. Neither of these units approaches the complexity or number of options available on a 1050 system.

Specifications for Multifunction Storage Unit Type I

Description: The Multifunction Storage Unit, Type I is a storage device capable of storing geometrical information in visual display form. The storage is accomplished by means of an electrostatic storage cathode ray tube. The Storage Unit consists of this storage tube and its associated circuitry. Associated circuitry is considered to be all circuitry required by the storage tube itself which is necessary to make the unit a self-contained storage unit. The following six external signals are all that is required in order to write, store and erase in the unit: vertical deflection signal, horizontal deflection signal, gate signal, z axis signal, erase signal (local or remote) and AC power. The erase signal causes the entire screen to be erased and primed for writing.

Exact Semiclassical Calculations of Translational-Vibrational Energy Transfer

Description: We present "exact" calculations, by the semiclassical method, of vibrational excitation of a harmonic diatomic molecule A-B, in its ground vibrational state, upon collinear collision with an atom C. Results are compared with those of first-order quantum mechanical time dependent perturbation methods and those of purely classical methods.

The Role of Population-Dependent Factors in Altering Adrenal Steroidogenesis and Reproduction in the Cottontail Rabbit in Ohio.

Description: Fifty-one female cottontails were collected during their first pregnancy of the breeding season in 1964. The reproductive performance of these animals has been completely evaluated and the adrenal glands incubated. Chromatographic separation and quantitation have been carried out on the majority of the adrenal incubates.

Section on Salt and Adrenals

Description: There is no evidence to suggest that the adrenal medulla plays a significant role in the production or maintenance of renal hypertension. The decisive experiment was made by Goldblatt and collaborators/who successfully produced experimental hypertension in dogs by renal artery constriction despite the surgical removal of·one entire adrenal and the medulla of the other.
