Chemical Technology Division, Unit Operations Section Monthly Progress Report, May 1961

Description: The experimental results on the oxidation of H from a He stream with CuO pellets were very close to the predicted behavior based on the mathematical model. Experimental measurements of uranyl sulfate loading rates on chloride equilibrated resin showed little variation with solution concentrations. A tentative flowsbeet was proposed for cost analysis of processing a Pebble Bed Reactor. A U-Zr plate was dissolved in nitrate-free Zirflex solution. An authentic TRIGA prototype was processed in engi… more

Design of production test IP-409-A-FP, pilot test of self-supported fuel elements in K size smoothbore zirconium process tubes

Description: In the Plant Improvement Program, it is proposed to retube the K-Reactors with standard size Zircaloy-2 smooth-bore process tubes and to charge self supported fuel elements starting March 15, 1964. The first step in support of this transition program is to confirm compatibility of the fuel-tube geometry and secondly to obtain fuel-tube performance information prior to full scale commitment of the K-Reactors to this design. In view of the testing of self-supported fuel which has been accomplishe… more

NPR delayed neutron fractions and decay constants

Description: This report discusses the delayed neutron characteristics of a reactor which are a function of the distribution of fissions in the various fissionable isotopes. The delayed neutron characteristics of the NPRL delayed fraction and decay constants, are presented as functions of exposure to 2000 MWD/T for both room temperature and operating temperature. It is of importance to note that the delayed neutron fraction decreases from 0.693% to 0.539% with increased exposure. Thus 22% less reactivity ch… more

In-reactor operating conditions for three charges of KSE-3 elements in the KER loops

Description: The KSE-3 element, a 1.6% enriched Zr-2 Jacketed tubular element nominally 1.74 inch O.D. by 1.05 inch I.D., was designed for irradiation in the KER loops to simulate the behavior of an N-reactor outer fuel tube. Three charges of these fuel elements have been irradiated under PT-IP-363-A: one in KER-2 to 1985 MWD/T, one KER-3 to 3555 MWD/T, and one in KER-4 to 1.195 MWD/T. This document provides the calculated powers and temperatures for each fuel element during the time it was irradiated.

The High Temperature Heat Contents and Related Thermodynamic Properties of Lanthanum, Praseodymium, Europium, Ytterbium, and Yttrium

Description: The high temperature enthalpies of five rare earths were measured from 0 to 1100 deg C using a Bunsen ice calorimeter. The enthalpy of yttrium metal was studied from 1100 to 1675 deg C using a modified high temperature vacuum Bunsen calorimeter. The data were fitted to empirical equations from which the heat of transition and fusion, the heat capacity, and the related thermodynamic quantities were calculated. These results confirmed indications from other properties that europium and ytterbium … more

Irradiation Studies of Uranium-10 W/O Molybdenum Fuel Alloy

Description: Bare and zirconium-clad uranium-10 wt% molybdenum specimens were irradiated in NaK-filled capsules in the MTR. Irradiation conditions varied to include central-core temperatures ranging from 300 to over 1200 deg F, fuel burnups ranging from 0.36 to over 3.0 total at.% and fission rates in the range of 0.35 to 1.9 x 10/sup 14/ fissions/(sec)(cm/sup 3/) of alloy. Other parameters studied included the effects of heat treatment, changes in composition, different fabrication techniques, and changes … more

The Nature of the Axioms of Relativistic Quantum Field Theory

Description: "The formulation of field theories by means of Wightman functions is studied. It is shown that, given two field theories that satisfy all the axioms, one can construct a family of Wightmsn fields with the same properties by a process of superposition of Wightman functions. The condition of unitarity is formulated without reference to asymptotic conditions, and it is proved that the Wightman fields constructed by the superposition process (starting with "unitary" fields) fail to preserve unitari… more

TASK XII ANALYTICAL REPORT--SM-1 TRANSIENT ANALYSIS BY ANALOG COMPUTER METHODS

Description: The voltage and frequency response of selected SM-1 plant system parameters to step load changes was analyzed using analog computer measurements. The analog model was that developed for analysis of the SM-2 design. The approach to the analysis, formulation of the model, and analog recordings are presented. The data will be used to prove reliability of the analog model by comparing analog data with test data to be taken at SM-1. (auth)

INTERDIFFUSION OF HELIUM AND ARGON IN SPEER MODERATOR NO. 1 GRAPHITE (A TERMINAL REPORT ON LARGE-PORE GRAPHITES--EXPERIMENTAL PHASE)

Description: An experimental investigation of the interdiffusion and forced-flow behavior of helium and argon in Speer Moderator No. 1 graphite was performed. The data were employed to determine a mutual diffusion coefficient and to verify certain superposed-flow equations. In addition, two series of experiments at high values of the forced-flow component were conducted to investigate contributions of the backdiffusion mechanism of those pores whose diameters are equal to or smaller than the mean free path … more

STRUCTURE AND USE OF ALGOL 60

Description: ALGOL 60 is a universal, algebraic, machine-independent programming language. It was designed by a group representing computer societies from many different countries. Its primary aims are: (1) simplification of program preparation, (2) simplification of program exchange, and (3) incorporation of the important programming techniques presently known. An elaboration of the concepts of ALGOL 60 is given, mostly with the help of illustrative examples. (auth)

NEUTRON LOSSES TO Pa$sup 233$ IN THE AQUEOUS HOMOGENEOUS BREEDER REACTOR

Description: Neutron losses to Pa/sup 2//sup 3//sup 3/ in the blanket of the AHBR were computed and compared for two cases: (1) concentration of Pa/sup 2//sup 3// sup 3/ is maintained uniform by continuous mixing, and (2) batches of fertile material are shifted periodically from high- to low-flux regions of blanket. It was found that, if the fertile material is cycled through three radial positions in three days, the loss of neutrons to Pa/sup 2//sup 3//sup 3/ is no more than one per cent greater than if it… more

Variations in Isotopic Content of Natural Uranium

Description: Uranium ore concentrates from seventeen world sources were compared to a standard to determine variations in isotopic content. A spread of about 0.06% in U/sup 235/ content was indicated for the concentrates analyzed. Domestic sources showed much wider variations than those from other parts of the world. (auth)

Hydromagnetic Ionizing Waves

Description: One of the techniques by which highly ionized plasmas can be generated in the laboratory makes use of strong, electromagnetically driven shock waves propagating into a cold gas. In this paper the phenomenon is analyzed as a one-dimensional single-fluid hydromagnetic problem, neglecting dissipation behind the wave.
