Metallurgy Division Quarterly Report [for] October, November, and December 1955

Description: A total of nine clad plates, containing uranium -5 w/o zirconium 1.5 w/o niobium alloy cores and clad with Zircaloy-II, were rolled in plain carbon steel jackets, heat treated, physically evaluated, and corrosion tested. All these plates were found to be within predetermined dimensional tolerance in width, thickness, length, cladding thickness, and core distribution. Improved control of wielding variables and of the length of the seal pin projecting above the end plugs resulted in the elimination of frequently observed segmented inclusions at the seal pin interfaces.

Neutron absorption lithium detector

Description: It is planned to manufacture ceramic target elements for use in N-Reactor. The potential exists for overdilution of the lithium-aluminate with aluminum powder. One method of nondestructively determining the target element type is by neutron absorption. This technique makes use of the different thermal neutron cross sections of aluminum and lithium. The target element to be tested is placed between a neutron counter and a neutron source--the neutron count with the unknown sample is then compared with that of a standard. An experiment was conducted to determine if a neutron absorption instrument could be used to identify a lithium or aluminum target element. A sketch of the test arrangement is shown. Test results are presented.

Foaming agents for removing problem liquids from gas wells

Description: The Bureau of Mines determined agents that are effective in foaming heavy brines and oil from gas wells in severe concentrations of sodium chloride, in severe concentrations of calcium chloride, or in moderate oil-brine mixtures. Dynamic tests were designed to select the more effective foaming agents. Numerous foaming agents were tested in concentrated simulated brines, in oilfield brines having varied concentrations of ions, in heavy natural brines, and in a commercial brine generally used as a reservoir pressure-balancing fluid. Several agents were detected that could perform efficiently in the field under the most severe saline conditions. Agents that promote foaming in oil-brine mixtures were also determined.

Thermo-physics technical note No. 53: thermal and hydraulic analysis of the Tower Shield Facility experiment heat rejection system

Description: The analysis of the thermal and hydraulic characteristics of the heat rejection system of the Tower Shield Facility (TSF) experiment is presented. Among the subjects discussed here in considerable detail are the convective and radiative heat rejection capability of the heat exchanger, NaK circulation around the system loop or driven by a SNAP 2 thermoelectric pump or natural circulation, and temperature distribution throughout the system both in transient and steady-state conditions.

Creep in model pillars. [Salt, trona, and potash ore]

Description: A study was made of the deformational behavior (creep) of pillars made from three quasi-plastic rock--salt, trona, and potash ore. The first phase of this study considers the design of a model pillar suitable for creep tests; in the second phase, six model pillars were prepared from salt from two sources, from trona, and from potash ore. The pillars in each group were subjected to a different but constant axial stress, and the axial strain was measured for 1,000 hours. An analysis of the data shows that in general the creep rate for these model pillars can be expressed by the relationship .epsilon = K/sub 1/ sigma/sub 0//sup n/, where .epsilon is the strain rate, sigma/sub 0/ is the applied stress, and K/sub 1/ and n are constants. For the rocks included in this test, n ranged from 2.4 to 3.3.

Thorium processing nuclear safety review

Description: A review of the nuclear safety aspects of a proposal to process about 150 to 250 tons of thorium containing about one kilogram U-233 per ton has been made. The review was made at the request of the Chemical Processing Department in whose Purex plant the thorium processing will be carried out. The review group finds that the proposed operation can be conducted with no more risk of criticality than attends the standard plutonium processing in Purex, provided the safeguards planned by the Department are carried out. The review group also has developed some suggestions by which the Chemical Processing Department could enhance its nuclear safety position in all its processing of fissionable materials. These suggestions take the form of hazards analysis procedure additions and formalization and interpretation of criteria. These suggestions are not meant to imply that present operations in CPD are unsafe, but rather that a continuation of the past trend of upgrading safety is desirable in order to cope with more complex, dynamic and potentially more hazardous future operations.

DATA SET FOR LOW-SPEED REMOTE TERMINALS

Description: Data transmission over telephone lines involves the acceptance of serialized binary data, modulation of the data to a signal suitable to the bandwidth of the telephone. channel, transmission of the signal over the line, reception at the receiving end and demodulation of the signal to reproduce the original binary data. One typical application of data communication is between a low-speed terminal and a computer. In such a case, full-duplex operation is often desirable (i,e., transmission of information on the line in both directions simultaneously). The data set described in this report operates full-duplex and provides for channelization of the telephone line for the simultaneous use of several data sets. The data set can either be coupled to leased telephone lines or acoustically coupled to any telephone.

Supplement to "Studies on the Equilibrium Temperature for the Plutonium Alpha-Beta Transformation"

Description: The cited paper presents data which establishes the equilibrium temperature for the alpha-beta transformation of Pu at 117.0 ±0.5°C. This was observed by following the electrical resistance change in thin, high purity, mixed-phase specimens as they were thermally cycled near the transformation temperature. As expected the time required for small phase changes near the equilibrium temperature was long. Data regarding the mechanisms of the alpha-beta and beta-alpha transformations or rates as a function of temperature were not presented.

The Use of Non-Linear Regression Methods for Analysing Sensitivity and Quantal Response Data

Description: A great many special methods for the statistical analysis of sensitivity or quantal response data have been developed during the past century. This paper demonstrates that many of these techniques can be considered in the light of non-linear regression methods which have been made more tolerable in recent years with the prevalence of high-speed computers.

Thermocouple Development for Project Rover

Description: Thermocouples are used for the control and diagnostic measurement of the thermal behavior of cores in the Kiwi and Nerva reactors of Project Rover. The predominant hostile environmental conditions are those of hot hydrogen, hot graphite, and intense nuclear radiation. W/W Re thermocouples, insulated by BeO and encased in Mo or Ta sheaths, seem to show the most promise. Some aspects of thermocouple development, principally shunt effects and sheath integrity, are discussed.

Failure of the Chapman-Jouguet Theory for Liquid and Solid Explosives

Description: The usual treatment of unsupported detonation, often called the Chapman-Jouguet theory, is based on four assumptions: (1) the detonation approaches a steady state, (2) the flow is laminar and one dimensional, (3) the detonation products approach a state of chemical equilibrium some distance behind the detonation front, and (4) the detonation velocity is the minimum permitted by the conservation conditions. In a recent paper Wood and Fickett (Phys. Fluids 6, 648(1963)) proposed experiments to test the validity of the Chapman-Jouguet "theory", not requiring knowledge or assumptions about the nature of the equation of state of the detonation products, by making variations of the initial state or the explosive. In this paper we report the results of experiments in which (1) the initial state was varied by using mixtures of nitromethane and another liquid made or equal molar parts of nitric acid, acetonitrile, and water, which has the same atomic composition as nitromethane, and (2) the initial state was varied by using TNT as liquid and as solid. These results show that the Chapman-Jouguet theory is violated. The calculated pressures are 15% to 20% below the measured pressures. Results of measurements using other explosives are also presented to support the conclusion that the theory fails. No explanation or alternative theory is offered.
