Radiometallury examination of three overbore split failures from 3062C (RM C-422) (open access)

Radiometallury examination of three overbore split failures from 3062C (RM C-422)

Three overbore elements, 75Zl2, 75Zl4, and 75Zl5 were discharged from 3062C on April 16, 1962 with longitudinal splits after an exposure of 676. The three elements, two of which had completely split apart, were received on July 5, 1963 to determine the cause of failure. All three elements had failed in the same manner with several full length longitudinal cracks in the uranium extending radially from the canwall to about midway in the core. The failure mechanism was found to be the same as that observed during the examination of worm-tracked overbore elements under RM 456 in which incipient failures had occurred from excessive core temperatures. In two out of the three worm-tracked elements the interior core temperatures had exceeded the beta transformation point as a result of severe cycling conditions. In these three ruptures from 3062C the maximum core temperature had not reached the beta phase; however, the failures were undoubtedly caused by excessive hoop stresses resulting from high internal core temperatures.

Technical criteria and bases reactor gas system: 100-K (open access)

Technical criteria and bases reactor gas system: 100-K

With an increased water plant capacity, the installation of zirconium process tubes and the use of self-supported fuel elements, the power level capability of the K Reactors exceeds the current administrative limit. Exploitation of this capability, if approved, will almost certainly bring about higher graphite temperatures. Because of a continuing concern for graphite oxidation, and because the rate of oxidation increases with increasing graphite temperature, upgrading of the existing K-Reactor gas system through project actin has been proposed. This document presents the technical basis for such project action.

Proposed irradiation of substandard fuel elements. Phase 2 (open access)

Proposed irradiation of substandard fuel elements. Phase 2

The reference letter outlined an initial proposal for irradiating limited categories of substandard fuel elements in the upstream positions of the reactor process tubes. As Phase 2 of this program, a comprehensive study has been made of all current fuel reject categories with respect to use in the upstream low rupture potential positions. This report describes additional ``reject`` fuel categories, the estimated cost savings, rupture potential, and procedures for identifying and handling pieces to fulfill the combined requirements of Phase 1 and 2 of this program. Future methods for grading fuel elements to reduce rupture potential in the downstream reactor positions are also outlined in this report.

Analysis and evaluation of the N Reactor Zone Temperature Monitoring System (open access)

Analysis and evaluation of the N Reactor Zone Temperature Monitoring System

This document reports the result of an engineering analysis and evaluation of the Zone Temperature Monitoring System. The main function of the system is to protect the reactor from localized increases in reactor power which would be reflected by increases in the tube outlet temperatures in the affected zones of the reactor. This function has been implemented by the installation of immersion temperature detectors on 109 representative process tubes. The signals from the detectors will be monitored and will automatically annunciate, initiate a power setback, or initiate a reactor scram should the outlet temperature of one, two, or three tubes exceed an adjustable, preset limit.

The plutonium nitride problem (open access)

The plutonium nitride problem

The WPE progress report for September, 1962 documents reasons for suspecting nitrogen as a possible cause of weapons fabrication difficulties and loss of production caused by radio-graphic rejects. This is a summary and documentation of the ``Nitride Problem`` and related subjects concerning fabrication metal. It contains the background information leading to details published in the Weapons Process Engineering Progress Reports. This summary may provide a better understanding of the problem, since little of the background was suitable for publication in the WPE progress reports.

NUCLEAR AEROSPACE SAFETY PROBLEMS (open access)

NUCLEAR AEROSPACE SAFETY PROBLEMS

Safety problems that have arisen in the conquest of space and are of a nuclear origin are discussed. Space radiation such as cosmic radiation, geomagnetically trapped corpuscular radiation, and solar flare radiation and radiations inherent in nuclear auxilliary power systems are considered. Problems created by the use of nuclear propulsion systems are emphasized. Launch pad problems and core disposal are discussed (M.C.G.)

Stress-Dependent Interactions Between Cesium and Other Materials. Summary Report, February 15, 1962-February 15, 1963 (open access)

Stress-Dependent Interactions Between Cesium and Other Materials. Summary Report, February 15, 1962-February 15, 1963

Metals and alloys germane to thermionic energy converter usage were screened for embrittlement by liquid cesium. Techniques are described for more detailed studies of ceramics and susceptible metals. Definite reductions in tensile ductility were observed for 302 stainless steel and molybdenum. Bend ductility was lowered in titanium, titanium-8 aluminum-4 vanadium alloy, niobium, tantalum, and silver-- copper eutectic solder. Some difficulty in reproducibly wetting samples was evident. Slightly contaminating the cesium with oxygen (or water) was observed to increase cesium wettability. (auth)

PERTURBATION TECHNIQUES FOR THE DEFLECTING MODE

The perturbation metheds used to obtain a relative plot of the electric field and the value of R/Q are described. A method involving radial pulling of dielectric and metallic beads is proposed for the R/Q measurement. The experimental data are shown to agree with the previously presented theoretical predictions.

THE RECOVERY OF MECHANICALLY ENTRAPPED PLUTONIUM FROM CASTING SKULLS AND TURNINGS (open access)

THE RECOVERY OF MECHANICALLY ENTRAPPED PLUTONIUM FROM CASTING SKULLS AND TURNINGS

The small critical mass of plutonium which limits charge size, coupled with its value necessithting quantitative recovery from all residues, makes the direct recovery of mechanically entrapped plutonium from casting skulls and oxidized turnings an economic necessity. The newest method used at the Los Alamos Scientific Laboratory for the direct recovery of entrapped plutonium involves mechanical stirring and vibration of the plutonium melt to physically break up to spongy skull and oxide film, thus allowing the heavier molten plutonium to settle out at the bottom of the melt. The recovery equipment and procedures are described. (auth)

Tory II-C off-design performance

This memorandum reports the performance of TORY II-C at off-design altitudes and Mach numbers. Inlet pressure recovery has been varied with Mach number, reasonable values for a real inlet having been chosen. Nozzle throat area and exit area have been fixed at the design values. Hence this study can be used, in conjunction with missile drag data, to construct a flight envelope.
