The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensile behavior was qualitatively similar for all the materials tested. Burst rate maxima centered roughly at 0.1 percent and 1.0 percent plastic strain were observed. The magnitude but not the strain at the low strain burst rate peak was very sensitive to prior thermal treatment, while the higher strain burst rate peak was insensitive to prior heat treatment. An energy per burst maximum was observed at 0.2 percent plastic strain, the magnitude of which was moderately sensitive to heat treatment. The Kaiser effect is observed in the material studied. Emission during compression was similar to that observed in tension. The acoustic emission observed is attributed to dislocation motion, as proposed by James and Carpenter for LiF, NaCl, and Zn.

The size of magnetic moment jumps of a particle in a long, thin equilibrium magnetic mirror field is shown to be related to the complex zeroes of the mirror mode parameter B + 4..pi..dP/sub perpendicular//dB. A consequence is that adiabaticity places a lower limit on ..beta.. than does the mirror mode.

A continuous, cascade dissolver systems, using an air-lift pump for circulation and suspension of solid particles has been developed. This dissolver system has been used to dissolve plutonium oxide, incinerator ash and other residues generated during the chemical processing of plutonium. An integral part of the dissolver system development involved the design and fabrication of a reliable continuous feed system for the dissolver.

Many human vigilance experiments are summarized and principles are extracted which should be useful in designing and evaluating a nuclear material safeguard system. A human is a poor observer and is not a dependable part of any man-machine system when required to function as an observer. There are a few techniques which improve his performance by providing feedback. A conceptual model is presented which is helpful in design and evaluation of systems. There is some slight experimental support for the model. Finally, some techniques of time study and statistical control charting will be useful as a means of detecting nuclear diversion attempts.

Design and assessment of the material control aspect of nuclear safeguard systems requires consideration of three types of functional elements: (1) material handling or processing, (2) actions of adversaries in their attempt to divert nuclear materials from their normal containment, and (3) components of material control and accounting and physical security systems that detect and respond to stimuli generated by the adversary actions. This paper describes a Material Control System Simulator (MCSS) program that simplifies computer simulation of safeguard systems by providing predefined functional models of these three types of elements. Specification of model systems requires only data pertaining to the performance characterization of these functional elements, so users with no prior computer simulation or programming experience can model and study the dynamic performance of safeguard systems. The paper presents an overview of MCSS and an example diversion attempt simulation that illustrates some of the features of the program.

The current status of the LLL program for MC and A system assessment is reviewed. Particular emphasis is given to the assessment procedure and results. The integrated approach we have taken includes many of the functions normally assigned to physical security. Deceit and tampering are explicitly considered. The results of such a detailed assessment include a systematic identification of adversary targets; the most vulnerable portions of the safeguards system; the number and type of adversaries required, in collusion, to fail the system; and the conditional probabilities of safeguard system failure for a variety of assumptions. The assessment procedure was demonstrated by analyzing a prototype fuel cycle facility, the Test Bed. We believe our methodology will be useful to the NRC as a means of performing detailed, objective assessments. The nuclear industry also should find it valuable as a design tool.

An assessment of the effectiveness of the Material Control and Accounting System (MC and A) in a hypothetical nuclear facility, the TEST BED is presented. The key in assessing the TEST BED is the generation of adversary event sets. The adversary event sets are generated and analyzed by a directed graph (digraph) and fault tree procedure. Although the TEST BED is a system hardened against SNM theft, the assessment of the TEST BED finds several major weaknesses, and also indicates possible modifications to correct these weaknesses.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Thoria is irradiated in the Hanford reactors for the production of U-233. The product quality is acutely sensitive to the control of the unseparable contaminant isotopes U-232 and U-238. Recent discussions between personnel of ARCHO and DUN indicate that product quality of a forthcoming separations campaign can be significantly enhanced by analysis of data for which we solicit your support. This letter describes the necessary background and the required analysis. Virgin thoria lots are processed to required transient impurity levels by the National Lead Company of Ohio. They are subsequently shipped to DUN identified by this virgin lot number and are accompanied by the transient impurity levels and U-238 contaminant levels based on statistical samples and analytic chemistry results. Virgin NOL thoria lots consist of various tonnages or fractions thereof, and two or three such lots are typically combined into a single DUN thoria element lot. By weighted averages, the U-238 contaminant level of DUN thoria lots is thus accurately known. The range of U-238 contaminant in any given DUN lot was further controlled by establishing three categories, A, B, and C, with U-238 ranges of 0-1.99, 2.0-3.3, and 3.4-5.0, respectively, on a thoria basis. Thus when a DUN lot …

Scientists are finding increased applications for microcomputers as process controllers in their experiments. However, while microcomputers are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microcomputer programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result--the LLL BASIC interpreter, which operates with LLL's 8080-based MCS-80 microcomputer system. 4 tables.
