AFNOL synthesis. Quarterly report, October--December, 1971
Five batches of unplasticized AFNOL, each approximately one pound, were synthesized using 4,4-dinitropimelic acid as the starting material. Two 10 g batches were completed prior to the pound batches to assure the usability of the acid chloride. Characterization of each of the larger batches was by differential thermal analysis (DTA), infrared spectrophotometry (IR), and cure tests. Some characterization was also done on the commercial chemicals used in the synthesis.

Component D-charge. Quarterly report, October--December, 1971
Several different shaped-charge configurations were tested. Charges with an included angle of 60{degree} and brass conical liners were determined to be more satisfactory. Existing loading equipment was used to extrude Rx-08-BD into the final design.

Development of a Venturi Type Bubble Generator for Use in the Molten-Salt Reactor Xenon Removal System
A venturi type bubble generator was developed for application in the xenon removal system proposed for a molten-salt breeder reactor. Gas injected into the high velocity liquid at the venturi throat is fromed into bubbles by the fluid turbulence in the diffuser cone. Tests were conducted using aqueous solutions to determine the various pressure drops of the bubble generator as a function of liquid and gas flow rates and to determine the bubble diameter produced. Empirical relationships were developed which could be used in combination with the more conventional fluid flow equations to predict the overall head loss and the gas injection pressure of the bubble generator. A dimensionless correlation for predicting the bubble diameter was developed for bubble generators of similar geometry.

Development of PEX explosives phase diagram studies. Quarterly report, October--December, 1971
Experiments have been carried out to determine the solid-liquid phase diagrams of binary mixtures of FEFO, EDNP, BDNPA and BDNPF. Cooling curves for the mixtures give no indication of crystal formation. Penetration measurements indicate a glass transition for all of the mixtures below {minus}40 C. The existence of glassy states for the mixtures was confirmed by visual observation with a polarizing microscope. Thermomicroscopy has been used in the preliminary study of the phase behavior of four binary mixtures. So far no eutectic has been observed.

Encapsulation of explosive particles by parylene. Quarterly report, October--December, 1971
Parylene is the generic name for members, e.g. parylene N,C,D of a thermoplastic polymer series developed by Union Carbide (Reta is a trade name for the materials). All of the members are laid down by a vacuum, vapor deposition process. The properties and uses for each member of the series differ from each other, but collectively the Parylenes have a wide range of applications. Gas permeability and moisture vapor transmission of Parylene C are very low. These properties make Parylene potentially very useful with or near explosives or components. One of the forms, Parylene C--the monomer of dichloro-di-p-xyly-lene--is potentially attractive. Its density is 1.29 g/cc. In this study the initial emphasis will be on the feasibility of coating HE particles. Substrates of diminishing particle size will be encapsulated to establish the particle-size limitation of the process.

Extrudable explosives. Quarterly report, October--December, 1971
Several extrudable HE formulations using, principally, HNAB as the explosive component were examined in efforts to develop an extrudable composition more temperature-resistant than Extex. It is shown that extrudability is dependent upon particle character, wetting of the binder compound, roll-milling technique and the addition of fine metallic oxides to improve flow properties, while detonability is dependent upon explosive concentration, a hard cure, and the shock parameters of the confining media.

Fillers and potting compounds. Quarterly report, October--December, 1971
The work this period concentrated on packaging RTV silicone fluids in a commercial purchased package-bag. The samples will be stored for a period of six months at ambient temperature. Because of the rigid film of the Bipax Bag, it is doubtful that this method of packaging silicones will develop into an acceptable process. To enhance this process, a more pliable bag should be incorporated into the packaging system.

Isostatic pressing development. Quarterly report, October--December, 1971
About 150 process-development pressings were made in prototype tooling. Problems arose which include stress cracking caused by difficult stripping of the part from the mandrel. Pressings made of PBX 9404 presented none of these problems. The primary effort is being directed toward developing a process for LX-09 and LX-04 pressings which at present are the problem areas.

Metallized explosives. Quarterly report, October--December, 1971
In addition to the DTA, X-ray diffraction, and Henkin test results on silvered BTF reported earlier; impact sensitivity via drop hammer and chemical reactivity via gas chromatography were conducted with all results generally indicating no significant compatibility problems. One larger batch, {approximately} 15 grams of silvered BTF was made from which pressed-to-shape pellets were fabricated at a desired density of approximately 90% of TMD.

Pressing technology. Quarterly report, October--December, 1971
A new process has become available that might be useful for compacting PEX materials. The process is triaxial: it utilizes the familiar isostatic compression vectors to form a billet and for lateral reinforcement while a shear action of higher pressure is included over the billet ends with a mechanical punch. The 20-inch press has been inspected at the site of manufacture and is in transit to Pantex Plant.

Slow PBX development. Quarterly report, October--December, 1971
A total of nine batches of pressable baratol and pressable Composition B-3 were made and analyzed. One pressing was made for P/040 fabrication and test fire. The first P/040 plane wave lenses designed were fabricated and fired, yielding a center-leading average of 0.17 {micro}sec asimultaneity. The interface contour was redesigned and two lenses were fabricated and fired, resulting in center-lagging asimultaneity of 0.098 {micro}sec and 0.074 {micro}sec.
