LLL comments on The Ultimate Catastrophe

Description: This correspondence provides a discussion of purported hazards of nuclear energy production and weapons research. The possibility of atmospheric burn and oceanic burn are discounted, and the cross sections of Nitrogen are investigated and the concentration of D[sub 2]O in the oceans are considered. In conclusion, extremely conservative calculations demonstrated that it is completely impossible for either the earth`s atmosphere or sea to sustain fusion reactions of either thermonuclear nuclear chain reaction type. And, in particular, such reactions cannot be triggered by the explosion of nuclear weapons, even those having unrealistically high yield and impractical high yield-to-weight.

Separable high explosive systems

Description: A number of approaches have been considered regarding the feasibility of separable high explosive systems for possible application in the Super Safe Program (Ambassador). After a very brief and limited investigation we have categorized various systems and given examples. The two basic approaches in the Ambassador program appear to be: Movement of fissionable material, and movement of explosives. Since explosives are our business, we will comment only on the latter approach. Movement of the explosive could entail small amounts of HE, such as for a detonator, booster, or a portion of the main charge.. These possibilities tend to beg the issue of true safety and dispersal. Movement of the entire main charge or of separate non HE components is certainly more desirable. Separable explosive systems are discussed.

Materials Engineering Laboratory interim report, LF-8 and LF-9 support pad fabrication

Description: This project was for the fabrication of 50 LF-8 and LF-9 support pads (clamshells) which would conform to the Los Alamos Scientific Laboratory (LASL) drawing provided in Appendix A of this report. Discussions on this contract were initiated in early October and involved delivery of all the pads by January 31, 1977. The project was modified to deliver only 10 pads by the above date. However, since the period encompassed Thanksgiving.and Christmas shutdowns, it was decided that delivery of four units by February 11, 1977 would be satisfactory to all concerned. The remainder would follow on a timely basis. This report outlines the status of the project at the present time. The data are divided into the following categories for clarity purposes: Mold master definition and fabrication, Process drawings, and Mold and piece part fabrication.

Brief summary concerning strategic withholding (nuclear parsimony)

Description: This memorandum provides a brief summary on thoughts concerning `Strategic Withholding` (or perhaps, `Nuclear Parsimony`). It is chiefly meant to further support the view that there should be other significant doctrines besides `Brute-Force Retaliation`. The basic doctrinal argument is that it may be broadly disadvantageous to fire one`s missiles in equal, or `total` retaliation. It may be better to reply only softly, or not at all. The basic justification rests on an assumption of extended war, and on a logic addressed to what`s best for the surviving population and capability at any given point. In most strategic wargame exercises, it is rarely apparent that this principle is taken into account. The essential point of argument is that an extended war is not so different from peacetime posturing.

Explosive performance. Quarterly report, April--June, 1970

Description: The objectives of this study are the determination of detonation velocity, shock sensitivity, impact sensitivity, etc.; and the acquisition of high precision one-dimensional hydrodynamic data for use in establishing detonation product equations of state, performance of explosives, etc. A three-shot wedge test series was fired with RX-08-AZ. In terms of transmitted pressure, its sensitivity is comparable to that of LX-09-0. An exponential model was studied as a possible substitute for polynomials in fitting cylinder test data.

Slow PBX development. Quarterly report, October--December, 1971

Description: 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.

Extrudable explosives. Quarterly report, October--December, 1971

Description: 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.

ANFOL synthesis. [Quarterly report], April--June 1971

Description: A new method was developed for chlorination of 4,4-dinitropimelic acid with PCl{sub 5} using a Soxhlet extraction apparatus as the addition vessel. Acid used was that reclaimed from the purification of the crude acid chloride of 4,4-dinitropimelic acid supplied by LRL. Synthesis of FEFO plasticized AFNOL has been scaled up to a nominal 30-pound batch. Small batches and cure tests were run prior to the scaleup. Cure rate of the AFNOL system was followed by infrared spectrophotometry. The temperature range of 40-100 C was studied using the hot stage attachment to the infrared spectrophotometer.

Development of PEX explosives phase diagram studies. Quarterly report, October--December, 1971

Description: 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.

Explosive material qualification chemistry sublimation studies of hexanitroazobenzene (HNAB)

Description: Sublimation studies of hexanitroazobenzene (HNAB), Sandia Lot 43-11-B, have shown all sublimation residues to be essentially HNAB (form 3), with HNAB (form 2) found in the sublimates. The sublimation condensate in the lower temperature ranges (80--130 C) has a non nitro group material, and an HNAB like (nitro group) material was found in the 160--190 C condensates. The presence of aliphatic impurity(s) in all fractions, from 80 to 220 C, has been determined albeit the concentration decreases significantly at the higher temperature ranges (200--220 C).

AFNOL synthesis. Quarterly report, October--December, 1971

Description: 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.
