An investigation of the feasibility of building a harbor on the West coast of South America using explosive power of nuclear weapons, a preliminary report

Description: There is an interest in discovering the various peace time uses of nuclear explosives. One of the proposals is the building of harbors. There are several ports along the west coast of South America where lighterage is necessary. This implies a need for expanded harbor facilities. The problem is to find a good location for creating a harbor, and the feasibility of accomplishing this with the use of nuclear force. Feasibility includes blast effects, radiation hazards, the number of weapons needed, and economic considerations. Economic considerations include the cost of treating a harbor of sufficient depth and area, the building of harbor facilities, and the estimated savings and advantages of the new harbor. Several meetings were held with naval personnel of the Military Liaison group at UCRL to discuss the general problems of harbors. Thirty-three different ports were given a preliminary investigation.

Trafficability of Soils: Effects of Surface Conditions on Drawbar Pull of a Wheeled Vehicle

Description: "A study was conducted to (a) investigate the effects of soil surface conditions on one-pass drawbar pull capabilities of a wheeled vehicle, (b) relate optimum drawbar pull to soil strength as measured by several instruments, (c) develop tentative equations for predicting optimum tractive coefficient, and (d) determine effects of tire characteristics (tread pattern and deflection) on drawbar pull. One hundred and six drawbar pullslip tests were conducted with a 3/4-ton M37 truck at a gross weight of 7240 lb. One tire size (9.00-16, 8-PR), two tread patterns (smooth and nondirectional military), and two tire deflections (15% and 35%) were tested. Surface conditions varied from dry and firm, to wetted with small amounts of water, to flooded. Asphalt surfaces also were tested" (p. xi).

Plowshare sequential device test

Description: For over a year we have been advocating the development of a hardened or ruggedized version of Diamond which will be suitable for sequential detonation of multiple explosives in one emplacement hole. A Plowshare-sponsored device development test, named `Yacht` is proposed for execution in Area 15 at the Nevada Test Site [NTS] in late September 1972. The test is designed to evaluate the ability of a ruggedized Diamond-type explosive assembly to withstand the effects of an adjacent nuclear detonation in the same emplacement hole and then be sequentially fired. The objectives and experimental plan for this concept is provided.

What would the Lab do in case of a complete text ban

Description: The impacts of a complete test ban on the programs and personnel at the Lawrence Radiation Laboratory. The weapons program with its four major sub-programs are discussed as are those programs outside the weapons arena. The utilization of scientific and technical personnel is also detailed.

Use of implicit Monte Carlo radiation transport with hydrodynamics and Compton scattering

Description: The purpose of this note is to show that the combination of implicit radiation transport and hydrodynamics, Compton scattering, and any other energy transport or exchange mechanism can be simply carried out by a splitting procedure. This means that the contributions to material energy exchange can be reckoned separately for hydrodynamics, radiation transport without scattering, Compton scattering, plus any other possible energy exchange mechanism. The radiation transport phase of the calculation would of course be implicit and would be carried out in exactly the manner described in UCRL-7294 but the hydrodynamics and Compton portions would not, leading to possible time step controls. In any case, the time step restrictions which occur on radiation transfer due to large Planck mean absorption cross-sections would not occur.

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.

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.

A Technique for Quantifying Forest Stands for Management Evaluations

Description: "In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed" (p. ix). Results show significant differences in tree productivity as a result of fertilization and changes in heights, bole diameters, etc.

Deflection-Coverage Relationship for Flexible Pavements

Description: Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield and highway data and for airfield data only. The relationship of wheel load and tire pressure is given, and a multiple-regression equation was determined to predict coverages as a function of wheel load, tire pressure, and deflection" (p. xi).

Shock-Absorbing Materials, Report 2: Cellular Concrete as a Backpacking Material

Description: Partial abstract: "The use of low-density cellular concrete, having an oven-dry unit weight of 50 pcf or less, as a backpacking material for deeply buried protective structures was studied. Cellular concrete was found to be suitable for this type of application. A number of physical properties of cellular concrete were determined to provide input to design codes" (p. 4).
