The object of this program is to demonstrate that large single-crystal ingots can be economically cast by the Heat Exchanger Method (HEM) and economically sliced into thin sheets with a multi-wafer slicer. An experimental program is described which is designed to demonstrate the potential and isolate the limiting parameters for crystal casting and slicing with the Heat Exchanger Method (HEM) and the multi-wafer slicer.

A SOC one-dimensional calculation of an underground nuclear test is presented to exemplify the shock propagation and spall phenomenology commonly predicted. Then to examine the effects of spherical divergence on spall, a series of SOC calculations, at different radii of curvature, are conducted and prediction of depth and velocity for the first spall zone are compared with predictions from simple analytic theory. The excellent agreement in this comparison verifies that the SOC code accurately represents the physics of spalling. This study also indicates that the total spall depth is independent of divergence because of the compensating effect that subsequent convergence has on the reflected wave. The latter result implies that the total depth of spall calculated for each underground nuclear tests must be critically examined and evaluated. Finally, SOC calculations for nuclear detonations in tuff and granite are performed to demonstrate the significant effect that variations in material response under shock loading have on shock propagation and spall.

The high-pressure safety program at Lawrence Livermore Laboratory, Livermore, California, has been successful in preventing lost-time high-pressure accidents over the past 12 years. Program organization, personnel training and qualification, pressure vessel design criteria and documentation, and pressure testing and inspection are discussed.

An investigation of the nuclear explosions at shallow depth is made. A combination of an explosion code and an effects code proves to be an excellent tool for this study. A numerical simulation of ''Johnie Boy'' shows that the energy coupling to the air takes place in two stages; first by a rising mound, and then by a vented source. The thermal effects are examined for a 1 kt source at three depths of burial. The ''mushroom effect'' leaves a hot radiative plasma in the upper level and cold materials in the lower region of the debris. The temperature and the energy density of the debris can give an upper limit on the thermal output.

This report presents the conceptual design and preliminary feasibility assessment for the hybrid blanket and power conversion system of the Mirror Hybrid Fusion-Fission Reactor. Existing gas-cooled fission reactor technology is directly applicable to the Mirror Hybrid Reactor. There are a number of aspects of the present conceptual design that require further design and analysis effort. The blanket and power conversion system operating parameters have not been optimized. The method of supporting the blanket modules and the interface between these modules and the primary loop helium ducting will require further design work. The means of support and containment of the primary loop components must be studied. Nevertheless, in general, the conceptual design appears quite feasible.

Based on the decision to concentrate on the fluidized-bed reduction of silicon tetrachloride as a candidate process for production of low-cost solar-grade silicon, work during the current quarter was directed toward: (1) evaluation of the economic effects of operating at Zn/SiCl/sub 4/ feed ratios other than the stoichiometric 2/1; (2) design, construction, and exploratory operation of the ''miniplant'' designed to ultimately yield over 200 g hr/sup -1/ silicon for runs of 4 to 6 hr duration. It was concluded that no significant economic advantages exist in operating at Zn/SiCl/sub 4/ ratios on either side of the stoichiometric 2/1. Further, if advantages in reaction kinetics, or in product form or quality can be obtained by off-stoichiometry operation, these advantages might be obtained at only a modest increase in product cost. During the current quarter, design criteria for the miniplant were established, equipment was designed and constructed, and a number of shakedown runs were made which led to equipment modifications for improved operability.

The purpose of this report is to identify, assess, and document the hazards which are associated with the existence of The Special Metallurgical (SM) building at Mound Laboratory. This report is not intended to be as comprehensive as a formal Safety Analysis Report (SAR), although the same systematic approach used to analyze hazards in SARs was utilized to develop this document. Details of the Mound Laboratory site and the approach used to evaluate hazards can be found in other reports which are documented in this report.

A computerized data base of atomic energy levels and atomic transition data has been developed from data published by the National Bureau of Standards. These data are of potential use for laser application. The MASTER CONTROL data-base management system is used. These computerized data can be requested from the ERDA Computer Program Exchange and Information Center of the Argonne National Laboratory or from the National Technical Information Service of the U.S. Department of Commerce.

Annual surveys of fall chinook salmon in the Hanford section (Ringold to Priest Rapids) of the Columbia River have been conducted annually since 1947. Estimates of the relative numbers of fall chinook spawning in this section of the river are obtained through several aerial surveys made each fall. The possible relationships of environmental factors to the size of the local salmon population have been reported for the period 1947 to 1969 (Watson 1970) and each year's survey results are summarized in Battelle Pacific Northwest Laboratory Annual Reports to USERDA (formerly USAEC) Division of Biomedical and Environmental Research. This report was prepared to provide more detailed information than is available in previous reports on the timing of spawning in the principal breeding areas during recent years.
