This report provides preliminary design and specification information to fabricate a compact Weapons Effects Display System. The system is capable of calculating and displaying the effects of thermal flux, radiation, and blast pressure from a nuclear weapon. EG&G was asked to evaluate analog computer logic of an existing Weapons Effects Display System (WEDS), make the necessary changes and develop preliminary specifications to fabricate a more compacted system. Also included was to design any new circuits required to make the system more accurate, and design new circuits to provide additional features as specified by LRL. The WEDS consists of an analog computer to compute the effects of thermal flux, radiation and blast; a display system for displaying the pertinent digital information; and a map display system for presenting certain information on a map. The weapon effects are represented by equations taken from ``The Effects of Nuclear Weapons,`` by S. Glasstone, other nuclear weapon effects documents, and from individuals working in the nuclear weapon field. These equations are solved with the use of an analog computer. The equation results, along with pertinent input information, are displayed on a digital readout panel and as an overlay on a map display system. The compact …

Direct AEC sponsored programs report that: a new mathematical simulation model to handle reactor effluent dispersion was started, final arrangements were concluded for the proposed test of the effectiveness of activated carbon for inorganic ion removal at the Richland Water Plant, the whole body counter used to measure the burdens of radionuclides in Richland school children is being calibrated for persons of small size and with different weight to height ratios; controlled intake of oysters that have accumulated zinc-65 is being used as one phase of this calibration. Assistance to Douglas United Nuclear is reported for missions 1, 10, 11, 13, and 14. Topics discussed here include: diffusion bonding of nickel-aluminium, PCTR experiments, code development, aluminium jacketed uranium fuel elements, and radiochemical analysis of radioarsenic in effluents. The General Electric N-Reactor department reports on:analysis and theoretical interpretation for ice and water, radiometallurgical examination on Al canned targets containing ceramic cores, inspection of irradiated zircaloy-2 clad fuel rods,resonance absorption cross section calculations, and visual inspection of Inconel steam generator tubes. Isochem reports on: dissolution of zircaloy studies, subcritical neutron interaction experiments, carbon monoxide disproportionation on exposure to bismuth oxide, dissolution rates of British alloys in nitric acid, Sr and rare earth …

This report details 200 Area activities for the month of July 1966.

The surveillance photography of underground nuclear detonations at NTS was engineered by EG&G to furnish the following information on unexpected venting: (1) establish when, with respect to zero time, the venting occurred; (2) record the point or points of emission of the venting gases; (3) show the colors, if any, of the venting gases; (4) the direction of cloud travel; and (5) dimensions and volume of the cloud as a function of time. In addition, the film records provide a color documentary film including a record of gross surface motion and a record of unexpected surface phenomenon (such as in Longshot). Surveillance coverage starts at minus 5 seconds and continues to plus 30 minutes. This report describes the typical photographic program setup, films used, and film processing.

A small, self-powered, acoustic transponder was designed, fabriated, and tested to demonstrate the feasibility of producing a minimum-szie transponder package capable of operating at slant ranges of several miles in a deep-water environment.

Submitted herewith are source and special nuclear material composition of ending inventory reports for the month of July 1966. Normal uranium, depleted uranium, plutonium, thorium, U-233, tritium, deuterium, enriched lithium, neptunium 237 and plutonium 238 are all inventoried.

SNAP 10FS-3 was the first flight-qualified SNAP reactor system to be operated in a simulated space environment. Prestart-up qualification testing, automatic start-up, endurance period performance, extended operation test and reactor shutdown are described as they affected, or were affected by, overall reactor performance. Performance of the reactor control system and the diagnostic instrumentation is critically evaluted.
