Aerodynamic Re-Entry Analysis. Task 2. Thermoelectric Generator Summary Report

An analytical trajectory and aerothermodynamic analysis of a satellite containing a Task 2 thermoelectric generator was completed. A 300-statute mile circular polar orbit was used for this analysis and the launch was assumed to be from Vandenberg Air Force Base. Results of this study show that upon natural decay from a successful mission, the radio-cerium fuel will burn up in space at high altitude, thus only a very minor amount of radio cerium will be released to the stratosphere. A complete a… more

Response of Dual-Purpose Reinforced-Concrete Mass Shelter

BS>A reinforced-concrete dual-purpose underground parking garage and personnel sheiter designed for a long-duration incident pressure of 40 psi was tested. The sheiter was exposed to shot Priscilla, an approximately 37-kt 700-ft balloon burst (June 24, 1957), at a ground range of 1600 ft (predicted 35-psi peak incident-pressure level). The recorded peak incident pressure at the shelter was approximately 39 psi. Postshot soil borings were made to obtain undisturbed samples for determining soil c… more

Upper Atmosphere Re-Entry Study High Altitude Burnup. Volume 2

Methods of determining the fate of radioactive fuels in space power units burned up on re-entry into the earth's atmosphere are reviewed. Particulate characteristics experiments were derived from an analytical study on the ablation of Dlutonium fuel. This study revealed that the particulate size distribution resulting on re-entry burnup is a function of: the fuel form in use and the material velocity and atmospheric density at the time the fuel is exposed. The particulate fate experiments were … more

Studies of Nuclear Resonant Absorption of Gamma Rays. Quarterly Report No. 4 Covering Period June 1, 1961 to August 31, 1961

The effect of polarizing mngnetic field intensity on the nuclear resonant absorption was studied by varying the field strength at a 1-mc Co/sup 57/ source from 0 to 1000 gauss while keeping the absorber between the poles of a magnet having a fixed field of 800 gauss. The rates of resonance absorption change with field intensity were greatest in the region of 300 to 1000 gauss, and the% nuclear resonant absorption for 1000-gauss fields was 8.5 and 26% for perpendicular and parallel fields, respe… more

REACTOR FUEL WASTE DISPOSAL PROJECT PRESSURE-TEMPERATURE EFFECT ON SALT CAVITIES AND SURVEY OF LIQUEFIED PETROLEUM GAS STORAGE

It is deemed feasible to store reactor fuel wastes in a salt dome cavity to a depth where the differential in pressure between the soil over-burden pressure and pressure of the fluid inside the cavity does not exceed 3000 psi, and the temperature is less than 400 deg F. Tests at pressure increments of 1000 psi were conducted on a 2" cylindrical cavity contained in a 6-in. long by 6-in. cylindrical salt core. Tests indicate that the cavity exhibited complete stability under pressures to 300… more

REACTOR FUEL WASTE DISPOSAL PROJECT-PERMEABILITY OF ROCK SALT AND CREEP OF UNDERGROUND SALT CAVITIES. Final Report

A study was made of two problems of salt-cavity storage, namely, seepage of wastes out of formations and closure of cavities due to plastic flow of salt. The results indicate that both problems are negligible; bedded salt is more impermeable than dome salt. Kerosene was found to be nonreactive with dome salt whereas brine solutions showed some interaction. It is concluded that storage of radioactive wastes in salt cavities is feasible. (D.L.C.)

Atmospheric Signals From Explosions and Their Interpretation

Results are reported from a series of experimental highexplosive shots under inversion conditions at the Nevada Test Site which were made in an attempt to refine blast prediction techniques. Applications of the data in determinations of the amount of energy which remains in the blast wave as it reaches acoustic level and in determinations of the magnitude of the reflection factor when the blast wave strikes the ground are discussed. Data on shock wave propagation are presented graphically. It i… more

Experimental and Analytical Reactivity Studies of Clean Critical Stainless Steel Cores

ABS>The results are presented of critical water height measurements made on close-packed lattices of Spert III, highly enriched, plate-type, stainless- steel-clad fuel elements. Experiments were conducted with cores containing no control rods and with cores containing a single, fully-inserted control rod. The "clean critical" data obtained in these experiments were used to test the validity of various aspects of a four-group, diffusion theory analysis of the full scale Spert III reactor. The re… more

Telescopic zoom lens attachment for magnified views in underwater radiation environments

This document consists of the notes that accompany a slide presentation (15 slides). The discussion begins with the need for the Telescopic Zoom Lens or TZL; why is was designed and fabricated as well as the design restraints that dictated its final form and function. Next is the use and modification of existing equipment; equipment that was used to remotely scan a nuclear reactor tank using eddy current and ultrasound. The uniqueness of the TZL mechanism itself is discussed; how it meets the d… more

Modular OTEC platforms, SKSS designs. Volume I. Executive summary. Final report

One of the possible options for generating electrical energy from ocean thermal gradients requires the use of a floating offshore platform. The platform would contain all OTEC (Ocean Thermal Energy Conversion) systems and power cycle components and consist of the hull, seawater, station-keeping, platform service, and mission support subsystems. It would be stationed at one of the designated OTEC sites, and would transmit the generated electricity to the shore power networks by means of an elect… more

Report on technical feasibility of underground pumped hydroelectric storage in a marble quarry site in the Northeast United States

The technical and economic aspects of constructing a very high head underground hydroelectric pumped storage were examined at a prefeasibility level. Excavation of existing caverns in the West Rutland Vermont marble quarry would be used to construct the underground space. A plant capacity of 1200 MW and 12 h of continuous capacity were chosen as plant operating conditions. The site geology, plant design, and electrical and mechanical equipment required were considered. The study concluded that … more

Disruption of satellite-to-ground station communication links by nuclear fireballs

Diffraction around nuclear fireballs near the line of sight for satellite-to-ground communication links is calculated numerically. The geometry allows assumption of geometric optics and plane-wave signals. The fireball is modeled as an opaque disk normal to the line of sight. The effect of disk shape and edge taper is considered. 13 figures, 1 table.

Performance study of a thermal-envelope house: Phase II. Cooling performance. Final report

The thermal envelope house is shown to perform much better than conventional houses without mechanical refrigeration and better than one would expect from most passively cooled houses in the hot-humid climate of Georgia. Peak temperatures inside the house were 8 to 15/sup 0/F below peak ambient temperatures. Peak inside temperature measured during the test period was 80/sup 0/F with an outside ambient peak of 93/sup 0/F. Air flow rates within the envelope were less than 1 ft/sec even when the a… more

F.C.D.A. Family Shelter Evaluation

In order to determine the effects of atomic explosions on small civil defense shelters for family use, 29 simple structures were built along an arc 1200 ft from the target point and exposed to Buster Bursts B, C, and D. The structures were of four basic types; covered-trench, metal-arch, wood-arch, and basement lean-to. Because of poor cohesive properties of the soil, much of the earth cover on the shelters was removed by the first shot. Since test procedures prevented restoration of structures… more

Contour plotting programs for printer and Calcomp plotter. [RIPA, RIRA, for CDC 6600]

Contour plotting programs for plotting contour diagrams on printers or Calcomp plotters are described. The subroutines also exist in versions that are useful for the special application of finding minima and saddlepoints of nuclear potential energy surfaces generated by the subroutine PETR3 of another program package. For the general user, however, the most interesting aspect of the plotting package is probably the possibility of generating printer contour plots. The plotting of printer contour… more
