SNAP II is the designation for a 3-kw nuclear auxiliary power untt to be used in a satellite vehicle. This system consists of a reactor heat source, a mercury Rankine engine and an alternator. The alternator, mercury pump, turbine, and reactor coolant pump are mounted on a common shaft supported by mercury lubricated bearings. Design details and test results concerning the combined rotating unit (CRU) development are described. (auth)

The probability of accidents to tractor semitrailers is developed through analysis of accident frequency data in relation to season; geographical factors; road type, traffic and populatlon density; and type of carrier business. Maximum likelihood rates are developed for the potential carriers of radioactivity. Impact characteristics of accidents are studied through the analysis of mass, speed, and energy relations and the effect of these on vehicle and cargo damages is explored. (auth)

The alloying of zirconium to improve corrosion resistance has an empirical basis, and satisfactory explanations for the alloying effects are not available. A theory of compensating valencies in the corrosion oxide is proposed, in which cations of lower and higher valence than zirconium (+4) are present in ratios such that electrostatic neutrality is ensured. An example is an alloy containing equimolar amounts of scandium (+3) and niobium (+5). A number of zirconium alloys were prepared in which scandium or yttrium were paired with elements capable of a +5 or +6 valence. The ternary alloys containing scanadium were superior to the alloys combining yttrium. The alloys containing scandium plus molybdenum, tantalum, or tungsten had relatively long lifetimes in steam at 540 deg C and 600 psi as compared with other alloy combinations, including Zircaloy-2. A quenched alloy containing 0.025 wt% Sc and 0.053 at.% Mlo, that is, 0.05 mol.% of each additive, corroded approximately according to a cubic law up to 758 hr, at which potnt the rate suddenly increased in a manner suggesting hydrogen damage. Examination of the oxide film from alloys containing scandium and molybdenum showed only monoclinic ZrO/sub 2/. It is believed that stabilization of this form of …

Results are presented of short time, high heat flux capsule irradiations to determine the magnitude of plastic strain induced in the capsule cladding due to UO/sub 2/ thermal expansion. Annular geometry capsules were employed with both internal and external cladding and forced convection cooling of both surfaces to simulate the reference superheat fuel element design. Both 304 stainless steel and 3003 aluminum claddings of various thickness were used to determine the influence of cladding strength. The initial gap spacing was purposely varied as an additional parameter. The program was undertaken as a part of the effort to evaluate plastic strain cycling as life limitation in the use of thin fuel element cladding. An over-all summary of the experimental results is included. (auth)

Design studies were performed and costs were estimated for an air transportable, 10 Mw(t), pressurized light water thermal circulation reactor, combined with a direct conversion thermoelectric generator and static electrical inversion equipment. This TCR-TE'' concept appears to have potential for ultimate use as a remote unmanned power station. Based on an extrapolation of present reactor technology and on assumed thermoelectric materials properties forecasted to January 1, 1963, a net a-c electrical output of 315 Kw is estimated, assuming the use of 80 deg F local water for cooling purposes. An alternate concept using 80 deg F air for cooling produces 271 Kw, net. These electrical output figures can be improved significantly through a recommended research and development effort. The design and construction of a prototype plant is also recommended. (auth)

Optimum conditions were determined for the precipitation of neptunium(IV) peroxide from nitric acid solutions. The results indicate that the precipitation could be applied successfully on a plant scale. Data are presented for the solubility of neptunium peroxide in solutions of nitric acid and hydrogen peroxide. The solubility is less than 10/sup -4/M in 1.5 to 2.5M nitric acid containing 4.5M hydrogen peroxide. Two crystalline modifications of the peroxide were prepared; these two crystalline structures were similar to structures previously reported to plutonium peroxide. (auth)

A detailed presentation is made of the thermal stresses calculated for the moderater elements in the Experimental Gas-Cooled Reactor. These results are discussed and some conclusions are presented. This report complements a previous report, BMI-1503, which defines the problems and discusses the methods of solution. (auth)

A better understanding of the maximum operating characteristics that can be achieved with the use of UO2 as a reactor fuel is the primary purpose of this program for Euratom and the Atomic Energy Commission. During this program work will be undertaken in two areas that have been of concern to the reactor core designer for a long time, viz. fission gas release and central melting in fuel rods.

Photograph of Stan Kenton standing next to Georgi Edwards (Miss New Mexico) and Jimmy Paul from station KOB (NBC) Albuquerque. The three are posing together behind a microphone on a stand; Miss Edwards is holding a large bouquet of flowers. Behind them, men holding instruments are sitting in rows. The photograph was most likely taken at the Officer's Club at Sandia A.F.B. in Albuquerque, New Mexico.

The population distribution and the associated thermodynamic properties of a three-level maser are calculated. By treating the three spin states as individual chemical species, it is possible to write the partition function, free energy, internal energy, entropy, and chemical potential for each species. The principle of minimum entropy production is used to derive an equation of reaction equilibrium. This equation is used in separate thermodynamic and statistical mechanical calculations to obtain the normalized population distribution. This result agrees in first order with that obtained by means of the rate equations. Competitive relaxation processes and partial saturation effects are discussed. The saturation parameter used is the one defined in the treatment of the Overhauser effect. An explicit expression is obtained for this parameter in terms of the various transition probabilities, and its effect on maser performance is discussed. (auth)
