New Developments in the Theory of Pressure Broadening

Description: An investigation was made into various branches of the theory of pressure broadening by solving two problems: that of treating the motion of the perturbers quantum mechanically and that of overlapping lines. Both problems are solved only in the impact approximation, but this is adequate when the perturbers are electrons, which is the practical case. In addition, the validity conditions of this approximation are examined. (auth)

Crud Pick-up by Mixed Bed Ion Exchange

Description: The residual capacity of mixed resins during the first nine weeks of contact was determined with a synthetic crud in aqueous solution (crud is primary loop water containing suspended corrosion products) containing not less than 5 g of crud per 100 ml of wet resin, and it was compared with the residual capacity of individual cation and anion resins under similar conditions. When fresh anion and cation resins individually and mixed were contacted with a fresh synthetic crud in the range 1.33 to 7… more

On the Dynamic Design of Non-Regenerative Transistor Circuits : Report No. 94

Description: In this technical report, firstly, the transfer function of a non-regenerative, base-driven transistor circuit is derived by applying the linear equivalent circuit method. The results are experimentally verified. Secondly, the idea of the inverse-gain-bandwidth is introduced as the criterion of the dynamic design. Thirdly, the stability factor is explained. Finally, it is shown that a system constructed by various types of transistor switching circuits is reduced to a long train of unit chains … more

Reaction of Graphic with Sodium

Description: Most of the publications in the open literature available to us agree that sodium does not readily react with graphite, though potassium, rubidium, and cesium readily enter between the planes of the graphite lattice. In view of the conflicting evidence available, it seems inadvisable without very extensive further study to consider the use of graphite in direct contact with liquid sodium, except under very mild conditions of temperature and irradiation, and then only with very pure sodium and c… more

Sources and Availability of Helium

Description: A review of helium sources, availability, consumption, and future production capacity indicates that the helium consumed in the operation of 100 helium-cooled reactors for 300-Mwe power plants over a 20-year period will run no more than a few per cent of the helium consumed in the U. S. in the next 25 years and less than 1% of the helium that is to be stored during that period under the helium conservation act of 1960 (Public Law 86-777).

Estimation of Reaction and Heat Release Rates for Graphite Oxidation

Description: A literature study has been made of rates for the reaction of oxygen with high-purity artificial graphite. Values from a number of sources have been expressed on a common basis which provides approximate correction for the retarding effects of oxygen diffusion in the graphite pores. The corrected rates can be correlated by the equation k = 7.24 x 10^9 exp (-22 100/T), where k has units of weight fraction oxidized per hour and T as in °K. Effects of oxygen concentration, solid and gas-phase cont… more

Theoretical Study of Single-Transfer Line Concatenated Pulse Column Systems

Description: Calculations indicate that single-transfer line concatenated pulse column systems can be operated with static pressures that are not excessive if a sufficient number of vessels are employed in the system. The required number of vessels can be attained by using a series of short columns or by using holdup pots in conjunction with a limited number of columns.

Determination of Thickness of Oxide Film on Phosphor Bronze

Description: The thickness of an oxide film on phosphor bronze helices was determined by first establishing the oxygen content of the helix "as received" and after cleansing with nitric acid. Based on the assumption that the difference between these two values was the oxygen in the film, and that the film consisted entirely of cupric oxide, the thickness of the film was calculated from the density of cupric oxide, weight of the film, and surface area of film. A value of 1080 A was calculated as the thicknes… more

Operation of the HRT Mockup with Boiling Fuel in a Titanium Pressurizer, Run CS-23

Description: The 0.045m UO2SO4, 0.036m CuSO4, 0.025 m H2SO4 solution (HRT fuel composition) was chemically stable during 1, 866hr of operation at 280ºC and 1500 psi. The system was pressurized by boiling a 0.4 gpm stream of the fuel in a titanium heat exchanger at 313ºC.

Dynamic Corrosion Screening Tests on Inconel and Nickel in NaCl-MgCl2-UCl3 Bath

Description: Nickel is more susceptible to mass transfer in a 100hr non-isothermal dynamic corrosion system than is Inconel when exposed to a NaCl-MgCl2-UCl3 (50.0-33.3-16.0 mole %) bath at a hot zone temperature 1800 F. No nickel mass transfer was observed in a 500-hr test at 1350 F, but Inconel showed some attack under these conditions. Inconel mass transfer was observed in both tests, being more severe at the higher temperature. On the bases of these preliminary tests, it appears that nickel is a more… more

Measurement of the Friction Characteristics for Flow in the ART Fuel-to-NaK Heat Exchanger

Description: The friction characteristics of a full-scale straight-tube model of the ART fuel-to-NaK heat exchanger were determined experimentally. The presence of the spacers resulted in a transition to semi-turbulent flow at a Reynolds modulus of 350. this semi-turbulent flow persisted up to a Reynolds modulus of 5,000. The circumferential spacers were found to contribute slightly more than the radial spacers to the pressure loss in the heat exchanger.

Calculation of Wall-Scattered Gamma Radiation Escaping through a Shield Opening - Application to the HRT

Description: A simplified method was developed for calculating wall-scatter gamma radiation escaping through a shield opening. The method was applied to the HRT and the results showed that next to the line of sight contribution, scattering of the wall of the shield opening was the main contribution to the dose at the rear edge of the shield. Design charts were prepared that give the dose as a function of the gamma source location with the reactor cell.

Low Pass Filters For Telemetering Applications

Description: With exacting requirements imposed upon the operation of the subchannel modulators used in the FM-FM telemetering system, it became necessary to obtain a filter suitable for use in conjunction with the subcarrier oscillators in order that the desired distortion level could be effectively maintained. This paper describes, both theoretically and practically, a filter which was found to satisfactorily fill the required specifications.
