Radioisotope and Radiation Applications. Quarterly Progress Report

Description: An evaluation was given of the possible hazards to consumers from radioisotope residues in consumer products. A laboratory demonstration was given of the use of Mn/sup 54/ to facilitate removal of manganese from process feed water. lt was found in the hazards evaluation that the "worst case" of radiation exposure from residual radioisotopes in steel gives a radiation exposure somewhat less than the maximum allowable dose levels for occupational exposure. Initial study indicates that for actual … more

THE SNAP-II POWER CONVERSION SYSTEM. TOPICAL REPORT NO. 4. TURBINE DESIGN AND TESTING

Description: SNAP II is the designation for a 3 kw nuclear auxiliary power unit to be used in a satellite vehicle. The SNAP II system consist of a reactor heat source, a mercury Rankine engine, and an alternator. A two stage, full admission, axial flow turbine was chosen for this APU application. Design details and test results are presented. (auth).

Possible Use of a Betatron Core on the Cosomotron

Description: Most existing electron synchrotrons use betatron start for initial acceleration of the particles. The subsequent synchrotron acceleration is then performed with a nearly constant radio-frequency. Investigation of the effect of turn-on rate and initial energy spread is made mathematically. Several advantages are seen for such a technique. (D.C.W.)

RADIOISOTOPE AND RADIATION APPLICATIONS. Quarterly Progress Report

Description: Exploratory and optimization experiments in the use of in-process isotope neutron sources to produce short-lived intrinsic radiotracers were initiated. Flux determinations using manganese sulfate solutions and indium foils were performed. The maxtmum thermal-neutron flux measured by indium acttvation was found to be 9.6 x 10/sup 4/ n/(cmsup 2/) (sec) for a 10-curie polonium-beryllium source. The peak flux occurred 3.2 cm from the center of the source through approximately 1.6 cm of water modera… more

Engineering Report on the Design of the Pratt & Whitney Aircraft Forced Convection Alkali Metal Vaporization Condensation Heat Transfer Rig

Description: Summary. A test rig has been designed to obtain basic two phase forced convection liquid metal heat transfer and pressure drop data for use in the design of liquid metal boilers. This engineering report includes background of the boiling problem, partial summary of work done by other investigators, the object, scope, engineering, and operations of this test rig, and a summary of reproducibility tests conducted in a water back-up rig.

Influence of Different Y Chromosomes on Secondary Nondisjunction in D. Melanogaster

Description: Females heterozygous for a wildtype X chromosome from a Samarkand stock and an chromosome of the composition [formula] were tested for the frequency of X-chromosomal non-disjunction and segregation of the X's when Y chromosomes of different types were present in the females. The Y chromosomes used were 1) a normal unmarked Y, 2) [formula], 3) [formula] and 4) [formula] (a chromosome which arose in one of our experiments and has not yet been analyzed). Since this was only a preliminary test no a… more

Experimental Investigations of the Removal of Sodium Oxide From Liquid Sodium

Description: Experimental investigations were conducted to obtain additional information on the growth and characteristics of sodium oxide deposits in liquid sodium which could lead to system plugging. These investigations included the removal of sodium oxide from molten sodium by the cold trap method.
