Preliminary Studies of Scavenging Systems Related to Radioactive Fallout. Summary Report

Description: Preliminary studies were made of the relationship between the size of particles suspended in the lower atmosphere and the amount and nature of radionuclides they contain. Emphasis was placed on the distribution of strontium90. From a limited number of analyses, it was found that strontium-90 is associated primarily with particles below 0.1 micron in diameter. Preliminary studies were made of scavenging of particles by liquid water droplets. Studies are included of sticking probability and the e… more

Spectrophotometric Determination of Copper in Yttrium Metal With Neocuproine

Description: The neocuproine colorimetric method was applied to the determination of copper in yttrium metal. From 5 to 80 - g of copper was determined in the presence of as much as 5OO mg of yttrium with a coefficient of variation of 2%. Copper was reduced to copper (I) with hydroxylamine and complexed with neocuproine (2,9-dimethyl-1,10-phenanthroline). The colored complex was extracted into chloroform and its absorbance measured, after dilution with ethanol, at 457 m - . (auth)

DETERMINATION OF TETRAVALENT URANIUM IN THORIUM OXIDE-URANIUM OXIDE MIXTURES. PARTS I, II, AND III

Description: For the determination of milligram quantities of uranium(N) in thorium oxide-uranium oxide mixtures which may also contain uranium(VI), it was necessary to devise a means of dissolving the sample so as to prevent any air oxidation of the uranium(IV) to uranium(VI). For this determination, the conventional potassium dichromate volumetric method was used except that the sample was dissolved under reflux in 7 M H/sub 3/PO/sub 4/ which contained an excess of standard dichromate solution. Following … more

THERMAL EXPANSION OF URANIUM DIOXIDE. Final Report

Description: The thermal expansions of commercial uranium dioxide specimens were measured up to the melting point. The linear expansion of dense, normal grain size UO/sub 2/ follows closely the equationi L = L/sub 0/(1 + 6.0 x 10/sup -6/t + 2.0 x 10/sup -9/t/sup 1.7 x 10/sup -12/t/sup 3/). An anomalous expansion was noted in the temperature range 1000 to 1500 deg C. Above 2500 deg C the rapid vaporization and crystal growth of UO/sub 2/ necessitate the application of heating techniques which provide rapid h… more

The Removal of Corrosion Scale From Heat Exchanger by Chemical Treatments

Description: disintegrating a corrosion scale from stainless steel systems without attacking the stainless steel. In this investigation particular sample of stainless steel corrosion scale appeared to be disintegrated most effectively in a solution of the trisodium salt of N-hydroxyethylethylenediaminetriacetic acid (Versenol) and ammonium acetate. In a subsequent test with this solution in a REED dynamic Ioop a considerable disintegration of scale from the loop was observed. in this test after a period of … more

High-Precision Determinations by Means of High-Absorbancy Spectro- Photometric Method. Application to the Determination of Cobalt in Aluminum

Description: High-absorbancy spectrophotometry was applied to the precise determination of about 0.15% cobalt in aluminum by the 1-(2-pyridylazo)-2- naphthol method. The absorbancies of sample aliquots were measured versus a standard containing 50 mu g of cobalt. The relative concentration error for a single measurement, assuming a 1% transmittancy error, is 0.93% and the coefficient of variation of 5 cobalt determinations is 0.5%. (auth)

Direct Spectrophotometric Determination of Uranium in Cyclohexane Solutions of Tri-n-Octylphosphine Oxide

Description: A method for the direct determination of uranium in a cyclohexane solution of tri-n-octylphosphine oxide (TOPO) is presented. The adduct, UO/sub 2/ Cl/sub 2/ x 2TOPO, that is formed when uranium(VI) is extracted from hydrochloric acid solutions by tri-n-octylphosphine oxide absorbs light in the ultraviolet region. This absorbance is measured at 230 m mu vs. a TOPO-cyclohexane solution that was contacted with hydrochloric acid of the same concentration as that in the test aliquot. The molar abso… more

Diffusion of Radioactive Gases Through Power Reactor Graphite

Description: Results of a study concerned with the problem of retarding the diffusion of fission products through unclad graphite fuel elements are presented. The pertinent parameters are pointed out, and their relations with the properties of graphite and gas coolants are considered. The effects of parameter variation on the concentration in the reactor primary system and the fission-product diffusion rate into the primary system are also examined. (J.R.D.)

AN AUTOMATIC GAS CHROMATOGRAPH FOR MONITORING OF REACTOR FUEL FAILURES. PART I. DESIGN

Description: A device was developed for detecting the failure of a fuel element in a reactor by monitoring for the presence of gaseous fission products. Small amounts of gaseous fission products were detected in the presence of radioactive argon by separating the fission product gases from the argon by chromatography. An automatic sequencing device was provided for taking samples at short intervals to ensure rapid detection of failures. (auth)
