Chloride Deposition From Steam Onto Superheater Fuel Clad Materials

Description: Experimemts using Cl/sup 36/ in a steam test loop were conducted to study the deposition behavior of chlorides on BONUS superheater fuel assembly materials. The moisture content of the steam was varied between 0 and 0.5 wt%, and superheat was added up to 15 deg F before the steam passed over the test cartridge heater. The effects of vaiiables on the chloride deposition on the heater were studied in detail. Chloride deposition from moist steam was found to result in heavy, adherent deposits whic… more

INSTRUMENT FOR DETERMINING CRUSHING STRENGTH OF PARTICLES

Description: An instrument for crushing-strength determinations of uncoated and pyrolytic-carbon-coated fuel particles (50 to 500 mu in diameter) was developed to relate the crushing strength of the particles to their fabricability. The instrument consists of a loading mechanism, load cell, and a power supply-readout unit. The information that can be obtained by statistical methods of the data analysis is illustrated by results on two batches of fuel particles. (auth)

Investigation of Thermal-Stress-Fatigue Behavior of Stainless Steels. Quarterly Progress Report No. 4, October-December 1962

Description: The thermal-stress-fatigue and strain-cycling-fatigue testing of Types 304 and 304-L stainless steels are discussed. The test variables included atmospheric surroundings, hold time, specimen size, and mean temperature. Results indicated a significant difference in fatigue life between annealed and cold-worked material. No significant difference in fatigue life resulted from testing in argon as opposed to air. Metallographic structural analysis showed the effects of strain softening as well as v… more

Corrosion Characteristics of the Rare Earth and Yttrium Metals

Description: The corrosion of rare earth metals in air, water, and aqueous solutions at different temperatures was measured by conventional weight-loss and weight- gain tests. The metals oxidize slowly in air, corrode slowly in water and alkaline solutions, and are readily soluble in most acids. Correlations of corrosion behavior with the electronic and physical properties of the rare earths are discussed. (auth)

IN-PILE RADIATION CORROSION EXPERIMENTS WITH ZIRCONIUM, TITANIUM, AND STEEL ALLOYS IN 0.17 m UO$sub 2$SO$sub 4$ SOLUTIONS AT 280 C

Description: In-pile loop experiments L-2-15 and L-4-16 were designed to test the radiation corrosion of Zircaloy-2 and other possible reactor construction materials in UO/sub 2/SO/sub 4/ solutions.

Post-Irradiation Evaluation of a Plate-Type UO$Sub 2$ Fuel Element

Description: The premature failure of fuel Element M22, which had six compartments of 0.100-in.-thick, 96% TD UO/sub 2/ + 6 wt% ZrO/sub 2/ fuel, was attributed to the large irradiation-induced solid volume swelling of the UO/sub 2/ fuels. This volume swelling was the result of incomplete homogenization during fabrication of the mixed and sintered U/sup E/O/sub 2/ and U/sup N/O/sub 2/ fuel s in Element M22. In addition, heavy hydriding of the Ni-free Zircaloy-2 cladding occurred in the relatively hot areas a… more

INVESTIGATION OF THERMAL-STRESS-FATIGUE BEHAVIOR OF STAINLESS STEELS. Quarterly Progress Report No. 6, April-JunE 1963

Description: A study was made of the effects of specimen size and grain size on thermal-stress-fatigue (TSF) behavior of stainless steels. The competing nature of failure by specimen instability and failure by fatigue was disclosed and shown to be a complex problem. It was shown also that conventional fatigue results and TSF results conform for 304-L stainiess steel for the variables studied. The testing of 304 and 304-L austenitic stainless steels, was essentially completed. The variables investigated in T… more

Electron Beam Melting of Uranium

Description: Feed stock prepared from ingot, dingot, and under-saltmelted U was melted by electron bombardment. Analysis of the ingots produced revealed that some Al, Cr, Mg, Mn, and Pb were volatilized from the melt. C was reduced when Zr was present in the feed material. H/sub 2/ and N/sub 2/ also were removed, the latter oniy when there was a relatively high concentration in the feed material. The work indicated the need for very slow melting rates or the casting of large diameter ingots for successful r… more

INVESTIGATIONS OF CARBIDES AS CATHODES FOR THERMIONIC SPACE REACTORS. Quarterly Progress Report for the Period Ending May 31, 1963

Description: Two long-term test cells were fabricated and tested. One was loaded with a 30 UC--70 ZrC sample and the other with a 90 UC--10 ZrC samrple. The rates of vaporization of these samaples in vacuum were determined both in the absence and in the presence of a Ni anode maintained at 983 deg K with an electrode spacirig of 20 mils, hr order to set the baseline values. Measurement of the rates of vaporization of these samples under these conditions in the presence of Cs vapor at a pressure of about 1.8… more

Development of a High Yield 90 Zr-10 U Alloy Massive Hydride

Description: Through addition of approximaely 0.4 wt % carbon (as zirconium carbide) to a 90 wt % Zr - 10 wt % U alloy, a 100% yield of uncracked massively hydrided fuel elements of high hydrogen density (N/sub/H ≈ 5.7 to 6.6) was obtained. The marked increase in yield was attirbuted t the presence of a carbide phase, serving as a nucleant and grain-growth inhibitor during solidification and subsequent solid-state transformations that occur during the hydriding process. The resulting hydride structure was f… more
