Cesium chloride compatibility testing program. Annual report, fiscal year 1985

Description: At Hanford, fission product cesium, containing 20 to 40% /sup 137/Cs, has been recovered from the high-level waste (HLW) and converted to cesium chloride (CsCl). Recovery of the Cs, as a nitrate, from the HLW and its subsequent purification, takes place in B-Plant. Conversion of the purified product to CsCl, encapsulation of the CsCl, and water storage of the CsCl capsules takes place in the Waste Encapsulation and Storage Facility (WESF). The CsCl is doubly encapsulated in high-integrity 316L … more

Materials Science Division coal technology seventh quarterly report, April--June 1976. [Gasification plant materials]

Description: Preliminary analysis of test results of 15 ceramic refractories for slagging gasifiers indicates that the magnesia-chrome, chrome-bonded alumina, and fusion-cast spinel bricks have substantially better abrasion-corrosion resistance than the other compositions. Thermal-shock testing has indicated that resistance to spalling of ceramic coatings can be improved with the use of graded alumina-chromia and magnesia-alumina multilayer coatings. The first corrosion-erosion test run for a total of 100-h… more

Coal Technology Program. Progress report for December 1977

Description: In the pressure vessel and piping materials work, the report, ''Assessment of Materials Technology for Gasifer and Reaction Pressure Vessels and Piping for Second Generation Commercial Coal Conversion Systems'' (ORNL-5238), has been submitted for publication and distribution. Impact and tensile teting is under way on 2/sup 1///sub 4/ cr-1 Mo steel which has received a simulated quench, temper, and postweld heat treatment. Two topical reports on coating inspection have gone to reproduction. CoCr… more

Some recent observations on the radiation behavior of uranium silicide dispersion fuel

Description: Addition of B{sub 4}C burnable poison results in higher plate swelling in both U{sub 3}Si{sub 2} and U{sub 3}Si-Al dispersion fuel plates and also decreases the blister threshold temperature of these plates. Prolonged annealing of U{sub 3}Si{sub 2}-Al fuel plates produced no blister after 696 hours at 400{degrees}C. Blister formation started between 257 hours and 327 hours at 425{degrees}C and between 115 hours and 210 hours at 450{degrees}C. Operation with breached cladding resulted in pillowi… more

Materials technology for coal-conversion processes. Eleventh quarterly report, April--June 1977

Description: Silicon-carbide refractories with various bond systems exposed to molten slag at 1500/sup 0/C for 500 h in Run 4 showed virtually no attack. The resistance of the silicon carbide to slag attack is attributed to large thermal fluxes induced by water-cooled chills applied to the cold faces. Magnesia-chromia refractories exposed to molten slag at 1500/sup 0/C for 500 h in Run 5 were somewhat less resistant to slag attack than the silicon-carbide refractories. In-situ erosive-wear measurements on t… more

Correlation of waterside corrosion and cladding microstructure in high-burnup fuel and gadolinia rods

Description: Waterside corrosion of the Zircaloy cladding has been examined in high-burnup fuel rods from several BWRs and PWRs, as well as in 3 wt % gadolinia burnable poison rods obtained from a BWR. The corrosion behavior of the high-burnup rods was then correlated with results from a microstructural characterization of the cladding by optical, scanning-electron, and transmission-electron microscopy (OM, SEM, and TEM). OM and SEM examination of the BWR fuel cladding showed both uniform and nodular oxide … more
