Book excerpt: Reported radioactivity in the Low-Intensity Test Reactor (LITR) water coolant traceable to uranium contamination on the surfaces of the alclad uranium-- aluminum plate-tyne fuel element led to an investigation to determine the sources of uranium contamination on the fuel plate surfaces. Two possible contributors to surface contamination are external sources such as rolling-mill equipment, the most obvious, and diffusion of uranium from the uranium-aluminum alloy fuel into the aluminum cladding. This diffusion is likely because of the 600 deg C heat treatments used in the conventional fabrication process. Uranium determinations based on neutron activation analysis of machined layers from fuel plate surfaces showed that rolling-mill equipment, contaminated with highly enriched uranium, was responsible for transferring as much as 180 ppm U to plate surfaces. By careful practice where cleanliness is emphasized, surface contamination can be reduced to 0.6 ppm U/sup 235/. The residue remaining on the plate surface may be accounted for by diffusion of uranium from the fuel alloy into and through the cladding of the fuel plate. Data obtained from preliminary diffusion studies permitted a good estimate to be made of the diffusion coefficient of uranium into aluminum at 600 deg C: 2.5 x 10/sup -8/ cm//sec. To minimize diffusion while the plate-type aluminum-base research reactor fuel element is being processed, heat treatments at 600 deg C should be limited to 2.5 hr. The uranium contamination on the surfaces of the finished fuel plates should then be less than 0.6 ppm U / sup 235/ . This investigation also revealed that the solubility limit of uranium in aluminum at 600 deg C is approx 60 ppm. (auth).

Book excerpt: Irradiation tests of an aluminum-alloy-clad aluminum -uranium alloy- fueled plate were discontinued due to cladding failure after a maximum burnup of 58%. Cause of the failure was local corrosion of the aluminum alloy. Swelling was observed which was attributed to the combination of high burnup and high fuel temperatures.

Book excerpt: To be published in TID-7642, Proceedings of the Research Reactors Fuel Element Conference held in Gatlinburg, Tenn., Sept. 17-19, 1962. Irradiation experiments have been made to determine the irradiation temperature and burnup limits ior X8001 aluminum alloy-clad Al-17.5 wt % U-2 wt % Ni-0.5 wt % Fe alloy silicon-bonded plates of the type developed ior the SL-1 reactor. The irradiations were conducted on prototype SL-1 plates both in MTR capsules and in the ANL-2 High Pressure Water Loop in the MTR. The loop experiments were conducted under local boiling conditions in water at 215 deg C (420 deg F) flowing at 12 ft/sec. One of the plates being irradiated in the loop developed a clad defect after a period of operation in high pH water. At the time of clad penetration the plate had achieved a burnup of 58 percent of the uranium (1.3 percent of total fuel alloy atoms). No catastrophic corrosion of the fuel alloy or extensive fission product release occurred when the plate was irradiated with the defect. Because of heavy scale deposition on the loop specimens fuel alloy temperatures were calculated to be as high as 560 deg C (1040 deg F). Fuel swelling occurred above temperatures near 450 deg C (840 deg F). The silicon bonding technique appeared to be highly effective in maintaining sound metallurgical bonds between fuel and cladding.
