This book was released on 1962 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instrumented, temperature-controlled irradiation capsules are being operated in the vertical fuel tubes of the CP-5 test reactor. The fuel tubes were modified in order to divert reactor coolant into the tubes to cool the capsules, and the shield plugs were revised to accommodate the capsule assemblies. Fuel materials and structural materials were successfully irradiated for periods in excess of one year. A description is included of the present capsule and assembly, the method of temperature control and instrumentation, and performance characteristics of the capsules.

Book excerpt: Instrumented capsule irradiations were performed with uranium-20 wt.% plutonium-10 wt.% fissium compositions sodium bonded to various high-temperature jacketing alloys. The specimens were EBR-II-diameter fuel rods that had been reduced to a 51-mm fuel length with jacketing of various alloys. A total of 78 specimens were irradiated over a temperature range of 420 to 900 degrees C and burnups of 1.2 to 4.2 at.% heavy metal. It was found that the rupture strength of the jacketing materials is not the only criterion of the restraint characteristics of the jacket during irradiation. The optimum relationship appears to be a jacket that retains high rupture strength with a high degree of ductility. The lifetime of the fuel specimens before failure occurred was also significantly extended by increasing the void space within the jacket.

Download or read book Effects of Irradiation on Thorium and Thorium uranium Alloys written by J. H. Kittel and published by . This book was released on 1963 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three separate irradiation experiments were completed with Th and Th-U alloys. In the first experiment, three-rolled plates of Th and Th-5 wt% U alloy irradiated to total atom burnups up to 1.5% at 200 deg C showed no anisotropic growth and decreased in density at a rate of 1% per wt.% burnup. In the second experiment, 15 swaged specimens of Th and of the alloys Th-0.1 wt% U, Th-1.4 wt% U, and Th-5.5 wt% U were irradiated to burnups ranging from 0.3 to 3.6% of all atoms at temperatures in the range of 45 to 200 deg C. Again, no anisotropic growth was observed and densities decreased at rates near 1% per wt.% burnup. A Th-1.4 wt% U alloy specimen with 2.0 wt.% burnup was found to have retained significant room-temperature ductility. In the final experiment, a group of 44 chill-cast specimens of Th alloys containing 10, 15, 20, 25, and 31 wt% U were irradiated to burnups ranging from 0.16 to 10.1% of all atoms. Maximum irradiation temperatures ranged from 260 to over 1000 deg C. Surface roughening occurred in the alloys containing 25 and 31 wt% U. Volume increases at any given temperature for all alloys were linear with increasing burnup. The rate of volume increase for all alloys rose from approximately 1% per wt.% burnup at the lower temperatures to a value of 2.5 at 650 deg C. Thereafter the swelling rate increased somewhat, reaching a value of 6% volume increase per wt.% burnup at 800 deg C. The rates of volume increase under irradiation of Th-U alloys in the entire temperature range studied were significantly less than those reported for the best U-base alloys. It is suggested that the excellent resistance to high- temperature swelling of the cast Th-U alloys resulted from the fact that a dispersion of very thin U particles was obtained. A high probability, therefore, existed for fission recoils to escape from the U particles into the isotropic and less densely packed Th matrix.

Download or read book A Shielded Enclosure for Neutron Radiographic Inspection of Encapsulated Irradiated Specimens written by W. N. Beck and published by . This book was released on 1964 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A neutron shield enclosure for neutron radiographic inspection of encapsulated, irradiated fuel specimens has been fabricated. An existing shielded cask was modified to handle a complete irradiation experiment from the CP-5 reactor. The inspection technique makes use of a potentially radioactive screen to detect the neutron imaging beam after it has passed through the inspection object. The radioactive image on the screen is made visible by allowing it to decay in close contact with photographic film. Contrast resolution of the system is 0.76 mm or better. Contrast sensitivity is in the order of 1 to 2 percent.
