Fuel element swelling problems have been experienced in the high-exposure fuel irradiation program in C Reactor, In an effort to determine the mechanism responsible for this swelling, three elements from C Reactor, one of which was a ruptures, were sent to the Radiometallurgy Laboratory for visual and metallographic examination. Because the swelled fuel was not numbered as to column position, the exact position of the examined elements is not known but they were believed to have come from the center of the charge and therefore exposures for these individual elements will be 25--50% higher than the column average exposures. This percentage figure was determined from data from nine tubes of C2N fuel which exhibited swelling. These nine tubes operated under nearly the same conditions as the examined elements. Maximum core temperatures for the examined elements are believed to be between 300--340C. The mechanisms for swelling were different in the high and low-exposure fuels. The high-exposure fuel exhibited grain-boundary tearing along a wide circumferential band over the entire transverse section of the fuel examined. The areas near the OD and ID were relatively free from tearing. The low-exposure fuel showed no grain boundary tearing but it did contain angular voids in …

Abstract: A definitive investigation of the boron-carbon equilibrium system is being made by X-ray diffraction, metallographic, and thermal analytical techniques. On the basis of metallographic and X-ray diffraction studies it is concluded that boron carbide has a range of solubility from approximately 10 to 20 atomic per cent carbon at 1500 degrees to 2000 degrees Celsius. The melting point of the carbide-graphite eutectic has been established as 2325-2350 degrees Celsius. No reversible allotropy of the beta-rhombohedral structure has been observed. The solubility of carbon in boron is very small. The melting point of dilute carbon alloys is found to be essentially the same as that of pure boron (2040 degrees to 2050 degrees). No metallographic evidence of a three-phase reaction of dilute alloys is observed.

This report itemizes the irradiations performed by Testing for Battelle-Northwest Laboratories. It lists the material being irradiated, awaiting disposition and material shipped during the report period.

The objectives of this production test are to confirm the KVNS fuel element design, determine the effect of support height on annulus coolant temperature distribution (R Value), evaluate the effect of eccentricity on KVNS fuel element irradiation behavior.

Abstract: This technical report summarizes all core physics experiments performed on SM-1 Core I and SM-2 Rearranged and Spiked Core I throughout core life. These measurements were obtained on site during the 16.4 MWYR lifetime of SM-1 Core I and 1.6 MWYR lifetime of SM-1 Rearranged and Spiked Core I. SM-1 Core I was the first stainless steel - UO2 dispersion core to burn out in the Army Nuclear Power Program. Experimental techniques are described and a complete history of fuel movements in the core presented. Measurements include control rod bank positions during all core conditions, temperature and pressure coefficients, control rod calibrations, transient poison effects, source multiplication, and stuck rod positions. The effect of core rearrangement and spiking on core reactivity and core life is also reported. Applicable measurements from the SM-1 zero power experiments are included.
