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.

Book excerpt: A series of experiments was designed to assess the suitability of uranium-molybdenum alloys as high-temperature, high-burnup fuels for advanced sodium cooled reactors. Specimens with molybdenum contents between 3 and 10% were subjected to capsule irradiation tests in the Materials Testing Reactor, to burnups up to 10,000 Mwd/MTU at temperatures between 800 and 1500 deg F. The results indicated that molybdenum has a considerable effect in reducing the swelling due to irradiation. For example. 3% molybdemum reduces the swelling from 25%, for pure uranium. to 7% at approximates 3,000 Mwd/MTU at 1270 deg F. Further swelling resistance can be gained by increasing the molybdenum content, but the amount gained becomes successively smaller. At higher irradiation levels, the amount of swelling rapidly becomes greater, and larger amounts of molybdenum are required to provide similar resistance. A limit of 7% swelling, at 900 deg F and an irradiation of 7,230 Mwd/ MTU, requires the use of 10% Nonemolybdenum in the alloy. The burnup rates were in the range of 2.0 to 4.0 x 10p13s fissiom/cc-sec. Small ternary additions of silicon and aluminum were shown to have a noticeable effect in reducing swelling when added to a U-3% Mo alloy base. Under the conditions of the present experiment, 0.26% silicon or 0.38% aluminum were equivalent to 1 to 1 1/2% molybdenum. The Advanced Sodium Cooled Reactor requires a fuel capable of being irradiated to 20,000 Mwd/MTU at temperatures up to 1500 deg C in metal fuel, or equivalent in ceramic fuel. It is concluded that even the highest molybdenum contents considered did not produce a fuel capable of operating satisfactorily under these conditions. The alloys would be useful, however, for less exacting conditions. The U-3% Mo alloy is capable of use up to 3,000 Mwd/MTU at temperatures of 1300 deg F before swelling becomes excessive. The addition of silicon and aluminum would increase this limit to at least 3,000 Mwd/MTU, and possibly more if the

The fuel was duplex melted and given a homogenizing heat treatment prior to assembly into extrusion billets. The rods were prepared by co-extruding the fuel alloy in Zircaloy-2 cups, then drawing the rods to size. (auth).
