A variety of high uranium density (uranium molybdenum alloy based) research reactor fuels are being irradiated in the Advanced Test Reactor at the Idaho National Laboratory. The RERTR-7A, -7B, and -8 experiments will consist of three test trains containing 66 miniplates of various fuel meat compositions that will be subjected to  near prototypical reactor environment. The RERTR-7A and 7B experiments will explore the influence of modified matrix materials (RERTR-7A) and fuel alloys (RERTR-7B) on fuel/matrix chemical interaction. The three experiments will also contain a number of monolithic type fuel plates that will substantially expand their irradiation performance database. The modified matrix materials include 6061-Al, 4043-Al, Al-0.5 Si, Al-2.0Si, and Mg. The modified fuel alloys used in RERTR-7B will include small amounts of Zr or Ti alloyed with the U-Mo fuel. The plates in RERTR-7A and 7B will be operated with peak surface heat flux, surface temperature, centerline temperature, and burnup of approximately 350 W/cm2, 200C, 250C, and 70% LEU equivalent, respectively. The RERTR-8 experiment will expose 16 plates to a short (15 day) high power irradiation cycle. The RERTR-8 test train will consist of one capsule (eight miniplates) removed from the RERTR-7B experiment following one irradiation cycle and one fresh capsule (eight miniplates). The capsules will be irradiated for one additional ATR cycle (~50 days) prior to the high power cycle. The peak surface heat flux in the RERTR-8 experiment will be on the order of 550 W/cm2.
