The driver elements for the fourth core of the OMRE will consist of uranium-molybdenum alloy fuel plates clad in finned aluminum. In addition, the core will contain experimental uranium metal aluminum-clad plate-type elements and UO/sub 2/-APM pin-type elements. Since previous OMRE cores have been fueled primarily with highly enriched UO/sub 2/stainless steel cermet-type fuel elements, this core represents a substantial change in design and composition. Therefore, complete steady-state performance analyses and transient accident analyses were performed for it and are reported herein. The analyses show that for any protected accident, the worst result is attainment of a maximum fuel surface temperature which is limited by nucleate boiling to a value between 900 and 1070 deg F, depending on the amount of nitrogen and/or water dissolved in the coolant. The minimum burnout ratio is greater than two in every case. (auth)
