In order for long-range autonomous robots to be successful they must be able to maintain accurate information about their location, available resources, and the state of critical components. We propose here a methodology which incorporates traditional, sensor-based tracking methods with discrete probabilistic representations of system state. Further, we extend the...
Five U.S. high performance research reactors (HPRRs) are currently part of an international nonproliferation program with the objective of ultimately converting their highly enriched uranium (HEU) fuel to a new high density, low enriched uranium (LEU) fuel while still maintaining their reactor kinetic and thermal hydraulic performance. A uranium-molybdenum (U-Mo)...
Oregon State University has recently conducted a complete core conversion analysis as part of the Reduced Enrichment for Research and Test Reactors Pprogram. The goals of the thermal hydraulic analyses were to calculate natural circulation flow rates, coolant temperatures and fuel temperatures as a function of core power for both...
The Advanced Test Reactor (ATR) is conducting
scoping studies for the conversion of its fuel from a
highly enriched uranium (HEU) composition to a low-enriched
uranium (LEU) composition, through the
Reduced Enrichment for Research and Test Reactors
Program, within the Global Threat Reduction Initiative.
These studies have considered a wide...
