Nuclear plants strive to prevent the intrusion of foreign materials into the reactor coolant system (RCS). When these foreign material controls reveal that a foreign object might be lost in the RCS, plant personnel take exhaustive measures to locate and remove the lost object. When that fails, the plant resorts to evaluating the potential effects of the lost object on critical components, including fuel. This evaluation could lead to setting lower operating limits for the most susceptible fuel bundles in a boiling water reactor (BWR) core. A cross-disciplinary team at Constellation Nuclear Fuels developed advanced analytics to determine whether certain operating limit penalties for BWR fuel bundles in the periphery of the core could be eliminated in this scenario. The penalties are applied to ensure that a potential flow blockage due to lost parts assumed to be in the reactor coolant system would not threaten the integrity of fuel rods in peripheral bundles. The analytics substantiated that the penalties could be removed, and the approach was piloted successfully at the Limerick plant. Constellation is now applying this approach to other BWRs in the Constellation fleet.
