Fuel Defect Localization Using Delayed Neutron Monitoring System Bruce A 2011 to 2013
34th Annual CNS Conference - 2013 June 09-12

The delayed neutron monitoring system (DNMS) is the primary system used to locate defective fuel bundles in reactors on the Bruce site. Recent system upgrades at Bruce A and the refurbishment and restart of two reactor units have created minor challenges. The data analysis methods used for Units 3 to 8 could not be directly applied to the scan data from the refurbished units due to lack of historical data and initial scans being performed after fuel defects were present in the cores. Work continues to better utilize the DNMS data to locate channels containing defect fuel.
