Title	Part 21 - Burnable Poison Rod Assembly Misload
Event Description	The following is a synopsis of information provided by Framatome, Inc. (Framatome) via email: During startup testing at the affected plant, unexpected high reactor peaking factor readings resulted from an incorrect boron concentration of Al2O3-B4C pellets in two burnable poison rod assemblies (BPRAs). The cause of the issue was due to 0.2 percent boron concentration Al2O3-B4C pellets inadvertently combined with the intended 2.0 percent boron concentration Al2O3-B4C pellets, which were then placed back into inventory labeled as 2.0 percent. This issue was determined to be a 10 CFR 21 Defect on June 21, 2024. Corrective actions are that Framatome replaced the two affected BPRAs with BPRAs fabricated correctly and a root cause analysis has been initiated by Framatome which is scheduled for completion by July 31, 2024. The affected plant is Oconee Unit 3. The name and address of the individual reporting this information is: Gayle Elliott Director, Licensing & Regulatory Affairs Framatome Inc. Office 434 832-3347 Mobile 434 841-0306 3315 Old Forest Road Lynchburg, VA 24501 gayle.elliott@framatome.com
