PART 21 NOTIFICATION RELATED TO THE XL-S96 CPR CORRELATION FOR SVEA-96 FUEL

"The purpose of this letter is to notify the Nuclear Regulatory Commission of a defect as defined in 10 CFR 21, 'Reporting of Defects and Noncompliance.' The defect concerns the XL-S96 Critical Power Ratio (CPR) correlation for ABB SVEA-96 fuel assemblies for Boiling Water Reactors (BWRs). Specifically, the defect concerns the XL-S96 CPR correlation, which is based solely on a cosine axial power shape. The defect could lead to non-conservative Operating Limit MCPRs and monitored CPRs for top-peaked axial power shapes.

"The Enclosure summarizes the evaluation performed by ABB Combustion Engineering (ABB-CE). If you have any questions, please feel free to contact me [Ian C. Rickard] or Mr. Virgil Paggen of my staff."

This event effects WNP-2 current operating cycle (Cycle 14).
