In Reference 1, DTE Electric Company (DTE) submitted relief request RR-A37, Revision 1, for the third 10-year interval of the Fermi 2 Inservice Inspection (IS I)
Program. The subject revised relief request involves implementation of ASME Code Case N-702, "Alternative Requirements for Boiling Water Reactor (BWR) Nozzle Inner Radius and Nozzle-to-Shell Welds,Section XI, Division 1." Code Case N-702 stipulates that VT-1 examination may be used in lieu of the volumetric examination for the Reactor Pressure Vessel (RPV) nozzle inner radius section (ASME Code, Category B-D, Item B3.100).
As a supplement to relief request RR-A37, Revision 1, DTE will utilize ASME Code Case N-648-1, "Alternative Requirements for Inner Radius Examination of Class 1 Reactor Vessel Nozzles,Section XI, Division 1," with associated required Regulatory Guide 1.147 conditions if VT-1 examinations are performed in lieu of volumetric examinations.
No new commitments are being made in this submittal.
