Monticello Nuclear Generating Plant - Draft Requests for Additional Information re: Request RR-003 (TAC No. MF3050)
Dear Mr. Rippy:
By letter to the U.S. Nuclear Regulatory Commission (NRC) dated October 31, 2013 (Agencywide Documents Access and Management System Accession No. ML13308A390), Northern States Power Company - a Minnesota corporation (NSPM), doing business as Xcel Energy, submitted Request RR-003. In RR-003, NSPM requests authorization to implement a risk-informed/safety-based inservice inspection (ISI) program based on American Society of Mechanical Engineers (ASME) Boiler and Pressure Code Case N-716, "Alternative Piping Classification and Examination Requirements,Section XI, Division 1," for ASME Class 1 and 2 piping welds for the fifth 10-year ISI interval at the Monticello Nuclear Generating Plant.
The NRC staff in the Component Performance, NDE, and Testing Branch of the Office of Nuclear Reactor Regulatory has identified areas where additional information is needed to complete its review. Draft requests for additional information (RAI) are provided below.
You may accept these draft RAIs as formal Requests for Additional Information and provide a response by May 9, 2014. You may also request to discuss the contents of these draft RAIs with the NRC staff in a conference call.
