Enclosure MONTICELLO NUCLEAR GENERATING PLANT LICENSE RENEWAL APPLICATION (LRA)

REQUEST FOR ADDITIONAL INFORMATION (RAI)

RAI B2.1.2-1 In lieu of the ASME Section XI examination requirements described in the GALL Report for the Reactor Vessel Stabilizer Bracket attachment welds (Examination Category B-K for welded attachments for vessels, piping pumps and valves), MNGPs current relief request allows visual examination of the accessible areas of those welds to provide adequate aging management during the extended period of operation. The NRC staff considers this an exception to the GALL Report for the ASME Section XI In-Service Inspection, Subsection IWB, IWC, and IWD Program. MNGP completed a VT-3 examination of the accessible areas of those welds during the 2005 refueling outage with no reportable indications recorded.

To support the NRC staff evaluation, the applicant is requested to describe details of the type of weld that is used for this attachment. Describe applicable examination requirements at the time of vessel manufacture (when the attachments were welded to the vessel) and, if readily available, provide applicable examination results. Describe inspections or examinations, if any, of the welds that have been performed since initial start-up of the plant, including the inspection or examination methodology and available results. Describe stressors (or absence thereof) that are experienced by the welds (e.g. mechanical or thermal forces, fatigue) during normal operation, and state, based on MNGPs operating history, whether the welds have experienced stressors different from the normal operating stressors. Provide a summary of industry operating experience, to the extent known by the applicant, that is related to failures or indicated defects in similar welds or to successful examination of similar welds. Provide any other additional information that MNGP considers appropriate for the NRC staff to consider in its evaluation of this proposed exception to the GALL Report's description for the ASME Section XI ISI, Subsection IWB, IWC, and IWD AMP.
