Amy, Attached is the Draft RAI concerning the Prairie Island Alternative Source Term (AST) Steam Generator Tube Rupture Margin-to-Overfill (SG MTO) analysis. As we discussed, this Draft RAI supersedes the Draft RAI (Reactor Systems Branch [SRXB] questions) I sent to you on September 21, 2010. The Containment and Ventilation Systems Branch [SCVB] question from the 9/21/2010 RAI is unchanged.

Please review the RAI and let me know if youd like to have a clarifying teleconference with the NRC staff to discuss this Draft RAI. Lets also discuss the timing for Prairie Islands response to these RAIs.

Please call me if you have any questions.

Regards, Tom Wengert USNRC Project Manager NRR/DORL/LPLIII-1 (301) 415-4037 E-mail Properties Mail Envelope Properties ()
