NMP2 EPU - Supplemental RAIs RE: March 23, 2011 RAI Response Date: Thursday, April 14, 2011 8:56:00 AM

Theresa, The NRR technical staff has two additional questions following the review of the March 23, 2011 NMPNS RAI response letter. If necessary, we can have a conference call to discuss the questions for any clarification(s) needed, prior to NMPNS providing a formal response. Please respond to the below questions by May 15, 2011.

Supplemental CSGB-RAI-3.a On page 6 of Attachment 1of its letter dated March 23, 2011, the licensee states that, NMPNS does not intend to utilize these coupons [for the initial 10 Boral spent fuel racks] since the coupon tree was not installed at the same time as the associated racks. The NRC staff is uncertain whether the Boral material installed in 2001 has an effective surveillance monitoring program. Please provide the surveillance approach and testing for these 10 Boral spent fuel racks.

Supplemental CSGB-RAI-3.b On page 6 and 7 of Attachment 1 of its letter dated March 23, 2011, the licensee states that coupons will be evaluated for visual appearance and lists deterioration of coupon as one of the parameters being evaluated. Please discuss what is meant by deterioration and how it is evaluated.
