Specifically, as discussed in a conference call between NRC staff and ONC on June 16, 2008, ONC is providing an amended response to Question 3. Question 3 was included in the NRC request for additional information dated January 28, 2008.

NRC Question ONC references NEI 99-03, Revision 1, Appendix EE, in Attachment 1, Page 7 of 11 under I Exceptions.'
