D.C. Cook Unit 2 - A schedule in a 2/24/11 submittal supporting the large-Break LOCA amendment (TAC ME1017)
Joe I am responding to your e-mail (below).
The 90-day schedule stated in your 2/24/11 letter was not made into part of Amendment No.
297 (the large-break LOCA amendment). In fact, the associated safety evaluation did not even say that the staff found the proposed LBLOCA amendment acceptable based partly on the subject 90-day schedule. Thus, it is OK for you to change it the way you described in your e-mail, without invoking the amendment process.
Thank you for notifying me of this slight schedule change.

Subject:
CNP Unit 2 LBLOCA Analysis Peter, As we preliminarily discussed yesterday, Enclosure 9 to a February 24, 2011, I&M letter (ML110680210) informed the NRC of two errors in a new CNP Unit 2 LBLOCA analysis that was subsequently approved by the NRC (ML110730783, March 31, 2011). I&M stated that resolution of the errors would not alter the methodology used for the new analysis, and that it would provide the NRC a description of the resolution of the errors within 90 days of the date of the letter, i.e., by May 25, 2011. I&M also stated that it would inform the NRC Licensing Project Manager if there were significant changes to that schedule.
Although I&M has established a multi-discipline team and enlisted Westinghouse support, determination of the appropriate approach for resolving the one of the errors has proven to be more challenging that anticipated. As a result, I&M now expects that a description of its plan for resolution of the errors will be submitted no later than June 3, 2011.
Please let me know if you have any questions or concerns.
Thanks Joe Waters D. C. Cook Licensing
