SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE COOPER NUCLEAR STATION LICENSE RENEWAL APPLICATION (TAC NOS.

MD9763 AND MD9737)

Dear Mr. Minahan:

The purpose of this letter is to transmit the request for additional information (RAI) B.1.20-1 which was inadvertently left out of the previous RAI letter dated June 30, 2009 (ML091600284),

and it is considered as a part of that letter. The staff has identified, in the enclosure, areas where this additional information is needed to complete the review of the Cooper Nuclear Station license renewal application.

This item in the enclosure was discussed with Mr. David Bremer. If you have any questions, please contact Emmanuel Sayoc at 301-415-1924 or by e-mail at emmanuel.sayoc@nrc.gov, or Tam Tran at 301-415-3617 or by e-mail at tam.tran@nrc.gov.

Sincerely,

/RA/

Tam Tran, Project Manager Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket No. 50-298

ENCLOSURE RAI B.1.20-1

Background:

There have been reoccurring failures of main steam line pipe supports at CNS since the 1980's.

In 2006 a Condition Report (CR-CNS-2006-09590, Action Item 8) was initiated to address the recurring pipe support deficiencies with completion of all redesign and associated hardware changes (if necessary) by June 30, 2011.

Issue:

Continued failures of steam line supports during each period of operation between plant outages can affect the structural integrity of the main steam line piping system.

Request:

Explain how the corrective action process will address the potential aging effects (i.e. structural fatigue) on the piping system due to the unanalyzed loading condition associated with the past pipe support failures.
