Dear Sir or Madam:

By Reference 1, Indiana Michigan Power Company (I&M) proposed to amend Appendix A, Technical Specifications (TS), to the Donald C. Cook Nuclear Plant (CNP) Unit 2 Facility Operating License, DPR-74. A&M requested NRC approval to adopt a new analysis of a postulated large break loss-of-coolant accident (LBLOCA) for CNP Unit 2, and proposed to modify the associated TSs. By Reference 2, I&M provided a response to an NRC Request for Additional Information (RAI) regarding the proposed amendment. Enclosure 5 of Reference 2 provided a revision of the mark-up of TS Page 5.6-3 originally transmitted by Reference 1. This letter transmits a mark-up of TS Page 5.6-3 with an additional change such that it refers to the expected amendment number and provides a location for the amendment date. Enclosure 1 to this letter provides an affirmation statement. Enclosure 2 provides the mark-up of TS Page 5.6-3.
