Dear Sir or Madam:

By Reference 1, Indiana Michigan Power Company (I&M), the licensee for Donald C. Cook Nuclear Plant (CNP) Units 1 and 2, proposed to amend Facility Operating Licenses DPR-58 and DPR-74.

I&M proposed to modify Technical Specifications (TS) to adopt NUREG-1431, Revision 3, "Standard Technical Specifications, Westinghouse Plants," (STS) wording in TS 3.3.1, Reactor Trip System (RTS) Instrumentation, and TS 3.3.2, Engineered Safety Feature Actuation System (ESFAS)

Instrumentation, for plants with installed bypass test capability.

Ao-.o

U. S. Nuclear Regulatory Commission AEP;NRC:7331-05 Page 2 I&M has installed the first stage of a modification for bypass test capability in Unit 1 and Unit 2 for some TS Functions other than those for the Nuclear Instrumentation System (NIS). Bypass test capability for NIS Functions was planned for the second stage of the modification. I&M no longer plans to install the second stage in either unit and is withdrawing this portion of the license amendment request, as discussed below.

I&M has elected to withdraw the proposed changes to Unit 1 and Unit 2 TS 3.3.1, "Reactor Trip System Instrumentation," Condition C, Required Action C.1 Note. A list of TS Functions that had, or were planned to have, installed bypass test capability was provided in Reference 1, Enclosure 2, Section 2.0. This list remains valid with the exception of TS 3.3.1, Function 2, Power Range Neutron Flux, and Function 3, Power Range Neutron Flux - High Positive Rate, which are the TS Functions for which I&M no longer plans to install bypass test capability. Therefore, the proposed changes that are withdrawn are those documented in Reference 1, Attachments IA through 2B, TS 3.3.1, Condition C, Required Action C.1 Note, on Page 3.3.1-1 of both the Unit I and Unit 2 TS.

The enclosure provides an affirmation affidavit pertaining to this letter.

Copies of this letter and its enclosure are being transmitted to the Michigan Public Service Commission and Michigan Department of Environmental Quality in accordance with the requirements of 10 CFR 50.91.

This letter contains no new or revised regulatory commitments. Should you have any questions, please contact Ms. Susan D. Simpson, Regulatory Affairs Manager, at (269) 466-2428.
