Donald C. Cook Nuclear Plant Units 1 and 2 TECHNICAL SPECIFICATION CHANGE REQUEST; REVISE THE TRAIN A/B BATTERY PROFILES AND MODIFY TRAIN N BATTERIES'ROFILE REQUEST FOR MODIFICATION

\

The purpose of this letter is to modify our AEP:NRC:0896S letter, same subject, dated July 19, 1994, as requested by the NRR staff.

In a January 13, 1995, telephone conference the NRR reviewing.

engineer requested that we adopt the language of the latest revision to IEEE Standard 450 with regard to the modified performance test and degraded performance test recommendations. To satisfy his request, paragraph "e" on pages 3/4 8-14 and 3/4 8-18 for the Donald C. Cook Nuclear Plant Units 1 and 2 technical specifications respectively should read as follows.

"At least once per 60 months, conduct a performance test of battery capacity during shutdown (MODES 5 or 6), by verifying

.that the battery capacity is at least 80% of the manufacturer's rating. When this test is performed in place of a battery service test, a modified performance test shall be conducted.

Annual performance tests of battery capacity shall be given to any battery that showssigns of degradation or has reached 85% of the service life expected for the application.

Degradation is indicated when the battery capacity drops more than 10% from its capacity on the previous performance test, or is-below 90% of the manufacturer's rating. If the battery has reached 85% of service life, deliversa capacity of 100%

or greater of the manufacturer's rated capacity, and has shown no signs of degradation, performance testing at two year intervals is acceptable until the battery shows signs of degradation."

. ~ 0 U. S. Nuclear Regulatory Commission AEP:NRC:0896U Page 2 The battery surveillance requirements have been modified to reflect the comments as requested. For your convenience, a copy of the existing T/Ss, marked to reflect all the changes, is included as ~ Attachment 2 is a typed copy of the T/Ss, as they should appear, with bar margins indicating the changes. Please note the new format we are implementing to allow electronic access to the T/Ss. With the new format there are pagination changes and minor administrative changes to Table 4.8-2 in both units in an ongoing effort to achieve uniformity between the units.

We have reviewed the staff's requested changes and believe the significant hazards consideration performed pursuant to 10 CFR 50.92 for the original submittal is valid. Therefore, we have not provided further justification for the changes requested by the NRR staff.

We believe the proposed additional changes will not result in (1) a significant change in the types of effluent or a significant increase in the amount of any effluent that may be released offsite, or (2) a significant increase in individual or cumulative occupational radiation exposure.

These proposed T/S changes have been reviewed and approved by the Plant Nuclear Safety Review Committee and will be approved by the Nuclear Safety and Design Review Committee at the next regularly scheduled meeting.

In compliance with the requirements of 10 CFR 50.91(b)(l), copies of this letter and its attachments have been transmitted to Mr. J. R. Padgett of the Michigan Public Service Commission and the Michigan Department of Public Health.
