ATTACHMENT NO. 2 TO AEP:NRC:0659D DONALD C. COOK NUCLEAR PLANT UNIT NO. 2 REASONS AND 10 CFR 50.92 JUSTIFICATIONS FOR THE PROPOSED TECHNICAL SPECIFICATION CHANGES Page For clarity the Unit 2 T/S proposed changes are grouped into several categories. Many of these changes are to achieve consistency with the Unit 1 T/S and the STS. Page references to these documents are given where appropriate.

A) The purpose of the first group of proposed changes is to make the Unit 2 Action Statements 2 and 6 like the Unit 1 T/S and the STS. Specifically we would like to change the phrase "one additional" to "the inoperable."

This change is one that constitutes an additional restriction not presently included in the T/S. Therefore this change does not involve a significant hazards consideration as defined in 10 CFR 50.92.

Action Statement 2; Unit 2 3/4 3-5 Unit 1 3/4 3-6 STS 3/4 3-7 Action Statement 6; Unit 2 3/4 3-6 Unit 1 3/4 3-7 STS 3/4 3-8 B) The second group of proposed changes to Unit 2 T/S requests an extension to the period of time in which one channel of our solid state protection system can be bypassed for surveillance testing. Specifically, we are requesting the one-hour time limit be extended to two hours in Action Statement 1 and Action Statement 13. The reasons for these changes are the same as those proposed for Unit 1 Category C. Although the changes may result in some increase to the probability or consequences of a previously analyzed accident or may reduce in some way a safety margin, the results of the change are clearly within all acceptable criteria with respect to the systems specified in the STS. Therefore, we believe that these changes do not involve significant, hazards considerations as defined by 10 CFR 50.92.

Action Statement 1; Unit 2 3/4 3-5 STS 3/4 3-9 (Action Statement 12)

Action Statement 13; Unit 2 3/4 3-21 STS 3/4 3-29 (Action Statement 14)

C) The third proposed change to the Unit 2 T/S is an editorial change to Action Statement 2, part C on page 3/4 3<<5. This change adds a reference clearly defining the specification by which the quadrant power tilt ratio is to be measured. This change is purely administrative in nature and is intended to achieve consistency with the Unit 1 T/S and with the STS.

Therefore, we believe this change does not involve significant hazards consideration as defined in 10 CFR 50.92.

Page

References:

Unit 1 3/4 3-6 STS 3/4 3-7 Page D) The fourth proposed change to the Unit 2 T/S is a change to Action Statement 16 on page 3/4 3-21. This change updates the T/S regarding the conditions under which operation may proceed with the number of operable channels less than total number of channels. The proposed change will achieve consistency with the STS. Although it is a change which may result in some increase to the probability or consequence of a previously analyzed accident or may reduce in some way a safety margin, the result of the change is clearly within all acceptable criteria with respect to the systems specified in the STS. Therefore, we believe that this change does not involve significant hazard consideration as defined by 10 CFR 50.92.

4.3.1.1.2 The logic for the interlocks shall be demonstrated. OPeRABLE prior to each reactor star tup unless performed during the preceding 92 days. The total interlock function shall be demonstrated OPERABLE't least once per 18 months during CHANNEL CALIBRATION testing of each channel affected by interlock operation.
