1.0 DESCRIPTION

This letter is a request by Indiana Michigan Power Company (I&M) to amend Facility Operating Licenses DPR-58 and DPR-74 for the Donald C. Cook Nuclear Plant (CNP) Units I and 2. The proposed change modifies Technical Specifications (TS) to reflect standard wording incorporated in NUREG-1431, Revision 3, "Standard Technical Specifications, Westinghouse Plants," (STS) for plants with installed bypass test capability. The proposed change also corrects an administrative error incorporated through implementation of an amendment approved by Reference 1. The proposed change to reflect installed bypass test capability will prevent unnecessary TS Action entry.

2.0 PROPOSED CHANGE

TS 3.3.1, RTS Instrumentation, Condition C, Required Action C.1 Note would be changed to state, "One channel may be bypassed for up-to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for surveillance testing and setpoint adjustment." TS 3.3.1, Condition D,'Required Action D. 1 Note would be changed to have two notes. A new note, Note 1, would be added that states, "For Functions with installed bypass test capability, one channel may be bypissed for up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for surveillance testing and setpoint adjustment." The current note, to be miade Note 2, would be changed to state, "For Functions with no installed bypass test capability, the inoperable channel, except Function 1 .channel, may be bypassed for up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for surveillance testing of other channels." TS 3.3.2, ESFAS Instrumentation, Condition D, Required Action D.1 Note would also be changed to have two notes. A new note, Note 1, would be added that states, "For Functions with installed bypass test capability, one channel may be bypassed for up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for surveillance testing and setpoint adjustment." The current note, to be made Note 2, would be changed to state, "For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for surveillance testing of other channels." Bypass test capability is installed or planned for installation for the following TS RTS and ESFAS Instrumentation Functions:

TS 3.3.1 Function 2 Power Range Neutron Flux Function 3 Power Range Neutron Flux - High Positive Rate Function 6 Overtemperature Differential Temperature Function 7 Overpower Differential Temperature Function 8 Pressurizer Pressure Function 9 Pressurizer Water Level - High Function 10 Reactor Coolant Flow - Low Function 14 Steam Generator Water Level -Low Low Function 15 Steam Generator Water Level coincident with Steam Flow /

Feedwater Flow Mismatch

Enclosure 2 to AEP:NRC:6331-04 Page 3 TS 3.3.2 Function L.c Safety Injection - Containment Pressure - High Function 1.d Safety Injection - Pressurizer Pressure - Low Function I.e Safety Injection - Steam Line Pressure Function 4.d Steam Line Isolation - Steam Line Pressure - Low Function 4.e Steam Line Isolation - High Steam Flow in Two Steam Lines coincident with Tavg - Low Low Function 5.b Turbine Trip and Feedwater Isolation - Steam Generator Water Level - High High Function 6.c Auxiliary Feedwater - Steam Generator Water Level - Low Low Function 7.c Containment Air Recirculation/Hydrogen Skimmer System - Containment Pressure - High TS 3.3.1, Condition Q would be changed for the condition whereby the Required Action and associated Completion Time is not met for Condition D from "for Function 2.b, 3.a, 3.b, 6..." to "for Function 2.b, 3, 6..." By Reference 2, I&M requested changes to the reactor trip on turbine trip interlock from P-7 to P-8. Reference 3 supplemented Reference 2 by providing additional TS pages which added a new Condition and changed Condition P to Condition Q. As of the date of this license amendment request (LAR), the Reference 2 LAR has not been approved.

Reference 2 requested approval of the TS changes to the reactor trip on turbine trip by October 1, 2006, in support of the Unit 1 Cycle 21 (Fall 2006) refueling outage. TS pages reflecting this proposed change are based on the TS pages provided in the Reference 2 LAR as supplemented by Reference 3.

In summary, the proposed change would modify TS to allow channels with installed bypass test capability to be bypassed while performing surveillance testing on the bypassed channel without unnecessary TS Action entry and correct an administrative error in a Condition statement.

Changes to TS Bases 3.3.1 and 3.3.2 are required to reflect changes to the Required Action Note for bypassing channels with installed bypass test capability. These changes will be made in accordance with the CNP TS Bases Control Program.

3.0 BACKGROUND

3.1 System Descriptions The CNP Updated Final Safety Analysis Report (UFSAR), Section 7.2, Protective Systems, states that the protective systems consist of both the RTS and ESFAS. The nuclear instrumentation system (NIS) and the Foxboro analog / digital protection system are part of the protection system which provide bistable output signals to the solid state protection system based on process measurement signals. Design criteria for protection systems permit maximum effective use of process measurements both for control and protection functions, thus enhancing the capability to provide an adequate system to deal with the majority of common mode failures as well as to provide redundancy for critical control functions. This diversity in the design

Enclosure 2 to AEP:NRC:6331-04 Page 4 approach provides a protection system which monitors numerous system variables by different means.

The RTS and ESFAS utilize I-out-of-2, 2-out-of-3, and 2-out-of-4 coincidence logic from redundant channels to initiate protective actions. Removal of one actuation channel for test is accomplished by either placing that channel in a tripped state, where a 2-out-of-3 logic becomes a 1-out-of-2 logic, or using bypass capability, where a 2-out-of-4 logic becomes a 2-out-of-3 logic. Within these systems, analog and digital channel comparators, with the exception of NIS I-out-of-2 functions and the ESFAS containment spray function, are placed in the tripped state in response to an inoperable channel. With an inoperable channel in the tripped state, maintenance or testing cannot be performed on a redundant channel unless one of the channels is bypassed. In addition, with a channel in the tripped condition, a second comparator trip in a redundant channel caused by human error, a spurious transient, or channel failure would initiate a reactor trip or safeguards actuation. With bypass test capability, a channel may be bypassed for surveillance testing with an inoperable channel in the tripped state.

With the implementation of test in bypass, additional time will be available to perform surveillance testing while preventing a spurious reactor trip or safeguards actuation since the partial trip conditions (e.g. one channel in a 2-out-of-4 logic placed in trip) that would have been present are eliminated. The logic requiring signals from two additional channels to actuate the protective function is maintained. This provides the benefits of reducing challenges to the plant safety systems that may result from spurious actuations and thus potentially increasing plant availability. Administrative controls will be provided to prevent the simultaneous bypassing of more than one redundant protection set at any one time, and to restore the system to normal operation.

The bypass test instrumentation modification is currently planned in two phases for installation during outages on each unit. The first phase will introduce bypass circuitry for the Foxboro analog / digital protection system reactor trip functions and engineered safety features functions and the second phase will introduce bypass circuitry for NIS functions. Procurement of an NIS Bypass panel is required to install bypass circuitry for NIS functions. Hardware modifications will be made to both the NIS and Foxboro analog / digital protection system to ensure that test in bypass may be accomplished without lifting leads or installing temporary jumpers. A bypass panel will be installed in the NIS to provide a second source of 118 VAC power in place of the output of a bistable function. The modification of the Foxboro analog / digital protection system involves installing bypass hardware to provide the bypass test capability; however, the channels will still have the capability to be put into trip, if necessary. These modifications will be made in accordance with the requirements of 10 CFR 50.59.

The status of a channel in the bypass condition will be provided both in the control room and locally. Both the NIS and Foxboro analog / digital protection system will retain the ability to test with a channel in trip. The design has also considered fault conditions, qualification, reliability

Enclosure 2 to AEP:NRC:6331-04 Page 5 and credible failures. The systems are designed such that credible failures will not result in a function being automatically placed in a bypassed condition.

3.2 Reason for Requesting Amendment Changing the Required Action Notes for applicable RTS and ESFAS instrumentation to reflect installed bypass test capability will allow surveillance testing to be performed without unnecessary TS Action entry. Changing the entry requirements for Condition Q clarifies the requirements if the Required Action and associated Completion Time of Condition D is not met for Function 3.

4.0 TECHNICAL ANALYSIS

TS Task Force (TSTF) generic change traveler TSTF-418, "Reactor Protection System and ESFAS Test Times and Completion Times (WCAP-14333)," Revision 2 established that bypass testing was an acceptable method of testing. TSTF-418 was incorporated into NUREG-1431, Revision 3 recognizing plants that have installed bypass test capability. By changing the Required Action Notes to reflect STS wording, the proposed change aligns the CNP TS with the STS, and prevents unnecessary TS Action entry.

No modifications to setpoint actuations, trip setpoints, surveillance requirements or channel response are associated with this change. Hardware changes necessary to be made to the NIS and Foxboro analog / digital protection system to facilitate testing in bypass will be implemented in accordance with 10 CFR 50.59. The hardware modifications to facilitate testing in bypass without lifting leads or the use of temporary jumpers meet the conditions specified by the U. S.

Nuclear Regulatory Commission (NRC) Staff in the Safety Evaluation Reports issued during the review of WCAP-10271, "Evaluation of Surveillance Frequencies and Out of Service Times for the Reactor Protection Instrumentation System," (Reference 4) and its supplements.

The change to Condition Q aligns the Condition entry requirements with TS 3.3.1, Table 3.3.1-1.

By the Reference 1 Safety Evaluation, NRC approved the removal of Function 3.b, Power Range Neutron Flux - High Negative Rate from TS. This amendment also approved changing Function 3.a, Power Range Neutron Flux - High Positive Rate, to Function 3. Additional technical information supporting the removal of the Power Range Neutron Flux - High Negative Rate trip function is provided in Reference 5.

to AEP:NRC:6331-04 Page 6 5.0 REGULATORY SAFETY ANALYSIS 5.1 No Significant Hazards Consideration Indiana Michigan Power Company (I&M) has evaluated whether a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed change involve a significant increase in the probability of occurrence or consequences of an accident previously evaluated?

Response: No The proposed change reflects NUREG- 1431, Revision 3, "Standard Technical Specifications, Westinghouse Plants," (STS) wording for plants with installed bypass test capability and aligns Technical Specification (TS) Condition entry requirements with other portions of the TS. The proposed changes do not modify how the reactor trip system (RTS) and engineered safety features actuation system (ESFAS) functions respond to any accident condition. The proposed changes to the TS Required Action Notes prevent unnecessary TS Action entry during performance of surveillance testing. The probability of accidents previously evaluated remains unchanged since the proposed change does not affect any accident initiators. The consequences of accidents previously evaluated are unaffected by this change because no change to any accident mitigation scenario has resulted and there are no additional challenges to fission product barrier integrity.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No No changes are being made to the plant that would introduce any new accident causal mechanisms. The proposed change to the Required Action Notes and Condition entry requirements does not adversely affect previously identified accident initiators and does not create any new accident initiators. The change does not affect how the RTS and ESFAS functions operate. No new single failures or accident scenarios are created by the proposed change and the proposed change does not result in any event previously deemed incredible being made credible.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

Enclosure 2 to AEP:NRC:6331-04 Page 7

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No No safety analyses were changed or modified as a result of the proposed TS change to reflect STS wording for plants with installed bypass test capability or for aligning TS Condition entry requirements. All margins associated with the current safety analyses acceptance criteria are unaffected. The current safety analyses remain bounding. The safety systems credited in the safety analyses will continue to be available to perform their mitigation functions. The proposed change does not affect the availability or operability of safety-related systems and components.

Therefore, the proposed change does not involve a significant reduction in the margin of safety.

Based on the above, I&M concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.

5.2 Applicable Re2ulatory Reg uirements/Criteria 10 CFR 50.36 requires that each license authorizing operation of a production or utilization facility include TS. The TS are required to include Surveillance Requirements (SRs), which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that the facility operation will be within safety limits, and that the limiting conditions for operation will be met. This amendment changes TS Required Action Notes to allow certain RTS and ESFAS Instrumentation SR to be performed without TS Action entry.

In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the NRC's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health or safety of the public.

6.0 ENVIRONMENTAL CONSIDERATION

S A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

to AEP:NRC:6331-04 Page 8 Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
