Dear Sir or Madam:

Per Reference 1, Luminant Generation Company LLC (Luminant Power) requested an amendment to the Comanche Peak Steam Electric Station, herein referred to as Comanche Peak Nuclear Power Plant (CPNPP), Unit 1 Operating License (NPF-87) and Unit 2 Operating License (NPF-89) by revising the CPNPP Unit 1 and 2 Technical Specifications (TSs).

The proposed change revises TS 5.5.9.2, Unit 1 Model D76 and Unit 2 Model D5 Steam Generator (SG)

Program, to exclude portions of the Unit 2 Model D5 steam generator tube below the top of the SG tubesheet from periodic steam generator tube inspections.

The NRC provided Luminant Power with requests for additional information (RAI) via References 2 and

3. References 4 and 5 provided the responses to the RAIs. Reference 6 provided a revision to Reference 1 to be a one-time change to TS 5.5.9.2 and TS 5.6.9 for Unit 2 during Refueling Outage 11 and the subsequent inspection cycle.

U. S. Nuclear Regulatory Commission TXX-09117 Page 2 09/17/2009 On September 15, 2009, in an email between NRC Staff and Luminant Power, NRC Staff indicated the commitment for the condition monitoring assessment needed to be revised.

This communication contains the following revised licensing basis commitment which will be completed or incorporated into the Comanche Peak licensing basis as noted:

Number Commitment Due Date/Event 3779679 For the condition monitoring (CM) assessment, the During each inspection of the component of operational leakage from the prior cycle Unit 2 steam generators required from below the H* distance will be multiplied by a by TS 5.5.9.2 starting in Refueling factor of 3.16 and added to the total accident leakage Outage 2RF12.

from any other source and compared to the allowable accident induced leakage limit. For the operational assessment (OA), the difference in the leakage between the allowed accident induced leakage and the accident induced leakage from sources other than the tubesheet expansion region will be divided by 3.16 and compared to the observed operational leakage. An administrative limit will be established to not exceed the calculated value.

Luminant Power requests approval of the proposed license amendment by September 30, 2009, to support the Comanche Peak Unit 2 Fall 2009 (2RF11) refueling outage. The proposed license amendment will be implemented within 30 days of the issuance of the license amendment.

In accordance with 10 CFR 50.91(b), Luminant Power is providing the State of Texas with a copy of the proposed license amendment.

Should you have any questions, please contact Mr. Jack Hicks at (254)897-6725.
