Dear Sir or Madam:

Per Reference 1, Luminant Generation Company LLC (Luminant Power) submitted proposed changes to the Comanche Peak Steam Electric Station, herein referred to as Comanche Peak Nuclear Power Plant (CPNPP), Unit 1 and Unit 2 Technical Specifications to allow the use of several Nuclear Regulatory '

Commission (NRC) approved accident analysis methodologies to be used to establish core operating limits. Included in that submittal were different methods for analyzing the small break loss of coolant accident (LOCA) and the large break LOCA. As prescribed in the NRC's Safety Evaluations approving the generic use of these methods, and in compliance with 10CFR50.46, Luminant Power transmitted, per Reference 2, the evaluation models and results developed in accordance with those methodologies for NRC review.

U. S. Nuclear Regulatory Commission TXX-08051 Page 2 03/13/2008 On November 2, 2007, the NRC provided Luminant Power with a request for additional information regarding the large and small break loss-of-coolant accidents for Comanche Peak. The response to these questions was provided in Reference 3 and 4.

As stated in Reference 1, Lumnant Power will continue to use the currently approved methodologies to support the remaining Unit 1, Cycle 13 operation and complete the transition to the proposed methodologies prior to Unit 1, Cycle 14 operation (Fall 2008). However, Luminant Power did not include the currently applicable Technical Specifications for Constant Axial Offset Control (Heat Flux Hot Channel Factor and Axial Flux Difference) for the remainder of Unit 1, Cycle 13 operation with the marked up Technical Specifications in Reference 1; only the final markup was provided after both Comanche Peak Units 1 and 2 have completed transitioning to the proposed methodologies. provides markups to the Technical Specifications, including the current applicable Technical Specifications as described in Reference 1 to differentiate between the implementation of the Technical Specification changes in Unit 2 (Spring 2008) and Unit 1 (Fall 2008). Attachment 2 provides clean retyped pages for the Technical Specifications, including the current applicable Technical Specifications as described in Reference 1.

In accordance with 10CFR50.91(b), Luminant Power is providingthe State of Texas with a copy of this proposed amendment.

This communication contains no new licensing basis commitments regarding Comanche Peak Units 1 and 2.

Should you have any questions, please contact Mr. J. D. Seawright at (254) 897-0140.

I state under penalty of perjury that the foregoing is true and correct.

Executed on March 13, 2008.
