SUBJECT: COMANCHE PEAK STEAM ELECTRIC STATION - SPECIAL TEAM INSPECTION

REPORT 50-445/02-09 - FINAL SIGNIFICANCE DETERMINATION FOR A

WHITE FINDING AND NOTICE OF VIOLATION

Dear Mr. Blevins:

The purpose of this letter is to provide you the final results of our significance determination of

the preliminary White finding identified in the subject inspection report. The inspection finding

was assessed using the Significance Determination Process and was preliminarily

characterized as White (i.e., a finding with low to moderate increased importance to safety,

which may require additional NRC inspections). This White finding involved the failure to

identify and correct an indicated flaw in a steam generator tube during Refueling

Outage 1RF08. Failure to remove the tube from service resulted in a steam generator tube

leak, which occurred in the 2002 time frame.

In a telephone conversation with Mr. Claude Johnson of the Nuclear Regulatory Commission

(NRC), Region IV, on February 5, 2004, Mr. Fred W. Madden, Nuclear Licensing Manager, of

your staff indicated that TXU Energy does not contest the characterization of the risk

significance of this finding and that you have declined to discuss this issue in a Regulatory

Conference or provide a written response.

After considering the information developed during the inspection, and the additional

information you provided in your letters dated March 5 and April 9, 2003, the NRC has

concluded that the inspection finding is appropriately characterized as White, because the tube

failed in-situ testing. This failure indicated a higher probability of inservice failure for the tube

during postulated initiating events and core damage sequences.

You have 30 calendar days from the date of this letter to appeal the staffs determination of

significance for the identified White finding. Such appeals will be considered to have merit only

if they meet the criteria given in NRC Inspection Manual Chapter 0609, Attachment 2.

The NRC has also determined that the failure to identify and correct a clearly detectable steam

generator tube flaw indication, during eddy current examinations in the 2001 refueling outage

(1RF08) resulting in the tube remaining in service until it leaked in September 2002, is a

violation of 10 CFR Part 50, Appendix B, Criterion XVI, as cited in the attached Notice of

Violation (Notice). The circumstances surrounding the violation are described in detail in the

subject inspection report. In accordance with the NRC Enforcement Policy, NUREG-1600, the

Notice of Violation is considered escalated enforcement action because it is associated with a

White finding.

You are required to respond to this letter and should follow the instructions specified in the

enclosed Notice when preparing your response.

Because plant performance for this issue has been determined to be in the regulatory response

band, we will use the NRC Action Matrix to determine the most appropriate NRC response for

this event. We will notify you, by separate correspondence, of that determination.

In accordance with 10 CFR 2.790 of the NRCs Rules of Practice, a copy of this letter and its

enclosures will be available electronically for public inspection in the NRC Public Document

Room or from the Publicly Available Records (PARS) component of NRCs document system

(ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-

NOTICE OF VIOLATION

TXU Energy

Docket No. 50-445

Comanche Peak Steam Electric Station

License No. NPF-87

EA-04-009

During an NRC inspection conducted from October 7 through November 1, 2002, a violation of

NRC requirements was identified. In accordance with the "General Statement of Policy and

Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:

10 CFR Part 50, Appendix B, Criterion XVI requires, in part, that licensees shall

establish measures to assure that conditions adverse to quality are promptly identified

and corrected.

Contrary to the above, in April 2001, despite the existence of eddy current data that

indicated the existence of a flaw in a steam generator tube, the licensee failed to

promptly identify a flaw in Comanche Peak, Unit 1, Steam Generator No. 2 Tube

R41C71, a condition adverse to quality, and correct it by removing it from service. As a

result, in September 2002, the flaw developed into a leak that caused operators to shut

the plant down. The tube subsequently failed in situ testing.

This violation is associated with a White Significance Determination Process finding.

Pursuant to the provisions of 10 CFR 2.201, TXU Energy is hereby required to submit a written

statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document

Control Desk, Washington, DC 20555 with a copy to the Regional Administrator, Region IV, and

a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, within

30 days of the date of the letter transmitting this Notice of Violation. This reply should be

clearly marked as a "Reply to a Notice of Violation; EA-04-009" and should include for each

violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation or

severity level, (2) the corrective steps that have been taken and the results achieved, (3) the

corrective steps that will be taken to avoid further violations, and (4) the date when full

compliance will be achieved. Your response may reference or include previous docketed

correspondence, if the correspondence adequately addresses the required response. If an

adequate reply is not received within the time specified in this Notice, an order or a Demand for

Information may be issued as to why the license should not be modified, suspended, or

revoked, or why such other action as may be proper should not be taken. Where good cause is

shown, consideration will be given to extending the response time.

If you contest this enforcement action, you should also provide a copy of your response, with

the basis for your denial, to the Director, Office of Enforcement, United States Nuclear

Regulatory Commission, Washington, DC 20555-0001.

Because your response will be made available electronically for public inspection in the NRC

Public Document Room or from the NRCs document system (ADAMS), accessible from the

NRC Web site at http://www.nrc.gov/reading-rm/adams.html, to the extent possible, it should

not include any personal privacy, proprietary, or safeguards information so that it can be made

available to the public without redaction. If personal privacy or proprietary information is

-2-

necessary to provide an acceptable response, then please provide a bracketed copy of your

response that identifies the information that should be protected and a redacted copy of your

response that deletes such information. If you request withholding of such material, you must

specifically identify the portions of your response that you seek to have withheld and provide in

detail the bases for your claim of withholding (e.g., explain why the disclosure of information will

create an unwarranted invasion of personal privacy or provide the information required by

10 CFR 2.790(b) to support a request for withholding confidential commercial or financial

information). If safeguards information is necessary to provide an acceptable response, please

provide the level of protection described in 10 CFR 73.21.

Dated this 13th day of February 2004
