Mail Stop P-1132 U.S. Nuclear Regulatory Commission Washington, DC 20555

Dear Dr. Liaw:

This letter is being sent to document the visit of Messrs. P. Hasters, W.H. Munse, R.D. Stout and myself to the Sequoyah Nuclear Units on February 26-28, 1986. This site visit was made in conjunction with our duties as Expert Welding Team members on FIN A-3839 entitled " Evaluation of Welding Concerns at TVA Operating Reactors."

The trip report is broken up into three parts; each part will cover one days activity of the visit.

February 26, 1986 A. meeting was held at the Sheraton East Ridge, Chatanooga TN, at 15:00 hours on February 26, 1986. The meeting was attended by both USNRC personnel and welding consultants (Attachment #1). The purpose of the meeting was to discuss the TVA Welding Concern Program and establish the Celding Team Charter. Informal presentations were made by the following:

D. Smith /U. Long

1. Discussed an overview of the TVA welding concern program and established the charter of the Expert Welding Team.

2. The charter of the Team is not to address any vendor welds- 't will only address site related problems.

3. There are approximately 60 Sequoyah concerns on welding .out 500 total welding concerns.

4. Definitions of various acronyms were discussed, e.g., NSRS, QCT, LER, etc.

Czajkowski to Liaw March 18, 1986 A. Herdt

1. Provided a discussion of TVA history of the plants including:

a. potential " generic" concerns

b. the fact that TVA does its own construction and design on its units

c. a definition of " employee concern"

2. Discussed the public meeting between USNRC and TVA of January 7,1986.

3. Described the TVA and USNRC telecon discussions of January 9,1986, and TVA's commitment for a physical reinspection of their plants.

4. Detailed the January 29, 1986, inspection report of Messrs. Crowley, Smith and Cortland.

a. Discussed report's Executive Summary

5. Described the work the USNRC NDE Van was performing at Sequoyah Units 1 and 2.

C. Czajkowski .

After NRC personnel left the meeting, I addressed the Team and detailed the specifics of the contract, the type of reports required, and most importantly, the independence which must, be maintained by the Team of Experts.

February 27, 1986 A meeting was held at 10:00 hours at the Sequoyah Nuclear Plant site between TVA personnel, USNRC personnel and the Welding Team (Attachment

1. 2). A presentation was made by TVA personnel (Attachments 3-6) of the planned activities of TVA in evaluating the employee concerns expressed about the Sequoyah site.

Af ter the presentation, the Welding Team and NRC personnel were escorted on a tour of both *outts 1 and 2 (and common aress to both) which included many of the welds which were inspected by either TVA or the USNRC NDE Van or both.

Various stru r.aral welds and pipe welds were visually examined by the Team with no abnormalities noted.

Af ter the tour, the Welding Team discussed their observstions with USNRC NDE Van personnel.

' Czajkow. ski to Linw February 28, 1986 The Exit Critique of findings by NRC NDE Van personnel was convened at 10:41 hours (Attachment 7). The report of findings were given the number 327/328 86-13. The Van personnel had reviewed documentation for fifty pipe welds as well as seventeen structural weld packages. NRC Van personnel had inspected approximately:

350 structural welds (already inspected by TVA) 190 new structural welds (not previously inspected) 35 pipe welds (already inspected by TVA) 12 new pipe welds (not previously inspected)

There were some follow up NRC items from the inspection and some areas which were still under evaluation by NRC personnel, but one point was made on the reinspection:

"Me differences observed on the quality of welds inspected 2re not considered unusual or worse than industry norms.

I would like to note that both the TVA and NRC personnel were most forthright in providing answers to the Team in a timely and professional manner. If there are any questions, please contact me.

Veq truly yours, I j '
