June 27, 1980 1-060-23 2-060-32 Mr. K. V. Seyfrit, Director Office of Inspection & Enforcement U.S. Nuclear Regulatory Commission Region IV 611 Ryan Plaza Drive, Suite 1000 Arlington, Texas 76011

Subject:

Arkansas Nuclear One - Units 1 and 2 Docket Nos. 50-313 and 50-368 License Nos. DPR-51 and NPF-6 IE Bulletin 80 Examination of Containment Liner Penetration Welds (File: 1510.1 and 2-1510.1)

Gentlemen:

Following is our response to specific items of IE Bulletin 80-08.

Item 1: " Determine if your facility contains the flued head design for penetration connections, or other designs with containment boundary butt weld (s) between the penetration rie--e and pro-cess piping as illustrated in Figure NE 1120-0. nter 1975 Addenda to the 1974, and later editions of the $SME B&PV Code."

Reply: Both ANO Unit 1 and Unit 2 utilize the flued head design for containment penetrations. All such penetrations are listed in Attachments I and II.

Item 2: If an affirmative answer is reached for Item 1, determine the following:

a. Applicability of the ASME Code, including year and ad-denda and/or Regulatory Guide 1.19.

b. Type of noudestructive examinations performed during construction.

)

i .

c. Type of weld joint (including pipe material and size) and whether or not backing bars were used.

d. Results of construction nondestructive examinations, i.e., if repairs were required. This should be iden-tified including extent of repairs and description of defects encountered during repair, if known.

Reply: a. The applicable codes indicated on Attachments I and II.

b. All flued head penetrations at ANO Unit I and Unit 2 were radiographed.

c. All welds are butt welds, without backing bars. Material and size information is contained in Attachments I and II.

d. See Attaenment III and IV.

Item 3: "For those facilities committed during construction to perform volumetric examinations of such penetrations through SAR commitments which have not performed radiography, justify not performing radiography or submit plans and schedules for performing radiographic examinations."

Reply: As stated in response to Item 2b, all such welds at ANO were radiographed. Therefore, this item is not applicable.

^

As noted in our letter from Mr. J. P. O'Hanlon to Mr. G. L. Madsen, dated May 27, 1980, our investigations revealed one flued head pene-tration weld which had not been repaired to correct a lack of fusion defect identified during construction. This defect has been repaired.

Very truly yours,
