Walnut Creek, CA 94596

Dear Sir:

Attached is PGE's response to IE Bulletin 80-08 which was forwarded by your letter dated April 7, 1980. That bulletin requested information about the specifications for and examinations of Containment piping penetration welds. As the attached response indicates, the Containment penetration flued head to outer sleeve welds at Trojan were all subjected to 100 percent radiographic examination, and thus we do not consider the problem described in the bulletin to exist at Trojan.

Some of the infor-mation requested by the bulletin must be obtained from construction records, some of which have not yet been retrieved from our files.

That information should be available, if needed, by August 1, 1980.

If you have any questions regarding this response or if the unavailable information is needed to complete your review, please call me.

Sincerely, C. Goodwin, Jr.

Response to IE Bulletin 80-08 Examination of Containment Liner Penetration Welds i

Item'1 Determine if your' facility contains the flued head design fo~r penetration connections, or other designs with Containment boundary butt weld (s)~

between the penetration sleeve and' process piping as illustrated in Figure NE 1120-1, Winter 1975 Addenda to the 1974 and later editions of the ASME B&PV Code.

Response

Containment piping penetrations at Trojan are of the flued head design with Containment' boundary butt welds as described above.

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

(a) Applicability of the ASME Code including year and addenda and/or Regulatory Guide 1.19, (b) Type of nondestructive. examinations performed during construction, (c) Type of weld joint (including pipe material and size) and s

whether or not backing bars were used, (d) Results of construction nondestructive examinations, i.e.,

if repairs were required, this should be identified including extent of repairs and description of defects encountered during repair, if known.

'Responce:

The applicable code for the Containment piping penetrations is ASME B&PV L

Code _Section III,-1971 Edition with Addenda through Winter 1971.

Penetra-tions are also.in accordance with Regulatory Guide 1.19.

Nondestructive examinations performed during. construction consisted of 100 percent radiography.

Full penetration butt welds were used.

The attached Table I provides identification of Containment piping penetrations and the line size, piping material, if backing. rings were used and type of defect for any repair work for each penetration.
