WPPSS NUCLEAR PROJECTS 3 AND 5 508/79-10-06 AND 509/79-09-03 FAILURE OF CHICAG0 BRIDGE AND IRON TO QUALIFY WELDING PROCEDURES IN ACCORDANCE WITH SPECIFIED ASME REQUIREMENTS

References:

1) Letter, G. S. Spencer to N. O. Strand, "NRC Inspection WNP-3/5," dated December 14, 1979.

2) G03-80-91, letter, D. L. Renberger to G. S. Spencer, same subject, dated January 18, 1980.

' same subject, dated September 4, 1980.

Reference 4 details the NRC position concerning qualification require-ments for Chicago Bridge and Ircn welding procedure specification E-7018/ 74- 3431, Revision 2. This position is consistent with your original infraction notice. In response thereto, enclosed are additional CB&I procedure qualification records which include the maximum amperages specified in the WPS for 1/8 inch and 5/32 inch electrode diameters. The enclosed test data supplements the original l procedure qualification records and is believed to satisfy the require .

ments of Reference 4. It should be noted that the test results did not list the actual interpass temperature for each pass. However, CB&I has documented in the cover letter that the actual interpass temperature was just below the maximum specified interpass temperature.

As previously stated in Reference 2, WNP-3/5 does not agree' with the

. fundamental NRC position in this matter. Specifically, we are concerned with the NRC's request to invoke code requirements that are. issued after !

the effective date of a construction contract. For the case in question the effective contract date is October,1974 and the effective. ASME Code is the 1974 Edition,' including the Summer 1974 Addenda. .The procedure qualification requirements, referred to in NRC letter Reference 4, were !

added to the ASME Code in the 1977 Edition, Winter 1978 Addenda. . We. ;

find no requirement nor intent in the ASME Code to make these new i requirements retroactive nor is such 'elt to be normal industry practice; ,

other than~on an exception basis WNP-3/5 intends to follow that practice !

in the future. l Very truly yours, ;

Acting Program Director, WNP-3/5 '

SATSOP JCBS :"E UNITS #3 AND #5 m o s . saem 21~$ s . .m t Ch:1s, To confirm our phone conversation yesterday concerning che NRC's interperation of ASME Section IX, S74 Addenda, Paragraph 409.1 and the addi:ional procedure qualification run by C3I, covered by TNC Number 213-l5. The two items dicussed were an error in :ecording of amps used on PQR 4657 (co::ected copy attached) '

and how :he procedures were run wir.h respec: to interpass temperature. Each procedu:e# was qualified by adding weld layers as soon as the tes sample cool-ed to S00 , which is the maximum interpass cemperature.

Again we would state that based on previous code inquires the NRC's position is no: pa:al1el :o that o! the code. We* use as an exampie M:. Sagner's 1e::e:

to Mr. Chris:ensen, dated 8-9-77, see copy attached.

! you have any othe: questions or if we can be of any assistance please let us know.
