B.
Action on Previous Inspection Findings 1.
(Closed) Deviation (Item A, Notice of Deviation, Inspection Report No. 79-01):
Procedure No. E91-014(E), Revision 4, did not assure proper adjustment or maintenance of accuracy of welding machines, in that necessary accuracy limits were not defined by the procedure.
The inspector verified that the committed revisions to Procedure No. E91-014(E), Revisio: 4, had been accomplished and the procedure re-issued as No. Mll-75314.
Issue of instructions to affected organizations, relative to inclusion of accuracy limits in proce-dures, was verified as having been performed on February 28, 1979.
The inspector additionally established that a calibration program was in effect, relative to verification of accuracy of meters on welding equipment, utilizing Calibration Procedure No. ZT-84801A.
4 2.
(Closed) Deviation (Item B, Notice of Deviation, Inspection Report No. 79-01):
Allowance by certain welding procedure specifications, which had been approved for use in applications with stipulated notch toughness properties, to use voltage values in excess of those used in performance of the supporting procedure qualifications.
The inspector verified that welding procedure specifications (WPS) 2424, Revision 2, and 2422, Revision 1, had been revised to limit the allowable voltage range up to those values used for the proce-dure qualification tests.
The inspector also confirmed that a comprehensive check list system had been established, which had been utilized to review all applicable WPS relative to their proce-dure qualification records.
C.
Integrated Quality Record Review 1.
Objective The objective of this area of the inspection was to ascertain by integrated review of procurement, vendor and IHI manufacturing records, whether QA Program controls were functioning.
2.
Method of Accomplishment The preceding objective was accomplished by review of the following records, concerning Penetration Assembly No. 401-B42 (WPPSS Project No. 3), relative to QA Program requirements:
Review of purchase orders and specifications applicable to a.
i procurement of SA 106 Grade B piping; SA 240 Type 316 sheet for bellows fabrication; SA 516 Grade 70 neck ring material; SA 376 Type 304 leak nozzle material; SFA 5.1 E7016 electrodes used for performing neck ring to pipe welds; SFA 5.9 Type ER 308L wire used for performing the leak test nozzle weld and SFAS.9 ER 316L wire used for performing bellows welds.
I b.
Examination of vendor approval status at time of procurement.
Review of vendor survey records for those vendors not holding c.
an appropriate ASME Certificate.
i' d.
Examination of Certified Material Test Reports for the referenced materials with respect to:
(1) Evidence of IHI review and approval.
(2) Compliance with procurement requirements.
(3) Material identification agreement with observed identity.
5 Examination of IHI fabrication plan for penetration assembly e.
manufacture with respect to:
(1) Definition and control of sequencing of manufacturing operations to provide for compliance with ASME Code Section III fabrication requirements.
(2) Performance of required ASME Code nondestructive examina-tions and at appropriate times of examinations.
(3) Compatibility of manufacturing operations with existing welding procedure qualifications.
f.
Examination of welding procedure specifications (WPS), which had been assigned for use in bellows cylinder welding (prior to forming), leak test nozzle welding, bellows to pipe and neck ring to pipe welding; relative to correctness of essential variable definition with respect to actual manufacturing use.
g.
Review of production welding records for the above welds relative to verification of compliance with WPS essential and nonessential variables.
h.
Examination of performance qualification records for those welders identified as performing the production welds, with respect to adequacy of qualification for the specific assigned tasks.
i.
Review of bellows vendor survey records and vendor supplied dimensional and heat treatment data.
j.
Examination of liquid penetrant examination records with respect to compliance with designated procedure and use of appropriately qualified personnel.
k.
Verification of qualification of procedure for record observed application at temperatures below 60 F.
3.
Findings a.
Deviation from Commitment See Notice of Deviation.
b.
Unresolved Items None.
6 c.
Items Requiring Further Review The inspector observed one anomaly relative to the qualification of SFA 5.1 E 7016 coated electrodes. The purchase specification for the electrodes required the manufacturer to use alternating current for performance of qualification testing. Use of these electrodes at IHI, however, involved only welding with direct current reverse polarity. Review, in the time available, of the SFA specification and ASME Section III welding material qualification requirements, failed to reveal that this practice was prohibited.
D.
Review of Browns Ferry Units 2 and 3 Reactor Vessel Welding Material Records in respect to IE Bulletin 78-12 1.
Objectives The objectives of this area of the inspection were to identify, in accordance with the requirements of IE Bulletin 78-12, the following information relative to the fabrication of Browns Ferry Unit 2 and 3 reactor vessels:
a.
Weldments performed by IHI in the two (2) reactor vessels.
b.
The type and form of welding materials and the identifying heat and lot numbers used in each weldment.
c.
The welding material manufacturers and the types and form of materials supplied.
d.
The specified analysis and mechanical properties of the welding materials and measures established to verify conformance of welding materials with specified requirements.
2.
Method of Accomplishment The preceding objectives were accomplished by:
a.
Review of IHI Document No. QAG-9Z-040, dated February 28, 1979, " List of Welding Material (Babcock & Wilcox Contract No. 610-0127 and 610-0145)."
b.
Review of IHI Specification No. QT 302-01 Revision 0, dated October 6, 1969, " Welding Material Specification for hn-Mo, Mn-Mo-Ni and Mo-Cr-Ni Steel Plate for Pressure Vessel."
c.
Review of IHI Specification No. 152E02311 Revision 1, dated October 5,1969, " Welding Material Specification for Submerged Arc Welding of Mn-Mo, Mn-Mo-Ni and Mo-Cr-Ni Steel."
7 d.

Examination and compilation of vendor Certified Material Test e.
Report data for welding materials referenced by IHI Document No. QAG-9Z-040 as being used in fabrication of the two (2)
Browns Ferry reactor vessels.
3.
Findinas Within this area of the inspection, no deviations or unresolved a.
items were identified.
b.
On review of welding material Certified Material Test Reports in the U.S. subsequent to the inspection, three (3) reports, i.e., IHI Record Nos. 67-01, 71-10 and 71-24, could not be located. Review of the test data for these coated electrodes will be made during a future inspection.
c.
(1) Table 1 shows a comp?lation of the identity and location of use of welding materials for weld joints performed by IHI in the Browns Ferry Unit 2 (Babcock & Wilcox Contract No. 610-0127) reactor vessel.
(2) Table 2 shows a compilation of the identity and location of use of welding materials for weld joints performed by IHI in the Browns Ferry Unit 3 (Babcock & Wilcox Contract No. 610-0145) reactor vessel.
(3) Table 3 shows a compilation of the chemical composition and mechanical properties of weld metals deposited by IHI in fabrication of the Units 2 and 3 reactor vessels.
d.
Examination of the data referenced in c. above shows no evidence of atypical welding materials being used by IHI in the fabrication of the Browns Ferry reactor vessels.
All testing was performed by the welding material vendors with e.
IHI surveillance of test plate welding and mechanical tests.
f.
No records were located that would indicate any additional in process testing of welding materials had been performed during fabrication of the vessels.
E.
Exit Meeting A post inspection meeting was held on September 5,1979, with the management representatives denoted in paragraph A. above. The inspector summarized
8 the scope and findings of the inspection.
