Licensee Action on Previous Inspection Findings (Closed) Inspector Follow Item (354/83-15-01):
Verification that vessel mechanized ultrasonic tracks are properly installed.
Subsequent to com-pletion of the ultrasonic examination of reactor pressure vessel welds, the inspector reviewed selected data associated with the weld examinations which required the use of the tracks in question.
The data indicated that the applicable ASME Code requirements were met regarding the required weld examination volume and, therefore, the tracks, as installed, were properly located.
-Based on the above, this item is considered closed.
(Closed) Unresolved Item (354/84-15-02): PSI requirements regarding welds in close proximity. The unresolved item questioned whether the PSI requirements could be met for 14" diameter elbow to pipe weld number 5 and 14" diameter pipe to elbow weld number 6 on line number 1-BJ-14DBB-003B due to their close proximity to each other.
These are ASME Class 2 welds which require a surface examination and a volumetric examination.

A review of licensee records indicated that volumetric examination and surface examination requirements were met.
The volumetric (ultrasonic)
examination was performed from the elbow side of each weld and the surface (magnetic. particle) examination was performed with a magnetic yoke using the dry powder, continuous method.
The data sheets identified the welds as number 4 and number 5.
The apparent discrepancy was questioned by the inspector. He verified that weld numbers were changed on isometric drawing numbers 1-P-BJ-001 & -002 which resulted in the weld which was originally called weld number 5 now being identified as weld number 4 and the original weld number 6 being identified as weld number 5.
Based on the above, this item is considered closed.
(Closed) Unresolved Item (354/85-08-01):
Incomplete documentation on radiographic inspection report. The Dravo radiographic inspection report dated 1/4/78 of weld number 1-BC-072-505-233-D failed to address the reason why two of the original films were unacceptable and had to be redone. The licensee has written a memo to file to identify discrepancies within the record and to clarify the record regarding the two additional radiographs.
The inspector stated that he had no further questions regarding this item and that the item is considered closed.
(Closed) Unresolved Item (354/85-08-02): The use of Customer Notification Form (CNF) by Southwest Research Institute.
The NRC questioned why no CNF was issued regarding the limitation to the ultrasonic examination of weld
,
1-AE-24DLA-036-6 as documented on Examination Record Sheet number 890027.
i-Licensee Surveillance Report number 85-26 dated 5/11/85 documents the licensee's follow-up of the item. The licensee reviewed approximately 2200 examination records for completed welds and found 70 records which do6umented limitations to the examination.
Four of those, includtr.3 weld 1-AE-24DLA-036-6, were found to have no CNF issued.
Further investigation by the licensee and SwRI indicated that weld 1-AE-24DLA-036-6 was comp-letely examined, and that no limitation to the examination should have been reported.
The inspector found that the four instances where a required CNF was not issited appeared to be isolated cases which happened between September 22, 1983 and October 4, 1983 and which involved feedwater system welds number 1-AE-24DLA-035-3 and -4, and 1-AE-24DLA-036-6. Of these four, further investigation by SwRI and the licensee revealed that two of the conditions originally reported as limitations were not limitations to the examination. The licensee stated that where legitimate limitations do exist, the final report would provide the required details.
The inspector had no further questions regarding the matter at this time and the item is considered closed.
(Closed) Unresolved Item (354/85-22-01):
Scribe lines on jet pump sensing line. The inspector reviewed the General Electric Company FDDR No.
KT1-423, Revision 0, which described and evaluated the reported condition
_
.
.
.
regarding the presenceJof scribe lines on jet pump sensing line numb'er 246. Additionally, the inspector reviewed an engineering disposition which provided justification for the disposition of the FDDR.
Based on the above, this item is considered closed.
3.
Visual Weld Acceptance Criteria By letter to NRR dated July 31, 1985, the licensee requested permission to adopt the provisions of Visual Weld Acceptance Criteria for Structural Welding at Nuclear Power Plants (VWAC). Revision 2.
This document was prepared by the Nuclear Construction Issues Group (NCIG) and is considered by the NRC to be a technically acceptable approach for visual inspection of structural weldments (and other non-ASME class structures) of nuclear power plants under the purview of American Welding Society Standard D1.1.
The licensee prepared a training program for the Quality Control inspec-tors, and was in the process of conducting training sessions for those QC inspectors during the course of this inspection. Additionally, inspection criteria ~were provided to the QC inspectors in the form of Aopendix D to Specification 10855-C-130(Q), Revision 11.
The inspector attended a training session for QC inspectors during which the new criteria were explained, and limitations to use of the criteria were discussed. Additionally, he reviewed Appendix D to the C-130 speci-fication to ascertain compliance with the new criteria.
The inspector found that the licensee's training program followed the NCIG Training Manual for Inspectors of Structural Welds at Nuclear Power Plants Using the Acceptance Criteria of NCIG-01, and that Appendix D to the C-130 specification included the.information necessary for the performance of a meaningful vi ual inspection of applicable welds.
No violations were identified.

Review of PSI Implementing Procedures The following nondestructive examination NDE procedures were reviewed by the inspector with regard to ASME Code and regulatory requirements:
SwRI-NDT-200-1, Revision 55, " Liquid Penetrant Examination, Color
Contrast Method" SwRI-NDT-300-1, Revision 23, " Dry Powder Magnetic Particle
Examination" SwRI-NDT-300-2, Revision 30, " Fluorescent Magnetic Particle
Examination" s

Pressure Vessel Welds"

SwRI-NDT-600-30, Revision 14, " Manual Ultrasonic Examination of
' Pressure-Retaining Welds in Heat Exchangers" Southwest Research Institute procedure 300-2, Revision 30, limits to the outside surface only the magnetic particle examination of reactor pressure vessel closure head nuts.. ASME Section XI does not specifically exclude from examination any available surface of the closure head nuts.
The inspector reviewed licensee records of the closure head nuts to ascertain-that ASME Code preservice inspection requirements were met.
Fabrication inspection records verified that a surface examination of all-surfaces of the nuts Lwas performed by the part fabricator. The inspector
-
found that this examination fulfills the ASME Section XI PSI requirements.
The. inspector visually examined the closure head nuts to verify that they were the items which were represented by the fabricator's inspection-reports.
He bed no further, questions regarding the matter at this time.
The remaining procedures were found to comply with ASME Code and regula-tory requirements.
No violations were identified.

Preservice~ Inspection (PSI) Data Review The inspector reviewed data associated with the following welds to ascertain that findings were properly recorded 'and evaluated, and tha,t ASME Code regulatory and procedural requirements were met:

.
The-inspector's review included examination record sheets, calibration record sheets, indication resolution record sheets and plots of ultrasonic indications.
The inspector _found that Code,-regulatory and procedural requirements were met with one exception. Ultrasonic examination records of weld 1-BJ-10DBB-003A-2 documented an indication equal to 80% of DAC which was detected during the 45 shear. wave examination. A note on the examination record sheet stated that the indication was investigated. The governing ultrasonic examination procedure 600-41, Revision 8, required that reflec-
. tors which produce a response greater than 50% of DAC must be evaluated
+
by a Level II or Level III individual.to determine the shape, identity and location of the reflector. Aside from the note on the record sheet, no further evidence of the evaluation or disposition of the indication was available at the time of this inspection.
This is considered unre-solved pending the availability of documentation regarding evaluation and disposi+' a of the indication and NRC review of the documentation (354/85-46-No violations were identified.
