Date' ComponentsSection I Vendor Inspection Branch Summary Inspection on September 9-12, 1980 (99900002/80-02)
Aress Inspected:
Implementation of 10 CFR 50, Appendix B, including centrol of special processes; material controls; handling, storage and shipping; and action on previous findings. The inspection involved twenty-six (26) inspector hours on site by one NRC inspector.
Results:
In the four (4) areas inspected no apparent deviations or unresoived items were identified in three (3) areas. The following deviation was identified.
Deviation: Control of Special Processes - Some tack welding of Grid Cage Assemblies was not fully controlled in that (1) welding was beyond the voltage range specified, (2) amperage range was not documented of the quali-fication, (3) noncalibrated equipment was used and (4) electrical variables were changed without requalification as required by the QA Manual Section 10.

B.
Action on Previous Inspection Findings 1.
(Closed) Deviation (Report No. 80-01):
One lot of nonconforming fuel rods was not properly identified and one Deviation Notice was changed improperly. A review of nonconforming materials and their associated Deviation Notices found no additional problems in these areas.
2.
(Closed) Unresolved Item (Report No. 30-01):
C.E. agreed to find the Upper End Fitting Posts crimp qualification.
The qualification report was found and reviewed by the inspector.
C.
Control of Special Processes 1.
Objectives The objectives of this area of the inspection were to verify that special processes are properly qualified and controlled in accordance with Criterion IX, Appendix 3, 10 CFR 50 and the Quality Assurance Manual.
2.
Method of Accomplishment The preceding objectives were accomplished by:
Review of the Quality Assurance Manual, dated March 1, 1977, a.
Section 10, Control of Special Processes, which established u_
general requirements for control of special processes.
b.
Review of Standard Engineering Specification for 14 X 14 Fuel Assemblies 00000-FCD-0100, Revision 0, and drawing Fuel Bundle Assembly Batch F, E 3167-701-301, Revision 1, which established the design requirements.
3 Review and inspection of the following procedures:
c.
Procedures / Drawings Listing for Fuel Assemblies, Mfg-14-11, Revision 23.
Process Specification for Weld Repairing, Mfg-08-32, Revision 4, Procedure for Performance Welding Qualification, Mfg-08-13, Revision 1, Fitting / Grid Cage Assembly and Tack Weld Lock Disc, O.S.1140, Revision 3, Weld Grids to Grid Tubes, O.S. 187, Revision 4, and Welding Pro' cess Data Sheets P-598, Revision 3, and P-576, Revision 3 which established specific requirements.
d.
Observation and inspection of tack welding of Lock Discs and Spacers, inspection of the welder qualification records, Qualification Data Sheets, Welding Performance Qualification Log, Record of Weld Performance Qualification, and review of the weld gas certifications.
3.
Findings a.
Deviation See Notice of Deviation enclosure.
b.
Unresolved Item None.
c.
Comment It is C.E.'s position that the electrical variables in manual tungsten are welding are nonessential variables.
It is C.E.'s feeling that as nonessential variables then requalification, use of calibrated equipment, etc. is not necessary.
The current pro-cedure Mfg-08-13 does not distinguish between what are essential and nonessential variables. Paragraph 7.4.3 calls for requali-fication if a change in the welding variables shown on the Qualification Data Sheet.
C.E. preventati re action will be to revise procedure Mfg-08-13 to add distinction.
4 D.
Material Controls 1.
Objectives The objectives of this area of the inspection were to verify that:
a.
The system for identification and control of materials, parts, components and subassemblies during fabrication is sufficient to prevent the use of incorrect or defective materials, parts or components.
b.
A system is utilized which will insure that all manu-facturing and inspections steps are accomplished in the prescribed sequence.
2.
Method of Accomplishment The preceding objectives were accomplished by:
Review of the ASME Section III, Division I, Class I, Quality a.
Assurance Manual, dated February, 1978, Section 4, Process Control, which established the general requirements for saterials controls.
b.
Inspection of twelve (12) lots of raw materials and finished material in storage and six (6) lots of materials in process on the shop floor. This inspection verified implementation of the above requirements in the East Windsor Plant.
c.
Verification that the materials identified above were traceable to material test reports and the status of the material was identified.
3.
Findings a.
Deviations None.
b.
Unresolved Items None.
E.
Handling, Storage and Shipping 1.
Objec+.ives The objec:ives of this area of the inspection were to verify that:
'O @ r' D O ]D" @g b n
M& l]Jd i
W "i 5
Handling, storage and shipping operations are conducted in such a way as to give assurance that damage or deterior-scion will not occur.
The manufacturer's system meets the requirements of Criterion IIII, 10 CFR 50, Appendix B.
24 of Accomplishment
- eceding objectives were accomplished by:
leview of the ASME Section III, Division I, Class I, Quality
,ssurance Manual, dated February, 1978, Section 14 Handling, torage, Shipping and Preservation, which established the general equirements for handling, storage, and shipping.
eview of the Project Design Specification for Control Element rive Mechanisms for Tennessee Valley Authority,14074-MD-03 1, Revision 3 and Design Specification for Control Element rive Mechanisms, SY580-MD-0311, Revision 2, which established he design requirements.
sview of procedures for Cleaning, Drying and Wrapping of tainless Steel, Inconel, Stellite and Carbon Steel Components id Assemblies, Mfg-20-06EW, Revision 3 and General Procedure for
- mponent Inspection for Plating, Surface Defects and/or Clean-iness and Packaging, QC-21-01EW, Revision 3 which established
)ecific requirements.
tspection of several lots of finished and pocessed materials t storage and packaged for shipment.
- 3. g viations ne.
11owup I*ani e design specification invokes ANSI 45.2.2.
This ANSI stand-d requires plugs and caps used for shipping of stainless steel be nonhalogenerated material.
C.E. has agreed to have this idence on file by the next inspection.
This item will be dressed in the next inspection.
6 F.
Exit' Interview The inspector met with canagement representatives (denoted in paragraph A) at the conclusion of the inspection on September 12, 1980.
