SUMMARY Inspection on June 26-29, 1979 Areas Inspected This routine unannounced inspection involved 33 inspector-hours onsite in the areas of steel structures and supports; reactor coolant loop piping and other safety related piping - Welding Procedures Specifications and Quality Assurance Procedures; weld material control; NDE activities.
Results Of the 5 areas inspected, no apparent items of noncompliance or deviations were identified in 3 areas; 2 apparent items of noncompliance were found in 2 areas.
Welding Material Control - Infraction -Failure to control calibration on electrode ovens (paragraph 5); Weld Procedure Specifications and Quality Assurance Procedures -
Deficiency - Failure to include nonessential variables in GTA & GMA welding procedures (paragraph 6).

Burner, Manager Welding Quality Control Other licensee employees contacted included 10 construction craftsmen, 5 technicians, and 4 office personnel.
- Attended exit interview 2.
Exit Interview The inspection scope and findings were summarized on June 29, 1979, with those persons indicated in Paragraph 1 above. The inspector identified the areas inspected, and discussed in detail the two items of noncompliance.
No dissenting comments were received from the licensee.
3.
Licensee Action on Previous Inspection Findings Not inspected.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort The inspector conducted a general inspection of the spray ponds, reactor base mats, auxiliary building, concrete batch plant, fabrication shops, weld material issue stations, and warehouse facilities to observe construc-tion progress and construction activities such as excavation, drilling, powder setting, blasting, cadwelding, stud welding, concrete placement and testing, material handling and control housekeeping and storage.
a.
The inspector witnessed magnetic particle examination in progress on a flange to pipe joint in the Component Cooling Water (CCW) System to determine surface suitability and the specified NDE being performed with qualified personnel.

b.
The inspector observed activities at weld material issue. stations to determine adequacy of; weld material storage / segregation, oven temper-atures, issue records and return of unused weld material. The inspector also observed work areas for uncontrolled weld material.
During observation of the weld material issue stations on June 27, c. _1979, the inspector noted many electrode stubs and damaged electrodes on the ground adjacent to the disposal containers.
The licensee indicated the condition would be corrected, on June 28, 1979 however, the inspector, noted that the corrective action had not been fully implemented.
The inspector stated that this area will be checked again on a future RII inspection and was identified as inspector followup item no. 553-554/79-07-01.
d.
On June 27, 1979, in Weld Material Issue Station No. 1, the inspector noted an electrode issue oven in use with a past due calibration sticker for its thermometer, and an electrode baking oven not in use with a past due calibration sticker was not tagged " Hold, Not To Be Used Until Calibrated". CEP-12.01 Revision 4 dated 12-22-78 " Control of Measuring and Test Equipment" paragraph 2.4, requires equipment past due for calibration not to be used and to be so tagged.
This is in noncompliance with 10 CFR 50 Appendix B Criterion V.
This is an infraction and was identified as item no. 553-554/79-07-02.
6.
Steel Structures and Supports - Welding Procedure Specifications and Quality Assurance Procedures Requirements control, preparation, qualification, approval / certification distribution and revision of welding procedure specifications (WPS) are established through CEP 9.03 Revision dated 10-12-77 " Qualification of Welding Procedures" and CEP 6.03, Revision 2 dated 5-4-79 " Distribution of Design Information".Section III and IX of the ASME Code 1974 with sumn.er 1974 addenda controls the qualification of WPS applicable to steel structures and supports.
Six randomly selected WPS involving automatic gas metal arc welding (AGMAW),
gas metal arc welding (GMAW) and shielded metal arc welding (SMAW) were selected for review. These were as follows :
WPS Process GMA-11-5-1A Rev 1 AGMAW GMA-11-B-4 Rev 1 AGMAW GM-88-B-2 Rev 1 GMAW

~
SM-18-B-1 Rev 1 SMAW SM-11-B-9 Rev 2 SMAW Each of the above WPS(s) and their supporting Procedure Qualification Records (PQR) were reviewed to ascertain whether essential, supplementary and/or nonessential variables including thermal treatment were consistent with code requirements; whether WPSs were properly qualified and their supporting PQRs were accurate and retrievable; whether all required mechanical tests had been performed and the results met the minimum requirements; whether the PQRs had been reviewed and certified by appropriate personnel and, whether any revisions and/or changes to nonessential variables were noted.
Within the areas examined the inspector noted on June 28, 1979, that for the GMAW, GTAW (discussed in paragraph 7) and AGMAW procedures and their supporting PQR, the nonessential variable " width, frequency, or dwell time of oscillation", QW-410.7 of the ASME Code Section IX, was not addressed as required by Paragraph QW-201.1 of ASME Code Section IX. The licensee's representative stated that the missing variable was not applicable and therefore was omitted, however he agreed to take appropriate corrective action in this matter.
Failure to include all pertinent information in the welding procedure specification is in noncompliance with 10CFR50 Appendix B Criterion IX.
This is a deficiency and was assigned i+ m number 553-554/79-07-03.
7.
Reactor Coolant Loop Piping and t ae. Safety Related Piping - Welding Procedure Specifications And Quality Assurance Procedures The control and code requirements are the same as paragraph 6 above.
Five randomly selected WPSs involving GTAW, GMAW and SMAW or a combination GTAW, GMAW, and SMAW were selected for review.
These were identified as follows:
WPS Process GT-11-0-1 Rev 5 GTAW GT-88-0-1 Rev 5 GTAW GT-SM-11-0-3 Rev 7 GTAW-SMAW j}'b GT-SM-88-0-1A Rev 5 GTAW-SMAW GT-GM-11-0-3B Rev 0 GTAW-GMAW The inspection results of paragraph 6 above also apply to the inspection of wpld procedure specification in paragraph 7
