Inspection Summary:

Inspection on October 10-13,1978 (Report No. ' 50-445/78-18; 50-446/78-18)

Areas Inspected: Routine, unannounced inspection of construction activities including review of quality assurance implementing procedures related to reactor coolant piping (Unit 1); observation of work activities related to welding of the reactor coolant piping (Unit 1); observation of work activi-ties related to welding of safety related piping (Unit 1); review of records related to containment structural welding (Unit 1); observation of work and review of records related to containment exterior wall concrete placement (Unit 1); and review of records related to the personnel air lock installa-tion (Unit 2). The inspection involved fifty-one inspector-hours on-site by two NRC inspector Results: Of the seven areas inspected, no items of noncompliance were identified in six areas. One item of noncompliance was identified in the other area (infraction - failure to follow welding procedure - paragraph 3.b).

The IE inspectors also interviewed other contractor employees during the course of the inspectio * denotes those present at the exit intervie . Site Tour The IE inspectors toured the various areas of the site to observe ;

construction activities in progress and to inspect housekeepin During the tour, the number and revisions were recorded for two drawings observed at El 831'-6" in the Unit 1 Safeguard Buildin Subsequent comparison with the site Document Control Center indi-cated that one of the drawings in the field was not the current revisio Revision Control DCC Current Drawing in Field Number Revision El 0717-S 1 044 1 S 0901 2 044 3

Document control records indicated that Revision 3 to drawing S-0901 had been issued to the field on September 23, 1978. The field drawings previously observed could not be relocated in the field for reverifi-cation of revisions by the IE inspecte This matter is considered unresolved pending verification of the field drawing status by the licensee to determine the status of the observed drawing. Further inspection in this area will be performed during a subsequent inspection to determine the effectiveness of the licensee's drawing control . Reactor Coolant Pressure Boundary Piping - Unit 1 Review of QA Implementing Procedures The IE inspector reviewed the B&R QA manual and selectively examined the following quality related procedures issued by B&R to cover purchase, receiving inspection, storage, hand-ling, installation and cleaning of reactor coolant pressure boundary piping:

Procedure MEI-6, Rev. O, " Engineering Data for Preparation of Component Support Travelers" Procedure MEI-8, Rev. O, "NSSS Cleanliness Control During Coolant Loop Installation" Procedure PCI-001, Rev.1, " Pipe Department Cleanliness Control" Procedure CPM-10.4, Rev. O, " Cleanliness Control" Procedure CPM-6.3, Rev. 3, " Preparation, Approval and Control of Operation Travelers" Procedure CPM-6.8, Rev. 0, " Fabrication and Installation of Component Supports, including ASME III" In the areas inspected, no discrepancies with the requirements of Section III of the ASME B&PV Code were note No items of noncompliance or deviations were identifie _ . . . - . . .-. - _ _ -

'

The IE' inspector observed welding being performed on field welds FW-15 and FW-16, Dwg BRP-RC-1-520- FW-15 and FW-16 are the butt welds connecting the " cold leg"' pipe spool of Loop 2 to the' t reactor coolant pump and reactor vessel, respectivel ;

A welder was monitored, while welding FW-15, for conformance to the welding variables. specified.in WPS 88025, Rev. O and ICN The amperage, voltage, and travel speed were observed to be with-in the requirements of the welding procedure specificatio The automatic welding being accomplished on FW-16 was monitored for compliance with the requirements specified in WPS 99028, Rev. O for welding variables.- The amperage and voltage were observed to be within the' ranges permitted by the welding pro-cedure specification. The travel speed was observed to'be~

2.5 inches per minute; whereas the travel speed required by WPS 99028, Rev. 0 was 4-6 inches per minut Failure to follow the welding procedure. specification with respect to travel speed appears to be in noncompliance with the requirements of 10 CFR Part 50, Appendix B, Criterion ' Safety Related Piping - Unit 1 The IE inspector observed the following operations for fabrication welding of safety related piping:

Fitup of FW-31, thy) BRP-DD-1-YD-20-1 and FW-6, Dwg BRP-SI-1-YD-03-0 ,

Root weld of FW-13, Dwg BRP-FW-1-17-RB-03-0 and FW-6 Dwg BRP-SI-1-YD-03-0 ,

1 Installation of Cable Tray Hangers - Unit 1

<

The IE inspector visually inspected the~ installation welds for four ,

cable tray hangers, Mark Nos. 42, 227, 229 and 1213. Review of

- inspection' records, records of welding variables checks, welder qualifications, and nonconformance reports indicated that the welds and documentation were in accordance with Gibbs & Hill Specifications ES-100 and SS-16B and Brown ~ & Root Procedures ECP-10 and CP-QP-1 No discrepancies with these requirements were note No items of noncompliance or' deviations were identifie .. . .c Containment Exterior' Wall - Unit 1 The IE inspector observed a portion of concrete placement number 101-5805-026 for the containment exterior wall. This placement included the circumference of the containment exterior wall from elevations 955 to 961. The IE inspector observed preplacement clean-liness ano form integrity, concrete placement techniques, consoli-dation and lift height control Review of field records for con-crete temperature, air entrainment and slump tests indicated that results were within the acceptable tolerances. In the areas in-spected, no discrepancies with the requirements of Gibbs & Hill Specification 2323-SS-9 were noted, p

No items of noncompliance or deviations were identifie . Personnel Air Lock Installation - Unit 2 The Chicago Bridge and Iron records for the installation of the Unit 2 personnel air lock were reviewed. The' specific items reviewed included welder qualification, weld procedure qualification, weld material control records, weld inspection and air lock location inspection. Records reviewed did not indicate any discrepancy with Gibbs & Hill Specification 2323-SS-14.

l No items of noncompliance or deviations were identifie . Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or deviations. An unresolved item disclosed during the inspection is discussed in paragraph 2.
