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 inspectors.
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).

Site Tour
The IE inspectors toured the various areas of the site to observe
construction activities in progress and to inspect housekeeping.
During the tour, the number and revisions were recorded for two
drawings observed at El 831'-6" in the Unit 1 Safeguard Building.
Subsequent comparison with the site Document Control Center indi-
cated that one of the drawings in the field was not the current
revision.

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 inspecter.
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 controls.

Reactor Coolant Pressure Boundary Piping - Unit 1
a.
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 noted.
No items of noncompliance or deviations were identified.

Observation of' Work Activities
,
'
The IE' inspector observed welding being performed on field welds
FW-15 and FW-16, Dwg BRP-RC-1-520-2.
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, respectively.
A welder was monitored, while welding FW-15, for conformance to
the welding variables. specified.in WPS 88025, Rev. O and ICN 2.
The amperage, voltage, and travel speed were observed to be with-
in the requirements of the welding procedure specification.
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 minute.
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 V.

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
,
Balance welding of FW-3, Dwg BRP-SI-1-SB-19.0
,
Final weld surface preparation of FW-1-1, Dwg BRP-FW-1-17-
l
1303-2 and FW-4, Dwg BRP-SI-1-SB-19-0
,.
In the areas inspected, no discrepancies from the requirements of
Section III of the ASME B&PV Code'were noted.
<
No items of noncompliance or deviations were identified.

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-18.0.
No discrepancies with these requirements were noted.
No items of noncompliance or' deviations were identified.

6.
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 controls.
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,
No items of noncompliance or deviations were identified.

7.
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 identified.
8.
Unresolved Items
