2.
Site Tour The IE inspectors toured the Units 1 and 2 Reactor Containment Buildings and Auxiliary Building to observe construction activities in progress and to inspect housekeeping.
No items of noncompliance or deviations were identified.
3.
Unit 1 Reactor Coolant Pressure Boundarv Piping - Observation of Work The IE inspector witnessed part of the repair work being performed on weld joint FW-19-1 as shown on drawing SI-1-RB-037, Revision 1.
This is a piping weld on the Safety Injection system line near its juncture with the Loop No. 1 cori leg. Due to an error in fabrication by Grinell, a mismatch occurred which necessitated a weld build-up of the affected.
area.
The welding operation was accomplished in accordance with WPS-880ll, Revision 4 and WPS-860?35, Revision 3.
Weld Data Card (WDC)
56435' appeared to be correct and complete for all previous operations.
No items of noncompliance or deviations were identified.

Concrete Placement A review of Quality Assurance records relative to the Unit 2 Containment Building structural concrete was conducted to ascertain whether these records reflect work accomplishment consistent with design specifications and Safety Analysis Report commitments.
The following records for Placement No. 201-8805-006 (Unit 2 containment wall from elevation 1026 to 1032)
were specifically reviewed:
,
a.
Concrete Pour Card b.
Inspection Report
c.

Concrete Placement Summary
e.
Daily Curing Verification Record
f.
Report on Compressive Tests of Concrete
g.
Batch Tickets
In addition, fifty-two randomly selected Sieve Analysis of Aggregate
reports covering the period from October 1 to November 1, 1979, were
reviewed. The tests involved both the coarse and fine aggregates used
in the Class I concrete mix (No. 133).
The records reviewed indicated conformance with the following doci.ments:
a.
Gibbs & Hill Specification No. 2323-SS-9, Revision 5, "Concrote"
b.

Installation of Safety-Related Components - Observation of Work and
Work Activities
The IE inspector conducted a follow-on walk thru and inspection of both
Unit 1 and Unit 2 Reactor Containment Buildings and Auxiliary Building
to observe installation and protection of safety-related components.
Observations were made on all principle levels of the Reactor Containment
Buildings and the Auxiliary Building in conjunction with the requirements
prescribed by B&R Construction Procedure, " Storage and Storage Maintenance
of Mechanical and Electrical Equipment," MCP-10, Revision 4, dated
June 14, 1979, and TUSI Procedure QI-QP-11.3.31, dated January 5, 1980.
No items of noncompliance or deviations were identified.
6.
Safety-Related Components - Review of Quality Control Records
The IE inspector selected the QA/QC documents related to the containment
spray pumps, boron injection pumps, and the safety injection pumps for a
records review.
Included in the review were the "QA Data Package" files
for each of the pumps and which contained the " Certificates of Compliance";
ASME forms NPV-1 and NF-1; and transport and installation travelers
RI78-044-5701, dated August 7, 1978, and RI79-165-4800, dated May 2, 1979.
In addition, QA/QC records contained on microfiche, located by QRs No.
32724 and 34024, were reviewed.
No itens of noncompliance or deviations were identified.
