Licensee Action on Previous Inspection Findings
,
(Closed) Noncompliance Item (454/79-02-02; 455/79-02-01) - Control of
welding material: The inspector reviewed the randomly selected weld
material issuance slips and determined that returned unused materials
wer' marked on the slips.
(Closed) Unresolved Item (454/79-12-01; 455/79-12-01) - Pipe storage: The
inspector reviewed the pipe storage surveillance report which indicated
that the storage conditions were corrected.
(Closed) Noncompliance Item (454/79-12-01) - Weld data sheet hold point:
The inspector reviewed the nonconformance report and determined it was
properly closed.
(Closed) Noncompliance Item (454/79-12-03; 455/79-12-02) - Control of
Document: The inspector verified that the procedure supplements have
been redistributed. The revised procedure was also reviewed.
Functional or Program Areas Inspected
1.
Peactor Coolant Pressure Boundary Piping - Observation of
Work and Work Activities (Unit 1)
The inspector observed weld end preparation of Safety Injection
System weld No. 122 on Isometric Drawing No. SI-6 and Spool No. SI-1

on Isometric Drawing No. SI-1-4. It was determined that work activities
were performed in accordance with the applicable procedures and good
a
construction practices were adhered to.
No items of noncompliance or deviations were identified.
2.
Reactor Coolant Pressure Boundary Piping - Review of Quality Records
The inspector reviewed the Westinghouse Corporation Quality
a.
Release, ASME data Report and Receiving Inspection Report for
the following piping spools:
(1) QR No. 35627 for spool No. CBE-Loop-1-6
(2) QR No. 35628 for spool No. CBE-Loop-2-1
(3) QR No. 35630 for spool No. CBE-Loop-2-6
(4) QR No. 31246 for spool No. CAE-Loop-2-1
(5) QR No. 31244 for spool No. CAE-Loop-3 f
(6) QR No. 35633 for spool No. CBE-Loop-3-6
(7) QR No. 35634 for spool No. CBE-Loop-4-1
(8) QR No. 35635 for spool No. CBE-Loop-4-6
-
It was determined that the documents are legible and acceptable.
b.
The inspector reviewed the pipe storage inspection records for
the period between February 1978, and August 1979. It was
determined that (1) the records are difficult to retrieve; (2)
inspection was performed at the required frequency and (3)
storage requirements were met.
The inspector reviewed the following CECO audit reports:
c.
(1) CECO Audit Reports No. 6-79-201, No. 6-79-215, No. 6-79-180
and No. 6-78-160.
(2) CECO reports of audit performed at Westinghouse Corporation,
Monroeville for years 1977, 1978.
It was determined that the records are acceptable and findings
were closed out in a timely manner. However, the audits at
Westinghouse were performed by CECO home office personnel hence
not all the supporting documents, such as follow-up actions,
checklists used during the audits, were available on site. The
licensee stated those documents can be made available, including
the 1979 audit report, on site. This matter is considered unre-

No items of noncompliance or deviations were identified.
3.
Reactor Coolant Pressure Boundary Piping - Observation of
Welding Activities (Unit 1)
The inspector observed the followlag welding activities:
a.
(1) Reactor Coolant System, Weld No. 219 on isometric drawing
No. RC-1-1, Welds No. 82 and 83 on isometric drawing
No. RC-1
(2) Safety Injection System, Weld No. 109 on isometric drawing
No.
SI-1.
It was determined that (1) work was conducted in accordince
with traveler; (2) proper welding materials were used; (3)
welding procedure requirements were met; (4) work area was free
of welding rod-stubs; (5) physical appearance was acceptable
and (6) weld end detail for weld No. 219 on isometric drawing
No. RC-1-1 was not specified and accepted by QC inspector based
on no acceptance criteria. This condition is an item of noncom-
pliance identified in Appendix A. (454/79-16-02)
b.
The inspector observed liquid penetrant examination of Safety
.
Injection System, Weld No. 141 on isometric drawing No. SI-5
