Inspection Summary
Inspection on April 29 and May 20, 1980 (Report No. 50-456/80-05;
50-457/80-05)
Areas Inspected: Reactor Coolant Pressure Boundary and Safety Related
Piping work activities, welding, procedures and records; previously identi-
fied noncompliance item. The inspection involved 13 inspector-hours
onsite by one NRC inspector.
Results: Of the nine areas inspected, no apparent items of noncompliance
or deviations were identified in 6 areas; 3 apparent items of noncompliance
were identified in three areas (infraction - failure to perform surveil-
lance on valves in storage - licensee action previous inspection findings;
infraction - failure to meet welding procedure requirements, paragraphs 2
and 4; infraction - failure to meet storage requirements, paragraph 3).

Licensee Action on Previous Inspection Findings
(Closed) Noncompliance Item (457/78-80-01) Failure to perform surveillance
of valves: The inspector toured warehouses No. 1, 2, and 3 where valves
are stored and established that the ends of four 6" check valves stored in
Warehouse No. 3 with I.D. No. 2SI-012B, No. ISI-012A, No. ISI-012B and
No. 2SI-012A were not covered. Review of surveillance records indicated
valves were inspected quarterly from September 1978 to June 1979 for
warehouses No. I and 2 and September 1979 for warehouse No. 3.
This
condition represents an item of noncompliance identified in Appendix A
(456/80-05-01; 457/80-05-01).
During inspection on May 20, 1980 the inspector determined that action had
been taken to correct the identified noncompliance and to prevent recurrence.
Consequently, no reply to this noncompliance is required.
Functional or Program Areas Inspected
1.
Reactor Coolant Pressure Boundary Piping - Observation of Work and.
Work Activities (Unit 1)
The inspector ovserved weld end preparation of the Reactor Coolant
System weld No. M-196-LP2-FW12.
It was determined that work activi-
ties were performed in accordance with applicable procedures and
good construction practices were adhered to.
No items of noncompliance or deviations were identified.

2.
Reactor Coolant Pressure Boundary Piping - Observation of Welding
Activities (Unit 1)
The inspector observed welding of the Reactor Coolant System welds
No. M-196-LP3-FW12 and No. H-196-LP1-FW1.
It was determined that
(1) work was conducted in accordance with the traveller; (2) proper
welding materials were used; (3) work areas were free of weld rod
stubs; (4) welding procedure requirements were met; (5) physical
appearance was acceptable and (6) weld bead width of weld No.
M-196-LP3-FW12 was between 5/8" to 1".
This condition repr sents
an item of noncompliance as identified in Appendix A (456/80-05-02).
Except as noted, no items of noncompliance or deviations were identified.

Reactor Coolant Pressure Boundary and Safety Related Piping - Welding
Material Control (Units 1 and 2)
a.
Review of Documents
The inspector reviewed the following documents:
(1) Phillips, Getschow Company (PG) Procedure No. QCP-B3,
Revision 2, " Control of Material Requisitions and Purchase
Orders".
(2) PG Procedure No. QCP-B8, Revision 4, " Issuance and Control
of Welding Material".
(3) PG Procedure No. QCP-B9, Revision 1, " Receiving Inspection
of Items, Material or Equipment".
(4) Purchase Order, receiving inspection report, and material
test reports for ER308L wire with heat Nos. 462327, 743575,
742774, and 744424; ER309 wire with heat Nos. C18095 and
lot No. 29617; ER316 wire with heat No. 74781 and lot No.
32606 and ER308 wire with heat No. 01556 and lot No. 30605.
It was determined that the above documents met the PSAR,
10 CFR 50, Appendix B and the applicable code requirements.
b.
Control of Materials
The inspector toured Phillips, Getschow Company welding material
issuing station located at the Turbine Building.
It was deter-
mined that (1) the welding materials are properly identified and
segregated; (2) records are properly kept; (3) issuance and
return of welding materials are controlled in accordance with
approved procedures and (4) the temperature of the rod ovens
is maintained except weld rod oven No. 12.
The temperature of
this oven is 150 F instead of 275 F as required by the procedure.
This condition represents an item of noncompliance identified in
Appendix A (456/80-05-03 and 457/80-05-02).

4.
Reactor Coolant Pressure Boundary and Safety Related Piping - Visual
Examination of Welds (Unit 1)
The inspector visually inspected the partially completed Reactor
Coolant System weld No. M-196-LP1-FW2 and the completed Safety Injec-
tion System weld No. SI-6-FW7B.
It was determined that the weld bead
width e)ceeded the procedure requirements. This condition represents
an item of noncompliance as identified in Appendix A (456/80-05-02).
5.
Reactor Coolant Pressure Boundary and Safety Related Piping - Weld
Heat Treatment (Unit 1)
a.
Review of Procedure

welds stated in paragraphs 2 and 7 of this report and determined
that preheating and monitoring methods are specified and acceptable.
b.
Observation of Preheating
While observing welding activities for items stated in para-
graphs 2 and 7 of this report, the inspector determined that
preheat met the welding procedure requirements.
No items of noncompliance or devitions were identified.
6.
