.'(5) LPurchase' Order, Receiving Inspection Report, and' Material
Certification for E7018 welding rods with lot No. 02-1-D902R
and heat No. 402H9361, lot No. 02-2-C802P and heat No.
432B5961,. lot No. 02-2-B827P and heat No. 53119, E70S-2
welding rods with heats No. 065304, No. 065150, and No. 065163.
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 the weld rod issuing station located at the
Turbine Room and the trailer.
It was determined that (1) the
welding materials are properly identified and segregated; (2)
- the temperature of the rod ovens is maintained; (3) records are
-properly kept and (4) issuance and return of welding materials
are controlled in accordance with the approved procedure.
No items of noncompliance or deviations were identified.
2.
Reactor Coolant Pressure Boundary Piping - Observation of Welding
Activities
The inspector observed the following welding activities:
Reactor Coolant System Weld No. 2-BB-01-F204 on drawing No.
a.
M-03-BB01.
b.
Reactor Coolant System Weld No. 2-BB-01-F404 on drawing No.
M-03-BB01.
Reactor Coolant System Weld No. 2-BB-01-F302 on drawing No.
j
c.
M-03-BB01.
It was determined that (1) work was conducted in accordance with
l
traveler- (2) proper welding materials were used; (3) welding pro-
cedure requirements were met;-(4) work area was' free of weld rod-stubs;
(5) physical appearance was acceptable and (6) the welder welding on
,
weld No. 2-BB-01-F404 had some of the welding rod in a welding rod
l
pouch. .The condition is an item of noncompliance identified in
Appendix A.
(483/80-02-01)
i
Except as_noted, no items of noncompliance or deviations were
identified.

mined that work activities were performed in accordance with the.
,
applicable procedures and good construction practices were adhered
to.
'
No items of noncompliance or deviations were identified.
4.
Reactor Coolant Pressure Boundary Piping - Visual Examination of Welds
a.
. Visual Examination
The inspector visually examined the following completed welds:
(1) The outside surface of the Reactor Coolant System Welds
-No. 2-BB-01-F202, No. 2-BB-01-F203 and No. 2-BB-01-F303 on
drawing No. M-03-BB01.
(2) The inside surface of the Reactor Coolant System loop 4,
weld No. 2 on drawing No. 26215-SCP, sheet 10.
It was detetmined that (1) weld surface finish and appearance
were acceptable and there was no evidence of wall thinning d.ae
to grinding; (2) are strikes and weld spatter were not evidence
and (3) there is some form of a linear indication on the inside
surface of loop 4, weld No. 2.
The indication is located at
approximately 9 o' clock to 1 o' clock when looking out from the
inside of the Reactor Vessel. The inspector also reviewed the
radiographic films and the liquid penetrant report but neither
the films nor the report showed the indication. The inspector
stated that this matter is considered unresolved pending a
review of a disposition report from Westinghouse and a written
acceptance of Westinghouse's disposition from the licensee.

b.
Review of Records
,
,
The inspector reviewed Weld Control Record of the Reactor
'
Coolant System Welds No. 2-BB-01-F202, No. 2-BB-01-F203 and
No. 2-BB-01-F303 on drawing No. M-03-BB01.
It was determined that (1)-the records indicated specified inspec-
tions were completed; (2) records are clear and legible and (3) purge
' dam removal, visual examination, and NDE have not been performed.
'
No items of noncompliance or deviations were identified.
