Functional or Program Areas Inspected
.
1.
Reactor Coolant Pressure Boundary Piping - Review of Quality Assurance
Procedures (Units 1 and 2 )
The inspector reviewed the General Electric Company Installation and
Service Engineering Division (I&SE) Corporate Region Nuclear Quality
Assurance Manual dated June 27, 1978, including Perry Site addendum
dated December 2, 1979, and thirteen I&SE procedures relative to the
Reactor Coolant Pressure Boundary Piping work activities. These
procedures included site procurement documents requirements and con-
trol; receiving inspection; material control;
identification; clean-
liness control; erection and installation. The inspector determined
that the procedures meet the PSAR commitments, Quality Assurance
Manual, 10 CFR 50, Appendix B, and the applicable code requirements.
No items of noncompliance or deviations were identified.
2.
Reactor Coolant Pressure Boundary Piping - Welding Procedures Specifica-
tions and Quality Assurance Procedures (Units 1 and 2)
The inspector reviewed the I&SE Corporate Region Nuclear Quality
Assurance Manual dated June 27, 1978 including Perry Site addendum
uated December 12, 1979, and sixteen I&SE procedures relative to the
welding of Reactor Coolant Pressure Piping. These procedures includ-
ed weld data sheets, including hold points; qualification of welding

procedures, welders and inspection personnel; control of preheat and
interpass temperature and control of welding materials. The inspector
determined that the procedures met the PSAR commitments, Quality
Assurance Manual, Appendix B, and the applicable code requirements
except the following procedures require clarification, generation
and/or consideration of improvements.
a.
Conflicting weld bead width criteria in procedures Nos. GEP-
IP-0005 and GWP-1000.
b.
Clarification of how return welding materials are handled.
c.
Consideration of documenting welding parameters when monitored
by QC personnel.
'
d.
Issuance of weld repair, calibration, and other procedures as
required by Perry Site addendum to I&SE QA Manual.
This item is considered unresolved pending a review during a subsequent
inspection (50-440/80-08-01; 50-441/80-08-01).
No items of noncompliance or deviations were identified.
3.
Safety Related Piping - Observation of Work and Work Activities
(Units 1 and 2)
The inspector observed the following safety related piping work
activities:
a.
Rigging and protection of Unit 1 Residual Heat Removal System
Spool No. 1E12-G-RH-168-AB.
b.
Fit-up and alignment of Unit 2 Emergency Closed Cooling System
weld No. 09 on isometric drawing No. 2-P42-41.
c.
Fit-up and alignment of Unit 1 Residual Heat Removal System weld
No. 09 on isometric drawing No. 1-E12-40.
The inspector determined that work activities were performed in ac-
cordance with the applicable procedures and good construction prac-
tices were adhered to.
The inspector also observed a lamination like
defect adjacent to weld No. 09 on isometric drawing No. 1-E12-40.
The defect was investigated and removed by grinding. The inspector
observed the liquid penetrant examination after grinding and verified
the defect has been completely removed. However, subsequent ultrasonic
examination indicated the minimum wall thickness has been violated.
Nonconformance Report was initiated and weld No. 09 was cut and 12"
of the the base metal was replaced.
No items of noncompliance or deviations were identified.

Review of Documents
The inspector reviewed the following documents:
(1) The inspector established that Pullman Power Products pro-
cedures for weld material control have not been revised
since the last review (IE Inspection Report No. 50-440/79-12
and No. 50-441/79-12, paragraph 4).
(2) Receiving Inspection Report, Material Certification and
Purchase Order for E7018 electrodes with heat No. 411W3241
and lot No. 026B23; heat No. 422T0431 and lot No. 026B10;
heat No. 02M558 and lot No. 026B26; heat No. 412W3931 and
lot No. 026B22; E70S-2 K Insert with lot No. 3702B131 and
E70S-6 wire with heat No. 655T388.
It was determined that:
(a) The material test report for the E7018 electrodes with heat
No. 411W3241 and lot No. 026B23 indicated one (1) as welded
specimen has a lateral expansion of 23 mils, two (2) stress
relieved specimens, one has a lateral expansion of of 14
mils and the other 30 mils.
147 lbs. of this material was
received at the Perry site on August 9, 1977. The inspector
was informed that 21 lbs. of this material is unused and
six (6) 48" diameter x 3/8" thick wall, ASME Section III,
Class 3 pipe weld in the Plant Foundation Underdrain System
were welded with this material.
(b) The material test report for the E7018 electrodes with heat
No. 422T0431 and lot No. 026B10 indicated that one (1) as
welded specimen has a lateral expansion of 22 mils.
100 lbs.
of this material was received at the Perry site on August 9,
1977. The licensee stated that the majority of this material
was used in the non-safety related system and the rest of
this material was used in the test booth.
(c) The material test report for the E7018 electrodes with heat
No. 02M558 and lot No. 026B26 indicated one (1) stress re-
lieved specimen has a lateral expansion of 20 mils.
100
lbs. of this material was received at the Perry site on
August 9, 1977. The inspector was informed that all this
material is unused and will be used in test shop only if
used in the future.
(d) The material test report for the E70S-6 wire with heat
No. 655T388 indicated two (2) as welded specimen, one has
a lateral expansion of 11 mils and the other 27 mils. The

lateral expansion of the three (3) stress relieved speci-
mens are 31, 28, and 28 mils.
10 lbs. of this material was
received at the Perry site on August 9,1977. The inspector
was informed this material was used on four (4) 48" diameter
3/8" thick wall, ASME Section III, Class 3 pipe welds in
the Plant Foundation Underdrain System.
(e) Purchase Order No. 19-04-00-76-15 does not specify the
appropriate codes or standards but stated that wire chemis-
try was to conform to G.E. Specification No. B50A533.
However, the material tett report indicated the material
failed to meet the GE specification chemical requirements;
nonetheless, ASME Section II chemical requirements were met.
This condition represents an item of noncompliance as identi-
fied in Appendix A (50-440/80-008-02; 50-441/80-0802).
b.
Control of Materials
The inspector toured PPP welding material issuing station loc-
ated at the intermediate building elevation 599'0".
It was
determined that (1) the welding materials are properly ident-
ified 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
approved pracedures.
Except as noted, no items of noncompliance or deviations were
identified.
5.

The inspector observed welding of Liquid Radwaste System weld No. 02
on isometric drawing No. 0-G50-50 and Residual Heat Removal System
weld No. 09 on isometric drawing No. 1-E12-40.
It was determined that
(1) work was conducted in accordance with traveler; (2) proper
welding materials were used; (3) welding procedure requirements were
met; (4) work area was free of weld rod-stubs; and (5) physical
appearance was acceptable.
No items of noncompliance or deviations were identified.
