On September
9,,1983,
the Joint Intervenors filed with the Atomic Safety
and Licensing Appeals
Board
a document to supplement their pending motion
to re-open the record
on the issue of Construction Quality Assurance
(CQA).
The documents
included (1)
a proposal for an independent
audit of
Pullman Power Products
(PPP)
by Nuclear Services
Corporation
(NSC) and,
(2) the results of a previous Nuclear Services
Corporation audit.
The
NSC audit was conducted
from August 22 - September
20,
1977,
and covered
Pullman's construction activities from 1971 through September
1977.

Re ion V Actions
The Joint Intervenors'otion
and
PGSZ's
response
to the Joint
Intervenors
Supplement
to Motion To Reopen
The Record
On Construction
Quality Assurance
was reviewed by the
NRC Region
V staff,
and
a staff
response
provided to the
ASLAB on this subject
on October 4,
1983.
Based
on the review of the aforementioned
documents,
discussions
with licensee
personnel
and
a review of NRC Region IV and Region
V Inspection Reports
during the referenced
period,
(1971 through Sept>>mber
1977) the staff
concluded that the Pullman Quality Assurance
Program did not suffer a
major breakdown
and for those instances
where isolated
breakdowns
did
occur, those problems
were identified, addressed,
and resolved
by the
licensee's
Quality Assurance
Program or the
NRC inspection program in
effect at the time.
a
~
~
The staff did not attempt to reconcile each
and every
NSC audit finding.
Rather,
the staff verified that the licensee
made every effort to
throughly address,
investigate,
and resolve
each concern identified in
the
NSC audit.
However,
a review of the licensee's
response
indicated
that three areas
required further clarification to assure
that the
licensee's
response
to the
NSC audit findings complied with regulatory
and code requirements.
These
areas
of concern are discussed
below in
paragraph
4 of this report.
4.
Ins ection Results
During this inspection the inspector
met with licensee
personnel
who
participated in the April - June
1978 licensee
followup audit of Pullman
Power Products.
This audit was conducted
as
a direct result of the
audit findings and was performed to assure
that Pullman's Quality
Assurance
Program
and physical work complied with regulatory
and
'contractual
requirements
in effect during the time the work was
performed.
The results of the licensee's
and Pullman's
response
to the
NSC audit findings were reviewed with the above referenced
individuals.
The review/discussions
reaffirmed the earlier staff conclusion that the
NSC audit findings had been properly addressed,
and every affort had been
made by the licensee
to throughly address
and resolve the
NSC audit
findings.
The three areas
of concern were resolved
as follows:
a 0
Criterion III, "Measuring and Test Equipment" finding No.
2 to the
NSC audit states
that,
"The calibration program did not require
recalibration of themocouples until June
16,
1976.
Therefore,
there
is no assurance
of the accuracy of thermocouples
used for pre- and
post-welding heat treatment prior to June
16,
1976.
Newly purchased
thermocouples
were required to be calibrated by the manufacturer.
However, the manufacturer's
calibration does not assure
that the
thermocouples
have not been
damage
during handling and shipping."
The Pullman response
states,
in part, that, "All thermocouples
have
been
and are purchased
with calibration.
Prior to June,
1976, there
were no requirements
of recalibration to thermocouples.
When the
program
was initiated, all existing thermocouples
were recalibrated
and none were found to be out of calibration."
The inspector
reviewed thermocouple
record packages
and confirmed
that the documentation
supported
the licensee
response
that
thermocouples
were purchased
with calibration requirements,
and that
when all existing theomocouples
were re-calibrated
on June
15,
1976
and July 10,
1976 and that all were found within calibration
requirements.
The inspector
has
no further questions
on this subject.
b.
Criterion IX, "Special Processes"
item 10.o (2) of the
NSC audit
finding states
that,
"Tempil sticks were not used."
The Pullman response
states
that, "In cases
where welders
were noted
without Tempil Sticks in Internal Audit Findings, there
was
no
indication on the "Welders Audit Sheet" that the interpass
temperature
was too high. It is, therefore,
concluded
that, weld
quality was not affected;
Ferrite checks of welds where tempil
sticks were not used
show acceptable
results."
This
NSC audit finding may have been based
on findings. of previously
conducted
Pullman audits.
The inspector interprets
the
NSC audit
finding as implying that Tempil sticks were not used at all by
Pullman welders.
The Pullman response
makes it clear that only for
those
cases identified by the Pullman auditor was there
a question
as to whether the welders audited were using Tempil sticks.
The
inspector
found that Tempil sticks were used by Pullman welders
as
a
matter practice during the period.
The inspector
has
no further questions
on this subject.
C ~
Criterion IX, "Special Processes",
finding 10g of the
NSC audit
states
that,
"Welder BF
(W. Adair, 251) performed welding on FW-70,
72, 73, 76, 77,
78,
100B,
132;
and
133 in isometric package
21-7 and
FW-88, 90,
92,
134,
135,
and
160B in isometric package
21-8.
This
welder was not qualified for the thickness
range;
and 'the welds were
reported
on DR's
25367 2538'539'nd
2899.
In accordance
with
Pacific Gas
6 Electric Company disposition,
some of the welds were
radiographed
and found acceptable;
welder
BF was qualified to the
thickness
range;
and all the welds in question were accepted.
This
disposition is not permitted by B31.1, B31.7,
and
which all specify that the welder must be qualified prior to making
production welds."
The Pullman response
states:
The deviation cited was found by Pullman Quality Assurance
and reported to
PGGE on appropriate deviation records.
Reference
to DR-2536 is incorrect.
The auditor is completely incorrect in indicating that
ASIDE
Section IX, B31.1 and B31.7
do not permit welding prior to
qualification.
No such prohibitions exist.
DR-2538 Revision
1 and DR-2539, Revision
1 dated July,
1975
report 2-2" butt welds in Diesel Fuel Oil (160B and
100B) made
12/17/73.
Welder was not qualified for small diameter
(3"- and
under) unitl 2/28/74.
Both DR's use the option to qualify the welder by radiography
(see
1971 Section IX Winter 71 Addendum - Paragraph
Q2(a)).
Both production welds
(160B and
100B) were radiographed
and
found acceptable.
PG&E accepted qualification on this basis.
P
C
~
4
DR-2899 dated August,
19'75 reported
14 butt welds
made prior to
2/18/74.
Investigation
shows these
were
2 1/2" pipe size.
Prior qualification by DR-2538 Revision
1 and DR-2539 Revision
1 covers qualification of these
seams.
No further NDE
required..."
The inspector questioned
the response
to the finding because
the
code
does not allow a welder to perform production welding prior to
qualification to the particular process.
The inspector
considered
that to adequately
resolve this finding the licensee
should have
radiographed
the other fourteen welds in question.
Investigation
into this item determined that during the
1978
HOSGRI modifications
the diesel oil fuel piping was re-routed.
During the re-routing
process,
the two piping runs containing fifteen of the sixteen welds
in question
were eliminated.
The'only currently installed weld
(Weld No.
160B)
was
one of the two welds originally radiographed
by
the licensee
to justify the acceptance
of the other fourteen welds.
The radiographs
for weld 160B were reviewed
and found acceptable.
Additionally, the inspector noted that the original NSC audit
finding came
from a Pullman internal audit that originally
identified the discrepancy.
Therefore, it is apparent that the
Pullman Quality Assurance
Program
was in effect and was actively
identifying problems in Pullman's welding program.
The inspector
has
no further'uestions
on this subject.
