Licensee Action on Previously Identified Items
(Closed) Noncompliance Item (341/78-14-02):
Inadequate hanger inspection
corrective action. Problems continue to be identified, and a new item
of noncompliance was disclosed during this inspection.
See Paragraph 3 of
this report for details.
(Closed) Unresolved Item (341/79-03-03):
Questionable inspection program
for installed hangers. The site hanger verification program appeared
to be not doing the job as was intended.
This matter, in combination
with a previously identified noncompliance item (341/78-14-02), are
combined and form a new item of noncompliance identified during this
inspection.
See Paragraph 3 of this report for details.
(Closed) Unresolved Item (341/79-03-05):
Inadequate Procedure
Qualification Records (PQR) for Weld Procedure Specification No.
WPS-7001. The inspector reviewed WPS-7001, "GTAW and/or SMAW of P1
Material," Rev. 9, dated March 14, 1979.

Functional or Program Areas Inspected
1.
Status of QA Level I Hanger besign and Installation
As of the date of inspection, the licensee reported the following
status of activities:
a.
Final installation drawings issued by Stone and Webster (S&W)
amounted to 776. Among which 583 hangers, snubbers and
restraints are within the drywell.
b.
Among the 529 installed hangers, 280 (previously reported
375) were erected by The Ralph M. Parsons Company (Parsons),
the former site main contractor. None of these had installa-
tion and concrete anchor bolt test records. All installations
were determined not to be in accordance with the latest S&W
drawings. Among the 280 hangers, 89 will be modified to meet
requirements. Others may have to be removed.
c.
Among the 249 Wismer and Becker (WB) installed hangers, all
but 8 were inspected.
These hangers were installed prior to
S&W's issuance of the drawings. Of 249 installed hangers, 104
are included on S&W drawings.
WB is in the process of verifying
the adequacy of installation.
2.
Review of Hanger Work Procedures
WB-Q-112. " Discrepancy Trend Analysis and Reporting," Rev. 1,
a.
dated September 21, 1978.
The inspector commented that this procedure is incomplete
and requires revision prior to being used for evaluating hanger
installation and inspection problems.
This is an unresolved
item.
(341/79-07-01)
b.
WB-C-114, "QA Level I Pipe Supports (Not for GE)," Rev. 7-1,
dated February 8, 1979.
The inspector had the following comments:
(1) GE pipe hangers were excluded from this procedure;
Paragraphs 5.4 and 7.7.1 referenced and identified GE
requirements.
(2) The responsibility for engineers to verify the adequacy
of installation is shared by DI field engineers (FE).
DI FE's responsibility in this area was not specified
in Paragraph 3.

.
(3) Paragraph 8.8, clearance between plates and walls, stated,
in part, that ".
. not to exceed 1/16" over 80% of
.
the perimeter of the attachment plate. The remaining
20% of perimeter shall not exceed 1/4" clearance." The
inspector questioned the engineering justification of this
provision.
(4)
In Paragraph 10.4 the use of Design Change Requests
(DCR's) for documenting and requesting changes on as
built hanger conditions appeared to be inappropriate.
Items b(1) to b(4) are considered unresolved.
(341/79-07-02)
No items of noncompliance or deviations were identified.
3.
Review of Hanger Installation Program
A stop work order on installation of QA Level I hangers was issued
on September 8, 1978, by the WB QC Department.
Since then, corrective
actions were initiated and the stop work was lifted on October 27,
1978.
Starting November, 1978, a field engineering verification of
hanger installation program was put into effect.
They observed
installation problems beginning to increase again. The latest trend
analysis shows the hanger veld deficiency rate to be 50% with a
rising trend. A stop work order was issued on March 15, 1979, once
again to halt all QA Level I hanger installation.
This order was
issued by WB Project Engineering.
The failure to promptly identify deficiencies and to take effective
corrective action is considered an item of noncompliance with 10 CFR 50, Appendix B, Criterion XVI, and Enrico Fermi 2 FSAR, Section
A17.5.16. (341/79-07-03).
A similar item of noncompliance was
identified in RIII Report No. 50-341/78-14.
One of the main reasons for the continuing hanger problems appears
to be the lack of immediate corrective action on the part of the WB
Project Engineering when the deficiencies are identified.
The
situation extended from November, 1978, to March, 1979, approxi-
mately four months. Under the present engineering verification
progran installations were not passed on for inspection and as a
result WB QC was unable to perform its intended function.
Other circumstances permitting the present condition to exist are
(1) the lack of a licensee audit of the WB engineering hanger
verification program, (2) the lack of a procedure establishing a
hanger installation deficiency trend analysis, (3) failure to
separate the initial hanger installation inspection from final
check out and adjustments, (4) incomplete instructions from design
,
engineering on revised hanger installations, (5) WB QC's reluc-
tance to use the Deviation Disposition Request (DDR) system for
2282

fear of holding up work progress, and (6) failure to communicate and
use available installation and inspection measures such as,
as-built records, Design Change Requests (DCR), DDR's, Design Change
Notices (DCN), and Field Modification Requests OR{R).
Subsequent to the inspection, on March 21, 1978, a telephone
meeting between RIII and DECO management was held. Problem areas
identified in this report were discussed, and the licensee committed
to inform RIII of changes to the program and the progress of
corrective action.
In addition, the licensee committed to inform
RIII prior to lifting of the stop work order. This will enable the
RIII inspector to observe hanger work performed to demonstrate the
effectivness of the corrective action and the steps taken to prevent
recurrence.
Except as noted, no items of noncompliance or deviations were
identified.
Unresolved Items
Unresolved items are matters about which more Laformation is required in
order to ascertain whether they are acceptable items, items of noncom-
pliance, or deviations. Two unresolved items disclosed during the
inspection are discussed in Paragraphs 2a and 2b.
Exit Interview
The inspector met with site staf f representatives (denoted under Persons
Contacted) at the conclusion of the inspection on March 16, 1979.
The
inspector summarized the purpose and findings of the inspection. The
licensee acknowledged the findings reported herein.
