Unresolved Items
Unresolved items were not identified during the inspection.
5.
Safety-Related Pipe Supports and Restraints Systems (50090, 25528, 25529)
a.
Observation of Work and Work Activities
The inspector selected the following four hangers / supports in the area
of dynamic pipe supports and components supports structures that had
i
been QC final
inspected.
Documentation for the installation,
inspection and design were reviewed; the hangers were reinspected with
the assistance of QA/QC inspectors; and the results discussed with the
QA/QC inspectors to determine the effectiveness of the hanger program.

The above hangers were reinspected against their detail drawings for
configuration, identification, fastener / anchor installation, clear-
ances, member size, welds, and damage / protection.
In general, the
hangers were installed in accordance with design documents with the
exception of the items identified by the inspector listed below.
l
~ The inspector observed that for V1-1301-138-H003 and V1-1301-108-H001,
the springs had not been set at this time and therefore there was no
tension on the springs.
i
Within the areas examined, no violations or deviations were identified.
b.
Review of QC Documentation and Records
The inspector selected the following sample of four hanger / support QC
documentation packages in the area of dynamic pipe support and
component support structures that had been QC final inspected and final
QA reviewed.

The inspector observed in the Pre-Op Testing Shop, the functionally
testing of mechanical snubbers.
The test observed was the " Tension
t
Functionally Test" for a Anchor-Darling AD-15 snubber for hanger
.
l
V1-1301-198-H001. The test procedure used was GPC Procedure 28310-C
R/2. While inspecting the storage of the snubbers in this area, it was
cbserved that various small component parts for the snubbers had no
i
heat numbers, serial
numbers or other traceable markings.
This was
brought to the attention of both the licensee and a QA/QC inspector
4
f rom PPP. This concern is addressed in further detail in paragraph
5.e.
.
d.
The inspector toured the main warehouse and temporary storage area for
snubbers, in the pre-op testing area for snubbers. During tSe tour of
the main warehouse, it was noted that Pacific-Scientific snubbers
V2-1305-057-H003(2), and V2-1201-049-H023 were not being stored in
1
accordance with ANSI standards, in that ANSI N45.2.2-1972, Package,
Shipping, Receiving, Storage and Handling of Items for Nuclear Power
Plants, paragraph 6.3.2, requires that ". . . items stacked for storage
be arranged so that racks, cribbing or crates are bearing the full
weight without distortion of the item." The inspector observed that a
crate of three Pacific-Scientific PSA-35 snubbers were placed on top of
three uncrated PSA-35 snubbers.
This is contrary to GPC Procedure
GD-A-30 " Receipt, Receipt inspection, Storage and Handling," paragraph
8.6, which states " arrange items stacked for storage so racks, cribbing
'
or crates are bearing the full weight without distorting the item."
,
This failure tc protect the snubbers, noted above, is identified as
t
!
another example of violation reported in NRC Report No. 50-424/85-62;
Item No. 50-424/85-62-01, " Improper Storage of Piping Materials."
The inspector discussed the above matter with the licensee.
The
i
licensee indicated that they would address the issue of improper
storage of the snubbers with the response to violation 50-424/85-62-01,
" Improper Storage of Piping Materials."
e.
As identified in NRC Inspection Report 50-424/86-10 and 50-425/86-05,
this inspector noted that various component parts for mechanical
snubbers did not have any identification numbers, heat numbers, serial
4
numbers, or manufacturer markings t'o de able to ascertain traceability
'
of the components, and opened unresolved items 50-424/86-10-01 and
50-425/86-05-01, " Traceability of Components for Mechanical Shock
!
Arrestors."

During this follow-up inspection of mechanical snubbers, in the Pre-Op
Testing Area, Main Warehouse, and the Pre-Fab Shop, this inspector was
looking for the traceability of small component parts used in the
fabrication and installation of the mechanical snubbers. In particular
the snubbers' load pins and studs, bolts, nuts, and hardened washers.
Many examples of the components in question, were identified by this
inspector as not having any identifying markings on the components.
The findings were identified in all the three storage areas noted above
and identified to the licensee.
As required by Pullman Power Products (PPP), SI-64, " Site Instruction
for Marking of Pipe Supports", Section 5.1, states, " Materials which
are considered small products bolting material (studs, nuts and bolts
2" nominal diameter and less)
and materials supplied with a
...
l
certificate of compliance without marking identifying the items to the
!
manufacturer must be marked as required in section 6.1".
Section 6.1
states, " Materials not marked individually by the manufacturer are to
be marked as follows:
Bergen Paterson
-
NF-BP1
Pacific Scientific -
PS1
Anchor / Darling
-
AD1
t
Also, PPP procedure VIII-1, " Identification of Materials, Parts &
Components", Section 5.1,
states, " Markings Required by the Codes,
Specifications and Procedures Referenced in Paragraph 3.0 Shall be
Verified During the Receipt Inspection Required by Project Procedure
X-5, Field Receiving Inspection."
During the inspection of hardened washers, this inspector noted that
four different sizes were being utilized in the torquing process of
mechanical snubbers in the Pre-Fab Shop.
The inspector noted to the
licensee that the smallest of the four washers had no identi fying
markings and did not fit in the parameters as stated in PPP Procedure
VIII-1, " Identification of Materials, Parts & Components," Sect on 5.2,
i
which states "The identification of hardened washers shall be verified
by color of the washer and the sound it emanates when dropped on a hard
surface. .The color hardened washers is black or dark gray (from the
heat treatment to improve physical properties). The sound is resonant
versus the muted sound of standard unhardened washers."
Upon further investigation and review, unresolved item 50-424/86-10-01
and 50-425/86-05-01, " Traceability of Components for Mechanical Shock
Arrestors", is being closed as an unresolved and opened as violation.
The discrepancies in the use of small components in the installation
and fabrication of mechanical snubbe
were not being followed as noted
a
above and is contrary to the proct Jures as noted, and as required by
Criterion V of Appendix B to 10 CFR Part 50, " Instructions, Procedures
and Drawings," and is identified as violation 50-424/86-20-01 and

Licensee Identified Items
(Closed) Item 424, 425/84-54, " Potential Deficiency on Pacific-Scientific
PSA-1 and PSA-3 Shock Arrestors" (10 CFR 50.55(e)).
The final report was
submitted on July 3, 1984. The report has been reviewed and determined to
be acceptable.
The inspector held discussions with responsible licensee
representatives, reviewed supporting documentation and correspondence to
verify that the corrective actions identified in the report have been
completed.
