i
-
placement, orientation, alignment, mounting (torquing of bolts and
expansion anchors), flow direction, tolerances, and expansion
clearance.

procedure IX-48, " Equipment Installation." Paragraph
7.1 of PPP procedure IX-48 states in part that QC is responsible for
verification of items that fall within the scope of ASME (I.E. NF bolting,
pressure boundary bolting, etc...).
The field engineer is responsible for

verification of other items, including cleanliness inspections (all codes)
!
during installation. A review of PPP procedure X-11, " Visual Inspection,"
l
was also conducted.
Paragraph 3.1 of PPP procedure X-11 states in part
I
that certification of all personnel performing general visual inspection
i
shall be in accordance with ANSI N.45.2.6 and PPP QA procedure II-4,
)
entitled " Inspection and Test Personnel." The inspector determined that a
i
control inspector was not utilized to document inspections of the work
performed on the centrifugal charging pumps which are ASME safety-related
,
equipment and that the field engineer who signed-off the process sheets in
'
the block (hold for PPP inspector) was neither a QC inspector nor was the
individual certified for performing visual inspections. This matter will
be identified as violation 50-425/87-36-01, " Failure to Follow
Procedures."
During the above inspection the inspector also identified the following
concerns:
1) PPP field process sheets contain one block for PPP
inspectors to sign for hold points.
The above item has identified that
field engineers also sign-off in the block for their hold points.
Since
,
there is only a check in the block for a hold point it is left up to
1
personnel
in field to decide whether the check is for a quality control
l
or held engineer hold point. These two types of check offs should be made
distinguishable.
2.) PPP procedure 1X-48, paragraph 7.1, states in part
that QC is responsible for verification of items that fall within the
scope of ASME (i.e. NF bolting, pressure boundary, etc.).
PPP procedure
IX-5, " Bolting Procedure," paragraph 6.3.2, states in part that the field
engineer shall inspect the bolted connection prior to torquing to enture
flange alignment is acceptable and shall verify that the recommended
,
i
torquing sequence is followed and that the torque reached is in accordance
with recommended values.
Also, discussions with QC inspectors in the
field
confirmed that they are not required to verify torquing of ASME
pressure boundary pipe.
The above two PPP procedures appear to be in
conflict with one another regarding QC's function to inspect torquing of
ASME pressure boundary pipe.
3). QC and field engineering are both using
a single checklist for recording their inspection results or verifications
by initials in the same columns titled "PPP Inspection and date," making
it appear to a reviewer that QC had inspected each line item, whereas they
had not.
12. Safety Related Pipe Support and Restraint System - Unit 2(500900)
Periodic random inspections were conducted during the inspection period to
observe construction activities during installation of safety-related pipe
supports to determine that the following work was performed in accordance
with applicable codes, NRC Regulatory Guides, and licensee commitments:
Spring hangers were provided with indicators to show the approximate
-
" hot" or "coldd position, as appropriate.
I
No deformation of forced bending was evident.
-
Where pipe clamps are used to support vertical lines, shear lugs were
-
welded to the pipe (if required by Installation Drawings) to prevent
slippage.
