_
^
r
, Spacer shims used on the Plenum assembly shipping container
were not accour.ted for prior to the final assembly of the
internals.
This has resulted in a completed assembly with the

contractor unable to account for two (2) of the shims.
The problem has been identified on DR555.
An additional inspec-tion is planned by licensee.

Scope of Inspection
_
The inspector stated that the purpose of this trip was to inspect
'
the completed work and the work in progress on the Reactor Pressure Vessel internals assembly and to inspect the implementation of the
-
,
the various procedures used to control the activities throughout stages of work.
.
B.
Clean Areas for Assembly of Reactor Pressure Vessel Internals An inspection was made of the clean room assembly areas relative to the implementation of cleanliness control procedure 9A-127/C6.
No items of noncompliance were identified.
(Details, Paragraph 2)
C.
Procedures for Reactor Pressure vessel Internals An inspection was made of six (6) procedures which are used to control the work activities throughout the period of receiving inspection, unloading, handling, placement, asse=bly, welding, visual inspection and cleanliness control.
No items of nonco=-
pliance were identified.

D.
c'e'ountability of Spacer Shims' Used Durina; Shipment
'
The inspector stated that he was informed of two (2) shims approx-imately 2"x4" used in the Plenum Assembly shipping container which could not be accounted for, and that the licensee's representative had issued DR555 to identify tl.e problem and specify actions to resolve the problem. The inspector stated that a review of the working procedures showed that the words in the procedure, if
-

[ Accountability'ofSpacerShimsUsedDurineShipment Procedure P.Q.C. 245 Rev. 2 states, " Remove, collect and inventory
-
all foreign objects that were attached to or temporarily installed
,
in or around the plenum assembly for shipping aids".
The Core
Support Shield, which is the mating piece, has the same require-
- ment. Prior to assembly of the two parts, Seq. 2.27.1 states, "At this time Q.C. shall compare the inventory list of foreign objects for the Plenum Assembly and the inventory list of foreign objects for the Core Support Shield with the documented installation records sent with the internals container.
These two sets af records must be in total agreement with all foreign objects..
accounted for."
.
This activity was not performed until af ter the assembly was com-pleted. When the inventory lists were compared it was determined that the 25 shims were listed on the packing list as being installed and the receiving records indicated that 23 shi=s were found.
DR
- 0555 was issued by UE&C which documented the missing shims and'"

The inspector was informed that a thorough inspection is planned after the assembly is placed in the Reactor Pressure Vessel and the upper plenum assembly is removed.
This vill make the internals more accessible for the search. DR #0555 was issued by UE&C which documented the missing shims and requires corrective actions prior
