- Denotes those present at the exit interview.
The inspector conferred with other licensee and contractor personnel during the course of the inspection.
Facilit Tour The inspector observed work activities in-progress, completed work and plant status in several areas of the plant during general inspection of the plant.
The inspector examined work for any obvious defects or non-compliance with regulatory requirements or license conditions.
Particular note was taken of presence of quality control inspectors and quality con-trol evidence such as inspection records, material identification, noncon-forming material identification, housekeeping and equipment preservation, and quality inspection personnel as such personnel were available in the work area.
Reactor Pressure Vessel RPV Installation The reactor vessel with factory installed internals was stored onsite on Lampson crawler-transporters.
Removal from the storage area and trans-portation to the prepared lifting area'djacent to the containment build-ing was accomplished using the same transporters.
Lampson Twin Transi-Lifts were placed on a concrete foundation at the lift area in accordance with attachment 4. 3. 2 and 4.3. 3. to procedure LUR WP-08.
The inspectors observed a portion of the activities associated with lift-ing of the RPV and placement in its permanent location in the containment building.
The liftwas governed by Lampson procedure number LUR WP-08 Revision 2.
The inspector's observations
'were made'o ascertain compliance with the governing document.
Portions of the following activities were witnessed by the inspectors:
Cover plate removal Removal of crawler-transporters Placement of RPV on cribbing in vertical position Cleaning and inspection of RPY flange prior to lift Reactor pressure vessel lift, Lowering RPV into containment building through the biological shield wall.
The above mentioned lifting activities were done using the Lampson Twin Tr ansi-Lifts.
The sequence of events called for holding the reactor vessel over bolts set in the base plate, vessel rotation to the required positioning, lower-ing RPV over the bolts and setting the vessel onto the base plate.
. Inspection prior to lifting the vessel from the shipping skirt revealed that certain of the flange inner circle of bolt holes were partially obstructed by bottom head insulation support bars.
The inspector observed that the RPY was lowered onto cribbing on the base plate to permit clearing the obstructed bolt holes.
Procedure LUR WP-08 was revised to permit the change in procedural sequence.
FDDR number
<Gl-36, was written by General Electric Company representatives to permit remov-ing the obstructing portions of the insu/ation support The inspector's observations included verification that the vessel was set plumb within established limits and a portion of the feeler gaoge measurements of the spacing between the vessel flange and the base plate.
Results of the measurements were used to determine the necessity for placing shims between the flange and base plate in certain locations.
The inspector found that the vessel placement activities were carri ed out in accordance with approved procedures and that required procedural changes were properly made.
halo items of noncompliance were identified.
