"Denotes those persons present at'he exit interview.
Plant Tour The inspector toured the Unit Nos.
1 and 2 reactor building, control struc-true, and primary containment.
He observed work in progress, quality control activities, and equipment storage.
An arc strike was noted on the reactor recirculation pipe spool VRR-B31-2.
The licensee issued a Field Inspection Report No. GE-7, dated June 26, 1980, which documented the removal, liquid penetrant testing, and ultrasonic thickness measurements made to correct the condition.
An overground co'ndition was noted on the toe of the lug weld attachments on pipe hanger HBB-ll0-H007.
Further measurements verified that the grind-ing did not exceed 1/32" as specified by the ASME III Code.
The quality control welding inspectors stated that they were aware of this practice and made measurements to confirm the'acceptability of this condition.
The inspector had no further questions concerning these matter Licensee Action on Construction Deficienc Re orts (Open) Anchor Darling Tilting Disc Check Valves (78-00-09):
The inspector reviewed 'the Bechtel "Final Report on Tilting Disc Check Valves Installed in Vertical Pipelines",
Management. Corrective Action Report No. 1-25, and PP5L letter PLA-280 which describe actions taken to correct the deficiency.
The check valves essentially fail to close by gravity when installed in a vertical position.
This was due to improper weight distribution about the center of,gravity on the tilting disc.
The problem does not affect all valves and therefore each valve must be tested prior to installing it in a vertical position.
The corrective actions consisted of the following:
(1)
Determine what Anchor Darling check valves were installed in the vertical position and effect repairs as needed.
(2)
Instruct the field to test all tilting disc check valves before install-ing them in the vertical position.
(3)
Revise the purchase specification to require that valves will close when installed in the vertical.
A note has been inserted on the Anchor Darling valve drawings advising that these valves have been modified to assure their closure in the verti-cal position..
This should preclude any design, modification, or mainte-nance changes being made without considering this aspect.
The field engineering group tested all valves installed in the vertical, valves scheduled to be installed in the vertical, and all spares in stor-age.
The valves that were tested were tagged as such; those that were not tested or indeterminate were 'tagged as not tested.
The inspector examined the computer log valve report which lists all valves and their intended location.
These were cross checked against the piping isometric drawings to determine the orientation of the valve.
Six titling disc check valves were identified as being installed in the vertical posi-tion.
These were examined to verify their orientation and that they were properly tagged.
Valves 1F012A and B were installed but tagged as not tested.
The cognizant field engineer stated that these valves were, in fact, returned to the manufacturer for repair and were tested.
The valves were apparently mismarked.
The inspector requested that the two valves be opened 'for retest due to the fact that they were tagged as not having been tested, there was no formal documentation available to support the fact they had been tested, and they were installed in the system.
The valves were opened and a visual inspection disclosed what appeared to be weld buildup on the disc stop of
each valve.
There was water and debris above the disc.
The disc of each valve was rotated open and released.
Valve 1F012B hesitated on 'several tries and ultimately failed to reseat by gravity.
It was verified that the specification M-221, Revision 12, Addendum 1, titled "Nuclear Service Valves 2 1/2 and larger", paragraph.4.10, was changed to require testing-of tilting disc check valves.
Based on the failure of valve 1F012B to.close, this item remains open pend-ing further -corrective actions by the licensee.
(Open) Limitorque Operator Stem Nuts (79-00-03):
A,review of the follow-ing documentation was performed to determine the scope and adequacy of the licensee's corrective actions:
Limitorque letter to Bechtel, dated September 17, 1978, describing the failure of valve manufacturers to properly stake stem lock nuts Management Corrective Action Report No. G-1 Final Report for Limitorque Motor Operator Valve Stem Lock Nut Staking, May 15, 1980 The proposed corrective actions are to:
(1)
Identify all valves requiring staking.
(2)
Request the jobsite stake all valves.
The foregoing activities will be verified at a subsequent inspection.

Licensee's Action on Previous Ins ection Findin s (Closed)
Unresolved Item (387/77-13-01 and 388/77-07-01):
Failure to main-tain PP&L guality Assurance Manuals current.
The licensee presented letters dated October 13, 1977; April 5, 1978; May 2, 1978; and August 3, 1978, which indicated that manual holders had been notified of their responsibility to mairitain their manuals.
It also documented the results of an audit which verified the g.A. manual status.
There are 60 copies of the manual.,cur-rently issued.
The inspecto~
examined 6 copies and verified that they were posted with the latest versions of the procedures.
This matter is considered closed.
(Open) Unresolved Item (378/77-13-02 and 388/77-07-02):
Failure to properly control project reference drawings.
The inspector randomly examined several
"stick files" of drawing in the licensee's corporate office.
Most drawings were marked "uncontrolled".
Discussions with personnel from the document control group disclosed that all drawings issued in the past year are marked "uncontrolled".
However, the department is currently engaged in
It an extensive program to enable it to accommodate the information to be received from the. plant jobsite.
New procedures are being written,,sys-tems developed, and new personnel trained.
The drawing "stick files" will
- all be update'd and completed in 60 days.
This item remains unresolved pending reinspection of the files. in 60 days.
5.
Unresolved Items Unresolved items are matters about which further information is required to det'ermine whether they are items of noncompliance, deviations, or acceptable.
Unresolved items are discussed in paragraph 4.
6.
Exit.Interview The inspector met with the members of the licensee's staff, denoted in paragraph one, on June 27, 1980, at the conclusion of the inspection.
He di'scussed the scope and findings of the inspection.
