ACTION ON PREVIOUS IDENTIFIED INSPECTION FINDINGS (92701)
'
(Closed)InspectorFollowupItem(298/8914-01):
Review of licensee's l
programmatic actions to verify improved control of vendor technical information.
This item related to an inspector's observation during the review of Design Change (DC)87-133, " Replacement of Overcurrent Relays 51/IFE and 51/ IGE on l
Vital Busses," that noted two different calculations had been performed by the licensee for determination of the overload protection setting of the replacement relays. The engineering person who performed the initial
calculation had made an erroneous assumption in the calculation. The licensee's personnel stated that the assumption was made because the vendor technical data provided with the relays by the manufacturer was inadequate.
A further review of this item was performed during NRC Inspection Report 50-298/89-28. At that time, it was ascertained that a revision to Procedure 3.4, " Station Modifications," was under review which included guidance to design engineers regarding review of vendor technical information.
.
.
,
e-3-The item was left open pending issuance of the revision to Procedure 3.4.
It was verified during this inspection that the revised procedure (containing guidance relative to review of vendor technical information prior to equipment installation)hadbeenissued,whichresolvesthismatter.

RECEIPT STORAGE. AND HANDLING OF EQUIPMENT AND MATERIALS (38702)
The purpose of this inspection was to ascertain whether the licensee is implementing a QA program that is in conformance with regulatory requirements, licensee commitments, and industry guides and standards relating to the control of the receipt, storage, and handling of safety-related equipment and materials.
3.1 Review of Program The CNS " Quality Assurance Program for Operation, Policy Document," Revision 5, dated June 7, 1989, Section 2.13, commits the licensee to follow the guidance prescribed by ANSI N45.2.2, " Packaging, Shipping, Receiving, Storage, and Handling of Items for Nuclear Power Plants." The administrative controls for the receipt, storage, and handling of equipment and materials were found to be delitiented in the following plant services procedures:
'
Warehouse Receiving, 1.5, Revision 10, dated November 21, 1989
Warehouse Marking and Tagging, 1.6, Revision 6, dated December 14, 1989
Warehouse Storage,1.7, Revision 6, dated January 18, 1990
Warehouse Issue and Return,1.8, Revision 8, dated September 9,1989 During the inspection, the inspector reviewed the above program procedures with respect to the requirements of ANSI N45.2.2 and 10 CFR Part 50, Appendix B, Criteria VII, VIII, XIII, and XV. Based on this comparative review, the inspector ascertained that the licensee's program procedures adequately addressed the regulatory requirements for the receipt, storage, and handling of equipment and materials.
No violations or deviations were identified in the review of program requirements.
,
I 3.2 Program Implementation
'
During the inspection, the inspector made a random selection of parts and assemblies that had been issued to the field and installed during the period 1988-1990 as indicated by completed maintenance work order requests (MWRs).
The items selected for review are listed in the Attachment to this inspection report.
During the review of the selected items, the inspector verified that procedural requirements were complied in regard to requisitioning, receipt inspection, i
storage and warehouse issue control. Essential attributes included in this i
review were as follows:
n
,
.
.
,
.
t
i Purchase orders contained description of codes, standards, tests, and
documentation requirements for materials, parts, or components.
Receipt inspection reports were adequately documented and described the
examinations performed.
Parts and components were properly identified and stored as governed by
the storage requirement for the item (Levels A through D)
Supplier was identified as a qualified vendor.
- Control of nonconforming items.
,
Identification and control of limited shelf-life items.
- j
.
,
Warehouse issue tickets recorded date of issue and parts or materials were
appropriately. identified and traceable to purchase order.
Based on this review, the ins)ector ascertained that the licensee was satisfactorily implementing tie program requirements for receipt, storage, and handling of equipment and materials, with no violations or deviations identified.
3.3 Review of Reactor Water Cleanup pipe Replacement Activities During the inspection, the inspector also made a walk-through tour of the newly constructed warehouse in which replacement reactor water cleanup pipe fabrication activities were being performed. The inspector reviewed the licensee's receipt inspection report dated March 10, 1990, for subassemblies that had been received from a vendor. Approximately 32 spool pieces were found to be dimensionally out-of-tolerance at the time-of receipt inspection.
In discussing the nonconforming spool pieces with the cognizant licensee representatives, the inspector was informed that the out-of-tolerance condition (i.e., warpage of prefabricated assemblies) was considered to be the result of improper spool piece support during the solution annealing heat treatment process. Also, since warpage was the only discrepancy identified, additional quality control inspections and engineering evaluations were being performed to determine rework requirements and usability of portions of the nonconforming spool pieces. The inspector observed that all nonconforming spool pieces were properly segregated and c1carly identified.
No violations or deviations were identified in the review of this activity.

EXIT INTERVIEW l
'
An exit interview was held on March 16, 1990, with those individuals denoted in paragraph 1 of this report. The inspector summarized the inspection scope and findings. The licensee did not identify as proprietary any information provided to or reviewed by the inspector.
