  • Designates those personnel in attendance at the exit meeting on February 26, 1985 . Preventive Maintenance Program The preventive maintenance program for the extended construction delay is described in WMC-051 entitled, "Preservation of Assets Preventive Maintenance Program," Revision 3 of November 25, 1986. The inspector reviewed the changes made.to this program since the previously reviewed Revision 2. The major changes are to Sections 5.5 ard 6.3. Section was addei to clarify the use of equipment shrouds; Section establist a tracking system addressing concerns observed during the quarterly inspection activit The only significant changes to the Appendices to WMC-051 were to Appendix A. Appendix A contains the minim"m preventive maintenance requirements for preservation of equipment during the extended construction delay period. The inspector utilized vendor's recommendations and EPRI NP-5106, "Plant Layup and Equipaent Preservation Sourcebook," as reference sources for evaluating the acceptability of the changes. The following observations we.c noted and discussed with the licensee: For certain equipment, such as pumps, air compressors, and motors',

the periodic requirement to respike the oil reser/oirs with VPI (Vapor Phase Inhibitor) was changed from.12 months to 24 month This change applied to the two types of corrosion inhibitors used at WNP-3, Cortec - used to protect the internals of hermetically sealed

components, and Vaportec - used to protect sumps and other equipment containing lubricating oil Justification for use of Cortec every

'

two years is addressed in licensee Interoffice Memorandum (IOM) N PT-3-CCC-86-21 from the Plant Technical group to Plant Maintenance, dated February 7,1986. Based on past experience obtained from periodic inspections for corrosion, this IOM states that components protected with Cortec and sealed with caps, tape, plaotic., plywood or similar materials shall be inspected.on a two (2) year interval with reapplication of Cortec following each inspectio The requirement for the use o+ Vaportec on a 24-month interval comes from an engineering evaluation and recommendations from Mobil Oi IOM No. MD-3-JAK-83-7 states that "...if the system or component is closed or sealed ana is not in operation, one application of Vaportec will last indefinitely (3 to 5 years)." The licensee took the conservative approach by extending the VPI application to a two year requirement. Further extension of the inspectionApplication interval will be considered ty the licensee after completion of the first two year inspection cycl Concurrence on the use of both Cortec and Vaportec was obtained from the plant maintenance manager, the plant technical manager and the resident engineer. The inspector is satisfied that sufficient technical justification is documented to support these change B. The preventive maintenance program, as described in WMC-051, Appendix A, does not contain provisions to ensure that rotating machinery, such as horizontal pump motors, are periodically rotated to assure the bearings are lubricate EPRI NP-5106 recommends shaft rotation every two or three months. Discussion with licensee maintenance personne'l revealed that shaft rotation is being performed on a three-month schedule; this was supported by the preventive maintenance schedule and records of completed wor !

Shaft rotation is addressed in Procedure CSP-9-02, Revision 1 of February 19, 1982, entitled, "Stored Equipment Maintenance and Preservation." Tie licensee informed the inspector that they have considered eliminating the requirement for shaft rotation based on ;

IOM No. ESS-03-86-37 of October 14, 1986. Basically, this IOM says !

that if you have a good corrosion control program, then periodic shaft rotation is not require ,

The maintenance group did not agree l with this justification, so shaft rotation is still being performe At the exit meeting, the inspector emphasized the importarce of I assuring that shaft rotations remain a requirement for preventive maintenance of rotating machinery until such justification is agreed upon by the NR C. The Supply System and EBASCO had previously developed their own procedures for implementing the preservation program described in l WMC-05 These procedures have recently been consolidated and l reissued as Combined Site Procedures or CSP The following CSPs i were reviewed by the inspector for significant program changes: '

Preventive Maintenance Records The computerized Scheduled Maintenance System (SMS) lists approximately 4,500 item. , their dates of last performed maintenance, and .the due dates for the next scheduled maintenance. The inspector randomly selected 15 safety-related items from this list for examination with due dates between December 1987 and February 198 The records in the QA vault were reviewed by the inspector to confirm that the scheduled preventive maintenance was performed for the following items: SI-MTR-2A - High Pressure Safety Injection Pump Shaft Rotation (1000 HP motor).

All the'above items, with one exception, had the required preventive maintenance task oerformed as scheduled. The one exception was for the reapplication of Cortec for item.3-AF-PP-18; the justification for extending the scheduled was provided (refer to Section 2.B of this report).

No violations or deviations were id3ntifie . Corrosion Monitoring Program The Structural Material Corrosion Monitoring Program is described.in WMC-051, Appendix B (Revision 1 of February 21, 1986). .Briefly, corrosion coupons are placed on test racks located in the field and in the buildings to provide information on structural material changes due to the environ:nent through'the period of construction delay. The inspector observed the corrosion coupons at the following test locations:

outside adjae.ent to the WNP-3 cooling. tower, inside at the 481 foot level of the Reactor Building, and outside at the 390 foot level north tank

, far The corrosion coupons were as described in WMC-051, Appendix B, regarding materials, size, and identificatio The corrosion Log Book is maintained offsite by the Responsible Engineer in Richland, Washington and, therefore, was not available for revie However, the inspector did review QA Surveillance Report No. WNP-3-87-004 conducted on March 3,1987, to verify the corrosion monitoring program's compliance with applicable 10 CFR 50, Appendix 8, criteria. This surveillance included a review of the corrosion "Log Book" and the "WNP-3 Photo Log." Examples of significant deficiencies reported were:

traceability of tut coupons to vendor mill test reports not entered into corrosion log book, test coupons not properly identified, the Photo Log was not being maintained at the site, and retrieved coupons were not preserved and retained at the PSF Corrosion Laboratory. A total of ten (10) deficiencies were identified during a one-day surveillance performec'

by the PQAE and the site principal Nuclear Engineer. This surveillance report supports the previous NRC concerns that the corrosion monitoring program appears to be functioning outside the applicable criteria of 10 CFR 50, Appendix This was expressed in NRC Report No. 50-508/87-0 The corrective actions have or will be closed by June 1988, the date ;

EBASCO has committed to the licensee to have completed revising WMC-051 ;

in accordance with Surveillance Report No. WNP-3-87-004. The tracking !

system utilized to followup on these deficiencies is discussed in Section j 6.A of this report. As a result of the QA surveillance and the i subsequent revision to WMC-051, the resulting corrosion monitoring l program should be in accordance with 10 CFR 50, Appendix !

No violations or deviations were identifie . Licensee Action on Previously Identified NRC Inspection FindinSS (Closed) Followup Item No. 50-508/87-02-01, "Status of Tracking System for Discrepancies Identified During Corrosion Inspections" Discrepancies identified during corrosion inspections are now entered in the Startup Tracking System (STS). The STS is a computerized EBASCO system for tracking, monitoring, and assigning responsibility for resolution of open deficient items for-a startup syste The WNP-3 Resident Engineer added Site Action Item List

.

(SAIL) items to the STS which includes cor osion inspection deficiencies. The corrosion engineer completed an audit of post quarterly reports, back to 1983, and entered any unresolved items into the STS. All items entered into the STS remain in the computer indefinitel The inspector reviewed a computer printout of items entered into the STS and is satisfied with this method of tracking deficient item This item is close (Closed) Followup Item No. 50-508/87-02-02, "Assess Impact of New Work Load on Maintenance Staff" This item addresses outstanding Maintenance Work Requests (MWRs)

. with the concern that with EBASCO turning over warehouse activities to the existing supply system staff, the outstanding MWRs might get beyond contro That is, it could have a negative impact on the timeliness of completing backlogs and future identified maintenance and preventive maintenance action MWR computer runs are provided on a weekly basis to appropriate discipline supervisors and management for their awareness of MWRs awaiting to be worked. The inspector reviewed the January 1988 plant maintenance report which listed the total open MWRs; subsequent discussions with the Maintenance Support Leader on the breakdown of open MWRs revealed the following:

On January 31, 1988, there were 325 open NWRs of which 223 were startup MWRs; these are not scheduled to be done until startup, l

, This leaves 102 MWRs with 16 MWRs awaiting reproval, parts, '

The inspector met with licensee management representatives denoted in i paragraph 1 on February 26, 1988. The scope of the inspection and the l inspector's findings, as noted in this report, were discussed.
