MAINTENANCE PROGRAM IMPLEMENTATION (MODULE 62700)
An inspection was conducted to determine whether the licensee's maintenance-program .
is being implemented in accordance with requirements, to determine 'the effectiveness
of the maintenance program on important plant equipment, and to determine the
ability of the maintenance staff to conduct an. effective maintenance program.
2.1
Review of Records Associated with Maintenance Activities
- The licensee's procedure for the control of work on any Structure, system, or
compc>nent at the site was reviewed as were a number of completed maintenance work
packages. Documents which were reviewed are listed in Attachment 2.
-
In general, the work packages ~ere found to have been prepared in accordance with
the licensee's administrative requirements.
Work packages were noted to include procedures to be used, appropriate maintenance
. directives, drawings, and other reference material needed to perform the work. Shift
supervisors permission is required prior to beginning any work activity. Quality
assurance inspections were performed when required. Site personnel qualifications are
maintained; when contractors were used their qualifications were documented. -Parts
and materials which were used were identified.
-
The licensee's work control procedure states: Work Orders (WO) and the information
generated to document the work on the structures, systems, or component are
designated to support component history and the Station Performance Monitoring
Program. Also, the corrective action taken to prevent reoccurrence of the *problem
and a description of the cause of the failure is required to .be documented .
4.
The inspector noted that these procedural requirements were sometimes wen'
documented on some WO's while on others the documentation .was less complete.
- This was discussed with the licensee. . The 'licensee indicated that this had been
recognized and that to improve documentation in these areas the WO form was in the
process of being modified.*. The modified form has an expanded activity description
portion, as well as an expanded description of the work performed section. The
description of work performed section will specifically require the identification of the
as found condition, the repair actions taken and the failure cause. The inspector was
provided with a draft of the new WO form. The licensee indicated that, when the
new form is issued, personnel training will be conducted which will emphasize the
importance of complete documentation.
The licensee's self-identification of the documentation weakness, as well as the
initiation of corrective action, is considered to be a positive initiative.
An additional existing effort to improve work packages is the inclusion of a planned
package feedback sheet in each WO. This sheet provides for work package
improvement suggestions, as well as documentation by the planner as to the action
taken as a result of the suggestions. The conscientious use of these sheets should help
. improve work packages.
. It was noted that a detailed procedure has been prepared which provides instructions
. for required post maintenance testing (PMT} and operability testing. However, the
. WO form does not have a PMT block and PMT is frequently identified under the
activity description. For several of the completed work packages.which were
. reviewed, identification of the PMT which was performed was difficult. The
requirement for and* the documentation of PMT was discussed with the licensee. *The
licensee indicated that the identification and documentation of required PMT was
currently under review and that improvements were anticipated.
2.2
Review of Maintenance Procedures
Several maintenance procedures used in the performance of the maintenance tasks
were reviewed by the inspector. Procedures which have been prepared- in accordance
with the procedure upgrade project conform to the licensee's administrative
requirement for updated procedures. Step by step instructions are included as are
.
.
inspection hold points. Reference material and drawings are identified or provided,
and provisions for control 9f equipment are prov:ided. Notes and caution statements
are highlighted. The procedures appear to provide sufficient detail for the work to be
performed .

2.3
- Machinery History Records
- Machinery history *records in four maintenance packages for equipment which was*
. worked that were reviewed by the inspector were discussed with the appropriate
. system engineers. The equipment worked on consisted of the No. 11 Boric Acid
Transfer Pump, No. 12 Diesel Generator Starting Air Compressor Safety Relief
Valve, 1-B Di~sel Generator Slip Ring Refurbishment, and the 22MS 167 Main Steam
Stop Valve Inspection and Rework.
.
.
.
.
Jn. each instance, the responsible system engineer was very familiar with the
machinery history which is available on the computer. For t}lree of the four
components, the system engineer maintained his own fog which contained equipment
history. For the Diesel Generator Starting Air Compressor Safety Relief Valve, based
on maintenance findings, additional preventive maintenance is being considered. For
the main steam stop valve, the system engineer was familiar with the vendors *rebuild
report and had scheduled a meeting with the vendor to discuss the valve overhaul and
future overhaul requireinents. Engineering assistance was requested as required.
Overall good communications appear to exist between system engineers, maintenance
personnel and maintenance planners.
- The Reliability and Assessment Group is using machinery history records to provide
management with data associated with component failures. Several reports were
- provided to the inspector which indicate systems and components that have had
- * multiple corrective maintenance WO's prepared.
2.4
Preventive Maintenance Program
The licensee is in the process of making improvements to the preventive maintenance
(PM) program. PM's are being reviewed as a result of the reliability centered
maintenance reviews being conducted, certain PM reduction analyses are being
performed, work is*progressing on a predictive maintenance program, and an overall
review of the PM program is being conducted. Other activities associated with
maintenance program improvement include industry and in-house experience
. assessment, and system .maintenance effectiveness. An overdue PM report is prepared
and available to management. The overall result of the licensee's actions dealing with
PM's has been to significantly reduce overdue PM's. Also, to provide additional
- protection a new PM procedure requires that an evaluation be performed prior to the
deferral of any PM.

2.5
Control of Measuring and Test Equipment (M&TE)
- A review of records associated with several pieces of M&TE used to perform
. maintenance in the packages reviewed was performed.* This was a limited review
confined to only several pieces of equipment identified in Attachment 2. Step 5.1.4
. of procedure NC.NA-AP.ZZ-:-0022(Q), Rev. 1, Measurement and Test Equipment
(M&TE), and Tool Control, requires that, "M&TE shall be returned to the applicable
tool room immediately after completion of the WO or task for which it was signed
out, or after a period of seven days; whichever comes first." Although not part of the
M&TE procedure, ari M&TE tracking log is maintained at the issuing tool room.
This log for each piece of equipment, contains the issue and return date, requestors
identification, and usage data which includes the WO.the equipment was to be used
on .
. In the effort to follow up on several pieces of M&TE used on work activities reviewed
immediately upon examining the M&TE tracking log, it was obvious numerous pieces
of equipment had not been returned within a period of seven days. Ten pieces of
equipment were quickly identified which were out over seven days. One of these was
out past its calibration due date. A further review of four pieces of equipment showed
that two of the four were*not logged to the WO on which they were µsed. These two.
pieces: (1) SA-STR-1134, identified in a work package as being used during the
performance of WO 920406105; and (2) SA-SA-MMT 1520, identified as used during
the performance of WO 910730109, were never logged out to these WO's. This
appears to be contrary to the requirements of station procedures and is considered to
be a violation (50-272/92-11-01 and 50-311/92-11-01). No other.requirements
specified by the M&TE procedure were reviewed during this inspection.
3.0 *
CONCLUSION
The work control procedure adequately describes the preparation of work packages.*
.
.
Completed work packages were found to be prepared essentially in accordance with
procedural requirements. Deficiencies in documentation that appeared to exist had
been identified -by the licensee and corrective action was in the process of being *
. implemented. Improvements to the documentation to PMT is currently under review.
Adequate procedures for_ the performance of maintenance tasks are being provided ..
Machinery history records are being used to identify multiple maintenance on specific
components. Improvements to the PM program have been made and are continuing.
.
.
Deferred PMs are required to be evaluated. Progress has been made in reducing the
number of overdue PMs. *A lack of procedural adherence was identified relating to
the control of M&TE .
