Instrumentation Maintenance
The instrumentation maintenance program was examined for conformance with
regulatory requirements, Technical Specifications, and licensee
commitments.
The inspector selected a number of preventive maintenance activities that
4
were in progress in connection with the reactor protection system and the
engineered safety features system. The inspector then proceeded to
review the procedures for the licensee's corrective and preventive
maintenance program. The inspector's review established that the
licensee has satisfactory procedures to accomplish preventive
maintenance. The following items were observed in the reviewed
procedures:
a.
Administrative approvals for removing and restoring an. item to
service, with specific attention to system lineup and verification
prior to its return to service.
b.
Provisions to require the latest approved drawings and instructions
are used.
c.
Provisions for returning the item maintained and the affected system
to the original configuration following maintenance, and verifying
that the configuration is correct.
d.
Provisions for operational readiness testing of item maintained and
affected system following maintenance.
e.
Provisions for the control of housekeeping during the maintenance
effort.
f.
Provisions for cleaning safety-related systems /cotcponents during
maintenance.
t
.

.
.
g.
Provisions for obtaining approval from operations when affected
systems are removed from service and when systems are ready to be
restored to normal service.
The inspector's review of. corrective and preventive maintenance
procedures found one procedural deficiency.
This procedural deficiency was found during review of PICT-10-1, Reactor
Protection System, and was that the test equipment used was not recorded
on the data sheet, namely a stop watch and a Fluke Digital multi meter
used for the functional reactor trip breaker test. The Instrumentation
and Control Supervisor initiated a change to PICT-10-1 data sheet to
include the test equipment used in the PICT.
The inspector observed work in progress with Instrumentation and Control
(I&C) personnel. The inspector observed the following items during the
work process:
,
a,
that proper operational personnel had been notified and clearance
issued
b.
appropriate maintenance work orders had been issued and approved
c.
that the latest approved procedures, drawings, and instructions were
being used
d.
that qualified test equipment and tools were being used
e.
that adequate identification of jumpers and lifted leads were
maintained
f.
that proper restoration of barriers and covers were accomplished
g.
that required system lineups had been accomplished and verified
prior to functional testing
h.
that adequate functional testing was performed prior to returning
the equipment to operations for system restoration.
The inspector's review of the maintenance activities in progress
established that the licensee had satisfactory procedures and personnel
to perform the desired maintenance activity. The inspector found another
procedural deficiency during review of PICT-12-1 Seismic Monitoring
Triaxial Time-History Recording. This deficiency was in Paragraph 9.0,
" Acceptance Criteria", in which the acceptable requirements of the
graphic recordings should all meet the requirements of step 7.2.21.
Step 7.2.21 was incorrectly referenced and the correct reference should
have been Step 7.2.22.
The Instrumentation and Control (I&C) supervisor
initiated a procedural change to PICT-12-1 to correctly specify
step 7.2.22.
The inspector reviewed records of completed maintenance activities of the
I&C department. The inspector observed the following items during the
record review:
.
i

.
required administrative approvals were obtained prior to initiating
a.
the work
b.
the acceptance criteria were met
c.
functional testing, adjustments, and calibrations, as necessary,
were completed prior to returning the equipment to operations
d.
qualified personnel performed the activity
e.
corrective, and preventive maintenance records were assembled,
stored, and retrievable as part of the maintenance history
f.
records, plans, drawings, and instructions which were affected have
been updated.
The inspector discovered during the record review that during various
performances of PICT-11-1 Nuclear Instrumentation, Power Range Setpoint
Test, that the step 7.2.3, Power Range High Voltage, was not recorded in
the PICT-11-1, data sheets. The dates of performance and Power Range
Channels were July 9, 1985 (Channel No. 44), October 7, 1984 (Channel
No. 41), June 20, 1984 (Channel No. 42), and May 12, 1984
(Channel No. 43). This appears to be a violation of Technical Specification Section 6.8.1, which requires that written procedures shall
be established, implemented and maintained covering surveillance and test
activities of safety-related equipment (50-344/85-36-01). The inspector
also discovered that test equipment type data was not fully recorded
'
during the performances of the following PICTs:
(1) PICT 2-1 (Reactor Coolant Flow, Protection Set I) dated January 2,
1985; September 3, 1985.
(2) PICT 2-2, dated October 3, 1983; January 2, 1985; September 3, 1985
(3) PICT 2-3, dated October 3, 1983; January 2, 1985; September 3, 1985
(4) PICT 3-1, (Steam Flow-Feedwater Flow, Steam Line Pressure and
Turbine First Stage Pressure), dated September 4, 1985
(5) PICT 3-2, dated July 15, 1985; September 5, 1985
(6) PICT 4-1, (Pressurizer Level Trip Setpoint Test-Protection Set 1)
dated August 28, 1985; September 9, 1985
(7) PICT 4-2, dated August 28, 1985; September 9, 1985
(8) PICT 4-3, dated August 28, 1985;' September 9, 1985
These various PICTs required that the equipment type and tag number of
the test instrument used be recorded on the various PICTs data sheets.
The inspector found numerous data sheets in which only a digital volt
meter was recorded, and not the ramp generator used as specified in the
test equipment section of the PICT. This is also considered to be an
-

.
apparent violation of Technical Specification Section 6.8.1
(50-344/85-36-01).
3.
Electrical Maintenance
The electrical maintenance program was examined for conformance with
regulatory requirements, Technical Specifications, and licensee
commitments. The inspector selected a number of preventive maintenance
activities that were in progress in connection with the safety-related AC
and DC control power systems, and normal power distribution systems. The
inspector.then proceeded to review the procedures for the licensee's
corrective and preventive maintenance electrical program. The
inspector's review established that the licensee has satisfactory
procedures to accomplish electrical preventive maintenance. The
electrical maintenance procedures had similar provisions as the I&C
procedures discussed in the above paragraph 2.
The only procedural
deficiency discovered was in Maintenance Procedure MP-1-5 Reactor Trip
and Bypass Breakers, which did not have the test equipment used listed in
Attachments 2 or 3.
This item will be followed up on during a future
inspection (85-36-02).
The inspector reviewed work in progress and completed electrical
maintenance records and found that the licensee's electrical maintenance
program to be satisfactory. The inspector observed the following items
during the record review:
a.
required administrative approvals were obtained before initiating
the work
b.
the acceptance criteria were met
c.
referenced procedures were' approved and appeared adequate for the
activity
d.
functional testing, adjustments, and calibrations, as necessary were
completed before returning the equipment to operations
e.
qualified personnel performed the activity
f.
corrective and preventive maintenance records were assembled,
stored, and readily retrievable as part of the maintenance history
file.
The licensee's corrective maintenance and preventative maintenance
activities relative to electrical components and systems were conducted
in accordance wit'i the licensee approved procedures and instructions.
The electrical maintenance program appears to meet the requirements of
regulatory guides, industry codes, and the Technical Specifications.
No deviations or violations were identified in this area of inspection.

Follow-up on Previous Inspection Findings
(Follow-up Item 85-23-01; Closed) I&C New Computer Maintenance System
The inspector interviewed the I&C supervisor concerning the new computer
maintenance system presently being used to track maintenance. The I&C
supervisor informed the inspector that the new system was performing
excellently and had no errors for the two months in use.
In addition,
the old computer tracking system was being deleted.
LOOP 1136 is being
closed by the Quality Assurance Department. This item is considered
closed.

Exit Interview
The inspector met with the licensee representatives denoted in
paragraph 1 on October 25, 1985, and summarized the scope and findings of
the inspection activities.
