Hugh C(.) Dance,' Shetion Chief Oate S'igned Division of Reactor Projects SUMMARY Scope:
This routine, announced inspection was conducted by the resident inspecters onsite, in the areas of monthly surfeillanct. observations, monthly maintenance observation, operational safety verification, engineered safety fr.atures system walkdown, and other areas.
Results: The licensee's maintenance and surveillance program appears to be strong and well controlled. Maintenance and surveillance technicians possess a good knowledge of equipment and procedures. The atta of fire protection has been plagued by personnel errors in timely identification of problems associated with inoperable fire detection equipment and/or inoperable fire barriers.
The licensee has in-creased management oversight and provided additional manpower and resources in this area in the past six months.
Correction of all existing problems in this area will require added management atten-tion.
Within the areas inspected, the following violation was identified:
Failure to establish compensatory fire watch, paragraph 4

Monthly Surveillance Obserntion (61726)
i
..
The inspectors observed surveillence activities of safety related systems
'
and components to ascertain that these activities were conducted in accordance with license requirements.
The inspectors observed portions of 23 selected surveillance tests and the major aspects of Emergency Diesel I
Generator "A", refueling inspection.
The inspectors also verified that
!
required administrative approvels were obtained prior to initiating the i
test, testing was accomplished by qualified personnel, required test
instrumentation was properly calibrated, data met TS requirements, test l
discrepancies were rectified, and thu systems were properly returned to
[
service.

Personnel performing surveillances had the applicable procedures in hand whiie performing tests.
No procedural errors were observed during the tests performances. The technicians appeared to be adequately trained and qualified to perform the surveillances.
The licensee's use of a buddy
system and train maintenance surveillances weeks is considered a strength.
!
This reduces the possibility of errors that could result in a plant trip.
No violations or deviations were identified.
3.
MonthlyMaintenanceObservation(62703)
The inspectors observed maintenance activities of safety related systems and components to ascertain that these activities were conducted in accordance with approved procedures TS and appropriate industry codes and standards.
The inspectors also determined that the procedures used were
!
adequate to control the activity, and that these activities were accom-plished by qualified personnel.
The inspectors independently verified that equipment was properly tested before being returned to service.
Additionally, the inspectors reviewed several outstanding job orders to l
determine that the licensee was giving priority to safety related maintenance and a backlog which might affect its performance was not developing on a given system.
The following specific maintenance activi-ties were observed:
l MWR. 21364006 Remove / replace gating and synchronizing amplifier on I
printed circuit board on inverter 5908 MWR 8700286 Replace filter on the air handling unit for the

The procedures were available at the work location and contained sufficient detail to allow the technicians to perform the required tasks.
The equipment
,
appeared to be maintained in a good state of repair.

Operational Safety Verification (71707)
a.
The inspectors toured the control room, reviewed plant logs, records and held discussions with plant staff personnel to verify that the plant was being operated safely and in conformance with applicable requirements.
Specific items inspected in the control room included:
adequacy of staffing and attentiveness of control room personnel TS and procedural adherence, operability of equipment and indicated control room status, control room logs, tagout books, operating orders, jumper / bypass controls, computer printouts and annunciators.
Tours of other plant areas were conducted to verify equipment operability, centrol of ignition sources and combustible materials, the condition of fire detection and extinguishing equip-ment, the control of maintenance and surveillance activities ir
.
progress, the implementation of radiation protective controls and the physical security plan.
Tours were conducted during normal and random off hour periods.
b.
The inspectors reviewed the licensee's 10 CFR 50.59 evaluation for plant 'coastdown" prior to shutdown for the fourth refueling cutage.
The analysis allowed RCS average temperature to drop appicyireteiy 5 l
degrees F while maintaining 100 percent reactor power during coast-l down.
The plant started coastdown on September 12, 1988. The plant j
was shutdown and entered Mode 3 on September 17, 1988.

c.
On September 6, 1988, at approximately 7:30 a.m. with the plant in Mode 1, fire protection personnel discovered that RIAr 6 was inoperable.
This was discovered during a review of the CRT printout by the fire protection supervisor. Upon discovery, compensatory fire watches were established as required by TS 3.3.3.7 for inoperable fire detection instrumentation.
A MWR was generated, the item was repaired and returned to service on September 6, 1988.
Further review of this item determined that this equipment, which provides fire detection instrumentation for eighteen spaces, had been inoperable since a lightning strike to the meteorological tower at 8:34 n.m. on August 30, 1988, a period of approximately 6 days.
The fire suppression portion of the system remained operable but the information and alarm function was inoperable.
Further review indicated that no alarm had been received but the CRT display and printout had consistently indicated an
"0" in the line for each attached space detector.
This indicates that the device is off line and inoperable.
However, the shif t fire protection officers reviewing this information had not been trained to identify the "0" as an off line inoperable condition.
Therefore, no compensatory action was taken.
The failure to establish compensatory fire watches within one hour af ter the equipment became inoperable is contrary to the requirements of TS 3.3.3.7 and is a violation, Failure to establish compensatory fire watch. 88-19-01. Although the licensee identified the violation and took prompt corrective action, proper training and guidance would have identified the problem.
The licensee is currently preparing a LER on this item.
S.
ESF System Walkdown (71710)
The inspectors verified the operability of an E3F system by performing a walkdcwn of the accessible portions of the RHR System.
The inspectors confirmed that the licensee's system lineup procedures matched plant drawings and the as-built configuration.
The inspectors looked for equipment ccnditions and items that might degrade performance (hangers and
!
supports were operable, housekeeping, etc.) and inspected the interiors
!
of electrical and instrumentation cab' nets for debris, loose material, l
jumpers, evidence of rodents, etc.
The inspectors verified that main flow path valves were in proper position, and power was available.
A portion of the walkdown was accomplished with the inspectors accompanying two auxiliary operators on a system walkdown, with the system in operation, to determine leakage per STP 150.004.
MWR's wete generated by operations to correct minor deficiencies identified during the system walkdown.
No violations or deviations were identified.
