1 PLANT STATUS
During this inspection period, the plant was operating at power.
2 $URVEILLANCE TESTlHG AND CALIBRA110N COUROL PROGRAMS (61700 AND 61725)
The purpose of this inspection was to assess the implementation of the
licensee's surveillance testing and calibration control programs.
2.1 Discussion
2.1.1
Surveillance Program
The inspectors reviewed the licensee's surveillance arogram for scheduling and
performing tests, calibrations, and checks required )y the Technical
Specifications.
The administrative requirements and responsibilities of the
surveillance program were detailed in the Cooper Nuclear Station Operations
Manual, Procedure 0.26, " Surveillance Program," Revision 8.
The procedure
assigned the responsibility for scheduling surveillance activities and
maintaining the status of surveillance tests to the surveillance coordinator.
The responsibility to coordinate with other shift activities and to authorize
the actual performance of the test was assigned to the control room shift
supervisor.
During the inspection, the inspectors witnessed three surveillance activities
required by Section 4 of the Technical Specifications.
The activities
witnessed were performed using the following surveillance procedures:
Procedure 6.2.2.5.7, "RHR Loops A and B Pump Low flow Switch Calibration
and Functional / Functional Test," Revision 17;
Procedure 6.2.2.1.4, "CS and RHR Pump Discharge Permissive Calibration
and functional / functional Test," Revision 17; and,
Procedure 6.3.18.3, " Service Water Surveillance Operation," Revision 27.
The personnel performing the surveillance activities were knowledgeable of the
procedure requirements and kept operations personnel informed of the
surveillance test status.
The surveillance procedures clearly identified the
Technical Specification requirements and acceptance criteria.
The inspectors
verified that the instrumentation / control technicians performing the test and
calibration activities were <;ualified and used calibrated instruments,
in addition, the inspectors selected and reviewed a number of surveillance
test records representing 14 different surveillance requirements of the
-.

Technical Specifications.
The surveillance testing related to the following
areas of the Technical Specifications:
Reactivity control and power p 9 ration,
Instrumentation.
Emergency core cooling system,
Containment system,
Electrical power system,
Fire protection system, and.
Inservice testing program.
The surveillence records confirmed that the required surveillance activities
were performed satisfactorily and at the specified frequency.
The inspectors
also verified that the surveillance test procedures clearly specified the
Technic 9 Specification surveillance requirements and that the surveillance
test results were reviewed by the Shift svervisor.
The inspectors reviewed the four most recent license amendments, of which the
latest was Amendment No. 156, dated December 22, 1992.
This review verified
that changes made to the surveillance program were incorporated into the
surveillance procedures and master surveillance schedule.
2.1.2 Calibration Control Program
The inspectors reviewed the licensee's calibration control program for
scheduling and performing calibration of safety-related process
instrumentation installed in the plant that were not specifically controlled
by Technical Specifications or the temporary measuring and test equipment
program. The programmatic requirements of the process instrumentation
calibration control program were detailed in the Cooper Nuclear Station
Operations Manual, Procedure 0.38, " Process Instrumentaticn Program,"
Revision 2.
The inspectors reviewed the calibration-records for selected process
instrumentation installed in the plant and used to provide data for the
l
inservice testing witnessed during the inspection. The inspectors verified
l
that the process instrumentation used for these surveillance activities were
l
included in the calibration program and that the calibration was current.

2.2 Conclusions
The licensee has developed administrative procedures which clearly define
responsibilities for scheduling and performing surveillance testing and
calibration activities.
Operations personnel are effectively scheduling,
performing, and updating the surveillance testing and calibration control
programs.

3.1 10.1ned}_. Inspection followun Item 298/9102-01:
Perform Snecial Test to
Determine Seryls.e Walar Purro Room Temoeratutes _durina Symmer Months upon
L933 of Heatino
__f.411 tion. and Air Condiligning
The inspectors verified snat a special test had been conducted to measure the
heat-up of the service water pump room with two pumps rur,ning and without
heating, ventilation, and air canditioning.
Th resulting service water pump
room temperatures were evaluated as acceptable by the Nuclear Engineering
Department. The licensee also incorporated the results of the service water
pump room temperature test into Revision X of the Updated Safety Analysis
Report.
3.2
(Closed) Insoection followun Item 298/9102-02 L,1pnpuct a Water Hammer
Analysis of the Service Water System dur_ino a loss of Offsite Power,
The inspectors verified that the water hammer analysis of the service water
system had been completed by the Nuclear Engineering Department. The results
of the analysis indicated that the service water system would remain operable
following a loss of power and the restart of two pumps after the diesel
generators have energized the essential buses.
