l Instrument Air Ouality Verification l
Four test points in the Instrument Air system were sampled for water, oil, l
I and particulate by an industrial hygienist. The sample locations were selected to provide a representative sample of overall air system quality at points well downstream of the system's air dryers. Air samples from all four test points were found to be acceptable based on the requirements of air quality standard ISA-57.3, " Quality Standard for Instrument Air".
The air samples were not specifically tested for particle size.
Instead, a pre-weighed 5 micron filter was used to obtain a particulate sample.
The accumulated particulate concentration for a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period was measured and was found to be at the minimum detectable level. Vendors of safety-related valves were contacted to verify that their specifications do not impose stricter air quality requirements than the measured air quality.
A surveillance procedure will be implemented by July 1989 that will test system air quality semi-annually as discussed above.
The location of test points will be changed each time the test is performed. Test results will be used as a baseline for system air quality trending.
The instrument air system will be modified to provide for continuous monitoring of dew point at the discharge of the air dryers.
Air System Maintenance. Emercency Procedures and Traininn Maintenance Practices Preventive maintenance procedures related 20 the Instrument Air compressors and dryers were reviewed for content and frequency based on vendor technical manual recommendations, and were found to be adequate. A summary of this review is provided in Table 1.
Post maintenance testing of air-operated valves includes stroke-time testing, verification of proper stem direction travel, and position verification.
Abnormal Operating Procedures A review of the Instrument and Station Air system operating procedure has been completed with specific attention directed to the section addressing loss of instrument air. The following is a summary of the results of this review:
1 1
- 1. Indications of Loss of Instrument Air
' Alarms and automatic actions which occur during a loss of instrument air are adequately addressed in the current procedure revision.
I
- 2. Identification of Critical Components The procedure does not identify critical components operated by the Instrument Air system. However, fail positions of critical components are identified either by an engraved "F" on the associated lamp lens cover or by the position designated on the left side of the respective control panel switch.
- 3. Expected System and Plant Response The procedure lists expected system response, but it does not address integrated plant response or consequences related to an integrated plant response.
This area is adequately addressed in classroom and simulator training. No further revisions to the procedure are planned regarding plant response.
- 4. Manual Actions The procedure does not address actions to be taken if critical components do not fail in their intended position.
Tho procedure will be revised by July 1989 to include guidance with respect to failure modes of valves equipped with backup air accumulators.
- 5. Restoration Actions The procedure adequately addresses actions necessary to restore the system to normal operation following a loss of instrument air.
Trainine Classroom and simulator training for operators was reviewed with the plant training staff and found to be adequate.
The following training has been accomplished or scheduled.
- 1. Classroom Training
- a. License Requalification Training on Station and Instrument Air systems was performed early in 1987.
- b. Additional License Requalification Training is scheduled for 1989.
- c. INPO SOER 88-1 and IE Notice 87-28 were discussed in industry event lectures presented during the sixth requal cycle of 1988
- 2. Simulator Training
- a. SOER 88-1 was added to simulator scenario 116 in the "related event" section.
2
- b. A one-hour scenario followed the classroom instruction provided early in 1987.
- c. Additional simulator training is scheduled for 1989.
Review of System Desinn and Valve Failure Positions Air Supolv Original calculations for the sizing of the Instrument Air system, including compressors, air dryers, air receivers, and headers were reviewed and found to be adequate. Air-operated valve and instrument design loads, and system pre-operational tests were also reviewed.
Accumulator Tanks Safety-related valves that are equipped with backup air accumulator tanks are depicted with an asterisk in Table 2.
Accumulators associated with these valves were either vendor designed and specified in the valve's procurement specifications, or were of a generic design provided by the Architect Engineer. Applicable sections of the FSAR, USAR and mechanical performance specifications for these valves were reviewed to determine the functional requirements of the accumulators.
System pre-operational tests were also reviewed to verify accumulator performance was consistent with specifications. A summary of this review follows.
It should be noted that only the pressurizer power-operated relief valves and the containment vacuum breakers require an active source of instrument air to perform their design function.
- 1. Pressurizer Power-Operated Relief Valves Pressurizer PORV's were retrofitted with backup air accumulators in 1977 to improve the reliability of the Over Pressure Protection System (OPPS).
Each accumulator provides air for approximately 15 valve openings. The accumulators were originally procured with a specification to cycle the valves a minimum of 75 times without instrument air header pressure. A subsequent NRC Safety Evaluation Report (Reference 7) found the backup air supply to be acceptable.
- 2. Main Steam Isolation Valves MSIV's are equipped with accumulators supplied by the valve manufacturer which were designed to reduce the possibility that fluctuations in instrument air pressure could result in an inadvertent valve closure. The MSIV safety function is to close and remain closed. The accumulators help maintain the valves open during normal operation. No specific tests related to MSIV accumulator performance were found, and since the accumulators are provided in response to operational concerns and do not provide a safety function, no testing of the accumulators is deemed necessary.
- 3. Turbine Driven AFW Pump Steam Supply The turbine-driven AFW pumps were modified in 1981 to change the motor-operated steam supply isolation valve to an air-operated I
3 I
valve.
This valve is equipped with a backup accumulator designed for 2 valve operation cycles. Operational testing verified that
' the accumulator performance was consistent with specifications with its normal instrument air supply depressurized.
- 4. Containment Vacuum Breakers The Containment Vacuum Breakers consist of a fail-closed check valve in series with a fail-open butterfly isolation valve. Air is provided to the check valve for testing purposes only The isolation valve is equipped with a vendor-supplied accumulator designed for 2 valve operation cycles.
The common air supply to both valves is provided with a NAVC0 accumulator for which design base information could not be located. Testing of the valves with the normal instrument air supply isolated revealed that the accumulators were capable of providing air for 10 valve operating cycles. No reference in the valve procurement specifications or the USAR is made with respect to the functional requirements of a backup accumulator. However, the fail-open isolation valve is required to close on a containment isolation signal and the accumulators ensure that the valves will close in the event of a loss of air pressure.
- 5. Steam Generator Power Operated Relief Valves Each relief valve is equipped with a NAVCO accumulator for which design basis information could not be located.
Pre-operational testing did not include cycling of these valves with the instrument air supply depressurized. No reference to the functional requirements of the backup accumulators was found in the USAR or valve procurement specifications. However, the valve is equipped with a manual operator to provide for local operation should the normal and backup air supply fail.
Valve Failure Positions References 1 through 4 were used to compile a list of functional safety-related air-operated components for the purpose of failure position verification.
The components identified are listed in Table 2 along with their design failure position.
System pre operational test records were reviewed to identify any pre-operational tests performed on the components specified in Table 2.
The applicable pre-operational tests were then reviewed to determine the adequacy of the test and associated documentation.
Pre-operational tests which were found have to adequately verified the component failure position are listed in Table 2 with the associated component. As can be seen in Table 2, the failure position of several of the air-operated components could not be verified from the review of the pre-operational test records.
l The surveillance test program was also reviewed to identify surveillance procedures which could be shown to verify the failure position of the components listed in Table 2.
The individual surveillance test procedures 4
)
were reviewed along with the configuration of the components and their control circuitry. The surveillance tests which were found to adequately verify' component failure position are listed in Table 2 with the associated
)
component.
The surveillance procedures referenced include the response to safeguards signal test (SP 1083 and SP 2083), steam exclusion damper test (SP 1112), and valve exercise tests associated with Section XI testing.
Procedures could not be located which verified the failure position of the cooling water supply valves to the emergency diesel generators (CV-31505 and CV-31506).
This verification will be performed during the next monthly surveillance test of the emergency diesel generators.
