Catawba Units 1 and 2 Specific Relief Request Item Number:

Pump:

CN-SRP-CA-01 CA Pump IA, CA Pump 1B, CA Pump 2A, CA Pump 2B, Test Requirement:

Basis for Relief:

Oma-1988, Part 6, Section 4.6.1.2.a requires that the full scale range of the instrument shall be three times the reference value or less.

The installed process instrumentation for the CA pumps suction pressure measurement is as follows:

Local 0-160 psig (0.5% error) 0-160 psig (0.5% error)

Control Room 0-90 psig (1.12% error) 0-90 psig (1.12% error)

Test Alternative:

10/31/02 Rev. 26 The typical range of values for the suction pressure of the CA pumps during testing is 33-38 psig; therefore, the local process instrumentation on CA Pumps IA/2A and IB/2B does not meet the three times criteria.

The accuracy of the process instrumentation (0.5%) is well below the requirements specified in Oma-1988 Part 6, Table I for pressure instrumentation accuracy (2.0%).

The actual reading error at test pressure due to the process instrumentation accuracy is 2.42% (0.5%

• 160/33). If a 0-90 psig test instrument is used (which meets the three times criteria) and it has an accuracy of 2.0%, then the reading error due to instrument accuracy would be 5.45% (2%

• 90/33). When the requirements of Oma-1988 Part 6, Section 4.6.1.2.a and Table I are combined, the actual instrument error introduced to the test is less than the code allowable (2.42% vs. 5.45%). Using the process instrument for suction pressure data does not degrade the quality of the test, and meets the intent of the instrumentation requirements of the code.

The installed process instrumentation at both the control room and locally at the CA pumps can be used to measure CA pump suction pressure for CA Pump IA, CA Pump IB, CA Pump 2A, and CA Pump 2B tests.

10/31/02 Rev. 26 CN-GRV-01 All safety and relief valves tested under ambient conditions using a test medium at ambient conditions.

All applicable Provide over-pressure protection to associated systems.

OM-1, 1987 Sections 8.1.2.8 and 8.1.3.7, Time Between Valve Openings; A minimum of 10 min. shall elapse between successive openings.

This is a generic request for relief for safety and relief valves in compressible fluid service (other than steam) and liquid service applications, tested under ambient conditions using a test medium at ambient conditions.

For these valves, the requirement for verifying temperature stability (by waiting 10 min. between successive openings) is inappropriate and of no value. There is negligible affect on valve setpoint due to minor temperature deviations that might occur at these ambient conditions.

The net result of having to wait 10 minutes between successive openings is an increase in manpower and time to perform the tests and an increase in radiation exposure when located in radiation areas, without a commensurate increase in test accuracy.

Note:

This issue has been identified by the ASME Code Committees along with safety and relief valve industry experts and is reflected in a change made to the 1995 version of the code (Appendix I). In addition, NUREG -1482, 4.3.9 (6) STATES "Thermal equilibrium need not be verified for liquid service valves tested at ambient temperature using a test medium (at ambient) temperature."

For safety and relief valves tested under ambient conditions using test medium at ambient conditions, the 10 min. hold requirement between successive openings will be deleted.

This is a generic request for relief for all safety and relief valves.

The 1995 version of the code, Appendix I has adopted a 5 minute hold time for steam, compressible fluid, and water service applications rather than the 10 minute hold time. This change was based on actual test data that revealed insignificant effect on valve setpoint by reducing the hold time between successive openings to 5 minutes.

For safety and relief valves tested at other than ambient conditions, a 5 minute hold time will be used between successive valve openings.

All applicable Provide over-pressure protection to associated systems.

OM-1, 1987 Sections 8.1.2.4, 8.1.3.4, Temperature Stability; the temperature of the valve body shall be known and stabilized before commencing set pressure testing.

This is a generic request for relief for safety and relief valves tested under ambient conditions using a test medium at ambient conditions.

For these valves, the requirement for verifying temperature stability (by ensuring no change in measured temperature of more than 10°F in 30 minutes) is inappropriate and needlessly adds time to the test activity. Since the valves will be tested at ambient conditions, no temperature differential exists and the valves would already be considered stable per the test requirement above.

There is negligible affect on valve setpoint associated with any minor temperature deviations at these ambient conditions.

Note:

This issue has been identified by the ASME Code Committees along with safety and relief valve industry experts and is reflected in a change made to the 1995 version of the code, Appendix I, ("Verification of thermal equilibrium is not required for valves which are tested at ambient temperature using a test medium at ambient temperature").

For safety and relief valves tested under ambient conditions using test medium at ambient conditions, the Temperature Stability requirements of OM-1, 1987 Sections 8.1.2.4 and 8.1.3.4 will be replaced by the Thermal Equilibrium requirements in the 1995 edition of the code.

10/31/02 Rev. 26 In NUREG 1482, Guidelines for Inservice Testing at Nuclear Power Plants, the Commission approved Owners adopting later Editions or portions thereof of the ASME Code provided those Editions or portions are approved per 10 CFR 50.55a (f)(4)(iv) and provided documentation of implementation is provided in the IST program and all conditions of Commission approval are satisfied. For this relief, the licensee is requesting to partially implement the 1995 Code Edition (ISTC, OMa-1996) to selected IST program check valves.

As an alternative to the testing or examination requirements of ISTC-35 10, ISTC-3520, ISTC-3540, and ISTC-522 1, the Owner may establish a condition monitoring program. The purpose of this program is both to improve check valve performance and to optimize testing, examination, and preventive maintenance activities in order to maintain the continued acceptable performance of a select group of check valves. The Owner may implement this program on a valve or a group of similar valves. The program shall be implemented in accordance with Appendix II, Check Valve Condition Monitoring Program.

If the condition monitoring program for a valve or valve group is discontinued, them the requirements of ISTC-5221 shall apply.

These valves are normally closed and open to provide starting air to the diesel engine.

Exercise each valve (full stroke) to the position required to fulfill its function and stroke every three months.

Valves are arranged in pairs (one solenoid and one check) for each two lines to each starting air bank. The diesel can start with one line from either bank. Valves do not provide indication of position, therefore a full stroke for each valve cannot be verified.

Relief was requested based on the "skid mounted" criteria and verification of acceptable starting performance from each bank.

This alternate testing has been approved via Request for Relief granted by the NRC dated 11/18/99.

Each diesel is started once monthly to prove operability. Also, during each cold shutdown, each bank of each diesel is isolated and acceptable diesel starting performance is verified. This confirms that at least one pair of valves of each bank performs acceptably and redundancy is provided.

10/31/02 Rev. 26 Valves NI0144A are motor operated valves on the NI Pump B miniflow line. The valves are open during the injection mode when the NI Pumps are operating.

During the recirculation mode, when the NI Pumps are taking suction from the containment sump (via the ND System), the valves are closed to isolate the miniflow line. Closure of the valves prevents the possibility of introducing reactor coolant water into the FWST and diversion of flow from the NC System. The valves are also interlocked with valves ND0028A & N10136B such that they can not be opened unless valves ND0028A and NI0136B are closed.

2 These valves must automatically close to isolate containment upon receipt of a Pressurizer Low Level signal, if either valve I(2)NVOOO1A or 1(2)NVO002A closes, upon receipt of a Phase A Containment Isolation Signal (ST), or on a concurrent failure of the PD pump and both centrifugal charging pumps.

These valves are cross-interlocked with valves 1(2)NVOOOIA and 1(2)NVO002A such that they will automatically close if either 1(2)NVOOOIA or I(2)NVO002A is not in the "Open" position. These valves can be operated from the Auxiliary Shutdown Panel, and cannot be opened unless valves 1(2)NVOOO1A and 1(2)NVO002A are both open.

Measure Full Stroke Time/Failed to Safe Position - Quarterly Stroke time and observe fail-safe operation every three (3) months.

Letdown header relief valve I(2)NVO014 has experienced lifting and subsequent seat leakage as a result of pressure transients during orifice swaps for stroke time testing of valves I(2)NVO01OA, l(2)NVOOIIA, and 1(2)NVO013A.

Leakage past 1(2)NVO014 is considered Reactor Coolant (NC) system leakage. This leakage directly impacts Technical Specification.

Based on the above, testing of these valves is impractical and non conservative during power operation.

Valves l(2)NVOOIOA, 1(2)NVOOIIA, and I(2)NVO013 will be stroke time tested and fail-safe operation verified during cold shutdown.
