5.0 PROGRAM DEVELOPMENT AND COMPONENT SELECTION The scope of the Prairie Island IST Program includes pumps and valves which are required to perform a specific function in shutting down the reactor to the hot shutdown condition or in mitigating the consequences of an accident. (Prairie Island's USAR defines safe shutdown as hot shutdown.) The pressure relief devices within the scope of the IST Program are those for protecting systems or portions of systems which perform a required function in shutting down the reactor. Systems included are those identified in the USAR that are ASME classified for IST purposes. The classification of systems was performed using Regulatory Guide 1.26 Revision 2, " Quality Group Classification and Standards" as guidance.
Code boundaries are defined on the ASME Code Classification Drawings (NH39800 series).

Additionally, a review against the Prairie Island Single Failure Criteria was performed to assure all required functions to protect against an active or passive single failure is appropriately tested. The definition of single failure criteria as used here is:
Fluid and electrical systems are considered to be designed against an assumed single failure if neither (1) a single failure of any active component (assuming passive components function properly), nor (2) a single failure of any passive component (assuming active components function properly) results in a loss of the capability of the system to perform its nuclear safety function.
As stated, this definition indicates that only a single active or a passive failure need be considered and not both. Further guidance on the single failure criterion can be found in the Engineering Manual Section 2.4.3.
6.0 SYSTEM TECHNICAL POSITIONS 6.1 Code Bqundary Valves ,
Prairie Island was designed in accordance with ANSI B31.1-1967. At the time there was no specific code classification for components. The original design utilized " Design Class 1" as the design criteria for safety related systems. With the classification of systems to comply with ASME Section XI requirements boundary valves were identified. In the case where the valves are the boundary between Class 1 and Class 2 piping the valves are in the program because they serve a specific safety related function in the closed direction. In the case where the boundary valve is between Class 2 and Class 3 piping the valves serve no specific safety function in the closed direction and the valves are not tested in the program. Specific application of this position is in the component cooling and cooling water systems adjacent to the containment penetrations. Reference Safety Evaluations 322 and 365. i O

Pane 13 _ . ,
6.2 Shutdown Safety Assessment as it Relates to Refueling Deferrals it has been recognized that there is risk associated with doing maintenance and testing with the Unit at cold shutdown. To maintain the defense in depth concept when a Unit ,
is at cold shutdown Prairie Island has developed a Planned Outage Management Philosophy which encompasses the plant's Shutdown Safety Assessment Process.
The process assures there is always sufficient support equipment to mitigate the consequences of events and prevent events from occurring. For these shutdown safety reasons, many components that are thought to be testable at cold shutdown are deferred to refueling shutdown. The scope of the shutdown safety assessment is developed from the NUMARC 91--06 document. The charging system has the most components that fall into this category.
6.3 Post Accident Sampling System (PASS) Valves Valves in the post accident sampling system are not covered by the IST Program. .The function to open to obtain a sample is not a specific safety related function in shutting down the reactor. Containment isolation valves that are also PASS valves are in the program and tested in the closed direction only, which is their safety function in shutting O down the reactor. .
6.4 Cooling Water Header Branch Connection Valves Branch connections valves on the cooling water header that are less than 3.0" in the screenhouse and less than 4.0" in the plant are excluded from the program. Safety ,
Evaluation 348 shows that the plant can withstand a line break in these areas and still maintain the required cooling water flows. The isolation valves in these smaller lines i are primarily the boundary between safety related and non-safety related portions of the cooling water system. Piping and branch connections larger than the above criteria are all safety related in design. In accordance with plant design criteria the size of any postulated passive failure is on the order of 50 gpm and the cooling water system is again designed to withstand such malfunctions without the need for isolation.
6.5 ' Pressure Isolation Valves Deferrals have been written for testing of the pressure isolation valves at a frequency other than quarterly. (See the individual Deferrals) It is Prairie Island's position that the pressure isolation valves and the injection check valves are additionally tested in series to assure the isolation function is being satisfied on a daily basis via the Reactor Coolant System Leakage Rate Test SP1001aa. This daily testing further substantiates the Deferrals.

j 6.6 Inservice Purge System and Containment Purge. I l
During normal operation the inservice purge system and containment purge system are out of service and the valves are not tested as part of the IST Program. Technical Specifications allow use of the inservice purge system during operation if the valves are first tested. The requirements of OM-10 paragraph 4.3.2.5 for valves in systems out of service will be followed. I l
6.7 Manual Valves l
Manual valves that are required to be repositioned in the accident mitigation or for maintaining safe shutdown are in the IST Program. Manual valves in safety related systems that are not required to be repositioned are considered maintenance valves unless they have remote position indication in which case they are treated as passive valves.
G.8 Charging Pumo Classification The charging pumps at Prairie Island are positive displacement low volume pumps.
The pumps are not utilized in any accident analysis and are not relied upon to mitigate g
the consequences of an accident. The charging pumps are therefore, not in the program. Since the charging pumps do not perform a safety function there is no need to have the boric acid transfer pumps in the program either. The charging pumps and boric acid transfer pumps are considered necessary only to maintain the pressure l I
boundary and are not tested in accordance with the IST Program.
Piping and valves associated with the above pumps (with the exception of those l discussed in the next paragraph) are only relied upon to maintain a system pressure boundary. None of the valves are required to reposition to perform and therefore are l
not in the IST Program.
Check valves VC-8-14, VC-8-15, VC-2-1, VC-2-2, and VS-13-2 and manual valve VC-15-40 are required to maintain a closed system outside of containment following an accident to capture any potential leakage past the charging and seal injection check valves. Reference Safety Evaluation 251 for more detailed discussion on this subject.
6.9 Full Stroke _Exetelsing of Check Valves The flow utilized in the Surveillance Procedures for full stroke exercising of check l valves to the open position SHALL be:
6.9.1 The design accident flow for the check valve plus margin to allow for instrument O
uncertainty, or

ASME SECTION XIINSERVICE TESTING H10.1 C - H' h Sectioni ,
IMPLEMENTING PROGRAM REV: 3 Paae 15 6.9.2 A flow that is sufficient to open the check valve and is periodically verified by non-intrusive testing. Other supporting parameters, such as pump speed or discharge pressure, as is the case with the AFW pumps, should be used to substantiate the opening of the check valve; or 6.9.3 A known single flow path such that the full flow is going through the check valve, such as with the SI pump or the AF pump recirc line check valves in the open direction. In this case the pump parameters should also be verified to assure the check valves open; or 6.9.4 Use of an unknown flow with the valve position verified by non-intrusive testing.
Gauges used for full flow testing of check valves should be a standard industrial grade ,
gauge and SHALL be calibrated on a frequency of 5 years or less.
6.10 Classification of Valves That Could Leak Back to the RWST Offsite dose analyses have been performed for a hypothetical RHR pump seal failure O postulated at 50 gpm, taking no credit for the Auxiliary Building Special Ventilation System. The analysis shows that 10 CFR100 limits are not exceeded with this postulated leak. This analysis bounds any expected leakage past check valves and :
other valves that could potentially leak back to the RWST and the valves are therefore not classified as Category "A" valves with specific leakage acceptance requirements.
The valves are periodically tested in the closed direction as required by OM-10 for Category "B" valves. The methods for testing the valves c!osed will detect leakage significantly lower than that stated above.
6.11 Coranonents not in the Program Later Determined to be Required in the Program Upon further review of the IST Program scope it may be determined that a component that is not presently in the program may be required to be in the program. If this arises, NRC G.L. 91-18 provides guidance for incorporating the component into the program and guidance for the timeliness of testing. ,
1 6.12 Position Verification and Classification of Valves Valves are classified as either passive or active as required by the Code with the plant being at power operation and the valves in their normal power operation position.
Valves used as support for maintenance of operating parameters that are infrequently operated, (i.e. accumulator drain valves or accumulator nitrogen supply valves) are O classified as passive since their period of use during the operating cycle is minimal and when operated they are under direct administrative control. These valves do undergo the position verification testing as required by the Code.

7.0 OM-6 PUMP TESTING IMPLEfLENTATION lt is not intended for this section to stand alone without NOTE *, needt referen e the Code. It is intended to show how Prairie Island is implementing OM-6. Work this section with Appendix J and K Unit 1 and Unit 2 Pump Tables.
7.1 Definitions 7.1.1 Reference Values: One or more values of test parameters measured or determined when the pump is known to be operating acceptably.
7.1.2 System Resistance: The hydraulic resistance to flow in a system.
7.1.3 Reference Curve: A pump curve developed from a family of reference values when the pump is know to be operating acceptably.
7.2 Testin93_ ash The entire inservice testing program for pumps is predicated on the basis that the hydraulic and mechanical condition of a pump relative to a previous condition can be determined by attempting to duplicate by test a set of reference values. Deviations detected are symptoms of changes and, depending upon the degree of deviation, indicate need for further tests or corrective action.
7.3 Ies1100 Requitements 7.3.1 Each pump in the program is required to be operated quarterly at its reference flow point, or against its reference flow curve if relief has been obtained, while monitoring and recording pump differential pressure and vibration levels. The pump SHALL have been operating for a minimum of 2 minutes prior to taking data to allow a period of stabilization (reference NUREG-1482 Section 5.8).
7.3.2 The data taken above SHALL be compared against the values for the pump l when it was in a known good operating condition as required in OM-6.
7.3.3 Pumps falling within the alert range SHALL be evaluated for operability within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> and the frequency of testing SHALL be doubled until the cause is determined and rectified.

7.4 Reference Curve Method The Code does not allow the use of reference curves for testing of pumps. Where the use of a reference curve is necessary relief from the Code is necessary. The following l guidance is provided for Reference Curve development (where relief has been obtained) and SHALL be used:
7.4.1 Pump reference curves are to be prepared or manufacturer's curves validated when the pumps are known to be operating acceptably.
7.4.2 When measuring the reference points for plotting or validating the curve, instruments at least as accurate as the Code, OMa 1988 Part 6 Table 1, SHALL be used.
7.4.3 Each curve will be constructed with a minimum of five points.
7.4.4 The reference curve will be constructed using only those points beyond the " flat' portion (Iow flow rate) or the pump curves in a range which includes or is as close a practicable to design basis flow rates.
7.4.5 Acceptance criteria for the pumps will be established such as to not conflict with the operability criteria for flow rate and differential pressure in the Technical Specifications of the USAR. Instrument uncertainty is to be included in assuring the reference curve is above the minimum allowable operational limits.
7.4.6 If vibration levels vary significantly over the range of pumping conditions a method will be prepared to assign appropriate vibration acceptance criteria for regions of the pump curve.

7.4.7 When the refererice curve may have been affected by repair, replacement or routine service, a new reference curve will be plotted or the previous curve revalidated by conducting an inservice test.
NUREG/CP-0123 " Proceedings of the Second NRC/ASME NOTE *.. Symposium on Pump and Valve Testing" has some recommendations on curve fitting methods to minimize the deviation between the curve fit and the actual data.
7.5 Iesting Methods for IST Program Pumoa 7.5.1 Safety Inlection Pumps _
The safety injection pumps are tested quarterly with a non-instrumented mini flow line. Each refueling oute.ge the SI pumps are full flow tested in the accident mode with the exception that the mini-flow line is isolated to allow measurement of full flow, which meets the requirements of GL 89-04 position 9.
Acceptance criteria specified in OM-6 are not as restrictive as the accident analysis flow and pressure when taking instrument accuracies into account and have therefore been adjusted to a tighter acceptance band. The acceptance criteria are specified in Surveillance Procedure 1092A[2092A].
To assure the recirculation line is a fixed resistance the orifice in the line will be periodically inspected.
7.5.2 Residual Heat Removal Pumpa The RHR pumps are tested using a fixed mini-flow line. Instrumentation for flow measurement is installed yet, cannot be accurately read to meet the Code requirements due to hydraulic fluctuations at the flow orifice. Hydraulic snubbers in the upstream and downstream pressure sensing lines do not significantly reduce the fluctuation to an acceptable value. The hydraulic instability is believed to be caused from pump suction and discharge recirculation and minor cavitation. The flow in the mini-flow line has been reviewed in accordance with NRC Bulletin 88--04 and found to be acceptable by the pump manufacturer.
l Other compounding causes of the hydraulic instability is the designed location of the flow orifice, which is not located free from any local flow obstructions. Even though instrumentation on the recirculation meets the Code requirements it cannot be read with sufficient accuracy for repeatable Code testing and is of little value to trending the pump parameters. The meter is not being removed g because it is used as a "go-no-go" gauge for monitoring flow for pump protection.

7.5.3 Component Cooling Water Pumps [
The component cooling water pumps are tested quarterly in accordance with the Code with relief obtained for the use of reference curves. Reference curves were established as indicated above. See Relief Request No.12.
7.5.4 Coolina Water Pumos The cooling water pumps are tested quarterly in accordance with the Code with relief obtained for the use of reference curves. Reference curves were established as indicated above. See Relief Request No. 5. ;
T O Less than full flow is measured due to the pumps supplying the diesel engine cooling and pump lubrication. See Relief Request No.15 and 16. Monitoring of the resistance of the cooling and lubrication lines will be performed periodically to assure the resistance is unchanged.
Suction pressure for the cooling water pumps is obtained by using intake bay level as authorized by NUREG-1482 paragraph 5.5.3. Its accuracy is within the .
2 percent required by the Code and the conversion methodology is described in the surveillance procedure for the cooling water pumps.
The diesel driven pumps are tested as above at a speed set to the reference speed.
The diesel driven cooling water pump configuration does not specifically fit the ,
classic vertical line shaft pump definition and therefore, the locations for taking vibration measurements as specified in the Code cannot be met. _In the case of the diesel driven cooling water pumps the pump is coupled to the diesel engine via a right angle drive gear. To meet the intent of the Code the vibration location i specified as the upper motor bearing housing is interpreted as being the bearing i on the driven gear, which is closer to the base of the gear, which will reflect in !
better indication on pump degradation. Three orthogonal vibration measurements are taken at the base of the gear which are representative of the driven gear vibration.

8.1.5 Stroke Time Reference Value: Baseline valve timing value obtained when the valve is known to be operating acceptably. The value SHALL be obtained by tests that are performed under conditions that are as near as practicable to those expected during subsequent inservice testing. Reference values are obtained from (1) Original preoperational testing,(2) Post-maintenance testing, or (3) The initial performance of a surveillance test for valves being added to the program.
8.2 Valve Cateaorles Valves in the program are classified into one or more of the categories listed below in order to establish the required inservice testing.
8.2.1 O Category A - valves for which seat leakage is limited to a specific maximum amount in the closed position for fulfillment of its design basis function.
8.2.2 Category 8 - valves for which seat leakage in the closed position is inconsequential for fulfillment of its design basis function.
8.2.3 Category C - valves which are self-actuating in response to some system characteristic, such as pressure (relief valves) or flow direction (check valves) for fulfillment of it design basis function.
8.2.4 Category D - valves which are actuated by an energy source capable of only one operation, such as rupture disks or explosively actuated valves.

l Page 22 8.3 Testing Categories and Frequency Valves in the program are required to be tested in accordance with the requirements of OM-10 paragraph 4. The testing and frequencies listed below are a summary of the Code requirements.
8.3.1 Valve Position Verification: All valves in the program, including manual valves, that have remote position indication SHALL be observed locally at least once every two years to verify the valve operation is accurately indicated. Where practice.ble, this local observation should be supplemented by other indication such as flow to verify obturator position. The implementation of remote position indication is not specifically listed in the valve tables but is covered in the surveillance procedures typically on a yearly or refueling basis.
8.3.2 Valve Exercising Test: OM-10 requires active Category A and B valves to be full stroke exercised to the position required to fulfillits function (s) quarterly. Where it is not practicable to perform this testing quarterly, alternate frequencies are permissible provided the reason for impracticality is documented and the alternate testing is implemented. See Section 8.4 of this document and Section 4.2 of OM-10 for more information.
8.3.3 Power Operated Valve Stroke Timing: Stroke timing is to be performed on all active Category A and B valves in the program. The stroke time SHALL be measured from the start of the control switch position change until dualindication of the position indication clears indicating the valve has stopped travel. For valves not meeting these requirements a consistent method for repeatable stroke timing SHALL be established and the method documented in the surveillance procedure for the component. The stroke time of all power operated valves SHALL be measured to at least the nearst second. Reference stroke times are to be established for each valve when it is known in be operating acceptably.
8.3.4 Fail Safe Valve Testing: Valves with fail safe actuators (control valves) SHALL be tested by observing the operation of the actuator upon the loss of valve actuating power. This is accomplished on valves with pilot solenoid valves each quarter during the normal valve exercising due to de-energizing the solenoid valve. Valves with positioners are tested by venting off the air supply. The plant has no fail safe motor operated valves.

8.3.5 Valve Seat Leakage Rate Test: Seat leakage tests are required to be performed on Catergory A valves at least once every two years. Containment isolation valves are tested in accordance with the Local Leakage Rate Testing Program which meets the requirements of 10CFR50 Appendix J. Pressure isolation valves are tested during the refueling outage RCS pressure test with the acceptance specified by the Technical Specifications.
8.3.6 Safety and Relief Valve Test: Safety and relief valves are tested in accordance with OM-1 and are addressed in Section 9.0 of this document and by Operations Manual Section D44.
8.3.7 Exercising Tests for Check Valves: OM-10 requires active Catergory C check valves to be full stroke exercised to the position required to fulfill its function (s) quarterly with methods for testing allowing verification of obturator position.
Where it is not practicable to perform this testing quarterly, alternate frequencies are permissible provided the reason for impracticality is documented and the alternate testing is implemented. See Section 8.4 of this document and Section 4.3 of OM-10 for more information.
8.3.8 Rupture Disk Tests: Rupture disks are tested in accordance with OM-1 and are addressed in Section 9.0 of this document. It should be noted that the only rupture disks in the program are those on the TDAFWP exhaust line.
Application of the testing requirements to each individual salve is specified in the Valve Tables in Appendix A and B [E and F). The IST Design dasis Document, Appendix D,
[ Appendix Hj specifies the safety function of the valves which in turn establishes the Code required testing. Actualimplementation of the valve testing requirement is performed via the Surveillance Program, and the procedure numbers are also referenced in the Valve Tables.
8.4 Deferral of Testing to Cold or Refueling Shutdown It is required by the Code to document the testing frequency and the basis for the impracticality of testing valves at the required quarterly frequency. Documents entitled
'IST Program Deferrals" have been prepared to establish Prairie Island's position for deferring testing to either cold shutdown or refueling shutdown. Deferrals were established using the following criteria:
8.4.1 Cycling of the valve could cause a potential trip. i 8.4.2 Cycling of the valve could cause system or component damage.
8.4.3 Cycling of the valve could cause excessive personnel hazard. I l

- NUMBER:
l,J ASME SECTION XI INSERVICE TESTING H10.1 g EI IMPLEMENTING PROGRAM REV: 3 W Sectionb ,
Page 24 8.4.4 Cycling of the valve could cause an undue risk in plant safety or over-burdensome valve manipulations are required to achieve the results.
8.4.5 Cycling of a valve and potential failure could cause a complete system failure.
8.4.6 Cycling of a valve would cause a perturbation on other active systems; such as a reactivity change in the RCS from a system other than the makeup control sytem.
Deferrais address the impracticality of testing the valves in both the open an closed directions when testing is required to be performed in both directions at a frequency other than quarterly. Entry into LCO's that are longer than 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> is not considered adquate basis for deferral of the testing.
Deferrals for Unit 1 and 2 are found in Appendix C and G, respectively.
Valve full stroke exercising deferred to cold shutdown SHALL be exercised during each cold shutdown unless the last full stroke exercise was performed within the previous 3 months. Valve exercising during cold shutdown SHALL commence within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of achieving cold shutdown and continue until all testing is complete or the g
plant is ready to return to power. All valve testing required to be performed during a refueling outage SHALL be completed prior to returning the plant to operation. See OM-10 Section 4.2.1.2. (f), (g) and (h) and 4.3.2.2. (f), (g) and (h) for specific details on extended cold shutdown outages.
In the case of valves that are deferred to a refueling outage; for extended cold shutdown periods the practicability of testing the valves at cold shutdown should be reviewed by the IST Program Engineer and any additional testing performed.
8.5 Methods of Valve Testing This section documents Prairie Island's use of "other positive means" of verifying obturator position for valve sting to assure compliance with the Code. i 8.5.1 Check valves that provide a support function to a pump (mini-flow check valves) in open direction tyically do not have any flow indication. Assurance that the obturator of these valves travel to the open position is verified by monitoring pump parameters during the running of the pump test and assuring the pump operates as required with no signs of malfuction, such as heatup or elevated vibration.

8.5.2 Testing of check valve obturator travel to the closed position is performed by pressurizing the downstream side of the check valve and observing other system parameters to assure the check valve obturator pontion is in fact closed.
Examples would be a build up of pressure downstream of the valve,' no build up !
of pressure upstream of the valve, or monitoring the shaft of the pump directly i upstream of the check valve to assure it is not spinning in reverse. +
8.5.3 Check valves on the steam supply to the auxiliary feedwater pumps were initially r tested using non-intrusive test methods to assure the obturator travel to the open position. Subsequent testing has monitored pump parameters to assure the valves travel to the full open position. Periodic retesting using non-intrusive testing is also used to reverify the testing methods.
8.5.4 Accumulator check valves are tested by measuring a level change within the accumulator and assuring the rate of change is sufficient to exercise the obturator to the full open position. This method of testing is periodically verified to be acceptacle by performing a non-intrusive test in parallel to confirm the testing.
8.5.5 Position verification on the head vent solenoid valves cannot be performed by ,
locally verifying the valve stem since it is fully enclosed and cannot be seen without valve disascembly. Position is verified by flushing water through the valve and assuring that the valve can isolate the stream of water when the remote position indication shows the valve is closed.
8.6 Valve Stroke Timing 8.6.1 Maximum allowable valve stroke time is based on a limiting value either established by the accident analysis or required in the original purchase specification for the valve, whichever is limiting.
8.6.2 At Prairie Island, valves are typically timed by using the remote position l Indicating lights. Most valves have dual light indica; ion when in the mid-position. l To time the opening or closing of these valves, a stopwatch is started as soon as the control switch is changed and stopped when the dual position clears. Valves not having remote position indication are timed locally from a predetermined ;
initiation event untilit is observed that the valve stem has stopped moving.

Final Review At the end of the procedure insert the following:
Verify test data does not exceed published action levels. IE required THEN take action per Section 1.0.
14.0 INSTRUMENTS AND INSTRUMENT ACCURACY .
Accuracy as it applies to the Code refers to the percent of the full scale for individual analog instruments, percent of total loop accuracy for a combination of instruments, or over the calibrated range for digital instruments. For instrument loops, accuracy is determined by the root sum of squares method using the accuracy of the individualinstruments. No "non-random" or " bias" error, such as orifice plate tolerances, wear, or temperature corrections are included. Inaccuracies of the calibrating instruments are also not included.
Calibration frequency is acceptable provided the instrument is on a regular schedule. The frequency is not specified in the Code, but it is performed at frequencies typical for the type of instrumentation based on past performance.
The individualiristrument accuracies are: !
Pressure gauges +/- 1% Tachometers +/- 1%
Flow elements +/- 1% Transmitters +/- 1/2%
SQ root extractors +/- 1/2%
Local flow indicator +/- 1/2%
Control Board Indicater +/- 2%
Emergency Response Computer Indication +/ .2%
Vibration Instruments +/- 5%
The resultant instrument loop accuracies are:
Cooling Water Flow +/-1.2% >
Cooling Water Bay Level +/- 1.9%
SI Suction Pressure +/- 1.4%
Si Flow +/- 0.7%
Component Cooling Flow +/- 1.25%
Auxiliary Feedwater Flow +/- 0.7%
Safeguards Chilied Water Flow +/- 1.12%
q All required instrumentation is specified in the equipment Surveillance Procedure as well as V the required vibration pickup points. Additionally, the vibration pickup points are also marked on the pumps.

Justification: It is not practicable to full stroke or part stroke exercise AF-15-1 open quarterly because this testing would require injecting cold auxiliary feedwater into the steam generators when the Unit is on line. Injection of cold auxiliary feedwater causes a thermal shock to the steam generator nozzle which needlessly reduces the nozzle design life. Furthermore, injection of cold water will cause a reactivity addition, making it necessary to compensate for the change. It is not practicable to test AF-15-1 obturator travel to the closed position quarterly or at cold shutdown. Closed valve position cannot be verified because there is no valve position indication. The proposed testing methods either render the entire AFW system inoperable since it is necessary to isolate AFW to both steam generators and requires setup of external pressure sources and test equipment which could delay plant startup. During cold shutdown periods the AFW pumps are frequently used for filling the steam generators for appropriate chemistry control. Additionally, aligning an external pressure source would require both AFW pumps to taken out of service to protect the individuals performing the test from an unplanned auto-start of the AFW pumps.

H10.1 Rw. 3 Page77 IST PROGRAM DEFERRAL Applicable Valve:CC-61-1 System:CC - Function: Valve is open to provide a component cooling flowpath to the reactor coolant pump. Valve closes upon a ; postulated single failure of a component cooling pump start i to prevent bypassing RCP component cooling flow to the idle component cooling loop. Justification It is not practicable to test CC-61-1 obturator travel to the closed position quarterly or at cold ; shutdown. Closed valve position cannot be verified because there is no valve position indication. The proposed testing method renders component cooling to the reactor coolant pumps out of service requiring stopping of the reactor coolant pump, or if not stopped, potentially damaging the pump. During cold shutdown reactor coolant pumps are often used as a dedicated decay heat removal path with an operable steam generator in the shutdown safety assessment. ) O Furthermore, the testing would require non-intrusive valve position monitoring or the use of an external pressure-source which could delay the plant startup. i It is not practicable full stroke exercise or partial stroke exercise the valve to the open position quarterly or at cold shutdown. Open valve position cannot be verified because there is no valve position indication. Installed instrumentation which could be used to determine position indication is inconclusive for testing since it measures flow in a common header upstream of the valve and the flow ! through parallel flow paths could not be determined. Exercising the upstream MOV to vary the flow may potentially cause flow perturbations to the RCP thermal barrier flow instrument potentially causing a spurious isolation of component cooling to the RCPs. During cold shutdown reactor coolant pumps are often used as a dedicated decay heat i removal path with an operable steam generator in the shutdown safety assessment. Testing would require removing the reactor coolant pumps from service. The only feasible testing is with the use of non-intrusive techniques which could delay the plant start up. During power operation component cooling flow to the reactor coolant pumps is maintained at all times so there is assurance that this valve or the same valve on the opposite train is open to provide the required flow. Historically, there have been no operational or maintenance

It is not practicable full stroke exercise or partial stroke exercise the valve to the open position quarterly.or at cold shutdown. Open valve position cannot be verified because there is no valve position indication. Installed instrumentation which could be used to determine position ! indication is inconclusive for testing since it measures flow in a common header upstream of the valve and the flow through parallel flow paths could not be determined. Exercising the upstream MOV to vary the flow may potentially ; cause flow perturbations to the RCP thermal barrier flow instrument potentially causing a spurious isolation of component cooling to the RCPs. During cold shutdown reactor coolant pumps are often used as a dedicated decay heat removal path with an operable steam generator in the shutdown safety assessment. Testing would require removing the reactor coolant pumps from service. The only feasible testing is with the use of non-intrusive techniques which could delay the plant start up. During power operation component cooling flow to the reactor coolant pumps is maintained at all times so there is assurance that this valve or the same valve on the opposite train is open to provide the required flow.

Justification: It is not practicable to test CC-3-3 obturator travel to the closed position quarterly or at cold shutdown. Closed valvo position cannot be verified because there is no valve position indication. First, testing would require the removal of RCS letdown and excess letdown from service, to place the high pressure on the downstream side of the valve, leaving no flowpath out of the RCS which would in turn fill the pressurizer and trip the unit on high pressurizer level. Second, testing would place a large flow perturbation on the component cooling system, potentially starving flow to the reactor coolant pumps and causing pump damage. And finally, testing would require removing one of the residual heat exchangers from service during this transient condition.

Valve is closed to prevent back-flow through a non-operating SI pump. Justification: It is not practicable to full stroke exercise SI-10-1 open quarterly or at cold shutdown. Full stroke exercising of SI-10-1 requires injecting water into the RCS. RCS pressure is above SI pump shutoff head when at power. Injection into the RCS at cold shutdown requires removal of the reactor head to satisfy technical specifications. It is not practicable to partial stroke exercise SI-10-1 open quarterly since this would require opening the only containment isolation valve which is normally closed in the SI test line. Use of this flowpath at power has not been hydraulically analyzed for SI flow, such that a single failure of a SI pump may not allow full SI flow to the RCS until the manual isolation valve is reclosed. Additionally, W use of this flowpath quarterly would increase the amount of time the SI pump is operated on mini-flow potentially damaging the pump. It is not practicable to partial stroke exercise SI-10-1 open at cold shutdown due to the additional time required to operate the pump on mini-flow recirculation which may cause equipment damage and because the shutdown safety assessment uses the SI pump as a makeup path upon loss of shutdown cooling. It is not practicable to test the obturator travel of SI 1 to the closed position quarterly or at cold shutdown. Use -" an external pressure source is required. If a high e source is used there is a potential of

Secondly, the accident a.._.ysis assumes the piping is filled with borated water so a borated water source would be needed or a method to replenish the boric acid would be required. Boric acid source are not readily available which would be capable of refilling the SI discharge piping.

Valve is closed to mitigate a postulated passive single failure of the downstream motor operated valve between the RHR and CS systems. NORMAL FUNCTION (S): Valve is closed to prevent backflow to caustic standpipe from refueling water storage tank. I TEST TYPE: It is not possible to fully stroke exercise CA- 11-1 to the full open position since the check valve is oversized for its service to minimize the pressure drop across the valve. The valve is partial stroke exercised open each quarter in accordance with OM-10 paragraph 4.3.2.2(a) and SP1354. Obturator travel to the closed position is tested each quarter in accordance with OM-10 paragraph 4.3.2.2(a) and SP1354. Since full stroke exercising to the open position cannot be performed the valve is disassembled each refueling outage in accordance with OM-10 paragraph
- 4. 3. 2.4 (c) . Inspection results for the 1994 refueling outage will be used as a basis to extend the inspection interval to a 10 year interval and a Relief Request No.17 from the Code provides the justification for extending the interval. See Deferral CA1.
COMMENTS: Accident flow through the valve has a volume of approximately 71 gpm. Calculations show that it takes approximately 230 gpm to get the valve full open. The flow through the valve during partial stroke exercising open is estimated to be less that 10 gpm.

Valve is closed during long term recirculation upon a failure of the downstream motor operated valve. NORMAL FUNCTION (S): The valve normally prevents back flow from the RHR system to the RWST during surveillance testing of the RHR pumps. TEST TYPE: Exercise full open each refueling per SP1092B and OM-10 paragraph 4.3.2.1 and 4.3.2.2(e). Test obturator travel to the closed position quarterly per SP1089 and OM-10 paragraph 4.3.2.2(a). l COMMENTS: See Deferral SI18 and SI19. Testing in the closed direction relies on pressurizing the RHR pump suction above the head of the RWST. This pressurization is typically accomplished during the running of the RHR pump due to pump heat. During testing when the RHR system is already warm work orders may be written to test the system with an outside pressure source. The flow required to verify the valve is full open is 1800 gpm based upon the minimum low head injection flow required ( by Technical Specification 4.5.

Valve is a relief path for thermal expansion of the trapped fluid in the regenerative heat exchanger. Minimal relief capacity is required and the flow acceptance is therefore set at 3 gpm. The present method of testing the obturator travel to the closed position is to use radiography since there are no upstream vents for the valve. Non-intrusive test methods have given indeterminate results because of the small valve size. A modification is being initiated to install a vent path upstream of the valve.

Valves in Code Class 1,2, and 3 systems have been categorized in accordance with ASME/ ANSI OMa-10,1988.
- 2. LEGEND TEST TYPE: TEST FREQUENCY:
E = exercise Q = quarterly Sy = 5 year SP = relief valve R = refueling 10y = 10 years LT = leak test CS - Cold shutdown PV = position verificatien 2y = 2 year
- 3. Position verification is performed on a!I non-Category C valves at least once every two years.
- 4. Inservice valve testing at cold shutdown is defined as: Testing is required if not done in the previous 90 days. Valve testing should commence not later than 48 hours after shutdown and continue until complete or plant is ready to retum to power.
Completion of all valve testing is not a prerequisite to retum to power. Any testing not completed at one cold shutdown should be performed during the subsequent cold shutdowns to meet the code specified testing frequency.
- 5. The column titled " Valve Function" describes the valve function as defined by the ASME Code (active or passive). In addition, the valvo position required for accident mitigation is included. For example, an active valve that is required to open for accident mitigation is listed as "act-open". For an active valve that is required to open and close for accident mitigation is "act-both".
