ATTACHMENT 4 PUMP AND VALVE LISTS FOR SECOND 10-YEAR INTERVAL
RISK-INFORMED IST RELIEF REQUEST FOR STP PUMP AND VALVE LISTS This attachment includes separate reports that provide the information normally submitted as the IST Plan document for the update requirement. The first report is titled IST Valve Groups and it lists all the IST scoped valves which are grouped by like components as described in the Risk Informed Inservice Testing Program Description. As a result of the 10-year update to the OMa-1988 Code, this list also includes the relief valves which are now scoped in the IST program based on the requirements of the OM-1 987 edition of Part 1.
The second report of this attachment is the listing of the testing requirements by group. This report shows the IST rank as determined by the Integrated Decision-making Process, the frequency tested under the previous edition of the Code, and the resulting risk informed test frequency. The table below provides a description of the frequency codes that are used in this report. Where applicable, a reference (i.e. CSJ
- 01) is added to indicate that the frequency is based on a cold shutdown or refueling outage justification.
IST FREQUENCY CODES a
Once per Quarter 30MO Every 30 months CS At Cold Shutdown 3YR Every 3 years 2Y Every 2 Years 54MO Every 54 months RF Every 18 months 5YR Every 5 years R
Every 18 months 6YR Every 6 years 6M Every 6 months 36MO Every 36 months App J Tested per Appendix J Option B The next report is a list of the ASME pumps included in the IST scope. This report shows the pumps divided in the groups for staggered testing. The pump safety function and the IST rank are displayed.
Again, the previous frequency and the resulting risk-informed test frequency are shown.
Finally, the last report provides the cases where STP is taking exception to the code requirements for IST High rank components. These activities cannot be performed during normal power operations.
The reasons for the testing exceptions and the proposed testing requirements are described. The report also includes the relief requests proposed by STP for situations where the ASME Code cannot be satisfied.

A. steam generator low water level, B. low feedwater flow signal from AMSAC, or C. SI initiation signal to allow 500 gpm (per Technical Specification 4.7.1.2.1) flow to Steam Generator 1(2)D.
NOTE: The ESF actuation signal allows the stop check valve to function normally through the self-actuating design of the check valve. Operation of the motor operator function is not required for the valve to fulfill its open safety function.
- 2. Close (remote manual) for Steam Generator 1(2)D isolation in response to SGTR, FWLB, and MSLB.
OMa 4.3.2.1 requires check valves to be exercised nominally every three (3) months. OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open or partially open position required to fulfill its safety function.
These valves can only be full-stroke open exercised by directing auxiliary feedwater flow into the steam generator. The initiation of auxiliary feedwater flow during power operation would result in unwanted thermal shock to the secondary portions of the steam generators. Additionally, the introduction of cold water to the steam generator would cause an unwanted power transient.
These valves will be full-stroke open exercised each cold shutdown unless the period of time since the previous full-stroke open exercise is less than three months. Auxiliary feedwater flow will be directed through the valve from its respective pump and into the steam generator. Verification of flow through the valve will provide assurance that the valve has opened sufficiently to perform its safety function.

OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open or partially open position required to fulfill its safety function.
Reason for Exception These valves can only be full-stroke open exercised by directing auxiliary feedwater flow into the steam generator. The initiation of auxiliary feedwater flow during power operation would result in unwanted thermal shock to the secondary portions of the steam generators. Additionally, the introduction of cold water to the steam generator would cause an unwanted power transient.
Main feedwater flow cannot be used to exercise this check valve during normal power operation due to the thermal shock that would occur by injecting the cooler, stagnant water in the connecting piping. Flow instrumentation is not available in this configuration to verify that the valve has been properly exercised.

- 1. Remain closed to preserve the integrity of the reactor coolant pressure boundary.
- 2. Open to depressurize the RCS to cold shutdown conditions and to mitigate transients/accidents such as MSLB and FWLB.
- 3. Open during the long term cooling mode following a SBLOCA to satisfy LHSI pump minimum flow requirements.
- 4. Open in response to COMS to provide overpressure mitigation for the RCS and prevent pressure-temperature conditions from exceeding Appendix G limits.
OMa 4.2.1.1 requires that each active Category B valve be tested nominally every three (3) months for operational readiness.
The operability testing (full-stroke open and close exercise) of these valves during normal power operation would require closing the associated block valve to prevent an undesirable RCS pressure and pressurizer level transients.
Failure of the valve to properly reseat after the open and close exercise test would require the block valve to be closed and entry into a Limiting Condition for Operation with a possible plant shutdown being required.
These valves will be full-stroke open and close exercised, stroke-timed, and their fall-safe actuation verified at each cold shutdown not to exceed once every three months per the requirements of OMa 4.2.1.2 Monday, October 14, 2002 Page 3 of 23

Test Exception Number Test Exception Type PRR-01 Pump Relief Request Group EWPP EW Pumps Safety Function Takes a suction from the Emergency Cooling Pond and delivers cooling water to Emergency Diesel Generator heat exchangers, Essential Chillers, and Component Cooling Water heat exchangers during normal operating, shutdown, and following accident conditions. The ECW pumps receive an auto start signal upon an SI initiation signal.
Design Flow: 19,280 gpm (per DBD)
Code Requirement OMa Part 6, 5.2.1(b) requires the system resistance to be varied until the flow rate equals the reference point. The differential pressure shall be determined and compared to its reference value. Alternatively, the flow rate shall be varied until the differential pressure equals the reference point and the flow rate determined and compared to its reference value.
OMa Part 6, 5.2. 1(c) states that where system resistance cannot be varied, flow rate and pressure shall be determined and compared to their respective reference values.
Reason for Exception The Essential Cooling Water System is designed so that total pump flow cannot be readily adjusted to one reference value for testing without adversely affecting the operating system flow balance or utilizing excessive operator resources which would be better utilized to monitor the safe operation of the plant. These pumps must be tested in a manner that does not adversely affect the flow balance and system operability.
System resistance is not fixed since each load has an acceptable flow range.
Adjusting system total flow to meet a specific reference value may change the individual load flow rates and may cause one or more of the loads to move outside its respective operation range possibly requiring an entry into an LCO.
Additionally, STP has specific "cold" and "warm" weather lineups for operation of the essential chillers creating a different system resistance.
Consequently, adjusting flow to one specific value on a quarterly basis for the performance of pump testing conflicts with system design and challenges the system operability.
Alternate Testing As an alternative to the testing requirements of OMa Part 6, 5.2.1, STP will assess pump performance and operational readiness through the use of reference pump curves. Flow rate and pump differential pressure will be measured during inservice testing in the as found condition of the system and compared to an established reference curve. The following elements will be used in the development of the reference pump curves:
Monday, October 14, 2002 Page 6 of 23
PRR-01 Continued
- 1. A reference pump curve (flow rate versus differential pressure) will be established for each of the ECW pumps for the data taken when these pumps are known to be operating acceptably.
- 2. Pump curves will be established from measurements taken with instrumentation meeting or exceeding the accuracy requirements of OMa Part 6,4.6.1.1.
- 3. Each Pump curve will be based on at least 5 points beyond the flat portion of the pump curve in the normal operating range of the pumps (at a flow greater than 15,700 gpm). Rated capacity of these pumps is 19,280 gpm.
The pumps will be tested over the range of their full design flow rates, 15,700 gpm minimum to 20,610 gpm maximum.
- 4. The reference pump curves will be based on flow rate versus differential pressure. The acceptance criteria (acceptable and required action ranges) curves will be based on the differential pressure limits of OMa Part 6, Table 3b.
- 5. Vibration levels will be measured at each of the reference points. If negligible variation readings are observed over the range of pump conditions, a single reference value may be assigned to each vibration measurement location. If vibration levels change over the range of pump conditions, appropriate acceptance criteria will be assigned to regions of the pump curve.
- 6. After any maintenance or repair that may affect the existing reference pump curve, a new reference curve shall be determined or the existing pump curve revalidated by an inservice test. A new pump curve shall be established based on at least 5 points beyond the flat portion of the pump curve.

Code Requirement OMa-1988 Part 6, Paragraphs 4.6.1.1 and 4.6.1.2 require pressure instrumentation requirements for accuracy and range. Accuracy must be
+/- 2% and full-scale range shall be not greater than three times the reference value.
Reason for Exception The installed suction pressure gauges for the Component Cooling Water pumps have a range of 160 psig and an accuracy of 0.5%. The reference values for suction pressure for these pumps have been as low as 21 psig. The installed suction pressure gauges for the Component Cooling Water pumps have a full-scale range greater than 3 times the reference value, but have an accuracy of +/- 0.5%, which is more conservative than the Code. The combination of the range and accuracy of the installed suction pressure gauge yields a reading at least equivalent to the reading achieved from instruments that meet the Code Requirements. The installed suction pressure gauge meets the intent of the Code requirements and provides for an acceptable level of quality and safety for inservice testing.
Alternate Testing The permanently installed suction gauges for Component Cooling Water pumps 1A(2A), 1B(2B), and 1C(2C) will be used to obtain test measurements for evaluating pump operability.

OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open, or partially open position required to fulfill its safety function.
Reason for Exception Alternate Testing These check valves cannot be exercised during normal power operation since the HHSI pump cannot overcome normal RCS pressure. These valves cannot be exercised at cold shutdown due to the possibility of over-pressurizing the Reactor Coolant System.
Per OMa 4.3.2.2.e, these check valves will be exercised, full stroke open, each refueling outage by injecting HHSI flow into the open RCS with a vent path established.

Code Requirement OMa 4.3.2.1 requires check valves to be exercised nominally every three (3) months. OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open, or partially open position required to fulfill its safety function.
Reason for Exception These check valves cannot be exercised during normal power operation (full or partial stroke open) since neither the HHSI, LHSI, RHR pump, or Accumulators can overcome normal RCS pressure. These valves cannot be exercised at cold shutdown due to the possibility of over pressurizing the RCS.
Alternate Testing Per OMa 4.3.2.2.e, these check valves will be exercised, full stroke open, each refueling outage using non-intrusive techniques to ensure no degradation has occurred. If any check valve tested during the refueling outage shows signs of unacceptable degradation or performance, it will be disassembled and inspected during that refueling outage.

- 2. Close to prevent backflow to the RWST when containment sump isolation valves are opened during switchover from the injection phase to the cold leg recirculation mode before SI-MOV001A, B, and C are closed. Operator action is required to manually close SI-MOV001A, B, and C to complete the switchover process.
Code Requirenment OMa 4.3.2.1 requires check valves to be exercised nominally every three (3) months. OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open, or partially open position required to fulfill its safety function.
Reason for Exception These check valves can only be exercised, full stroke, by simulating LOCA conditions and allowing the above pumps to inject flow into the RCS at zero or a very low pressure. These conditions can only be simulated during a refueling outage with the reactor vessel head off and the containment spray pump on full recirculation.
Closure of these check valves cannot be verified by non-intrusive means.
There are no external position indicators on these valves and due to the soft closure of these valves (result of pump coastdown) acoustic methods are not conclusive. Magnetic methods are also not conclusive.
Draindown of a portion of the safety injection system is required t perform disassembly and inspection of the valves. Disassembly and inspection can only be accomplished during the 7-day Safety Injection System LCO window or during refueling outages.
Local leakage rate testing of other SI valves and other maintenance activities are now being conducted during the 7-day SI system LCO windows.
Conducting the disassembly and inspection of these check valves in conjunction with LLRTs or other maintenance activities would accomplish the following:
a) Increase the availability of the Safety Injection System during refueling outages, which would lower the overall risk during the outages. The online risk should not be increased if performed during the AOT window since the SI Train will already be removed from service for LLRTs or other maintenance.
Monday, October 14, 2002 Page 12 of 23
ROJ-03 Continued Alternate Testing b) Radwaste should be reduced as the inspections will be performed with other draindown work during the LCO week.
c) There will be a reduction in outage manpower and resource requirements for both maintenance and operations personnel.
d) A reduction in radiation exposure should be realized because personnel will have to perform drain and fill operations only once.
Per OMa 4.3.2.2.e, these check valves will be exercised, full stroke, each refueling outage by injecting flow into the RCS with the vessel head off and the CS pump on full recirculation.
For closure verification, per OMa 4.3.2.4.c, if other test methods are impractical, a sample disassembly examination program shall be used to verify valve obturator movement. At least one check valve from the sample group will be verified operable by disassembly and inspection on a nominal refueling cycle frequency of 18 months (+/- 25%). This will not result in a reduction in the number of inspections performed over the life of the plant. If a generic failure occurs, a plan of action for inspection the remaining valves will be developed utilizing the Condition Reporting Process and the guidance provided in Generic Letter 91-18. This plan of action will take into account the potential failure modes and their associated plant impacts and will be implemented in a time frame commensurate with their safety significance.
This will ensure that all check valves in this sample group are inspected within six years as required by Generic Letter 89-04, Position 2. Approval of this Relief Request safety function will not preclude STP from performing these inspections during refueling outage should some other scope of work make it necessary to drain a train of SI.

Reason for Exception These valves are solenoid valves for which stem movement cannot be directly observed. They are redundant valves in series and operate simultaneously from a single control switch with one set of indicating lights.
Alternate Testing These valves are stroked and timed during normal inservice testing using the remote indicating lights. Open and closed indication is actuated by the limit switches of each valve wired in series and remote position indication is based on the slowest valve. Since these redundant valves cannot be exercised separately (unless leads are lifted, temporary power supplied to the disabled valve to hold it in the open position, and jumpers placed across the disabled valve's limit switches) the valves will be stroked simultaneously and remote position indication verified by observing that system flow is initiated and then secured.

These redundant valves cannot be exercised separately (unless leads are lifted, temporary power supplied to the disabled valve to hold it in the open position, and jumpers placed across the disabled valve's limit switches).
Based on the guidance on NUREG 1482, an evaluation was performed and it was determined that only one valve is required to satisfy the plant safety analysis. Both valves will be included in the IST plan.
Since these redundant valves cannot be exercised separately, the valves will be stroked simultaneously and timed using the remote position indication of the slowest valve. Failure to meet the stroke time acceptance criteria of OMa 4.2.1.8 shall be treated as a failure of a series valve pair and corrective actions taken to determine the cause of the failure.

- 2. Open to recirculate borated water from the containment sump to the RCS hot legs during the hot leg recirculation phase of safety injection.
- 3. Close and be leak-tight (CAT A) to provide containment integrity.
OMa 4.3.2.1 requires check valves to be exercised nominally every three (3) months. OMa 4.3.2.2 requires that each check valve be exercised or examined in a manner that verifies obturator travel to the closed, full-open, or partially open position required to fulfill its safety function.
These check valves have a safety function in the closed direction as containment isolation valves. There are no intra or intersystem cross-ties downstream of these valves which would cause a diversion of flow from another pump if the check valve did not close. Due to the fact that there are no cross-ties downstream of the valves, the valves lack design provisions for system testing to verify closure capability in any plant condition.
Leak rate testing verifies valve closure by validating the valve seats properly and is leak tight, and provides more information about the closed position than a simple backflow test.
NUREG 1482, Section 4.1.4, allows the extension of the test interval to refueling outage frequency for check valves where the only practical means of verifying check valve closure is by performing the Appendix J Leak Test.
STP has adopted Option B of Appendix J that allows these check valves to be leak tested on a frequency not to exceed once every five years.
Disassembly provides limited information on a check valve's ability to seat properly on cessation of flow. Following re-assembly, the Code requires a post-assembly test, which would reopen the check valve without providing assurance the disk would return to the closed position. Disassembly of these check valves is not practical due to the design complexity of the check valves, the increased probability of human error during valve re-assembly, foreign material exclusion concerns, and ALARA considerations.

IST RANK DISCUSSION These valves are normally open. The MOV fails In the existing or normal position. The greatest risk is associated with the function to allow CCW flow. Since these valves are normally open, this function is satisfied without operation of the valve. Reopening of the valve would require a previous need for closure and there are three trains to supply CCW. It would take more than one failure to fail this function.

IST RANK DISCUSSION Valve open function required for post-accident heat removal. Redundancy available in other trains. MOVs In line provide redundant closing function. Additionally, the valve is in a physically closed system whose piping is higher design pressure than containment pressure and the CCW system is not connected to the reactor coolant pressure boundary. Based on the amount of redundancy available for this function the FV is less than 5E-03 and an IST rank of Low is reasonable. However, the RAWis Medium as a result of the industry failure rate data. The failure rate data In the current PRA results in a larger contribution to the common cause calculation which is Included In the RAW number. The RAW may be reduced when the new industry failure rate data for check valves is included in the PRA update. This valve group will remain ranked IST MEDIUM until new PRA model is approved.

Close to prevent CCW overpressurization from flow of the RCS Into the CCW system In the event of failure of the thermal barrier.
NOTE: This valve is a normally open, cylinder-actuated, self-regulated globe valve. The process water is used as the input signal to the actuator. The valve starts to close when the pressure of the process water reaches 120 psig. The valve Is fully closed, but not seated at 150 psig. The valve shuts off at a pressure of over 200 psig.
PRAFUNCTIONS Modeled to remain open DETERMINISTIC REMARKS Close on increasing pressure to isolate CCW system from possible backflow from the RCP thermal barrier. Remains open to provide cooling water to the RCP thermal barner.
Thermal barrier failure Is a highly unlikely event. Redundant closing function is provided by valves in series.
Discussioni (The following general IST ranking notes apply to this valve group)
PRA models valve to stay open. Open is not an active function.
Note 1. Above average Redundancy allows for one failure but maintains Defense in Depth. Close function would be lost only if there was a previous failure of the RCP thermal barrier and two valves In series both failed to close.
Note 3. Valve is normally open and does not have to reposition to allow CCW flow, which is the safety function ranked medium by GQA. Valve closes if system pressure Increases due to a RCP thermal leak.
IST RANK DISCUSSION Function of the valves Is to mitigate thermal barrier failure. These valves do not play a role In any other accident or transient. Ranking of IST Low is based on the normal position of the valve is open to allow CCW flow to cool RCP thermal barriers. Valve failure would not prevent CCW flow. Double Isolation valves provide redundant closing capability to mitigate infrequent event.

During a SGTR and one fails to close, there are two separate trains of solenoid valves that could be used to force the valve to close. From the CR, the close signal will isolate the air supply and vent the air off of the operator to force the valve to close. For all other events, if the break occurs upstream of the valve, we do not want multiple SGs feeding the break. This means that more than one of the MSIVs would have to fail, an unlikely event Discussion (The following general IST ranking notes apply to this valve group )
PRA models the valve to remain open or fail to transfer to the closed position. Valve is normally open and fails closed.
Note 1. Valve fails closed and has two trains of solenoid valves that can be used to close the valve. For MS line break, two valves would have to fail to affect more than one SG.
Multiple SGs are available to cooldown RCS.
Note 9. Function Is not called upon until unlikely failure of the Main Steam piping has occurred.

- 1.
Open to permit the removal of heat from the Nuclear Steam Supply System when the MSIVs are closed to mitigate the consequences of a steam line break, feedwater line break, or steam generator tube rupture. When used In conjunction with the Auxiliary Feedwater System, the Main Steam System is used to achieve a safe shutdown condition.
- 2.
Close to Isolate steam generator In response to SGTR during startup operations.
PRAFUNCTIONS Model to open and to close DETERMINISTIC REMARKS Fail safe position is closed.
Of the steam generators receiving feedwater (typically all 4), we only need one PORV to function in order to depressurize. There are 4 available PORVs.
PRA rank is high to remove decay heat. If this does not work, and AFW Is available, the 20 safety valves will help remove decay heat. PRA credits the function of 1 safety valve.
Failing this, the plant will open the primary side and 'create" a LOCA to depressurize. The new PRA model may show that the importance of this valve is low.
Discussion (The following general IST ranking notes apply to this valve group.)
High FV and High RAW Note 1. Above Average Redundancy - Heat can be dissipated using any of four PORVs. Also if Auxiliary Feedwater is available, there are 20 Main Steam Relief Valves that also can perform this function. Closing function is backed up by the PORV block valves, except in case of SGTR concurrent with Core Damage IST RANK DISCUSSION In the case of SGTR, failure to close may challenge containment. Block valves can isolate open PORVs, except In SGTR with core damage due to high radiation. Redundancy in the valves Is available. Steam dumps also provide redundant cooling function in scenarios where MSIVs remain open. High FV and High RAW.

Low steam line pressure, or High negative steam line pressure rate.
PRAFUNCTIONS Not modeled DETERMINISTIC REMARKS Normally closed, except when starting up to warm up the steam lines.
GQA considered this to be of medium importance due to pressure boundary considerations.
Preliminary assessment supports a low ranking.
Discussion (The following general IST ranking notes apply to this valve group)

IST RANK DISCUSSION Mainsteam/feedwater line rupture, high containment pressure Smaller line has less significant Impact than MSIVs. Could only happen when valve Is open. (Not likely In small window with valves are in use during startup) Redundancy in isolating the alternate trains for steam line break.

If the turbine load is low, the 0 percent dump valves and the 10% to 20% dump valves will completely open within 3 seconds to dump steam to the condenser. The steam dump system can dump up to 40% rated steam flow corresponding to 50% external load rejection without a reactor tnp.
If a 2/4 bo-lo Tavg signal is detected, the steam dump valves will close to stop the steam flow to the condensers.
The SDVs modulate, based on the turbine Impulse pressure, to allow extra steam to the condensers.
All flows are equally divided between the 3 condensers to ensure even heat loads. Steam dump valves are non-safety and not Class 1 E powered. These valves are not considered in the accident analysis.
Discussion Steam dump valves are currently not modeled in the PRA. Dump valves are used for decay heat removal and If modeled would probably have a medium rank for the function, but individually the valves would be ranked LOW. STP is analyzed to cool down using the MS PORVs with the MS Isolation Valves closed If modeled the reliance on the MS PORVs could be reduced. Use of dump valves would require that the MSIVs be open or verified open. The plant reliability process will ensure that maintenance and monitoring activities are Identified. Cause determination and corrective actions are performed whenever failures occur.
IST RANK DISCUSSION Other program controls are used to focus plant resources on this valve group. Valves are not High risk, therefore are not being added to the IST program.

Note 2. Separate opening signals and separate power sources provide diversity to assure performance of safety function.
Note 3. The close function to maintain the RCS pressure boundary is a passive function. Reactor Coolant Pressure Boundary valves are closed and leak tested In accordance with the Technical Specifications prior to start up.
Note 4. Low FV (E-05)
Compensatory Measure - No measure available. Valves are not operated during normal operation and are tested during every refueling outage in accordance with Tech Specs.
IST RANK DISCUSSION Failure of these valves to open could affect decay heat removal. However, redundancy of opening function is provided by other trains. RHR is the preferred method of long-term decay heat removal. It Is not required for early accident mitigation. RHR is required for shutdown. Normally operate two trains to maintain RCS temperature below 140 to avoid inadvertent mode change; however, only one train Is required. Valve Is required to reclose to isolate excessive leakage in RHR train. Valves are closed and leak tested as required by the Technical Specifications. Valves are closed during at power operations. Since the valves will fail in the as-is position, the close function for RCS pressure boundary is a passive function. During cold shutdown operation, the closure function can be performed by the redundant RHR suction MOV. Pipe break risk is low for the RHR suction line with the exception of the first weld, which can see a thermal transient.

This valve is opened, placed In the power lockout position, and its power supply breaker Is opened to ensure the valve remains in the open position during normal plant operation.
Close to demonstrate the ability to allow safety grade cold shutdown utilizing RHR.
Closed and locked out to prevent Inadvertent actuation during shutdown.
Discussion (The following general IST ranking notes apply to this valve group.)
Accumulators are not credited by PRA, Open function Is Passive. Open function is ranked high by GQA. Close function Is ranked low.
Note 1. Above average Redundancy allows for one failure but maintains Defense In Depth. (Three valves would have to fail to fail the function)
Note 3. Valve is opened, placed In power lockout position, and its power supply breaker is opened to ensure the valve remains in the open position during normal plant operation. It cannot be repositioned and the MOV fails as-is in the open position, which is the function ranked high by GQA.
Note 6. Testing of passive open safety function is not required by IST, but It Is listed as an augmented test in the program.
IST RANK DISCUSSION Function to remain open during normal plant operation and to close during shutdown to isolate the accumulator. If valve fails to close, Ops can vent nitrogen off (in EOPs). These valves are open during modes 1-4 and their power supply is locked out. This makes the open function passive since the valve does not have to reposition to perform function required during modes 1-4. The valves are closed when entering mode 5 and their power supply is again locked out (after valve closure). This makes the close safety function also passive during shutdown operation. These valves are not routinely repositioned during normal operations.

- 1. Open to provide a source of borated water to the suction of the LHSI, HHSI and CS pumps during the injection mode of accident mitigation (Flow rate required is 5920 gpm This Is a combination of 1470 gpm for HHSI, 2550 gpm for LHSI, and 1900 gpm for CS).
- 2.
Close to prevent backflow to the RWST when containment sump Isolation valves are opened during switchover from the injection phase to the cold leg recirculation mode before SI-MOV001A, B, and C are closed. Operator action is required to manually close SI-MOV001A, B, and C to complete the switchover process.
PRAFUNCTIONS Modeled to open and close DETERMINISTIC REMARKS Open to provide a source of borated water to the suction of the LHSI, HHSI and CS pumps during the injection mode of accident mitigation Close to prevent backflow to the RWST when containment sump isolation valves are opened during switchover from the Injection phase to the cold leg recirculation mode before SI-MOV001A, B, and C are closed. Operator action Is required to manually close SI-MOV001A, B, and C to complete the switchover process.Active for both directions. Considered to be the pnmary isolation. MOV provides the same closing function. If the valve fails to open, the plant loses 1/3 of SI capacity. Procedurally, the plant needs 1 out of 3 trains for success. RAW is very high. CCF contribution is very high.
Discussion (The following general IST ranking notes apply to this valve group.)
Low FV and High RAW. Open function Is ranked high by GQA. Close function is ranked low.
Note 1. Above average Redundancy allows for one failure but maintains Defense In Depth (Three valves would have to fail to fail the function)
Note 7. High RAW Is due to high CCF for check valves.
Note 8. Industry data has shown that check valves are reliable. Use of the Industry data in the PRA model will reduce CCF term in RAW for check valves in clean systems.
Note 12. Valve group will remain High until new PRA model is approved.
IST RANK DISCUSSION Valve function is to close to isolate the RWST from the containment sump during switchover from the injection mode to the cold leg and hot leg recirculation modes. Redundant closing function is provided by upstream MOV. Based on the amount of redundancy available for this function the FV is less than 1 E-03 and an IST rank of Medium is reasonable.
However, the RAW is High as a result of the industry failure rate data. The failure rate data in the current PRA results in a larger contribution to the common cause calculation which is included in the RAW number. The RAW will be reduced when the new industry failure rate data for check valves is included in the PRA update. This valve group will remain IST Rank High until new PRA model is approved.

PRAFUNCTIONS If failed function, accumulator would fail to discharge. PRA does not credit accumulator for ECCS, as it doesn't prevent or mitigate core damage. PRA does not model.
DETERMINISTIC REMARKS Open when the RCS pressure falls below the accumulator pressure to force borated water into the RCS cold legs. Close to prevent backflow from the RCS into the low pressure SI system. Close and be leak tight (CAT A) to maintain RCS pressure boundary. There are 2 check valves In series to provide redundant ability to maintain RCS pressure boundary Valves are closed and leak tested prior to startup.
Discussion (The following general IST ranking notes apply to this valve group)
PRA - Accumulators are not modeled in the PRA, therefore the FV is low for this function.
Note 1. Above average Redundancy allows for one failure but maintains Defense in Depth. (Three valves would have to fail to fail the function)
Note 3. The close function to maintain the RCS pressure boundary is a passive function. Reactor Coolant Pressure Boundary valves are closed and leak tested in accordance with the Technical Specifications prior to start up.
Note 8. Industry data has shown that check valves are reliable. Use of the Industry data In the PRA model will reduce CCF term In RAW for check valves in clean systems.
IST RANK DISCUSSION A failure to open removes 1/3 of accumulator injection. PRA does not model the accumulators therefore FV is low. Redundancy of function provided by other trains. Failure to close affects RCS pressure boundary. The close function to maintain the RCS pressure boundary is a passive function. Reactor Coolant Pressure Boundary valves are closed and leak tested in accordance with the Technical Specifications prior to start up. Redundant valves maintain RCS pressure boundary.
