ASME SECTION XI CODE BOUNDARY DRAWINGS The ASME Code Classification Boundary Drawings, PG&E Number 102028 (Unit 1) and 104628 (Unit 2),

are located in Section 2.0 of the Inservice Inspection (ISI) Program Plan. Regulatory Guide 1.261 was used as the governing document in setting up the Inservice Inspection and Testing Program (ISIT) boundary. The drawings show the Code Class 1, 2, and 3 systems and components subject to inservice inspection and testing requirements. Systems and components are identified by Code Class and are color coded as applicable to indicate exemptions from various code requirements2. These drawings are extracted from the piping schematics (P&ID's) for the plant that are contained in Section 3.2 of the FSAR. All ASME Code Class 1, 2, and 3 components subject to inservice testing are shown on the drawings. To emphasize the Section XI Code Boundaries, P&ID pages containing lines other than ASME Code Piping have been omitted and non-ASME lines have been ghosted on the pages included. An explanation of the color coding system is provided at the end of the drawings.

Pacific Gas and Electric Company Revision 0 77 Beale Street January 7, 2005 San Francisco, California 94177 INSERVICE TESTING OF PUMPS AND VALVES The pump and valve testing program demonstrates the operational readiness of Code Class 1, 2, and 3 pumps and valves which are required to perform a specific function in shutting down the reactor to the safe shutdown condition, in maintaining the safe shutdown condition or in mitigating the consequences of an accident. This program is presented in the attached Tables.

Table 1.0 (Pump IST Program) includes the pump name and number, the Code Class, applicable surveillance test procedure and test parameters, i.e., speed, differential pressure, discharge pressure, flow rate, pump bearings vibration, applicable relief request numbers, and remarks.

Table 1.1 contains all of the pump requests for relief from Code requirements.

Table 2.0 (Valve IST Program) includes the system name and number, valve number, description, P&ID coordinates, Code class, Code category, size, valve type (ball, butterfly, check, diaphragm, gate, globe, plug, or relief valve), actuator type (air operated, electric motor, electrohydraulic, manual, or solenoid-operated), normal valve position, test requirements, the test frequency, applicable stroke time and direction, relief request number (or cold shutdown or refueling outage justification numbers), procedure number, and remarks.

Table 2.1 contains all valve cold shutdown justifications per OM Code, ISTC-3521(c), and ISTC-3522(b).

Table 2.2 contains all valve refueling outage justifications per OM Code, ISTC-3521(e), ISTC-3522(c), and ISTC-522 1 (c)(3).

Table 2.3 contains all of the valve requests for relief from Code requirements.

Pacific Gas and Electric Company Revision 0 77 Beale Street January 7, 2005 San Francisco, California 94177 HOT STANDBY AS THE SAFE SHUTDOWN CONDITION OM Code, ISTA I 1 00(a) defines the scope of the IST Program to include pumps and valves that are required to perform a specific function in shutting down a reactor to the safe shutdown condition, in maintaining the safe shutdown condition or in mitigating the consequences of an accident. Safe shutdown at Diablo Canyon Power Plant is defined as HOT STANDBY. DCPP SSER 7, page 3-3 and SSER 22, pages 93-95 indicate that DCPP is considered to be a Class 2 plant wherein a single suction line from RCS Hot Leg is considered acceptable since the plant has a safety related Auxiliary Feedwater system enabling decay heat removal for extended periods at Hot Standby. Technical Specification Bases B 3.3.4 states, "safe'shutdown condition is defined as MODE 3. With the unit in MODE 3, Auxiliary Feedwater (AFW) System and the Steam Generator (SG) safety valves can be used to remove core decay heat and meet all safety requirements."

Hence, DCPP is considered to be a Hot Standby plant.

The component cooling -vater (CCW) system removes heat from safety-related and nonsafety-related system components during normal operation and plant shutdown and transfers it to the ultimate heat sink via the auxiliary salt~water (ASW) system. The CCW pumps (CCWPs) are horizontally mounted centrifugal pumps.

The CCW system provides for safe shutdown and cooldown of the reactor by removing heat from safety-related and nonsafety-related system components after normal reactor shutdown, and from vital system components after an accident leading to an emergency shutdown.

Test Requirement ASME OM Code, subsection ISTB-5121(b) and ISTB-5123(b). The resistance of the system, shall be varied until flow rate equals the reference point.

Basis For Relief A variable flow measurement for the CCWP test is required because it is impractical to establish a fixed reference value(s). Relief is requested per IOCFR50.55a(f) (5) (iii). Diablo Canyon Power Plant (DCPP) had previously received relief for these pumps in the first and second 10 year plans.

REQUESTS FOR RELIEF FROM CODE REQUIREMENTS PAGE 3 OF 6 NO. P-RR1(cont.)

The CCW system has varying heat loads, and therefore varying flow requirements. A full flow test line with a single throttle valve for the purpose of testing was not incorporated in the initial design of the system. For some plant conditions, a reference flow condition cannot be established without adversely affecting the system flow balance and Technical Specification (TS) operability requirements. Thus, these pumps must be tested in a manner that the CCW system remains properly flow balanced during and after the testing and each supplied load remains fully operable per TS to maintain the required level of plant safety during power operation. During refueling outages, CCW flow demand varies greatly due to reactor coolant system cooldown, clearing of components for maintenance, and spent fuel pool heat exchanger cooling water demand. Past experience at DCPP has shown that CCW flow during refueling outages is usually greater than flow during power operations and it is not practical to reduce flow in order to perform the CCWP IST.

At a minimum, perturbation of multiple systems is required to establish a-flow point due to the multiple flow paths of the CCW system. This abnormal configuration would have to be maintained for the length of time required to take vibration data and pump hydraulic data. In addition, the requirement for the Operators to manipulate valves required to adjust CCW flow to the reference point is adverse to ALARA.

Alternative Test Perform inservice tests on CCWPs using the following. A reference pump curve (flow rate vs. pump head) has been developed for each of the six CCWPs.

The following elements will be performed in developing the pump curves for testing the CCWPs. Existing data from previously performed inservice tests may be used in developing the curves. If a pump is replaced or repaired in such a way that inservice test parameters would require new reference values, then a preservice test performed per ISTB-5 100 would be used to develop the new reference pump curve and reference vibration values.

I. Pump reference curves will be developed when the pumps are known to be operating satisfactorily.

2. Instrumentation used to develop pump curves is at least as accurate (accuracy and range) as required by ASME OM Code Table ISTB-3400-1
3. Pump curves will be constructed using a minimum of five points.
4. Points used to construct the curves are beyond the flat portion (low flow rates) of the pump curve in a range, which includes the design bases flow rate.
5. Acceptance criteria for flow rate and differential pressure will be established by taking the more conservative of curves based on the limits of Table ISTB-5 100-1, or the operability criteria in TS or Safety Analysis Report.
6. Vibration levels will be measured over the range of pump conditions, and appropriate vibration acceptance criteria based on ISTB-5100-1, will be assigned for regions of the pump curve.
7. A new reference curve will be prepared by performing a preservice test procedure in accordance with ISTB-51 10, or the previous curve will be validated, if the pump curve is affected by replacement, repair, or routine service.
8. The comprehensive pump test will be performed at a flow that is +/-20% of design flow. Design flow for a CCW pump is 9200 gpm. The group A test will be performed at a flow rate that is at least 80% of design flow.

A Functions:

The auxiliary saltwater (ASW) system supplies cooling water from the ultimate heat sink, the Pacific Ocean, to the component cooling water (CCW) heat exchangers. The CCW system, in turn, removes heat from nuclear primary plant equipment and components during normal plant operation, plant cooldowns, refueling and accident conditions, including a loss of coolant accident.

Each DCPP unit is provided with two redundant ASW trains. Each of these trains consist of a full capacity ASW pump (ASWP) and associated piping to supply the tube side of one of the CCW heat exchangers with cooling water. Each pump may also be cross-connected so as to supply the opposite train heat exchanger.

Test Requirement ASME OM Code, subsection ISTB-5221(b) and ISTB-5223(b). The resistance of the system, shall be varied until flow rate equals the reference point.

Basis For Relief Adjustment to a specific reference value for the ASWP test is not practical because the pump flow rate varies based on tide level (suction pressure) and heat exchanger differential pressure (system resistance),

which cannot be readily controlled. The CCW heat exchanger outlet throttle valves are the only valves which can be adjusted to set ASWP flow at the desired test flow. These valves are sealed in a throttled position which ensures the train can perform its required safety function under worst case conditions. A CCW heat exchanger is considered inoperable after its outlet valve is adjusted until a flow verification test is performed. The flow verification test requires that the system alignment with the most system resistance i.e.,

ASW pump #I to CCW heat exchanger #2 (or ASW pump #2 to CCW heat exchanger #1 ) be used. This realignment, test and subsequent data analysis takes several hours, during which time the CCW heat exchanger is inoperable. Diablo Canyon Technical Specifications require that the second vital CCW heat exchanger be placed in service whenever ultimate heat sink temperature is greater than 641F. In order to meet the Technical Specification LCO, ASW pump tests performed when ultimate heat sink temperatures are above 641F must be performed with two CCW heat exchangers in service and result in test flows of up to 14,000 gpm. When the test is run with only one CCW heat exchanger in service (normal test alignment),

reference pump flow is between 11,500 and 12,500 gpm. Relief is requested per 10CFR50.55a(f) (5) (iii).

STROKE TIME (STR TIM)

For power operated valves, the maximum allowed stroke time is given in seconds followed by a "c" for closing, or an "o" for opening, or an "o/c" for both opening and closing. For manual valves and check valves, this column denotes that the valve has a safety function in the "c" closed position, in the "o" open position, or in both the "o/c" open and closed position.

RELIEF REQUEST (REL REQ)

Numbers in this column refer to either a cold shutdown justification (CS), a refueling outage justification (RO), or a relief request (RR). These justifications and relief requests are found in TABLES 2.1, 2.2, and 2.3 respectively.

PROCEDURE NUMBER (PROC NO.)

Identifies procedure used to meet test requirement. If valve is stroked routinely during normal operations, then NORM OP.

REMARKS The numbers in the remarks column refer to the list of remarks on the last page of TABLE 2.0.

  1. f2 The leak tests for valves FW-367,368, 531, and 532, are not required by Code as these valves do not have a safety related function to prevent back leakage. The leak test and the categorization as "A,C" is based on a corrective action in NCR DC 1-91 -TN-N002.
  1. 3 FCV-1 IOA does not have an active safety function. The safety related boration flow path is through 8104 and the redundant flow path is from the RWST. However, in the Appendix R and Hosgri evaluations credit was taken for this valve to open or fail open so this valve is being administratively included in the IST program as a conservative measure since it may be considered a licensing commitment.

FCV-438 Steam Generator #I Feedwater Isolation Valve FCV-439 Steam Generator #2 Feedwater Isolation Valve FCV-440 Steam Generator #3 Feedwater Isolation Valve FCV-441 Steam Generator #4 Feedwater Isolation Valve Category:

B Code Class: 2 Function:

The check valves have an active function to close to prevent backflow so that AFW pump discharge flow will be directed to the steam generators as required when the AFW system is actuated.

The isolation valves have an active safety function to close to terminate continued feedwater flow to the steam generators or to a faulted feedwater line inside containment as assumed in the plant accident analysis.

Basis:

These Main Feedwater Check Valves and Feedwater Isolation Valves cannot be exercised during power operation because closing these valves would require securing feed flow to a steam generator which would result in a reactor trip.

Part stroking is not considered practical because of the risk of full closure. The risk is recognized in DCPP's Technical Specification Bases Document for Technical Specifications Surveillance Requirements 3.7.3.1 and 3.7.3.2, which states "These surveillances are normally performed upon returning the unit to operation following a refueling outage. These valves should not be tested at power since even a part stroke exercise increases the risk of a valve closure with the unit generating power."

Justification:

Cold shutdown frequency testing is per ISTC-3522(b) and ISTC-3521(c).

These valves have an active safety function in the open direction to permit the flow of water from the AFW pump discharge lines to the steam generators. Second off check valves FW-369, FW-370, FW-371, FW-372, FW-373, FW-374, FW-375, and FW-376 also have a safety function to close to prevent the backflow of feedwater through an idle AFW pump.

Basis:

These Auxiliary Feedwater Supply Check Valves cannot be full stroke exercised during power operation because the only available flow path is into the steam generators which could result in thermal shock to the associated piping and fittings. These valves will be full stroke exercised during a shutdown to, or a startup from, a cold shutdown condition.

Justification:

Cold shutdown frequency testing is per ISTC-3522(b).

B Code Class: 2 Function:

These valves have an active safety function to automatically close on high steam flow, coincident with either low-low T(avg) or low steam pressure, or on a high-high containment pressure signal.

Basis:

These valves cannot be full stroke exercised during power operation because this would require securing steam from a steam generator which would result in a reactor trip, and most likely a safety injection.

Part stroke testing capability does exist for these valves but is not considered practical, since extremely limited (60 max., 20 nominal) valve motion is allowed due to the valve design which only provides verification that the valve is not frozen in the open position. Additionally, as a result of the valve design, performing partial stroke testing exposes the plant to an inadvertent Reactor Trip and/or Safety Injection should the valve stroke more than 60 (resulting in a flow assisted closure of the valve).

These valves will be full stroke exercised on a cold shutdown frequency.

Justification:

Cold shutdown frequency testing is per ISTC-3521(c).

B Code Class: N/A Function:

These valves have an active safety function to close to isolate the volume control tank from the suction of the charging pumps upon the receipt of a safety injection signal.

Basis:

These isolation valves should not be full or part stroke exercised during power operation because failure of either valve in the closed position would result in a loss of reactor system level control or injecting 2000 ppm boric acid solution from the RWST into the reactor coolant system, resulting in a possible plant shutdown.

A Code Class: 2 Function:

These valves have an active safety function to close to isolate the seal water return line containment penetration upon receipt of a Phase A containment isolation signal.

Basis:

These isolation valves cannot be exercised during power operation because this would challenge the relief valve in the RCP seal water return line. If this relief valve failed in the open position, this would result in unnecessary reactor coolant system leakage.

These motor operated valves cannot be part stroke tested because the control system does not allow for part stroke testing.

Function:

These valves have an active safety function to close to isolate the high pressure safety injection flow path from the CVCS during safety injection system operation following a LOCA.

Basis:

These valves should not be exercised during power operation because failure of either valve in the closed position could result in pump damage if a secondary system accident occurred.

These motor operated valves cannot be part stroke tested because the Bases for Technical Specification Surveillance Requirements 3.5.2.1 and 3.5.2.2 require that these valves be maintained open.

Justification:

Cold shutdown frequency testing is per ISTC-3521(c).

B Function:

These redundant, motor-operated gate valves have an active safety function to close to isolate the normal charging flow path from the high pressure safety injection flow path upon receipt of a safety injection signal.

Basis:

These valves should not be full stroke exercised during power operation because failure of either valve in the closed position could result in loss of reactor coolant system level control, which could result in a plant shutdown. The control scheme for these motor operated valves does not allow for part stroking. Also, failure of either of these valves in a closed position would place the plant in an LCO action statement due to a loss of the boration flow path from the boric acid tanks.

Air operated globe valves 8145 and 8148, have an active safety function to open during plant cooldown to cooldown the pressurizer when normal pressurizer spray is inoperable. This is not an accident mitigation function but a safe shutdown function following a Hosgri earthquake.

Basis:

These valves should not be full stroke exercised during power operation because failure of eithervalve in the open position could result in a loss of reactor coolant system pressure control which could result in a plant shutdown. The control scheme for these air-operated valves does not allow for part stroking.

These air operated globe valves have an active safety function to close to provide containment isolation and to isolate a high energy letdown line break outside containment upstream of the letdown heat exchanger.

Basis:

These valves will not be full stroke exercised during power operation due to the following causes: thermal transients on the regenerative letdown heat exchanger, hydraulic transients on the letdown line; pressure control transients resulting in the lifting of relief valve RV-8117; and charging nozzle temperature transients when charging is isolated during letdown testing.

A Code Class: 2 Function:

These motor operated gate valves have an active safety function to open to provide a flow path for the safety injection pumps in the Hot Leg recirculation mode.

Basis:

These valves cannot be full or part stroke exercised during power operation because they are required to be closed with power to the valve operators removed by Technical Specification SR 3.5.2.1. If these valves were opened during power operation and an accident were to occur, safety injection flow would go to the hot legs instead of the cold legs. The safety analysis has analyzed for flow going to the cold legs and not the hot legs.

These motor operated gate valves have an active safety function to open to provide a flow path from the refueling water storage tank to the suction of the charging pumps.

Basis:

These valves should not be full or part stroke exercised at power because opening these valves injects highly oxygenated, 2000 ppm borated water from the RWST into the reactor coolant system. Injecting this water results in a negative reactivity addition to the reactor coolant system which could shut the plant down. See also NRC SER dated 1/31/94 addressing LA 86 and 87.

C Code Class: N/A Function:

These check valves have an active safety function to close in the event of a steam line break upstream of the main steam isolation valves. This accident mitigation function is to prevent the blowing down of more than one steam generator.

Basis:

These valves cannot be exercised closed because provisions are not provided in the plant design to verify that these valves close on reverse flow. Therefore, each refueling outage, one of these valves will be disassembled, mechanically exercised and examined on a refueling outage rotational frequency such that one valve shall be disassembled and examined each refueling outage; all four valves shall be disassembled and examined at least once every 8 years.

Basis for Check Valve Sample Disassembly Examination Program:

These check valves are of the same manufacturer, model number, size, orientation and service. They also have similar maintenance and modification histories. Since they are the main steam line check valves, they will be full stroke opened by steam flow from the steam generators during power ascension after each refueling outage.

C Code Class: 2 Function:

These check valves function to supply steam to the turbine driven auxiliary feedwater pump. The valves also have a safety function in the closed (reverse-flow) position to prevent an intact steam generator from blowing down to containment through the turbine driven AFW pump steam supply line following a MSLB.

Basis:

Full stroke opening is verified on a cold shutdown basis when full flow pump test of turbine driven auxiliary feedwater pump is performed, but valve reclosure capability cannot be verified.

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation. There are no test connections or taps installed that would allow reverse-flow seating verification for these check valves. Alternatively, the ability of the valve to close following actuation will be verified by disassembly and internal inspection on a rotational basis, one valve each refueling outage not to exceed an eight year interval between disassembly and inspections for each valve. If any degradation is detected that interferes with the valve's operability, then the opposite train valve will also be disassembled and internally inspected during the same outage.

  • Basis for Check Valve Sample Disassembly Examination Program:

These check valves are of the same manufacturer, size, orientation and service. Unit two valve MS-2-5 167 is essentially the same model as MS-1-5 166, MS-1-5 167 and MS-2-5 166, the only difference being that the equalizing line is orientated on the near side instead of the far side when viewing the valve from the side with flow going from the right to left. They also have similar maintenance and modification histories. Since they are the main steam supply to the turbine driven auxiliary feedwater pump, they will be full stroke opened by steam flow when full testing the auxiliary feedwater pump after each refueling outage.

Justification:

Rotational Refueling outage frequency testing is per ISTC-5221(c)(3).

A, C Code Class: 2 Function:

These check valves serve as containment isolation valves and have the safety function to close to prevent back leakage from containment to system outside of containment. These valves do not have an open safety function.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation. They are located inside containment.

These containment isolation valves can only be verified closed by performing a seat leakage test.

Performance of seat leakage test can not be performed during power operation because it would require breaching containment, setting up test equipment inside containment and personnel would be required to enter containment to perform necessary valve alignments and test equipment setup.

It is impracticable to stroke test these valves during cold shutdown because the only test method to verify closure is to perform a seat leakage test. Personnel would be required to enter containment to perform valve alignments and setup of test equipment for the leak test.

Open stroke tests for these valves need not be performed at an interval when it is not practicable to perform the check valve closure test per ISTC-3522(a).

B Code Class: 2 Function:

These valves have an active function to open to vent noncondensible gases from the RCS, which might inhibit core cooling during natural circulation. They were installed to provide reactor vessel high point vent capability for beyond-design-bases events per the guidance of NUREG 0737 and are not relied upon to mitigate any design basis accidents as defined and analyzed in the FSAR Chapter 15 Accident Analyses.

Basis:

These Reactor Vessel Head Vent Valves should not be full or part stroke exercised during power operation by NRC direction.

Stroke time testing of the Reactor Vessel Head Vent Valves during Cold Shutdown has resulted in borated water from the valves to drip onto the Reactor Vessel Head. The borated water could cause corrosion damage to the Reactor Vessel Head. During Refueling Outages special test equipment is set up inside the Containment Building to flush the Reactor Vessel Head Vent Valves and piping with demineralized water after the stroke tests are complete. Setting up the special test equipment inside containment is impractical during Cold Shutdown forced outages, because the Reactor Vessel head is inaccessible and there would be significant radiation exposure to personnel.

A,C Code Class: 2 Function:

The Bypass Check Valves have a safety function in the open direction of protecting the containment penetrations from over pressurization from thermal expansion of the liquid trapped between the containment isolation valves after an accident that results in an increase in containment temperature. These valves need to only partially open a small amount to fulfill this function. They also serve as containment isolation valves, so they have a safety function in the closed direction to prevent back leakage.

Basis:

These Bypass Check Valves cannot be exercised during power operation because the test would require clearing the reactor coolant pumps which are required for power operations. The tests also require that test equipment be set up inside the containment building.

These valves cannot be tested during cold shutdown because the test requires setting up test equipment inside containment, clearing reactor coolant pumps, and numerous valve manipulations.

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation.

Justification:

Refueling outage frequency testing is per ISTC-3522 (c). Seat leakage testing is the only method of verifying closure. Open stroke need only be performed at an interval when it is practicable to perform the closure test.

C Code Class: I Function:

These valves are the RCS code pressure boundary valves on the RCP seal injection lines. The closing' function of these valves to protect the upstream piping from over pressurization is not considered to be a safety function, at least for the purposes of the IST program, because the upstream piping is designed for, and normally subjected to, pressure higher than RCS pressure. Hence the ability of these valves to close is not a required safety function. RCP seal cooling is considered to be a safety function because a failed seal is considered to be a small break LOCA. For a Main Steam Line Break inside containment, CCW flow to the RCP thermal barrier is isolated. Seal injection is then the only means of providing seal cooling and preventing seal failure. These valves must open to pass seal injection flow. Summary, these check valves have a safety function to open, but do not have a safety function to close.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation.

These check valves are required to be open during normal operation since this position provides normal seal flow to the RCP's. Therefore they cannot be stroked tested in the closed direction during operation of the plant.

These check valves cannot be stroke tested closed during cold shutdown operation because the test would require clearing the reactor coolant pumps, setting up test equipment inside the containment building and numerous valve manipulations. It is not practicable to perform these tests during cold shutdown.

Basis for Testing Series Check Valve Pairs as a Unit:

These valves are arranged so that there are two valves in series to each RCP. There are no test connections between the valves that would enable the valves to be individually tested. They will therefore be tested as pairs in accordance with ISTC-5223.

Therefore, each refueling outage, these valves will be verified closed by performing a backpressure flow test on each pair of valves.

Justification:

Refueling outage frequency testing is per ISTC-3522(c).

Check valve 8377, has an active safety function to open enable use of the auxiliary spray system for reactor shutdown when normal pressurizer spray is inoperable. This is not an accident mitigation function but a safe shutdown function following a Hosgri earthquake.

Basis:

This valve is not equipped with a mechanical exerciser, position indicator or differential pressure instrumentation. The valve is located inside containment.

A flow test of this valve during power operations would require that either air operated globe valve 8145 or 8148 be opened. Failure of either valve in the open position could result in a loss of reactor coolant system pressure control that could result in a plant shutdown.

This check valve cannot be stroke tested closed during cold shutdown operation because the test would require setting up test equipment inside the containment building and numerous valve manipulations. It is not practicable to perform this test during cold shutdown.

The closing function of these valves to protect the upstream piping from over pressurization is not considered to be a safety function, at least for the purposes of the IST program, because the upstream piping is designed for, and normally subjected to, pressure higher than RCS pressure. Hence the ability of these valves to close is not a required safety function. These valves have active functions to open to supply normal and alternate charging to Loop 4 or 3 RCS Cold Legs for emergency boration flow path.

8378C is a containment isolation valve but is exempted from 10CFR50 Appendix J required leak rate testing. It has the same safety function to open as 8378A/B and 8379A/B.

Summary, these check valves have a safety function to open, but do not have a safety function to close.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation. They are located inside containment.

These valves should not be exercised during power operation because this would cause a thermal transient to be induced on the charging to RCS Cold Leg nozzle. This is per Westinghouse Infogram (WIG)90-025.

This check valve has an active safety function to close to prevent backflow from the charging pump suction header to relief valve 8123 during the post-LOCA containment sump recirculation mode of safety injection.

It also has a safety function to open to provide a flow path for the charging pump mini-flow recirculation to return to the suction header of the charging pumps.

Basis:

This valve is not equipped with a mechanical exerciser, position indicator or differential pressure instrumentation.

This check valve is open during operation to provide the normal source of supply to the suction of the charging pumps. Exercising this valve during power operation would require alignment to the alternate supply which would result in injecting highly oxygenated, 2000 ppm borated water into the reactor coolant system. Injecting this water results in a negative reactivity addition to the reactor coolant system which could shut the plant down.

This valve cannot be tested for backflow during power operation as the only acceptable method of testing would be to perform hydros and measure for backleakage. This testing would require clearing pumps, entering ACTION Statements, and numerous valve and pump manipulations which affect the pressurizer level control and letdown temperature. This can cause cavitation in the letdown line.

This valve cannot be tested for backflow during cold shutdown as the only acceptable method of testing would be to perform hydros and measure for backleakage. This testing would require clearing pumps, entering ACTION Statements, and numerous valve and pump manipulations along with setting up the hydro testing equipment. It is not practicable to perform this testing on a cold shutdown frequency, therefore the closure test will be performed on a refueling outage frequency.

The ability to open is proven during normal operations per ISTC-3550. Closure will be tested on a refueling outage frequency.

8483, Charging Flow to Cold Legs Bypass Check Valve Category:

C Code Class: I Function:

This valve has a safety function to open to relieve pressure build up if normal and alternate charging valves 8146 and 8147 are both closed and Regenerative Heat Exchanger added heat to the charging line with resulting thermal expansion and pressure increase. The valve need only to partially open and allow flow to perform its safety function. The valve does not have a safety function to close to prevent back flow.

Basis:

This check valve cannot be exercised during power operation because opening this valve would require closing normal and alternate charging valves 8146 and 8147 which would isolate normal charging. This would result in thermal transient to be induced in the charging to RCS Cold Leg nozzles. This is per Westinghouse Infogram (WIG 90-025).

This valve cannot be tested for flow during Cold Shutdown as the only acceptable method of testing is to isolate normal and alternate charging thus isolating charging flow. The resultant differential pressure seen by 8146 or 8147 would be extremely high because all of the charging pump pressure would have to be reduced at the normal or alternate charging valve which is not set up to accomplish this. The valve can be tested during refueling outages when charging pump full flow tests using charging injection flow path are performed. During the charging pump full flow tests, the pressures differential across the normal or alternate charging valves is much lower.

Justification:

Refueling outage frequency testing is per ISTC-3522(c).

C Code Class: 2 Function:

These valves have the safety function of opening to allow the discharge of boric acid for emergency boration. The boric acid transfer pumps are normally aligned such that only one pump discharges to the boric acid filter, while the other is aligned to recirculate flow to back to the boric acid storage tank. To align the second pump to the common discharge line to the boric acid filter requires local manual operator action, at which time a second local manual isolation valve could be closed if necessary to prevent short circuiting of flow. Hence, operation of these check valves in the closed direction is not considered to be a safety function.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation.

These check valves cannot be backflow tested during power operations or cold shutdown because this test would require that at least one train of boration flow path be cleared, test equipment to be set up and numerous valves to be manipulated. The boric acid transfer system is heat traced to maintain temperature, clearance of this system could result in a long term inoperability of the system.

It is not practicable to perform this test during power operations or cold shutdown.

These check valves have an active safety function to open to supply safety injection flow to the reactor coolant system (RCS) cold legs from the high-head safety injection pumps (centrifugal charging pumps).

Basis:

These valves cannot be full stroke exercised during plant operation because the high RCS pressure will prevent the maximum required injection flow rate.

These valves cannot be full stroke exercised during cold shutdown because of insufficient RCS expansion volume to accommodate the high flow rates required to full stroke these valves. These high flow rates could challenge the RCS low temperature overpressure (LTOP) mitigation system. To prevent challenging the LTOP system, venting of the pressurizer by removal of a safety valve would be required. Additionally, full stroke exercising these valves cannot be performed with a bubble in the pressurizer, because the net charging rate must be minimal to prevent thermal cycling of the pressurizer.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation.

These valves can only be verified closed by performing a seat leakage test using a hydrostatic pump.

Performance of seat leakage test cannot be performed during power operation because it would require closure of the SI Pump recirculation line motor operated valves, which are required by technical specifications to remain open during power operations.

It is impracticable to stroke closed these valves during cold shutdown because the only test method to verify closure is to perform a seat leakage test. Performance of this test requires setup of a hydrostatic pump and associated test equipment for the leak test. The system alignment would render both SI pumps inoperable because the recirculation line would be isolated.

These check valves have the safety function in closed direction of preventing back leakage to maintain design basis containment integrity. The valves have no safety function in the open direction; the ability to provide firewater to the containment, while important, is not considered to be safety related.

Basis:

These valves are not equipped with mechanical exercisers, position indicators or differential pressure instrumentation.

These valves can only be verified closed by performing a seat leakage test. Performance of seat leakage test can not be performed during power operation because it would a breach of containment integrity, require setting up test equipment inside containment and aligning the fire protection system in such a way that the containment fire protection header is isolated.

It is impracticable to stroke closed these valves during cold shutdown because the only test method to verify closure is to perform a seat leakage test. Performance of this test requires setup of test equipment and either isolating firewater to containment building or installing a firewaterjumper'to provide containment firewater flow during the time the header is isolated.

Open stroke tests using flow for these valves require that special fire hoses and headers be installed and routed to a spare containment penetration so that firewater flow can be directed outside containment. This alignment renders both the fire water system and containment integrity inoperable for the duration of the test and until an extensive amount of test equipment removed and plant systems restored. It is not practicable to perform the flow test in either plant operation or cold shutdown.

Therefore open stroke tests are performed on a refueling outage frequency.

The component cooling water (CCW) system removes heat from safety-related and nonsafety-related system components during normal operation and plant shutdown and transfers it to the ultimate heat sink via the auxiliary saltwater (ASW) system. The CCW pumps (CCWPs) are horizontally mounted centrifugal pumps.

The CCW system provides for safe shutdown and cooldown of the reactor by removing heat from safety-related and nonsafety-related system components after normal reactor shutdown, and from vital system components after an accident leading to an emergency shutdown..

Test Requirement ASME OM Code, subsection ISTB-5121(b) and ISTB-5123(b). The resistance of the system, shall be varied until flow rate equals the reference point.

Basis For Relief A variable flow measurement for the CCWP test is required because it is impractical to establish a fixed reference value(s). Relief is requested per IOCFR50.55a(f) (5) (iii). Diablo Canyon Power Plant (DCPP) had previously received relief for these pumps in the first and second 10 year plans.

The CCW system has varying heat loads, and therefore varying flow requirements. A full flow test line with a single throttle valve for the purpose of testing was not incorporated in the initial design of the system. For some plant conditions, a reference flow condition cannot be established without adversely affecting the system flow balance and Technical Specification (TS) operability requirements. Thus, these pumps must be tested in a manner that the CCW system remains properly flow balanced during and after the testing and each supplied load remains fully operable per TS to maintain the required level of plant safety during power operation. During refueling outages, CCW flow demand varies greatly due to reactor coolant system cooldown,'clearing of components for maintenance, and spent fuel pool heat exchanger cooling water demand. Past experience at DCPP has shown that CCW flow during refueling outages is usually greater than flow during power operations and it is not practical to reduce flow in order to perfonn the CCWP IST.

At a minimum, perturbation of multiple systems is required to establish a flow point due to the multiple flow paths of the CCW system. This abnormal configuration would have to be maintained for the length of time required to take vibration data and pump hydraulic data. In addition, the requirement for the Operators to manipulate valves required to adjust CCW flow to the reference point is adverse to ALARA.

Alternative Test Perform inservice tests on CCWPs using the following. A reference pump curve (flow rate vs. pump head) has been developed for each of the six CCWPs.

The following elements will be performed in developing the pump curves for testing the CCWPs. Existing data from previously performed inservice tests may be used in developing the curves. If a pump is replaced or repaired in such a way that inservice test parameters would require new reference values, then a preservice test performed per ISTB-5 100 would be used to develop the new reference pump curve and reference vibration values.

I. Pump reference curves will be developed when the pumps are known to be operating satisfactorily.

2. Instrumentation used to develop pump curves is at least as accurate (accuracy and range) as required by ASME OM Code Table ISTB-3400-1
3. Pump curves will be constructed using a minimum of five points.
4. Points used to construct the curves are beyond the flat portion (low flow rates) of the pump curve in a range, which includes the design bases flow rate.
5. Acceptance criteria for flow rate and differential pressure will be established by taking the more conservative of curves based on the limits of Table ISTB-5 100-1, or the operability criteria in TS or Safety Analysis Report.
6. Vibration levels will be measured over the range of pump conditions, and appropriate vibration acceptance criteria based on ISTB-5 100-1, will be assigned for regions of the pump curve.
7. A new reference curve will be prepared by performing a preservice test procedure in accordance with ISTB-51 1O, or the previous curve will be validated, if the pump curve is affected by replacement, repair, or routine service.
8. The comprehensive pump test will be performed at a flow that is +/-20% of design flow. Design flow for a CCW pump is 9200 gpm. The group A test will be performed at a flow rate that is at least 80% of design flow.

Auxiliary Saltwater Pump 1-1 Vertical Line Shaft 3

A Auxiliary Saltwater Pump 1-2 Vertical Line Shaft 3

A Auxiliary Saltwater Pump 2-1 Vertical Line Shaft 3

A Auxiliary Saltwater Pump 2-2 Vertical Line Shaft 3

A Functions:

The auxiliary saltwater (ASW) system supplies cooling water from the ultimate heat sink, the Pacific Ocean, to the component cooling water (CCW) heat exchangers. The CCW system, in tum, removes heat from nuclear primary plant equipment and components during normal plant operation, plant cooldowns, refueling and accident conditions, including a loss of coolant accident.

Each DCPP unit is provided with two redundant ASW trains. Each of these trains consist of a full capacity ASW pump (ASWP) and associated piping to supply the tube side of one of the CCW heat exchangers with cooling water. Each pump may also be cross-connected so as to supply the opposite train heat exchanger.

Test Requirement ASME OM Code, subsection ISTB-5221(b) and ISTB-5223(b). The resistance of the system, shall be varied until flow rate equals the reference point.

Basis For Relief Adjustment to a specific reference value for the ASWP test is not practical because the pump flow rate varies based on tide level (suction pressure) and heat exchanger differential pressure (system resistance),

which cannot be readily controlled. The CCW heat exchanger outlet throttle valves are the only valves which can be adjusted to set ASWP flow at the desired test flow. These valves are sealed in a throttled position which ensures the train can perform its required safety function under worst case conditions. A CCW heat exchanger is considered inoperable after its outlet valve is adjusted until a flow verification test is performed. The flow verification test requires that the system alignment with the most system resistance i.e.,

ASW pump #1 to CCW heat exchanger #2 (or ASW pump #f2 to CCW heat exchanger #1) be used. This realignment, test and subsequent data analysis takes several hours, during which time the CCW heat exchanger is inoperable. Diablo Canyon Technical Specifications require that the second vital CCW heat exchanger be placed in service whenever ultimate heat sink temperature is greater than 640F. In order to meet the Technical Specification LCO, ASW pump tests performed when ultimate heat sink temperatures are above 641F must be performed with two CCW heat exchangers in service and result in test flows of up to 14,000 gpm. When the test is run with only one CCW heat exchanger in service (normal test alignment),

reference pump flow is between 11,500 and 12,500 gpm. Relief is requested per 10CFR50.55a(f) (5) (iii).
