POWER AUTHORITY STATE OF NEW YORK INDIAN POINT UNIT 3 SECOND 40 MONTH PERIOD OF FIRST 10 YEAR INTERVAL The attached tables provide a listing Of the Class 1, 2 and 3 pressure-retaining components (and their supports) which are subject to the inspection requirements of Subsections IWB, IWC and IWD of Section XI of the ASME Boiler and Pressure Vessel Code, 1974 Edition, and Addenda through Summier, 1975.
These tabulations identify the components to be inspected, the components safety class, the applicable code to which the component was built, and the method of examination.
Relief from the inspection requirements of each Subsection is requested in cases where these inspection requirements have been determined to be impractical.
Where relief is requested, specific information is provided which identifies the applicable code requirement, justification for the relief request, and the inspection method to be used as an alternative.
The following pro vide further clarification concerning the Class 1, 2 and 3 system inspection programs.
(a) Articles IWC-3000 and IWD-3000 entitled, "Evaluation of Examination Results" are in the course of preparation by the Code Commnittee and, as yet, are not available for use. Standards for examination evaluations as included in the 1974 Edition of Section XI with Addenda through the Sumrier, 1975, are incomplete and "Acceptance Standards for Flaw Indications "as given in Article IWB-3000 of the 1977 Edition of Section XI will be utilized.
(b) Articles IWC-4000 and IWD-4000 entitled, "Repair Procedures" state that the rules of IWB-4000 shall apply. When the repair procedures outlined in IWB-4000 are not applicable for the Class 2 and 3 components in this program, the rules of IWA-4000 will be applied.
'(c) Requirements for the visual examination of Class 1 systems and components for evidence of leakage during the performance of a system pressure test following each refueling are identified by
IWB-5200. Exception is taken to the implementation of these requirements on those portions of Class 1 systems which are contained between two check valves or two normally closed valves, where pressure applied to the reactor coolant system will'be retained at the first valve in the line. The portions of systems affected by this limitation are:
(1) Cold leg injection from accumulators between check valves 897A, B, C and D and 895A, B, C and D, test lines to valves 839A, B, C and D, RHR return and low head injection lines to valves 838A, B, C and D and high head injection lines to valves 857A, Q9-S and U. During normal operation these portions of the systems are filled and pressurized to the normal accumulator operating pressure of 620 to 665 psig.
(II) Hot leg injection between check valves 857C, D, E and F and check valves 857J, K, L and M. These portions of systems are filled and vented but not pressurized during normal operation.
(III) Cold leg boron injection line between check valves 857C, D, E and F and check valves 857J, K, L and M.
(IV) RHR take off line between normally closed (with pressure interlock) valves 730 and 731.
This portion of the system will-be pressurized whenever the system is put into operation during plant shutdown when the reactor coolant system is cooled to 350'F and depressurized to 450 psig.
These valves are interlocked to automatically isolate when the reactor coolant system pressure exceeds 600 psig.
(d Subsections IWB and IWC contain differing requirements for the hydrostatic testing of Class 1 and Class 2 systems and components.
The implementation of these requirements is impractical when the only means of pressurizing the Class 2 system is through the Class 1 system or when the boundary between the two systems 1s a check valve arranged for flow from Class 2 to the Class 1 system.
Exception is taken to the performance of the hydrostatic test requirements as required by Article IWC-2412 (a) on those portions of the Class 2 systems identified below. Visual examination for evidence of leakage will be conducted on these portions of the systems at the system nominal operating pressure in accordance with the requirements of IWB-5221 for the adjoining Class 1 system.
(I) Pressurizer steam space sampling line from valve 950 to valve 956 A, pressurizer liquid space sampling line from valve 952 to valve 956 C and loop sampling lines to valve 956E.
(e) The examination requirements for Class 3 systems and components as given in the attached tabulation are in accordance with IWD 2410(c) which specifies that 100 percent of the components be examined as required by IWS-5240 and IWD-2600 either during normal operation or during system inservice testing. An additional requirement of IWD-2410(b) is for the examination of Class 3 systems and components for evidence of leakage during the per formance of a system pressure test in accordance with IWD-5000.
The Code does not stipulate that certain amounts of these exam ination requirements be completed within each 40 month period such that the system pressure test requirements may be deferred until the end of the ten year inspection interval.
However, it should be noted, that these system pressure tests when required are impractical in those systems, such as component cooling, river water, spent fuel pit cooling, and boric acid transfer and recirculation, which are in continuous operation during all modes of plant operation. The continuous functional operatton serves to demonstrate the structural and leak-tight integrity of these systems. Visual examinations of these systems will be performed at normal operation pressures to verify leak-tightness, (f) Ultrasonic examinations will be conducted in accordance with the provisions of Appendix 1 and Article 5 of Section V as required
by paragraph IWA-2232.
As an alternative to using Article 5 of Section V, Appendix III of Section XI of the 1974 Edition, Winter, 1975 Addenda of the ASME Boiler and Pressure Vessel Code will be used for ultrasonic examination of piping systems.
It is recognized that Appendix III of Section XI was issued in the Winter, 1975, Addenda and, as such, has not been officially recognized by the NRC by reference in 10 CFR 50. However, Appendix III is the first guideline that has been published in the ASME Codes for the ultrasonic examination of pipe welds and, as such, its use is essential.
The extent and frequency of examination of Class 1 and 2 piping system welds will be as required by Table IWB-2500 Category B-J and Table IWC-2520 Categories C-F and C-G. However, examination requirements and examination methods for piping system welds will be as defined in Tables IWB-2500-1 Category B-J and IWC-2500 1 Category C-F of the 1977 Edition of Section XI Summer 1978 Addenda.
(g) As an alternative for 1-3121 of Section XI:
"Calibration blocks required for the examination of welds in ferritic vessels 2 1/2 inches thick and over will be fabricated from material of the same specification, product form, and heat treatment as one of the materials being joined as allowed by article T-434.1 in the Winter, 1976 Addenda of Section V of the ASME Boiler and Pressure Vessel Code."
The reason this al.ternative is requested is that the Code requires that calibration blocks for the examination of welds in ferritic vessels 2 1/2 inches thick and greater be fabricated from material taken from the component nozzle drop out or material from the component, the block may be fabricated from a material of a specification included in the applicable examination volumes of the component. It is required that the acoustic velocity and attenuation of such a block be demonstrated to fall within-the range of straight beam longitudinal wave velocity and attenuation found in the unclad components.
For the components in the Indian Point Unit 3 Plant, particularly the pressurizer and steam generators, it will be impossible to meet the requirements of alternative 1 or 2. Materials of the specification are readily available, but because all the components involved are clad on the inner surfaces, it would be impossible to obtain a comparison of sound beam velocities and attenuations in the unclad component.
Table IWB-2600 contains requirements for the examination of vessel cladding on thereactor vessel closure head (Item Bl.13),
the reactor vessel (Item Bl.14) the pressurizer (Item B2.9) and the steam generator primary side (Item B3.8).
Volumetric examinations performed on each of these vessels for the inspection of welds will detect defects which may originate in the clad material and extend into the base material for more readily than visual examinations of the clad surface. As this examination requirement is deleted by later editions of the code, exception is taken to the performance of these examinations.
Limitations may occur for the examination of piping system circum ferential butt welds (Category B-J) when the welds occur at geometric discontinuities such as pipe to vessel welds, pipe to fitting welds or fitting to fitting welds. For pipe to fitting or pipe to vessel nozzle welds, examinations can be performed to the extent required by T-532 of Section V from the weld and pipe surfaces. Examination from the fitting side would be dependent upon the geometrlc con figuration. Where elbows or tees are concerned, examination can be performed from the fitting side except where the intrados of
the fitting prevents adequate ultrasonic coupling. No examinations can be performed from the fitting side when it is a valve or a flange. In all cases 100 percent of the weld material can be examined.
In instances where welds occur at fitting to fi-tting, access restrictions as outlined above occur on both sides of the weld.
In instances where ultrasonic examinations cannot be per formed on 100 percent of the volume of the weld and heat affected zone, surface examinations will be performed to supplement the limited volumetric examination.
Welds in the Indian Point Unit #3, Class 1 system which due to limitations, would require surface examinations are:

Certain Class 2 systems or portions of Class 2 systems and components are exempt from the examination requirements of the IWC-2520 by IWC 1220. A summnary of these exemptions as applicable to the Indian Point
plant systems are as follows:
(I)
During plant operation, the boric acid solution will be constantly recirculated through the boron injectiorf-tank by the recirculation pump system. Samples would normally be taken on a regular basis and the component and associated piping would be exempt from examination by IWC-1220(c).
(II) The boron injection tank discharge piping is all equal to or less than 4 inch nominal diameter.
(III)
During plant operation, the contents of the SIS accumulators are normally sampled on a regular basis and this component and associated piping would also be exempted by IWC-1220(c).
(IV) During plant operation, the high head SIS injection pumps are run on a periodic basis to recirculate flow to and from the RWST. Samples taken on a regular basis from the RWST would verify the chemistry of the system fluid and exemption from examination would again be by IWC-1220(c).
V)
The high head SlS piping equal to or less than 4-inch nominal diameter is exempted by INC-1220(d).
(VI)
The containment spray system and recirculation spray systems do not function during normal reactor operation and exempted by IWC-1220(b).
(VII) The RWST and associated piping have design pressures and temperatures less than 275 psig and 200°F and are exempt by IWC-1220(a).
The inservlce inspection programs outlined in the attached tabulations have been developed as a result of a design review. Should certain ASME Section XI Code requirements be discovered to be impractical due to unforeseen reasons during the process of performing inspections or tests, relief will be requested from the specific Section XI Code requirement at that time.
Radiation levels in certain areas or of certain components may be found to prohibit the access for operators or inspectors to perform the inspections or tests described in this program. If source strengths cannot be reduced and access is still restricted by considerations of compliance with the require ments of Regulatory Guides 8.8 and 8.10, relief will be requested from the 1pecific Section XI Code requirements and alternative examination or test requirements be proposed.

ASME CODE CLASS 1 COMPONENTS NOTES
- 1. The examination of these welds as required by IWB-2600 from inside the vessel is restricted by the locations of the adjacent incore instrumentation penetrations.
Examination of those areas accessi ble between the penetrations and conduits may be performed from the outside surface to the extent practical due to radiation levels. Examinations will not be performed if the examiners must receive a whole body dose in excess of 1250 mrem in order to complete any one examination. Examinations will be performed on five percent or ten percent of the total length of each weld as required by the Code. Examination of these welds will be performed at or near the end of the ten-year interval as allowed by the Code.
- 2. The closure head disc to peel segment weld is completely enclosed within the pattern of CRDM penetrations inside the shroud and is not accessible for examination as required by IWB-2600. This area will be subject to visual examination for evidence of leakage during the performance of system hydrostatic tests.
- 3. Limited access to the O.D. of these welds is provided by removable plugs in the primary shield above the nozzles and removable insulation covering the nozzle welds. Exception is taken to performing a surface examination on these welds due to anticipated radiation levels and physical access.
- 4. The Reactor Vessel Closure head studs are removed during each refueling and there will be no for examination in place as required by IWB-2600.
- 5. The reactor vessel is supported in pads integral with the inlet and outlet nozzles and therefore are excluded from examination requirements of IWB-2500 by category B-H.
- 6. Radiation levels beneath the closure head may affect the allowable exposure dosage of personnel doing surface and visual examinations.
The presence of the cladding material is not considered when performing the stress analysis of the Vessel such that failure of the cladding would not affect the integrity of the vessel.
The closure head cladding will be volumetrically examined concurrent with the examinations performed on the closure head to flange weld.
- 7. This requirement is applicable only to Boiling water type Reactors.
- 8. Six Circumferential welds and five longitudinal welds on the pressurizer are enclosed in a biolo gical and missle shield and therefore are not accessible for examination.
- 9. The pressurizer nozzles are cast with the upper and lower heads, therefore there are no welds re quiring examination in accordance with the requirement of IWB-2600.
- 10. There are no items in this category on this component in the Indian Point Unit #3 Class systems.
- 11.
The steam generator nozzles are cast with the primary head therefore there are no welds requiring examination in accordance with the requirement of IWB-2600.
- 12.
Examination of the steam generator primary nozzle to safe-end and safe-end to pipe weld is limited both by the nozzle geometry and surface condition and the limited surface preparation on the pipe side of the weld. The surface on the pipe side of the weld, which is a cast elbow, is machined for a distance of approximately three inches from the edge of the weld. Ultrasonic examination is limited to this from the edge of the weld. Examinations can be performed on the surface of the weld but are severly limited from the nozzle side by the rough, as cast surface. Surface examination can be performed on one hundred percent of the weld and the base metal on the pipe side. The con figuration is shown in figure 1.
- 13. Limitations may occur from the examination of piping system circumferential butt welds (Category B-J) when the welds occur at geometric discontinuities such as pipe to vessel welds, pipe to fitting welds or fitting to fitting welds. For pipe to fitting or pipe to vessel nozzle welds, examinations can be performed to the extent required by T-532 of Section V from the weld and pipe surfaces. Examination from the fitting side would be dependent upon the geometric configuration. Where elbows or tees are, concerned, examinations can be performed from the fitting side except where the intrados of the fitting prevents adequate ultrasonic coupling. No examinations can be performed from the fitting side when it is a valve or a flange. In all cases one hundred percent of the weld material can be examined.
In-instances where welds occur at fitting to fitting, access restrictions as outlined abo~q occur on both sides of the welds. In instances where ultrasonic examinations cannot be performed on one hun dred percent of the volume of the weld and heat affected zone, surface examinations will be performed to supplement the limited volumetric examination.
- 14. The ninety degree elbows on the crossover leg of the reactor coolant system are fabricated in two halves from austenitic stainless steel castings welded together by the electroslag process. The structure and nature of the electroslag weld in the cast austenitic ninety degree elbows is such that the material is opaque to ultrasonic transmissions utilizing currently available techniques.
Radiography is the only other available technique for volumetric examination.It is not possible to obtain code acceptable radiographs with double wall "shots" on these components which are approximately thirty-eight inches diameter, 3.5 inches wall thickness, containing a two inch thick splitter plate and having radiation levels of up to 300 mr/hr on contact. Surface examina tion could be performed on these welds.
- 15. The configuration of the reactor coolant branch nozzle connection welds is as shown in figure 2.
Ultrasonic examinations cannot be performed on the surface of the weld. Examinations will be per formed to the extent practical from the pipe and nozzle surfaces adjacent to the weld. Surface examinations will be performed to supplement the volumetric examination.
- 16. The piping system integrally welded supports are attached to the pipe by fillet welds. The con figuration of such welds is such that examinations cannot be performed to the extent required by IWB-2600 and only the base material of the pipe wall can be examined by ultrasonic technique.
Surface examinations will be performed on the integrally welded attachments to supplement the limited volumetric examinations.
- 17. The reactor coolant pump main flange bolting is ultrasonically examined in place in accordance with the requirements of IWB-2600, Item B5.1. The main flange bolting will be examined as required by IWB-2600, Item B5.2 whenever a pump is disassembled for maintenance or at the end of the ten year interval when a pump will be disassembled for the performance of examinations required by Category B-L-l.
- 18.
The structure and nature of the material of integrally welded pump supports is such that it is opaque to ultrasonic transmission. Surface and visual examination will be performed as a sub stitute for volumetric.
- 19. the reactor coolant pumps casing in the Indian Point Unit #3 plant is a weldment of two cast shells.
The structure and nature of this material is such that it is opaque to ultrasonic transmission.
However the accessible internal surfaces shall be visually and liquid penetrant inspected. Volu metric examinations as required by IWB-2600 can be attempted utilizing radiographic techniques.
Thd success of these examinations (radiographs) will be dependent upon the availability of'.high energy gamma sources and the level of background radi 'ation. Internal fittings on the pump may also provide restriction to the extent if examination that can be performed.

ASME CODE CLASS 2 COMPONENTS NOTES
- 1. There are no items in this category for this component of the Indian Point Unit #3 Nuclear Power Plant.
- 2. The nozzle to vessel welds of the Residual Heat Exchangers are covered by.75" thick by 3" wide re inforcement pads as shown in figure 3. These welds are not accessible for examination by Volumetric or surface methods. The area will be subject to visual examination for evidence of leakage during system pressure tests.
- 3. Examination of Class 2 piping systems is limited by those occuring at geometric discontinuities such that some limitations may be expected at all locations.
For pipe to fitting or pipe to vessel nozzle welds, examinations can be performed to the extent required by T-532 of Section V from the weld and pipe surfaces. Examination from the fitting side would be dependent upon the geometric configuration.
,.Where elbows or tees are concerned, examinations can be performed from the fitting side except where the introdos of the fitting prevents adequate ultrasonic coupling. No examinations can be performed from the fitting side when it is a valve or a flange. In all cases one hundred percent of the weld material can be examined. In instances where welds o
'ccur at fitting to fitting, access restrictions
.as outlined above occur on both sides of the weld. In instances where ultrasonic examinations cannot
- be performed on one hundred percent of the volume of the weld and heat effected zone, surface exam ination will be performed to supplement the limited volumetric examination.
- 4. The configuration of typical branch pipe to pipe welds is as shown In figure 4. Ultrasonic examination cannot be performed on the surface of the weld.
Examinations will be performed to the extent practical from the pipe and nozzle surfaces adjacent to the weld. Surface examination of the weld will be per formed to supplement the volumetric examination.

INSERVICE TESTING OF PUMPS PROGRAM NOTES
- 1. The system as designed and installed does not contain instrumentation for the measurement of pump inlet pressure.- Under the conditions that.....
the pump performance test will be carried out, with low flow conditions on recirculation "miniflow," the head losses in the inch diameter suction piping will be extremely small and inlet pressure can be taken from the head of water above the pump suction in the RWST.
- 2. Under the operating mode in which these pumps will be tested, the system will have fixed resistance. As allowed by footnote 1 of Table IWP-3100-1, this parameter will not be recorded.
- 3. There is no instrumentation to monitor this operating parameter in the plant system as designed and constructed.------
- 4. The service water pumps are vertical design with no means of direct inlet pressure measurement as required by IWP-4200. Inlet pressure to these pu.ps will be established by reference to the level of water above the pump suction. As the measurement of the level of water above suction is to be used to determine the inlet pressure, relief is required from meeting pressure tap construction and location requirements of IWP-4211 and IWP-4212.
- 5. Three pumps are in continuous operation for both the essential and non-essential loads during all modes of plant operation. The service load for these pumps constantly varies with plant power load, plant operating status, river water and ambient air temperatures and it is not possible to ensure that flow and head parameters will be the same at any two monthly performance tests.
Flow measurement instrumentation Is only installed in this system at the outlets from the containment ventilation coolers and flow measurements will be taken at this point.
- 6. The service water pumps are open line shaft pumps that depend primarily of the liquid being pumped for the lubrication of the pump and line shaft bearings. All pump bearings are submerged and lubricant is allowed to leak off into the sump and is not piped back, such that bearing or lubricatn outlet temperature cannot be monitored.
- 7. A minimum of two component cooling pumps are in continuouS-use during all modes of plant operation and as the service load for these pumps constantly varies with plant power load, plant operating status and water and ambient air temperatures, it is not possible to ensure that flow and head parameters will be the same at any two monthly performance tests or to measure these parameters for a Single operating pump.
- 8. Instrumentation is provided for monitoring temperature of the pump thrust bearing only. No temperature measuring devices are installed at the radial bearing.
- 9. The monthly performance test will generally be conducted with re circulation "mini-flow" conditions. Under these high head, low flow conditions the pumps are expected to vibrate considerably more than under full flow conditions. Accurate vibration readings will be taken each refueling outage when full system flow tests are run.
- 10.
Pump bearings are carried in the driver motor and are grease lubricated.
- 11.
When the pump is tested on recirculation flow, the flow path is a fixed resistance system and it is required to measure AP or Q, not both (Table IWP-3100-1). When the pump is tested during normal operation, the flow path is a variable resistance system and it is required to measure both AP and Q.
INDIAN POINT UNIT 3 INSERVICE TESTING OF VALVES The enclosed tabulation provides a listing of the Class 1, 2 and 3 valves which are subject to the testing requirements of Subsection IWV of Section XI of the ASME Boiler and Pressure Vessel Code, 1974 Edition, with Addenda thru the Summer of 1975.
This tabulation identifies the valve to be tested, drawing location, fun ction, code class, category, size, valve type, actuator type, normal position and test requirements. Relief from test requirements is requested in cases where these test requirements have been determined to be impractical.
Where relief is requested, technical justification is provided along with alter native test methods when applicable.
Leak testing of containment isolation valves shall be performed in accordance with Appendix J of IOCFR50 in lieu of ASME Section XI subsub-article IWV-3420.
A separate tabulation of containment isolation valves which are not included in the IWV Program is provided.
Any inspection requirements identified as impractical during the course of the inspection period will be noted and included in the inspection program at the time of the next revision.
When one valve in a redundant safety related system is found inoperable during testing, nonredundant valves in the remaining train will not be cycled as procedures required, but will be cycled after the first inoperable valve in the system is returned to service.
This valve testing program addresses those valves for which demonstration of operability is necessary to assure safe shutdown of the unit or mitigation of the consequences of an accident. The program has been re viewed to assure that testing the valves at the intervals specified will not place the plant in an unsafe condition. Where practical, valves will be cycled at 3 month test intervals.
When a commitment is made to test valves during hot or cold shutdown, it is not intent to shutdown the unit soley for the purpose of valve testing nor to perform the testing more often than once per 92 days due to more frequent shutdowns.
The following clarification shall apply to those valves which are scheduled to be exercised during cold shutdown:
"Valve testing shall commence not later than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after reaching cold shutdown and continue until complete or unit is ready to return to power. Completion of all valve test i'ng is not a prerequisite to return to power."
Article IWV-3520(b) requires that check valves be exercised to the position required to fulfill their function. Check valves in the Indian Point plant systems are not equipped with position indicating devices and verification of operation to the required position will be achieved by observing that
.....normal required flows are established in the systems.
The stroke times of solenoid controlled, air operated valves is both extremely rapid and subject to considerable variation. Exception is taken to complying with stroke time variations defined by Article IWV-3410(c)(3).
LEGEND TEST REQUIREMENTS SP -

INDIAN POINT UNIT 3 INSERVICE TESTING OF VALVES PROGRAM NOTES
- 1. Closure of mainsteam stop valves during normal operation would result in turbine and reactor trips. These valves are fully stroked to a closed position each time the plant goes to a cold shutdown condition and are re-opened again on plant startup.
- 2. Verification that check valves open as required will be observed when pump discharge flow is established during the conduct of monthly performance test required by IWP.
- 3. Closure of main feedwater stop valves during normal operation would result in a reactor trip. These valves are fully stroked to a closed position each time the plant goes to a cold shutdown condition and are reopened again on plant startup.
- 4. Operation of valves in the auxiliary steam and feedwater systems will be verified when the pump is operated flow during a monthly performance test. Operation of these valves will also be verified at each cold shutdown. During plant start-up and shutdown, steam generator feed is provided by the auxiliary feedwater system and operation of the check valves in the auxiliary feedwater lines will be verified at cold shutdown when flow is established.
- 5. A minimum of two service water pumps are in use during all modes of plant operation and check valves in the pump discharge would remain passively open. Verification that the check valve opens and normal flow is established will be achieved whenever an inactive pump is put into operation for periodic performance testing as required by IWP.
- 6. Operation of this normally closed check valve will be verified each refueling outage. Operation will be verified by initiating and
observing that flow is established through the systepj, Partfl stroking of these check valves could only be achieved by intro ducing safety injection flow into the RCS.
Paragraph IWV-341OCb) requires that normally closed valves that cannot be operated during normal plant operation shall be specifically identified and shall be full-stroke exercised during each cold shutdown. Certain Valves subject to this limitation have been identified in the table as being exercised at each refueling outage. The term "cold shut down" covers a wide variety of plant conditions which can exist with the reactor coolant temperature equal to, or less than, 200*F.
Under cold shutdown conditions, the system may be "solid" such that introducing flow into the system to exercise check valves would have a high probability of overpressurizing the system.
These tests can only be performed when the reactor coolant system is vented to the containment atmosphere and partially drained as for a refueling outage or for maintenance requiring access into the reactor coolant system.
- 7. Failure of these valves in an open position would result in the loss of availability of the RHR system for its function of cooling down the reactor system. Valves associated with the RHR system not in operation will be exercised during cold shutdown.
- 8. Valves in the RHR system will be exercised each time the system is put into operation during the cooldown and shutdown of the reactor coolant system. The RHR system is put into operation as a standard operating procedure whenever the reactor coolant temperature is to to reduced below 350°F and the pressure is below 400 psig.
- 9. Verification that check valves open as required will be observed when pump discharge flow is established during the conduct of the performance test required by IWP at each refueling outage.
- 10. This check valve will be partially.stroked during each monthly pump performance test. The valve will be full stroked during the
full system test at each refueling.
- 11.
The check valve will be partially stroked during each monthly pump performance test.
Full flow tests cannot be accomplished without fluid being sprayed into the containment.
- 12. Prior to exercising these valves, the locked open, manually operated diaphragm valve 1841 at the outlet of the spray additive tanks must be closed and the line flushed with water to prevent corrosive spray additive being introduced into the system when valves 876A or B are opened. This test will be performed at each refueling outage.
- 13. Verification that these check valves open as required will require that the locked closed, manually operated valve 873B, be opened to provide a fluid flow path for testing. This test will be carried out at each refueling outage.
- 14. Valve is normally open with power removed during normal operation.
Power will be restored and valve operability checked at each cold shutdown.
1'5.
The check valve in the discharge line of the operating component cooling pump or the auxiliary component cooling pump will remain passively open during plant operation. Verification that check valves open and normal flow is established will be achieved when ever an inactive pump is put into operation for plant service or for the periodic performance test required by IWP.
- 16. This check valve is passively open with continuous flow through the system. Verification that this valve remains In the open position as required for the fulfillment of its safety function will be achieved by monitoring system flow.
- 17. Auxiliary cooling water flow to the reactor coolant pumps is re quired at all times the pumps are in operation. Failure of one
of these valves in a closed position during cycling would result in a loss of the cooling flow to the pump. Power operated valves in these systems will be cycled at cold shutdowns when the reactor coolant pumps are inoperative.
- 18. This is a manually operated valve which remains in an open position during normal plant operation and is required to remain open for service water supply to the reactor containment ventilation coolers or recirculation pumps to mitigate the consequences of an accident.
The system is missile protected and designed to remain intact under post LOCA conditions and, in effect, is an extension of the con tainment. Valves will be exercised when closed for leak testing.
