Attachment A.1 Page 1 of 2 EXCEPTIONS An exception is required to IWP-4210. Gage lines have not been provided with a suitable means to assure or determine the presence or absence of liquid when that presence or absence could produce a difference of more than 0.25% in the indicated value of the measured pressure. Reference values and subsequent test values will all be taken with the gage lines as designed. Therefore, any error vould be common to all values recorded and not affect the evaluation of the data.
An exception is required to IWP-4110.
Instrumentation included under this exception is only + 4% accurate.
1.
The accuracy of flow instrumentation at normal operating flows is about
+ 8%.
This accuracy does not lend itself to satisfying the requirements of Table IWP-2100-2 where the acceptable range is +2% -6%.
In addition, varying flow rates interferes with normal plant operation since flows h;ve been balanced to meet heat load requirements. Therefore, the AP and Q f;r each of these cumps will be recorded but not compared to reference valuen ror head curve verifica-tion. Additionally, motor current will be recorded for comparison purposes.
2.
Suction pressure instrumentation is not installed nor required. These pumps are capable of producing greater than 2400 psig discharge pressure, while the suction pressure would nominally be 15 to 20 psig.
The Volume Control Tank pressure will be recorded using Control Room indication to establish initial conditions for testing.
This indication is about 4% accurate.
3.
Monitoring discharge pressure monthly is considered sufficient since these pumps provide the driving force to deliver boric acid to the charging pump suction and operator observation of boration and chemical analysis of boron concentration will indicate whether desired results have been achieved.
The Boric Acid Tanks serve as the head for these pumps. Tank level will be observed from the Control Room to establish initial conditions for testing.
This indi-cation is about 4% accurate. The pump is totally encased in insulation making Tb, V and Lubricant level or pressure impossible to measure or observe.
4.
This pump takes suction from Lake Anna. The reservoir has a minimum level required by Technical Specifications.
This indication which is about 4% accurate, will be observed from the Control Room to establish initial conditions for testing.
Proper lubricant pressure or level cannot be observed since the bearings are in the main flow path.
Attachment A.1 Page 2 of 2 5.
In accordance with Technical Specification 4.7.9.1, measured quantities will be obtained at least every 18 months.
These pu.nps are not Engineered Safety Features pumps.
Operability during extended use can be determined by monitoring reactor coolant system temperature.
Due to location of Pi instrumentation, meaningful data can only be obtained with the pump in operation.
6.
These pumps are run dry to verify operaticul readiness; therefore, Pi, AP, Q and Proper Lubricant Level or Pressure cannot be measured.
Each pump is equipped with a sensor to detect pump rotation.
In addition, a vibration alarm associated with each pump will alert Control Room personnel to excessive pump vibration.
7.
These pumps will be run dry or wet to verify operational readiness.
Each will be observed to verify rotation. At least once per 18 months, each will be tested on its recirculation path when flow and discharge pressure will be observed. A vibration alarm associated with each pump will alert Control Room personnel to excessive pump vibration.
Due to pump design, it is not possible to measure a suction pressure.
Proper lubricant level or pressure is not required since bearings are in the main flow path.
8.
These pumps take suction from the RWST for pump performance testing.
This tank has a minimum level required by Technical Specifications, which will be observed from the Control Room. This indication is about 4% accurate.
Proper lubricant level or pressure cannot be observed since bearings are in the main ficw path.
9.
The accuracy of flow instrumentation at normal operatin] flows is about
+ 8%.
This accuracy does not lend itself to satisfying the requirements of Table IWP-2100 2 where the acceptable range is +2% -6%.
In addition, varying flow rates interferes with normal plant operation since flows have been balanced to meet heat load requirements. Therefore, the discharge pressure and Q for each pump will be recorded but not compared to reference values for head curve verification.
Thase pumps take suction from the Service Water Reservoir, which has a minimum level required by Technical Specifications.
This level indication, which is about 4% accurate, will be observed from the Control Room to establish initial conditions for testing.
Proper lubricant level or pressure cannot be observed since bearings are in the main flow path. Motor current will be recorded for comparison purposes.
10.
This pumn takes suction from the Service Water Reservoir, which has a minimum required level by Technical Specifications.
This level indication, which is about 4% accurate, will be observed from the Control Room to establish initial conditions for testings.
Proper lubricant level or pressure cannot be c5 served since bearings are in the main flow path.
11.
The flow paths of these pumps are normally dry. Atleast once per 18 month, each pump will be automatically started in conjunction with a test signal for Containment Depressurization Actuation.
12.
The bearing lubrication for these pumps is grease instead of oil.
The grease will be checked annually.
Attachment A.2 Page 1 of 1 NOTES Note 1 In a fixed resistance system, it is required to measure AP or 0, not both (IWP Table 3100-1).
Note 2 When these pumps are operated on recirculation flow, the system is fixed resistance.
When they are tested as the operating pump, the system is variable resistance.
Note 3 Reference is made to IWP 4310 which establishes exception to Tb for bearings within the main flow path.
Note 4 Pump will be tested only when there is water in the spent fuel pit.

ATTACHMENT B REQUESTED EXCEPTIONS TO THE INSERVICE TESTING REQUIREMENTS FOR VALVES AS SET FORTH IN SUBSECTION IWV TO SECTION XI 0F THE ASME CODE 1974 EDITION WITH ADDENDA THROUGH SUMMER 1975 NORTH ANNA UNIT 2
Attachment B.O Page 1 of 2 STATEMENT OF PARTICULARS A review of ASME class 1, 2, 3 valves has been completed for the North Anna Unit 2 Systems.
Attachment B.1 provides a tabulation of the valves that are subject to the testing requirements of ASME Boiler and Pressure Vessel Coc, 1974 edition, subsection IWV with addenda through summer 1975.
e The tab.e identifies the valves to be tested, valve code classes, and valve category per IWV-2000. Relief from the testing requirements of ASME XI is requested when they are determined to be impractical.
Specific information regarding the code requirement determined to be impractical and alternate testing programs are noted in Attachment B.2.
Leak testing of containment isolation valves shall be performed in accordance with Appendix J of 10CFR50 in lieu of ASME XI subsection IWV.
There are n-testable Category D valves in North Anna Unit 2 Systems.
A.t Category E vat.cs shall be tested in accordance with IWV-3700.
Any inspection requirements identified as impractical during the course of the inspection period will be noted and includ ?
cne inspection program at the time of the next revision.
When one valve in a redundant safety related system is found inoperable during testing, non-redundant valves in the remaining train will not be cycled as procedures require but will be cycled af ter the first inoperable valve in the system is returned to service.
This valve testing program addresses all valves determined to be essential in the mitigation of the consequences of an accident. The program has been reviewed to assure that testing the valves at the intervals speci-fied will not plant in an unsafe condition. Where practical, valves will be cycled at 3 month test intervals.

Attachment B.2 Page 1 of 3 NOTES 1.
Closing of these valves during pow-r operations would seriously impair the heat removal capability of the containment ventilation system.
These valves are vital for continued power operations. As an alternative, they will be cycled each cold shutdown.
2.
Component cooling water flow to the reactor coolant pumps is required 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 each refueling when the reactor coolant pumps are inoperative.
Verification of check valve operation to the open position will be performed each time coolant flow is re-established after each refueling.
3.
The frequency and qunatity of relief valves subject to test at each refueling outage will be in accordance with IWV-3500.
4.
Check valves remain in a normally open position with component cooling flow to the heat exchangers. Verification that check valves re-open will be obtained when flow is interrupted and re-established for the cycling tests of the associated power operated valves.
5.
Exercising this valve during power operation would require the charging pump suctions to be aligned with the refueling water storage tank.
This would cause a sudden increase in RCS boron inventory.
It will be exercised during cold shutdown when the RCS is borated to shutdown conditions.
6.
Failure of these valves in a closed position during exercising would cause a loss of charging flow and could result in an inability to maintain reactor coolant inventory. There valves will be exercised when the charging system is not in use during a refueling shutdown.
7.
Exercising this valve during operation could cause a sudden increase in RCS boron inventory.
It shall be exercised at cold shutdown when the RCS is already borated to shutdown conditions.
8.
To protect pump seals, flow to them is required at all times during power operation or cold shutdown.
Exercising of these valves will be performed during refueling outages when risk of equipment damage is eliminated by securing the pumps.
9.
This valve'cannot be exercised when the charging and 'etdown systems are in operation due to the high risk of overpressurization of the RCS.
It will be exercised at refueling outages when the charging and letdown systems are secured.
- 10. These valves are in the position required to fulfill their function.
Exercising this valve will not improve its operational readiness.
Exercising this valve may actually decrease system reliability if the valve fails in a nonconservative position. As an alternate, it will be exercised at refueling outages.
Attachment B.2 Page 2 of
- 11. Closure of mainsteam or feedwater valves during normal operations would result in turbine and reactor trips. These valves are closed during the process of shutdown and reopened during plant start-up.
Operation of these valves will be verified at each refueling.
- 12. Opening of these valves during power operations would introduce cold Auxiliary Feedwater to the Steam Generators resulting in possible thermal stress.
As an alternative, these valves will be checked each re fue ling.
- 13. Closure of these valves during power operation will result in a Reactor Trip. As an alternative, they will be cycled each reactor shutdown, but not more than once every 92 days.
- 14. It is not possible to verify that this normally closed check valve opens without initiation of spray through the upper containment header or by visual observation inside the containment. This valve shall be exercised during refueling outages.
- 15. It is impractical to exercise this check valve during power coeration per IWV-3520. Opening the test valve would break containment vacuum.
The check valves shall be exercised at refueling outages.
- 16. Operation of RHR System Valves during power cperations would subject the RHR System to full RCS pressure. Valves in the RHR system will be exercised each time tne RHR system is put into operation during the cooldown and shutdown of the reactor coolant system.
- 17. Opening their valves during power operation would break containment vacuum and violate containment integrity. Their valves shall be exer-cised each cold shutdown, but not more than once every 92 days.
- 18. These normally closed valves are directly attached to the charging pump discharge header.
During operation or cold shutdown the charging system must be in operation.
If these valves were opened during these periods, uncontrolled flow to the reactor coolant system may cause overpressuriza-tion.
As an alternate, these valves shall be cycled at refueling outages.
- 19. These normally opened valves are in the required position for an accident and are required by Technical Specifications to remain open during power operations.
They are closed in the normal process of shutdown to cold conditions and reopened during subsequent heat up.
- 20. These valves are required to be open with power to t..eir operators removed during power operations. As an alternative, they will be cycled every cold shutdown, but not more than once per 92 days.
- 21. These normally closed check valves cannot be exercised during plant operation or cold shutdown.
No connections exist downstream of the check valve to input flow or pressure which could promote movement of the disc away from the seat.
A test connection is required between the isolation valve and the check valves but cannot be installed.
Attachment ".2 Page 3 of 3 The isolation valve and check valve are butt welded together with no spool piece between them to provide a place for the test connection. As an alternate test, the check valve bonnet shall be removed at refueling outages and the disc shall be exercised mechanically to verify free movement without binding.
- 22. The only way to verify that these normally closed check valves open is by initiating flow, using the charging pumps, into the reactor coolant system hot and cold legs.
If charging flow was directed to the reactor coolant system in this manner it could cause overpressurization during cold shutdown or provide a loss in charging flow control during operation.
As an alternate, these check valves shall be exercised open during refueling outages.
- 23. The only way to verify that these normally closed check valves can open is by initiating flow, using the low head safety injection pumps, into the reactor coolant system hot andd cold legs.
During operation or cold shutdown reactor coolant system pressure will be higher than the low head pump discharge pressure precluding flow into the vessel. As an alternate, these valves shall be exercised open at refueling outages.
- 24. This valve cannot be exercised without possible damage to the charging pumps. It will be exercised with the charging pumps secured at re fue ling outages.
- 25. To exercise this normally closed check valve would require the simulation of a loss of coolant accident, i.e.
Icw RCS pressure. The valve shall be verified operable by initiating accumulator inje<. tion to the RCS with the vessel head removed during each refueling outag e.
- 26. A commitment has been made to th ACRS prohibiting :he introduction of service water into the Recird. Spray Heat Ezchanger3 without subsequent drying by a compressed air purge through the heat exchanger.
Exercising this valve will be accomplished at refueling outages when service water flow will be sent through t'a heat exchangers and iir drying may be accomplished.
