Attachment A.1 Page 1 of 2 REMARKS An exception is required to IWP-4210. Gauge lines have not been provided with a suitable means to assure or determine the presence or absence of liquid when the 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 gauge lines as designed. Therefore, any error would 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 require-ments of Table IWP-2100-2 where the acceptable range is + 2% - 6%.
In addition, var 'ing flow rates interfere with normal plant operation since flows have L a balanced to meet heat load requirements. Therefore, the AP and Q for each of these pumps will be recorded but not compared to reference values for head curve verification. Additionally, motor current
)--
will be recorded for comparison purposes.
2.
Suction pressure instrumentation is not installed or 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 obeserved from the Control Room to establish initial conditions for testing.
The AP will be calculated fro'm the Boric Acid Tank level. This indication 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.

These pumps are run dry to verify operational 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.
6.
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 r.re in the main flow path.
7.
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 flow path.
8.
The accuracy of flow instrumentation at normal operating flow is about + 8%. This accuracy does not lend itself to satisfying the require-ments if Table IWP-2100-2 where the acceptable range is + 2% - 6%.
In 3
addition, varying flow rates interfere with normal plant operation since flows have been balanced to meet heat load requirements. Therefore, the dischage pressure and Q for each pump will be recorded but not compared to reference values for head curve verification. These 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.
9.
This pump 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 testing. Proper lubricant level or pressure cannot be observed since bearings are in the main flow path.
- 10. The flow paths of these pumps are normally dry. At least once per 18 months, each pump will be automatically started in conjunction with a test signal for Containment Depressurization Actuation. These pumps will be run dry monthly.
- 11. The bearing lubrication for these pumps is grease instead of oil. The grease' will be checked annually.

In a fixed resistance system, it is required to measure AP or Q, not both (IWP Table 3100-1).
9.
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.
3.
Reference is made to IWP 4310, which establishes exception to Tb for bearings within the main flow path.
4.
Pump will be tested only when there is water in the spent fuel pit.

,.0 Page 1 of 2 STATEMErlT 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 Code,1974 edition, subsection IWV with addenda through summer 1975. The table 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 regardir.g 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 perfonned in accordance wi+'
\\ppendix J of 10CFR50 in lieu of ASME XI subsection IWV.
There are no testable Category D valves in. North Anna Unit 2 Systems.
All Category E valves shall be tested in accordance with IWV-3700.
Any inspection requirements identified as impractical duri.ng 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, non-redundant valves in the remaining train will not be cycled as procedures require but will be cycled after 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 testi.ng 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.

Closing of these valves during power operations would seriously impair the heat removal capability of the containment ventilation system.
These valves are vital fo continued power operations.
As an alternative, they will be cycied 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 cold shutdown and refueling when the reactor coolant pumps are secured.
Verification of check valves operation to the open position will be perfonned each time cN1 ant flow is reestablished after each refueling.
3.
The frequency and quantity of relief valves subject to test at each refueling outage will be in accordance with IWV-3500.
RV-2203 will be exercised in accordance with the frequer.cy in IWV-3500.
4.
These check valves remain in a normally open position with component f
cooling flow. The only method for verifying these valves closed is during the refueling outage leak rate test.
5.
Exercising this valve during power operation would require the charg-ing pump suctions to be aligned with the refueling water storage tank. This would cause a sudden increase in RCS baron inventory.
It will be exercised during cold shutdown when the RCS is borated to shutdown conditions.
l 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. These valves will be exercised when the charging system is not iq use during cold shutdown and refueling outages.
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 f
power operation.
Exercising of these valves will be performed j
during cold shutdown and refueling octages tnen the risk of equip-ment damage is eliminated by securing the pumps.

V Attachment B.2 Page 2 of 5 9.
These valves cannot be exercised when the charging and letdown systems are in operation due to the high risk of overpressurization of the RCS. They will be exercised at co;d shutdown and refueling outages.
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 cold shutd:an and refueling outages.
11.
Closure of mainstream 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 when entering or leaving cold shutdown.
12.
2-FW-70, 2-FW-150, 2-FW-156, and 2-FW-279 cannot be exercised during cold shutdown, because steam is not available to operate the turbine driven auxiliary feedwater pump.
13.
Closure of these valves during power operation will result in a Reactor Trip. As an alternative, they will be cycled each cold shutdown, but not more than once every 92 days.
p 14.
It is not possible to verify that these normally closed check valves r
open without initiation of spray through the upper containment header or by visual obesrvation inside the containment. These valves shall be exercised during refueling outages as per the Technical Specification requirements for weight loaded check valves.
15.
It it impractical to exercise this check valve during power operation per IWV-3520. Opening the test valve would break conteinment vacuum.
The check valves shall be exercised at refueling outages.
16.
Operation of RHR System valves during power operations would subject the RHR System to full RCS pressura. Valves in the RHR System will be exercised each time the RHR System is put into operation during the cooldown and shutdown of the reactor coolant system. These valves will be leak tested in accordance with Technical Specifications.
17.
Opening their valves during power cperation would break containment vacuum and violate containment integrity. Their valves shall be exercised each cold shutdown, but not more than once every 92 days.
18.
These noramally closed valves are cirectly attached to the cha.rgi.ng pump discharge header. During operation or cold shutdown the charging system must be in operation.
If these valves were opened during these periods, uncontrolled ficw the the reactor coolant system may cause overpre c urization. As an alternate, these valves shall be cycled at refueling outages when the charging pumps can be secured.
Attachment B.2 Page 3 of 5
- 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 in their required safety position with power to their operators removed during power operations. To exercise these valves would require leakage testing as per T.S. 4.4.6.2.2.
The leakage testing would disturb the downstream check valves which would require a containment entry to test. As an alternate, these valves will be exercised each refueling.
- 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.
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 iaactor coolant system hot and cold legs.
If charging flow was directed to the reactor coolant system in this manner, it could I
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 hnt and 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 cold shutdown and refueling outages.
- 25. To' exercise this normally closed check valve would require the simula-tion of a loss of coolant accident, i.e. low RCS pressure. The valve shall be verified operable by initiating accumulator injection to the RCS with the vessel head removed during each refueling outage.
2-SI-170 and 2-SI-187 will be exercised when the RHR System is in service during cold shutdown.

- 26. A commitment has been made to the ACRS prohibiting the introduction of service water into the Recirc. Spray Heat Exchangers without subsequent filling of the heat 'xchanger with primary grade water.
Exercising this valve will be accomplished at refueling outages when service ' water flow will be sent though the heat exchangers and PG water may be used to fill them.
- 27. Valves FCV-2160 and 2-CH-332 cannot be exercised during power operation or cold shutdown.
FCV-2160 is normally closed and its accident posi-tion is closed (containment isolation function). The only method for verifying 2-CH-332 closed is during the refueling leak rate test.
- 28. These valves cannot be exercised during power operation or cold shutdown. The only method available to verify that these valves close is during the refueling leak rate test.
- 29. TV-CV-200 is normally closed and its accident position is closed.
The valve will be exercised during refueling outages when establishing containment vacuum.

- 30. These are manual valves and will not be exercised because they are in their accident position (closed).
31.
PCV-FW-259A, B will be exercised quarterly but will not.be timed.
Stroke time is not important because these are modulati.ng valves.
- 32. These valves will be tested during power operation. These valves i
cannot be tested during cold shutdown or refueling because steam is not available to run the turbine driven auxiliary feedwater pump.
- 33. This is the governor valve for the steam driven auxiliary feed i
pump. This valve is normally open and will be exercised but not timed every 18 months during the overspeed trip test.
34.
2-MS-19, 58 and 96 are located in a high temperature area that would be hazardous to enter during power operation. These valves will be exercised closed during cold shutdown and refueling outages.
- 35. These valves cannot be exercised during power operation because the discharge pressure of the low head S.I. pumps cannot overcome RCS pressure. These valves will be exercised during refueling outages and the reactor vessel head is removed to provide enough volume to accomodate the large flow rate. 2-SI-19 will be partially stroked during the monthly pump test.
36.
HCV-2936 is in its safety position and will be exercised during cold shutdown and refueling outages.
37.
These are manual valves ar.d they are in their-intended safety position (closed).
They will be exercised during refueling when the wet layup system is p%ced in operation.

These valve are in their intended safet position (open).
A failure in the closed position may damage a charging pump in the event of an auto start.
These valves will be exercised at cold shutdown when the charging pumps are not required to be operable.
39.
To exercise these valves would require leakage testing as per T.S. 4.4.6.2.2.
The leakage testing disturbs 2-SI-93 downstream which requires a containment entry to test. These valves will be exercised each refueling.
