The Inservice testing program for ASME Section XI Class I, 2, & 3 valves meets the requirements of subsection IWV of Section XI, 1980 edition, winter, 1980 addenda of the ASME Code. Where code requirements are determined to be impractical, specific requests for relief are written, referenced in, and included with the tables. The tables list allucode Class 1._2 & 3 valves which have been assigned a specific code category as directed by Subsection IWV of Section XI. The tables are organized by system and further identified by code class and code category, using P & ID references.

Each valve, after installation and prior to service, will be tested as required by Subsection IWV-3100 Section XI of ASME. These tests will be conducted under conditions similar to those to be experienced during subsequent inservice tests.

_4_ .

o The following information is included in the summary tables.

A. SYSTEM The system in which a valve is located is denoted by the abbreviated system identification.

B. P & ID The P & ID column references the specific P & ID number and sheet number, which the valves are located on.

C. REVISION & DATE The revision and date corresponds to the most current revision in use at the date the program was written.

D. PAGE The pages are number sequentially and show the total number of tables.

E. VALVE NUMBER The valve number references the unique Byron Station equipment pleco number (EPN). This specific valve number identifies the unit and system.

A F. COORD The coordinates reference a specific location on a particular P & ID, via an X-Y coordinate system.

G. CLASS The class refers to the ISI class assigned to the specific valve.

H. VALVE CATEGORY The valve category identifies the valve category defined in subsection IWV of ASME Section XI, paragraph IWV-2200.

I. VALVE SIZE The valve size lists the nominal pipe size of each valve in inches.

O J. VALVE TYPE A

The valve type categorizes the valve as to its valve design. The following abbreviations will be used to identify specific valve types:

Gate GA Globe GL

~ Butterfly BTF Check CK Safety SV Angle Relief RV Diaphragm Seated D Plug P K. ACT TYPE The actuator type identifies the valve actuator. The following abbreviations will be used to designate specific types of valve actuators:

Motor Operated M0 Air Operated A0 Hydraulic Operated H0 Self Actuated SA Manual M Solenoid Operated SO A

L. NORMAL POSITION Normal position identifies the normal operating position of a specific valve. O for open and C for closed.

M. STROKE DIRECT The stroke direction identifies the direction the valve actuator moves a specific valve stem to place the valve disc in a position to perform its designed safety function. O for open, and C for closed. This i identifies the direction the valve stem will move to be tested.

i Note: In order to stroke a valve in the direction required for its

! safety function, it must first be stroked in the opposite direction to l place the valve in a position to be tested. By virtue of thin, such

! valves are stroke tested in both directions. Therefore, the program I

plan specifies only the direction in which valves must be stroked to be timed.

N. TEST METHOD D-The test method column identifies specific tests which will be performed on specific valves to fulfill the requirements of Subsection IWV of Section XI. The tests and abbreviations used are as follows:

1. Seat Leakage Test (Lt)

The seat leakage tests will meet the requirements of IWV-3420, for Category (A) valves. On these valves seat leakage is limited to a specific maximum amount in the closed position for fulfillment of their function.

2. Full Stroke Test (St)

Valve exercising tests of Category A and B valves will be performed in accordance with IWV-3410. The test will include full stroke testing to verify operability in the direction required to fulfill the required function.

3. Check Valve Exercise Test (Ct)

The check valve disc will be exercised to the position required to fulfill its safety function in accordance with IWV-3520.

4. Relief Valve Setpoint Check (Rt)

A Relief valve setpoints will be verified in accordance with IWV-3510 of ASME Section XI.

5. Fail Safe Test (Ft)

Valves with fail safe actuators will be tested to verify the valve operator moves the valve stem to the required fail safe position upon interruption of the motive force in accordance with IWV-3415.

6. Position Indication Check (It)

Valves which are identified to require a PIT will be inspected in accordance with IWV-3300 of ASME Section XI.

! 7. Part-Stroke Test (Xt)

If only limited operation is practical, during plant operation the valves shall be part-stroke (Xt) exercised during plant operation and full-stroke exercised during cold shutdowns, in accordance with IWV-3412 and IWV-3522.

O. MAX STROKE TIME The maximum allowable stroke time is specified in seconds for power operated valves requiring a full stroke (St) test in order to meet the

"' requirements of IWV-3413, where (N/A) is not applicable.

P. TEST MODE A

Denotes the frequency and plant condition necessary to perform a given test. The following abbreviations are used: .

Normal Operation OP Tests designated OP will be done once every 3 months.

Cold Shutdown CS In-service valve testing at cold shutdown is a valve testing program which commences within 2. hours after the plant reaches a cold shutelown condition but in no case later than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after cold shutdown 1:

reached. Completion of cold shutdown valve testing is not a prerequisite to plant startup. Valve testings which are not completed during a cold shutdown shall be completed during subsequent cold shutdowns that may occur to meet the code specified testing frequency.

'- 'In case of frequent cold shutdowns, valve testing need not be performed more of ten than once in a three-month interval for any valve with a tent mode designation of cold shutdown. When plant conditions (system orientation) are aligned such that specific valves cannot be tested at the interval prescribed, the situation will be documented and tracked with the ISI Program.

In the event a valve must be declared inoperable as a result of cold

,pg shutdown testing, the applicable unit startup limitations will be as stated in the Technical Specifications, Limiting Condition for Operation.

Reactor Refueling RR Tests with this designation will be conducted during reactor refueling outages only.

Q. RELIEF REQUEST Relief Requests references a specific request for relief from Code Requirements. All Relief Requests are included immediately following the presentation tables. More Valve Relief Requests may be necessary for the Valve Inservice Inspection Program and will be identified during the performance of the Preservice Inspection.

7. Justification:

Full stroke testing of these check valves will be demonstrated by total pump discharge flow during cold shutdown providing the reactor vessel head is removed. Performance of this test with the reactor coolant system depressurized but intact could lead to an inadvertent overpressurization of the system. The alternative method of protecting against overpressurization by partial draining of the reactor coolant system to provide a surge volume is not considered a safe practice due to concerns of maintaining adequate water level above the reactor core.

5. Basis for Relief:

Component cooling water flow to the reactor coolant pumps is required at-all times while the pumps are in operation. Failure of one of these valves in a closed position during an exercise test would result in a loss of cooling flow to the pumps and eventual pump damage and/or trip.

jeg 6. Alternate Testing:

These valves will be exercise tested during cold shutdown providing all reactor coolant pumps are not in operation. This testing will be each refueling outage as is maximum.

7. Justification:

Per IWV-3522 and IWV-3412 exemption is taken to the quarterly exercise test of these valves since it is impractical to test these valves during normal operation as pump damage and/or a reactor trip would result.

Exercise for operability (St & Ft) of category A & B walves every 3 months per 1WV-3411.

5. Basis for Relief:

These check and isolation valves cannot be tested during unit operation as main feedwater would be terminated causing a reactor trip. These valves main function is to provide water flow as the normal heat removal for the steam generators.

p pm 6. Alternate Testing:

To avoid any transient, these valves will not be full stroke tested I during unit operation or hot shutdown conditions. These valves can only be tested at cold shutdown whenever the feedwater and condensate systems are not in operation. Although, partial stroke testing will be donc during operation.

7. Justification:

In cold shutdown the steam generators are placed in the " wet layup" condition with the secondary side essentially filled with feedwater.

Stroke testing in this condition with the feedwater or condensate system l

running could lead to an inadvertant overfill in the main steam piping.

The potential of overpressurizing the secondary side of the steam generators would then exist. This testing period will be each refueling

outage as a maximum.
