1.1.1 Each motor-operated and air-operated valve shall be demonstrated OPERABLE by actuating to the position designated on the data sheets within the maximum

&1lowable stroke time limit.

1.1.2 Each air-operated valve shall upon loss of actuator power procure its fail-safe position.

1.1.3 Each check valve shall. be demonstrated OPERABLE by being exercised to the position to fulfill its func-tion.

SURVEILLANCE FREQUENCY:

SP1- Special; Surveillance execution shall be determined by the time elapsed since this procedure's last execution and planned duration of the outage. If this outage is planned to exceed 48 hrs. in cold shutdown, or due to unforeseen circumstances the out-age exceeds 48 hrs., then determine the time elapsed since this procedure's last execution. If the period of time between the last execution of this procedure is greater 'than or equal to three (3) months (92 days), execution is required. If the procedure was partially completed, start with those valves not tested during the Surveillance Procedure's performance. (See OP-209, Plant Cooldown, Section 6.2.)

NOTE: The period of cold shutdown does not have to be extended solely for the complete performance of SP-435, but attempt to test as many valves as possible. If the procedure has been fully

completed within the last three (3) sonths, execution is not required.

SP2- Special; Immediately prior to returning to service a power-operated valve or check valve that has had maintenance, repair, or replacement of the valve, or actuator, or control / power circuit, a test shall be conducted in which demonstrates the OPERATIONAL READINESS of the particular valve.

R- Refueling; The positions of the valves denoted by asterisks are to be compared to the positions shown by the associated remote indicators.

FREQUENCY NOTES:

23 - Prior to returning equipment to service.

40 - Establish surveillance prior to ascending into the applicable mode.

54 - If cold shutdown is planned to exceed 48 hrs., or due to unforeseen circumstances exceeds 48 hrs., execution of this surveil-lance is required if SP1 condition applies above.

4.0 ACCEPTANCE CRITERIA 4.1 The maximum allowable stroke time, as specified on Data Sheet II and III, for each valve is not exceeded.

4.2 Each check valve is exercised *.o the position required to fulfill its function.

4.2.1 The valve disc in normally open check valves closes on cessation or flow reversal.

4.2.2 The valve disc in normally closed check valves opens when flow is established.

4.3 Valves with fail-safe actuators achieve their fail-safe positions upon loss of actuator power.

4.4 When demonstrating condenser hotwell flow paths between EFP-1 and EFP-2 through EFV-2 and ETV-1, respectively, the water level in CDT-1 shall decrease by approximately one foot per valve.

4.5 The remote indicator positions accurately reflect the actual local indicator positions.

4.6 When verifying operability of EFV-5, 6, 7, 8, 15, 16, 17 & 18, and FWV-43 and 44, flow of approximately 200 l18 gpa to each OTSG shall be obtained to verify the full l stroke of these valves.

5.0 SPECT17. TEST EQUIPMENT 5.1 Stopwatches 5.2 Two hundred feet (200 f t. ) of hose for demineralized water and appropriate connections.

5.3 Container to hold a minimum of one gallon of liquid.

5.4 Funnel NOTE: The items mentioned in 5.2 through 5.4 are for performing the test in Section 9.5.

6.0 LIMITATIONS AND PRECAUTIONS 6.1 Verification of valve stroke time may be ma'de at a remote operating station using indicator lights or at j the valve using proper stem motion. Local verifica-l tion should be coordinated with the Control Center.

6.2 The remote position indicators (denoted by asterisks on Data Sheet III) shall be visually observed at least as frequently as scheduled refueling outages with at least one observation being made every two years.

6.3 Prior to operating any valve, permission must be obtained from the Nuclear Shift Supervisor.

6.3.1 Prior to Uperating MUV-253, 258, 259, 260, and 261, operating personnel should be stationed at the local controls to manually open these valves in the event remote reopening is unsuccessful.

6.4 Those valves on Data Sheet II that require time-stroking shall be coordinated with the execution of OP-209, Plant Cooldown, and OP-404, Decay Heat Removal System, during power descent into cold shutdown.

6.5 When the deray heat removal system is in operation, iq aqt close DHV-3, 4, or 41 unless the reactor coolant pumps (RCPs) are available to cool the core.

CAUTION: Prior to injecting water from CDT-1 into the [19 OTSGs for this test, contact Chemistry l Supervision to ensure efforts have been made [

to provide as high a water quality as l zeasonably possible. This may involve [

tleanup of the CDT-1 via the hotwell and [

condensate de= = ralizers before actual l testing occurs. [

eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeessenesessessessessesse 6.6 Section 9.10 of this procedure will inject water from the Condensate Storage Tank to the OTSGs. Due to possible water quality problems, it is imperative that the amount of water injected be minimized. All personnel involved in this test must fully understand the steps of this procedure and the required data prior to the actual performance of the test.

6.7 It is preferred that Section 9.10 of this test be [19 performed on the startuo from cold shutdown prior to [

heating the OTSGs, to limit the concentrating ef fects l of the chemicals / impurities from the CDT-1 in the [

OTSGs. This will allow cleanup of the OTSGs, after [

shutdown and testing, by OTSG blowdown to the hotwell. [

7.0 Praemmerr i-+_1 ru1TIog 7.1 This procedure is designed and written to be performed by Nuclear Operators reporting directly to the Nuclear Shift Supervisor.

7.2 Some assistance may be required from the mechanics to perform Section 9.5 of this procedure, for the attach-ment of hose connections.

7.3 For work located in radiation controlled areas, due consideration should be given to the ALARA program.

This may result in a determination that special preparations and/or precautions are necessary.

-Explanation of Enclosures-Before a non-asterisk denoted valve, shown on data sheets, is manipulated to measure stroke time, the valve's initial (NORMAL) position shall be compared to the associated remote indicator's designated position. The FULL-STROKE position of the valve and the remote indicator shall also be cespared. The top of the valve sten shall correspond to a marking implanted upon the stem housing when in the NORMAL position and in the FULL-STROKE position (or other methods which verify that remote indicators are reflective of valve stem position).

The asterisk-denoted valves' positions shall be compared at least as frequently as scheduled refueling outages with at least one (1) comparison being made every 2 yrs. If comparison is not to be performed, the data space shall be marked 'Not Applicable" (NA).

Each valve shall be restored to its NORMAL POSITION by completing the

" Restoration Position" column with the appropriate mark (0 or C).

If a valve's stroke time is within the " Alert Range" or exceeds the maximum allowable stroke time, refer to Section 11.0, Contingencies.
