the same lubricant, limit gear frames and caruidges should contain the same type oflubricant, and MOV valve stems should be lubricated with the rme !
lubricant contained within the main gear case). Standardizing the lubriennt used in each nica will reduce the pmbability of human error for mixing gicases requiring subsequent rework to pmvent intemal component degradation.
- 3. Acceptance criteria will determine whether grease is acceptable fot : ontinued usage. The acceptance criteria shall be dev-loped using industry data, manufacturer and engineering recommendations, and Station experience.
- 4. Qualitative acceptance criteria for the acceptable grenses shall be included in the PM and maintenance procedures. Color, uniformity (non hardened globules),
consistency, and contaminatica (e.g , water, foreign material) may provide ,
visualindication oflubricant degradation. Other acceptable grease examination methods involve grease penetration testing, moisture go-no go splatter testing, and visual smear examination. Lubricant inspections shall be analyzed by qualined individuals. Examinations providing finite resuhs shall be trended for condition directed lubrication rephcement determination. Samples results obtained during PM activities shall be forv,arded to the MOV.

The MOV Inspection / Verification Program shall ensure, on a periodic basis, that the j MOV Trending Program and Signature Review prtress is effective.
- a. - On a refuelin: cycle basis, the teardown and inspection of selected MOVs shall be perfomied. MOVs shall be selected that indicate acceptab!c performance (such as !
those requiring a grease change out) and MOVs suspected of degradations. The teardown process shall validate the mechanical condition of the MOV that the MOV j Trending Program and Signature Review process predict. The number of MOVs torn down will be based on plant specific experience and industry opesating experience.
- b. Prior to disassembly and visualinspection of the MOV actuator intemals, a review l of the trend infonnation and signa: ore indicators of the MOV shall be performed.
The mechanical condition shall be compared with the predicted findings. This inspection shall be documented and used for future reference. An actuator may be disassembled for any of the following reasons:
Grease change out Known mechanical problems (Scheduled Maintenance)
+ To quantify signature anomalies with actual mechanical condition (e.g. cyclic loading)
- c. The MOV Coordinator, or the MOV Engineer, may reco* w Jves to be disassembled and inspected based on MOV signatures, : . of WPTS history, or proposed outage work scope. The MOV inspections (pre 64cied vs findings) shall be documented and mai.itained by the MOV Coordinator. Any enhancements or changes to the MOV Inspecnon Verification Program, based on actual findings, shall be recommended to the Corporate Maintenance Support group for notification to the other Station, and possible revision to the MOV Program. This will ensure actual field experience is being utilized in program enhancements.

6.1.9 Past Maintenance Testing Post maintenance testing shall be performed to assure that maintenance perfonned on MOVs was implemented correctly and that the operator / valve assembly is properly set, adjusted, and ready to Fe returned to service.
NOTE: Post maintenance testing requirements specified for ASME Section XI components shall be performed as delineated in VPAP-0307, Repair and Replacement Pmgram For ASME Section XI Components.
- a. Post maintenance testing shall occur before retuming the MOV and/or MCC to Operations for service. The type and extent of testing shall be detennined by the MOV Coordinator utihzing Attachment 5, Post Maintenance Testing Guidelines For Motor Operated Valves. Additional or modified testing may be recommended by the MOV Engineer or depanment Supervisor based on the specific component or operating conditions. The work control package shall document all post maintenance testing performed on a MOV, including cross references to other work control packages or test prccedures that satisfy the original test requirements,

- 1. Comprehensive Test This test is normally utilized to establish a baseline for program i implementadon, following major maintensace activities, or as an aid in troubleshooting. 'lhis test indicates the thrust being delivered to the valve, control switch actuations, and records motor current amplitude over the endre simke of the valve. Comprehensive Tests are identified on Attachment 5 as COMP. Portions of the Comprehensive Test nuy be performed where maintenance activities dictate at the discretion of the MOV Coordinator. 'Ihese tests should be designated as SW (Switch Actuation), TilR (Thrust Reading),
and CT (Current Amplitude Trace).

- 2. MCC Test These tests are perfonned at the Motor Control Center (MCC) and sor primarily used to monitor combinations of either motor cunent, control switch settings, or bus voltage. Secondatily, these tests ate utilized to collect trending information on a PM frequency after a baseline has been established. MCC testing can also include motor power circuit meggars, control circuit gmund checks, or continuity checks of circuits or components that affect valve operation. MCC Tests are identified on Attachment 5 as MCC.
- 3. Interlock Test This test is a verification that ensures limit switch contacts interkvked to other components have not been affected by hmit switch adjustments or replacements. Interkwk Tests are identified on Attachment 5 as INT.
- 4. Thrust Verification Test Tnis test includes a measurement of delivered thrust (nonnally obtained at the valve) to ensure that the maintenance activity has not resulted in a thrust value outside of calculated tolerances. Thrust VeriGeation Tests are identiGed on Attachment 5 as TVT.
- 5. Visual Verifica; ion A visual veriGeation is nomially trquired following maintenance when settings have not tren af tered. Stroke time is nomully recorded at the same time.
Visual Verifications are identified on Attachment 5 as VIS.
