III. MAINTENANCE STRATEGY
A. Balance of Maintenance Approach
1. Performance Standard
The maintenance program includes the proper balance of the various approaches to maintenance, e.g., preventive, predictive, or corrective. The approach is adequately documented with consideration of economics and reliability of equipment or components, and their affect on reliable operation of the unit. Operating experience is factored into the program. Maintenance procedures and documents should include the generation equipment and all those components owned by the generation owner directly connected to the plant that are an integral part of delivering power to the grid including fuel supply systems, electrical switchyards, transmissions lines, penstocks, flumes, exhaust system, etc.
2. Assessment Guidelines
A. Preventive maintenance is proper for the equipment whose failure adversely impacts safety or reliable operation or results in forced outages, or significant derates.
B. Preventive maintenance is appropriately balanced between time based and condition based, as appropriate for the equipment.
C. The preventive maintenance program is supported by a master equipment database.
D. Preventive maintenance tasks are technically based, including vendor input and industry experience.
E. Preventive maintenance tasks are properly documented in procedures, and receive appropriate planning prior to scheduling.
F. Qualified personnel perform preventive maintenance tasks.
G. Preventive maintenance is effectively coordinated into operational and outage planning to prevent unnecessary repetitive removal of equipment from service for maintenance.
H. Predictive maintenance data receives appropriate technical review and is trended to predict when maintenance should be done to prevent failure.
I. Predictive maintenance data is captured in equipment history in a manner to support maintenance analysis and equipment performance problem analysis.
J. Performance of predictive maintenance is monitored through effective performance measures.
K. The effectiveness of predictive maintenance tasks is periodically reviewed for effectiveness.
L. Equipment or components that are degraded or not performing their intended function are restored in a timely manner, consistent with their respective importance to personnel safety and efficient, reliable operation of the unit.
M. Perform activities that can affect personnel safety or plant reliability only after safety and operational assessments, detailed planning and scheduling, job briefings, and coordination with all necessary personnel have been completed.
N. Personnel should be knowledgeable of maintenance work activities that may result in changes in plant configuration, e.g., unauthorized part substitutions, repairs that do not comply with design specifications or code requirements.
O. Schedule work to maximize critical system availability and to ensure maintenance can be performed within committed time limits.
P. Post maintenance testing, sufficient to verify that functionality has been restored, is performed prior to restoring equipment to service.
