Maintenance Importance Generator (MIG).

DOE-STD-1053-93

2.7

A computerized sy stem using

predetermined rules to compare data on an MJR and to establish relative-importance

ranking for each maintenance job.

2.8

Maintenance Job Request (MJR.) (Appendix D). Means of obtaining maintenance

services available on both paper and electronic mediums and initiated by maintenance

customers. Issued to Maintenance Planners and Estimators and used to define, plan,

and execute maintenance activities. Documentation of a deficient equipment condition,

requires detailed documentation of work performed, spare parts, procedures, or testing

to verify maintenance was performed correctly. The MJR. may also serve as

documentation for completion of minor maintenance activities such as lubrication, light

bulb replacement, etc.

Maintenance Management. The administration of a program utilizing such concepts

2.9

as organization, plans, procedures, schedules, cost control, periodic evaluation, and

feedback for the effective performance and control of maintenance with adequate

provisions for interface with other concerned disciplines such as health, safety,

environmental compliance, quality control, and security. All work done in conjunction

with existing property is either maintenance (preserving), repair (restoring), service

(cleaning and making usable), or improvements (modification). The work to be

considered under the DOE maintenance management program is only that for

maintenance, repair, and modification (temporary).

Outage. Condition existing whenever normal operations has stopped, due to planned

2.10

or unplanned occurrences.

Performance Test. A test of SSC to verify that required performance characteristics

2.11

may be achieved, to detect any abnormal performance characteristics, and to determine

the effect of maintenance and operating activities on equipment performance.

Performance Monitoring. Systematic monitoring and trending of the performance of

2.12

selected plant SSC to measure and assess the impact of any performance changes on

overall plant efficiency, reliability, and availability.

Periodic Maintenance. Preventive maintenance activities accomplished on a routine

2.13

basis (typically based on operating hours or calendar time) and may include any

combination of external inspections, alignments or calibrations, internal inspections,

overhauls, and SSC replacements.
