Types of Maintenance

DOE-STD-6003-96

4.4.6.3 Types of Maintenance

The maintenance program should include surveillance to obtain in-service performance

and operational data; predictive maintenance to analyze data collected from surveillance; pre-

ventive maintenance based on manufacturer's recommendations, operating experience, good

engineering practice (including aging concerns), and predictive maintenance feedback; and cor-

rective maintenance, as necessary. The maintenance program should ensure that recommen-

dations and information from industry and individual vendors are reviewed and considered for

incorporation into appropriate areas of the program.

4.4.6.4 Work Control Process

The work control process should be based on procedures that provide for the identifica-

tion of deficiencies, planning and preparation for work, setting appropriate conditions for work,

work procedures, supervisory authority, documentation of completed work, postmaintenance

testing, return-to-service procedures, and review of completed work packages. The work control

process begins with the identification of deficiencies or the need for planned or predictive main-

tenance and the generation of a maintenance request. Planning and scheduling activities should

then be performed. The work package should specify the appropriate plant conditions for the

work; define the required isolation or tagouts and component deenergization; incorporate appro-

priate QA, quality control (QC) functions, and ALARA considerations; and require appropriate

supervisory authorization prior to starting work. The work package should contain postmainte-

nance testing requirements and clearances or return-to-service procedures, provide for docu-

mentation of completed work, and provide for a review of the completed package. The post-

maintenance testing program should establish specific performance acceptance criteria that

ensure a high level of confidence in the ability of the component to perform its design function

when returned to service.

Process indicators, which provide information regarding the effectiveness of execution

of the elements of the maintenance program, should be monitored to provide insight regarding

potential problem areas in the conduct of maintenance activities. Examples are postmainte-

nance test results, periodic surveillance test results, ratio of preventive to corrective mainte-

nance, maintenance work order backlog, time to restore component function after failure dis-

cover, and frequency of rework.

4.4.7 Training and Qualifications

The responsibilities and authority for training and certification must be specific, and

appropriate plans and procedures must be developed and implemented. Each fusion facility

should be responsible for the following:

a. Develop and implement a training and qualification program using a graded approach

based upon the hazards of the facility.

b. Prepare, approve, and implement a training plan that sets forth the staffing, training,

and qualification requirements.
