POST-MAINTENANCE TEST. Applicable and appropriate testing performed following

maintenance to verify that a particular structure, system, and component, piece of

equipment, or process performs its intended function based on its design criteria and that

the original deficiency has been corrected and no new deficiencies created. In some

cases, the extent of a particular postmaintenance test may extend beyond the component

or piece of equipment that has been repaired, replaced or modified to complete systems

or processes, depending on the type of maintenance action performed and the affect that

the component or piece of equipment has on the total system or process. [DOE G 433.1-

POWER PLANT EXPERIENCE. Experience acquired in the testing, operation, or

maintenance of power generating facilities. Experience in design and construction may

be considered applicable power plant experience and should be evaluated on a case-by-

case basis. [DOE O 5480.20A]

465.

PREDICTIVE MAINTENANCE. Predictive maintenance consists of the actions

necessary to monitor, find trends, and analyze parameters, properties and performance

characteristics or signatures associated with structures, systems, and components (SSCs),

facilities or pieces of equipment to discern whether or not a state or condition may be

approaching which is indicative of deteriorating performance or impending failure, where

the intended function of the SSCs, facilities or pieces of equipment may be compromised.

Predictive maintenance activities involve continuous or periodic monitoring and

diagnosis in order to forecast component degradation so that "as-needed" planned

maintenance can be initiated prior to failure. Not all SSC, facility or equipment

conditions and failure modes can be monitored and diagnosed in advance; therefore,

predictive maintenance should be selectively applied. To the extent that predictive

maintenance can be relied on without large uncertainties, it is normally preferable to

activities such as periodic internal inspection or equipment overhauls. [DOE G 433.1-1]

PRELIMINARY DOCUMENTED SAFETY ANALYSIS. Documentation prepared in

connection with the design and construction of a new DOE nuclear facility or a major

modification to a DOE nuclear facility that provides a reasonable basis for the

preliminary conclusion that the nuclear facility can be operated safely through the

consideration of factors such as
