2.5.3.3 Periodic Equipment Performance Monitoring

This ongoing assessment function verifies that selected SSCs continue to be able to perform their

intended functions (i.e., meet their design requirements). Equipment performance monitoring is

included in the CM program because it is important to maintaining the bonds between the physical

configuration and the design requirements. The results of this monitoring function should be used to

correct any equipment deficiencies that cause the equipment to deviate from the design requirements

and to identify any root causes of performance degradation.

The fully developed program should include (1) implementing procedures established to specify and

control periodic equipment performance monitoring, (2) acceptance criteria defined consistent with the

design requirements, and (3) testing procedures established for frequently performed tests.

Performance monitoring programs should be implemented to routinely monitor, collect (using

calibrated instrumentation), trend, and analyze performance data (including thermal, hydraulic,

electrical, and mechanical data) for SSCs within the CM program. The methods of implementation

should include procedures, checklists, or other guidance documents necessary to conduct these

activities. Specific facility personnel, such as system engineers, should be assigned to each SSC and

held responsible for the performance monitoring activities on assigned SSCs. This responsibility should

include the establishment of performance goals and acceptance criteria consistent with the associated

SSC design requirements. Examples of major tests that should be included in the performance

monitoring program are as follows:

Heat exchanger performance tests (e.g., fouling and heat transfer rate)

Pump performance tests (e.g., head versus flow tests)

Valve performance tests (including stroke times)

Vibration monitoring for major rotating equipment

Battery capacity and performance tests

Other major equipment tests, as applicable (e.g., diesel generators and inverters)

The frequencies for each test should be specified in procedures and periodically reviewed to ensure

adequacy. Reviewing trend graphs of collected equipment data at specified intervals is a proven,

effective approach. For example, if the trend graph indicates that the equipment likely will not meet the

acceptance criteria at or before the next scheduled test, an adjustment in the test schedule and other

maintenance actions would be necessary.

For cost-effective implementation of this function, the timely recognition of interfaces with existing

program requirements is necessary. The equipment monitoring function interfaces with operations,

maintenance, and systems engineering programs. In some cases, adjustments to existing programs

may be sufficient to satisfy the need for ongoing CM assessments. Existing programs should be

reviewed to determine whether they are adequately oriented to maintain configuration and support the

objectives of the CM program and are adequately integrated with other important CM functions. They

should also be reviewed to determine whether their scope is sufficient to address the full breadth of

SSCs within the CM program.

Surveillance testing is typically performed to satisfy regulatory, code, or other requirements to ensure

operability of the equipment within established limits. For SSCs included in the CM program the results

of surveillance testing should be used to detect and correct any deficiencies that cause the equipment
