during the periodic performance assessments that cause the systems or components to

deviate from design requirements (see 10 CFR 830.122(c)(2)). Contractors should also

identify any root causes of performance degradation (see 10 CFR 830.122(c) (3)).

Contractors should routinely monitor, collect, trend, and analyze performance data

(including thermal, hydraulic, electrical, and mechanical data). Calibrated

instrumentation should be used when performing these activities (see 10 CFR 830.122(e)

(4) and (h) (2)). The methods of implementation should include procedures, checklists,

or other guidance documents necessary to conduct these activities.

Cognizant System Engineers should maintain cognizance over performance monitoring

activities on assigned systems. Their responsibilities should include the identification of

performance goals and acceptance criteria consistent with the associated SSC design

requirements. 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.

Recognition of interfaces with existing maintenance program requirements is necessary.

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

requirements to ensure operability of the equipment within established limits. The results

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

equipment to deviate from the design requirements. Surveillance testing techniques are

similar in many ways to those used in SSC performance monitoring. The results of

surveillance testing should be reviewed and trended, and necessary corrective actions

taken to return equipment performance to within the design requirements. The periodic

equipment performance monitoring function should take credit for periodic surveillance

testing, where appropriate. Periodic testing, beyond that in the TSR surveillance

requirements, may be adjusted both in frequency and degree of technical content based

on the importance of the SSC or the particular SSC function. The origin of various

testing requirements should be documented and maintained in the MIP as specified in

DOE O 433.1, Maintenance Management Program for DOE Nuclear Facilities.

Contractors should include the design engineers, as well as Cognizant System Engineers,

in the periodic review of operating and maintenance procedures to alert maintenance and

other organizations to any design changes in the affected systems.

Resolution of Open Items

Contractors should document assessment findings as open items if they are validated to

involve one or more of the following:
