Physical Configuration Assessments

adequate and appropriate. The results of these assessments should establish the basis for

revisions to the CM program plan, either increasing or decreasing controls.

1.3.5.2 Physical Configuration Assessments

Physical configuration assessments, or walkdowns, should be performed for representative sample

SSCs to determine the degree of agreement between the physical configuration and the configuration

depicted in the facility documentation. Physical walkdowns should be included as part of the

programmatic assessments conducted during the initial assessments, post-implementation

assessments, and periodic effectiveness assessments. If substantive discrepancies (either in number

or type) are discovered, appropriate immediate corrective actions should be developed to establish

agreement between the physical configuration and the documentation. The corrective actions should

include additional walkdowns to characterize the problem and to determine the extent of the problem.

They should also include technical evaluations to determine whether the physical configuration or the

documentation should be changed.

1.3.5.3 Periodic Equipment Performance Monitoring

Structures, systems, and components within the CM program should be tested periodically to

determine it they are still capable of meeting their design requirements. This monitoring should also

address surveillance actions, periodic in-service inspections and tests, and other monitoring of SSCs to

ensure safe and reliable operation of the facility. Monitoring should also include measurements and

trending of data related to the actual aging degradation of equipment, to the extent identified by the

MCA adjunct program and approved by the design authority.

1.3.5.4 Post-Modification Testing

An SSC within the CM program should be tested after modification (and before being turned over for

service) to determine if it is capable of meeting its design requirements (i.e., the post-implementation

acceptance criteria). If a changed SSC fails to meet its post-implementation acceptance criteria,

turnover for operation should be postponed until either a technical review has been completed and any

follow-up actions are completed or until the SSC is returned to its original condition and tested

satisfactorily.

The objective of the DR adjunct program is to establish, organize, and document design information

(i.e., both design requirements and design basis), where existing design information is not adequate.

1.3.6.1 Program Plans and Procedures

A program plan, an action plan, and implementing procedures should be developed for the DR adjunct

program. The DR program plan should be based on the initial assessments and the graded approach.

The DR adjunct program should be implemented in stages to provide a timely initial set of design

information and more information as it becomes available. It should include prioritization of the

development and issuance of DISs. Design information summaries for systems or technical topics

necessary to support the facility accident analysis and TSRs should receive the highest priority. The

DR program plan should address the same topics identified for the CM program plan (described in

criterion 1.3.1.1.c).
