Implementation of Changes

DOESTD107393

approvals necessary prior to implementation have been obtained. On the basis of these reviews,

management should take approval action.

1.3.4.4 Implementation of Changes

Each change should be implemented in accordance with its approved change package. The change

process should include mechanisms for field change requests, and technical reviews and approvals of

field changes should be commensurate with those of the original change package. The change

process should generate accurate as-built information. After the physical implementation of changes,

post-modification testing should be conducted (see criterion 1.3.5.4).

1.3.4.5 Documentation of Changes

Each change should be documented and that documentation should include a description of the

change, as well as an account of the technical reviews, management approvals, as-built information,

and post-modification test results. Documents that are included in the CM program and are affected by

a change, either directly or indirectly, should be revised.

The objective of the assessments element is to help define facility configuration management needs

and to measure how effective the CM program is in establishing and maintaining the program's basic

relationships. Configuration management assessments are conducted in an initial phase, in a post-

implementation phase, and throughout the life of the facility.

1.3.5.1 Programmatic Assessments

The adequacy of CM programs and procedures should be assessed using vertical and horizontal slice

assessments.

Initial assessments. During the planning for the CM program, initial assessments should be

conducted to determine the strengths and weaknesses of existing programs and procedures with

regard to determining where upgrade actions and resource investments are necessary. Two

vertical slice assessments relevant to the facility should be conducted. One of these should be on

a safety system related to the principal facility hazard, either nuclear or non-nuclear. Two

horizontal slice assessments relevant to the facility should also be performed. One of these

should be on change control and the other on a technical topical area, such as seismic

qualification or fire protection.

Post-implementation assessments. After the CM program upgrades are implemented, a

horizontal slice assessment should be performed for each CM program element to determine if

that element addresses identified weaknesses and is effective in accomplishing the CM functions.

For each system design information summary (DIS) developed by the DR adjunct program, a field

validation should be performed to ensure that the design requirements are accurately reflected in

the physical configuration and the associated facility documentation. After the MCA adjunct

program is developed, a technical quality review should be performed of its assumptions,

methods, and products.

Periodic effectiveness assessments. After the CM program and its adjunct programs have been

implemented, a combination of vertical and horizontal slice assessments should be performed

periodically to measure the overall CM program effectiveness and to determine if CM controls are
