be able to establish a configuration management process that envelopes expected
operations or is modified with changing missions.
Because it is easier to establish and implement a configuration management process for a
new facility, facility remaining lifetime will be a less significant factor in grading the
configuration management process for a new facility.
3.10.5 Grading Based on Facility Operational Status and Lifecycle Phase
The facility operating status and life-cycle stage indicate the amount of emphasis and
rigor that is appropriate for the configuration management process. The life-cycle phases
of a nuclear facility include:
During the early part of the design phase, designers may need to make rapid changes
unhampered by configuration control, but as the design interfaces are established, design
requirements will need to be documented and controlled to ensure systems will function
properly and construction can proceed.
During construction, which will likely overlap the final design phase, configuration
changes need to be controlled and documented, but the contractor will continue to need a
configuration management process that responds rapidly and provides timely resolutions
to keep construction on schedule.
If the facility is currently operating (including periodic shutdowns for maintenance and
other conditions), the operational status consideration generally does not affect the
grading of the configuration management process. However, during a major
modification to an existing facility, contractors will need the configuration management
process to be as responsive as when a facility is in the construction phase. In particular,
the contractor must be vigilant that the changes in one part of the facility that affect
another part of the facility are properly evaluated, approved, and documented. In
addition, if part of the facility is operating during the modification, some of the
configuration considerations of an operating facility will remain in effect. The phase of
the facility life cycle during the modification will determine the relative importance of,
and thus the degree of emphasis on:
