Grading Based on Facility Operational Status and Lifecycle Phase
Configuration Management - index
Grading Based on Programmatic and Technical Issues

Configuration Management
current as-built configuration information,
system acceptance and preoperational testing,
design control programs,
periodic operability surveillance programs,
document control programs,
facility life extension efforts, and
decommissioning plans.
If a facility is deactivated or being decontaminated or decommissioned, there are
different considerations than during the operating phase. For example, during a
maintenance shutdown at an operating facility, a pump with a safety function may be
disassembled or removed. Before operation, that pump would need to be restored or
replaced with a pump that meets the existing or new design requirements. In addition,
performance testing would likely be needed. These changes and tests would need to be
processed through the configuration management process. On the other hand, if the same
facility is deactivated two years later with no intention of resuming operation, then the
pump may no longer have a safety function. If the pump with no safety function is
removed and it is no longer needed, configuration management for that action may be
reduced to a simple documentation of removal of the pump.
Contractors for facilities in deactivation status that may be returned to an operating status
later will need to implement a configuration management process that maintains the
design requirements for the facility and accurately documents the configuration of the
facility. Accurate documentation will facilitate the later reactivation of the facility. In
addition, the contractors should take actions through the maintenance process to ensure
that the physical configuration does not degrade and that changes are identified and
If during the deactivation period the scope of SSCs under the configuration management
process was reduced to only include the SSCs related to personnel safety during
deactivation, contractors may need to re-establish the design requirements of the balance
of the CM SSCs for operation. Contractors would also need to perform walkdowns to
determine the degree of correlation between the physical configuration and associated
documentation. Physical changes would need to be reviewed, approved, and
documented. Consequently, when determining the scope and depth of configuration
management to be pursued during deactivation, contractors should consider the
probability of reactivation, the length of time prior to reactivation, and the cost of
reactivation if the configuration management was limited during reactivation. In some
cases it will be more cost effective to maintain robust configuration management and
maintenance processes. In other cases (e.g., long reactivation periods with a low
probability of reactivation) it may be more cost effective to reduce the configuration
management process to address only those SSCs important to safety during the
reactivation period.
