Facility Life-cycle Phase

DOESTD107393

1.4.2.7 Facility Life-cycle Phase

The life-cycle of a facility includes a design phase, a construction phase, an operational phase, and a

shutdown/deactivation phase. A major renovation or redesign phase is needed in some cases because

the DOE programmatic mission for a facility may shift and significant facility changes may be involved.

The phase of the facility life-cycle determines the relative importance of, and thus the degree of

emphasis on, issues such as design basis, design requirements, current as-bult configuration

information, system acceptance and preoperational testing, design control programs, periodic operability

surveillance programs, document control programs, facility life extension efforts, and decommissioning

plans. The facility life-cycle indicates the amount of emphasis and rigor that is appropriate at various

stages in the life of the facility.

Once the life-cycle phase has been taken into account, the upgrade actions necessary to meet the

facility-specific criteria have been defined.

1.4.2.8 Phased Implementation

The CM program plan establishes schedule milestones, each defined by and associated with a specific

deliverable. These milestones form the basis for implementation scheduling. Most facilities have

multiple safety improvements in the planning or implementation stages at any given time, and the CM

program upgrade actions need to be integrated with these improvements. The improvements on the

composite list of should be prioritized and appropriate schedules developed. The schedules should

provide for implementation over a specific period, with due consideration of facility needs and resources

that can realistically be expected to be available. The availability of qualified personnel and program

funding can influence the achievable schedule for implementing the CM program.

The CM program plan should discuss the prioritization methods used to establish phased

implementation and explain why the priorities are appropriate for the facility and its situation. It should

also discuss the feasibility of the work involved in attaining each of the top-level and intermediate

milestones: Are sufficient resources available? How does the priority assigned the CM program

compare with that of other programs? What are the most likely causes of delays or interruptions in

implementation of the CM program?

From an overall CM program perspective, the greatest impact of the graded approach is related to the

facility size and complexity. A significant impact can arise from consideration of the facility remaining

lifetime, because many facilities may have relatively short remaining lifetimes. Another significant impact

is related to the number of SSCs selected to be included in the CM program.

Two CM program elements, change control and document control, are continuous processes. The

graded approach should not be used to eliminate any steps or functions from these processes. The

level of effort for processes is generally determined more by the number of items entering the process

than by the graded approach. Management may decide to tailor the degree or rigor of certain functions

based on SSC importance. For example, adjusting the degree of technical and management reviews to

be commensurate with SSC grades would be expected.

The DR adjunct program is the portion of the overall CM program most amenable to a graded

approach. Adjustments in design information searches, regeneration, and documentation are

determined primarily by the SSC grade. For the MCA adjunct program, on the other hand, the graded

approach is based on facility-level rather than SSC-level considerations. Many facilities may need no

further MCA activities beyond estimating the facility remaining lifetime and preparing the MCA program
