Phased Implementation - s1073ch30003

program is based on the completeness, accuracy, and full documentation of existing design

information. The DR program plan should present the results and recommendations of the technical

management review performed under the design requirements element of the CM program. It should

reflect the graded approach and provide the basis for its application. The DR program plan should also

reflect the relevant findings of the initial assessments, including:

Location of design documents

Availability of design documents

Control of design documents

Consistency of information among design documents

Immediate actions taken and planned

Four examples of different situations regarding the availability and reliability of existing design

information are:

Almost no information readily available

Moderate amount of information available; some essential information not readily available

Moderate amount of information available; reliability of information questionable

Vast amount of information available that is highly trustworthy

The DR program plan should identify key interfaces with other programs. For example, the Safety

Analysis Report (SAR) upgrade program is an important interface to establish. To this end, the DR

program would need to include early coordination with the SAR upgrade program to prevent duplication

and to ensure the effectiveness of both programs. The program plan should define interfaces with the

design requirements program element of the CM program and other CM program elements.

Phased Implementation. The DR program is performed in a phased manner with defined milestones

and associated deliverables. A phased approach to design reconstitution provides for an initial set of

design information, with further design information added as it is reconstituted. Each activity should be

scoped, prioritized, staffed, and funded as appropriate to ensure attainment of the defined milestones.

The program criteria call for the DR program plan to be provided to DOE for review within 6 months

after the CM program plan is provided. Thus, the DR program plan may be provided to DOE up to 24

months following the initiation of CM program planning. Design reconstitution program activities should

not be implemented before an adequate CM change control element is available. Sample milestones

in design reconstitution beginning from the time DOE reviews the DR program plan (see Figure 32)

are as follows:

DR action plan (0-6 months)

Formal review (6-12 months)

Smart search (1-2 years)

Comprehensive search (2-4 years)

regeneration of design requirements (2-5 years)

Pilot DIS program (2-5 years)

DIS Revision 0 completion (4-6 years)

Regeneration of design basis (4-6 years)

Field validation of DISs (5-7 years)

DIS Revision 1 completion (5-7 years)

The issuance of completed DISs is also phased by system and topic; as individual DISs are completed,

they are issued. The phased preparation and issuance of DISs should be consistent with priorities

established by the DR program plan.
