Identification and Retrieval of Source Documents

efforts are coordinated. For major design changes, it might prove necessary to accelerate the design

reconstitution of associated systems and components.

3.2.1 IDENTIFICATION AND RETRIEVAL OF SOURCE DOCUMENTS

Throughout these searches, the document control organization should provide support in locating and

retrieving the subject documents. If possible, these search activities should be coordinated with

document control activities that identify that organization's design and configuration documents.

Documents identified during the searches should be reviewed for inclusion into document control

processes and systems, such as the CM document database. A comprehensive index of design

documents is a very useful tool until design reconstitution is completed. Figure 33 shows the key steps

of source document identification and retrieval.

3.2.1.1 Formal Review

The formal review of on-hand, summary-level design documents is the first stage of identification and

retrieval of existing design information. The scope for this review should be limited to readily available,

top-level design documents such as SARs, Technical Safety Requirements, and System Design

Descriptions (SDDs), if available, and other top-level synthesis and summary-type design documents.

Through document identification and information extraction, the formal review establishes the

preliminary set of design requirements and the design basis. For facilities with inadequate design

requirements (as determined by the CM program initial assessments or otherwise), the formal review

may be needed to support initial development of certain portions of the DR program element (i.e.,

establishment of the CM equipment database, initial system categorization, and initial system grading)

and may be pursued as a priority action within CM program implementation.

3.2.1.2 Smart Search

The smart search identifies and retrieves those types of documents most likely to contain design

requirements. It culminates in the identification of most of the retrievable design requirements as well

as the design basis information contained in the associated source documents. The smart search

provides an expedited input to the CM equipment database for use by design and other facility

personnel. The documents that are most likely to contain design requirements are the design output

documents. These documents include drawings, specifications, load lists, valve lists, operational

setpoints, maintenance and test requirements, and construction and installation instructions. Further

examples of design output documents are provided in Appendix IIB.

Experienced personnel can provide insight into the most likely document types and their locations.

Experienced facility personnel might know of facility-specific documents that are not design output

documents but are likely to contain design requirements; the smart search should target these

documents. While certain design analyses and calculations might contain design requirements, such

documents should generally be reviewed during the comprehensive search, which focuses on source

documents containing primarily design basis information.

To capture the facility design requirements, the smart search scope may have to include facility

documentation that reflects the as-built design. Original design documents are preferred over

reconstituted as-built documents but are not always available. Sometimes these reconstituted as-built

documents use nameplate rating as the design requirement, lacking better information. This approach

presumes that the design is competent and the nameplate rating meets or exceeds the requirements

determined by the original design. In most cases, the structures, systems, and components (SSCs)

can continue to meet their nameplate ratings and detailed analysis of the original design requirement is
