Identification and Retrieval of Design Information

DOESTD107393

1.3.6.2 Identification and Retrieval of Design Information

The identification and retrieval of design information should be accomplished in stages, with emphasis

on the most important and most accessible information first.

Identification and Retrieval of Source Documents. The objective and scope of source documents

to be reviewed should be defined for each document identification and retrieval stage. The

recommended stages are the formal review, the smart search, and the comprehensive search.

The formal review should address those on-hand documents, such as the facility safety analysis

and TSRs, that contain summary-type design information; the smart search should identify and

retrieve those types of documents that can be identified as most likely to contain design

requirements; and the comprehensive search should identify and retrieve any remaining

documents that might contain design information, including DOE correspondence and vendor

correspondence.

Extraction of Design Information. Technical review and identification of design information from

each source document should include both design requirements and design basis information.

Extracted design information should be identified as to the applicable facility SSC, type of SSC,

technical topic area, and whether it is a design requirement or design basis. The technical review

and identification of design information from each source document should be complete, such

that the document does not have to be reconsidered during subsequent searches and reviews.

1.3.6.3 Evaluation, Verification, and Validation of Design Information

Extracted design information should be verified by a second party to ensure that the design information

was extracted completely and accurately from the source documents. Extracted design information

should be technically validated to ensure that it is reasonable, that it is applicable to the current facility

mission and configuration, and that the analytical methods and technical assumptions used in the

design process are valid and appropriate. Design basis information should be correlated with the

design requirements. Extracted design information should also be evaluated to identify any missing

design requirements or design basis information. Design Information Summaries should be field

validated to ensure that design requirements are properly reflected in the physical configuration and in

the associated facility documentation.

1.3.6.4 Discrepancy Resolution

Validated situations involving the following should be documented as open items: apparent

contradictions in the information from different source documents; concerns; unanswered technical

questions; and cases of missing, undocumented, or inaccurate information. The open items should be

dispositioned by a formal resolution process and should be tracked to completion and closeout,

including documentation of their resolution. Safety-significant open items (i.e., discrepancies) should

be promptly addressed by existing programs for determining operability and reportability and resolved

by those programs.

1.3.6.5 Regeneration of Missing Critical Design Information

Missing design information should be evaluated to determine which part needs to be regenerated.

Missing design information that is critical, including that necessary to support the facility accident

analysis and TSRs, should be regenerated in order of priority.
