APPENDIX B - GLOSSARY
As-built documentation. Documentation (for example, Piping and Instrument Diagrams, and database
records) verified by physical inspection as depicting the actual physical configuration and verified as
consistent with the design requirements.
As-found. Information, often in the form of marked-up documents that reflects the actual physical
configuration and identifies any discrepancies with currently approved facility documentation.
Assessment. For engineering applications, the process of estimating the value of something using
authoritative expert judgment based upon observations of representative cases and rough calculations,
rather than determining the exact value based upon comprehensive and detailed examinations, and precise
and rigorous complete calculations.
Authorization agreement. A documented agreement between DOE and the contractor for high-hazard
facilities (Hazard Category 1 and 2), incorporating the results of DOE's review of the contractor's proposed
authorization basis for a defined scope of work. The authorization agreement contains key terms and
conditions (controls and commitments) under which the contractor is authorized to perform the work.
Authorization basis. Those aspects of the facility design basis considered important to the safety of facility
operations and therefore relied on by DOE to authorize operation. The authorization basis is described in
documents such as the facility documented safety analysis and other safety analyses, hazard classification
documents, the Technical Safety Requirements, DOE-issued safety evaluation reports, and facility-specific
commitments made in order to satisfy DOE Orders or policies.
Change. Any alteration or addition, temporary or permanent, to the facility physical configuration, facility
documentation, or design requirements is considered to constitute a change. Changes not within current
design requirements involve design changes. Identical replacements are not changes.
Change control. A process that ensures all changes are properly identified, reviewed, approved,
implemented, tested, and documented.
Change control package. The change control package is the documentation that accompanies a change to a
facility, activity, or operation from the planning and initiation through completion of the implementation
and testing. The change control package documents the following as applicable:
The description of the proposed change sufficient to support technical and management reviews
prior to approval;
The name and organization of the requester;
The description of the potentially affected SSCs;
The reason for the proposed change and any known schedule issues;
A list of the alternative solutions considered and the results;
The date by which the decision about the change needs to be completed to facilitate timely
implementation or to allow implementation to occur concurrent with other activities, such as a
planned maintenance shutdown;
Any other information needed to review, track, approve, or process the proposed change.
It also includes related information such as:
