.. need to design a way to bring in multiple glossary data sources so that we can use the global shared glossary + our project specific glossary ######### Glossary ######### Glossary .. glossary:: Configuration Management The process of identifying and documenting the characteristics of a facility's structures, systems and components (including computer systems and software), and of ensuring that changes to these characteristics are properly incorporated into the facility documentation. :cite:p:`agencyInformationTechnologyNuclear2010` Controlled document Documents whose content is maintained uniform among the copies by an administrative control system. The goal of controlling documents is to ensure that work is performed using approved current information, not obsolete information. Important documents to be controlled are uniquely identified (including revision number, date, and specific copy number), and distribution is formally controlled. Revisions to controlled documents are uniquely tracked and implemented, including mandatory page replacements and receipt acknowledgment. Controlled documents typically include procedures for operations, surveillance, and maintenance, and safety basis documents such as the SAR, and hazard and accident analyses. :cite:p:`agencyInformationTechnologyNuclear2010` Design basis The range of conditions and events taken explicitly into account in the design of a facility, according to established criteria, such that the facility can withstand them without exceeding authorized limits by the planned operation of safety systems. :cite:p:`agencyInformationTechnologyNuclear2010` Design control Measures established to ensure that the information from design input and design process documents for structures, systems, and components is correctly translated into the final design. :cite:p:`agencyInformationTechnologyNuclear2010` Document A written collection of information, instructions, drawings, specifications, etc. that is *maintained* throughout the design/operation/decommissioning of the facility. Differs from a *record* in that it is expected to be *maintained* by revisions as needed. See :need:`R_APPB_45` Record A written collection of information providing evidence of work that was done at a specific time. Records are expected to be *retained* for a certain retention period, e.g. for the lifetime of the plant or for a given number of years. See :need:`R_APPB_79`
