17.2.1 Identification of Safety-Related Features The Watts Bar Nuclear Plant Q-List is a listing of structures, systems, and components covered by the Nuclear Quality Assurance program as set forth in the Nuclear Quality Assurance Plan, TVA-NQA-PLN89-A.
The term Q-List refers to a report available in the Master Equipment List (MEL) that indicated component safety classifications.
The Q-List consists of a combination of an itemized section and notes. Items addressed on this list are handled in accordance with the TVA Quality Assurance Program. The Q-List contains safety-related features. Safety-related features are those structures, systems, and components that are necessary to ensure:
- 1.
The integrity of the reactor coolant pressure boundary.
- 2.
The capability to shut down the reactor and maintain it in a safe condition.
- 3.
The capability to prevent or mitigate the consequences of an incident which could result in potential offsite exposures comparable to those specified in 10 CFR 100.
Additionally, the Q-List includes quality-related and some non quality-related features which are not safety-related. TVA identified quality-related features are also defined by the TVA Nuclear Quality Assurance Plan.
The Q-List is in a QA software database, as a computer generated list and is maintained per engineering site procedure. Hard copy reports, (i.e., Q-List), are extracted from the data base and can be issued as controlled design outputs. The data is accessible from computer terminals throughout the plant.
In addition, a site wide procedure provides guidelines for using the WBN Q-List to determine the 10CFR 50, Appendix B QA program application. Q-List changes are controlled through the design change process/administrative process to ensure continued completeness and accuracy.
