mode of plant operation: A state of normal operation in a nuclear power plant such as starting up, power production, shutting down, maintenance, testing, and refuelling.

N

narrative log: A record of events and observations that is maintained by the duty station shift owner in the shift record and include information about the event, the affected components, and related entries.

O

OLC: See operating limits and conditions.
on-demand process: A set of readings that is required for a specific purpose at a duty station. The readings in an on-demand process supplement the routine readings that are required for shift rounds.
operating limits and conditions (OLC): See limiting condition for operation.
operational history: A record of the events that result in a change of component position or condition. The operational history is available in the component record but includes data from lineup, clearance, and duty station processes.
operational impact: The portion of an impact plan that defines the effect of planned maintenance on plant operations at the component, system, and plant levels.
operations shift review: An exercise that is carried out by the operations shift team during the initial stages of condition reporting. The review analyzes the reported condition, assesses the impact on plant operations, and provides information for the process of condition report screening.

P

permit: A record that defines work activities that are required to support work processes at a nuclear power plant.
position: The physical state of a location or an asset. A position is used to control the configuration of an asset or a location during lineup processes. A position is also used to control the configuration of a location during clearance processes.
positioning credit: A mechanism that is used during lineup execution to reuse a positioning event that belongs to another record and to fulfill a matching configuration requirement.
positioning exception: A mechanism that is used during lineup execution to fulfill the configuration requirement without positioning the component.

Q

quick asset: A simplified asset record that is intended for qualified usage by operations in configuration control processes, such as lineups or clearances.

reading frequency: The frequency with which readings must be taken to fulfill procedural requirements.
required qualification: A qualification that is associated with a specific function or additional role. The qualifications that are required for shift owners are defined in the duty station plan. Required qualifications are checked when the incoming shift owner is identified during turnover.
restoration condition: The configuration of plant equipment to satisfy a particular operational need.
revision plan: A record with which you can configure clearance components and work order relationships for future adoption as a clearance revision. You can also save and reuse portions of a clearance boundary.

Approves clearance restoration after Tagging Official approval is granted, and before the restoration of components in the field. The shift supervisor is generally a member of the operations staff. The requirement for shift supervisor approval of clearances before restoration is a configurable clearance option.

tech spec record: See technical specification record.
temp lift: The process of temporarily removing the tags or other devices, such as a lock, that are under the control of a clearance. Temp lifts can be used to conduct tests before the work is completed.
