Unit 2 PBAPS 1.0 DEFINITIONS (Cont'd)
(a) Initiating - A logic that receives signals from channels and produces decision outputs to the actuation logic.
(b) Actuation - A logic that receives signals (either from initiation logic or channels) and produces decision outputs to accomplish a protective action.
3 Logic System Functional Test - A Logic System Functional Test shall be a test of all logic components, i.e.,
all relays and contacts, all trip units, solid state logic elements etc., of a logic circuit, from sensor through and including the actuated device, to verify Operability.
The Logic System Functional Test may be performed by any series of sequential, overlapping or total system steps such that the entire logic system is tested.
Maximum Fraction of Limiting Power Density (MFLPD) - The Maximum Fraction of Limiting Power Density (MFLPD) is the highest value existing in the core of the Fraction of Limiting Power Density (FLPD).
MEMBERS OF THE PUBLIC - Members of the public shall include all persons who are not occupationally associated with the plant.
This category does not include employees of the utility, its contractors, or vendors.
Also excluded from this category are persons who enter the site to service equipment or to make deliveries.
This category does include persons who use portions of the site for recreational, occupational, or other purposes not associated with the plant.
i Minimum Critical Power Ratio (MCPR) - The minimum in-core critical power ratio corresponding to the most limiting fuel assembly in the Core.
Mode of Operation - A reactor mode switch selects the proper interlocks for the operational status of the unit.
The following l
are the modes and interlocks provided: Refuel Mode, Run Mode, Shutdown Mode, Startup/ Hot Standby Mode. l
