PBAPS 1.0 DEFINITIONS t
The succeeding frequently used terms are explicitly defined so that a uniform interpretation of the specifications may be achieved.
Alteration of the Reactor Core - The act of moving any component in the region above the core support plate, below the upper grid and within the shroud with the vessel head removed and fuel in the vessel.
Normal control rod movement with the control drive hydraulic system is not defined as a core alteration.
Normal movement of in-core instrumentation and the traversing in-core probe is not
-defined as a core alteration.
Channel - A channel'is an arrangement of a sensor and associated components used to evaluate plant variables and produce discrete, outputs used in logic.
A channel terminates and leses its identity where individual channel outputs are combined in logic.
Cold Condition - Reactor coolant temperature equal to or less than 212 F.
Cold Shutdown - The reactor is in the shutdown mode, the reactor coolant temperature equal to or less than 212 F, and the reactor vessel is vented to atmosphere.
Critical Power Ratio (CPR) - The critical power ratio is the
' ratio of that assembly power which causes som.e. point in the assembly to experience transition boiling to-the assembly power at the reactor condition of interest as calcu' lated by application of the GEXL correlation.
(Reference NEDO-10958).
Dose Equivalent I-131 - That concentration of I-131 (Ci/gm) which alone would produce the same thyroid dose as the quantity and isotopic mixture of I-131, I-132, I-133, I-134, and I-135 actually present.
