1.2.10 TAVG is defined as the arithmetic average of the coolant temperatures in the hot and cold Icgs of the loop with the greater number of reactor coolant pumps operating if such a distinction of loops can be made.
-1.2.11 HEATUP - COOLDOWN MODE The heatup-cooldown mode is the range of reactor coolant temperature greater than 200 F and less than 525 F.
1.2.12 STATION, UNIT, PLANT AND FACILITY Station, unit, plant and facility as used in these technical specifications all refer to TMI Unti 1.
1.3 OPERABLE A system, (i.e. subsystem, train, component or device) shall be operabic or have operability when it is capable of performing its specified function (s). All i
