Simu_ lated Automatic Actuation - Simulated automatic actuation means applying a simulated signal to the sensor to actuate the circuit in question.

Site Bound - That line beyond which the land is not owned, Icased or otherwise controlled licensee.

Source Check - A source check shall be the qualitative assessment of channel response when the cfiinnel sensor is exposed to a radioactive source.

$_t_artup/Ilot Sthndhy Mode -- In this mode the reactor protection scram trips, initiated by conHeiiser low vacuum and main steam line isolation valve closure are bypassed, the reactor protection system is energized with IRH neutron monitoring system trip, the APRM 15% high flux trip, and control rod withdrawal interlocks in service. This is often referred to as just Startup Mode. This is intended to imply the Startup/llot Standby position of the mode switch.

Surveillance frequency - Periodic surveillance tests, checks, calibrations, and examinations sfEli be performed within the specified surveillance intervals. Specified periodic surveillance Intervals are defined as:

Survelliance tests are not I required on systems or parts of the systems that are not required to be operable or are tripped. If tests are missed on parts not required to be operabic or are tripped, then they shall be performed prior to returning the system to an operable status.

A surveillance test of the diesel generators, that requires a plant outage, may be deferred beyond the calculated due date until the next refueling outage, provided the equipment has been similarly tested and meets the surveillance requirement for the other unit.

l Transition Boiling - Transition bolling means the boiling regime between nucleate and film boiling. 1ransition boiling is the regime.in which both nucleate and film boiling cccur interuittently with neither type being completely stable.
