1.0 DEFINITIONS (Continued)

U.

Surveillance Freguency - Each Surveillance Requirement shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25 percent of the specified surveillance interval.

-The Surveillance Frequency establishes the limit for which the specified time interval for Surveillance Requirements may be extended.

It permits an allowable extension of the normal surveillance interval to facilitate surveillance schedule and consideration of plant operating conditions that may not be suitable for conducting the surveillance; e.g., transient conditions or other ongoing surveillance or maintenance activities.

It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling outages.

The limitation of Definition "U" is based on engineering judgment and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the Surveillance Requirements.

This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.

V.

Surveillance Interval - The surveillance interval is the calendar timo between surveillance tests, checks, calibrations, and examinations to be performed upon an instrument or component when it i

is required to be operable.

These tests may be waived when the 1

instrument, component, or system is not required to be operable, but the instrument, component, or system shall be tested prior to being declared operable. The operating cycle interval is 18 months and the 25% tolerance given in Definition "U" is applicable.

H.

Fire Sunoression Water System - A fire suppression water system shall consist of: a water source (s); gravity tank (s) or pump (s);

and distribution piping with associated sectionalizing control or isolation valves.

Such valves shall include hydrant post indicator valves and the first valve ahead of the water flow alarm device on each sprinkler, hose standpipe or spray system riser.

X.

Staggered Test Basis - A staggered test basis shall consist of:

(a) a test schedule for D systems, subsystems, trains, or other i

designated components obtained by dividing the specified test interval into n equal subintervals; (b) the testing of one system, subsystem, train or other designated components at the beginning of each subinterval.

Y.

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

Offsite Dose Calculation Manual (ODCM) - An offsite dose calculation manual (ODCM) shall be a manual containing the current methodology and parameters to be used for the calculation of offsite doses due to i

l radioactive gaseous ard liquid effluents, the calculation of gaseous and liquid effluent monitoring instrumentation alarm / trip setpoints, and the conduct of the Radiological Environmental Monitoring Program.

AA.

Action - Action shall be that part of a specification which prescribes remedial measures required under designated conditions.

persons who are not occupationally associated with the plant.
