1.0 DEFINITIONS I

DEFINED. TERMS 1.1: The DEFINED TERMS of this section appear in capitalized type and

~

are applicable throughout these Technical Specifications.

THERMAL POWER

~1.2 THERMAL POWER shall be the total reacror core heat transfer rate

.to the reactor coolant.

RATED THERMAL POWER -

~

'1.3 RATED THERMAL POWER shall be a total reactor core heat transfer rate to the reactor coolant of 1825 MWt.

OPERATIONAL MODE 1.4 An OPERATIONAL MODE shall correspond to any one . inclusive combination of core reactivity condition, power level and average reactor coolant temperature.specified in Table 1.1.

1.5 Not used.

OPERABLE - OPERABILITY 1.6. A system, subsystem, train component.or device shall be OPERABLE or have OPERABILITY when it is capable of performing its design function (s).

~

Implicit in this definition shall be the assumption that all attendant instrumentation, controls, electric power, cooling or seal water,.

lubrication or other required auxiliary equipment is also OPERABLE.

.1.7 Deleted.

( DEFINITIONS CONTAINMENT INTEGRITY-1.8 CONTAINMENT INTEGRITY shall exist when:

1.8'11

. The containment automatic isolation valve system is OPERABLE..

1.8'.21 All penetrations required'to be closed during accident

. conditions are either:

a. . Capable of being closed by OPERABLE containment automatic isolation valves, or

.b. Closed by manual valves, blind flanges, or deactivated automatic valves secured and locked in their closed

. positions.

NOTE: Normally-closed isolation valves listed in Table ~3.11-2, which. fail closed on loss of power and are' capable of being closed within 60 seconds of a containment isolation actuation

. signal (CIAS) by an operator utilizing normal control switches-and normal position indication within the main control room may be opened for

. periodic testing.

.1.8.3- All equipment hatches are closed and sealed,-and-

1.8.4 ' Each door in each air lock is closed and sealed except when the air lock is being use'd for normal transit entry

-and exit through the containment, then at least one air.

lock door shall be closed and sealed.

CHANNEL CALIBRATION.

1. 9 - A CHANNEL CALIBRATION shall be the adjustment of channel output such d

.that it responds, with' acceptable range and accuracy, to known values  !

- of the parameter which the. channel measures. Calibration shall encompass the entire: channel,1 including equipment. actuation, alarm, or trip.

CHANNEL CHECK' ,

-i 1i10~ A CHANNEL CHECK shall'be the qualitative assessment of channel behavior during operation by observation. This~ determination shall include,-where possible, comparison of the channel indication with other indications derived from independent instrument channels l ' . measuring -the same parameter.
