K.
Instrument Check - An instrument check is the cpalitative determination of acceptable operability by observation of instrument behavior citring operation.
%is determination shall include, where possible, comparison of the instrument with other independent instruments measuring the same variable.
L.
Instrument R1rctional 'Iest - An instrument functional test means the injection of a sinulated signal into the instrument primary sensor to
~
verify the proper instrup At channel response, alarm and/or initiating action.
M.
Limitirg Conditions fo Operation (LCD) - %e limiting conditions for operation specify the acceptable levels of system performance necessary to asaire safe startup and operation of the Unit. When these conditions are met, the Unit can be operated safely and abnormal situations can be safely controlled.
N.
Limiting Safety System Settirg (ISSS) - %e limiting safety system settings are settirgs on instrumentation which initiate the a2tomatic protective action at a level such that a Safety Limit will not be exceeded.
The region between the Safety Limit and these settings represents margin with normal operation lying on the conservative side of these settings.
The margin has been established so that with proper operation of the instrumentation the Safety Limits will never be exceeded.
O.
Iogic System Rinctional Test - A logic system functional test means a test of all relays and contacts of a logic circuit from sensor to activated device to inaire that components are operable per design intent.
Where practicable, action will go to ccxnpletion; e.g.,
pumps will be started and valves opened.

Operable-Operability - A system, albsystem, train, component, or device shall be operable or have operability when it is capable of performirg its specified function (s).
Implicit in this definition shall be the asaingtion that all necessary attendent instrumentation,
- controls, normal and emergercy power sources, cooling or seal water, lubrication or other auxiliary equignent that are reglired for the system,
=
albsystem, train, ccznponent or device to perform its function (s) are also capable of performing their related support function (s).
When a system, albsystem, train component or device having Technical g
Specification operability recpirements is determined to be inoperable g
solely because its emergency power.nirce is inoperable, or solely oo beca1se its normal power source is inoperable, it may be considered
$8 operable for the pirpose of satisfyiry the realirements of its mg applicable Limiting Condition for Operation, provided:
(a) its m
corre@onding rormal or emergency power source is operable and (b) all M
its rec 11ndant system (s),
albsystem(s),
train (s) component (s) and 0,g device (s) recpired to perform its intended function are operable, or en likewise satisfy the recpirements of this specification.
Unless both
$g conditions (a) and (b) are satisfied, enter the applicable Limitirg Cbndition for Operation as @ecified by the Technical Specifications or within two hours action shall be Jnitiated to place the unit in at least Hot Sh.Itdown within the next 12 hourc, and in at least Cold Shirdown within the followirg 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
