Logical Connectors 1.2 1.0 USE AND APPLICATION 1.2 Logical Connectors PURPOSE The purpose of this section is to explain the meaning of logical connectors.
Logical connectors are used in Technical Specifications (TS) to discriminate
- between, and yet connect, discrete Conditions, Required
- Actions, Completion
- Times, Surveillances, and Frequencies.
The only logical connectors that appear in TS are AND and QR.The physical arrangement of these connectors constitutes logical conventions with specific meanings.
BACKGROUND Several levels of logic may be used to state Required Actions.
These levels are identified by the placement (or nesting) of the logical connectors and by the number assigned to each Required Action.
The first level of logic is identified by the first digit of the number assigned to a Required Action and the placement of the logical connector in the first level of nesting (i.e.,
left justified with the number of the Required Action).
The successive levels of logic are identified by additional digits of the Required Action number and by successive indentations of the logical connectors.
When logical connectors are used to state a Condition.,
Completion Time, Surveillance, or Frequency, only the first level of logic is used, and the logical connector is left justified with the statement of the Condition, Completion Time, Surveillance, or Frequency.

EXAMPLES The following examples illustrate the use of logical connectors.
EXAMPLE 1.2-l ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A.
LCO not met.
A.1 Verify AND A.2 Restore In this example the logical connector AND is used to indicate that when in Condition A, both Required Actions A.1 and A.2 must be completed.

EXAMPLE 1.2-2 ACTIONS CONDITION A.
LCO not met.
REQUIRED ACTION A.1 Trip OR A.2.1 Verify AND A.2.2.1 Reduce...
OR A.2.2.2 Perform OR A.3 Align COMPLETION TIME This example represents a more complicated use of logical connectors.
Required Actions A.l, A.2, and A.3 are alternative
- choices, only one of which must be performed as indicated by the use of the logical connector QR and the left justified placement.
Any one of these three Actions may be chosen.
If A.2 is chosen, then both A.2.1 and A.2.2 must be performed as indicated by the logical connector AND.
Required Action A.2.2 is met by performing A.2.2.1 or A.2.2.2.
The indented position of the logical connector QR indicates that A.2.2.1 and A.2.2.2 are alternative
- choices, only one of which must be performed.
