ACTION:

- a. With an ATVS-RPT system instrumentation channel trip setpoint less conserva-tive than the value shown in the Allowable Value column of Table 3.3.4.1-2, declare the channel inoperable until the channel is restored to OPERABLE statuswiththechanneltripsetpointadjustedconsistentwiththeTrip betpoint value.
