1 Scope
2 Purpose
3 Definitions
4 Discussion
4.1 Minimum separations between setpoints
4.2 Typical types of systems
Annex A - (informative) References
Figures
1 - Instrument channel layout for the generalized
system
2 - Illustration of relationships that may apply in
determining minimum separations of setpoints for
sequenced actions
3 - Instrument channel layout for system having high
pre-trip and high trip bistables driven by the same
transmitter
4 - Setpoint relationships for interrelating high pre-trip
and high trip bistables driven by the same transmitter
with example values for a typical PWR pressurizer
pressure system
5 - Instrument channel layout for system having high and
low alarm bistables driven by the same transmitter
6 - Setpoint relationships for interrelating high and low
alarm bistables driven by the same transmitter, with
example values for a typical spray pond level system
7 - Instrument channel layout for system having high and
low pre-trip bistables all driven by the same transmitter
8 - Instrument channel layout for system having high pre-
trip and trip bistables driven by one transmitter and
low pre-trip and trip bistables driven by a different
transmitter
9 - Setpoint relationships for interrelating high and low
pre-trip and trip bistables driven by the same or
different transmitters, with example values for typical
PWR pressurizer pressure systems
10- Instrument channel layout for system having high and low
alarm bistables driven by one transmitter and a low-low
trip bistable driven by a different transmitter
11- Setpoint relationships for interrelating high and low
alarm bistables driven by one transmitter and a
relating low-low trip bistable driven by a different
transmitter, with example values for a typical
refueling water tank level system
Provides guidance on the handling of setpoints for sequenced actions in both nuclear safety-related and nuclear power plant non-safety-related instrumentation.
